DETAILED DESCRIPTION

[0020] The utility model provides a hydraulic module. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0021] Figure 1 The direction indicated by the arrow is the direction of water flow.

[0022] See also Figure 1 and Figure 2 The utility model provides a hydraulic module, including a box body 100, and a water pump 1, a first calorimeter 2, a heat pump 3, a heater 4 and a water tank connected in sequence through pipelines, the water pump 1, the first calorimeter 2 and the heater 4 are all arranged inside the box body 100, and the heat pump 3 and the water tank are both arranged outside the box body 100; the water pump 1 is provided with a water inlet, and the water outlet of the water tank is connected to the water inlet of the water pump 1; the box body 100 is also provided with an expansion tank 14, and the expansion tank 14 is connected to the side wall of the pipe of the water inlet of the water pump 1 through a pipe.

[0023] The water pump 1 is used to provide power and suck water into the water system so that the water can circulate in the water system. After the water flows into the water pump 1 from the water inlet of the water pump 1, the water flowing through the water pump 1 enters the first calorimeter 2 to calculate the flow rate, and then enters the heat pump 3 through the pipeline for heat exchange. The water temperature after the heat exchange increases, and enters the heater 4 through the pipeline for heating. After the water reaches the set temperature, it flows into the water tank for standby. The additional expansion tank 14 can play the role of water storage, that is, as a water capacity regulator. When the water system heats up, the increased water in the pipeline due to thermal expansion is absorbed by the expansion tank 14 and stored in the expansion tank 14; when the water system cools down / cools down and leaks, the volume of water in the pipeline decreases, and the expansion tank 14 can be used to replenish water in the water system in time; on the other hand, it can also play a role in constant pressure. The expansion tank 14 is provided with an air bag or pre-filled with nitrogen. When the air pressure of the water system changes, the pressure in the water system can be balanced by the change of the water flow direction in the expansion tank 14. Moreover, the point where the expansion tank 14 is connected to the water system serves as a constant pressure point or constant pressure point of the water system, thereby ensuring that the water system is not emptied, overflowed, or over-pressurized. The expansion tank 14 in this embodiment is arranged at the water inlet of the water pump 1, and the constant pressure effect of the expansion tank 14 plays a certain protective role on the water pump 1. Through the pressure regulation function of the expansion tank 14, the frequent start or stop of the water pump 1 can be reduced, the service life of the water pump 1 can be extended, and the stability and operation safety of the water system can be improved.

[0024] In some embodiments, the box body 100 is further provided with an AHS water inlet 81, an AHS water outlet 82 and a second calorimeter 9, and an AHS 8 is further provided on the pipe between the AHS water inlet 81 and the AHS water outlet 82; the AHS water inlet 81 is provided on the side wall of the water inlet pipe of the water pump 1, the AHS water outlet 82 is connected to the water inlet of the second calorimeter 9, and the water outlet of the second calorimeter 9 is connected to the water inlet of the water tank. The water that does not flow through the water pump 1 enters the AHS 8 through the AHS water inlet 81, and then enters the second calorimeter 9 through the AHS water outlet 82 to calculate the flow rate, and then gathers in the water tank. If the water in the water tank is overheated, the water in the water tank can be cooled to make the water temperature in the water tank reach the set temperature.

[0025] In some embodiments, the water tank includes a domestic water tank 6 and a balancing water tank 7. A three-way valve 5 is provided on the pipe of the water outlet of the heater 4. The two water outlets of the three-way valve 5 are electrically connected to the water inlet of the domestic water tank 6 and the water inlet of the balancing water tank 7 respectively; the water outlet of the domestic water tank 6 is connected to the first water inlet 11 of the water pump 1, and the water outlet of the balancing water tank 7 is connected to the second water inlet 12 of the water pump 1. The domestic water tank 6 is mainly used to store and supply clean water required for daily life. It can serve as an intermediate water storage link to ensure that the user's water demand can be temporarily met even in the case of water supply interruption or insufficient pressure. The balancing water tank 7 is also called a buffer water tank, which is mainly used to stabilize the water pressure and water volume in the water system, especially when the load changes greatly, to alleviate the water volume change caused by the change of water temperature, avoid the sharp fluctuation of the water system pressure, and protect the entire water system. Therefore, in actual use, the three-way valve 5 can be set to use the water in the domestic water tank 6 or the water in the balancing water tank 7 according to the needs of customers by turning the valve core in the three-way valve 5, such as turning to use.

[0026] In some embodiments, a magnetic mud filter 15 is further provided on the pipeline downstream of the first water inlet 11 of the water pump 1 and the second water inlet 12 of the water pump 1. The magnetic mud filter 15 is provided at the water inlet of the water pump 1, so that when water flows into the magnetic mud filter 15, the magnetic particles are adsorbed on the magnetic chip, thereby achieving the purpose of filtering the water body.

[0027] In some embodiments, the magnetic mud filter 15 and the pipe with the AHS water inlet 81 are provided with a first temperature sensor 91; the second calorimeter 9 is provided with a second temperature sensor 92 on the side wall; the first calorimeter 2 is provided with a third temperature sensor 21 on the side wall; the pipe of the water inlet of the three-way valve 5 is provided with a fourth temperature sensor 22 (since the fourth temperature sensor 22 is blocked by the pipe joint, the position indicated in the figure is the pipe joint); the first temperature sensor 91, the second temperature sensor 92, the third temperature sensor 21 and the fourth temperature sensor 22 are electrically connected to the heat exchange control system respectively. Multiple temperature sensors installed at the water inlet and outlet feed back different pulse signals for different temperatures, the first calorimeter 2 and the second calorimeter 9 are used to collect signals respectively, and calculate the heat obtained by the heat exchange control system, output hot water through the heater 4, and the user inputs parameters such as temperature and water volume, so that the price can be automatically calculated.

[0028] In some embodiments, the housing 100 is further provided with an electric control box 10, and the electric control box 10 is provided with an electric controller 101. The electric control box 10 is provided with electrical components for controlling the water system. The electric control box 10 is provided with the electric controller 101 so as to be sealed therein, that is, the electric controller 101 is separated from the hydraulic module, so that water can be prevented from penetrating into the electric control box 10, thereby preventing leakage.

[0029] In some embodiments, the expansion tank 14, the heater 4 and the electric control box 10 are all located at the upper part of the box 100, and the expansion tank 14, the electric control box 10 and the heater 4 are arranged in sequence from left to back. The above arrangement makes the design of the interior of the box 100 more reasonable and compact, and can make full use of the space inside the box 100.

[0030] See also Figure 3 In some embodiments, a hanging plate 200 is provided on the back of the box 100, and the hanging plate 200 is used to hang with a hanging piece fixed on the wall. The assembled box 100 can be quickly positioned on the wall through the cooperation of the hanging plate 200 and the hanging piece.
