[0002] With the popularity of cold drinks, people's demand for ice cubes is increasing, and ice machines are increasingly widely used in beverage shops. Ice machines are refrigeration equipment that combines compressors, condensers, etc. Therefore, when the ice machine is working, the condenser inside it will generate a lot of heat, and the condenser will be dissipated. Existing ice machines usually use air cooling to dissipate heat, using the fan to take away the heat from the condenser. However, the existing heat dissipation method has a low heat dissipation efficiency, and the condenser will discharge the heat from the condenser into the room, causing the indoor temperature to rise, which reduces the ice-making efficiency of the ice machine.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] Embodiment 1

[0032] The present embodiment relates to an ice maker cooling system, which can improve the heat dissipation efficiency and ice making efficiency of the ice maker.

[0033] In terms of overall structure, Figure 1 As shown, the ice-making machine cooling system of this embodiment includes a compressor 1, an evaporator 2, an expansion valve 3 and a condenser.

[0034] The condenser includes a condensing water tank 5 connected in series to a tap water pipe 4, and a heat exchange pipe 6 arranged in the condensing water tank 5. Both ends of the heat exchange pipe 6 extend out of the condensing water tank 5 and are connected to the compressor 1 and the expansion valve 3 respectively.

[0035] As shown in the above structure, the ice maker cooling device of this embodiment is provided with a condensing water tank 5 connected in series to the tap water pipe 4. The heat exchange tube 6 in the condensing water tank 5 can be cooled by tap water, thereby improving the heat dissipation efficiency. At the same time, the heat will not be dissipated into the room to cause the room temperature to rise, thereby improving the ice making efficiency of the ice maker.

[0036] Based on the above overall introduction, specifically, continue to combine Figure 1 As shown, it can be understood that the ice maker is arranged indoors, and the existing air-cooling heat dissipation method will dissipate heat into the room, causing the indoor temperature to rise and the ice-making efficiency to decrease. At the same time, the indoor personnel will feel uncomfortable due to the temperature rise, thus affecting the use of the ice maker. The condensing water tank 5 of this embodiment is connected in series to the tap water pipe 4, and the heat exchange tube 6 in the condensing water tank 5 is cooled by tap water, and the heat can be discharged into the tap water. In addition, the ice maker is usually installed in places with high water consumption, such as beverage stores in business districts, and the flow rate of the tap water pipe 4 is large. The tap water can effectively cool the heat exchange tube 6, thereby preventing the heat of the condenser from entering the room, causing discomfort to the indoor personnel, and improving the ice-making efficiency of the ice maker.

[0037] In order to improve the quality of the ice cubes produced, as a preferred implementation form, the ice maker cooling system of this embodiment further includes a reverse osmosis treatment unit 7, a water intake pipe 71, a clean water pipe 72 and an overflow valve 73. The tap water in the condensation water tank 5 flows into the reverse osmosis treatment unit 7 through the water intake pipe 71, and the clean water produced by the reverse osmosis treatment unit 7 flows into the ice box 74 through the clean water pipe 72, and the waste water generated by the reverse osmosis treatment unit 7 is discharged into the sewer through the overflow valve 73. Through the arrangement of the reverse osmosis treatment unit 7, clean water can be produced for ice making, thereby improving the quality of the ice cubes produced.

[0038] Specifically, the reverse osmosis treatment unit 7 utilizes the osmosis principle to remove soluble impurities and inorganic salts in tap water, producing clean water containing less inorganic salts and waste water with a higher inorganic salt concentration. The clean water is input into the ice making box 74 through the clean water pipe 72 for making ice cubes, and the waste water is discharged into the sewer through the overflow valve 73.

[0039] In addition, as a preferred implementation form, a booster pump 75 is connected in series to the water intake pipe 71 of this embodiment to increase the water pressure flowing to the reverse osmosis treatment unit 7, thereby increasing the water output of the purified water. At the same time, the reverse osmosis treatment unit 7 can use an RO filter element, which can use a conventional RO filter element well known to those skilled in the art, which has an RO reverse osmosis membrane and can output purified water and wastewater. The use of an RO filter element can remove bacteria, viruses, inorganic salts and organic impurities in the water, improve the water quality of purified water, and improve the hygiene of purified water and produced ice cubes.

[0040] In addition, in order to further improve the quality and sanitation of purified water and ice cubes, as a preferred embodiment, a pretreatment unit 76 is also provided on the water intake pipe 71. The pretreatment unit 76 includes a PP cotton filter element and an activated carbon filter element. The PP cotton filter element can perform preliminary filtration on the tap water to remove coarser particulate impurities, sludge, colloids and suspended matter in the tap water. The activated carbon filter element can remove chlorine and adsorb odor, discoloration and some heavy metals in the water. Thereby, the tap water is further filtered and treated, the water quality of purified water is improved, and the sanitation of purified water and ice cubes is improved. In the specific implementation, the pretreatment unit 76 is arranged before the reverse osmosis treatment unit 7 to pretreat the tap water.

[0041] In order to facilitate the use of purified water, as a preferred implementation form, a purified water tank 77 for storing purified water is connected in series to the purified water pipe 72 of this embodiment, and a faucet 78 for obtaining purified water is provided on the purified water tank 77. It can be understood that the rate of preparing purified water by the reverse osmosis treatment unit 7 is low, and it is difficult to meet the demand for the use of a large amount of purified water. Therefore, by providing the purified water tank 77, a certain amount of purified water can be stored in advance, and when purified water is needed, sufficient purified water can be supplied to the ice box 74 and the faucet 78, so as to provide a large amount of purified water for use in a short time.

[0042] The reverse osmosis treatment unit 7 generates a large amount of waste water when producing clean water, and discharging the waste water into the sewer will cause a waste of water resources. Therefore, as a preferred implementation form, a mixing water tank 8 is connected in series to the water intake pipe 71 of this embodiment, and a waste water pipe 81 is connected between the mixing water tank 8 and the reverse osmosis treatment unit 7, and the waste water can flow into the mixing water tank 8 through the waste water pipe 81. When the waste water enters the water tank through the waste water pipe 81, the waste water can be fully mixed with the tap water. It can be understood that in the process of producing clean water by the reverse osmosis treatment unit 7, the salt concentration of the waste water is too high, and clean water can no longer be produced through the osmotic membrane. When the waste water is mixed with the tap water, the waste water is diluted and can be used again. Therefore, by setting the mixing water tank 8, part of the waste water can be recycled, thereby saving water resources and reducing the consumption of tap water.

[0043] In specific implementation, the mixing water tank 8 may be preferably disposed between the pretreatment unit 76 and the reverse osmosis treatment unit 7, so that the tap water is mixed with the wastewater after being treated by the pretreatment unit 76, so as to avoid residual sludge and other impurities in the mixing water tank 8, which may affect the water quality in the mixing water tank 8 and thus reduce the service life of the pretreatment unit 76 and the reverse osmosis treatment unit 7. At the same time, the bottom of the mixing water tank 8 may preferably be provided with a drain port, through which the mixed water in the mixing water tank 8 can be obtained and used for cleaning, etc., so as to make full use of the wastewater and save water resources.

[0044] Among them, as a preferred implementation form, the waste water pipe 81 of this embodiment is provided with a waste water pump 82, and the waste water pump 82 can transport the waste water tank to the mixing water tank 8, and can control the amount of waste water flowing into the mixing water tank 8, so that the tap water and the waste water are fully mixed. In addition, as a preferred implementation form, a one-way valve 9 is provided on the water intake pipe 71, and the one-way valve 9 is located between the mixing water tank 8 and the condensation water tank 5, which can prevent the waste water in the mixing water tank 8 from flowing into the tap water pipe 4 through the condensation water tank 5, and prevent the tap water pipe 4 from being polluted.

[0045] In the mixing water tank 8, after the tap water and wastewater are mixed, the salt concentration thereof needs to meet the requirements of the reverse osmosis treatment unit 7. Therefore, as a preferred embodiment, a TDS detection device is provided in the mixing water tank 8 to detect the salt concentration after the tap water and wastewater are mixed. When the salt concentration exceeds a preset value, the overflow valve 73 is opened, and the wastewater is discharged into the sewer from the overflow valve 73. When the salt concentration is lower than the preset value, the wastewater is input into the mixing water tank 8 through the wastewater pipe 81 to realize the recycling of the wastewater, thereby achieving the requirement of water conservation.

[0046] Moreover, in the process of utilizing wastewater, the amount of wastewater discharged by the reverse osmosis treatment unit 7 is greater than the amount of wastewater recycled, and the water volume and pressure in the mixing water tank 8 will continue to increase. Therefore, a pressure sensor is also provided in the mixing water tank 8. When the water pressure in the mixing water tank 8 exceeds a certain threshold, the overflow valve 73 opens, and the wastewater is discharged into the sewer from the overflow valve 73.

[0047] The ice maker cooling system described in the utility model is provided with a condensing water tank 5 connected in series to a tap water pipe 4. The heat exchange tube 6 in the condensing water tank 5 can be cooled by tap water, thereby improving the heat dissipation efficiency and avoiding the heat dissipation into the room causing the room temperature to rise, thereby improving the ice making efficiency of the ice maker.
