a first three-way valve 106 installed on a water pipe (i.e., the third water passage 13) communicating between the first heating body 104 and the water outlet 105, for controlling the flow of hot or warm water to the water outlet 105; the hot water flowing out of first heating body 104 is returned to inner pipe 107 through a first return pipe (i.e., fourth water passage 14), and is heat-exchanged with the water in outer pipe 108 to form warm water, which is then passed to first three-way valve 106 through a second return pipe (i.e., fifth water passage 15).
Thus, the design of the water path of the boiled water is as follows: a water tank, a water pump, a heat exchange tube outer tube, a first heating body, a first three-way valve and a water outlet; the water path formed is shown in figure 1: first waterway 11-second waterway 12-third waterway 13.
The waterway design of warm water is as follows: first heater-first three-way valve-heat exchange tube-inner tube-water outlet. The water path formed is shown in figure 1: fourth waterway 14-fifth waterway 15.
Because the first three-way valve is arranged, the waterway of warm water and boiled water is redesigned, and therefore the same water outlet can discharge hot water or warm water according to the requirement.
In addition, a further embodiment may be provided, in which a second heating body 109 is connected to the second return pipe (i.e., the fifth water path 15), and a first temperature sensor 110 is disposed at a water inlet end of the second heating body 109. Thus, the first temperature sensor 110 is arranged on the fifth water path 15 to sense the water temperature, and when the difference exists between the water temperature and the water taking requirement, the second heating body 109 can generate heating power for the water on the fifth water path 15, so that the water temperature reaches the required water taking temperature, and the water flow reaches the water outlet. This is not done in the prior art.
As a further specific embodiment, a second temperature sensor 111 is provided at the water inlet end of the first heating body 104, and a third temperature sensor 112 is provided at the water outlet end of the first heating body 104.

TDS (total DISSOLVED solids) is the total solids content DISSOLVED in water, and a TDS meter is a meter designed for the TDS meter, and the TDS can be used for seeing the ppm value of inorganic matters or organic matters in the water. The Total Dissolved Solids (TDS) value in the water is detected, i.e. the total amount of various organic or inorganic substances dissolved in the water is detected. The limited amount of soluble total solids (TDS) of drinking tap water in the national standard GB5749-2006 sanitary standard for drinking water requires: total soluble solids < 1000mg/L (1 mg/L-1 ppm).
A flow meter 114 is provided at the water inlet end of the outer tube 108. The temperature reduction amplitude of the boiled water passing through the heat exchanger is related to the flow, so the temperature of the warm water can be indirectly controlled by controlling the flow.

The working process of the heat conversion water dispenser of the embodiment is as follows:
1. water in the water tank reaches the outer pipe of the heat converter through the action of the water suction pump through the first water path 11, reaches the first heating body through the second water path 12 and is heated, and the boiled water state is achieved.
2. And judging according to the required drinking temperature, when water needs to be taken as boiled water, the valve corresponding to the first three-way valve is opened at the moment, and the boiled water in the heating body reaches the water outlet through the third water channel 13.
3. When the boiled water with other temperature needs to be taken, the three-way valve corresponding to the valve is opened, the boiled water reaches the inner pipe of the heat converter through the fourth water channel 14, and the boiled water is subjected to heat conversion with the outer pipe low-temperature water to reach the required temperature and flows out through the fifth water channel 15.
4. The fifth water path 15 is provided with a first temperature sensor for sensing the water temperature, and when the water temperature is different from the water taking requirement, the second heating body can generate heating power for the water on the fifth water path 15, so that the water temperature reaches the required water taking temperature, and the water flow reaches the water outlet.
Example 2
Referring to embodiment 1, the hot water and boiled water in the hot water conversion water dispenser have the same waterway design, and different from embodiment 1, referring to fig. 2, the hot water conversion water dispenser further includes a small water tank 115, a water outlet of the small water tank 115 is communicated with the water pump 102 through a seventh waterway 17, a second three-way valve 116 is disposed on a second return pipe (i.e., a fifth waterway 15), a valve port of the second three-way valve 116 is communicated with a water inlet of the small water tank 115, and the second three-way valve 116 is used for controlling residual water in the inner pipe to flow back to the small water tank through a sixth waterway 16. Therefore, the technical problem that the initial water temperature of the water outlet is influenced because the temperature of the residual water in the inner pipe of the heat exchanger is not the required temperature for taking water is solved.
The working process of the heat conversion water dispenser of the embodiment is as follows:
1. water in the water tank reaches the outer pipe of the heat converter through the action of the water suction pump through the first water path 11, reaches the first heating body through the second water path 12 and is heated, and the boiled water state is achieved.
2. And judging according to the required drinking temperature, when water needs to be taken as boiled water, the valve corresponding to the first three-way valve is opened at the moment, and the boiled water in the heating body reaches the water outlet through the third water channel 13.
3. When water needs to be taken into the water heater at other temperatures, the first three-way valve opens the other valve port, the boiled water enters the inner pipe of the heat converter from the fourth water channel 14, is subjected to heat conversion with the outer pipe low-temperature water, reaches the required temperature and flows out through the fifth water channel 15, at the moment, the valve of the three-way valve 2 corresponding to the water outlet is opened, and the water flow reaches the water outlet.
4. The inner pipe has residual water in each time of taking water, but the temperature is not necessarily required for taking water in this time, and therefore the initial water temperature of the water outlet is affected. Therefore, before the whole machine is set to take water each time, the interior of the whole machine is adjusted, and water in the inner pipe flows to the sixth water channel 16 through the other valve port of the second three-way valve and reaches the small water tank; the water in the small water tank is mixed with the first water channel 11 through the seventh water channel 17; and normally fetching water after the adjustment is finished.
Example 3
Referring to example 1, in addition to example 1, referring to fig. 3, the inner tube 107 of the heat exchanger has a straight-tube spiral structure. Namely, the inner pipe wall of the straight cylinder is provided with a spiral structure. Compared with the heat conversion inner tube structure which is normally used in the prior art, the heat conversion inner tube structure is a straight tube light wall structure; the inner tube structure of the new design of the embodiment is a straight-tube spiral structure; the straight-barrel spiral structure can increase the surface area of an object, so that the cooling area of boiled water in the inner pipe is enlarged, and the cooling efficiency is accelerated.
Example 4
Referring to example 1, the inner tube 107 and the outer tube 108 of the heat exchanger are both of a spiral structure in addition to example 1. And form a double helix structure. The double-spiral structure can also increase the surface area of an object, so that the cooling area of the boiled water in the inner pipe is enlarged, and the cooling efficiency is accelerated.
Example 5
Referring to embodiment 1, in embodiment 1, a second heating body 109 is connected to the second return pipe (i.e., the fifth water channel 15), and a first temperature sensor 110 is disposed at a water inlet end of the second heating body 109. Thus, the first temperature sensor 110 is arranged on the fifth water path 15 to sense the water temperature, and when the difference exists between the water temperature and the water taking requirement, the second heating body 109 can generate heating power for the water on the fifth water path 15, so that the water temperature reaches the required water taking temperature, and the water flow reaches the water outlet.
Unlike embodiment 1, this embodiment does not communicate the second heating body 109 to the second return pipe (i.e., the fifth water path 15), but is provided with a third heating body 117 in the water path (the third water path 13) between the water outlet and the first three-way valve. In this way, on the one hand, it is also possible that when there is a difference between the water temperature and the demand for water intake, the third heating element 116 will generate heating power for the water flowing from the fifth water path 15 to the third water path 13, so that the water temperature reaches the required water intake temperature and the water flow reaches the water outlet. On the other hand, when the temperature of the hot water is insufficient, the third heating body can continue to heat. When the temperature of the hot water is sufficient, the third heating body is used as a transition member.
It should be noted that the water tank may also be referred to as a water storage device or a water delivery device, and the flow meter may be referred to as a meter, which should not affect the protection scope of the present invention.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
