The gas water heater adopts gas as a main energy material, and high-temperature heat generated by gas combustion is transferred to cold water flowing through a heat exchanger so as to achieve the purpose of preparing hot water.
The gas water heater generally includes a housing, and a burner, a heat exchanger, a fan housing, and the like disposed in the housing.
Wherein, the gas is carried to combustor department, ignites the gas through ignition to make the combustor burn to the gas of carrying, and then produce the heat.
A heat exchange tube is arranged in the heat exchanger, one end of the heat exchange tube is communicated with a water supply pipeline, and the other end of the heat exchange tube is communicated with a shower head or a water faucet and the like.
The heat generated by the combustion of the gas by the burner is used for heating the heat exchange pipe, so that the water temperature in the heat exchange pipe is increased to form hot water.
When the gas water heater works, cold water provided by the water supply pipeline flows into the heat exchange pipe, is heated into hot water by the heating source generated by the burner, and then flows out from the shower head or the water faucet through the hot water valve for users to use.
Meanwhile, when the gas water heater works, the fan is electrified and runs simultaneously, and smoke generated by the combustor is discharged outdoors under the action of the fan.
In the first embodiment, as shown in fig. 1, the invention provides a gas water heater. The gas water heater comprises a shell 100, a burner 200, a burner 300, a control device 500, a water inlet pipe 101, a water outlet pipe 102 and the like.
The control device 500 includes a processor, a memory, and a control program stored in the memory and executable by the processor for the gas water heater.
The burner 200 can burn gas to heat water flowing in the burner 300, the water inlet pipe 101 and the water outlet pipe 102 are respectively connected with the heat exchanger 200 to form a heating water flow path, the electric heating module 400 is connected in series in the hot water flow path, and the electric heating module 400 performs auxiliary electric heating on the water flowing through by using the principle of electric heating.
The inlet pipe 101 is connected to a water supply pipe in the user's home to introduce cold water, and the outlet pipe 102 is connected to a water terminal (hot water tap) in the user's home to output hot water. The specific structural configuration of the gas water heater is not limited or described herein.
In order to realize electric auxiliary heating, the gas water heater further comprises an electric heating module 400, wherein the electric heating module 400 comprises a heating container and a thick film, an electric heating flow channel is formed in the heating container, and the thick film is wrapped outside the heating container; the water inlet pipe and the water outlet pipe are respectively connected with the heat exchanger to form a heating water flow path, and the heating container is connected in series in the heating water flow path; the thick film is used for firstly electrifying and heating water flowing through the heating container after the gas water heater is turned off and started again.
Specifically, during assembly, the heating containers in the electric heating module 400 may be connected in series in the heated water flow path formed by the water inlet tube, the heat exchanger, and the water outlet tube, for example: an electric heating module 400 is connected between the outlet pipe and the heat exchanger.
In actual use, when the user uses hot water, and when the user turns off the water and starts the water again, the user is easily scalded by outputting high-temperature water due to the limitation of the minimum heating power of the burner 200. For this purpose, the electric heating module 400 may be disposed between the water outlet pipe 102 and the burner 300, and when the gas water heater is turned on again after water is turned off, the gas water heater performs the following steps: the electric heating module 400 is started first, and water flowing through is heated by the electric heating module 400; after the hot water stored in the burner 300 flows out, the burner 200 is restarted and the electric heating module 400 is turned off.
Specifically, since the temperature of the stored water in the burner 300 is high when the water is used again, it is limited by the limitation of the minimum heating power of the burner 200, and if the water in the burner 300 is directly heated, the temperature of the outlet water is too high. For this reason, when the water supply is started again, the water flowing out of the burner 300 is heated by the electric heating module 400 to reduce the fluctuation of the outlet water temperature of the outlet pipe 102.
After turning off the water and turning on the water again for a certain time, the hot water stored in the burner 300 is outputted to allow the cold water to be re-flowed into the burner 300. At this time, the burner 200 may be activated to heat the burner 300 for normal hot water supply. Correspondingly, the electric heating module 400 may be powered off and stopped.
In the process of shutting off water and restarting water supply of the gas water heater, the fluctuation of the water temperature of the water outlet pipe 102 caused by the fact that water is shut off and the water is started again can be effectively reduced by executing the steps, and therefore the use experience of a user is improved.
In addition, adopt the thick film to heat the water that flows in the heating container as the heating source, can play the effect of even heating, the thick film parcel is in the outside of heating container, and heating container adopts heat conduction material (like aluminium, copper), and the heat that the thick film produced conducts to the water that flows inside through the heating container to realize the electricity and assist the heating.

The first water pipe 114 and the second water pipe 115 are spaced apart to allow sufficient distance between the inlet and outlet water to allow the first thick film 13 to effectively heat the water in the heating container. Meanwhile, the first thick film 13 may be disposed on the heating container by making full use of the interval between the first water pipe 114 and the second water pipe 115 to increase the heating power of the first thick film 13.
The heating container 11 is provided with a first connection port 111 and a second connection port 112, the first connection port 111 is provided with a first water pipe 114, and the second connection port 112 is provided with a second water pipe 115.

In a preferred embodiment, an electric heating tube 12 is further disposed in the heating container. Specifically, the water introduced into the gas water heater flows into the heating container 11 through the first water pipe 114, and heats the water introduced into the heating container 11 together with the first thick film 13 by the electric heating pipe 12.
In one embodiment, the heating container 11 includes a heating cylinder 116 and end caps 113 at both ends. The end cap 113 is sealingly connected to the heating cartridge 116 at a corresponding port location. The first connection port 111, the second connection port 112, and the mounting port are disposed on a side wall of the heating cartridge 116; the electric-heating tube 12 is disposed on one of the end caps 113.

Specifically, in the actual use process, the water inlet 221 is connected to the second connecting pipe 1021, and the water outlet 231 is connected to the water outlet pipe. A spiral plate 25 is located in the outer sleeve 22 and distributed around the inner insert 23, the spiral plate 25 being capable of directing the water flow in the outer sleeve 22 so that the water flow spirals between the outer sleeve 22 and the inner insert 23. Therefore, the flowing path of the water flow can be effectively prolonged, so that the water flow can be uniformly heated, and the requirement of instant heating type heating water is further met.
Wherein the helical plate 25 is arranged on the inner cannula 23.
Specifically, the spiral plate 25 is integrally formed in a spiral structure and is sleeved outside the inner insertion tube 23, so that the spiral plate 25 is fixed. The helical plate 25 may be welded to the inner cannula 23 or the helical plate 25 may be bonded to the inner cannula 23. The specific fixing connection between the spiral plate 25 and the inner cannula 23 is not limited and will not be described in detail herein.
In addition, for ease of installation and positioning, the outer edge of the spiral plate 25 is attached to the inner pipe wall of the outer sleeve 22.
In particular, after the inner cannula 23 is inserted into the outer cannula 22, the inner cannula 23 suspended in the outer cannula 22 can be better supported and positioned due to the edge of the spiral plate 25 abutting against the inner wall of the outer cannula 22. And, because the edge of the spiral plate 25 is abutted against the inner wall of the outer sleeve 22, the water flowing from the water inlet 221 is guided and conveyed by the spiral plate 25, so as to ensure the heating uniformity of the water flow.
In some embodiments, the water inlet 221 and the water outlet 231 may be disposed at the same end of the outer sleeve 22 and the inner tube 23, such that the inflowing water flows along the length of the outer sleeve 22 and then flows along the length of the inner tube 23 in the opposite direction. In this way, it is more beneficial for the water to be heated uniformly, so that the water outlet 231 outputs water with uniform temperature.
Specifically, when the electric heating module 400 is turned on again, a certain amount of hot water is stored in both the outer sleeve 22 and the inner insertion tube 23, so that after cold water enters the outer sleeve 22 again, the water flowing out of the inner insertion tube 23 can absorb heat and cool, thereby avoiding or reducing the problem that the temperature of the water outlet 231 is too high due to the fact that the hot water stored in both the outer sleeve 22 and the inner insertion tube 23 is heated again, and being more beneficial to improving the user experience.
In another embodiment, the electric heating module 400 further comprises a water treatment part 24, the water treatment part 24 is used for performing bacteriostatic and scale-inhibiting treatment on water flowing through, and the water treatment part 24 is arranged between the inner cannula 23 and the outer cannula 22;
when a user opens the water using terminal to use hot water, water in the water supply pipe enters the outer sleeve 22 through the water inlet 221, and the water entering the outer sleeve 22 is treated by the water treatment part 24 to perform bacteriostasis and scale inhibition treatment on the water, so that the effect of softening the water is achieved. The softened water continues to flow and is heated by the heat generated by the second thick film 21, and the heated water flows into the inner tube 23 via the auxiliary inlet 32 and is output from the inner tube 23.
On one hand, an installation space is formed between the outer sleeve 22 and the inner inserting tube 23 to place a water treatment part 24, so that water flow enters the outer sleeve 22 and then passes through the water treatment part 24 to be subjected to water quality treatment; on the other hand, a circuitous pipeline is formed between the outer sleeve 22 and the inner insertion tube 23, so as to prevent the water entering the outer sleeve 22 from flowing out quickly along with the water flow, so as to ensure that the water entering the outer sleeve 22 can be in sufficient contact with the water treatment part 24, and further meet the requirement of water treatment.
In some embodiments, to ensure that the inflowing water can be treated by the water treatment component 24, the water treatment component 24 may be disposed on one side of the water inlet 221 and cover the water inlet 221. Thus, the water flowing in from the water inlet 221 is treated by the water treatment component 24, flows into the inner insert tube 23 from the auxiliary inlet 32 and is output from the water outlet 231, so as to ensure that the flowing water is treated by the water treatment component 24.
In one embodiment, the water treatment component 24 is embodied in a variety of forms, such as: in the conventional antibacterial scale inhibitor provided at the water inlet end, preferably, the water treatment member 24 includes a plurality of granular materials 241, and the granular materials 241 are located at one side of the end of the spiral plate 25.
Specifically, a granular material made of a material having an antibacterial and scale-inhibiting function (e.g., silicon-phosphorus crystal) is filled between the outer sleeve 22 and the inner sleeve 23. After water flows in through the water inlet 221, the water can be in full contact with the granular materials 241, and then the contact area between the granular materials 241 and water flow is increased, so that the water flow is better subjected to bacteriostasis and scale inhibition treatment.
In order to prevent the granular material 241 from leaking out along with the water flow, the water treatment unit 24 further includes a shielding net 242, and the shielding net 242 is located between the spiral plate 25 and the granular material 241. Specifically, in use, after entering the outer sleeve 22, water will pass through the granular material 241 and pass through the shielding mesh 242 to flow along the direction of the spiral plate 25. Under the action of the shielding net 242, the granular material 241 is limited at one end of the outer sleeve 22, so that the granular material 241 is prevented from flowing along with the water flow. The size of the mesh formed by the shielding net 242 should be smaller than the size of the granular material 241.
Preferably, for heat preservation, a heat preservation shell 26 may be disposed outside the second thick film 21, on one hand, the heat preservation shell 26 can preserve heat generated by the thick film, and on the other hand, the heat preservation shell 26 can also protect the second thick film 21 from outside, so as to improve reliability and safety in use.
In some embodiments, to facilitate temperature sensing, a temperature sensor 27 may be provided at the end of the outer sleeve 22 remote from the water inlet 221, the temperature sensor 27 being located adjacent the auxiliary inlet 32 of the inner tube 23 to sense the temperature of the water flowing into the inner tube 23 to control the heating power of the second thick film 21. After the water flow reversely flows into the inner insert tube 23, the water flowing through the inner insert tube 23 can still be adjusted by the water temperature in the outer sleeve tube during the outflow process, and further the heating power of the second thick film 21 is adjusted according to the temperature of the water flow flowing into the inner insert tube 23, so as to accurately control the outlet water temperature of the water outlet 231.
In other embodiments, to facilitate removal and replacement of the water treatment component 24, the outer sleeve 22 is provided with a removable flange 28 at one end.
Specifically, during assembly, the flange 28 is mounted on a corresponding opening in the outer sleeve 22, and the inner sleeve 23 is sealed through the flange 28 and extends into the outer sleeve 22, thereby assembling the water treatment component 24 between the outer sleeve 22 and the inner sleeve 23. When the water treatment member 24 is to be replaced, the flange 28 is removed from the outer sleeve 22, and the water treatment member 24 can be replaced with a new one.
Preferably, for ease of assembly, the flange 28 may be secured directly to the inner insert 23, for example: the flange 28 is sealingly welded to the inner insert 23, and after the flange 28 is secured to the outer sleeve 22, the inner insert 23 can be installed to simplify assembly.
In order to effectively reduce the noise generated during the operation of the gas water heater, the fourth embodiment is based on the gas water heater in the first embodiment. As shown in fig. 1 and 8, the control method of the gas water heater includes:
step S101, calculating the heat Q required by the current heated inlet water flowt。
Specifically, after the gas water heater is started, when water flow enters the water flow to be heated, the corresponding heating source is judged and selected by calculating the heat required by the water flow heating.
Step S102, judging QtWhether the heat quantity Q is larger than the heat quantity Q generated by the electric heating module in the gas water heater0。
And S103, if so, starting a burner in the gas water heater to heat the water inflow.
Specifically, when the heating water flows to the set temperature and requires a large amount of heat, the burner 200 is started, and the burner 200 generates a large amount of heat to meet the requirement of the water flow on the heat.
And step S104, if not, starting the electric heating module to heat the inflow water flow.
Specifically, when the heating water flows to the set temperature and requires less heat, the electric heating module 400 is started, and the heat generated by the electric heating module 400 meets the requirement of the water flow on the heat. In this case, the burner 200 and the blower fan in the gas water heater are turned off while the electric heating module 400 is activated. At this time, the burner 200 and the fan do not need to be started, so that the noise generated by the burner and the fan is reduced, and the purpose of reducing the noise is achieved.
Wherein, for the calculation of the heat quantity required by the water inflow, according to the formula: qt=cρVt×(T0-Tt) Calculating QtWherein the water inlet flow is VtTemperature T of inlet watertAnd setting the temperature T0。
Specifically, the water inlet pipe 101 is provided with a temperature sensor and a flow sensor as required, and then the water inlet flow can be detected as VtAnd inlet water temperature Tt. While setting the temperature T0The Q of the heat quantity required by the inflow water flow can be calculated and obtained according to the formula and preset by a usert。
In the preferred embodiment, the gas water heater is further provided with a noise detector 600, and the noise detector 600 can send a signal of the noise detection to the control device 500. When the gas water heater is operated, the control device 500 controls the gas water heater according to a control program stored in the memory and executable by the processor.
As shown in fig. 1 and 9, the specific control method includes:
s201, noise generated in the operation process of the gas water heater is obtained.
Specifically, after the gas water heater is powered on and started, the noise detector 600 may detect noise generated during the operation of the gas water heater in real time, and the noise detector 600 sends the detected noise value to the control device 500.
S202, judging whether the acquired noise value is in a set noise range.
Specifically, after receiving the noise value signal sent by the noise detector 600, the control device 500 compares the noise value signal with the noise range information stored in the memory to determine whether the operating noise of the gas water heater exceeds the stored noise range.
S203, if the noise is within the set noise range, keeping the heating quantity of the burner and the electric heating module in the gas water heater unchanged.
Specifically, when the processor in the control device 500 analyzes and judges that the operating noise of the gas water heater is within the stored noise range, it indicates that the operating parameter of the gas water heater is appropriate, and then the processor continues to maintain the operating parameter.
And S204, if the set noise range is exceeded, adjusting the heating quantity of a burner and an electric heating module in the gas water heater until the acquired noise value is in the set noise range.
Specifically, when the processor in the control device 500 analyzes and judges that the operating noise of the gas water heater is within the stored noise range, it indicates that the operating parameters of the gas water heater are not appropriate, and the processor controls the burner 200 and the electric heating module 400 to adjust the operating parameters. And, in the process of adjusting the operating parameters of the burner 200 and the electric heating module 400, the noise is monitored in real time by cooperating with the noise detector 600 until the acquired noise value is within the set noise range.
In some embodiments, for a particular manner of adjustment of the operating parameters of the burner 200 and of the electric heating module 400, the following manner of adjustment may be carried out according to the magnitude of the noise values obtained.
And if the acquired noise value is higher than the maximum value of the set noise range, increasing the heating quantity of the electric heating module and reducing the heating quantity of the burner.
Specifically, when the acquired noise value is higher than the maximum value of the set noise range, it is necessary to perform noise reduction processing if the operation noise of the gas water heater is large. The noise reduction is performed by reducing the operating power of the noise generating components, and for this reason, the heating amount of the combustor 200 needs to be reduced; meanwhile, in order to meet the user's demand for using hot water, the heating amount of the electric heating module 400 needs to be increased simultaneously.
At this time, since the power of the burner 200 is reduced, the noise generated from the burner 200 is effectively reduced, and the noise reduction process is further implemented.
Wherein, as the power of the burner 200 is reduced, the power of the fan used in cooperation with the burner 200 can also be reduced accordingly. Therefore, under the condition that the acquired noise value is higher than the maximum value of the set noise range, the rotating speed of the fan in the gas water heater can be reduced simultaneously. After the rotating speed of the fan is reduced, the wind noise generated by the fan can be further reduced, and the reduction of the noise is facilitated.
On the other hand, in the control process, if the acquired noise value is lower than the minimum value of the set noise range, the heating amount of the burner is increased, and the heating amount of the electric heating module is decreased.
Specifically, in the case that the acquired noise value is lower than the minimum value of the set noise range, it is indicated that the noise level of the gas water heater meets the design requirement, and at this time, the heating efficiency needs to be improved, and obviously, the heating efficiency of the burner 200 is higher than that of the electric heating module 400.
Therefore, the heating power of the burner 200 is gradually increased and the heating power of the electric heating module 400 is simultaneously decreased. With the increase of the heating power of the burner 200, the noise generated by the gas water heater gradually increases, and in the process of increasing the heating power of the burner 200, the obtained noise value is within the noise range.
And the heating power of the burner 200 is increased and the heating power of the electric heating module is reduced, so that the running power consumption of the gas water heater can be more effectively reduced.
In addition, as the heating power of the burner 200 increases, the rotation speed of the fan in the gas water heater is correspondingly increased to ensure that the gas in the burner 200 can be sufficiently combusted.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
