A gas heating water heater is a water heating device for heating and supplying domestic hot water indoors. The gas heating hot water and bathroom hot water dual-purpose heating hot water boiler in the related art can realize the function of providing heating hot water and bathroom hot water, but can not realize the function of simultaneously providing heating hot water and bathroom hot water. For example, when heating is performed, heating hot water cannot be supplied, and both the heating hot water and the bathroom hot water cannot be supplied. In the related art, other gas heating water heaters can simultaneously provide bathroom hot water and heating hot water, but the bathroom hot water temperature and the heating hot water temperature are mutually influenced by one another by the same heating source, namely gas, so that the bathroom hot water temperature and the heating hot water temperature are not easy to control. Meanwhile, heat generated by bathroom and heating cannot be effectively utilized, so that heat is wasted.
Fig. 1 shows a schematic structure of a gas heating water heater in an implementation manner of the embodiment of the application.
As shown in fig. 1, an embodiment of the present application provides a gas heating water heater including a heating system 100, a bathroom system 200, and an auxiliary heat exchanger 310. The heating system 100 includes a main heat exchanger 110, a first heating return pipe 120 and a first heating outlet pipe 130 connected to the main heat exchanger 110, respectively. The sanitary system 200 includes an electric water heater 210, a first sanitary water inlet pipe 220 and a sanitary water outlet pipe 230 respectively connected with the electric water heater 210. The auxiliary heat exchanger 310 has a first water inlet end 311 and a first water outlet end 312 communicating with each other, and a second water inlet end 313 and a second water outlet end 314 communicating with each other. That is, the first water inlet end 311 and the first water outlet end 312 constitute a first fluid passage, the second water inlet end 313 and the second water outlet end 314 constitute a second fluid passage, and the fluid in the first fluid passage and the fluid in the second fluid passage can exchange heat. The first water inlet end 311 is connected to the first heating outlet pipe 130, the first water outlet end 312 is connected to the first heating return pipe 120, the second water outlet end 314 is connected to the first bathroom water inlet pipe 220, and the second water inlet end 313 is connected to the second bathroom water inlet pipe 240, so that the heating system 100 and the bathroom system 200 exchange heat by means of the auxiliary heat exchanger 310.
Thus, since the heating system 100 is heated by using the gas and the bathroom system 200 is heated by using the electric water heater 210, the heating system 100 and the bathroom system 200 each have different heating sources, and thus, the synchronization of heating and bathing can be realized. Because the heating system 100 and the bathroom system 200 can exchange heat through the auxiliary heat exchanger 310, heat generated when any one of the heating system 100 and the bathroom system 200 is operated can be utilized by the other system, and heat waste is avoided.
In some embodiments, referring to fig. 1, the gas heating water heater further includes a first switching device 410. The first switching device 410 is provided with a first switching port 411, a second switching port 412 and a third switching port 413. The first switching port 411 communicates with the outlet of the first heating outlet pipe 130, the second switching port 412 communicates with the inlet of the first water inlet end 311, and the third switching port 413 communicates with the inlet of the second heating outlet pipe 140.

At this time, the main heat exchanger 110, the first heating outlet pipe 130, the auxiliary heat exchanger 310, and the first heating return pipe 120 constitute a circulation loop, and the bathroom system 200 may use heat generated by the heating system 100 by means of the auxiliary heat exchanger 310. The first switching device 410 is in the second state, the second switching port 412 is in communication with the third switching port 413, that is, the inlet of the first water inlet 311 of the auxiliary heat exchanger 310 is in communication with the inlet of the second heating outlet pipe 140, and the second heating outlet pipe 140 can be connected to a device requiring heating at the user side. At this time, the apparatus for heating required at the user side performs heating using the heat generated from the bathroom system 200 by means of the auxiliary heat exchanger 310, and uses electric heating. The first switching device 410 is in the third state, the first switching port 411 is communicated with the third switching port 413, that is, the outlet of the first heating outlet pipe 130 is communicated with the inlet of the second heating outlet pipe 140, and the second heating outlet pipe 140 can be connected with a device requiring heating at the user side. At this time, the device for heating required by the user side directly uses the main heat exchanger 110 to perform heating, and uses gas heating. Alternatively, the first switching device 410 may be a three-way valve, which may be used to change the fluid flow direction. In this way, by providing the first switching device 410, any two of the first heating water outlet pipe 130, the first water inlet end 311 and the second heating water outlet pipe 140 can be communicated, and according to the actual situation, the three states of the first switching device 410 can be switched, so that the heat generated when any one of the heating system 100 and the bathroom system 200 is operated can be further effectively utilized.
In particular to some embodiments, referring to fig. 1, a first temperature detecting unit 610 for detecting water temperature is disposed in the second heating outlet pipe 140. In this way, by providing the first temperature detecting unit 610 in the second heating outlet pipe 140, the water temperature in the second heating outlet pipe 140 can be obtained, and the state of the gas heating water heater suitable for operation can be selected according to the water temperature, so as to realize effective heat utilization. For example, when the aforementioned heating device for the user side uses the heat generated by the bathroom system 200 to perform heating by means of the auxiliary heat exchanger 310, if the obtained water temperature in the second heating outlet pipe 140 cannot meet the user's use requirement, it is indicated that the heat generated by the bathroom system 200 obtained by the auxiliary heat exchanger 310 through heat exchange cannot meet the user's use requirement, and at this time, the first switching device 410 will switch from the second state to the third state, and the electric heating mode is changed into the gas heating mode.
In some embodiments, referring to fig. 1, the gas heating water heater further includes a second switching device 420. The second switching device 420 includes a fourth switching port 421, a fifth switching port 422, and a sixth switching port 423.

At this time, the main heat exchanger 110, the first heating outlet pipe 130, the auxiliary heat exchanger 310, and the first heating return pipe 120 constitute a circulation loop, and the bathroom system 200 may use heat generated by the heating system 100 by means of the auxiliary heat exchanger 310. The second switching device 420 is in the fifth state, and the fifth switching port 422 and the sixth switching port 423 are in communication, that is, the outlet of the first water outlet 312 of the auxiliary heat exchanger 310 is in communication with the outlet of the second heating return pipe 150, and the inlet of the second heating return pipe 150 can be in communication with the device for heating required by the user.

The second switching device 420 is in the sixth state, and the fourth switching port 421 and the sixth switching port 423 are in communication, that is, the inlet of the first heating return pipe 120 is in communication with the outlet of the second heating return pipe 150.

For example, when the second switching device 420 is in the fifth state or the sixth state, the second heating return pipe 150 is used to provide the operation power for the water flowing from the second heating return pipe 150, so that the water circulation in the corresponding operation state can be satisfied.
In some embodiments, referring to fig. 1, a second water pump 520 is disposed on the first heating return pipe 120. In this way, the water flowing in from the first heating return pipe 120 can be provided with the operation power, thereby satisfying the operation requirements in different operation states.
In some embodiments, please continue to refer to fig. 1, the bypass of the second bathroom inlet pipe 240 is connected to the bathroom return pipe 250, and the inlet of the bathroom return pipe 250 is connected to the outlet of the bathroom outlet pipe 230. Thus, by providing the bathroom return pipe 250, circulation of bathroom water in the bathroom system 200 is realized, a function of zero cold water is realized, and heat generated by running the bathroom system 200 can be further effectively utilized. In particular to some embodiments, a third water pump 530 is provided on the bathroom return 250. In this way, the water flowing in from the bathroom return pipe 250 can be provided with operation power, so that the operation requirements under different operation states can be met.

For example, when the bathroom system 200 is obtaining the heat generated by the gas heating, if the water temperature in the first bathroom inlet pipe 220 is detected to be unable to meet the user's requirement, the electric heating mode is turned on at the same time to meet the user's requirement for using the bathroom system 200. At this time, the circulation loop in the gas heating water heater will be changed correspondingly, and specific reference may be made to the content in the foregoing embodiments, which is not described herein.
In some embodiments, referring to fig. 1, a fourth temperature detecting unit 640 for detecting the water temperature is provided on the second bathroom inlet pipe 240. In this way, by providing the fourth temperature detection unit 640 in the second bathroom inlet pipe 240, the water temperature in the second bathroom inlet pipe 240 can be obtained, and the state of the gas heating water heater suitable for operation can be selected according to the water temperature, so as to realize effective heat utilization. For example, when the bathroom system 200 is obtaining the heat generated by the gas heating, if the water temperature in the second bathroom inlet pipe 240 is detected to be unable to meet the requirement, the electric heating mode is turned on at the same time to meet the requirement of the user for using the bathroom system 200. At this time, the circulation loop in the gas heating water heater will be changed correspondingly, and specific reference may be made to the content in the foregoing embodiments, which is not described herein.
In some embodiments, referring to fig. 1, a flow detection unit 710 for detecting water flow is disposed on the second toilet inlet pipe 240. In this way, by providing the flow detection unit 710 on the second bathroom inlet pipe 240, it is possible to know whether there is water flowing into the second bathroom inlet pipe 240, and to select a state in which the gas heating water heater is suitable for operation, so as to achieve effective use of heat. That is, when it is detected that water flows into the second bathroom inlet pipe 240, some circulation pipes on the auxiliary heat exchanger 310 are switched according to actual situations, and the specific switching process may refer to the content in some embodiments described above, which is not described herein.
In some embodiments, with continued reference to FIG. 1, the heating system 100 further includes a burner 160 and a fan 170. Wherein the burner 160 is used to heat hot water in the main heat exchanger 110, and the fan 170 is used to discharge exhaust gas generated from the burner 160 to the outside.
In some embodiments, referring to fig. 1, the electric water heater 210 includes a water storage tank 211, and a magnesium rod 212, a temperature measuring tube 213, and a heating tube 214 disposed in the water storage tank 211.

In some embodiments, the auxiliary heat exchanger 310 is a plate heat exchanger, and may be used to exchange heat between water in the heating system 100 and water in the toilet and bathroom system 200in the practice of the present application.
In some embodiments, with continued reference to fig. 1, the heating system 100 further includes an expansion tank 180. Due to the expansion and contraction of the water in the heating system 100, when the hot water is warmed up, the volume of the water in the heating system 100 increases, and when there is no expansion of the portion containing water, the water pressure in the heating system 100 increases, which affects normal operation. The expansion tank 180 accommodates the water expansion amount of the heating system 100, reduces the water pressure fluctuation of the heating system 100 due to the expansion of water, and improves the safety and reliability of the operation of the heating system 100. When the heating system 100 leaks water or the system cools down for some reason, the water level of the expansion tank 180 drops, and the heating system 100 is replenished with water. The expansion tank 180 may also serve to stabilize the pressure of the heating system 100 and to remove air released by the water during heating. Thus, the expansion tank 180 may be connected to the first heating return pipe 120 for accommodating an expansion amount of system water in the heating system 100, and also plays a role of fixing pressure and supplementing water to the heating system 100.
It should be noted that in some embodiments, the gas heating water heater further includes a controller (not shown in the drawings), and the controller may obtain the water temperature detected by each temperature detecting unit and whether the water passing through is detected by the flow detecting unit 710, so as to control the state switching of each water pump and each switching device, so as to implement different circulating waterways running in the gas heating water heater, so that the heat generated by each system is effectively utilized on the premise of meeting the use requirement of the user.
Therefore, the gas heating water heater provided by the embodiment of the application has four working modes for a user to select, wherein the four working modes are a heating mode, a bathroom mode, a heating-bathroom mode (namely a working mode for simultaneously providing heating hot water and bathroom hot water) and a zero cold water mode respectively.
The four modes of operation provided in the examples of the present application are further described below with reference to the implementation of some of the foregoing examples.
Referring to fig. 1, when a user selects a heating mode, the heating mode has two states of heating using gas and heating using electricity. When heating using gas, the first switching device 410 is in the third state, the first switching port 411 and the third switching port 413 are in communication, the second switching device 420 is in the sixth state, and the fourth switching port 421 and the sixth switching port 423 are in communication. The outlet of the first heating outlet pipe 130 is connected to the inlet of the second heating outlet pipe 140, the second heating outlet pipe 140 may be connected to a device for heating at the user end, and the inlet of the first heating return pipe 120 is connected to the outlet of the second heating return pipe 150. The device for heating required by the user side directly uses the main heat exchanger 110 for heating. At this time, the flow direction of the heating water is: the main heat exchanger 110- & gt the first heating water outlet pipe 130- & gt the second heating water outlet pipe 140- & gt the user- & gt the second heating water return pipe 150- & gt the first heating water return pipe 120- & gt the main heat exchanger 110. When electric heating is used, the first switching device 410 is in the second state, the second switching port 412 and the third switching port 413 are in communication, the second switching device 420 is in the fifth state, and the fifth switching port 422 and the sixth switching port 423 are in communication. The inlet of the first water inlet end 311 of the auxiliary heat exchanger 310 is communicated with the inlet of the second heating water outlet pipe 140, the outlet of the first water outlet end 312 of the auxiliary heat exchanger 310 is communicated with the outlet of the second heating water return pipe 150, the inlet of the second heating water return pipe 150 is communicated with the outlet of the device for heating the user side, the outlet of the second heating water outlet pipe 140 is communicated with the inlet of the device for heating the user side, the second water pump 520 stops running, the first water pump 510 and the third water pump 530 run, and the device for heating the user side utilizes the heat generated by the bathroom system 200 by means of the auxiliary heat exchanger 310. At this time, the flow direction of the bathroom water is: bathroom return pipe 250- & gt auxiliary heat exchanger 310- & gt first bathroom inlet pipe 220- & gt electric water heater 210- & gt bathroom outlet pipe 230- & gt bathroom return pipe 250, the flow direction of heating water is: second heating return pipe 150→auxiliary heat exchanger 310→second heating outlet pipe 140→second heating return pipe 150.
In the heating mode, the water temperature in the second heating outlet pipe 140 may be detected by the first temperature detecting unit 610. If it is detected that the water temperature in the second heating outlet pipe 140 cannot meet the use requirement of the user within the preset time, the gas heating is used, and the state of heating by electricity is closed.
With continued reference to fig. 1, when the user selects the bathroom mode, the mode has three states of pure electric heating, gas heating or dual-energy heating (i.e., an operation mode of simultaneously using electric heating and gas heating). When pure electric heating is used, the heating pipe 214 in the electric water heater 210 is electrified for heating, the third water pump 530 operates, and the flow direction of the bathroom water is as follows: bathroom return 250- & gt auxiliary heat exchanger 310- & gt first bathroom inlet pipe 220- & gt electric water heater 210- & gt bathroom outlet pipe 230- & gt bathroom return 250. When heating is performed using gas, the first switching device 410 is in the first state, the first switching port 411 and the second switching port 412 are in communication, the second switching device 420 is in the fourth state, and the fourth switching port 421 and the fifth switching port 422 are in communication. The outlet of the first heating outlet pipe 130 is communicated with the inlet of the first water inlet end 311 of the auxiliary heat exchanger 310, and the inlet of the first heating return pipe 120 is communicated with the outlet of the first water outlet end 312 of the auxiliary heat exchanger 310. The main heat exchanger 110, the first heating outlet pipe 130, the auxiliary heat exchanger 310, and the first heating return pipe 120 constitute a circulation loop, and the bathroom system 200 can use heat generated by the heating system 100 by means of the auxiliary heat exchanger 310. The flow direction of the bathroom water is bathroom return pipe 250, auxiliary heat exchanger 310, first bathroom inlet pipe 220, electric water heater 210, bathroom outlet pipe 230, bathroom return pipe 250, and the flow direction of the heating water is: the main heat exchanger 110- & gt the first heating outlet pipe 130- & gt the auxiliary heat exchanger 310- & gt the first heating return pipe 120- & gt the main heat exchanger 110. When the dual energy source heating is used, the flow directions of the heating water and the bathroom water are consistent with those of the heating water and the bathroom water which are heated by using only the fuel gas, the states of the water pumps and the switching devices are consistent with those of the heating water and the switching devices which are heated by using only the fuel gas, meanwhile, the heating pipe 214 in the electric water heater 210 is electrified for heating, and the third water pump 530 operates.
It should be noted that, in the bathroom mode, the temperature of the water in the first bathroom water inlet pipe 220 may be detected by the third temperature detecting unit 630, the temperature of the water in the second bathroom water inlet pipe 240 may be detected by the fourth temperature detecting unit 640, and the temperature of the water in the water storage tank 211 may be detected by the temperature measuring pipe 213, and if the temperature of the bathroom water is detected within the preset time, it is indicated that the use requirement of the user cannot be satisfied by only using the gas heating, and at this time, the dual-energy heating may be used.
With continued reference to fig. 1, when the user selects the heating-bathroom mode, since the gas heating and the electric heating are in different systems, the heating system 100 adopts gas heating, the bathroom system 200 adopts electric heating, and the two systems can operate independently without affecting each other. In this way, when the heating system 100 and the bathroom system 200 in the related art share the gas heating, the water temperatures in the two systems are mutually affected, and the heat generated by the bathroom and the heating cannot be effectively utilized.
Referring to fig. 1, when the user selects the zero cold water mode, if the temperature of the water in the first bathroom water inlet pipe 220 is detected by the third temperature detecting unit 630 or the temperature of the water in the electric water heater 210 is detected by the temperature measuring pipe 213 to be lower than the user set temperature, the third water pump 530 is operated to heat the bathroom system 200, so that the water temperature of the bathroom water in the bathroom system 200 is maintained within a certain temperature range, and the bathroom water is heated immediately. At this time, the heating manner of the bathroom water in the bathroom system 200 may refer to the content in some embodiments described above, and will not be described herein.
In summary, in the embodiment of the present application, by using the electric energy heat source in the bathroom system 200, the heating system 100 and the bathroom system 200 respectively have independent heating sources, so that the synchronous operation function of the heating and the bathroom can be realized. Because the heating system 100 and the bathroom system 200 can exchange heat through the auxiliary heat exchanger 310, by arranging each switching device and each water pump to be matched with each pipeline in the heating system 100 and the bathroom system 200, heat generated during running any one of the heating system 100 and the bathroom system 200 can be utilized by the other system (for example, the bathroom system 200 can utilize the auxiliary heat exchanger 310 to reversely heat heating water), and heat waste is avoided. Meanwhile, the bathroom return pipe 250 is arranged in the pipeline in an auxiliary mode, so that the zero cold water function can be realized. Therefore, the embodiment of the application can realize peak-staggering electricity consumption, heating and heat preservation electricity consumption and reduce emission.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the application. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
