Description

Technical Field

[0001] The utility model relates to the technical field of ice making machines, in particular to a transparent ice making machine with a spray type circulation. Background Art

[0002] An ice making machine is a machine used to quickly make ice. During the ice making process, circulating water flows through an ice making mold on an evaporator to discharge air bubbles in the water, thereby making transparent ice with high transparency. When making bullet ice, the ice making mold is inserted into an ice making box, and the ice making box is filled with water for ice making. During the circulation process, usually two circulation methods are adopted. The first one is to circulate the water in the ice making box through a water pump inside the ice making box. This circulation method has a fast circulation speed and little temperature loss during the circulation process. However, due to the small capacity of the ice making box and small circulation volume, filtration cannot be carried out during the circulation process, the transparency of the made ice is not high, and the ice making box needs to be rotated to pour out ice, and a connection needs to be established through a hose. The hose is easily broken due to repeated bending, and the reliability and stability are poor. The second one is to continuously pump the water in a water tank at the bottom of the ice making machine into the ice making box, and the water in the ice making box overflows and flows back into the water tank to form a circulation. Although this method can filter the water during the circulation process, reduce impurities, and has a fast circulation speed, and the made ice has high transparency, the capacity of the water tank is too large, which easily causes the water in the ice making box to lose temperature, resulting in a slow ice making speed and high energy consumption. On the other hand, the ice making box is in a long strip shape, and the circulating water injection port is arranged at one end of the ice making box. The water flow needs to flow from one end of the ice making box to the other end, resulting in a long water flow travel distance and a long water flow time in the ice making box, resulting in a slow circulation speed. If there are impurities in the liquid level, it is difficult to flush out of the ice making box. Moreover, when circulating water is injected, the water flow speed is fast on the side close to the circulating water injection port, while the water flow speed is slow on the side far from the circulating water injection port, which leads to uneven transparency of the made ice. Therefore, it is necessary to make improvements. Content of the Utility Model

[0028] The following is only a preferred embodiment of the present utility model, and does not limit the protection scope of the present utility model accordingly.

[0029] A spray-type circulating transparent ice maker, as Figures 1 to 4 shown, includes an outer shell, an inner shell 2, an evaporator 62, a compressor 61, a condenser 63, an ice making box 41 and an ice making mold 64. The inner shell 2 is fixedly installed inside the outer shell. The ice making box 41 is arranged at the upper part of the inner shell 2. The compressor 61 and the evaporator 62 are respectively arranged between the outer shell and the inner shell 2. The condenser 63 is arranged above the ice making box 41. The ice making mold 64 is arranged below the condenser 63 and inserted into the ice making box 41. An ice making tank 21 is arranged at the upper part of the inner shell 2. A water storage tank 22 is arranged at the lower part of the inner shell 2. The ice making tank 21 and the water storage tank 22 are arranged in a staggered manner front and back. A circulation spray pipe 34 is arranged at the upper part of the ice making tank 21. The circulation spray pipe 34 is arranged along the length direction of the ice making box 41 and is located above the ice making box 41. A plurality of spray ports 341 are arranged at intervals on the circulation spray pipe 34. The spray ports 341 face the ice making box 41. A circulation water inlet 31 is arranged at the lower part of the ice making tank 21. A circulation water pipe 35 is connected between the circulation spray pipe 34 and the circulation water inlet 31. A circulation water pump 36 is arranged on the circulation water pipe 35.

[0030] Traditional transparent ice-making machines circulate water by pumping water from the ice-making box 41 or the water storage tank 22. When pumping water from the ice-making box 41, the ice-making box 41 needs to rotate to pour out ice, and usually, the ice-making box 41 is connected to the circulating water pump 36 through a hose. After long-term use, the hose will be repeatedly bent and broken, resulting in poor reliability and stability. In addition, the capacity of the ice-making box 41 is small, the circulating water volume is small, and a filtering device cannot be installed. When pumping water from the water storage tank 22, due to the large capacity of the water storage tank 22, the water in the ice-making box 41 loses temperature, resulting in a long ice-making time, low efficiency, and high energy consumption. However, in the present utility model, the circulating water is evenly sprayed from each spray port 341 of the circulating spray pipe 34 into the ice-making box 41. The water flow in the ice-making box 41 flows evenly from the back to the front and overflows from the ice-making box 41 into the ice-making tank 21, thereby improving the flow uniformity and stability of the water flow, making the water flow speed around each ice-making mold 64 the same, shortening the water flow path, and further improving the transparency of the ice cubes. The water overflowing from the ice-making box 41 enters the ice-making tank 21 and then is pumped back to the circulating spray pipe 34 by the circulating water pump 36 through the circulating water pipe 35, thereby establishing a circulating loop. The circulating water does not need to flow through the water storage tank 22, reducing the temperature loss of the water in the ice-making box 41, increasing the ice-making speed, and reducing energy consumption.

[0031] Specifically, a circulating water tank 3 is provided at the bottom of the ice-making tank 21. The circulating water inlet 31 is arranged at the bottom of the circulating water tank 3, and a filter plate 32 is covered on the upper part of the circulating water tank 3. The circulating water is stored in the circulating water tank 3 to facilitate the operation of the circulating water pump 36. The circulating water flows into the circulating water tank 3 through the filter plate 32, thereby filtering the circulating water and preventing impurities from flowing back into the ice-making box 41, improving the ice-making quality, with a simple structure and low cost.

[0032] Specifically, a water supply port 211 is provided at the lower part of the water storage tank 22, and a water injection port 212 is provided at the upper part of the ice-making tank 21. The water injection port 212 is communicated with the circulating spray pipe 34 or the ice-making box 41. A water supply pipe 51 is connected between the water supply port 211 and the water injection port 212, and a water supply pump 52 is arranged on the water supply pipe 51. During ice-making, it is necessary to first pump the water in the water storage tank 22 from the water injection port 212 to the ice-making box 41 through the water supply pump 52. When the ice-making box 41 is full of water, continue to pump for a certain time to make the water in the ice-making box 41 overflow into the circulating water tank 3, and then start the circulating water pump 36 to inject the water in the circulating water tank 3 into the ice-making box 41 through the circulating spray pipe 34.

[0033] Specifically, the circulating water inlet 31 and the water supply port 211 are respectively arranged on the left and right sides of the ice-making tank 21. The circulating water inlet 31 is connected to the first end of the circulating spray pipe 34, and the second end of the circulating spray pipe 34 is a closed end. The water supply port 211 faces the ice-making box 41 and is communicated with the ice-making box 41. The circulation and water injection are separated into two independent pumping structures, reducing interference with each other, avoiding water accumulation in the pipeline, and being more hygienic and clean.

[0034] Specifically, the water storage tank 22 is arranged on the front side of the ice-making tank 21. The circulating spray pipe 34 is arranged at the rear side inside the ice-making tank 21 and behind the ice-making mold 64. The circulating spray pipe 34 horizontally penetrates through the inner cavity of the ice-making box 41. An installation chamber 11 is enclosed among the water storage tank 22, the ice-making tank 21 and the outer shell. The installation chamber 11 is located below the ice-making tank 21 and behind the water storage tank 22. The compressor 61 and the evaporator 62 are respectively fixedly installed in the installation chamber 11. When making ice, the circulating water flows forward from the rear of the ice-making mold 64, thereby shortening the water flow path, maintaining the stability of the water flow, and preventing the occurrence of turbulent flow. Since the ice-making tank 21 does not need to occupy a large space, the depth of the ice-making tank 21 is reduced to form the installation chamber 11, improving the structural compactness and reducing the volume.

[0035] Specifically, the circulating water inlet 31 is connected with a circulating water inlet pipe 33. The upper end of the circulating water inlet pipe 33 is integrally formed with the inner shell 2. The water inlet end of the circulating water pump 36 is connected to the lower end of the circulating water inlet pipe 33, and the water outlet end of the circulating water pump 36 is connected to the lower end of the circulating water pipe 35. Through the circulating water inlet pipe 33, the circulating water pump 36 can be rigidly connected to the inner shell 2, and there is no need to set up a fixing mechanism to fix the circulating water pump 36, preventing the circulating water pump 36 from resonating during operation, simplifying the structure and reducing the cost.

[0036] Specifically, at least two fixing blocks 342 are arranged at intervals on the rear side surface of the circulating spray pipe 34. Each fixing block 342 is provided with at least one fixing hole 343. At least two fixing grooves 24 are formed in the upper edge of the rear side surface of the ice-making tank 21. A threaded hole is arranged at the bottom of the fixing groove 24. Each fixing block 342 is embedded in each fixing groove 24, and each fixing hole 343 is penetrated by a fastening screw, and the fastening screw is threadedly connected with the threaded hole. The circulating spray pipe 34 is fixedly installed on the inner shell 2 through two fixing blocks 342. The connection structure is simple and reliable, convenient for disassembly and replacement, reducing the production and maintenance costs, and not contacting the ice-making box 41, avoiding the risk of hose rupture when the ice-making box 41 rotates and pours ice.

[0037] Specifically, the bottom of the ice-making tank 21 is inclined towards the water storage tank 22. The circulating water inlet 31 is arranged on the left or right side of the bottom of the circulating water tank 3, and the bottom of the circulating water tank 3 is inclined towards the circulating water inlet 31. The inclined bottom of the ice-making tank 21 forms a slope, thereby guiding the water in the ice-making tank 21 to flow towards the circulating water tank 3 and the water storage tank 22. The inclined bottom of the circulating water tank 3 forms a slope, thereby guiding the water in the circulating water tank 3 to flow towards the circulating water pipe 33, so as to avoid water accumulation, prevent bacteria from breeding, and be clean and hygienic.

[0038] Specifically, the left and right ends of the ice-making box 41 are respectively rotatably installed on the left and right sides of the ice-making tank 21. One end of the ice-making box 41 is drivingly connected to an ice-dumping driving mechanism 7. The upper edge of the front part of the ice-making box 41 is hinged with an ice-guiding plate 42. A ice storage basket 23 is movably installed on the upper part of the water storage tank 22. The front end of the ice-guiding plate 42 extends to the rear of the ice storage basket 23. The ice-dumping driving mechanism 7 adopts a reduction motor, which is fixedly installed on the outer side of the inner shell 2. The main shaft of the reduction motor is rotationally connected to the rotating shaft of any one end of the ice-making box 41. After ice-making is completed, the ice-making box 41 is driven by the reduction motor to rotate towards the ice storage basket 23, and the ice cubes fall into the ice storage basket 23 along the ice-guiding plate 42. The ice-guiding plate 42 can prevent the ice cubes from falling into the ice-making tank 21.

[0039] Specifically, the outer shell includes a front cover 12, a rear cover 13, a front side shell 14, a rear side shell 15 and a base 16. The rear part of the rear cover 13 is hinged to the front part of the front cover 12. The rear part of the front side shell 14 is snap-fitted and fixed to the front part of the rear side shell 15. The front cover 12 is covered on the upper part of the front side shell 14. The rear cover 13 is fixedly installed on the upper part of the rear side shell 15. The base 16 is fixedly installed on the lower parts of the front side shell 14 and the rear side shell 15. Both the base 16 and the rear side shell 15 are provided with a plurality of heat dissipation holes 17. The outer shell is assembled by a plurality of components, which is convenient for disassembly and installation, easy for production and maintenance. When filling water and taking ice, only need to rotate and open the front cover 12, which reduces the opening size and the risk of foreign impurities entering. The compressor 61 and the evaporator 62 are cooled through the heat dissipation holes 17, improving the operation stability.

[0040] The working principle of the present utility model is as follows:

[0041] When making ice, as Figure 4 shown, start the water supply pump 52 to pump the water in the water storage tank 22 from the water injection port 212 into the ice-making box 41. When the ice-making box 41 is full of water, continue pumping for a certain time to make the water in the ice-making box 41 overflow into the circulating water tank 3. After the water supply pump 52 stops running, start the circulating water pump 36 to inject the water in the circulating water tank 3 into the ice-making box 41 through the circulating spray pipe 34; the circulating water flows from the rear to the front and overflows from the ice-making box 41 to flow into the circulating water tank 3. When the water in the circulating water tank 3 is too much, the water in the circulating water tank 3 overflows and flows into the water storage tank 22;

[0042] After ice making is completed, the condenser 63 heats up to cause the ice cubes to separate from the ice making mold 64 and fall into the ice making box 41. Then, the ice making box 41 is driven by the ice dumping drive mechanism 7 to rotate towards the ice storage basket 23, and the ice cubes fall into the ice storage basket 23 along the ice guiding plate 42. The ice guiding plate 42 can prevent the ice cubes from falling into the ice making tank 21, thereby completing one round of ice making. When starting the next round of ice making, only the water supply pump 52 needs to be started to fill the ice making box 41 with water.

[0043] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
