[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an ice maker with a circulating sterilization function, comprising a water storage bucket, an ice water bucket, an ice-making assembly with an ice-making box and a water outlet assembly with a water outlet, the water storage bucket is connected to the water outlet assembly through a first water outlet pipe and a first water pump, the ice water bucket is connected to the water outlet assembly through a second water outlet pipe and a second water pump, the ice water bucket is connected to the ice-making box through a water inlet pipe and a third water pump, the bottom of the ice-making box is connected to the ice water bucket through a return pipe, and the ice water bucket is provided with an ultraviolet sterilization module for sterilizing the liquid in the ice water bucket.

[0005] In the above technical solution, the water storage bucket is connected to the water outlet assembly through the first water outlet pipe and the first water pump, and then drinking water flows out through the water outlet, which can provide drinking water for users; in addition, the bottom of the ice box is connected to the ice water bucket through the return pipe, and the melted water of the ice box flows back into the ice water bucket through the return pipe, which can reduce the water temperature of the ice water bucket. At the same time, the water in the ice water bucket is connected to the water outlet assembly through the second water outlet pipe and the second water pump, and then ice water flows out through the water outlet, which can provide ice water for users. Among them, the ice water bucket is connected to the ice box through the water inlet pipe and the third water pump to provide water for ice making. The ice water bucket is provided with an ultraviolet sterilization module, which can sterilize the water in the ice water bucket, which can improve the hygienic condition of users using ice water. At the same time, the water provided by the ice water bucket for ice making in the ice box is also sterilized, which can improve the hygienic condition of ice cubes, and the melted water of the ice box can be concentrated in the ice water bucket for sterilization. In the above technical solution, sterilization is performed by the ultraviolet sterilization module, and ice water flows and circulates between the ice water bucket and the ice making assembly to achieve sterilization of ice cubes and ice water, thereby improving the sterilization effect.

[0006] The utility model is further configured as follows: a heater is provided at the bottom of the water storage barrel.

[0007] In the above technical solution, the water in the water storage barrel can be heated and sterilized by providing a heater at the bottom of the water storage barrel, and the water in the water storage barrel can be heated and sterilized by connecting the water outlet assembly through the first water outlet pipe and the first water pump, thereby providing hot water to the user, which is beneficial to improving the user experience. In addition, the hot water can be connected to the water outlet assembly through the first water outlet pipe and the first water pump, and can also sterilize the first water outlet pipe, the first water pump and the water outlet assembly at high temperature, which can more effectively kill bacteria in the ice maker, which is beneficial to improving the sanitation of the ice maker.

[0008] The utility model is further configured as follows: the water storage bucket is connected to the ice water bucket through a third water outlet pipe and a fourth water pump.

[0009] In the above technical solution, the ultraviolet sterilization module sterilizes the ice water bucket, and then drains the water in the ice water bucket, and drains the water from the water storage bucket into the ice water bucket through the third water outlet pipe and the fourth water pump, starts the ice making process, and the water in the ice water bucket flows to the ice making box to make ice. After the ice making is finished, the water in the ice water bucket is sterilized again, and the water in the ice water bucket is drained again to clean the ice maker. Among them, the water put into the ice water bucket from the water storage bucket is hot water heated by the heater, and the hot water flows through the ice water bucket, and then enters the ice making box from the ice water bucket. The hot water then flows back to the ice water bucket from the return pipe, achieving high-temperature sterilization of the above-mentioned flow position, expanding the sterilization range, improving the sterilization effect, and being beneficial to the sanitation of the ice maker. It should be noted that during high-temperature sterilization, the ice making component is not started when the ice making process is started. In addition, the water storage bucket can also flow into the ice water bucket through the third water outlet pipe and the fourth water pump, so as to replenish the ice water bucket, without the need for external water pipes, and reducing the number of external water pipes.

[0010] The utility model is further configured as follows: a temperature sensor is arranged in the ice water bucket.

[0011] In the above technical solution, a temperature sensor is provided in the ice water bucket to detect the temperature in the ice water bucket. If the temperature exceeds the set temperature, ice making is started, and the melted water in the ice box flows back into the ice water bucket through the return pipe, lowering the temperature of the ice water bucket, thereby keeping the temperature in the ice water bucket constant and enabling users to use ice water at any time. In addition, when high temperature is used, it is also possible to detect whether the water temperature in the ice water bucket reaches the sterilization temperature, thereby ensuring the high temperature sterilization effect.

[0012] The utility model is further configured as follows: the heater is a heating tube, and the heating tube is arranged at the bottom of the water storage barrel.

[0013] In the above technical solution, the heater is a heating tube, which converts electrical energy into thermal energy and quickly transfers it to water, which is conducive to achieving efficient heating. The heating tube can also control the heating power by the current size, which is conducive to achieving water temperature control. Specifically, the water temperature can be controlled by controlling the current, and then the water temperature can be adjusted to meet the user's use requirements, which is conducive to improving the user experience. Among them, the heating tube is arranged at the bottom of the water storage barrel, so that the heating tube is located at a relatively low position, which can reduce the minimum height of the water immersion heating tube, which is conducive to reducing the risk of dry burning of the heating tube.

[0014] The utility model is further configured as follows: the ultraviolet sterilization module comprises an ultraviolet sterilization lamp and a scattering lens, and the scattering lens is used for scattering ultraviolet light.

[0015] In the above technical solution, the ultraviolet sterilization module includes an ultraviolet sterilization lamp and a scattering lens. The ultraviolet sterilization lamp generates ultraviolet light to kill bacteria in the ice bucket, and then scatters the ultraviolet light through the scattering lens, so that the ultraviolet light can cover the entire ice bucket more evenly, which is beneficial to improve the sterilization effect. Among them, by scattering the ultraviolet light through the scattering lens, the ultraviolet light can cover a larger range, and a smaller ultraviolet sterilization lamp can be selected when the same coverage area is required, which is beneficial to reduce the cost of the ultraviolet sterilization lamp, and then reduce the product cost; specifically, when the same coverage area is required, a smaller ultraviolet sterilization lamp can be selected, which can reduce the power requirements of the ultraviolet sterilization lamp, reduce the heat generated by the ultraviolet sterilization lamp, and have less impact on the temperature of the ice water, which is more energy-saving and environmentally friendly. In addition, by scattering the ultraviolet light through the scattering lens, a smaller ultraviolet sterilization lamp can be selected when the same coverage area is required, which can reduce the space occupied by the ultraviolet sterilization module, which is beneficial to the installation and arrangement of other components, and also beneficial to reducing the volume of the ice maker. In addition, the use of ultraviolet light for sterilization will not produce chemical residues and is safer.

[0016] The utility model is further configured as follows: the ultraviolet sterilization module is installed on the top plate of the ice water bucket.

[0017] In the above technical solution, by installing the ultraviolet sterilization module on the top plate of the ice water bucket, the precipitation of impurities in the water onto the ultraviolet sterilization module can be reduced, which is beneficial to reduce the risk of the ultraviolet sterilization module being shielded by impurities due to long-term operation of the ice maker and thus affecting the sterilization effect.

[0018] The utility model is further configured as follows: the water outlet assembly has a water outlet and two water inlets, and the two water inlets are respectively connected to the first water outlet pipe and the second water outlet pipe.

[0019] In the above technical solution, the first water outlet pipe and the second water outlet pipe are connected through two water inlets to realize the diversion of hot water and ice water, so that the ice water bucket and the water storage bucket are relatively independent. In addition, the water storage bucket and the ice water bucket share a water outlet, and the water outlet can be sterilized by the hot water in the water storage bucket, which can avoid the ice water outlet of the two separate water outlets being unable to sterilize.

[0020] The utility model is further configured as follows: the ice-making assembly also includes a first ice storage box and a second ice storage box arranged in the ice-making box, the second ice storage box is arranged below the first ice storage box, an ice-making element is arranged above the first ice storage box, and the water supply port of the water inlet pipe is arranged above the first ice storage box for supplying water to the first ice storage box.

[0021] In the above technical solution, water flows from the water supply port into the first ice storage box through the water inlet pipe, and supplies water for the ice-making element to make ice in the first ice storage box. The water supply port of the water inlet pipe is arranged above the first ice storage box, which can prevent the water supply port from being blocked by ice cubes and ensure the subsequent normal water supply. In addition, the second ice storage box is arranged below the first ice storage box. When transferring ice cubes to the second ice storage box, the ice cubes can slide down automatically due to the influence of gravity, which is conducive to improving the efficiency of ice cube transfer.

At the same time, the water in the ice water bucket 200 is connected to the water outlet assembly 400 through the second water outlet pipe 210 and the second water pump 220, and then ice water flows out through the water outlet 410, thereby providing ice water for users. Among them, the ice bucket 200 is connected to the ice box 310 through the water inlet pipe 230 and the third water pump 240 to provide water for ice making. The ice bucket 200 is provided with an ultraviolet sterilization module 500, which can sterilize the water in the ice bucket 200, and can improve the sanitary conditions of users using ice water. At the same time, the water provided by the ice bucket 200 to the ice box 310 for ice making is also sterilized, which can improve the sanitary conditions of ice cubes, and can also concentrate the melted water of the ice box 310 into the ice bucket 200 for sterilization. In this embodiment, the ultraviolet sterilization module 500 is used for sterilization, and water flows between the ice bucket 200 and the ice making assembly 300 to achieve the sterilization of ice cubes and ice water, and improve the sterilization effect.

[0035] Specifically, a heater is provided at the bottom of the water storage barrel 100. The heater provided at the bottom of the water storage barrel 100 can heat and sterilize the water in the water storage barrel 100, and the water in the water storage barrel 100 can be heated and sterilized, and the water in the water storage barrel 100 can be heated and sterilized through the heater, and then connected to the water outlet assembly 400 through the first water outlet pipe 110 and the first water pump 120, thereby providing hot water to the user, which is conducive to improving the user experience.

[0036] Specifically, Figure 4 and Figure 5As shown, the water storage bucket 100 is connected to the ice water bucket 200 through the third water outlet pipe 140 and the fourth water pump 150. The ultraviolet sterilization module 500 sterilizes the ice water bucket 200, and then drains the water in the ice water bucket 200, and discharges water from the water storage bucket 100 into the ice water bucket 200 through the third water outlet pipe 140 and the fourth water pump 150, and starts ice making. The water in the ice water bucket 200 flows to the ice making box 310 to make ice. After ice making is finished, the water in the ice water bucket 200 is sterilized again, and the water in the ice water bucket 200 is drained again to clean the ice maker. The water put from the water storage bucket 100 into the ice water bucket 200 is hot water heated by a heater, and the hot water flows through the ice water bucket 200, and then enters the ice making box 310 from the ice water bucket 200, and then flows back to the ice water bucket 200 from the return pipe 311, so as to achieve high-temperature sterilization of the above-mentioned flow-through position, expand the sterilization range, improve the sterilization effect, and be beneficial to the sanitation of the ice maker. It should be noted that during high-temperature sterilization, the ice making part 380 is not started when the ice making process is started. In addition, the water storage bucket 100 can also flow into the ice water bucket 200 through the third water outlet pipe 140 and the fourth water pump 150, so as to replenish the ice water bucket 200 with water, and no external water pipe is required, thereby reducing the number of external water pipes.

[0037] The heater is a heating tube, which is arranged at the bottom of the water storage barrel 100. The heater is a heating tube, which converts electrical energy into thermal energy and quickly transfers it to water, which is conducive to achieving efficient heating. The heating tube can also control the heating power by the current size, which is conducive to achieving the control of water temperature. Specifically, the water temperature can be controlled by controlling the current, and then the water temperature can be adjusted to meet the user's use requirements, which is conducive to improving the user experience. The heating tube is arranged at the bottom of the water storage barrel 100, so that the heating tube is located at a relatively low position, which can reduce the minimum height of the water immersion heating tube, which is conducive to reducing the risk of dry burning of the heating tube.

[0038] Specifically, Figure 3 As shown, a temperature sensor 250 is provided in the ice water bucket 200. The temperature in the ice water bucket 200 is detected by the temperature sensor 250 provided in the ice water bucket 200. If the temperature exceeds the set temperature, ice making is started, and the melted water in the ice making box 310 flows back into the ice water bucket 200 through the return pipe 311, thereby lowering the temperature of the ice water bucket 200, and the temperature in the ice water bucket 200 can be kept constant, so that the user can take ice water at any time. In addition, when high-temperature sterilization is adopted, it is also possible to detect whether the water temperature in the ice water bucket 200 reaches the sterilization temperature, thereby ensuring the high-temperature sterilization effect.

[0039] Specifically, Figure 6As shown, the ultraviolet sterilization module 500 includes an ultraviolet sterilization lamp 510 and a scattering lens 520, and the scattering lens 520 is used to scatter ultraviolet light. The ultraviolet sterilization module 500 includes an ultraviolet sterilization lamp 510 and a scattering lens 520. The ultraviolet sterilization lamp 510 generates ultraviolet light to kill bacteria in the ice bucket 200, and then the ultraviolet light is scattered by the scattering lens 520, so that the ultraviolet light can cover the entire ice bucket 200 more evenly, which is beneficial to improve the sterilization effect. Among them, by scattering the ultraviolet light by the scattering lens 520, the ultraviolet light can cover a larger range, and a smaller ultraviolet sterilization lamp 510 can be selected when the same coverage area is required, which is beneficial to reduce the cost of the ultraviolet sterilization lamp 510, and then reduce the product cost; specifically, when the same coverage area is required, a smaller ultraviolet sterilization lamp 510 can be selected, which can reduce the power requirements of the ultraviolet sterilization lamp 510, reduce the heat generated by the ultraviolet sterilization lamp 510, and have a smaller impact on the temperature of the ice water, which is more energy-saving and environmentally friendly. In addition, by scattering the ultraviolet light through the scattering lens 520, a smaller ultraviolet sterilization lamp 510 can be selected when the same coverage area is required, which can reduce the space occupied by the ultraviolet sterilization module 500, facilitate the installation and arrangement of other components, and also help to reduce the volume of the ice maker. In addition, the use of ultraviolet light sterilization will not produce chemical residues and is safer.

[0040] Among them, Figure 6 As shown, the ultraviolet sterilization module 500 also includes a support frame 550 for fixing the ultraviolet sterilization lamp 510, a PCB board 540 for controlling the ultraviolet sterilization lamp 510, a heat sink 530 for heat dissipation, and a sealing ring 560 arranged between the support frame 550 and the ultraviolet sterilization lamp 510 for sealing.

[0041] Specifically, Figure 4 As shown, the ultraviolet sterilization module 500 is installed on the top plate of the ice water bucket 200. By installing the ultraviolet sterilization module 500 on the top plate of the ice water bucket 200, it is possible to reduce the precipitation of impurities in the water onto the ultraviolet sterilization module 500, which is conducive to reducing the risk of the ultraviolet sterilization module 500 being shielded by impurities and affecting the sterilization effect due to the long-term operation of the ice maker.

[0042] Specifically, Figure 4 As shown, the water outlet assembly 400 has a water outlet 410 and two water inlets, and the two water inlets are connected to the first water outlet pipe 110 and the second water outlet pipe 210 respectively. The two water inlets are connected to the first water outlet pipe 110 and the second water outlet pipe 210 to realize the diversion of hot water and ice water, so that the ice water bucket 200 and the water storage bucket 100 are relatively independent. In addition, the water storage bucket 100 and the ice water bucket 200 share a water outlet 410, and the water outlet 410 can be sterilized by the hot water in the water storage bucket 100, which can avoid the ice water outlet of the two water outlets 410 being unable to be sterilized.

[0043] Specifically, Figure 2 and Figure 5 As shown, the ice making assembly 300 further includes a first ice storage box 320 and a second ice storage box 330 disposed in the ice making box 310, the second ice storage box 330 is disposed below the first ice storage box 320, an ice making member 380 is disposed above the first ice storage box 320, and a water supply port 231 of a water inlet pipe 230 is disposed above the first ice storage box 320 for supplying water to the first ice storage box 320. Water flows into the first ice storage box 320 from the water supply port 231 through the water inlet pipe 230, and water is supplied to the ice making member 380 for making ice in the first ice storage box 320. Among them, the water supply port 231 of the water inlet pipe 230 is disposed above the first ice storage box 320, which can prevent the water supply port 231 from being blocked by ice cubes, thereby ensuring normal subsequent water supply. In addition, the second ice storage box 330 is disposed below the first ice storage box 320, and when the ice cubes are transferred to the second ice storage box 330, the ice cubes can slide down automatically under the influence of gravity, which is conducive to improving the efficiency of ice cube transfer.

[0044] Among them, Figure 2 As shown, the first ice storage box 320 is rotatably connected with the ice making box 310, and the ice making box 310 is provided with a flipping mechanism 350 for flipping the first ice storage box 320, and the flipping mechanism 350 is transmission-connected with the first ice storage box 320 so that the flipping mechanism 350 can switch between the ice making state and the ice dropping state. The second ice storage box 330 is provided with a first outlet 331, a second outlet 332, an ice pushing assembly 360 for pushing the ice cubes in the second ice storage box 330 out from the first outlet 331 or the second outlet 332, and an ice crushing assembly 370 arranged at the second outlet 332. In addition, a third ice storage box 340 is further arranged below the second outlet 332 for receiving the crushed ice crushed by the ice crushing assembly 370. When making ice, the ice water bucket 200 flows water into the first ice storage box 320 from the water supply port 231 through the water inlet pipe 230 and the third water pump 240 to supply water for ice making. After the ice cubes are made, the flip mechanism 350 is started to switch from the ice making state to the ice falling state, and the first ice storage box 320 is flipped, and the ice cubes fall into the second ice storage box 330, and then the ice is pushed by the ice pushing assembly 360.
