As shown in fig. 1 to 5, the present utility model provides a preferred embodiment of a zero raw water drinking apparatus.
A zero raw water drinking device, the zero raw water drinking device comprises a first water inlet pipe 310, a first water outlet pipe 320, a hot water pipe 330, a warm water pipe 340, a double pipe heat exchanger 100 and a heating mechanism 200, wherein the double pipe heat exchanger 100 comprises an inner pipe 12 and an outer pipe 11, the outer pipe 11 is sleeved outside the inner pipe 12 and forms a first water pipeline 110 with the inner pipe 12, a second water pipeline 120 is formed in the inner pipe 12, the double pipe heat exchanger 100 further comprises a first water inlet 131 and a first water outlet 132 which are communicated with the first water pipeline 110, and a second water inlet 133 and a second water outlet 134 which are communicated with the second water pipeline 120; wherein the first water inlet pipe 310 is communicated with the first water inlet 131, the first water outlet pipe 320 is respectively communicated with the first water outlet 132 and the heating mechanism 200, the hot water pipe 330 is respectively communicated with the second water inlet 133 and the heating mechanism 200, and the warm water pipe 340 is communicated with the second water outlet 134; the length of the inner pipe 12 or the outer pipe 11 is between 2m and 3.2m, and the flow ratio of the first water passing pipe 110 to the second water passing pipe 120 is between 0.8 and 1.2.
Specifically, external raw water enters through the first water inlet pipe 310, enters the first water pipeline 110 of the double pipe heat exchanger 100 through the first water inlet 131, achieves primary temperature rise through heat exchange, then flows into the heating mechanism 200 through the first water outlet 132 and the first water outlet pipe 320, and achieves secondary temperature rise through the heating mechanism 200 to form hot water; the hot water re-enters the double pipe heat exchanger 100 through the hot water pipe 330, enters the second water passing pipe 120 of the double pipe heat exchanger 100 through the second water inlet 133, and the hot water in the second water passing pipe 120 transfers heat to the raw water in the first water passing pipe 110, thereby realizing the cooling of the hot water until warm water is formed and enters the warm water pipe 340 from the second water outlet 134, and the warm water is output; finally, the zero raw water drinking device realizes warm water supply and hot water supply.
Inside the double pipe heat exchanger 100, heat is exchanged between the boiled water and the raw water, and heat is transferred from the boiled water to the raw water, so that the temperature of the raw water increases and the temperature of the boiled water decreases. When the heat exchange is finished, according to the temperature of raw water before entering the double pipe heat exchanger 100, such as about 25 ℃, the raw water temperature at the first water outlet 132 can reach 75 ℃ to 85 ℃, and if the raw water temperature is changed greatly, the raw water temperature at the first water outlet 132 is also changed greatly; and the temperature of the flow path of the boiled water from the second water outlet 134 can reach about 40 to 50 ℃. These can also be controlled more precisely to a preset temperature, for example, to 45 c, depending on the setting of the length of the inner tube 12 or the outer tube 11 or the adjustment of the flow ratio.
Wherein the length of the inner tube 12 or the outer tube 11 is at a suitable length in order to save more space. The flow rate of the first water pipe 110 and the flow rate of the second water pipe 120 are related to the size of the cross-sectional areas of the first water pipe 110 and the second water pipe 120, and also to the flow rates of the first water pipe 310 and the hot water pipe 330. Normally, the cross-sectional area determines the upper limit of the flow rate, which determines the degree of heat transfer of the heat exchange. The length of the inner pipe 12 or the outer pipe 11 is set to provide enough heat exchange surface area to increase heat transfer efficiency, and to realize more compact structure, and meanwhile, the flow rate ratio is limited to ensure that hot water and cold water are fully contacted in the heat exchanger to control efficient heat exchange.
The length of the inner pipe 12 refers to the length of the second water passing pipe 120, and the length of the outer pipe 11 refers to the length of the first water passing pipe 110, or may be the length of the second water passing pipe 120.

Wherein the outer diameter of the outer tube 11 is between 11mm and 18mm, and the outer diameter of the inner tube 12 is between 7mm and 10mm, to provide a sufficient heat exchange surface area and flow capacity, and a size range is relatively small, so that the double pipe heat exchanger 100 can be installed and arranged in a limited space without affecting heat exchange.
The outer tube 11 and the inner tube 12 are preferably cylindrical tubes, the outer diameter of the outer tube 11 is the diameter of the outer tube 11, the outer diameter of the inner tube 12 is the diameter of the inner tube 12, therefore, the circulation area of the first water-passing tube 110 is a tube with an annular cross section, the width of the annular tube is the outer diameter of the outer tube 11 minus the outer diameter of the inner tube 12, the circulation area of the second water-passing tube 120 is a tube with a circular cross section, and the diameter of the circular tube is the outer diameter of the inner tube 12.
And, by keeping the flow ratio of the first water passing pipe 110 and the second water passing pipe 120 close to 1:1, the heat is transferred uniformly in the heat exchange process, so that the hot water and the raw water can be ensured to be in full contact in the double pipe heat exchanger 100, the efficient heat exchange is realized, and the heat utilization rate is improved. Meanwhile, the stable flow reduces the temperature gradient between the hot water and the cold water, promotes the heat transfer and improves the performance of the heat exchanger.
In one embodiment, the double pipe heat exchanger 100 has a serpentine structure, the inner pipe 12 and/or the outer pipe 11 are made of stainless steel, and are made of high-temperature-resistant and corrosion-resistant materials, so that the heat-exchange heat exchanger has higher durability and reliability, higher heat conductivity and higher heat exchange efficiency, ensures long-term stable operation of the heat exchanger, reduces maintenance and replacement frequency, and reduces operation cost. The serpentine double pipe heat exchanger 100 can arrange longer lengths of the inner pipe 12 or the outer pipe 11 in a serpentine manner to achieve a larger heat exchange surface area in a limited space, more efficient use of space, and smaller overall heat exchanger volume.
As shown in fig. 4-7, the present utility model provides a preferred embodiment of a control valve.

As shown in fig. 7 to 9, the present utility model provides a preferred embodiment of a hot water pipe 330.
The hot water pipe 330 includes a second water outlet pipe 331, a third water outlet pipe 332, and a second water inlet pipe 333, the second water outlet pipe 331 is respectively communicated with the third water outlet pipe 332 and the second water inlet pipe 333, and is also communicated with the heating mechanism 200, and the second water inlet pipe 333 is communicated with the second water inlet 133; wherein, the water outlet of the third water outlet pipe 332 has a lower level than the water outlet of the heating mechanism 200.
Specifically, the hot water line heated by the heating mechanism 200 is output from the second water outlet pipe 331 and is split into two paths, and one path of hot water flows out through the third water outlet pipe 332, and of course, a hot water control valve may be disposed at the third water outlet pipe 332, so as to realize control of hot water. The other path is communicated with the second water inlet 133 of the double pipe heat exchanger 100 through the second water inlet pipe 333, and hot water flows into the second water passing pipe 120.
The water outlet of the third water outlet pipe 332 has a lower level than the water outlet of the heating mechanism 200, on one hand, there is a level difference, and hot water automatically flows to the water outlet of the third water outlet pipe 332 under the influence of gravity, without adding an additional pump, and directly receives the hot water; on the other hand, since the water outlet position of the third water outlet pipe 332 is lower, when the heating mechanism 200 stops heating or the water pressure changes, the hot water can be prevented from flowing backward into the heating mechanism 200 or other pipelines, and the safety problem and equipment damage possibly caused by the hot water flowing backward can be reduced.
In one embodiment, the heating mechanism 200 includes a water storage tank 230 and a heating module for heating water flowing into the water storage tank 230, and the water outlet of the water storage tank 230 is communicated with the second water outlet pipe 331.

Wherein the second raw water control valve 420 controls the amount of water injected into the heating tank 210 each time.

Wherein the ultraviolet lamp tube emits ultraviolet radiation to irradiate microorganisms in water to destroy DNA structures thereof, thereby killing them, and the ultraviolet lamp tube needs to be correctly fixed inside the sterilizing tube, and ensures that water flow can be sufficiently exposed to the ultraviolet irradiation region. Ozone disinfection is a method for disinfecting water by utilizing ozone gas, an ozone generator is usually arranged in a disinfection tube, the ozone generator can generate ozone gas and inject the ozone gas into water, and the ozone gas has strong oxidizing property, can kill bacteria, viruses and other microorganisms in the water, and ensures that the ozone gas can uniformly contact with the water. Chemical disinfection is a method of disinfecting water using chemical substances, common chemical disinfectants include chlorine, chlorine dioxide, hydrogen peroxide, etc., which are generally added to water by an injection device or a spraying device, which needs to be properly installed in a disinfection tube and ensure that the chemical disinfectants can be uniformly mixed with the water.
In one embodiment, the zero-water drinking apparatus further includes a filtration mechanism and a pump mechanism in communication with the first inlet tube 310.
