Description

Technical Field

[0001] The utility model relates to the technical field of water dispensers, in particular to a step-by-step warm water drinking device. Background Art

[0002] As people's living standards improve, their demand for drinking water is also increasing. Drinking water dispensers, pipeline dispensers, warm water drinking equipment and other drinking water purification equipment have gradually become essential drinking water facilities in people's daily lives.

[0003] Water dispensers on the market can only provide boiled water or room temperature water. They cannot directly provide warm boiled water. Users need to mix boiled water with room temperature water to make warm water. This is inconvenient to use and the water temperature is difficult to control. It not only wastes time but also leads to a poor user experience. Utility Model Content

[0004] The purpose of the utility model is to provide a step-by-step warm water drinking device, which can at least solve one of the above problems.

[0005] According to one aspect of the present invention, a step-by-step warm boiled water drinking device is provided, comprising a water inlet system, a double-chamber water tank, a heat exchanger and a water outlet system, the double-chamber water tank comprising a water storage tank and a boiled water tank, a heating mechanism being arranged in the boiled water tank, the input end of the water inlet system being connected to a water source, and the output end being connected to the input end of an outer tube of a heat exchanger, the output end of the outer tube of the heat exchanger being connected to the input end of the water storage tank, the output end of the water storage tank being connected to the input end of the boiled water tank, the heating mechanism being used to heat the water in the boiled water tank into boiled water, the output end of the boiled water tank being connected to the input end of an inner tube of the heat exchanger, the water outlet system comprising a boiled water outlet mechanism and a warm boiled water outlet mechanism, the boiled water outlet mechanism being connected to the output end of the boiled water tank for outputting boiled water, the warm boiled water outlet mechanism being connected to the output end of the inner tube of the heat exchanger for outputting warm boiled water.

[0006] In some embodiments, the water inlet system includes a cold water inlet pipeline, along which a purifier, a first solenoid valve, and a regulating valve are sequentially arranged. The output end of the cold water inlet pipeline is connected to the input end of the outer tube of the heat exchanger. This allows for direct connection to a tap water source. The tap water is first filtered by the water purifier to remove impurities and odors before being fed into the heat exchanger.

[0007] In some embodiments, the step-by-step warm water drinking device further includes a water level control system, which includes a water tank water level control mechanism. The water tank water level control mechanism includes a first water level switch mounted on the water tank, which cooperates with a first solenoid valve. Thus, the first water level switch ensures that the hot water in the water tank remains at a minimum level. When the hot water level in the water tank falls below the minimum level, the first water level switch provides feedback to the control device, which then controls the first solenoid valve to open for water replenishment.

[0008] In some embodiments, the water level control system further includes a water level control mechanism for a hot water tank, which includes a second water level switch and a third water level switch mounted on the hot water tank, with the third water level switch mounted higher than the second water level switch. Thus, the second and third water level switches ensure that the water level in the hot water tank remains between a high water level and a low water level.

[0009] In some embodiments, the water level control mechanism for the hot water tank further includes a second hot water inlet pipe, a water inlet conduit, and a first water pump. The water inlet conduit is mounted on the hot water tank, the input end of the second hot water inlet pipe is connected to the output end of the water storage tank, and the output end is connected to the input end of the water inlet conduit. The output end of the water inlet conduit extends to the bottom of the hot water tank. The first water pump cooperates with the second hot water inlet pipe to pump hot water from the water storage tank into the hot water tank. This allows for automatic water replenishment of the hot water tank and can be combined with the heating mechanism to achieve step-by-step heating. That is, after the water in the hot water tank is heated to 100°C by the heating mechanism at the low water level at the bottom of the hot water tank, the first water pump can automatically pump hot water from the water storage tank for replenishment. The newly replenished hot water is heated at the bottom of the hot water tank, while the existing hot water floats to above the original low water level. Repeat the above steps until the water in the water tank reaches the high water level. At this time, the water tank stops replenishing water and stops heating. This technical solution can improve the separation of hot and cold water, alleviate the degree of "yin and yang water", avoid repeated heating, ensure fresh water quality and energy efficiency.

[0010] In some embodiments, the boiling water outlet mechanism includes a first water outlet, a first boiling water output pipeline, a second solenoid valve, and the boiling water outlet. The first water outlet is connected to the boiling water tank, a first end of the first boiling water output pipeline is connected to the first water outlet, and a second end is connected to the boiling water outlet. The second solenoid valve is mounted on the first boiling water output pipeline. Thus, when a user needs boiling water, they can turn on the boiling water button, which opens the second solenoid valve, and the boiling water flows out of the first water outlet, the first boiling water output pipeline, and the boiling water.

[0011] In some embodiments, the step-by-step warm boiled water drinking equipment includes a second water outlet and a second boiled water output pipeline, the second water outlet is connected to the boiled water tank, the first end of the second boiled water output pipeline is connected to the first water outlet, and the second end is connected to the input end of the inner tube of the heat exchanger.

[0012] In some embodiments, the warm water outlet mechanism includes a second water pump, a warm water output pipeline, a third solenoid valve, and a warm water outlet. The first end of the warm water output pipeline is connected to the output end of the inner tube of the heat exchanger, and the second end is connected to the second water pump, the third solenoid valve, and the warm water outlet in sequence. Thus, when a user requests warm water and turns on the warm water button, the second water pump, the third solenoid valve, and the first solenoid valve are simultaneously turned on. The water enters the inner tube of the heat exchanger through the second water output pipeline, where the heat energy is absorbed by the outer tube of the heat exchanger and converted into warm water. The warm water then flows through the warm water output pipeline and out of the warm water outlet.

[0013] In some embodiments, the dual-chamber water tank further includes a first insulation layer and a second insulation layer. The first insulation layer is disposed between the water storage tank and the hot water tank to separate the two, and the second insulation layer is disposed around the outer periphery of the water storage tank and the hot water tank. This provides a good insulation effect.

[0014] In some embodiments, the step-by-step warm boiled water drinking equipment further includes a first overflow pipe and a second overflow pipe, the first overflow pipe being installed on the water tank, the input end of the first overflow pipe extending to the top of the water tank, and the output end extending from the bottom of the water tank, the second overflow pipe being installed on the boiled water tank and located at the top of the boiled water tank.

[0015] Beneficial effects of the utility model:

[0016] Therefore, the water circulation of the drinking water equipment of the present invention is as follows: the boiled water in the boiled water tank enters the inner tube of the heat exchanger, and the cold water enters the outer tube of the heat exchanger through the water inlet system, absorbs the heat energy of the boiled water in the inner tube of the heat exchanger, and thus becomes hot water. The hot water is then input into the water storage tank. The hot water in the water storage tank can be transported to the boiled water tank. After entering the boiled water tank, boiled water is obtained under the action of the heating mechanism. When the user needs to use boiled water, the boiled water is output through the boiled water outlet mechanism. When the user needs to use warm boiled water, the warm boiled water is output through the warm boiled water outlet mechanism.

[0017] Compared with traditional drinking water equipment, this utility model has at least the following advantages:

[0018] 1. The use of a double-chamber water tank can maximize the reuse of resources. The hot water in the water storage tank is formed by the cold water in the outer pipe absorbing the heat of the inner pipe, and the boiling water tank directly heats the hot water into boiling water, forming a circulating water circuit, which is energy-saving and low-cost.

[0019] 2. It is equipped with two water outlet mechanisms: boiling water and warm water, which can meet the needs of users. The warm water is formed by the heat absorbed by the boiling water after it flows through the inner tube. No additional cooling equipment is required, which is energy-saving and low-cost.

The output end of the outer tube of the heat exchanger 3 is connected to the input end of the water storage tank 21, and the output end of the water storage tank 21 is connected to the input end of the boiled water tank 22. The heating mechanism 5 is used to heat the water in the boiled water tank 22 into boiled water. The output end of the boiled water tank 22 is connected to the input end of the inner tube of the heat exchanger 3. The water outlet system 4 includes a boiled water outlet mechanism 41 and a warm boiled water outlet mechanism 42. The boiled water outlet mechanism 41 is connected to the output end of the boiled water tank 22 for outputting boiled water, and the warm boiled water outlet mechanism 42 is connected to the output end of the inner tube of the heat exchanger 3 for outputting warm boiled water.

[0026] The water inlet system 1 includes a cold water inlet pipe 11 and a purifier 12, a first solenoid valve 13, and a regulating valve 14 arranged in sequence along the cold water inlet pipe 11. The output end of the cold water inlet pipe 11 is connected to the input end of the outer pipe of the heat exchanger 3. This allows direct connection to a tap water source. The tap water is first filtered by the water purifier to remove impurities and odors before being input into the heat exchanger 3.

[0027] The step-by-step warm water drinking device also includes a water level control system 6, which includes a water tank water level control mechanism 61. The water tank water level control mechanism 61 includes a first water level switch 611 mounted on the water tank 21. The first water level switch 611 cooperates with the first solenoid valve 13. Thus, the first water level switch 611 ensures that the hot water in the water tank 21 remains at a minimum level. When the hot water level in the water tank 21 falls below the minimum level, the first water level switch 611 provides feedback to the control device, which then controls the first solenoid valve 13 to open for water replenishment.

The first water pump 625 cooperates with the second hot water inlet pipe 623 to pump the hot water in the water storage tank 21 into the boiling water tank 22. In this way, the water tank 22 can be automatically replenished and can be combined with the heating mechanism 5 to achieve step-by-step heating. That is, after the water in the water tank 22 is heated to 100°C by the heating mechanism 5 at the low water level at the bottom of the water tank 22, the water can be automatically pumped from the water storage tank 21 by the first water pump 625 for replenishment. The newly replenished hot water will be heated at the bottom of the water tank 22, while the original boiled water will float to above the original low water level. Repeat the above steps until the boiled water in the water tank 22 reaches the high water level. At this time, the water tank 22 stops replenishing and stops heating. This technical solution can improve the separation of hot and cold water, alleviate the degree of "yin and yang water", avoid repeated heating, ensure fresh water quality, and be energy-efficient.
