Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In a first embodiment, as shown in fig. 1 and fig. 2, the present invention provides a method for controlling a gas water heater, wherein the gas water heater includes a housing 100, a burner 200, a burner 300, an electric heating module 400, a control device 500, a water inlet pipe 101, a water outlet pipe 102, a fan 103, a water pump 104, and other components. 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.
When the user turns off the water and restarts the water supply while using the hot water, the user may be easily scalded by outputting the 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:
s101, the electric heating module 400 is started first, and water flowing through the electric heating module 400 is heated.
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.
S102, 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, 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, so that the cold water is 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.
Second embodiment, as shown in fig. 2 and 3, since the burner 200 is composed of a plurality of fire rows for heating, different numbers of fire rows generate different amounts of heat and different noises, so that the burner 200 has a multi-stage heating mode, and the different fire rows are controlled to burn gas in different levels of heating modes. In order to effectively reduce the noise generated during the operation of the gas water heater, the control method further comprises the following steps:
s201, after the gas water heater is started, along with the increase of load, whether the maximum heating power of the burner exceeds the maximum heating power of the burner in the N-section heating mode is judged.
Specifically, the gas water heater mainly depends on the burner 100 to burn gas to heat water during normal operation, and the burner 100 generates certain noise during the burning process, and the noise generated by the burner 100 is larger as the heating power is increased.
S202, if the burner does not reach the maximum heating power in the N-section heating mode, the heating power of the burner in the gas water heater is increased.
Specifically, in the N-stage heating mode, for the increase of the load, the heating amount is first satisfied by increasing the heating power of the burner in the N-stage heating mode.
S203, if the burner is increased to the maximum heating power of the N-section heating mode in the N-section heating mode, starting an electric heating module in the gas water heater for auxiliary heating.
Specifically, when the load continues to increase when the burner is at the maximum heating power in the N-stage heating mode, the requirement cannot be satisfied by only depending on the heating amount of the burner in the N-stage heating mode. And if the N +1 section heating mode is executed, the operation noise is increased, and at the moment, the electric heating module in the gas water heater is started for auxiliary heating. The electric heating module can meet the heating requirement exceeding a certain amount due to load increase in the N-section heating mode, so that the gas water heater is at a reduced noise level.
In another embodiment of the present application, if the load continues to increase during the operation of the gas water heater, the control method of the gas water heater of this embodiment further includes:
s204, in the N-section heating mode, when the electric heating module is at the maximum heating power and the load of the gas water heater is continuously increased, the gas water heater executes the N + 1-section heating mode.
Specifically, when the heating power of the burner and the heating power of the electric heating module cannot meet the load requirement in the N-section heating mode, the gas water heater executes the N + 1-section heating mode. After the gas water heater is switched to the N +1 section heating mode, the heating power of the burner is gradually increased, and the heating power of the electric heating module is gradually reduced until the electric heating module is closed. Wherein the maximum heating power of the burner in the N-section heating mode is not greater than the minimum heating power of the burner in the N + 1-section heating mode.
In some embodiments of the present application, in a case that the maximum heating power of the burner in the N-section heating mode is equal to the minimum heating power of the burner in the N + 1-section heating mode, when the burner is at the minimum heating power in the N + 1-section heating mode, if the load of the gas water heater is reduced, the gas water heater performs the N-section heating mode.
Specifically, when the heating power of the two continuous heating modes is continuously transited during programming of the gas water heater, the electric heating module does not need to be started when the load is reduced and the heating mode is switched from the N +1 heating mode to the N heating mode.
In another embodiment, if the maximum heating power of the burner in the N-section heating mode is less than the minimum heating power of the burner in the N + 1-section heating mode, then when the burner is at the minimum heating power in the N + 1-section heating mode, if the load of the gas water heater is reduced, the gas water heater performs the N-section heating mode and simultaneously starts the electric heating module.
Specifically, when the gas water heater is programmed, and the heating power of the two continuous heating modes is not continuously transited, when the load is reduced and the N +1 heating mode is switched to the N heating mode, the burner is at the maximum heating power of the N heating mode, and the electric heating module is powered on to perform auxiliary heating.
Meanwhile, in an embodiment of the present application, the control method of the gas water heater further includes: in the N-section heating mode, when the load of the gas water heater is reduced, the heating power of the electric heating module is firstly reduced, and after the electric heating module is closed, the heating power of the burner is reduced.
Specifically, in the N-segment heating mode, if the load is reduced, the heating power of the electric heating module is first reduced to meet the load reduction requirement. And after the electric heating module is closed, the load is continuously reduced, and the heating power of the burner is correspondingly reduced.
In one embodiment, in order to effectively reduce the noise generated during the operation of the gas water heater, the gas water heater is further provided with a noise detector 500, and the noise detector 500 can send a signal for detecting the noise to the control device 400. When the gas water heater is running, the control device 400 controls the gas water heater according to the control program of the gas water heater, which is stored in the memory and can be executed by the processor, and the specific control method further includes:
acquiring noise generated in the operation process of the gas water heater, and judging whether the acquired noise value is within a set noise range; if the temperature is within the set noise range, keeping the heating quantity of a burner and an electric heating module in the gas water heater unchanged; and if the noise value exceeds the set noise range, adjusting the heating quantity of a burner and an electric heating module in the gas water heater until the obtained noise value is within the set noise range.
Specifically, after the gas water heater is powered on and started, the noise detector 500 may detect noise generated during the operation of the gas water heater in real time, and the noise detector 500 may send the detected noise value to the control device 400. After receiving the noise value signal transmitted from the noise detector 500, the control device 400 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. When the processor in the control device 400 analyzes and judges that the operating noise of the gas water heater is within the stored noise range, the processor indicates that the operating parameters of the gas water heater are appropriate, and then the processor continues to keep the operating parameters running. When the processor in the control device 400 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 100 and the electric heating module 300 to adjust the operating parameters. And, in the process of adjusting the operating parameters of the burner 100 and the electric heating module 300, the noise is monitored in real time by cooperating with the noise detector 500 until the acquired noise value is within the set noise range.
In other embodiments, the specific adjustment of the operating parameters of the burner 200 and of the electrical heating module 400 may be carried out according to the magnitude of the noise values obtained, as follows.
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.
In the third embodiment, as shown in fig. 4 to 5, there are at least two ways for the water flow connection location of the electric heating module 400.
In the first mode, the electric heating module 400 is connected between the water inlet pipe and the heat exchanger 300; in the second mode, the electric heating module 400 is connected between the heat exchanger 300 and the water outlet pipe.
In the present embodiment, the electric heating module 400 is connected between the water outlet pipe and the heat exchanger 300.
Cold water delivered by a water supply pipe in the home of the user enters the water inlet pipe, enters the electric heating module 400 after passing through the heat exchanger 300, and finally water flowing out of the electric heating module 400 is output through the water outlet pipe 102.
In one embodiment, to facilitate the connection of the pipes, the water inlet pipe 101 is provided with a first connection pipe 1011, and the water inlet pipe 101 is connected with the heat exchanger 300 through the first connection pipe 1011; the water outlet pipe 102 is provided with a second connecting pipe 1021, and the water outlet pipe 102 is connected with the heat exchanger 300 through the second connecting pipe 1021; a bypass pipe 1000 is provided between the first connection pipe 1011 and the second connection pipe 1021.
Specifically, during actual use, the water outputted from the heat exchanger 300 flows into the electric heating module 400 through the second connection pipe 1021 and is finally outputted from the water outlet pipe. When the water is switched on and off for a short time, the temperature of the water outputted from the heat exchanger 300 is high, and a part of cold water is introduced into the second connection pipe 1021 from the bypass pipe 1000, so that the cold water and the hot water are mixed, thereby reducing the occurrence of a situation that the temperature of the water is greatly increased.
In order to avoid that the bypass pipe 1000 supplies excessive cold water to the second connection pipe 1021 in the normal heating process, the pipe diameter of the bypass pipe 1000 is smaller than the pipe diameters of the first connection pipe 1011 and the second connection pipe 1021.
Specifically, when the user turns off the water for a short time and starts the water supply again, and the water flow flowing in from the water inlet pipe is conveyed to the heat exchanger 300 and the bypass pipe 1000 through the first connecting pipe 1011, the heat exchange pipeline in the heat exchanger 300 is in a coil shape, so that the water resistance at the initial stage of the water flow is large, and further more cold water can enter the second connecting pipe 1021 through the bypass pipe 1000; and the water heated again in the heat exchanger 300 can be effectively cooled by the cold water after flowing into the second connection pipe 1021, so as to reduce the fluctuation of the water temperature.
During normal heating, most of the water conveyed by the first connecting pipe 1011 enters the heat exchanger 300 to be heated due to the small pipe diameter of the bypass pipe 1000, so that the requirement of normal heating is met.
In addition, as for the pipe arrangement of the first connection pipe 1011, the second connection pipe 1021 and the bypass pipe 1000, the first connection pipe 1011 and the second connection pipe 1021 may be arranged at the same side of the heat exchanger 300, and the bypass pipe 1000 may also be arranged at the side of the heat exchanger 300. Alternatively, the first connection pipe 1011 is disposed at one side of the heat exchanger 300, the second connection pipe 1021 is disposed at the other side of the heat exchanger 300, and the bypass pipe 1000 is located below the combustor 200.
And for the requirement of a compact design, the control device 500 is also disposed inside the casing 100, the control device 500 being provided at the side of the burner 200. Specifically, a space is left between the burner 200 and the sidewall of the casing 100 to install the control device 500. In order to avoid the influence of the heat generated by the gas combustion of the burner 200 on the electrical components in the control device 500, a shielding plate 501 is further disposed between the control device 500 and the burner 200. The protection plate 501 is shielded between the control device 500 and the burner 200, and can perform a heat insulation function on the control device 500.
In the fourth embodiment, the electric heating module 400 has various physical forms, and the following description is given by way of example with reference to the accompanying drawings.
In one embodiment, to achieve the requirement of instantaneous heating of the electric heating module 400, as shown in fig. 6-8, the electric heating module 400 includes:
a first electric heating member 21 for generating heat by energization of the first electric heating member 21;
the outer sleeve 22, the outer sleeve 22 is provided with a water inlet 221;
an inner tube 23, one end of the inner tube 23 is provided with a water outlet 231, and the other end is provided with an auxiliary inlet 232;
a helical plate 25, the helical plate 25 being disposed around the inner cannula 23 and extending along the length of the inner cannula 23.
Wherein the inner cannula 23 is sealingly inserted into the outer cannula 22, the auxiliary inlet 32 is located inside the outer cannula 22, and the first electric heating element 21 is arranged on the outer cannula 22 and is used for heating the water in the outer cannula 22.
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 first electric heating member 21, and the heated water flows into the inner socket 23 via the auxiliary inlet 32 and is output from the inner socket 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.
In other embodiments, there are a plurality of ways for the first electric heating part 21 to be embodied. For example: conventional electrical heating methods are classified into an electrical heating tube and a thick film heating, which are exemplified below.
In one embodiment, the first electric heating element 21 is a thick film wrapped outside the outer sleeve 22, and the outer sleeve 22 is a heat conducting pipe. Specifically, the first electric heating element 21 is a thick film, which can be wrapped around the outer sleeve 22. correspondingly, the outer sleeve 22 is made of a material (e.g., copper tube or aluminum tube) with excellent thermal conductivity. When the thick film is electrically heated, heat is transferred to the interior through the outer sleeve 22 to heat the water flowing between the outer sleeve 22 and the inner insert 23.
Preferably, for heat preservation, a heat preservation shell 26 may be disposed outside the first electric heating member 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 may also protect the first electric heating member 21 from outside, so as to improve reliability and safety in use.
In another embodiment, the first electric heating part 21 may be an electric heating pipe located between the outer sleeve 22 and the inner sleeve 23 to directly heat water flowing therethrough inside. Alternatively, the electric heating tube is wound on the outside of the outer sleeve 22, and the electric heating tube generates heat and transfers the heat through the outer sleeve 22.
In some embodiments, in order to facilitate the detection of the temperature, a temperature detector 27 may be disposed at the end of the outer sleeve 22 away from the water inlet 221, the temperature detector 27 being close to the auxiliary inlet 32 of the inner sleeve 23, and the temperature of the water flowing into the inner sleeve 23 is detected to control the heating power of the first electric heating element 21. After the water flow reversely flows into the inner insertion tube 23, the water flowing through the inner insertion tube 23 can still be adjusted by the water temperature in the outer sleeve during the outflow process, and further the heating power of the first electric heating element 21 is further adjusted according to the temperature of the water flow flowing into the inner insertion 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.

Specifically, water introduced into the gas water heater flows into the heating container 11 through the first water pipe 114, and the water introduced into the heating container 11 is heated by the energization of the second electric heating member 12.
