In order to meet the design requirement of miniaturization and compactness, the mounting position of the electric heater 400 can be arranged at the back of the combustion chamber 200, and particularly, a certain interval needs to be reserved between the combustion chamber 200 and the back of the shell to reduce the direct heat transfer of the combustion chamber 200 to the shell. In the case of the electric heater 400, the electric heater 400 is installed using a space formed between the combustion chamber and the back of the case. Thus, the electric heater 400 can be mounted by fully utilizing the space inside the housing, and the whole structure is more compact.
In the case of an electric auxiliary combustion-supporting gas water heater using gas as an energy source, components such as a fan 103 and a water pump 104 are disposed in a housing in addition to a combustion chamber 200 and a heat exchanger 300, and the heat exchanger 300 is disposed above the combustion chamber 200 in a conventional layout manner, and components such as the fan 103 and the water pump 104 are disposed below the combustion chamber 200.

In the present embodiment, the electric heater 400 is connected between the water outlet pipe and the heat exchanger 300. Cold water delivered by a water supply pipe in the user's home enters the water inlet pipe, passes through the heat exchanger 300 and then enters the electric heater 400, and finally water flowing out of the electric heater is output through the water outlet pipe.

Specifically, the electric heating pipe 2 is arranged side by side with the heating water pipe 1, and the electric heating pipe 2 extends the extension track of the heating water pipe 1. Wherein, the heating water pipe 1 can be made of materials with good heat conductivity, such as copper pipes or aluminum pipes, etc., and the electric heating pipe 2 is attached to the heating water pipe 1 to improve the heat transfer efficiency between the two.

Preferably, the heat insulator 100 is a housing structure, the heating water pipe 1 is attached to the combustion chamber, and the heat insulator 100 covers the heating water pipe 1 and the electric heating pipe 2.
Specifically, the heat insulator 100 is covered on the back of the combustion chamber by a cover structure and covers the heating water pipe 1 and the electric heating pipe 2, so that on one hand, the heating water pipe 1 can be attached to the combustion chamber to absorb heat generated by combustion of gas, and on the other hand, the heat insulator 100 can reduce heat loss of the electric heating pipe 2 and simultaneously play a role in isolating heat transfer between the outer shell and the electric heating pipe 2.
In some embodiments, the electric control component of the electric auxiliary combustion-supporting gas water heater is placed in the electric control box 500, and the electric component may be a component such as an electric control board disposed in the electric control box 500, wherein the electric control board is used to control the operation of the combustion chamber 200 and the electric heater 400, and the specific configuration inside the electric control box 500 is not limited and will not be described herein.
And the electronic control box 500 is also arranged inside the housing for the requirement of a miniaturized design, and the electronic control box 500 is arranged at the side of the combustion chamber 200. Specifically, the combustion chamber 200 and the side wall of the housing have a free space therebetween for installing the electronic control box 500. In order to prevent the heat generated by the combustion of the gas in the combustion chamber 200 from affecting the electrical components in the electronic control box 500, a shielding plate (not shown) is further disposed between the electronic control box 500 and the combustion chamber 200. The protection plate is shielded between the electronic control box 500 and the combustion chamber 200, and can play a role in heat insulation for the electronic control box 500.
In the second embodiment, as shown in fig. 1, 4-9, a flow regulating valve 600 may be further disposed between the water inlet pipe 101 and the heat exchanger 300.
Specifically, the flow regulating valve 600 includes: a valve body 31 and a valve spool 32.
The valve body 31 is provided with a water inlet flow passage 311 and a water outlet flow passage 312, the valve body 31 is also internally provided with a water inlet cavity 310, the valve body 31 is also provided with an installation opening 313 communicated with the water inlet cavity 310, the water outlet flow passage 312 is formed in the water inlet cavity 310 to form an extension pipe part 314 extending towards the direction of the installation opening 313, the pipe orifice of the extension pipe part 314 is provided with a notch 3141, and the extension pipe part 314 and the water inlet flow passage 311 are respectively communicated with the water inlet cavity 310;
the valve body 32 includes a driving member 321 and a valve plate 323, the valve plate 323 is disposed on the driving member 321, the driving member 321 is sealingly disposed on the mounting port 313, and the driving member 321 is configured to drive the valve plate 323 toward or away from the extension pipe portion 314 to selectively open and close the extension pipe portion 314 by the valve plate 323.
In actual use, the valve body 31 is connected between the heat exchanger 300 and the water inlet pipe 101 in the gas water heater, water conveyed by a tap water pipe enters the water inlet channel 311 of the valve body 31 through the water inlet pipe 101, and water flows into the water inlet cavity 310 and is output from the water outlet channel 312 into the heat exchanger 300 through the extension pipe part 314. An electric heater 400 is also provided in the gas water heater, and water flowing out of the water outlet pipe also flows through the electric heater 400.
When the water is heated by the heat exchanger, the driving member 321 drives the valve plate 323 away from the nozzle of the extension pipe portion 314 to fully open the flow regulating valve, and the flow of the water introduced from the tap water pipe is not restricted from entering the heat exchanger for heating.
When water needs to be heated by the electric heater 400 alone, a large water flow rate cannot be heated to a set temperature because the heating power of the electric heater 400 is small. At this time, the driving part 321 drives the valve plate 323 to approach the orifice of the extension pipe portion 314 to close the flow regulating valve; since the opening 3141 is formed in the nozzle of the extension pipe portion 314, the valve plate 323 does not close the opening 3141, so that the water in the water inlet cavity 310 can flow into the extension pipe portion 314 from the opening 3141 and output a certain flow of water from the water outlet flow passage 312, thereby restricting the flow of water. In this way, a lower flow of water enters the electric heater 400, and the electric heater 400 is able to heat the water flow to a desired temperature output to meet the user's demand for hot water.
In some embodiments, the surfaces of the valve plate 323 opposite the extension pipe portion 314 form sealing surfaces for a good seal against the orifice of the extension pipe portion 314. Specifically, after the valve plate 323 abuts on the extension pipe portion 314, the nozzle of the extension pipe portion 314 is sealed with the sealing surface formed by the valve plate 323.
In some embodiments, the drive member 321 may take a variety of physical forms, as exemplified below.
In order to meet the requirement of miniaturization, the driving member 321 comprises a flange 3211, a coil 3212, an iron core 3213 and a spring 3214, wherein the coil 3212 is disposed on the flange 3211, the iron core 3213 is slidably disposed in the coil 3212, the spring 3214 is disposed between the iron core 3213 and the flange 3211, the valve plate 323 is disposed on the iron core 3213, and the flange 3211 is hermetically disposed on the mounting opening 313.
Specifically, the driving member 321 is electromagnetically driven, and the coil 3212 is energized to drive the iron core 3213 to drive the valve plate 323 to move, so as to close the nozzle of the extension pipe portion 314. After the coil 3212 is de-energized, the iron core 3213 drives the valve plate 323 to move reversely to extend the nozzle of the tube 314 under the action of the spring 3214.
In one embodiment, in order to ensure that the notch 3141 ensures a desired flow rate of water into the extension pipe portion 314 after the valve plate 323 closes the orifice of the extension pipe portion 314, the water inflow direction of the notch 3141 is offset from the center line of the extension pipe portion 314 with respect to the notch 3141.
Specifically, when water in the water inlet cavity 310 enters the extension pipe portion 314 through the notch 3141, because the two side walls of the notch 3141 are arranged in a manner of deviating from the central line of the extension pipe portion 314, after the water enters the extension pipe portion 314 from the notch 3141, a rotational flowing water flow is formed in the extension pipe portion 314, so that the water flow introduced by the notch 3141 at different positions can not generate additional water resistance, and the water flow is further improved.
In another embodiment, the outlet direction of the inlet channel 311 is toward the outer wall of the extension pipe portion 314.
Specifically, the valve body 31 has a three-way structure, and water supplied to the water inlet channel 311 enters the water inlet chamber 310, and flows through the water inlet chamber 310 from the extension pipe 314 into the water outlet channel 312 and is finally discharged.
The water flow introduced into the water inlet passage 311 flows toward the outer wall of the extension pipe portion 314, and is uniformly divided by the obstruction of the extension pipe portion 314. Thus, after the valve plate 323 closes the nozzle of the extension pipe portion 314, the water flow can be uniformly distributed in the water inlet cavity 310, and further, the water can be uniformly supplied into the extension pipe portion 314 through the notches 3141 at different positions of the nozzle of the extension pipe portion 314.
In the preferred embodiment, the outer wall of the extension pipe portion 314 is further provided with a water blocking rib 3142.
Specifically, because the pipe orifice of the extension pipe portion 314 is suspended in the water inlet cavity 310, the water flow introduced from the water inlet channel 311 flows towards both sides after impacting the outer wall of the extension pipe portion 314, and slows down the water flow under the action of the water blocking rib 3142, so that the water in the water inlet cavity 310 can enter the extension pipe portion 314 through the notches 3141 at different positions.
The extension pipe 314 has two water blocking ribs 3142, and the two water blocking ribs 3142 are disposed on two sides of the outlet of the water inlet channel 311.
Specifically, the water blocking ribs 3142 are arranged on two sides of the extension pipe part 314, and the water blocking ribs 3142 block the water flow output by the water inlet channel 311 on two sides of the extension pipe part 314, so that the water flow is uniformly distributed on the periphery of the extension pipe part 314, and the situation that the water inflow is uneven due to the fact that the water inflow impacts the notches 3141 at different positions is reduced.
In some embodiments, a self-generating mechanism 33 for generating electricity using the inflow water is further disposed in the inflow channel 311.
Specifically, the self-generating mechanism 33 is disposed in the water inlet 311, the self-generating mechanism 33 generates power by using the water flowing in the water inlet 311, and the self-generating mechanism 33 can supply power to relevant electrical components in the gas water heater as required by using the electric energy generated by the water flow.
For example: the valve body 31 is further provided with a flow sensor (not shown) which detects the flow of water flowing through the valve body, and the self-generating mechanism 33 can supply power to the flow sensor.
Alternatively, a water temperature sensor (not shown) is provided on a pipe wall of the valve body 31, the water temperature sensor can detect the temperature of the water flowing through the valve body 31, and the self-generating mechanism 33 can supply power to the water temperature sensor.
For the structural forms of the water temperature sensor and the flow sensor, the sensor form in the conventional technology can be adopted, and is not limited and described herein.
In some embodiments, the self-generating mechanism 33 includes a generator 331, a water wheel 332, and a mounting bracket 333, the mounting bracket is disposed in the water inlet flow passage 311, the generator 331 is disposed on the mounting bracket 333, and the water wheel 332 is disposed on a rotating shaft of the generator 331.
Specifically, the generator 331 is installed in the water inlet flow passage 311 through the installation support 333, and the installation support 333 can meet the installation requirements of the generator 331 and can reduce water resistance to water flow. The water wheel 332 is installed on the generator 331, and the water flowing through the water inlet channel 311 drives the water wheel 332 to rotate so as to drive the generator 331 to generate electricity.
Preferably, the mounting bracket 333 has a cylindrical structure as a whole, a plurality of support rods 3331 are provided at one port of the mounting bracket 333, and the generator 331 is disposed between the support rods 3331. The supporting rod 3331 can meet the installation requirement of the generator 331, and the supporting rod 3331 can reduce the resistance to the water flow to the maximum extent.
Furthermore, in order to improve the power generation efficiency of the water flow, a plurality of guide plates 3332 are arranged at the other end of the mounting bracket 333, the plurality of guide plates 3332 are arranged obliquely around the center line of the mounting bracket 333, the water flowing through the water inlet channel 311 is guided by the guide plates 3332 to form a rotational flowing water flow, and the rotational flowing water flow enters the mounting bracket 333 to impact the water wheel 332 to rotate, so that the power generation efficiency can be improved more effectively.
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.
