Description

Technical Field

[0001] The present invention relates to the technical field of ice making, in particular to a novel ice making machine. Background Art

[0002] The existing air-cooled extrusion ice maker has a structural connection as follows Figure 6 As shown, the refrigeration system mainly comprises a reduction motor 7, a water tank body 701, a compressor body 702, a condenser body 703, an evaporator body 704, and a throttling device 705. The operation process of the refrigeration system is as follows: first, the low-temperature, low-pressure refrigerant gas is compressed into a high-temperature, high-pressure refrigerant gas by the compressor body 702. Then, the high-temperature, high-pressure refrigerant passes through the condenser body 703 to release heat, and the high-temperature, high-pressure refrigerant gas is condensed into a medium-temperature, high-pressure refrigerant liquid. After being throttled by the throttling device 705, the medium-temperature, high-pressure refrigerant liquid becomes a low-temperature, low-pressure refrigerant gas-liquid mixture. The low-temperature, low-pressure refrigerant gas-liquid mixture undergoes indirect heat exchange with water in the evaporator body 704, becoming a low-temperature, low-pressure refrigerant gas, which is then sucked back into the compressor body 702 and enters the next cycle. The water in the water tank body 701 undergoes indirect heat exchange with the refrigerant in the evaporator body 704, turning into ice. The reduction motor 7 drives the mechanical components inside the evaporator body 704 to squeeze out the ice.

[0003] Conventional squeeze ice machines have the following problems:

[0004] 1. Water quality issues;

[0005] The quality of the water source has a significant impact. When the hardness or TDS value of the water source is too high, the hardness of the ice will increase, making it difficult to squeeze the ice out of the evaporator. The amount of dissolved matter precipitated in the water will increase, causing dirt to form inside the evaporator, affecting the operation of the mechanical parts in the evaporator and the cleanliness of the ice, posing a food safety risk. For outdoor and some places, clean water sources are generally not available.

[0006] 2. High ambient temperature and water temperature issues;

[0007] Affected by the ambient temperature and water source temperature, when the ambient temperature and water source temperature are very high, the ice making performance of the ice maker will drop sharply, or even fail to make ice normally; ice makers using air-cooled condensers cannot effectively dissipate heat when the ambient temperature is very high, and ice makers using shell-and-tube water-cooled condensers have more complex systems or consume more water; therefore, in environments with high ambient temperature and high water temperature, conventional ice makers will have low ice making efficiency due to high water temperature. Air-cooled ice makers will have poor ice making efficiency or fail to operate normally due to high ambient temperature, and conventional shell-and-tube water-cooled ice makers will have large water waste or overly complex systems due to their high water demand;

[0008] Air-cooled condensers use air as the medium and have low heat exchange efficiency. When used in high-temperature environments, they need to be equipped with a large heat exchange area and air volume; shell-and-tube water-cooled condensers use water as the medium and use the sensible heat of water for heat exchange, with medium efficiency; if a closed circulating water system is used to fully utilize water, an additional cooling tower for water heat dissipation is required, and the structure is more complex; if an open water system is used, a larger water consumption is required; evaporative condensers use air and water as the medium and use the latent heat of water for heat exchange, with higher efficiency and a more compact structure.

[0009] 3. Cold water function problem

[0010] Conventional ice makers are only equipped with room temperature water and ice making functions, and do not have cold water function.

The two parts of the pipeline are independent of each other. The first monitoring sensor 615 is set at the connection with the cold water module 4, and is used to monitor the parameters of this condensation pipeline. The second monitoring sensor 627 is set at the connection with the ice-making module 5, and is used to monitor the parameters of this condensation pipeline. It can also be used to control the water spraying amount at the sprayer 614 and the speed of the exhaust fan 617, so as to maintain the stability of the heat dissipation of the refrigeration system.

[0064] In addition, the evaporative condenser 6 of the present invention is provided with aluminum fins, which are made of corrosion-resistant alloy fins and are treated with a hydrophilic coating on the surface to reduce the formation of large water droplets on the fin surface, affecting the heat exchange effect, and also avoiding corrosion of the fins caused by water residue. The fin spacing is larger than the design of a conventional air-cooled condenser to adapt to the flow and evaporation of water on the fin surface.

[0065] The fourth water pump 612 adjusts the amount of water sucked out from the water receiving tray 607, thereby controlling the amount of water sprayed out from the sprinkler 614. The water flow filter 613 is used to filter impurities in the water receiving tray 607 to prevent impurities from entering the fourth water pump 612 and the sprinkler 614 and causing blockage.

[0066] The water baffle 616 is composed of a corrugated stainless steel plate, which is used to intercept water droplets in the air flow and guide the water droplets to the water receiving tray 607 to achieve the purpose of saving water; the exhaust fan 617 is composed of a waterproof variable frequency fan, which is controlled by the second monitoring sensor 627 provided on the evaporative condenser 6 to adjust the speed and control the ventilation volume; the evaporative condenser 6 of the present invention is provided with fins on the heat exchange copper tube, and the control logic can determine whether water spraying is needed according to the heat dissipation requirement; when the heat dissipation requirement is low, it can be used as an air-cooled condenser to reduce water consumption.

[0067] Conventional air-cooled ice makers cannot meet the heat dissipation needs of outdoor or high-temperature places; conventional water-cooled ice makers consume a lot of water due to the use of a shell-and-tube water-cooled heat exchanger; conventional ice makers are generally not equipped with a water treatment part and can only be used in limited occasions; conventional ice makers have no cold water function and can only provide ice and room temperature water; the present invention mainly solves the use needs of outdoor or high-temperature places and can adapt to poor water quality; a new evaporative condenser 6 is used, which has a compact structure and low water consumption, achieving a heat dissipation effect; a cold water module 4 is provided to directly provide cold water to customers and improve the efficiency of the ice making module 5.
