Description

Background

Regarding the technology of developing a novel water heater by utilizing the venturi effect to solve the problem of storing more water in the traditional electric water heater, the inventor has already filed a plurality of patents. However, in the jet technology, pressure is converted into high-speed jet through a fine hole, so that energy loss is large, a plurality of swirling vortexes are caused by mixing in the throat, and energy is further lost, so that when large terminal resistance needs to be overcome, the water quantity is too small, the proportion of sucked hot water is too small, and a shower head, a valve and a hose with low resistance need to be adopted, so that a better effect is achieved. In actual use, because valve, gondola water faucet, the hose resistance diverse at terminal, the pressure of intaking also greatly differs for this technique uses and receives the influence. The best experience is achieved only by replacing the valve, the faucet and the shower head. This problem can become a limiting factor in the spread of the technology before it has not yet become a pandemic (of course, after the technology has become popular, the associated accessories will form new standards and will not be a problem). In order to solve the problem faced by the present technology, the patent adds a pump at the water outlet end or the suction end of the jet device, overcomes the terminal resistance by using the pump, and obtains good effect through tests. Meanwhile, due to the use of the pump, a jet device is not needed, the hot water is directly pumped by the pump to be mixed with the tap water, the function can be realized, the balance with the pressure of the tap water is only needed, and certain requirements are also met for the pump lift.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The invention is further illustrated by the following figures and examples.

Example one

In this embodiment, a single heater is installed in the energy storage tank 2 and includes the fluidic device 3, and there are many practical subdivision schemes under this broad scheme, which will be described separately below.

As shown in fig. 1, the tap water flow path is: the water flows through the water flow detection unit 6 after passing through the water inlet end 14, then passes through the jet device 3 and the water filling device consisting of the stepping motor 7 and the water filling valve 8 in two paths, the water flow passing through the jet device flows out of the water outlet end 15 after passing through the pump 5, and the part passing through the water filling device flows out of the spray pipe 16. Including two water level detection wares, a floater inductive switch 11 for the lowest water level of response, a water level detecting element 9 for can respond to water level continuous variation, the floater is movable, is died by the incrustation scale card easily, so in the actual product, can use induction mode such as electric capacity, resistance, floater inductive switch 11 here has two effects, and first is as the dual fail-safe of low water level protection, and another is as the calibration foundation of water level detecting element 9. For example, when the water level detection unit 9 uses a load cell as a detection element, a zero point may drift due to a slight deformation caused by a long-term force, and the calibration needs to be performed automatically from time to time. The suction end of fluidic device 3 passes through check valve 10 and drain pipe 17 intercommunication, the drain pipe is connected in energy storage tank 2's lowest, when the running water flows through fluidic device 3, high-speed efflux can produce certain vacuum at the suction end, in case fluidic device's structure is confirmed, the terminal resistance is in suitable scope, the size and the efflux speed of this vacuum are directly proportional with the flow, it draws out the hot water in energy storage tank 2 according to certain proportion according to the inflow, flow after the choke and subsequent pipeline and the cold water intensive mixing of fluidic device again. The heating unit adopts a common electric heating tube 4 (the cost and the practicability are mainly considered, and any other mature heating scheme such as an electromagnetic heater and the like can be adopted for realizing the function), the electric heating tube 4 is assembled at the bottom of the energy storage box 2, and if the electric heating tube is to be arranged at the middle part or the upper part, a water pump is additionally arranged to enable the water at the bottom to be uniformly heated. In the figure, elements of the industry known technology such as a temperature sensor, a temperature protection device, a circuit board and the like are uniformly omitted.

When the water flow detecting unit 6 senses that water flows, the pump 5 works to overcome the terminal resistance and increase the water amount. As shown in fig. 1, when no water flows through the water outlet end 15 and only the water filling device fills water into the energy storage tank, the water flow detection unit 6 also senses the water flow, so that the pump 5 operates, and the pump 5 does not need to operate at this time, so that the water flow detection unit 6 is placed at this position, which has a defect. This problem can be solved if the water flow detecting unit 6 is installed after the water filling means branch. The hot water outlet of the water heater with the structure is arranged at the bottommost part of the energy storage tank, so that hot water can be used up; the water level can be adjusted at will; the temperature of the inner container can be ensured to be quite constant when water is used, and a cold-hot water mixing layer is not required to be formed in the traditional water heater; the double-mode effect of instant heating and water storage can be realized by a single heater; because the bottom discharges hot water, the scale can be discharged in time, which is equivalent to cleaning in time and is more sanitary.

As shown in fig. 2 and 11, the scheme of the present figure is different from that of fig. 1 in that: the water is added into the inner container and the water is discharged through the suction end of the jet device; constant temperature control can be carried out; the water flow detection unit 6 is arranged at the water outlet end of the jet device; the water level sensing adopts two floating ball inductive switches 11. FIG. 11 is a schematic view showing the states of the multifunctional valve 13, 11-1 is a schematic view showing the stationary plate fitted in the valve seat, and 11-2 is a schematic view showing the movable plate. Fig. 11-3 is a schematic diagram of the multifunctional valve when the jet channel is fully opened when water is supplied to the outside, at this time, tap water enters the center hole of the fixed valve plate from the valve 13a, flows to the jet channel 13c through the movable valve plate water inlet communicating groove 13f, the suction channel 13e is communicated with the suction communicating groove 13g of the passive valve plate 13d, and the bypass channel 13b is completely closed at this time and no water flows through. As shown in fig. 11-4, in this state, when the water temperature needs to be reduced, the bypass channel is opened, the flow rate of cold water is increased, the water inlet communicating groove 13f of the movable valve plate simultaneously communicates with the jet channel 13c and the bypass channel 13b, and the suction channel 13e communicates with the suction communicating groove 13g of the passive valve plate 13 d. Fig. 11-5 are schematic diagrams of reducing water inflow, when the temperature needs to be increased, the flow of water inflow needs to be reduced properly, and the superposed section of the movable valve plate communicating groove 13g and the fixed valve plate jet flow channel 13c in the diagrams is reduced, so that the hot water proportion can be increased. Fig. 11-6 are schematic views showing the state of filling water into the inner container, in which the suction channel 13e is communicated with the suction communicating groove 13g of the passive valve plate 13d but the channel section is reduced to control the water flow. Fig. 11-7 are schematic views of the machine in a state in which it supplies neither water to the inner container nor water to the outside, when the water inlet communicating groove 13f of the movable valve sheet communicates with the bypass passage 13b, and the suction passage is closed.

This scheme is when using hot water, because the suction end produces the negative pressure, and energy storage box 2 supplies water outwards this moment, can't fill water in energy storage box 2 for hot water output volume diminishes, is suitable for the outage and washes and great volumetric water heater.

Fig. 3 differs from fig. 1 in that: the pump 5 is arranged at the suction end of the fluidic device 3, and a temperature adjusting device 12 is added. The pump 5 is assembled at the suction end of the fluidic device worse than at the water outlet end, which not only destroys the relatively constant proportion of cold and hot water of the fluidic device, but also has a bad influence on the service life of the pump due to the high-temperature water in the energy storage tank. The thermostat 12 is composed of a stepping motor and a thermostat valve, which is similar to the multi-function valve in fig. 2, but has less control over the suction side of the injection device 3, and is not described here.

In addition, some parts in different drawings can be installed in other drawings, for example, the temperature adjusting device 12 in fig. 3 can be installed in fig. 1, fig. 3 can also eliminate the water filling device and the temperature adjusting device 12, and the multifunctional valve in fig. 2 is adopted, in short, many characteristics in the patent drawings can be interchanged without conflict.

The general scheme of the water heater manufacturing process is only convenient to understand, all main parts are unfolded as far as possible and are not overlapped so as to be convenient to understand and view, the actual structure is compact as far as possible, and meanwhile, the details of known technologies in the industry such as a temperature sensor, a control circuit board and the like are also omitted in the drawing. The energy storage box of this patent can adopt PP blow molding, and its bottom design opening is used for the device to have to be connected to the part on the energy storage box 2, for example heating element, various pipe fittings connect and water level sensing device. The water level sensing of energy storage box can adopt various forms such as forced induction, tongue tube switch, hall switch, resistance sensing, capacitive sensing, radar response, infrared induction, and the more economic scheme is tongue tube response and hall response, and the essence of these two kinds of modes all is the magnetic induction, can adorn inductive switch at the top of energy storage box. In order to continuously sense the water level, pressure sensing may be used. In this embodiment, there are one to two pipes to be connected to the energy storage tank, only the water discharge pipe 17 is connected to the energy storage tank in fig. 2, the water feeding, discharging and discharging of the energy storage tank all pass through the interface, and the suction end of the jet device is connected to the water discharge pipe 17, so that the advantage is that a filter screen is arranged at the port of the jet device connected to the water discharge pipe, so that the large scale peeled off from the heater falls into the water discharge pipe 17, and the small scale is discharged through the jet device at any time. These pipe joints and mounting holes for the water level sensor can be integrated into the flange of the electric heating pipe 4. The jet device is simple in structure, can be formed by injection molding, and is convenient to be connected with other parts because the three ports are manufactured into a threaded structure. The outlet end 15 of the water heater can also be directly integrated into the fluidic device 3, since in the actual product, the 90-degree bend as shown in the figure may not be needed, but is straight, so that the mold can be made into a whole, even an elbow, just by using a slide on the mold. The water inlet end 14 of the water heater may be part of the water flow detection unit 6, and since the moving parts of the water flow sensing unit may be stuck by silt, the water flow sensing unit is generally assembled in the straight pipe of the water inlet joint, and is convenient to detach and clean.

Example two

The second embodiment is a scheme of assembling the heating unit outside the energy storage box 2, the liner of the scheme does not have any wearing parts, and a series of subdivision schemes are also included, and the patent only lists the most main implementation modes. As shown in fig. 4, the heating unit is composed of the second electric heating tube 20, a heat exchanger 21 and a heater shell 22, the heat exchanger 21 is an instant heating channel for heating running water, and a space formed by the heater shell 22 accommodates a heat transfer medium for heating the heat exchanger 21 on one hand and serves as a channel for circularly heating a heat storage medium in the energy storage tank on the other hand. Of course, the functions of the two channels formed by the heat exchanger and the heater shell can be interchanged, the heat exchanger is used for circulating heating, and the space of the heater shell is used for heating running water flowing through. The heating unit can also adopt a cast aluminum heater, only two groups of heat exchange tubes need to be wound in the cast aluminum heater, and any feasible heater comprising two mutually isolated heating channels can meet the function. Because the heating unit is arranged outside the energy storage tank 2, the water in the energy storage tank can be heated only by using pump circulation, the effect of circulating heating and pressurization is realized by using the pump 5 in the figure, and the waterway communicated with the pump 5 is switched by using the reversing mechanism 24. FIG. 12 is a schematic view showing the states of a direction change valve of the direction change mechanism, and FIG. 12-1 is a schematic view showing a fixed valve plate of the direction change valve fitted in a valve seat, wherein two

ports

24a and 24b are connected to a water pump; FIG. 12-2 is a schematic view of a reversing valve moving plate; FIG. 12-3 is a schematic view of the first position of the diverter valve in which the movable vane plate communicates both

ports

24c and 24d with the pump 5; fig. 12-4 are schematic views of the second position of the reversing valve, in which the moving vane plates communicate both

ports

24e and 24f with the pump 5. The principle of the multifunctional valve 13 is completely consistent with the first embodiment and will not be described in detail here. The reversing mechanism 24 and the multifunctional valve are both driven by a motor, and generally, the reversing mechanism and the multifunctional valve can be better controlled by using a stepping motor, if two stepping motors are adopted to respectively control the reversing mechanism and the multifunctional valve, the elements and the cost are increased, the space is also wasted, the failure rate is increased, and therefore, the reversing mechanism and the multifunctional valve can be controlled by using one motor. The method for controlling the two valves by using one motor comprises the following steps: the two valves are located in different angular sectors of the motor. When the water heater supplies hot water to the outside, the internal circulation does not work, the reversing valve rotates to enable the pump to be communicated with a tap water channel, and at the moment, a gear on the stepping motor is positioned at the adjusting position of the multifunctional valve and used for adjusting the temperature of the outlet water; when the water heater does not circularly heat the energy storage tank, does not supply hot water to the outside and does not add water into the energy storage tank, the stepping motor rotates to enable the multifunctional valve to be positioned at the position 11-7 in the figure 11, at the moment, the multifunctional valve closes the channel at the suction end of the jet device, and the reversing mechanism is positioned at the position for communicating the pump with the tap water channel; when water needs to be filled into the energy storage tank 2, the multifunctional valve rotates anticlockwise at the position of 11-7, so that a suction channel of the jet device is communicated, the temperature of the filled water is controlled by adjusting the size of the channel, the water filling temperature can reach the set temperature of the energy storage tank in one step, for example, the energy storage tank is set to be 60 ℃, and the size of a circulation section of a suction end can be adjusted to enable tap water to be equal to 60 ℃ after being heated by the heating unit; when the water heater needs to circularly heat water in the energy storage tank, the stepping motor continues to rotate clockwise at the position of the multifunctional valve 11-7, please note that 11-7 is a dead point position of the multifunctional valve, when the water heater continues to rotate anticlockwise, the gear of the multifunctional valve 11 is disengaged from the gear of the stepping motor (the function can be realized by making the gear on the motor into a sector), at the moment, the stepping motor enters a region meshed with the gear of the reversing mechanism, and the reversing mechanism is adjusted to enable the water pump to be communicated with the circular heating channel. Of course, if the adjustment is not good with one motor, the actual product can also use two motors to control the two components separately.

In the scheme that the heating unit is arranged outside the energy storage box, the heating unit is particularly required to be filled with water when the energy storage box is filled with water, and meanwhile, the structure of the heating unit can ensure that the water is filled and air is not trapped in use, so that the parts of the two ends of the circulating pipeline, which extend to the liner, cannot be on the same plane, enough fall is required to be ensured, and meanwhile, the structure and the pipeline are connected, so that gas generated in heating can be immediately discharged. If the reversing valve can not ensure that the circulating channel is opened when water is filled for the first time, a bypass channel is added, otherwise, water cannot enter the heating unit when the water is filled.

As shown in figure 4, a by-pass pipe is connected in parallel with the reversing mechanism 24 on the tap water channel, a one-way valve is arranged on the by-pass pipe, the direction of the one-way valve is directed to the water outlet end of the water heater, the by-pass pipe has the function that when the reversing valve is switched to the circulating channel, when water is used from the outside, water can pass through the by-pass pipe, so that the water flow switch can sense a water flow signal to start other programs, for example, when hot water is sensed to be used from the outside, the circulating heating is stopped, the pump is immediately communicated with the tap water channel to be pressurized, and the stepping motor enters the regulating region of the multifunctional valve to carry out thermostatic control.

Fig. 5 differs from fig. 4 in that a circulation pump 23 is added and a reversing mechanism 24 is eliminated. When it is desired to heat the heat storage medium in the energy storage tank 2, the circulation pump 23 is activated. When the water flow switch is started, the water heater supplies hot water to the outside or fills water into the inner container, and the circulating pump 23 does not work. The working principle of other parts is described above and will not be described in detail.

EXAMPLE III

Fig. 6 is a schematic diagram of a third embodiment, and as shown in the figure, two sets of heating units are adopted, and an external heating unit two 19 is disposed at a water inlet end of the fluidic device 3, and may also be disposed at a water outlet end, but is disposed at the water inlet end, so that the working temperature is lower, which is beneficial to protecting the heaters and reducing scale formation. The electric heating pipe 4 is assembled in the energy storage box 2 and heats the water stored in the energy storage box. In this way, the pump in the second embodiment is not needed to circulate the water in the energy storage tank, the second heating unit 19 can be prevented from easily forming scale due to too high heating temperature, certainly, the electric heating tube 4 also has scale, but the space is large, so the influence is not great, the electric heating tube can also adopt the coating to prevent the scale from adhering, and the scale cannot be accumulated in the liner due to the adoption of the scheme of discharging water. The shortcoming of this scheme lies in can't wash energy storage tank bottom through intaking and pump circulating water, can not be fine erode the incrustation scale that stores up to the minimum. The working mode of the scheme is as follows: when the water heater is started, whether water flow passes through is detected, and if the water flow does not pass through, the second heating unit 19 does not work; if water flows through the multifunctional valve, the electric heating pipe 4 does not work, the heating unit II works, and the multifunctional valve 13 adjusts the valve core to rotate to realize the constant temperature effect. If the outlet water temperature of the water in the energy storage tank is not sucked and still exceeds a set value, the constant temperature is realized by adjusting the power of the second heating unit. Except that two heating units are adopted, the working principle of other parts is basically the same as that of the first embodiment, and the description is not repeated.

Example four

As shown in fig. 7, the embodiment is made into a modular design based on the second embodiment, and the waste of social resources can be greatly reduced by making into the modular design. This patent water heater's energy storage tank 2 is owing to need not the pressure-bearing, so can adopt plastics to make, selects suitable plastic material and forming process, can accomplish extremely long life-span, for example domestic water pipe PPR material is PP and PE, and pressure is suitable to exceed 50 years at 80 degrees temperature under life. When the water heater inner container is used as a water heater inner container, the water heater inner container does not bear pressure and is free from illumination, and the service life is longer under the condition. In the second embodiment, the energy storage box has no wearing parts, only has a plurality of pipe fittings, and the inner container and the heat preservation foam can be independently made into the heat storage module 31; the heat generating module 30 is formed by separately assembling vulnerable parts such as a heater, a circuit board, a motor, a sensor, a valve and the like, the two parts only need to be connected through a plurality of water interfaces, the pressure of water passing through the joints can be small to be ignored, and the sealing is easy. The heating module and the heat storage module can be assembled together to form a whole, so that the solar heat collector is attractive and compact in appearance. The split type heating device can also be made into a split type by pipe connection, which can be very practical in certain occasions, such as the large water storage part is hidden on a ceiling, and the heating unit is arranged in a place convenient to operate. Meanwhile, the heating module can be independently used as an instant water heater. The heat storage module occupies most of the volume of the water heater, and can not be replaced for decades, only the heating module needs to be replaced when the water heater is damaged, the manufacturing, replacing and after-sale costs are greatly saved, and social resources are greatly saved. Since the scheme is basically the same as the second scheme, the scheme is divided into two parts, and therefore, the description is not repeated.

EXAMPLE five

Fig. 8, 9 and 10 are schematic diagrams of a fifth embodiment, which is different from the previous embodiments in that the jet device 3 is eliminated, and the hot water in the energy storage tank 2 is directly pumped by the pump 5 to be mixed with the tap water which is preheated or not preheated. The problem with this solution is that the pump cannot discharge or be flushed back when the tap water pressure is greater than the pump pressure; when the pressure of the pump is higher than that of the tap water, the tap water is pressurized back. The jet device is a completely different principle, hot water in the energy storage tank is pumped out by using the energy of tap water, cold water and hot water are naturally mixed according to a certain proportion in the mode, the larger the flow of the cold water is, the larger the flow of the hot water is, and the pump is only used for overcoming terminal water resistance in the scheme with the jet device, because the jet device is sensitive to the resistance of the outlet water. Meanwhile, if the hot water is pumped out by the water pump directly, and the mixing is realized by the external water mixing valve, the problem is also faced, because the pressure in the energy storage tank is absent, when the hot water is used outside, no hot water flows out, the water flow switch cannot sense a water flow signal even if the water flow switch is arranged at the hot water end, and the water pump cannot be started to work by sending the signal. Therefore, in the fifth embodiment, an automatic water mixing valve 25 is required to be arranged for adjusting the pressure of the tap water and the pressure of the pump so that the tap water and the pump can supply water according to a certain proportion, and the water supply pressure of the water heater depends on the smaller pressure. Another disadvantage of this approach is the need to withstand high temperatures because the hot water, which is not mixed with cold water, passes through the pump. At the same time, this has the advantage that the pump does not have to withstand high tap water pressures, after all in places where the water pressure is high, up to 7 kg.

As shown in fig. 8, the water heater has a special water filling device, which is composed of a stepping motor 7 and a water filling valve 8, one end of the pump 5 is communicated with the water discharging pipe 17, and the other end is connected with the one-way valve 10 and then connected with the hot water input port of the automatic water mixing valve 25, and the branch is a hot water output branch and is powered by the pump. The purpose of the check valve is to prevent tap water from flowing into the inner container from the branch of the pump when the pump is not started or the external pressure cannot be overcome by the force of the pump, certainly, the function of backflow prevention is achieved when the diaphragm pump is adopted, the service life of the diaphragm pump can only be one thousand hours at present, even less than one thousand hours in most cases, the diaphragm pump is not suitable for a water heater, and the service life of the centrifugal pump reaches more than ten thousand hours, so that the requirement is completely met. Tap water is connected with the cold water input end of the automatic water mixing valve 25, and cold and hot water flows out through the output end of the automatic water mixing valve. The temperature sensor is arranged at the water outlet end, not shown in the figure, the temperature data collected by the sensor is compared with the set value, and the automatic water mixing valve automatically adjusts the proportion of cold water and hot water according to the data.

Fig. 9 shows another embodiment of the fifth embodiment, which is basically the same as the second embodiment, and the heating unit is externally arranged, and the pump 5 is used to realize the circulation heating and the hot water pumping in the energy storage tank at the same time, so that the reversing mechanism 24 is adopted, and the operation mode is completely the same as the second embodiment. Since the pressure of the pump and the tap water may vary greatly (which is completely different from the pressure of the cold and hot water supplied from the same source in a conventional water heater), an automatic mixing valve 25 is used as in fig. 8. Since this embodiment is a combination of the second embodiment and fig. 8, it is not described much.

Fig. 10 is a plan of combining heat exchange and hot water suction, and the idea of the plan is to provide hot water in a heat exchange mode as much as possible, because the heat exchange mode can realize no scale deposit, firstly, the high-speed water flow in the heat exchange pipe can prevent the scale deposit from being generated in the pipe, and in addition, the water in the energy storage tank can not be used, and only a small amount of evaporated water needs to be supplemented, so that no new impurities are brought in, and the scale deposit can be ignored only by the amount obtained by burning the barrel. However, the heat exchange also has the defect that hot water cannot be used up, even if the heat exchange enhanced heating dual-mode technology is adopted, when the temperature of inlet water is very low in winter, hot water with enough temperature cannot be provided when the temperature of the water in the inner container is only about 26 ℃, when the temperature of the water is reduced to be unusable and a user needs to use the hot water, the second reversing valve 26 is switched to a channel connected with the energy storage box, the pump 5 is started, and at the moment, the water in the inner container flows out after being secondarily heated by the heating unit to reach the bathing temperature. The heating unit in the figure is vertically installed, so that water in the energy storage tank cannot be used up, and if the heating unit is horizontally installed at the bottom of the inner container or is arranged outside the inner container, the water in the inner container can be used up as much as possible. Assuming that the capacity of the inner container is 30 liters and the water yield is 5 liters/minute, the service time can be prolonged by 6 minutes in the case. The heating unit of this scheme has adopted a new structure, this is the structure of special design in order to satisfy the bimodulus effect of instant heating and heating energy storage box water storage, and of course, this kind of structure is not very feasible in the scheme that does not adopt the heat transfer, unless quality of water is very good, this is because when the continuous new water that has of energy storage box supplyes, the incrustation scale can be tied up on the heater, if the space of heater is too little, will block up soon. In the figure, the dual-channel heater is assembled inside the energy storage box (in the previous scheme, the dual-channel heater is placed outside), and the opening and closing of the opening on the heater shell 22 are controlled by the thermal bulb assembly 28, and the opening on the heater shell is used for heat convection with the energy storage box 2. When the heat exchanger 21 can absorb the heat energy generated by the heater (at this time, the temperature in the heater shell is not too high and is less than the temperature of the top opening of the thermal bulb component), the thermal bulb component closes the pore channel under the spring force. When the heat that the heater produced can't be used up by the heat exchanger, the temperature in heater shell 22 can be higher and higher, is higher than the top temperature of thermal bulb subassembly at last, and the size of opening the pore is confirmed according to the temperature in heater shell 22 to the thermal bulb subassembly, and the higher the temperature, open more greatly, dispel the heat in the energy storage box more fast. When the temperature of the inlet water is higher, the instant heating effect can be realized, the water in the energy storage tank does not need to be heated, the water flow switch is started to heat the water, no water flow stops heating, and the tap water is heated to the use temperature after flowing through the heat exchanger 21; when the temperature of the inlet water is lower, the water in the energy storage tank needs to be preheated and insulated firstly, at the moment, when the temperature in the energy storage tank is lower than the preset temperature, no water flow passes through the heating unit and can be started to heat, cold water flows through the second heat exchanger 29 to absorb heat energy in the energy storage tank for preheating, and then flows out after being subjected to second-stage heating through the heat exchanger in the heating unit; when the temperature of the water in the energy storage tank is reduced to a temperature which cannot enable the outlet water to reach the proper temperature, the warm water in the energy storage tank is directly pumped out for secondary heating as mentioned above and then used. This solution is designed to solve the scaling and to provide as much hot water as possible in winter.

The pump 5 in fig. 10 is not only used to pump the stored water in the storage tank, but also used for pressurization and zero cold water circulation, and the second embodiment also has the function. Meanwhile, as shown in fig. 10, the scheme of comprehensive heat exchange can also be used in the first scheme and the second scheme, and the modular scheme of the fourth embodiment can also be used in the fifth embodiment, only simple adjustment is needed.

The above examples are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and all combinations and subcombinations of the various aspects of the invention are contemplated as falling within the scope of the invention.
