Water stirring mechanism for ice-making machine

Abstract

This invention is a kind of water stirring mechanism of ice machine. It is improvement of water stirring mechanism of existing ice machine. It includes: at least one water stirring electric engines, at least one electric engine gallows frames and at least one water stirring mechanisms. The said electric engine gallows frames extend and connects above the icebox of ice machine. Water stirring electric engine is arranges on the electric gallows frame. The electric engine shaft of water stirring electric engine extends to the close bottom of icebox. The said water stirring mechanism is fixed on the shaft end of the said close bottom. The water stirring mechanism is working by rotating. Thus, it controls the occupied areas of the icebox. The water stirring mechanism is totally immerged in the bottom of the icebox. Thus, it prevents heat exchange between the refrigerated water in the icebox and the area above water, which conserves energy. Water is stirred by rotation mode, which improves the fluidity of water. It increases the transparency of ice.

Description

technical field [0001] The invention relates to a water stirring mechanism of an ice maker, which is an improvement on the water stirring mechanism of the ice maker in the prior art. Background technique [0002] In the existing bullet type ice maker, its structure mainly includes an ice making mechanism and a storage bin. The ice-making mechanism includes an ice-making box and an ice-making evaporator. The ice-making evaporator is fixed on the top of the ice-making box through a fixing device. Several icicles are connected to the evaporation pipe of the ice-making evaporator. One end of the several icicles extends downwards into the ice-making box. The evaporator is connected to the refrigeration In the system, the water in the ice box is refrigerated by the evaporator under the action of the refrigeration system, and freezes around the ice column. The freezing time is controlled by the controller. Once the freezing time is up or the size of the ice reaches the specified ...

Problems solved by technology

However, the movement of this mechanism will make the water surface of the ice making 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 rotating circle of the water stirring rod participates in stirring the water, and the rest is exposed outside, the cooled water in the ice making box and the air on the water surface will be separated. Heat exchange occurs through the rotation of the water stirring rod, which reduces the cooling efficiency and increases the energy consumption of the ice machine. The water stirring mechanism can only use a very low rotation speed, generally 40-80RPM, so that the water in the ice box The fluidity is very poor, so it is not possible to make ice cubes with high transparency

This kind of mechanism is obviously limited to the stirring speed of water. When the speed reaches 100 rpm, the water will be taken out of the ice making box, making the water level in the ice making box more and more shallow, so it is impossible to achieve both energy saving and Efficient and transparent transparent ice making system

Also as the water circulation stirring mechanism of an ice machine described in Chinese Patent No. 02263082.1, this mechanism adopts a rotary connection method in which a water pump passes through a hose and the ice making box is sealed with three silicone rings. At the end of each ice-making cycle, in order to remove the ice cubes, the ice-making box must be turned over, so the connection needs to be rotated relatively. There will be water leakage and the water level will drop. If the water level in the ice box drops, the water pump will run idly, and the water pump will be damaged soon. In order to protect the water pump, it is necessary to install a filter at the suction port of the pump. If there are sundries, Will accumulate at the screen, reducing the circulation of the water pump, thus affecting the transparency of the ice

Another example is the Chinese Patent No. 01238329.5, which describes a water stirring mechanism for an ice maker, which uses a link-type transmission device to convert circular motion into a horizontal push, and puts several finger-shaped drag bars on the ice-making machine of the ice box. The back and forth movement between the columns takes up more space in the ice making box and will cause wear of the plastic parts and pollute the water quality involved in ice making. The speed of rotation is limited. If it is too fast, the push rod will break and the water surface will be uneven. It is too slow to meet the requirements of transparent ice, and the speed can only be below 100RPM. Its transmission mechanism is complicated to install and requires high precision, so its practicality is not high. So far, no one has adopted this structure to mass-produce products.

[0005] In addition, if a dripping ice-making mechanism is used, transparent ice can also be produced, and the water is distributed from a high place through a water channel distributor into several small streams, which are distributed along the concave ice mold installed basically vertically. The surface is flowing, so that the water flow will gradually form ice against the concave ice mold under the influence of gravity, because the cold energy on the ice mold is transferred to it by the evaporator attached to it, plus the water flow and air in large quantities It is constantly exchanged, so its efficiency is very low, and the ice cubes are more irregular. Compared with products with the same ice production capacity, it shows the disadvantage of relatively high power, and the distance from the contemporary awareness of energy conservation and environmental protection is getting farther and farther.

[0006] There is also a spray structure, which can also produce transparent ice cubes. However, due to the high pressure of the water pump, the life of the water pump is very high, and the nozzle is easy to block. During the spraying process, the water is almost atomized and sprayed upwards. A lot of energy and air exchange are wasted, especially when the ambient temperature is high, the ice production will drop sharply. There is also a fatal weakness of the spray ice machine, which is its deicing process. Due to the opening of the ice mold It is facing downward, and the water flow is sprayed from bottom to top to the opening of the ice mold, so to make the ice fall from the ice mold, several small holes must be opened on the top of each ice mold to serve as the ice mold during the deicing process. Ventilation hole with internal and external air pressure balance, otherwise the ice mold will be in a negative pressure state when deicing, and the ice cubes will not fall off in a short time. In order to make the ice cubes fall off quickly, it is necessary to add an appropriate amount of normal temperature to the top of the ice mold Water is used to help de-icing, and the top of the ice mold has accumulated dust, dirt, debris and even the evaporator due to the quality of its own coating, and has been corroded, and the water to help de-icing comes from this, which is very unsanitary The surface of each ice mold flows through, and then flows into the ice mold through a number of pores on the top of each ice mold mentioned above, and the ice is removed after contact with the ice cubes. There is some water that may be polluted in each ice-making cycle. Obviously, if there is no better improvement, this type of product will become unpopular as consumers gradually understand this defect.
