[0031] Combine the following Figures 1 to 5 , describing a water heater with multiple levels of pressurized water flow according to an embodiment of the utility model.

[0032] A water heater with multiple levels of pressurized water flow, comprising a heat exchange module 1, a pressurizing module 2 and a control module, wherein the pressurizing module 2 is electrically connected to the control module, and the pressurizing module 2 is used to adjust the instantaneous water flow of the water heater;

[0033] The heat exchange module 1 includes a connecting pipe 11, a heat exchange plate group 12, a water inlet pipe 13 and a water outlet pipe 14. The heat exchange plate group 12 is provided with a plurality of heat exchange pipes. The water inlet pipe 13 is connected to the input end of one of the heat exchange pipes. The two ends of the plurality of connecting pipes 11 are respectively connected to the ends on the same side of two of the heat exchange pipes. The water outlet pipe 14 is connected to the output end of one of the heat exchange pipes.

[0034] The water inlet pipe 13, the water outlet pipe 14, the plurality of connecting pipes 11 and the plurality of heat exchange pipes are connected to form a complete S-shaped water channel, and the S-shaped water channel is used to perform heat exchange on the water flow.

[0035] The multi-speed boosted water flow water heater of the present invention is provided with a booster module 2, which can increase the water flow rate and the water flow rate, which can not only speed up the heat exchange speed of the heat exchange module 1, but also increase the water output of the water heater.

[0036] When the water output of the water heater is small, the user can adjust the instantaneous water output of the water heater in time through the boost module 2 and the control module to ensure that the user can use hot water quickly and improve the user's experience.

[0037] In addition, the present solution is also provided with a heat exchange module 1, which is provided with an S-shaped water channel to increase the contact area between the water flow and the flue gas, thereby improving the heat exchange efficiency of the water heater, further increasing the water output of the water heater, and increasing the hot water supply speed of the water heater, thereby solving the problem of low water pressure and slow heat exchange in traditional water heaters, which results in users being unable to use hot water quickly.

[0038] The boost module 2 includes a display screen 21 and a plurality of boost buttons 22. The display screen 21 is electrically connected to the control module. The plurality of boost buttons 22 are electrically connected to the control module respectively. The boost buttons 22 are used to adjust the instantaneous water flow rate of the water heater.

[0039] The display screen 21 can display other information such as the current water level and temperature of the water heater. There are multiple boost buttons 22, and the multiple boost buttons 22 represent different boost gears of the water heater.

[0040] If the user feels that the current water output is too low during use, the user can press the corresponding boost button 22, and the control module will turn on the boost function according to the boost gear corresponding to the boost button 22, instantly increasing the water volume to make bathing more comfortable. Multiple boost buttons 22 can cooperate with each other to meet the different water needs of the whole family.

[0041] The heat exchange plate group 12 includes a plurality of heat exchange plates 3 installed side by side, and the heat exchange plates 3 are provided with a plurality of heat exchange tube installation holes 31;

[0042] The heat exchange plate 3 is folded outward at the heat exchange tube installation hole 31 to form a first surrounding edge 32, and the outer edge of the first surrounding edge 32 abuts against the adjacent heat exchange plate 3, and the heat exchange tube installation holes 31 opposite to each other in the plurality of heat exchange plates 3 are spliced ​​together to form a heat exchange tube.

[0043] It is worth noting that a plurality of heat exchanger fins 3 are stacked and spliced ​​to form a heat exchanger fin group 12 with a plurality of channels inside, so that the flue gas can pass through the gap between two adjacent heat exchanger fins 3. A plurality of heat exchanger tube mounting holes 31 are provided in the heat exchanger fins 3, and a first surrounding edge 32 is provided on the heat exchanger tube mounting hole 31. The first surrounding edge 32 can separate two adjacent heat exchanger fins 3, so that the flue gas can be located between the two adjacent heat exchanger fins 3 for heat exchange.

[0044] Moreover, the first surrounding edge 32 can enable the heat exchange fin 3 to better adapt to pressure changes and better withstand external loads, thereby extending the service life of the heat exchange module 1.

[0045] A spring 33 is provided in the heat exchange tube, and the length direction of the spring 33 is consistent with the water flow direction.

[0046] The spring 33 can increase the disturbance of the water flow, so that the water flow forms turbulence in the pipe, thereby increasing the contact area between the water and the pipe wall. Turbulence can accelerate the heat dissipation of the water flow, because the collisions between water molecules in the turbulence are more frequent, thereby increasing the transfer of heat.

[0047] The spring 33 can also play a certain shock-absorbing role, reducing the impact of water flow on the pipeline, thereby extending the service life of the pipeline.

[0048] A slow flow sheet 34 is further provided in the heat exchange tube, the outer edge of the slow flow sheet 34 abuts against the inner wall of the spring 33, the length direction of the slow flow sheet 34 is consistent with the water flow direction, and the slow flow sheet 34 is spiral.

[0049] The slow flow sheet 34 can play a certain role in guiding the flow. When the water flows through the slow flow sheet 34, the water flow will be guided by the slow flow sheet 34 and evenly distributed on the inner wall of the heat exchange tube to form a rotating water flow, which not only avoids the situation of water flow concentration or insufficient water flow, but also can further improve the heat exchange efficiency of the heat exchange tube and prevent the situation of local high-temperature vaporization during high-temperature heat exchange. This rotating water flow can reduce the impact force of the water flow on the tube wall, thereby reducing the scouring and wear of the water flow, and can effectively improve the service life and stability of the heat exchange tube.

[0050] The slow flow sheet 34 can also play a certain role in reducing noise, thereby reducing the noise generated by the water flow.

[0051] A plurality of recessed portions 37 are provided at the bottom of the heat exchange plate 3 , and the recessed portion 37 is located between two adjacent heat exchange tube mounting holes 31 .

[0052] Since the combustion chamber in the water heater is located at the bottom of the heat exchanger, the flue gas can flow from the bottom of the heat exchanger to the vicinity of the heat exchange tube installation hole 31 to exchange heat with the water flow. Therefore, a plurality of recessed portions 37 are provided at the bottom of the heat exchange plate 3 to increase the flow range of the flue gas and further improve the heat exchange efficiency.

[0053] The heat exchange plate 3 is further provided with a plurality of heat exchange holes 35, and at least one heat exchange hole 35 is provided between two adjacent heat exchange tube mounting holes 31;

[0054] The heat exchange fins 3 are folded outward at the heat exchange holes 35 to form a second surrounding edge 36 , and an outer edge of the second surrounding edge 36 abuts against the adjacent heat exchange fins 3 .

[0055] The second surrounding edge 36 allows the flue gas to circulate in a circular pattern along the second surrounding plate when blowing over the surface of the heat exchange plate 3, thereby slowing down the rate of heat loss, extending the heat exchange time between the flue gas and the heat exchange plate 3, and thus improving the heat exchange efficiency of the heat exchange plate 3.

[0056] Among them, the present solution also stipulates that at least one heat exchange hole 35 is provided between two adjacent heat exchange tube installation holes 31, so as to further prolong the heat exchange time between the flue gas and the heat exchange plate and improve the heat exchange efficiency.

[0057] The heat exchange plate 3 is provided with a plurality of square through holes 38 , and one side of the square through hole 38 is folded outward to form a folded edge 39 .

[0058] The provision of the square through holes 38 and the folded edges 39 can further slow down the speed of heat loss, thereby improving the heat exchange efficiency of the heat exchange module.

[0059] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
