A milling device has a milling pole with a helical ridge extending into the ice barrel and driven by a motor to rotate. A feeding member is provided beside the milling device. When the ice barrel is cooled by the refrigerating device to −10° C. and below, liquid is poured into the ice barrel by the feeding member and frozen. Then, the milling device is actuated and the ice is removed and powdered by the helical ridge, and pushed downwards to fall into a container under the ice barrel.
Description
- 1. Field of the Invention
- The present invention relates to an ice machine, and more particularly to an automatic powdered ice machine.
- 2. Description of Related Art
- For producing ice food for sale, a conventional ice machine is provided with an ice pot. A refrigerating means is provided under the ice pot to cool the pot bottom to −10° C. and below. Liquid or drink (such as milk, juice) is poured into the pot and frozen almost instantly. An ice-producer stirs the ice in the ice pot by means of a scoop, and the ice becomes powdered and as fine as snow flakes.
- However, it is very inconvenient for the ice-producer to produce the powdered ice by continuously stirring. If there are lots of customers, he should stir the ice in the pot and scoop up the powdered ice at the same time and will feel embarrassed at keeping customers waiting. Moreover, if the ice-producer stops stirring the ice for a certain time, there will be ice lumps frozen on the pot, and it is very difficult to remove these thick ice lumps, in addition to the powdered ice having a coarse grain without a good taste. Therefore, in general, two staff members are required to produce good powdered ice in an appropriate time but this results in high labor cost in a business that is low profit. Furthermore, the ice pot has a large size, and can not be used conveniently in a house if a person wants to produce the ice at home.
- Therefore, the invention provides an automatic powdered ice machine to mitigate or obviate the aforementioned problems.
- The main objective of the present invention is to provide an ice machine which is operated automatically to produce powdered ice and has a small size.
- Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

An ear (not numbered) is formed at an outer periphery of ice barrel (10) and an inlet (13) is defined in the ear and in communication with the counterbore (12) and the ice barrel (10).
- The refrigerating devices (20) are respectively provided at two opposed sides of the ice barrel (10), and each have a semiconductor refrigerating component (21) with a cold surface abutting the outer periphery of the ice barrel (10). A heat sink (22) with multiple fins (not numbered) abuts a hot surface of the semiconductor refrigerating component (21), and a fan (23) is provided at a side of the heat sink (22) opposite to the semiconductor refrigerating component (21). The outer periphery between the two refrigerating devices (20) is covered with a layer of heat insulating material (14) to prevent the ice barrel (10) from exchanging heat with the external environment.
- The milling device (30) has a milling pole (35) extending into the ice barrel (10) and driven by a motor (31) provided above the ice barrel (10). The motor (31) has an output axle extending downwards and a driving gear (32) mounted on the output axle.

- The feeding member (40) has a funnel (41). A pipe (42) connected with the funnel (41) has an outlet (not numbered) in alignment with the inlet (13) of the ear. A control valve (43) is provided between the funnel (41) and the pipe (42). A passage (431) is defined through the control valve (43) and in communication with the funnel (41) and the pipe (42). A knob (432) is mounted at an outer periphery of the control valve (43) and can be turned to control a flux through the passage (431) into the pipe (42) from the funnel (41). The control valve (43) is a conventional element, which should be known by those skilled in the art, so its structure will not be described in detail further.
- In use, the semiconductor refrigerating components (21) are actuated to lower the temperature of the ice barrel (10) to −10° C. and below by the cold surfaces. Heat from the hot surfaces can be discharged by the heat sinks (22) and the fans (23). Afterwards, the motor (31) is actuated to drive the milling pole (35) to turn, while liquid is poured into the funnel (41), and flows through the passage (431) of the control valve (43) and the pipe (42) and into the counterbore (12) via the inlet (13).
