[Industrial applications]

 The present invention relates to an ice tray.

[Prior art]

 2. Description of the Related Art Conventionally, as an ice tray for making ice in a refrigerator for home use, a recess for putting water (hereinafter, referred to as “ice recess”) is a cube or a rectangular parallelepiped. Since it is often desired to make ice quickly, it would be convenient to have an ice tray that can make ice in a shorter time than conventional ice trays. In addition, water expands when it freezes, but in the case of a conventional cube or rectangular parallelepiped ice tray, the expanded ice receives a drag force from the vertical inner wall of the ice making recess in the direction of sandwiching the ice. Therefore, there is a drawback that it is difficult to remove the ice from the ice tray after the ice making.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide an ice tray that can make ice in a shorter time than conventional ice trays and that can easily take out ice after ice making.

[0004]

[Means for Solving the Problems]

 The present invention provides an ice tray having at least one substantially cone-shaped ice making recess.

In this specification, a “cone” is a curved surface or some of a curved surface formed by a straight line connecting a point that goes around the circumference of a closed curved line or a broken line on a plane and a certain point outside this plane. It refers to the part of the space surrounded by a part of the plane, and includes pyramids and cones such as triangular pyramids, quadrangular pyramids, and pentagonal pyramids. Among these, particularly preferable ones are pyramids, that is, regular pyramids. “Substantially pyramidal” means, for example, a pyramid with its corners rounded, a pyramid with a thick bottom surface, or any other non-critical modification of the pyramid. It is also used to mean that

The ice tray of the present invention has at least one cone-shaped ice-making concave portion, preferably dozens or dozens. It should be noted that the cones forming the ice making concave portion are necessarily arranged so that the tops of the cones form the bottom of the ice tray.

【Example】

 Hereinafter, the ice tray of the present invention will be described more specifically with reference to the drawings. FIG. 1 schematically shows an embodiment of the ice tray of the present invention. In this embodiment, the ice tray 10 has a plurality of substantially square pyramid ice making recesses 12. The top of the ice making recess (bottom of the pyramid) has a thickness, but this is to increase the strength of the ice making tray and is not always necessary.

FIG. 2 shows a state of producing substantially regular octahedral ice by using the two ice trays shown in FIG. In this case, the ends of the two upper and lower ice trays are fixed with something like a clip 14. In addition, in the case of using in this mode, a water injection port (not shown) may be provided in the ice tray used as the upper plate, and the upper and lower ice trays may be combined as shown in the drawing, and then water may be put into the inside.

[0009]

[Effect of device]

 In the ice tray of the present invention, the ice making concave portion has a conical shape, and has a larger surface area per unit volume, that is, an area in contact with cold air, as compared with a conventional ice making tray having a cube or rectangular parallelepiped ice making concave portion. Therefore, ice can be produced in a shorter time than the conventional ice tray. Further, in the ice tray of the present invention, when the water expands, the drag force received from the inner wall of the ice making recess has a component force in the direction of pushing the ice above the ice tray. It has an advantage that ice can be easily pushed out.
