Detailed Description
The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiment is not intended to limit the present invention, and structural, methodological, or functional modifications of the invention according to the embodiment are included in the scope of the invention.
(description of ice making apparatus)
Fig. 1 is a perspective view of an ice making apparatus of the present invention, fig. 2 is a sectional view taken along line A-A of fig. 1, and fig. 3 (a) to 3 (b) are perspective views of an ice making tray 103 and a fitting 101 of the ice making apparatus of the present invention, and the ice making apparatus of the present invention will be described with reference to fig. 1 to 3.
As shown in fig. 1, the ice making tray 103 has a partition 105 and is embedded therein in conformity with the shape of the fitting 101. The ice making tray 103 is made of a resin such as a thermoplastic resin. The ice making tray 103 is made of an elastically deformable material.
The ice making tray 103 is preferably divided into a plurality of cells by partitions 105; the partition 105 is preferably grooved to allow water to be distributed throughout.
Fitting 101 is preferably a resin containing a metallic or thermally conductive filler to enhance thermal conductivity. The metal is preferably magnetic, and an alloy of iron, nickel, cobalt, or the like can be used. On the other hand, a metal such as aluminum that is not magnetic is also possible.
The heat conductive filler is a substance having high heat conductivity, such as boron nitride and aluminum oxide. The incorporation of a thermally conductive filler into the resin can increase thermal conductivity. The heat conductive filler and the resin are not magnetic but can be used as the fitting 101.
As shown in fig. 2, the inner surface of the fitting 101 is in contact with the outer surface of the ice making tray 103. Not only the bottom surface but also the side surfaces are in contact, so that the contact area can be increased, the thermal conductivity can be increased, and the ice making time can be shortened.
As shown in fig. 3 (a) and 3 (b), the fitting 101 and the ice making tray 103 are detachably provided. The groove 107 of the fitting 101 is fitted in matching with the shape of the partition 105 of the ice making tray 103, thus increasing the contact area and enabling the ice making time to be shortened.
The ice-making device composed of the fitting 101 and the ice-making tray 103 is automatically or manually filled with water in a state of being put into the refrigerator. Water injected from one or more passes through the grooves of the partition 105 and ice is formed in all of the plurality of partitions.
By the metal or heat conductive filler of the fitting 101 contacting the ice making tray 103, heat release performance can be improved and ice making time can be shortened. Further, since the ice making tray 103 is made of resin, it is possible to elastically deform and twist-de-ice.
(Ice tray with magnet embedded therein)
Fig. 4 is a cross-sectional view of an ice-making tray having magnets embedded therein according to an embodiment of the present invention. An ice making tray having a magnet embedded therein according to an embodiment of the present invention will be described with reference to fig. 4.
As shown in fig. 4, a magnet 109 is embedded in the ice making tray 103. When the magnet 109 is embedded in the ice making tray 103, the contact pressure between the ice making tray 103 and the contact area of the attachment 101 can be increased when the attachment 101 has magnetism. In order to increase the contact pressure, the magnet 109 is preferably embedded in the bottom surface of the ice making tray 103.
In the case where the fitting 101 is made of a metal having magnetism, the contact pressure can be increased by attaching the magnet 109 to the ice making tray 103, and the increase in contact pressure can improve the heat conductivity.
(Ice tray with claw portion)
Fig. 5 (a) is a cross-sectional view of an ice making tray provided with a claw portion according to the present invention, fig. 5 (b) is a side view of an ice making tray provided with a claw portion, fig. 5 (c) is a side view of an attachment provided with a hole portion to be engaged with the claw portion, and an ice making tray 103 provided with a claw portion to be engaged with the attachment 101 will be described with reference to fig. 5 (a) to 5 (c).
As shown in fig. 5 (a), the ice making tray 103 of the present invention is provided with a claw portion 111, and as shown in fig. 5 (b), the claw portion 111 is preferably provided on a surface of the ice making tray 103 side. As shown in fig. 5 (c), the fitting 101 is provided with a hole 117 engaged with the claw portion 111.
When the claw portion that engages with the fitting 101 is provided at the end portion of the ice making tray 103, the contact pressure of the contact area between the ice making tray 103 and the fitting 101 can be increased, and the heat conductivity can be further improved by increasing the contact pressure.
(deicing action)
Fig. 6 is a schematic view of an ice-making tray twisted for ice-breaking. Fig. 7 is a view of an ice making tray twisted for ice detachment and a fitting coupled with the ice making tray. The ice-removing operation after ice making will be described with reference to fig. 4 to 7.
As shown in fig. 6, the ice-making tray 103 has a first rotating shaft bar 113 and a second rotating shaft bar 115 for automatic ice-removing. The ice making tray 103 is rotated by an ice removing mechanism performing a rotational operation such as a motor mounted at the first rotation shaft bar 113, and the second rotation shaft bar 115 is freely rotated with the rotation of the first rotation shaft bar 113.
The ice making tray 103 has a stopper 119, and the ice making tray 103 is twisted by the stopper 119 striking against a part of the ice removing mechanism and preventing rotation. After ice is made, the ice making tray 103 is rotated, and the ice making tray 103 is rotated continuously from a state in which the ice making tray 103 is vertical, so that the ice making tray 103 and the partition 105 are twisted, and further, the ice is separated, and the separated ice falls down and is collected in a tray (not shown) of the refrigerator.
As shown in fig. 7, the ice making tray 103 rotates together with the attachment 101, and the ice making tray 103 is fixed by a claw 121 provided on the attachment 101. The first rotation shaft rod 113 and the second rotation shaft rod 115 rotate, but the fitting 101 is fixed by the claw portion 121 and thus rotates simultaneously. When the ice making tray 103 is in a vertically erected state, the stopper 119 collides with a part of the ice removing mechanism, thereby preventing the rotation of the ice making tray 103 and the accessory 101.
The ice making tray 103 is twisted to disengage the ice making tray 103 from the fitting 101. In the case where the magnet 109 or the claw portion 111 is provided at the ice making tray 103, the force at the magnet 109 or the claw portion 111 is opposed by the torsion force of the ice removing mechanism, and the contact in the contact area of the ice making tray 103 and the fitting 101 is released.
When the ice making tray 103 is twisted, the contact of the ice making tray 103 with the fitting 101 is released. Thus, the fitting 101 does not need deformability.
In the case of the ice making tray 103 shown in fig. 7, the magnet 109 is preferably located away from the attachment 101. That is, when the magnet 109 is positioned at four corners of the ice making tray 103, it is preferable that it is positioned at one side of the first rotation shaft bar 113 in fig. 7, below the upper-side partition 105 at the twisted side, and is positioned at the proximal end and at the right side of the first rotation shaft bar 113 in fig. 4.
Also, in the case where the claw portions 111 are at the four corners of the ice making tray 103, they are preferably located at one side of the first rotation shaft bar 113 in fig. 7, at the twisted side of the upper side, and at the proximal end in fig. 5 (b).
When the ice making tray 103 twisted by the ice removing mechanism is returned to the original state, that is, when the ice making tray 103 is returned to the horizontal position by the reverse rotation, the contact area of the ice making tray 103 and the fitting 101 is restored to contact.
Here, in the case where the magnet 109 or the claw portion 111 is provided, the contact pressure in the contact region can be further increased.
The claw portion 111 is elastically deformed and resumes contact between the ice making tray 103 and the accessory 101 when the ice making tray 103 is twisted back. Further, the magnet 109 is again attracted to the fitting 101 when the ice making tray 103 is twisted back, and resumes the contact of the ice making tray 103 with the fitting 101. In this way, the contact of the ice tray 103 with the fitting 101 is restored, and the contact pressure is increased again.
(fitting in another embodiment of an ice-making device)
Fig. 8 is a sectional view of another embodiment of the ice making device of the present invention, and a fitting 101 according to another embodiment of the present invention will be described with reference to fig. 8.
As shown in fig. 8, fitting 101 may also be free of grooves 107. That is, the contact area may be formed between the inner side of the attachment 101 and the outer side of the ice tray 103, at least a part of the side surfaces and the bottom surface. By so doing, it is also possible to increase the thermal conductivity and to shorten the ice making time.
The ice making device of the present invention is as easy as the conventional ice making device in removing ice; further, the heat release performance of the ice making device is improved and the ice making time is shortened.
The above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention.
