Description

[Technical Field]

[0001] The present invention relates to the technical field of ice making machines, and more particularly to an ice making machine for bullet-shaped ice with improved clarity. [Background technology]

[0002] Bullet ice makers are used to produce bullet-shaped ice blocks for cold drinks. The evaporator molds are inserted into the ice-making tank during ice making, so the tank must be filled with enough water to submerge the molds. Because the water in the tank does not flow and contains air, the resulting ice blocks are white and opaque, with low density, rapid melting, poor transparency, and poor aesthetics.

[0003] To solve this problem, water from the water storage tank is continuously pumped into the ice-making tank via a circulating water pump, which allows the water in the ice-making tank to flow smoothly, reducing air bubbles and improving the clarity of the bullet-shaped ice. However, the water in the water storage tank is at room temperature, and the volume of water in the water storage tank is much greater than the volume of water in the ice-making tank. This creates a water circulation between the water storage tank and the ice-making tank. When the water from the water storage tank enters the ice-making tank during ice making, the water in the ice-making tank is heated, slowing down the ice-making speed. This requires improvement. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide an ice maker for bullet-shaped ice that improves the transparency of bullet-shaped ice, reduces the amount of circulating water used, increases the ice-making speed, improves the cleanliness of bullet-shaped ice, and improves the clarity of bullet-shaped ice.

[0005] To achieve the above object, the present invention employs the following technical means: An ice maker for making bullet-shaped ice with improved clarity includes a housing, within which are disposed an evaporator, a compressor, a condenser, an ice-making water tank, a water storage tank, and a water injection pump, a plurality of bullet-shaped ice molds are disposed below the evaporator, the bullet-shaped ice molds are inserted into the ice-making water tank, the water storage tank and the ice-making water tank are connected via a water injection pipe, a water injection pump is disposed on the water injection pipe, and a circulating ice-making mechanism is disposed within the housing, the circulating ice-making mechanism includes a circulating water tank, a circulating water pipe, and a circulating water pump, the circulating water tank is disposed below the ice-making water tank, the top of the circulating water tank is open, the vertical projection of the ice-making water tank is within the opening of the circulating water tank, the circulating water pipe is connected between the circulating water tank and the ice-making water tank, and the circulating water pump is disposed on the circulating water pipe.

[0006] Compared with the prior art, the present invention has the following advantages. During ice making, the water injection pump pumps water from the water storage tank into the ice-making tank. When the water in the ice-making tank overflows into the circulating water tank, the water injection pump is stopped and the circulating water pump is started, which pumps the water from the circulating water tank into the ice-making tank. The water from the ice-making tank continuously overflows into the circulating water tank, creating a circulation system, suppressing the generation of air bubbles and improving the clarity of the bullet-shaped ice. When filling the water tank, only the amount of water required to operate the circulating water pump needs to be pumped into the circulating water tank, reducing the amount of circulating water used and improving the ice-making speed. Filtering the circulating water with a filter plate improves the cleanliness of the bullet-shaped ice. [Brief explanation of the drawings]

[0008] As shown in Figs. 1 to 5, the ice maker for making bullet-shaped ice with improved transparency has a housing 1, in which an evaporator 21, a compressor 23, a condenser 22, an ice-making water tank 31, a water storage tank 4, and a water injection pump 5 are provided. A plurality of bullet-shaped ice molds 24 are provided below the evaporator 21, and the bullet-shaped ice molds 24 are inserted into the ice-making water tank 31. The water storage tank 4 and the ice-making water tank 31 are connected via a water injection pipe 51, and the water injection pump 5 is provided in the water injection pipe 51. A circulating ice-making mechanism is provided within housing 1, and the circulating ice-making mechanism includes circulating water tank 6, circulating water pipe 71, and circulating water pump 7. Circulating water tank 6 is provided below ice-making water tank 31, the top of circulating water tank 6 is open, and the vertical projection of ice-making water tank 7 is within the opening of circulating water tank 6. Circulating water pipe 71 is connected between circulating water tank 6 and ice-making water tank 31, and circulating water pump 7 is provided in circulating water pipe 71.

[0009] Conventional bullet-shaped ice makers produce poorly transparent bullet-shaped ice. When water from water storage tank 4 is pumped into ice-making water tank 31 to form a circulation system, a large amount of circulating water is required, slowing the ice-making speed. In contrast, in the present invention, during ice-making, water injection pump 5 pumps water from water storage tank 4 into ice-making water tank 31. When the water in ice-making water tank 31 overflows into circulating water tank 6, water injection pump 5 is stopped and circulating water pump 7 is started. This pumps the water from circulating water tank 6 into ice-making water tank 31. The water from ice-making water tank 31 continuously overflows into circulating water tank 6, forming a circulation system that suppresses the generation of air bubbles and improves the clarity of the bullet-shaped ice. When filling water, only the amount of water required to operate circulating water pump 7 needs to be pumped into circulating water tank 6, reducing the amount of circulating water used and improving the ice-making speed.

[0010] A circulation water supply port 66 and a water inlet port 67 are provided on the left and right sides of ice-making water tank 31, a filter plate 62 is provided inside circulating water tank 6, a circulation water outlet is provided at the bottom of circulating water tank 6, one end of circulating water pipe 71 is connected to the circulation water outlet and the other end is connected to circulation water supply port 66, a water inlet is provided at the bottom of water storage tank 4, one end of water inlet pipe 51 is connected to the water inlet and the other end is connected to water inlet 67. Filtering the circulating water with filter plate 62 improves the cleanliness of the bullet-shaped ice and prevents impurities and ice blocks from getting into circulating water pump 7, improving reliability and stability.

[0011] A downward-protruding circulating filter tank 61 is provided at the bottom of the circulating water tank 6. A filter plate 62 covers the top of the circulating filter tank 61, and a circulation outlet is provided at the bottom of the circulating filter tank 61. The water injection pump 5 pumps water from the water storage tank 4 into the ice-making water tank 31. When the water in the ice-making water tank 31 overflows into the circulating water tank 6, the water in the circulating water tank 6 passes through the filter plate 62 and flows into the circulating filter tank 61, and the water injection pump 5 quantitatively injects water. The quantitative amount of water injected by the water injection pump 5 is equal to the sum of the volumes of the ice-making water tanks 31 but less than the sum of the volumes of the circulating filter tanks 61. Alternatively, a water level sensor is provided above the circulating filter tank 61, and when the water level sensor detects the water level, the operation of the water injection pump 5 is stopped, thereby controlling the amount of circulating water used. When ice making is stopped, the water level in the circulating water tank 6 is within the circulating filter tank 61 and is below the filter plate 62, preventing mosquito breeding and improving cleanliness.

[0012] A plurality of connecting water tanks 63 are spaced apart on the front side of the circulating water tank 6. The connecting water tanks 63 communicate with the water storage tank 4. The lower ends of the connecting water tanks 63 extend above the circulating filter tank 61. The depth of the first end of the circulating filter tank 61 is smaller than the depth of the second end of the circulating filter tank 61. The bottom of the circulating filter tank 61 is sloped, and a circulation outlet is provided at the second end of the circulating filter tank 61. When the water injection pump 5 injects excess water, water outside the circulating filter tank 61 flows back into the water storage tank 4 from each connecting water tank 63. This prevents an increase in circulating water consumption due to excessive water injection by the water injection pump 5 and improves stability and reliability. The slope of the bottom of the circulating filter tank 61 allows water within the circulating filter tank 61 to flow out of the circulation outlet, preventing water from accumulating in the circulating filter tank 61.

[0013] A circulation water outlet pipe 64 extends from the circulation water outlet port, the water supply end of circulating water pump 7 is attached to the outer end of the circulation water outlet pipe, and the water outlet end of circulating water pump 7 is connected to circulation water pipe 71, a water injection outlet pipe 41 extends from the water injection outlet, the water supply end of water injection pump 5 is attached to the outer end of water injection outlet pipe 41, and the water outlet end of water injection pump 5 is connected to water injection pipe 51, and a filter cover 42 is provided at the inner end of water injection outlet pipe 41. The filter cover 42 is located inside the water storage tank 4 and filters out impurities and ice blocks inside the water storage tank 4, preventing impurities and ice blocks from getting into the water injection pump 5 and improving reliability and stability. The circulating water pump 7 is attached directly to the circulating water outlet pipe 64, and the water injection pump 5 is attached directly to the water injection outlet pipe 41. The circulating water outlet pipe 64 and the water injection outlet pipe 41 are made of a hard plastic material and are formed in the circulating water tank 6 and the water storage tank 4. The hard circulating water outlet pipe 64 and the water injection outlet pipe 41 improve the mounting strength of the circulating water pump 7 and the water injection pump 5, reduce vibration and noise, and shorten the length of the circulating water pipe 71 and the water injection pipe 51, reduce tangling, and improve reliability and stability.

[0014] A circulation drain port 65 is provided on the side of the circulation water outlet pipe 64, a water storage drain port 43 is provided at the bottom of the water storage tank 4, and a drain pipe 16 is provided in the housing 1, one end of the drain pipe 16 is formed at the bottom of the water storage tank 4 and the other end protrudes from the housing 1, the circulation drain port 65 is connected to the drain pipe 16 via a drain connection pipe 68, and the drain pipe 16 is provided with a drain plug 17. By removing the drain plug 17, the water in the circulation water tank 6 and the water storage tank 4 can be drained, making cleaning easier and preventing bacterial growth due to long-term stagnation of water.

[0015] A circulation drain port 65 is provided on the side of the circulation water outlet pipe 64, a water storage drain port 43 is provided at the bottom of the water storage tank 4, and a drain pipe 16 is provided in the housing 1. The circulation drain port 65 and the water storage drain port 43 are each connected to the drain pipe 16 via a drain connection pipe 68, and a drain solenoid valve is provided on the drain pipe 16. By controlling the automatic opening and closing of the drain solenoid valve, the water in the circulation water tank 6 and the water storage tank 4 is drained, eliminating the need for manual operation and making it convenient to use.

[0016] A mounting chamber is provided inside housing 1, water storage tank 4 is provided in the front of the mounting chamber, circulating water tank 6 is provided in the rear of the mounting chamber, the rear side of water storage tank 4 and the front side of circulating water tank 6 are formed as one unit, compressor 23, condenser 22, circulating water pump 7, and water injection pump 5 are all located below circulating water tank 6, ice tray 3 is provided at the top inside circulating water tank 6, ice making water tank 31 is provided within ice tray 3, and circulation water supply port 66 and water injection inlet 67 are provided on both the left and right sides of circulating water tank 6, both of which face ice making water tank 31. Because the rear side of water storage tank 4 and the front side of circulating water tank 6 are formed as one unit, the number of parts is reduced, the structure is simplified, costs are reduced, production efficiency is improved, and the unit is made compact and small.

[0017] A rotating rod 32 is provided on each side of ice making tray 3, and each of the two rotating rods 32 is rotatably mounted on circulating water tank 6. An ice drop drive motor 81 and an ice drop trigger switch 82 are provided on the outside of circulating water tank 6. One rotating rod is electrically connected to ice drop drive motor 81, and the other rotating rod is provided with trigger 33, which is linked to ice drop trigger switch 82. After ice making is complete, ice drop drive motor 81 rotates ice making tray 3, allowing the bullet-shaped ice in ice making water tank 31 to drop without having to be removed by hand. When ice making tray 3 rotates and returns, trigger 33 abuts ice drop trigger switch 82, which triggers ice drop trigger switch 82 to detect whether ice making tray 3 has returned to its original position for the next ice making operation, thereby improving the degree of automation.

[0018] Ice drop plate 83 is hinged to the front of ice tray 3, and ice storage basket 44 is movably mounted within water storage tank 4. Water for ice making is poured into the bottom of water storage tank 4, and bullet-shaped ice is stored in ice storage basket 44 at the top of water storage tank 4, maximizing the space in water storage tank 4 and making the unit compact and small. After ice making is complete, ice drop drive motor 81 rotates ice tray 3 backward by 90 degrees, causing the bullet-shaped ice in ice making water tub 31 to drop onto ice drop plate 83. As ice tray 3 rotates and returns to its original position, ice drop plate 83 moves forward and rotates downward, allowing the bullet-shaped ice on ice drop plate 83 to accurately drop into ice storage basket 44, preventing the accumulation of bullet-shaped ice and improving reliability and stability.
