The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0042] Embodiment 1

[0043] Referring to Figure 1-7 , the present utility model provides a thermos flask that can ensure the hygienic quality of cooled boiled water, including a casing 1, a thermos flask 2, and an ice-making module 3. The casing 1 is provided with a water outlet 11; the thermos flask is arranged on the casing 1 and used for supplying hot water; the ice-making module 3 is arranged inside the casing 1 and used for making ice and supplying cold water. Among them, the water outlet end of the thermos flask 2 is communicated with the water outlet 11 through a first hot water outlet pipe; the ice-making module 3 includes an ice-making box 31, a cold water tank 32, a cold water inlet pipe 331, a first cold water outlet pipe 332, a second cold water outlet pipe, and a hot water inlet pipe 333. The ice-making box 31, the cold water inlet pipe 331, the cold water tank 32, and the first cold water outlet pipe 332 are sequentially communicated to form a water circulation system; the water inlet end of the hot water inlet pipe 333 is communicated with the water outlet end of the thermos flask 2, and its water outlet end is communicated with the ice-making box 31; the water outlet end of the cold water tank 32 is communicated with the water outlet 11 through the second cold water outlet pipe.

[0044] In addition, it further includes a cooling water pipe 334 at least partially arranged inside the cold water tank 32. The water outlet end of the thermos flask 2 is communicated with the water inlet end of the cooling water pipe 334 through a second hot water outlet pipe. The water outlet end of the cooling water pipe 334 is communicated with the first hot water outlet pipe at a certain position through a pipeline for mixing hot water and cold water to form cooled boiled water.

[0045] In this embodiment, the cooling water pipe 334 is an ordinary water pipe. When hot water flows through the cooling water pipe 334, it only exchanges heat with the cold water in the cold water tank 32 without contacting the cold water.

[0046] Thus, when hot water needs to be output, the thermos flask 2 can directly output hot water to the water outlet 11 through the first hot water outlet pipe; when cold water needs to be output, the thermos flask 2 can first inject hot water into the ice-making box 31 through the hot water inlet pipe. After the hot water in the ice-making box 31 is cooled to a specified temperature, the cold water is pumped back into the cold water tank 32 through the cold water inlet pipe 331. Subsequently, the cold water tank 32 outputs cold water to the water outlet 11 through the second cold water outlet pipe; when cooled boiled water needs to be output, the hot water in the thermos flask 2 can be output through the first hot water outlet pipe and the second hot water outlet pipe respectively. When the hot water output by the second hot water outlet pipe flows through the cooling water pipe 334, it can exchange heat with the cold water in the cold water tank 32 and be cooled into cold water. Subsequently, the cold water is mixed with the hot water output by the first hot water outlet pipe and modulated into cooled boiled water at a specified temperature and then output.

[0047] Thus, for the cooled boiled water made in the above manner, since the cold water in the cold water tank 32 is not used for modulation, there is no problem of bacteria breeding after being placed for a long time. The quality of the cooled boiled water made is more hygienic and safe, and users can drink it more safely and reassuringly.

[0048] It is understood that water pumps are provided on the hot water inlet pipe 333, the first hot water outlet pipe, the second hot water outlet pipe, the cold water inlet pipe 331, the first cold water outlet pipe 332, and the second cold water outlet pipe, and under the action of the water pumps, water circulates in each pipeline to form a water circuit system, which will not be elaborated in detail here.

[0049] Preferably, the cooling water pipe 334 is arranged in an S shape. With such a setting, the flow path of the hot water in the cooling water pipe 334 can be extended, enabling it to fully exchange heat with the cold water in the cold water tank 32 to achieve cooling, and thus ensuring that the cold water coming out has a relatively low water temperature.

[0050] Among them, in order to further improve the cooling effect of the cold water tank 32, a first evaporation pipe 38 is further provided in the cold water tank 32, and a first flow channel for the refrigerant to flow is formed in the first evaporation pipe 38; preferably, the first evaporation pipe 38 is in a U shape. Thus, when the refrigerant flows through the first evaporation pipe 38, the refrigerant can absorb heat to cool the cold water in the cold water tank 32 again, thereby ensuring that the cold water in the cold water tank 32 always remains at a relatively low temperature.

[0051] It should be noted that in other embodiments, the first evaporation pipe 38 may not be provided in the cold water tank 32. When the water temperature in the cold water tank 32 rises, the water can be pumped back into the ice making box 31 through the first cold water outlet pipe 332 for refrigeration, and then flow back into the cold water tank 32 through the cold water inlet pipe 331, so as to ensure that the water temperature in the cold water tank 32 always remains at a relatively low temperature, and there is no limitation here.

[0052] Refer to Figure 2 and Figure 5-6 , it further includes a compressor 4, a condenser 5, a dryer 6, and a capillary tube 7 provided in the machine shell 1. The ice making module 3 further includes an evaporator 37 provided in the ice making box 31. The compressor 4 and the condenser 5, the condenser 5 and the dryer 6, the dryer and the capillary tube 7, the capillary tube 7 and the evaporator 37, the evaporator 37 and the first evaporation pipe 38, and the first evaporation pipe 38 and the compressor 4 are all connected through pipelines for the refrigerant to flow.

[0053] Thus, after injecting refrigerant into the compressor 4, the low-temperature and low-pressure gaseous refrigerant can be compressed into a high-temperature and high-pressure gaseous refrigerant under the action of the compressor 4. Subsequently, the high-temperature and high-pressure gaseous refrigerant enters the condenser 5, and under the action of the condenser 5, the high-temperature and high-pressure gaseous refrigerant is changed into a low-temperature and high-pressure liquid refrigerant. Then, it enters the dryer 6 for filtration and drying and then enters the capillary tube 7. The capillary tube 7 changes the low-temperature and high-pressure liquid refrigerant into a low-temperature and low-pressure liquid refrigerant and enters the evaporator 37 and the first evaporation tube 38. The low-temperature and low-pressure liquid refrigerant evaporates and absorbs heat to become a high-temperature and low-pressure gaseous refrigerant. Subsequently, the refrigerant returns to the front of the compressor 4 through the pipeline. The gaseous refrigerant continuously cools down and forms a low-temperature and low-pressure gaseous refrigerant. Then, the refrigerant flows back into the compressor 4 again, and so on in a cycle.

[0054] Specifically, the evaporator 37 includes a second evaporation tube 371 and a plurality of columns 372 arranged at intervals along the axis direction of the second evaporation tube 371. The inside of the second evaporation tube 371 and the inside of the plurality of columns 372 are all connected and form a second flow channel for the refrigerant to flow; the outlet end of the second evaporation tube 371 is connected to the inlet end of the first evaporation tube 38 through a pipeline; the inlet end of the second evaporation tube 371 is provided with a first refrigerant inlet tube 3711 and a second refrigerant inlet tube 3712. The first refrigerant inlet tube 3711 is connected to the output end of the capillary tube 7. The first refrigerant inlet tube 3711 introduces the low-temperature and low-pressure liquid refrigerant into the inside of the second evaporation tube 371 to achieve refrigeration or ice making; the second refrigerant inlet tube 3712 is connected to the output end of the compressor 4. The second refrigerant inlet tube 3712 introduces the high-temperature and high-pressure gaseous refrigerant into the inside of the second evaporation tube 371 to achieve ice defrosting.

[0055] Among them, referring to Figure 2 , a one-way valve 8 is further provided at the output end of the compressor 4. The one-way valve 8 is connected to the second refrigerant inlet tube 3712 through a pipeline; when ice defrosting is required, by opening the one-way valve 8, the high-temperature and high-pressure gaseous refrigerant compressed by the compressor 4 can enter the second evaporation tube 371 through the second refrigerant inlet tube 3712 to achieve ice defrosting.

[0056] In addition, the ice making module 3 further includes an ice storage bucket 34. The ice making box 31 is rotatably arranged at the inner top of the ice storage bucket 34; among them, a driving device 36 is further included which is drivingly connected to the ice making box 31. The driving device 36 drives the ice making box 31 to rotate to drop the ice cubes into the ice storage bucket 34. Preferably, the driving device 36 is a driving motor, and the output shaft of the driving motor is connected to one end of the ice making box 31 to achieve transmission.

[0057] Thus, when ice making is required, first, a low-temperature and low-pressure liquid refrigerant is introduced into the second evaporation tube 371 through the first refrigerant inlet pipe 3711 to cool the water until it freezes into ice cubes, and the ice making is completed. When ice removal is required, a high-temperature and high-pressure gaseous refrigerant can be introduced into the second evaporation tube 371 through the second refrigerant inlet pipe 3712 to achieve ice removal. Finally, under the action of the driving device 36, the ice making box 31 is driven to turn over so that the ice cubes fall into the ice storage bucket 34.

[0058] Among them, a separable ice storage box 341 is also provided in the ice storage bucket 34, and the ice storage box 341 can be used to receive the ice cubes that fall from the turning over of the ice making box 31. Preferably, an opening communicating with the ice storage box 341 is provided on the side of the ice storage bucket 34, and the user can take out or put in the ice storage box 341 through this opening, which is convenient to operate.

[0059] In addition, it should be noted that when ice removal is required, the excess residual water in the ice making box 31 can be pumped back into the cold water tank 32 through the cold water inlet pipe 331 to avoid remaining in the ice making box 31 and causing secondary pollution. At the same time, the ice cubes removed when the ice making box 31 is turned over for ice removal are also relatively clean.

[0060] Furthermore, the ice making module 3 further includes a sealing cover 35 covering the top of the ice storage bucket 34, and the sealing cover 35 seals and shields the ice making box 31. In addition, the cold water tank 32 is also of a sealed box structure. Thus, the ice making box 31, the cold water inlet pipe 331, the cold water tank 32, and the first cold water outlet pipe 332 are sequentially connected in a closed loop to form a closed water circulation system, which can avoid contact with the outside world and cause pollution, thereby making the water quality more hygienic and clean, and the user drinking more safely.

[0061] In addition, the ice making module 3 further includes a first heat insulation sleeve 391 and a second heat insulation sleeve 392. The first heat insulation sleeve 391 is sleeved outside the ice storage bucket 34 to achieve heat insulation and heat preservation, and the second heat insulation sleeve 392 is sleeved outside the cold water tank 32 to achieve heat insulation and heat preservation, thereby ensuring the refrigeration effect of the ice storage bucket 34 and the cold water tank 32.

[0062] Refer to Figure 7 , the working process of the thermos of the present utility model is as follows:

[0063] When hot water needs to be output, the thermos flask 2 can directly output hot water to the water outlet 11 through the first hot water outlet pipe; when cold water needs to be output, the thermos flask 2 can first inject hot water into the ice-making box 31 through the hot water inlet pipe. After the hot water in the ice-making box 31 cools to a specified temperature, the cold water is pumped back into the cold water tank 32 through the cold water inlet pipe 331. Subsequently, the cold water tank 32 outputs cold water to the water outlet 11 through the second cold water outlet pipe; when warm boiled water needs to be output, the hot water in the thermos flask 2 can be output through the first hot water outlet pipe and the second hot water outlet pipe respectively. When the hot water output by the second hot water outlet pipe flows through the cooling water pipe 334, it can exchange heat with the cold water in the cold water tank 32 and be cooled into cold water. Subsequently, the cold water is mixed with the hot water output by the first hot water outlet pipe and modulated into warm boiled water at a specified temperature and then output.

[0064] When ice needs to be made, the thermos flask 2 injects hot water into the ice-making box 31 through the hot water inlet pipe. After the hot water in the ice-making box 31 reaches a specified capacity, it starts to cool. When it cools to a specified temperature, the cold water is pumped back into the cold water tank 32 through the cold water inlet pipe 331 for secondary cooling. After the cold water in the cold water tank 32 reaches a specified capacity, it is pumped back into the ice-making box 31 through the first cold water outlet pipe 332 and starts to make ice; when the ice-making is completed, the cold water in the ice-making box 31 is pumped back into the cold water tank 32 through the cold water inlet pipe 331. Until there is no excess residual water in the ice-making box 31, the ice-making box 31 operates to make the ice cubes fall into the ice storage bucket 34 to achieve ice output.

[0065] Embodiment 2

[0066] Refer to Figure 8 In this embodiment, the difference between the ice-making module 3 in the thermos flask and that in Embodiment 1 is that the water outlet end of the hot water inlet pipe in this embodiment is communicated with the cold water tank 32.

[0067] Thus, after the hot water in the thermos flask 2 is injected into the cold water tank 32 through the hot water inlet pipe, it cools after reaching the specified capacity. After cooling to the specified temperature, the cold water is pumped back into the ice-making box 31 through the first cold water outlet pipe 332 for secondary cooling. After the water in the ice-making box 31 cools to the specified temperature, the water is pumped back into the cold water tank 32 through the cold water inlet pipe 331, and so on in a cycle.

[0068] Refer to Figure 9 The working process of the thermos flask in this embodiment is as follows:

[0069] The way to output hot water and cooled boiled water is the same as that in the first embodiment, which will not be elaborated here; when cold water needs to be output, the hot water in the thermos bottle 2 is injected into the cold water tank 32 through the hot water inlet pipe, and after reaching the specified capacity, it is cooled. After being cooled to the specified temperature, the cold water is pumped back into the ice making box 31 through the first cold water outlet pipe 332 for secondary cooling. After the water in the ice making box 31 is cooled to the specified temperature, it is pumped back into the cold water tank 32 through the cold water inlet pipe 331. Subsequently, the cold water tank 32 outputs cold water to the water outlet 11 through the second cold water outlet pipe.

[0070] When ice needs to be made, the hot water in the thermos bottle 2 is injected into the cold water tank 32 through the hot water inlet pipe, and after reaching the specified capacity, it is cooled. After being cooled to the specified temperature, the cold water is pumped back into the ice making box 31 through the first cold water outlet pipe 332 for secondary cooling. After the water in the ice making box 31 is cooled to the specified temperature, it is pumped back into the cold water tank 32 through the cold water inlet pipe 331. After the water in the cold water tank 32 reaches the specified capacity, the water is pumped back into the ice making box 31 through the first cold water outlet pipe 332 again and ice making starts; when the ice making is completed, the way to output ice is the same as that in the first embodiment, so it will not be elaborated here.

[0071] In summary, for a thermos bottle provided by the present utility model that can ensure the hygienic quality of cooled boiled water, since cold water in the cold water tank 32 is not used for modulation, there is no problem of bacteria breeding after being placed for a long time. The quality of the cooled boiled water made is more hygienic and safe, and users can drink it more safely and reassuringly.
