[0026] See also Figure 1-Figure 2The utility model provides a heat exchange charging chamber structure capable of improving heating efficiency, comprising a box body 1 and a heat exchange coil 2. A storage cavity is provided in the box body 1, and the heat exchange coil 2 is provided in the storage cavity. The water inlet and the water outlet of the heat exchange coil 2 both pass through the storage cavity. The storage cavity is provided with a high-energy heat storage medium for heat transfer to the heat exchange coil 2 and a heater 3 for heating the high-energy heat storage medium. The heat exchange coil 2 is used for the flow of clean water of the water purification equipment. Since the heat exchange coil 2 is provided in the storage cavity, the water flow can transfer heat with the high-energy heat storage medium when passing through the heat exchange coil 2. After the heater 3 heats the high-energy heat storage medium, the high-energy heat storage medium in the storage cavity has a higher temperature. Under the action of heat transfer, the water in the heat exchange coil 2 is preheated, and the heating efficiency of the water in the heat exchange coil 2 is improved, thereby accelerating the flow rate of the hot water outlet.

[0027] Furthermore, the heat exchange coil 2 is provided with a water inlet 21, a water outlet 22 and a connecting pipe 23. The water inlet 21 and the water outlet 22 are arranged outside the box body 1, and the connecting pipe 23 is arranged in the storage cavity. One end of the connecting pipe 23 is connected to the water inlet 21, and the other end is connected to the water outlet 22, so that the water inlet 21 and the water outlet 22 are connected. After the connecting pipe 23 extends into the bottom of the storage cavity, it spirals upward. After the water flows through the water inlet 21, it enters the connecting pipe 23, and after reaching the bottom of the storage cavity along the connecting pipe 23, it flows upward in a spiral. In the process, it exchanges heat with the high-energy heat storage medium, heats the clean water in the connecting pipe 23 in the form of heat transfer, and the clean water heated by heat transfer flows out from the water outlet 22.

[0028] Further, the connecting pipe 23 includes a first vertical pipe 231, a second vertical pipe 232 and a spiral pipe, one end of the first vertical pipe 231 is connected to the water inlet 21, the other end extends into the bottom of the storage cavity and is connected to one end of the spiral pipe, the other end of the spiral pipe spirals upward from the bottom of the storage cavity to the top of the storage cavity and is connected to one end of the second vertical pipe 232, and the other end of the second vertical pipe 232 passes through the box body 1 and is connected to the water outlet 22. The first vertical pipe 231 is used to guide the water flow into the bottom of the storage cavity, and the second vertical pipe 232 is used to guide the water flow out of the storage cavity and out of the water outlet 22, and then gradually flows upward from the bottom of the storage cavity. On the one hand, since the temperature at the bottom of the storage chamber is lower than the temperature at the top, the water flow in the connecting pipe 23 spirals upward from the low-temperature zone at the bottom to the high-temperature zone at the top. The clean water is heated at the bottom of the storage chamber and then further heated at the top of the storage chamber. A large temperature difference can be maintained between the high-energy heat storage medium and the clean water throughout the process, thereby improving the efficiency of heat transfer and achieving a better heat exchange effect. On the other hand, the spiral pipe design can increase the heat transfer time between the clean water and the high-energy heat storage medium. After the water flows into the bottom of the storage chamber along the first vertical pipe 231, it spirals upward along the spiral pipe, thereby increasing the residence time of the clean water in the storage chamber and enabling sufficient heat transfer with the high-energy heat storage medium, thereby improving the preheating effect and saving space.

[0029] Further, the spiral pipe includes a first horizontal pipe 233, a second horizontal pipe 234 and at least one spiral pipe 235. The spiral pipe 235 is arranged between the first horizontal pipe 233 and the second horizontal pipe 234. One end of the first horizontal pipe 233 is connected to the first vertical pipe 231, and the other end is connected to one end of the spiral pipe 235. The other end of the spiral pipe 235 is connected to one end of the second horizontal pipe 234, and the other end of the second horizontal pipe 234 is connected to the second vertical pipe 232. A plurality of spiral pipes 235 connected to each other are arranged between the first horizontal pipe 233 and the second horizontal pipe 234. After the plurality of spiral pipes 235 are connected, a spiral pipe is formed, and the two ends are respectively connected to the first horizontal pipe 233 and the second horizontal pipe 234.

[0030] Furthermore, the box body 1 includes a box body 11, an upper end cover 12 of the energy storage bin and a lower end cover 13 of the energy storage bin, and the upper end cover 12 of the energy storage bin and the lower end cover 13 of the energy storage bin are respectively covered on the top and bottom of the box body 11 to form a storage cavity. The upper end cover 12 of the energy storage bin and the lower end cover 13 of the energy storage bin are both detachable structures, and the upper end cover 12 of the energy storage bin and the lower end cover 13 of the energy storage bin are both sealed and connected to the box body 11 to prevent the high-energy heat storage medium from overflowing.

[0031] Furthermore, the upper end cover 12 of the charging chamber is provided with a first through hole for the first vertical pipe 231 to pass through and a second through hole for the second vertical pipe 232 to pass through. Preferably, the first vertical pipe 231 is sealedly connected to the first through hole, and the second vertical pipe 232 is also sealedly connected to the second through hole, so that the heat of the high-energy heat storage medium will not overflow from the gap between the outer wall of the first vertical pipe 231 and the hole wall of the first through hole or from the gap between the outer wall of the second vertical pipe 232 and the hole wall of the second through hole.

[0032] Furthermore, a temperature detection device 4 is provided on the upper end cover 12 of the charging chamber for detecting the temperature of the high-energy heat storage medium. The temperature detection device 4 may be a temperature sensor, the probe of which extends into the interior of the storage cavity and contacts the high-energy heat storage medium, and can monitor the temperature of the high-energy heat storage medium in real time. When the temperature of the high-energy heat storage medium is lower than a preset temperature, the heater is turned on to heat the high-energy heat storage medium.

[0033] Furthermore, a pressure relief port 15 is provided on the upper end cover 12 of the charging chamber, and the pressure relief port 15 is connected to the storage chamber. The pressure relief port 15 is used to connect a pressure relief valve to prevent the internal pressure of the storage chamber from being too high, so that the internal pressure of the storage chamber is always in a balanced state, ensuring that the heat exchange charging chamber structure can operate stably.

[0034] Furthermore, the high-energy heat storage medium is water or calcium chloride solution, so that the high-energy heat storage medium has a good heat transfer effect, and the heat exchange coil 2 is made of stainless steel material, which will not rust or corrode in water or calcium chloride solution.

[0035] Furthermore, a heat preservation layer 14 is provided on the outside of the box body 1, and the heat preservation layer 14 wraps the box body 11. The heat preservation layer 14 is made of cotton material, has a heat preservation effect, and can reduce the heat loss of the high-energy heat storage medium. In some other embodiments, a heat preservation layer 14 is also provided on the bottom wall of the lower end cover 13 of the charging bin, and the heat preservation layer 14 wraps the outer side wall and the outer bottom wall of the box body 1 at the same time to achieve a better heat preservation effect.
