Description
- This application is based on and claims priority to Korean Patent Application No. 10-2015-0085880, filed on Jun. 17, 2015, the disclosure of which is incorporated herein in its entirety by reference.
- Embodiments according to the present invention relate to an ice maker for a refrigerator and an assembly method thereof, and more particularly to an ice maker which can automatically make and store ice.
- A refrigerator is a device for low temperature storage of food and may be configured to provide freezing storage or cold storage of food according to the kind of food that a user wants to store.
- The inside of the refrigerator is cooled by continuously supplied cold air, in which the cold air is continuously generated by heat exchange with a refrigerant according to a cooling/freezing cycle that includes processes of compression, condensation, expansion, and evaporation. The cold air supplied to the inside of the refrigerator is evenly transferred to the inside of the refrigerator by convection to store food in the refrigerator at a desired temperature.
- Generally, the main body of the refrigerator has a rectangular parallelepiped shape of which the front surface is open. The inside of the main body may be provided with a refrigerating compartment and a freezing compartment. Further, the front surface of the main body may be provided with a refrigerating compartment door and a freezing compartment door, and a storage space in the refrigerator may be provided with multiple drawers, shelves, receiving boxes, etc., in which various foods may be stored in an optimal condition.
- Traditionally, a top mount type of refrigerator, in which a freezing compartment is positioned at an upper portion and a refrigerating compartment is positioned at a lower portion, has been mainly used. Recently, however, for user convenience, a bottom freezer type of refrigerator, in which the freezing compartment is positioned at a lower portion, has been introduced. In the case of the bottom freezer type of refrigerator, the more frequently used refrigerating compartment is positioned at an upper portion and the relatively less frequently used freezing compartment is positioned at a lower position, and thus a user may conveniently use the refrigerating compartment. However, since the freezing compartment is positioned at the lower portion, the bottom freezer type of refrigerator has a problem because a user has to bend his/her back to open the freezing compartment door and take out items such as ice.
- To solve the above problem, a refrigerator in which an ice dispenser is installed at or in the refrigerating compartment door positioned at the upper portion of the bottom freezer type of refrigerator has recently been introduced. In this case, an ice machine that generates ice may be provided on the inside of the refrigerating compartment door or inside the refrigerating compartment itself.
- The ice machine may include an ice maker that has an ice tray for generating ice, an ice bucket in which the ice is stored, and a transfer assembly for transferring the ice stored in the ice bucket to the dispenser.
- A conventional ice machine further includes an ice removing heater for applying heat to the ice tray so that the ice can be easily separated from the ice tray. The ice removing heater is generally installed and affixed to a bottom surface of the ice tray. In order to affix the ice removing heater to the ice tray, the conventional ice machine uses caulking with the ice tray and/or an additional affixing member.
- However, the conventional ice machine has a problem because the heater may separate from the ice tray due to omission of the caulking or some other weakness, which can cause an accident, such as a fire, to occur.
- Further, in the case where separate components, such as a rivet, are used to affix the ice removing heater, the heater may be damaged by rust due to corrosion of the rivet. Also, damage such as distortion of the heater may occur in the process of installing the separate components. These types of problems may increase material costs, decrease productivity, and interfere, with the cold air flow path.
- In view of the above, the present invention provides an ice maker for a refrigerator and an assembly method thereof, which enable a heater to be firmly and easily affixed to an ice tray by providing an attachment portion that projects outwardly from one end of the ice tray.
- In accordance with an aspect of the present invention, a method for assembling an ice maker for a refrigerator includes: receiving an ice tray having a seat portion and an attaching portion, receiving a heater to which an elastic attaching member is attached, temporarily affixing (placing) one end of the heater against the seat portion of the ice tray, moving the heater so that, the heater and the fixing portion come into contact with each other, and rotating the heater so that the elastic attaching member of the heater comes into contact with the ice tray.
- In accordance with another aspect of the present invention, an ice maker for a refrigerator includes: an ice tray configured to generate ice, a heater configured to apply heat to the ice tray so that the ice is separated from the ice tray, a seat portion formed on the ice tray to support the heater, and a heater attaching portion configured to project from a part of the ice tray.

Referring toFIG. 5B , which is a cross-sectional view ofFIG. 5A , as a result of moving and rotating theice removing heater 205, one end of theice removing heater 205 comes in contact with the surface(s) of the heater attaching portion 245 (e.g., one end of theice removing heater 205—specifically, the bottom of the shapedice removing heater 205—is inserted into and up against the heater attaching portion 245). Thus, theice removing heater 245 can be stably affixed between theheater attaching portion 245 and the bottom surface of theice tray 210. Accordingly, theice removing heater 205 can be held in place against the bottom surface of theice tray 210, so that theice removing heater 205 can be prevented from moving in a direction that is perpendicular to the bottom surface of theice tray 210, in upper/lower ('vertical) direction (e.g., the z-direction). In an embodiment, caulking is included between theice removing heater 205 and theheater attaching portion 245. - Further, as illustrated in
FIG. 5A , once, the movement of theice tray 210 of theice removing heater 205 is completed and theice removing heater 205 is in place, the elastic attachingmember 246 of the one end of theice removing heater 205 comes in contact with the side surface of theice tray 210, and thus theice removing heater 205 can be prevented from moving again, in the length direction (e.g., the x-direction) of theice tray 210. - Preferring to
FIGS. 6A and 6B , when the position adjustment (placement) of theice removing heater 205 and theice tray 210 is completed, the drivingportion 230 is provided for theice tray 210 to which theice removing heater 205 is attached, and thus assembly of theice maker 200 can be completed. According to an embodiment of the present invention, the drivingportion 230 may have an opening (not illustrated) through which the one end of theice removing heater 205 can pass (can be inserted), and the drivingportion 230 may be affixed together with theice tray 210 using additional affixing members (e.g., a screw and bolt). Because the drivingportion 230 is additionally provided to theice tray 210 to which theice removing heater 205 is attached, theice removing heater 205 can be attached to theice tray 210 more firmly and stably. - Hereinafter, operations and effects of the
ice maker 200 and theice tray 210 according to an embodiment, of the present invention will be described. - The cooling portion (not illustrated) of the
