Abstract

An icemaker includes an ice-making tray in which ice is produced, an ice-discharging mechanism that removes the ice from the ice-making tray, a driver that drives the ice-discharging mechanism and that is attached to the ice-making tray on a front side in a front-rear direction, and a lighting unit that emits light. The lighting unit emits the light toward a rear side in the front-rear direction.

Claims (29)

1. An icemaker that is disposable in a freezer, and, when power is supplied, that makes ice by using cold air of a freezing chamber to freeze water that has been poured into an ice-making tray and that discharges the ice, the icemaker comprising: an ice-making tray in which ice is produced; an ice-discharging mechanism that removes the ice from the ice-making tray; a driver that drives the ice-discharging mechanism and that is attached to the ice-making tray on a front side in a front-rear direction of the freezes; and a lighting unit that emits light; wherein the lighting unit emits the light toward a rear side in the front-rear direction.

2. The icemaker according to claim 1 , wherein a direction in which the light is emitted from the lighting unit is inclined with respect to the front-rear direction.

3. The icemaker according to claim 1 , wherein the lighting unit includes at least one light source and a circuit board to which the at least one light source is attached, and an attachment surface of the circuit board to which the at least one light source is attached faces the rear side.

4. The icemaker according to claim 3 , wherein the attachment surface is inclined with respect to a plane perpendicular to the front-rear direction.

5. The icemaker according to claim 3 , wherein

the at least one light source includes a plurality of light sources;

the plurality of light sources are disposed at intervals in a top-bottom direction perpendicular to the front-rear direction; and

the at least one light source is a light emitting diode.

6. The icemaker according to claim 1 , wherein

the lighting unit includes at least one light source and an optical member on which light emitted from the at least one light source is incident; and

the optical member emits the incident light in a direction toward the rear side in the front-rear direction.

7. The icemaker according to claim 6 , wherein the optical member includes at least a portion of a Fresnel lens.

8. The icemaker according to claim 6 , wherein

the lighting unit further includes a circuit board to which the at least one light source is attached; and

an attachment surface of the circuit board to which the at least one light source is attached is disposed along the front-rear direction.

9. The icemaker according to claim 1 , wherein the lighting unit is provided in the driver.

10. The icemaker according to claim 1 , wherein the lighting unit is provided on a side surface of the driver along the front-rear direction.

11. The icemaker according to claim 1 further comprising:

a sensor that detects an open/closed state of the freezer; wherein

the lighting unit emits light when the sensor detects that the freezer is in an open state.

12. A freezer comprising the icemaker according to claim 1 .

13. A freezer comprising:

a freezer body that is box-shaped and that includes an opening on a front side in a front-rear direction;

a door that opens and closes the opening; and

an icemaker attached to a side surface on one side in a left-right direction perpendicular to both the front-rear direction and a top-bottom direction among inner side surfaces of the freezer body; wherein

the icemaker includes an ice-making tray in which ice is produced, an ice-discharging mechanism that removes the ice from the ice-making tray, a driver that drives the ice-discharging mechanism and that is attached to the ice-making tray on the front side, and a lighting unit that emits light; wherein

the lighting unit includes a light source and a circuit board to which the light source is attached, and emits the light toward a rear side in the front-rear direction;

an attachment surface of the circuit board to which the light source is attached faces the rear side; and

when viewed in the top-bottom direction, an inclination of a first imaginary line with respect to the left-right direction, the first imaginary line connecting an end portion of the attachment surface on a first side in the left-right direction and an end portion of the opening on a second side in the left-right direction, is equal to or less than an inclination of a second imaginary line with respect to the left-right direction, the second imaginary line connecting the light source and the end portion of the opening on the second side in the left-right direction.
