As shown in fig. 1 to 4, an air bath automatic aseptic ice maker can include a cabinet 1, a refrigerator group, a cooling tank 3, and a stirring device 4. The chassis 1 is a rectangular parallelepiped structure and is mainly made of sheet metal (e.g., aluminum profile or steel). The upper part of the cabinet 1 is provided with a cold air chamber 11. The left and right sides of the casing at the lower part of the cabinet 1 are provided with heat radiating holes 12. The refrigerator unit is installed in the cabinet 1 and is in fluid communication with the cool air chamber 11, i.e., the refrigerator unit provides cool air to the cool air chamber 11. The cooling bath 3 is installed in the cooling-air chamber 11 and has a plurality of through-holes 31 on the bottom and side walls thereof. That is, the cooling bath "bathes" in cool air. In making ice, a disposable film (not shown) is laid in the cooling bath 3 and the upper end is sealed to the upper peripheral edge of the cooling bath 3 to form a container required for making ice. That is, the cooling bath 3 functions to support the disposable film. The cold air in the cold air chamber 11 exchanges heat with the sterile liquid (e.g., physiological saline) in the disposable film through the wall of the cooling bath 3 and the through holes 31, thereby achieving ice making. The stirring device 4 includes a driving mechanism 41, a push rod 42, and a stirring plate 43, wherein the driving mechanism 41 is disposed below the cold air chamber 11, the lower end of the push rod 42 is connected to the driving mechanism 41 through the bottom of the cold air chamber 11 and the upper end is connected to the stirring plate 43 through the bottom of the cooling bath 3. Therefore, the stirring plate 43 can reciprocate up and down to jack up and down the disposable film, so as to stir the physiological saline water, thereby accelerating the ice making speed and improving the uniformity of ice slush.

The cold air chamber 11 is surrounded by the heat insulation layer, thereby avoiding the heat exchange between the surrounding environment and the cold air chamber 11 and achieving the purpose of saving energy consumption. That is, each wall surface of the cooling air chamber is made of an insulating layer. Specifically, the insulating layer includes an insulating material 111 in the middle and a metal material 112 on both sides to ensure both an insulating effect and sufficient strength. The thickness of the heat insulating material 111 is usually 20 times or more the thickness of the metal material 112, and for example, the thickness of the heat insulating material is 5cm and the thickness of the metal material is 1.5mm. The heat insulating material may be polyurethane foam, heat insulating cotton, etc. The metal material may be an aluminum plate, a stainless steel plate, or the like.

The refrigeration unit may include a compressor 20, a condenser 21, an evaporator 22, and a fan 23. Wherein a compressor 20 and a condenser 21 are installed at a lower portion of the cabinet 1, and an evaporator 22 and a fan 23 are installed in the cooling air chamber 11. Specifically, the evaporator 22 is fixedly installed on the right sidewall of the cooling air chamber 11, and the fan 23 is fixedly installed on the evaporator 22. The fan 23 circulates the air in the cold air chamber past the fins of the evaporator 22 for cooling. The construction and connection of the compressor, condenser 21 and evaporator 22 are well known and will not be described in detail herein. Preferably, the fan 23 is an axial fan.

The cooling tank 3 has a cylindrical shape and may be made of stainless steel or the like. The diameter of the through-hole 31 of the cooling bath 3 is 1 to 3 cm, preferably 2 cm. The external air can enter the cooling air chamber 11 through the through-holes 31. When ice is made, the cold air in the cold air chamber 11 can contact the disposable film through the through holes 31, thereby cooling the physiological saline in the disposable film.

The upper end of the cooling channel 3 has a flange 32 so that the cooling channel 3 can be suspended in the top opening of the cooling air chamber 11 to facilitate access to the cooling channel 3. The outer wall of the cooling tank 3 near the upper end (i.e., the flange 32) is provided with a ring-shaped clamping groove 33 to facilitate fixing of the disposable film. Specifically, when ice is made, the disposable film is sleeved on the ring-shaped clamping groove 33, and then the disposable film binding opening is fixed in the ring-shaped clamping groove 33 by using a rubber band or a rope.

As shown in fig. 3 and 4, the driving mechanism 41 includes a motor 411 and a crank link mechanism, the motor 411 is fixed on a motor base 414, and the motor base 414 includes an L-shaped main body and two reinforcing angle plates fixed at the corners of the L-shaped main body. The output shaft of the motor 411 is mounted on the L-shaped body by a bearing. One end of the crank link mechanism is connected to an output shaft of the motor 411, and the other end is connected to a lower end of the push rod 42, so that the agitating disk 43 can reciprocate up and down. Specifically, the crank link mechanism includes a first link 412 and a second link 413, one end of the first link 412 is fixed to an output shaft of the motor 411, the other end is hinged to one end of the second link 413, and the other end of the second link 413 is hinged to a lower end of the push rod 42. Specifically, both ends of the second link 413 are hinged with the first link 412 and the push rod 42 through respective joint bearings. The rotation of the motor 411 is converted into the up-and-down movement of the push rod 42 by the crank link mechanism. It should be understood that the drive mechanism 41 is not limited to the illustrated embodiment. In order to prevent the push rod 42 from wobbling, the push rod 42 is sleeved with at least one linear bearing 44. In the present embodiment, the linear bearing 44 is embedded on the bottom of the cooling air chamber 411.

The stirring plate 43 is detachably and fixedly installed at the upper end of the push rod 42 so as to facilitate replacement of different stirring plates. Specifically, a screw is fixedly arranged on the lower surface of the stirring disc 43, and a screw hole is formed at the upper end of the push rod 42. The stirring plate 43 is fixed to the upper end of the push rod 42 by screwing a screw into the screw hole. In the present embodiment, the stirring plate 43 is circular. It should be understood that the stir plate can be other shapes as well. The agitating plate 43 may be made of stainless steel or the like. The agitating plate 43 needs to have a relatively large area to provide a sufficient supporting area to ensure the agitating effect. Preferably, the diameter of the stirring plate 43 is 0.5 to 0.8 of the diameter of the cooling tank.

To facilitate movement, the bottom of the cabinet 1 may be mounted with rollers (not shown). Preferably, the roller is a universal roller with a braking function.
