Description

technical field [0001] The invention relates to a water circulation mechanism of an ice maker, which is arranged on the ice maker and is used to make the water in the ice making water box of the ice maker flow during the ice making process so as to obtain crystal clear ice cubes. Ice machine technical field. Background technique [0002] While ice machines are becoming more and more popular, people's corresponding technical requirements for ice machines are also becoming stricter. For example, in order to make ice machines produce high-quality transparent ice cubes with extreme transparency, the industry's The water circulation mechanism is unremittingly committed to improvement, because only by maintaining the reasonable movement (flow) of the water in the ice making water box of the ice maker during the ice making process can transparent ice be obtained. And because the indisputable fact is: the transparency of ice cubes is low, which means that there is more air in the i...

Problems solved by technology

Although this structure is considered to be a good structure for producing transparent ice, it has the disadvantages of taking care of one thing and sacrificing the other. The specific performance is: (A) The pressure of the water pump is too high, which has a high requirement on the life of the water pump and increases the cost of components. ; (B) the nozzles are easy to block, especially when using some hard water; (C) waste of time and energy consumption, because the water is sprayed upwards in the form of mist during the spraying process, when the mist flow and air are forced to After sufficient heat exchange, the cooling of circulating water becomes very uneconomical, especially when the ambient temperature is high, the amount of ice production will drop sharply, which is not suitable for the environment of energy saving and climate warming in the modern era; (D) in deicing During the process, since the opening of the ice mold is facing downward, and the water flow is sprayed from the bottom to the opening of the ice mold, so to make the ice cubes fall from the ice mold, several holes must be opened on the top of each ice mold. The small hole is used as a ventilation hole for air pressure balance inside and outside the ice mold during deicing. Otherwise, the ice mold will be in a negative pressure state during deicing, and the ice cubes will not fall off in a short time. In order to make the ice cubes fall off as soon as possible, it is necessary to Add an appropriate amount of normal temperature water to the top and back of the mold to help de-ice, and the top and back of the ice mold will accumulate dust, dirt, sundries, etc. after a period of use, and some have even been corroded due to the quality of the evaporator's own coating. , so that the normal temperature water that helps deicing flows through the very unhygienic surface, and then flows into the ice mold through the small holes on the top of each ice mold mentioned above, and then the ice cubes are taken off after contacting the ice cubes. In this way, every ice-making cycle will have a part of polluted water to be brought into the ice-making water on the surface of the ice cube of this mold and the ice-making water of the lower mold. Progressive recognition of defects and unwelcome

[0005] 2. The dripping water circulation mechanism, the ice cubes made in this way will not be very transparent, and the ice cubes must be bonded together in the ice mold to be deiced as a whole. The potential energy collides with the storage bin to separate the ice cubes, so the ice cubes are irregular. The ice-making process is as follows: the circulating water is distributed into several small streams through a water distributor from a high place, and along the basic The surface of the vertically installed concave ice mold flows, so that under the influence of gravity, the water flow will gradually form ice against the concave ice mold. Since the cold energy on the ice mold is transferred to it by the evaporator attached to it, In addition, a large amount of water flow is constantly exchanged with air, so its efficiency is low. Compared with products with the same ice production capacity, it shows the disadvantage of relatively high power.

However, the movement of this mechanism will make the water surface of the ice-making water box uneven, so that the surface of the ice cubes produced will be uneven, which will greatly affect the quality of the ice cubes; The distribution density of the popsicle sticks is reduced, and because about one-third of the rotation circumference of the water stirring rod participates in stirring the water, and the rest is exposed outside, the cooled water in the ice making water box and the water surface will be separated. The air in the water is exchanged through the rotation of the water stirring rod, which reduces the cooling efficiency and increases the energy consumption of the ice machine. In addition, the water stirring mechanism can only use a very low rotation speed, generally 30-80RPM, so that the ice making The water in the box has poor fluidity, so it is not possible to make clear ice cubes

This kind of mechanism is obviously limited to the agitation speed of water. When the speed reaches 100 rpm, the water will be taken out of the ice making water box, making the water level in the ice making water box shallower and shallower, so it cannot achieve both energy saving and energy saving. Efficient and transparent high quality transparent ice making system

[0007] 4. Water circulation mechanism - this is another way to make transparent ice cubes. It is a kind of active device that does not use auxiliary equipment in the ice making water box, and the production is realized by the continuous self-circulation of the water itself in the water box. Transparent ice cubes, this method is relatively energy-saving, but the defects of this water circulation mechanism are: there are movable (moving) parts in the waterway connection, and there is relative rotation or frictional movement, so the adjustment accuracy of the mechanism is high, and Affect the service life

As described in Chinese Patent No. 02263082.1, a water circulation stirring mechanism of an ice maker uses a water pump through a hose and a rotating connection with three silicone rings to seal the ice making water box. At the end of the ice-making cycle, in order to remove the ice cubes, the ice-making water box must be turned over, so the connection needs to be rotated relatively. The reliability, lifespan, and silicone ring of the rotating mechanism will be worn due to long-term rotation. There will be water leakage and the water level will drop. If the water level in the ice making water box drops, the water pump will run idly, and the water pump will be damaged soon.
