BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice-maker having a freezing heater, and more particularly to an ice-maker having a freezing heater including a direct-connection type high-efficiency freezing heater.

Generally, a refrigerator has a refrigerating chamber for refrigerating and storing food and a freezing chamber for refrigerating and storing food. At this time, an ice maker for producing ice is installed in the freezing room or the refrigerating room.

A conventional ice-maker for a refrigerator has a heater at a lower portion of the ice tray. When the ice-making is completed, the heater slightly melts the ice that is tightly coupled with the inner surface of the ice tray, thereby allowing the ice to be released. Although a U-shaped sheath heater is used as the heater, the sheath heater has a small area of direct contact with the ice tray, and the diameter of the tube constituting the sheath heater is large, Spacing. Therefore, in the case of the sheath heater, the heat transfer efficiency is lowered, so that it takes much time and power to melt the ice in the ice tray.

To solve this problem, a planar heater using a metal thin film as a resistor may be used. In order to supply power to the surface heater, a lead wire is required to connect the surface heater and the power source. However, since the metal of the lead wire should not be exposed to the outside, a separate structure for electrically insulating both ends of the lead wire is required. As a result, the cost of the ice maker rises and the manufacturing process becomes troublesome.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a heater and an ice maker having the same according to embodiments of the present invention will be described with reference to FIGS. 1 to 10. FIG. However, this is an exemplary embodiment only and the present invention is not limited thereto.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for efficiently describing the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

1 is a cross-sectional view of an ice maker 100 according to an embodiment of the present invention.

Referring to FIG. 1, an ice maker 100 includes an ice tray 102, an ejector 104, a freezing heater 120, and a control box 110.

The ice tray 102 may have an ice-making space for receiving water therein. A plurality of partition walls are formed in the ice tray 102 to divide the ice making space into a plurality of spaces. At this time, each separated ice-making space in the ice tray 102 may be formed corresponding to the ejector pin 104-2. The inner circumferential surface of the ice tray 102 may be provided in a semicircular shape having a radius corresponding to the length of the ejector pin 104-2 so that the ejector pin 104-2 can rotate and release ice. The ice tray 102 may be formed of a metal, a resin, and a combination of a metal and a resin. Particularly, since the heat generated by the sheath heater or the like is conventionally high, the ice tray 102 has to be formed of metal. On the other hand, in this embodiment, since the ice-making heater 120 is formed to be thin, even if the temperature of the heat generated by the ice-making heater 120 is relatively low, the ice-tray 102 can be sufficiently freezed. Therefore, it is also possible to use a resin as a material constituting the ice tray 102.

The ejector 104 can serve to freeze the ice in the ice tray 102. The ejector 104 has an ejector shaft 104-1 connected to a motor 104-3 in the control box 108 and a plurality of ejector pins 104- 2). The ejector pin 104-2 can be rotated in a predetermined direction (for example, clockwise direction in FIG. 1) about the ejector shaft 104-1 so as to allow ice in the ice tray 102 to be released.

The ice-making heater 120 may be provided under the ice tray 102. At this time, the ice-making heater 120 may be provided in surface contact with the outer peripheral surface of the ice tray 102. The ice-making heater 120 may be provided along the longitudinal direction of the ice tray 102. The heating heater 120 can generate heat over a predetermined area. The moving heater 120 may be formed in a thin plate shape. For example, the thickness of the ice removing heater 120 may be greater than 0 and less than or equal to 1 mm. The lower limit of the thickness of the moving heater 120 may be appropriately set according to the material of the heating element and the insulating member constituting the moving heater 120 at the level of those skilled in the art. By making the ice-making heater 120 thin and reducing the heat capacity of the ice-making heater 120, the ice-making heater 120 can be quickly raised to a preset temperature. In this case, power consumption of the heating heater 120 can be reduced.
