Automatic icemaker
An automatic icemaker of the present invention includes a control box, an ice-making tray supporting frame rotatably supported and rotated by the control box, at least one ice-making tray rotatably supported by the ice-making tray supporting frame, a rotation limiter fixed to the ice-making tray supporting frame and limiting the rotation of the ice-making tray, a stopper fixed to the control box, and a projection provided to the ice-making tray. Irregularities are provided to at least one of the contact surfaces of the stopper and projection.
1. An automatic icemaker comprising:
a control box;
an ice-making tray supporting frame rotatably supported and rotated by said control box;
at least one ice-making tray rotatably supported by said ice-making tray supporting frame;
a rotation limiter fixed to said ice-making tray supporting frame, and limiting rotation of said ice-making tray with respect to the ice-making tray supporting frame;
a stopper fixed to said control box, a contact surface of said stopper being provided with irregularities; and
a projection integrally mounted to said ice-making tray.
2. The automatic icemaker of claim 1 , wherein said at least one ice-making tray comprises two ice-making trays supported by said ice-making tray supporting frame.
3. The automatic icemaker of claim 1 , wherein a contact surface of said projection is provided with a protrusion.
4. The automatic icemaker of claim 1 , wherein said projection directly engages with said contact surface of said stopper.
5. The automatic icemaker of claim 1 , said at least one ice-making tray is twisted for discharging ice cubes when said projection directly engages with said contact surface of said stopper.
6. The automatic icemaker of claim 1 , wherein said automatic icemaker comprises two ice-making trays arranged back to back.
7. The automatic icemaker of claim 6 , wherein said two ice-making trays are twisted for discharging ice cubes in turn.
8. The automatic icemaker of claim 1 , wherein said projection directly engages with said contact surface of said stopper so that said at least one ice-making tray is vibrated and twisted for discharging ice cubes.
9. The automatic icemaker of claim 1 , wherein an engagement of the rotation limiter and said at least one ice-making tray and an engagement of the projection and the contact surface of said stopper are respectively arranged in two opposite sides of the said at least one ice-making tray so that said at least one ice-making tray is vibrated and twisted for discharging ice cubes.
10. An automatic icemaker comprising:
a control box;
an ice-making tray supporting frame rotatably supported and rotated by said control box;
at least one ice-making tray rotatably supported by said ice-making tray supporting frame;
a rotation limiter fixed to said ice-making tray supporting frame, and limiting rotation of said ice-making tray with respect to the ice-making tray supporting frame;
a stopper fixed to said control box; and
a projection integrally mounted to said ice-making tray, a contact surface of said projection being provided with irregularities.
11. The automatic icemaker of claim 10 , wherein said at least one ice-making tray comprises two ice-making trays supported by said ice-making tray supporting frame.
12. The automatic icemaker of claim 10 , wherein a contact surface of said stopper is provided with a protrusion.
13. The automatic icemaker of claim 10 , wherein said stopper directly engages with said contact surface of said projection.
14. The automatic icemaker of claim 10 , said at least one ice-making tray is twisted for discharging ice cubes when said stopper directly engages with said contact surface of said projection.
15. The automatic icemaker of claim 10 , wherein said automatic icemaker comprises two ice-making trays arranged back to back.
16. The automatic icemaker of claim 15 , wherein said two ice-making trays are twisted for discharging ice cubes in turn.
17. The automatic icemaker of claim 10 , wherein said projection directly engages with said contact surface of said stopper so that said at least one ice-making tray is vibrated and twisted for discharging ice cubes.
18. The automatic icemaker of claim 10 , wherein an engagement of the rotation limiter and said at least one ice-making tray and an engagement of the projection and the contact surface of said stopper are respectively arranged in two opposite sides of the said at least one ice-making tray so that said at least one ice-making tray is vibrated and twisted for discharging ice cubes.
