Abstract
An ice making machine may include an ice tray having a plurality of recessed parts and a cold air duct having a cold air inflow port connected with a cold air supply port and one cold air outlet port facing the ice tray on an upper side. A size of the cold air outlet port is smaller than a size of an ice making face of the ice tray having a contour which includes the plurality of the ice making recessed parts along edges of openings of the plurality of the ice making recessed parts, and the cold air outlet port faces a center portion of the ice making face. It is preferable that an opening area of the cold air outlet port is 50% or less of an area of the ice making face and/or is smaller than an opening area of the cold air inflow port.
Claims17
An ice making machine which is disposed in an ice making chamber provided with a cold air supply port to which cold air is supplied, the ice making machine comprising:
- an ice tray comprising a plurality of ice making recessed parts;
- and
- a cold air duct comprising a cold air inflow port connected with the cold air supply port and one cold air outlet port which faces the ice tray on an upper side with respect to the ice tray;
- wherein a size of the cold air outlet port is smaller than a size of an ice making face of the ice tray having a contour which includes the plurality of the ice making recessed parts along edges of openings of the plurality of the ice making recessed parts;
- wherein the cold air outlet port faces a center portion of the ice making face;
- wherein an opening area of the cold air outlet port is 50% or less of an area of the ice making face;
- wherein an inner wall face of a downstream end portion of the cold air duct comprises a first guide face structured to guide cold air flowing out from the cold air outlet port toward the ice tray in a direction perpendicular to the ice making face;
- wherein the first guide face is extended in an upper and lower direction,
- wherein the cold air duct comprises a second guide face structured to guide the cold air to the first guide face at a position adjacent to the first guide face on an upstream side in a flowing direction of the cold air, and
- wherein the second guide face is curved toward the first guide face and is continuously connected with an upper end edge of the first guide face.
An ice making machine which is disposed in an ice making chamber provided with a cold air supply port to which cold air is supplied, the ice making machine comprising:
- an ice tray comprising a plurality of ice making recessed parts;
- a cold air duct comprising a cold air inflow port connected with the cold air supply port and one cold air outlet port which faces the ice tray on an upper side with respect to the ice tray;
- a drive unit which is provided at a first end in a longitudinal direction of the ice tray and is structured to turn the ice tray;
- and
- a frame body which supports the ice tray and the drive unit;
- wherein a size of the cold air outlet port is smaller than a size of an ice making face of the ice tray having a contour which includes the plurality of the ice making recessed parts along edges of openings of the plurality of the ice making recessed parts;
- wherein the cold air outlet faces a center portion of the ice making face;
- wherein the ice tray is located on an inner side of the frame body,
- wherein the cold air duct comprises:
- an intermediate duct portion provided in a frame body portion of the frame body, the intermediate duct portion extending in the longitudinal direction;
- an upstream side duct portion which comprises the cold air inflow port and is communicated with the intermediate duct portion;
- and
- a downstream side duct portion which comprises the cold air outlet port and is communicated with the intermediate duct portion, and
- wherein the downstream side duct portion is extended to an upper side with respect to the frame body from a middle position in the longitudinal direction of the frame body portion.
