Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rotary ice-removing type ice-making device that removes ice by twisting an ice-making tray made of a flexible material.

[Prior art]

In a conventional rotary ice-taking type ice-making device, an ice-making tray 4 made of a flexible material is mounted on a shaft on top of frames 2 and 3 installed in a freezer compartment 1, as shown in FIGS. 4 to 6. Ice making frame 7 rotatably supported at 5 and 6
is attached so that it can be inserted and removed freely.

A coiled spring 10 is loosely fitted to the shaft 6 at the rear of the ice tray 4, and normally the ice tray 4 is biased counterclockwise, and the ice tray 4 that has been supplied with water is supported in the ice making frame 7.
When the ice cube tray 4 is inserted into the frames 2 and 3 of the freezer compartment 1, the ice cube tray 4 is tilted to prevent water from spilling.

When ice making is completed and ice is to be removed, hold the handle 8 and rotate it clockwise.
The rear part of the ice tray 4 is prevented from rotating by a stopper 9 provided at the rear of the ice making frame 7, but the front part of the ice tray 4 is still rotatable. As a result, the ice tray 4 made of a flexible material is twisted, and the ice is removed.

Also, Utility Application No. 59-92993 (Utility Application No. 57-14773)
The micro film of No.) is an ice-making device in which at least one of the ice-making tray 5 or the ice-making frame 1 is provided with a blocking means that allows the rotation of the ice-making tray 5 only when a rotational force of a predetermined amount or more is applied to the ice-making tray 5. is proposed.

[Problem that the invention attempts to solve]

However, in the case of the structure described above, in order to prevent the ice making tray 4 from easily rotating and water spilling when pouring water or inserting and removing the ice making frame 7 into the frames 2 and 3, the steps shown in FIG. As shown in Fig. 6, a coiled spring 10 is provided on the shaft at the rear of the ice tray 4 to solve the problem, which results in poor assembly workability, an increase in the number of parts, and high costs. Ta.

Furthermore, although the ice making device described in the above-mentioned Utility Model Application No. 1987-92993 is designed to prevent the ice making tray 5 from rotating unless a rotational force exceeding a predetermined level is applied, there is no locking device or the like. However, there was a problem in that the ice tray 5 would rotate if a rotational force exceeding a predetermined value was applied.

The present invention has been made to solve these problems, and includes forming deformable resin springs 19 and 18 integrally with the ice tray 13 at the front and rear edges of the ice tray 13, and A protrusion 20 for locking the resin spring 19 is provided on the frame 11 at a position facing the resin spring 19 to prevent the ice tray 5 from rotating inadvertently unless the ice tray 5 is pressed backwards. The purpose is to provide an ice-free ice tray.

[Means for solving problems]

In order to achieve the above purpose, this idea was developed to include an ice making frame that can be inserted into and removed from the frame installed in the freezer compartment.
An ice tray made of flexible material is rotatably supported,
In a rotary ice-making ice tray in which ice is removed from the ice-making tray by twisting the ice-making tray, deformable resin springs are formed integrally with the ice-making tray at the front and rear edges of the ice-making tray, and , a protrusion for locking a resin spring formed on the front edge is provided at a position facing the resin spring on the front edge of the ice-making frame, thereby regulating rotation of the ice-making tray. do.

[Effect]

In the above configuration, the resin spring provided on the rear edge of the ice tray presses the ice tray forward, and prevents the resin spring provided on the front edge of the ice tray from engaging with the protrusion provided on the ice making frame. This prevents the ice tray from being rotated inadvertently unless the ice tray is pushed backwards and the resin spring at the front edge is removed from the protrusion.

Furthermore, since the resin spring can be molded integrally with the ice tray, it can be manufactured at low cost and does not interfere with the rotation of the ice tray.

〔Example〕

Reference numeral 11 denotes an ice making frame with a stopper 12 protruding from its rear end, and rotary shafts 14, 1 protruding from the front and rear edges of an ice making tray 13 made of a flexible material.
5 is rotatably inserted, and a handle 17 is detachably attached to the tip of a protruding shaft 16 that is locked to the upper front edge of the ice making frame 11 from the front rotating shaft 14 and one side of the ice making tray 13. is attached to. and,
The ice making tray 13 can be easily separated from the ice making frame 11 with the handle 17 removed.

Further, the ice tray 13 has resin springs 18 and 19 having some elasticity integrally formed at the front and rear edges at positions shifted left and right about the rotating shafts 14 and 15. Further, the rear resin spring 18 is pressed against the inner surface of the rear end of the ice making frame 11, and the front resin spring 19 is pressed against the inner surface of the rear end of the ice making frame 11.
It is adapted to be locked onto a protrusion 20 formed on the inner surface of the front end of 1.

When the ice tray 13 is in its normal position, that is, in the horizontal position, the ice tray 13 is pressed by the rear resin spring 18 and the front resin spring 19 is locked.
prevents accidental rotation. Also, when taking off the ice, hold the handle 17 and push the ice tray 13 backward to release the engagement between the resin spring 19 and the protrusion 20 on the front edge of the ice tray 13, and then rotate the ice tray 13 clockwise. let Then, as the ice making tray 13 rotates, the resin spring 18 at the rear edge comes off from the ice making frame 11, and there is no need to press the ice making tray 13 backward.

When the ice tray 13 rotates nearly 180 degrees, the right rear edge of the ice tray 13 hits the lower surface of the stopper 12 and cannot rotate. From this state, if the handle 17 is further rotated, for example, 90 degrees clockwise,
The ice tray 13 is twisted to release the ice, and the ice falls.

Note that the rotation of the ice tray 13 in the counterclockwise direction is the opposite of the above operation.
The abutting portions 8 and 19 are rounded so as not to interfere with the rotational movement of the ice tray 13.

〔effect〕

Since the present invention is constructed as described above, it is possible to prevent the ice tray from inadvertently rotating without using a separate member such as a conventional spring. Since it is molded, productivity is high, and it has the remarkable effect of reducing costs by reducing the number of parts.
