[0065] In general, when the integrated water channel module 40 is in use, the water inlet 100 of the integrated water channel module 40 is connected to the first heat exchange flow channel outlet 13 of the first heat exchanger and / or the water outlet 91 of the indoor heating device, and the water return port 300 of the integrated water channel module 40 is connected to the first heat exchange flow channel inlet 14 of the first heat exchanger and / or the water inlet 92 of the indoor heating device. The water after heat exchange in the first heat exchanger 10 and / or the water output from the water outlet 91 of the indoor heating device can be delivered to the external heat source 30 through the water outlet 200 of the integrated water channel module 40.

[0067] Moreover, the integrated water channel module 40 has a more compact structure through its integrated design, so that the integrated water channel module 40 can be integrated and arranged on one side of the first heat exchanger 10, and then the first heat exchanger 10 can be more conveniently connected to the external heat source 30 and perform heat exchange through the integrated water channel module 40 without setting up an external pipeline module, thereby solving the problems of complex pipelines and low integration, and also making it easier to disassemble and assemble the integrated water channel module 40 and the external heat source 30, thereby improving the disassembly and assembly efficiency.

[0068] In a feasible embodiment of the present invention, the water inlet 100 is used to connect to the first heat exchange channel outlet 13 of the first heat exchanger, the return water port 300 is used to connect to the water inlet 52 of the combustion heat exchange device, the water outlet 200 is used to transport the water after heat exchange in the first heat exchanger 10 to the external heat source 30, and the return water port 300 is used to input the water heated by the external heat source 30 into the water inlet 52 of the combustion heat exchange device and heat the water in the combustion heat exchange device 50 and then transport it to the first heat exchange channel 11 of the first heat exchanger through the water outlet 51 of the combustion heat exchange device.

[0069] In another feasible embodiment of the present invention, the water inlet 100 is used to connect to the water outlet 91 of the indoor heating equipment, the return water port 300 is used to connect to the water inlet 52 of the combustion heat exchange device, the water outlet 200 is used to transport the water output from the water outlet 91 of the indoor heating equipment to the external heat source 30, and the return water port 300 is used to input the water heated by the external heat source 30 into the water inlet 52 of the combustion heat exchange device and heat the water through the combustion heat exchange device 50 and then transport it to the indoor heating equipment 90 through the water outlet 51 of the combustion heat exchange device.

[0070] In another feasible embodiment of the present invention, the water inlet 100 is used to connect the first heat exchange channel outlet 13 of the first heat exchanger and the water outlet 91 of the indoor heating equipment, the return water port 300 is used to connect the water inlet 52 of the combustion heat exchange device, the water outlet 200 is used to transport the water after heat exchange by the first heat exchanger 10 and the water output from the water outlet 91 of the indoor heating equipment to the external heat source 30, and the return water port 300 is used to input the water heated by the external heat source 30 into the water inlet 52 of the combustion heat exchange device and heat the water by the combustion heat exchange device 50 and then transport it to the first heat exchange channel 11 of the first heat exchanger and the indoor heating equipment 90 through the water outlet 51 of the combustion heat exchange device.

[0071] In the embodiments of the present invention, designers can adjust the specific structure of the first heat exchanger 10 according to usage needs and are not specifically limited here. Preferably, the first heat exchanger 10 is a plate heat exchanger. The first heat exchange channel 11 and the second heat exchange channel 12 of the first heat exchanger are two independent waterways, so that the domestic water to be heated in the second heat exchange channel 12 of the first heat exchanger can only exchange heat with the heating medium in the first heat exchange channel 11 of the first heat exchanger.

[0072] In the implementation manner of the present invention, designers can adjust the specific structure of the indoor heating device 90 according to usage needs. For example, the indoor heating device 90 is a heater, and no specific limitation is made here.

[0073] In the embodiment of the present invention, the preset state is that the valve member 400 is in the conducting state. By switching the valve member 400 to the preset state, water entering from the water inlet 100 is allowed to flow to the water outlet 200 and / or the water return port 300 .

[0074] The designer can control the preset state of the valve member 400 according to usage requirements, and no specific limitation is imposed herein. For example, the valve member 400 may allow water entering the water inlet 100 to flow only to the water outlet 200, or may allow water entering the water inlet 100 to flow only to the water return port 300, or may allow water entering the water inlet 100 to flow to both the water outlet 200 and the water return port 300.

[0075] Furthermore, by controlling the opening of the valve member 400 , the flow in the water outlet 200 and the water return port 300 can be controlled, which provides better adjustment convenience and adjustment accuracy.

[0076] The designer can adjust the specific structure of the valve member 400 according to the use requirements, and no specific limitation is imposed here. Preferably, the valve member 400 is a three-way control valve 500. More preferably, the valve member 400 is a solenoid valve.

[0077] In an embodiment of the present invention, the integrated water channel module 40 further includes a first channel provided between the water inlet 100 and the water outlet 200 , and a second channel provided between the water inlet 100 and the water return port 300 .

[0078] The water entering through the water inlet 100 can be transported to the water outlet 200 through the first channel, and then the water outlet 200 can output the water to be heated to the external heat source 30 for external heating.

[0079] In addition, the water entering through the water inlet 100 can be transported to the return water port 300 through the second channel. Since the return water port 300 is connected to the water inlet 52 of the combustion heat exchange device, this part of the water can enter the water inlet 52 of the combustion heat exchange device and be heated by the combustion heat exchange device 50 before being transported to the first heat exchange channel 11 of the first heat exchanger and / or the indoor heating equipment 90 through the water outlet 51 of the combustion heat exchange device.

[0080] Furthermore, through the cooperation of the first channel and the second channel, part of the water entering through the water inlet 100 is transported to the water outlet 200 and output to the external heat source 30 for external heating, and the remaining water entering through the water inlet 100 is transported to the return water port 300 and output to the water inlet 52 of the combustion heat exchange device. After the water is heated by the combustion heat exchange device 50, it is transported to the first heat exchange channel 11 of the first heat exchanger and / or the indoor heating equipment 90 through the water outlet 51 of the combustion heat exchange device, thereby achieving the effect of external heating of part of the water and improving the flexibility of use of the integrated water channel module 40.

[0081] In the embodiment of the present utility model, as Figure 1 and Figure 2 In the illustrated embodiment, the integrated water channel module 40 includes a tee 500 having a first port, a second port, and a third port. The first port is connected to the water inlet 100, the second port is connected to the return water port 300, and the third port is used to connect to the water inlet 52 of the combustion heat exchange device. The valve member 400 is arranged in a portion of the second channel between the water inlet 100 and the first port, and the valve member 400 can controllably connect the first channel and the second channel.

[0082] By disposing the valve member 400 on a portion of the second channel between the water inlet 100 and the first port, the valve member 400 controllably connects the first channel and the second channel. Furthermore, the water inlet 100, the water return port 300, and the water inlet 52 of the combustion heat exchanger are connected via the tee 500. Water heated by the external heat source 30 enters the second channel through the water return port 300 and is transported to the water inlet 52 of the combustion heat exchanger via the tee 500.

[0083] Alternatively, the water entering through the water inlet 100 flows into the second channel and can be directly transported to the water inlet 52 of the combustion heat exchange device by means of the tee 500 .

[0084] In the embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 4 In the embodiment shown, the integrated water circuit module 40 also includes an inlet pipe 610, an outlet pipe 620 and a return pipe 630. The valve member 400 controllably connects the inlet pipe 610, the outlet pipe 620 and the return pipe 630. The inlet of the inlet pipe 610 forms a water inlet 100, the outlet of the outlet pipe 620 forms a water outlet 200, and the inlet of the return pipe 630 forms a return water port 300. The tee 500 is arranged on the return pipe 630. The inlet of the first pipe 640 is connected to the third port, and the outlet of the first pipe 640 is used to communicate with the water inlet 52 of the combustion heat exchange device.

[0085] Specifically, the water outlet pipe 620 forms at least a portion of the first channel, and the water return pipe 630 forms at least a portion of the second channel. Furthermore, the third port can be connected to the water inlet 52 of the combustion heat exchanger via the first pipe 640. Thus, water in the water return pipe 630 can enter the water inlet 52 of the combustion heat exchanger via the first pipe 640. After being heated by the combustion heat exchanger 50, the water is then delivered to the first heat exchanger 10 and / or the indoor heating device 90 via the water outlet 51 of the combustion heat exchanger.

[0086] In the embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 4 In the illustrated embodiment, the inlet of the water inlet pipe 610, the outlet of the water outlet pipe 620 and the inlet of the return water pipe 630 are arranged downward, and the outlet of the first pipe 640 is arranged upward.

[0087] By setting the inlet of the water inlet pipe 610, the outlet of the water outlet pipe 620 and the inlet of the return pipe 630 downward, and setting the outlet of the first pipe 640 upward, the integrated heat exchange module is arranged as a whole in the height direction, so that the inlet of the water inlet pipe 610, the outlet of the water outlet pipe 620 and the inlet of the return pipe 630 can be arranged on the same side, which helps to improve the integration of the integrated heat exchange module and facilitates the subsequent installation and connection of the pipe mouths.

[0088] Furthermore, arranging the integrated heat exchange module along the height direction is also beneficial to reducing the radial dimension of the integrated heat exchange module, so that the integrated heat exchange module can be integrated on one side of the first heat exchanger 10 .

[0089] Furthermore, the outlet of the return pipe 630 is set upward and connected to the valve component 400, the inlet of the outlet pipe 620 is set horizontally and connected to the valve component 400, the outlet of the inlet pipe 610 is set upward and connected to the valve component 400, and the inlet of the first pipe 640 is set downward and connected to the tee 500.

[0090] Of course, designers can adjust the specific setting directions of the return pipe 630, the outlet pipe 620 and the inlet pipe 610 according to usage needs, and no specific restrictions are made here.

[0091] From the above, it can be seen that the outlet of the first pipeline 640 is set upward and the inlet of the return pipeline 630 is set downward, and the outlet of the return pipeline 630 is set upward and connected to the valve component 400, so that the return pipeline 630 and the first pipeline 640 are arranged along the height direction.

[0092] When the return water pipe 630 and / or the first pipe 640 need to be disassembled, the return water pipe 630 needs to be pulled downward to separate it from the valve member 400, and then the return water pipe 630 and the first pipe 640 can be taken out from the shell 80 of the first heat exchanger 10 for inspection.

[0093] However, when the return water pipe 630 and the first pipe 640 are vertically installed on one side of the first heat exchanger 10 and placed in the shell 80, they are easily restricted by the internal space of the shell 80, so that the overall structure formed by the return water pipe 630 and the first pipe 640 cannot move downward in the shell 80, resulting in the return water pipe 630 being unable to quickly detach from the valve component 400, thereby causing inconvenience in disassembly and assembly.

[0094] In order to solve the above problems, in the embodiment of the present utility model, Figure 1 and Figure 3 In the embodiment shown, the return water pipe 630 includes a first return water pipe section 631 and a second return water pipe section 632. The first return water pipe section 631 is connected to the water inlet 100, and the second return water pipe section 632 is connected to the return water port 300. The second return water pipe section 632 is extended in the height direction, and the first return water pipe section 631 and the second return water pipe section 632 are detachably connected.

[0095] The first water return pipe section 631 and the second water return pipe section 632 are detachably connected so that the first water return pipe section 631 and the second water return pipe section 632 can be separated. By first removing the second water return pipe section 632, a certain space is reserved in the housing 80, allowing the integrated structure consisting of the first water return pipe section 631 and the first pipeline 640 to move downward in the housing 80, thereby allowing the first water return pipe section 631 to be separated from the valve member 400, thereby facilitating the removal of the return pipe 630 and the first pipeline 640.

[0096] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 In the embodiment shown, a plug-in structure 700 is provided between the first return water pipe section 631 and the second return water pipe section 632. The plug-in structure 700 includes a slot 710 formed at one end of the first return water pipe section 631 and a plug-in portion 720 formed at one end of the second return water pipe section 632. The slot 710 and the plug-in portion 720 are detachably plugged into each other.

[0097] Furthermore, in order to avoid leakage at the joint between the first water return pipe section 631 and the second water return pipe section 632 , in an embodiment of the present invention, a sealing structure is provided between the slot 710 and the plug-in portion 720 .

[0098] Designers can adjust the specific structure of the sealing structure according to the use requirements, and no specific limitation is given here. For example, the sealing structure includes a sealing member provided between the slot 710 and the plug-in portion 720 .

[0099] Implementation Method 2

[0100] Please refer to Figure 6 As shown, an embodiment of the present invention provides a gas water heater, which includes a housing 80, a combustion heat exchange device 50, a first heat exchanger 10, and the integrated water circuit module 40 described in Embodiment 1. The specific structure, operating principle, and beneficial effects of the integrated water circuit module 40 are the same as those in Embodiment 1 and will not be repeated here.

[0101] In an embodiment of the present utility model, the gas water heater also includes a water pump 60, the inlet of the water pump 60 is connected to the first heat exchange channel outlet 13 of the first heat exchanger and / or the water outlet 91 of the indoor heating equipment, and the outlet of the water pump 60 is connected to the water inlet 100. The water pump 60 is used to deliver the water in the first heat exchange channel 11 of the first heat exchanger and / or the indoor heating equipment 90 to the water inlet 100.

[0102] The water pump 60 can drive the water flow and control the water flow rate, so that the water pump 60 can pump water from the first heat exchange flow channel outlet 13 of the first heat exchanger to the water inlet 100. Designers can adjust the specific structure of the water pump 60 according to usage needs and are not specifically limited here.

[0103] In the embodiment of the present utility model, as Figure 1 、 Figure 4 and Figure 5In the embodiment shown, the gas water heater includes a return water pipe 630, which includes a first return water pipe section 631 and a second return water pipe section 632. The second return water pipe section 632 is extended in the height direction, and the first return water pipe section 631 and the second return water pipe section 632 are detachably plugged into each other; the gas water heater also includes a limiting hole 81 provided on the shell 80, and a limiting member 6321 provided on the second return water pipe section 632. The limiting member 6321 has: an installation position that is connected to the limiting hole 81 for limiting, and a disassembly position for releasing the limiting position from the limiting hole 81.

[0104] By setting a limiting hole 81 on the shell 80 and a limiting member 6321 on the second return water pipe section 632, when the limiting member 6321 is in an installation position where it is limited by the limiting hole 81, the limiting hole 81 and the limiting member 6321 cooperate to limit the second return water pipe section 632, so that the second return water pipe section 632 can be fixed in the shell 80.

[0105] When the limiting member 6321 is in the disassembly position where the limiting position with the limiting hole 81 is released, the limiting effect of the limiting hole 81 and the limiting member 6321 is released, so that the second return water pipe section 632 can be removed from the shell 80, thereby facilitating the disassembly of the first pipeline 640 and the first return water pipe section 631.

[0106] Specifically, the limiting member 6321 includes a limiting block disposed on the second water return pipe segment 632. The second water return pipe segment 632 rotates to drive the limiting block to switch between an installed position and a removed position. When the limiting block is in the removed position, the second water return pipe segment 632 and the limiting block can be removed from the housing 80 through the limiting hole 81. Designers can adjust the specific shapes and configurations of the limiting block and limiting hole 81 according to usage requirements and are not specifically limited here.

[0107] In an embodiment of the present invention, a control module is further included. The control module is electrically connected to the valve component 400 of the integrated waterway module 40 . The control module has a working mode and a monitoring mode for controlling the valve component 400 .

[0108] When the water temperature in the first pipeline 640 is lower than the water temperature in the return pipeline 630 , the control module enters the working mode, and the valve 400 is adjusted to a first preset opening to output a first flow of water from the water outlet 200 .

[0109] When the water temperature in the first pipeline 640 is not lower than the water temperature in the return pipeline 630, the control module enters the monitoring mode, and the valve 400 is adjusted to a second preset opening to output a second flow of water from the water outlet 200; wherein the first flow is greater than the second flow.

[0110] When the water temperature in the first pipeline 640 is lower than the water temperature in the return pipeline 630, the temperature of the water heated by the external heat source 30 is higher than the temperature of the water in the first pipeline 640. At this time, the external heat source 30 can be used to provide heat to the first heat exchanger 10. Therefore, the valve 400 is adjusted to the first preset opening to output the first flow rate of water from the water outlet 200, so that more water can be output from the water outlet 200 to the external heat source 30 for external heating.

[0111] When the water temperature in the first pipe 640 is not lower than the water temperature in the return pipe 630, the temperature of the water heated by the external heat source 30 is lower than the temperature of the water in the first pipe 640. At this time, the external heat source 30 can no longer provide heat for the first heat exchanger 10, so the valve 400 is adjusted to a second preset opening to output a second flow rate of water from the water outlet 200; wherein the first flow rate is greater than the second flow rate.

[0112] In a feasible embodiment, when the water temperature in the first pipe 640 is not lower than the water temperature in the return pipe 630, the magnitude of the second flow rate is set to zero, so that water will not be output from the water outlet 200 to the external heat source 30, thereby avoiding the water passing through the external heat source 30 from flowing back from the return port 300 and lowering the water temperature in the first pipe 640.

[0113] In another feasible embodiment, the magnitude of the second flow rate is not zero, so that part of the water will be output from the water outlet 200 to the external heat source 30, and the water passing through the external heat source 30 will flow back to the first pipeline 640 from the return water port 300. At this time, by measuring the temperature of this part of the water, it can be determined whether the external heat source 30 can provide heat to the first heat exchanger 10.

[0114] Furthermore, it also includes a temperature measuring mechanism, which is electrically connected to the control module. The temperature measuring mechanism is used to detect the water temperature in the first pipeline 640 and / or the return pipeline 630, and the temperature measuring mechanism includes at least one temperature measuring element.

[0115] Designers can adjust the specific structure of the temperature measuring element according to usage requirements. For example, the temperature measuring element is a temperature sensor, which is not specifically limited here.

[0116] In an embodiment of the present invention, the gas water heater further comprises a second pipeline 70, which connects the water outlet 51 of the combustion heat exchange device, the first heat exchange channel inlet 14 of the first heat exchanger and / or the water inlet 92 of the indoor heating equipment.

[0117] By providing a second pipeline 70 connecting the water outlet 51 of the combustion heat exchange device, the first heat exchange channel inlet 14 of the first heat exchanger, and / or the water inlet 92 of the indoor heating device, water heated by the combustion heat exchange device 50 can be transported through the second pipeline 70 to the first heat exchange channel inlet 14 of the first heat exchanger and / or the water inlet 92 of the indoor heating device. Furthermore, the water inlet 52 of the combustion heat exchange device is connected to the first pipeline 640. Designers can adjust the specific structure of the second pipeline 70 according to their needs and are not specifically limited here.

[0118] In an embodiment of the present invention, the integrated water channel module 40 includes a water inlet 100 , a water outlet 200 and a water return port 300 . The water inlet 100 is disposed in the housing 80 , and the water outlet 200 and the water return port 300 are plugged into the housing 80 .

[0119] The designer can adjust the position of the water inlet 100, the water outlet 200 and the water return port 300 on the housing 80 according to the use needs, and no specific restrictions are made here. Preferably, the water outlet 200 and the water return port 300 are plugged into the housing 80 and placed at the bottom of the housing 80.

[0120] Implementation Method 3

[0121] Please refer to Figure 6 As shown, a gas hot water system is provided in an embodiment of the present invention, which includes a gas hot water device as described in embodiment 2, and an indoor heating device 90, and the combustion heat exchange device 50 is used to supply heat to the first heat exchange channel 11 of the first heat exchanger and / or the indoor heating device 90.

[0122] The specific structure, operating principle, and beneficial effects of the gas water heater are the same as those in the second embodiment and will not be further described here. By utilizing the gas water heater described in the second embodiment, the gas water heater system improves integration and enables linkage between the external heat source 30, the combustion heat exchange device 50, the first heat exchanger 10, and / or the indoor heating device 90. This allows the first heat exchanger 10 to more conveniently connect to the external heat source 30 and exchange heat via the integrated water channel module 40, thereby resolving issues such as complex piping and low integration. It also facilitates assembly and disassembly of the integrated water channel module 40, improving assembly and disassembly efficiency.

[0123] In an embodiment of the present utility model, the gas hot water system also includes a second heat exchanger 20, which is arranged outside the shell 80, the first heat exchange channel inlet 24 of the second heat exchanger is connected to the water outlet 200, the first heat exchange channel outlet 23 of the second heat exchanger is connected to the return water port 300, and the second heat exchange channel 22 of the second heat exchanger is used to connect to the external heat source 30.

[0124] By connecting the first heat exchange channel inlet 24 of the second heat exchanger with the water outlet 200 and the first heat exchange channel outlet 23 of the second heat exchanger with the return water port 300, the second heat exchanger 20 is used to prevent the water between the first heat exchanger 10 and the external heat source 30 from being connected to each other, thereby avoiding the heating water in the external heat source 30 from affecting the first heat exchanger 10, which helps to improve the service life of the first heat exchanger 10.

[0125] Designers can adjust the specific structure of the second heat exchanger 20 according to usage needs and are not specifically limited here. Preferably, the second heat exchanger 20 is a plate heat exchanger, and the first heat exchange channel 21 of the second heat exchanger and the second heat exchange channel 22 of the second heat exchanger are two independent water channels, so that the first heat exchange channel 21 of the second heat exchanger and the second heat exchange channel 22 of the second heat exchanger only exchange heat.

[0126] In the embodiments of the present invention, the external heat source 30 may include a heat pump, an electric water heater, a solar water heater, an air-energy water heater, or other heat-generating devices. Designers may also adjust the specific type of the external heat source 30 based on usage requirements, and this is not a specific limitation herein. Preferably, the external heat source 30 includes a municipal pipe network for transporting heating water.
