Description

Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a warm water machine with rapid heating, rapid cooling and precise temperature adjustment. Background Art

[0002] At present, there are three common ways of drinking water in kindergartens: (1) boiling water in a centralized manner, cooling it, and then distributing it to each class; (2) replacing the temperature control of the water dispenser to fix the temperature at around 40°C for direct drinking by children in each class; (3) combining hot tank heating with a heat exchanger to provide warm water through heat exchange after the hot tank water is boiled. People have tried to improve the above schemes, and adjustable temperature instant hot water dispensers have emerged. For example, Patent No. CN202022580933.6 discloses "A quick-heating and quick-cooling warm water dispenser for young children".

[0003] This patent mixes the cooled boiled water with the boiled water at the output end, and controls the amount of boiled water added by adjusting the opening and closing degree of the electromagnetic flow valve, so as to achieve the effect of rapid temperature adjustment at the water outlet. However, this technical solution still has the following deficiencies:

[0004] (1) The boiled water and cold boiled water flowing to the outlet solenoid valve cannot be quickly and fully mixed, and the water temperature will fluctuate when the water is discharged;

[0005] (2) The higher the outlet water temperature is set, the more boiling water is added, the harder it is to control the temperature, and the greater the temperature difference.

[0006] (3) The raw water inlet temperature is different in different seasons, and the temperature of the boiled water after heat transfer is different. If boiled water is added in the same way in winter and summer, it is conceivable that there will be differences in the temperature difference of the outlet water.

[0007] (4) In the present invention, all water needs to be boiled. The longer the boiling time is, the higher the temperature inside the machine will be. The temperature of the serpentine coil will also be higher and higher, thus affecting the efficiency of heat transfer. The water temperature of the subsequent users will be higher than that of the previous users.

[0008] Inherited from you, needs further improvement. Utility Model Content

[0039] The water inlet pipeline 10 can pass water through the first heat exchanger 20 and send it to the instant heating component 30; the instant heating component 30 can heat the water to form boiling water and send it to the boiling water box 40;

[0040] The water outlet of the hot water box 40 includes a first water channel 50 and a second water channel 60; the first water channel 50 is provided with a hot water pump 51, which is directly connected to the heat preservation tank 70; the second water channel 60 is provided with a warm water pump 61; the second water channel 60 first passes through the first heat exchanger 20, and then delivers water to the heat preservation tank 70;

[0041] The heat preservation tank 70 is provided with a temperature sensing probe 71 and a heat preservation heating component 72 ; the heat preservation tank 70 is connected to a water outlet pipeline 80 .

[0042] In the utility model, water is heated and boiled by the instant heating component 30 to form boiled water and buffered in the boiled water box 40. The boiled water in the boiled water box 40 is output through two water paths; the boiled water in the first water path 50 is directly transferred to the insulation tank 70, and the boiled water in the second water path 60 first passes through the second heat exchanger to exchange heat with the cold water in the water inlet pipe 10, and quickly cools down to form cold boiled water, and then is sent to the insulation tank 70; the insulation tank 70 fully mixes the water in the two water paths to form warm boiled water; by changing the flow rate of the water pumps of the first water path 50 and the second water path 60, the water temperature of the mixed warm water in the insulation tank can be quickly changed; and through the temperature sensing probe 71 and the insulation heating component 72 of the insulation tank 70, the temperature of the warm boiled water in the insulation tank 70 can be quickly adjusted and sent out through the water outlet pipe 80. The utility model has the following advantages:

[0043] (1) Warm boiled water is mixed and stored in the heat preservation tank 70, and the water temperature is detected and heated before the water is discharged; and the flow rates of the first water channel 50 and the second water channel 60 are adjusted synchronously, so that the outlet water temperature is stable, thereby avoiding the situation where the child is scalded due to unstable water temperature;

[0044] (2) By adjusting the temperature sensing probe 71 and the heat preservation and heating assembly 72 of the heat preservation tank 70, the outlet water temperature of the heat preservation tank 70 is stable, and the problem of unstable water temperature and large seasonal differences due to different inlet water temperatures caused by different seasons will not occur;

[0045] (3) The water in the first water channel 50 and the second water channel 60 are both delivered from the output end of the water box 40. Both the cold water and the boiled water are boiled to ensure the safety and cleanliness of the drinking water.

[0046] The utility model can accurately adjust the temperature according to different output water temperatures, for example, the required water temperature is 40°C, 45°C, 46°C, 50°C, 60°C and other water outlet temperatures.

[0047] In the present invention, it is not limited to adopting the method of the heat preservation tank 70 to ensure that the water temperature is more stable and accurate. The instant heating component 30 and the heat exchanger can be operated to provide boiled water, and then the boiled water pump 51 is connected to the heat preservation heating component 72.

[0048] The utility model not only solves the problem of safe water use, but also avoids the later failure caused by the frequent opening and closing of the electromagnetic flow valve and the abnormal noise caused by the frequent opening and closing of the electromagnetic valve during the use of the equipment. Furthermore, the operation of the main parts is different from the conventional parts used in daily life, and the design principle is more scientific and reasonable, which can ensure stable operation.

[0050] Furthermore, the first heat exchanger 20 is wound around the outside of the instant heating component 30. By utilizing the outer space of the instant heating component 30 to wind and arrange the first heat exchanger 20 of the nested tube structure, space utilization can be saved, and at the same time, the heat overflowing from the instant heating component 30 can be absorbed by the water inlet pipeline 10, and the effect of preheating the water inlet pipeline 10 by further utilizing the structure of the first heat exchanger 20, the water temperature of the water entering the instant heating component 30 is higher, the power required for boiling water is reduced, and the heating efficiency of the instant heating component 30 is improved.

When the machine is turned on for the first time, the warm water machine enters the boiling water sterilization mode, the water inlet pipe 10 enters the water and forms boiling water in the water box 40, and when the water level of the water box 40 reaches the set value, the water pump of the water inlet pipe 10 and the water pump of the water outlet pipe 80 are closed; the disinfection valve 91 is opened, the boiling water pump 51 of the first water channel 50 and the warm water pump 61 of the second water channel 60 are turned on, so that the boiling water in the water box 40 circulates and disinfects in the water box 40, the first water channel 50, the second water channel 60, the third water channel 90 and the heat preservation tank 70; after the set time is reached, it is discharged through the water outlet pipe 80.

[0052] In this embodiment, the boiled water box 40 and the heat preservation tank 70 are provided with water level sensors 42 to avoid safety risks caused by excessively high water levels in the boiled water box 40 and the heat preservation tank 70.

[0053] In this embodiment, the boiling water box 40 is provided with a temperature sensor 41 to monitor the temperature of the boiling water in the boiling water box 40 in real time.

[0054] Furthermore, the first water channel 50 and the second water channel 60 are respectively provided with temperature sensors 41 to monitor the water flow temperature of the first water channel 50 and the second water channel 60 respectively, and adjust the flow rate of the first water channel 50 and the second water channel 60 according to the required temperature of the insulation tank 70.

[0055] In this embodiment, the water inlet pipeline 10 is provided with a water inlet valve 11 , a water inlet pump 12 and a flow meter 13 .

[0056] Furthermore, the water inlet pipeline 10 is provided with a buffer water tank 14. The buffer water tank 14 can buffer and store a certain amount of water, and then supply water to the instant heating component 30 through the water inlet pipeline 10, so that the water flow supply is more stable.

In the utility model, a plurality of water outlet pipes 80 are provided; each water outlet pipe 80 is provided with a water outlet valve 81 and a water outlet pump 82, which can control the water outlet operation of the independent water outlet taps separately.
