[0045] The integrated water circuit module of the utility model can not only supply the water to be heated to the heat exchanger through the first water outlet 220 to supply hot water, but also can divert and output domestic water or softened domestic water through the second water outlet 230 to supply unheated water to the outside, so that the integrated water circuit module has the function of outputting both hot and cold water and has better integration, which is beneficial to improving the functional expansion potential of the hot water device equipped with the integrated water circuit module, so as to better meet the user's needs for the use of hot and cold water.

[0055] Furthermore, the valve member 300 is disposed on the second channel 202 between the water inlet 210 and the second water outlet 230. By disposing the valve member 300 on the second channel 202 and between the water inlet 210 and the second water outlet 230, the water output in the second water outlet 230 can be adjusted by the valve member 300, with better control accuracy.

[0061] Designers can adjust the specific structure of the tee 203 and its location on the integrated component 200 according to usage requirements, and no specific restrictions are made here.

[0062] Implementation Method 2

[0063] Please refer to Figure 4 As shown, a gas water heater is provided in an embodiment of the utility model, which includes a shell 600, the integrated water circuit module described in embodiment one, a second heat exchanger 400 and a burner for heating the second heat exchanger 400; the inlet of the first flow channel 110 is connected to the water outlet of the second heat exchanger 400, and the outlet of the first flow channel 110 is connected to the water inlet 210 of the second heat exchanger 400; the outlet of the second flow channel 120 is used to supply heated water to the outside.

[0064] The specific structure, working principle and beneficial effects of the integrated water channel module are the same as those described in the first embodiment and will not be repeated here.

[0065] By using the integrated water circuit module described in Example 1, the gas water heater can not only supply water to be heated to the heat exchanger through the first water outlet 220 to supply hot water, but also divert domestic water or softened domestic water through the second water outlet 230 to supply unheated water to the outside.

[0066] The utility model provides the integrated water circuit module on the gas water heater, so that the gas water heater has the function of outputting both hot and cold water, has better integration, and is beneficial to improving the functional expansion potential of the gas water heater, so as to better meet the user's needs for hot and cold water.

[0067] In addition, the burner can heat the second heat exchanger 400 to generate a heating medium, so that when the inlet of the first flow channel 110 is connected to the water outlet of the second heat exchanger 400, and the outlet of the first flow channel 110 is connected to the water inlet 210 of the second heat exchanger 400, the heating medium can flow from the second heat exchanger 400 into the first flow channel 110, and then the heating medium in the first flow channel 110 can heat the water to be heated flowing in the second flow channel 120, so that the gas water heater has an efficient hot water output capability and can better meet the user's needs for hot water.

[0068] Designers can adjust the specific types of the second heat exchanger 400 and the burner according to usage requirements, and no specific restrictions are made here.

[0069] In order to improve the structural stability, in the embodiment of the utility model, a support frame 620 connected to the housing 600 is also included. By connecting the valve member 300 in the integrated waterway module to the support frame 620, the structural stability of the valve member 300 is significantly improved, which also helps to reduce the vibration generated by the valve member 300 during use, thereby reducing the generation of vibration noise. In addition, the part of the integrated component 200 formed with the second channel 202 can also be set on the support frame 620, which is conducive to improving the stability of the second channel 202 during use.

[0072] By arranging the functional water generation module 500 on the gas water heater, the functional water generation module 500 can be used to process the water body, thereby meeting subsequent use needs.

[0073] Furthermore, by connecting the outlet of the functional water generating module 500 with the water inlet 210 of the integrated component 200, the water treated by the functional water generating module 500 can enter the integrated component 200, and then the treated water can be diverted to the first channel 201 and / or the second channel 202 through the integrated component 200.

[0074] When the treated water is diverted to the first channel 201, the treated water can flow along the first channel 201 to the first water outlet 220, and enter the second flow channel 120 from the first water outlet 220, so that the treated water can exchange heat with the heating medium in the first flow channel 110 in the second flow channel 120 to produce hot water, and finally the hot water can be output along the outlet of the second flow channel 120, thereby meeting the user's demand for thermal functional water or hot water.

[0075] When the treated water is diverted to the second channel 202, the treated water can flow along the second channel 202 to the second water outlet 230, and enter the external water use equipment 900 from the second water outlet 230, thereby playing the role of supplying functional water, and this part of the treated water has not been heated, so as to better meet the user's needs for the use of cold functional water.

[0076] In actual use, the above two states can be performed separately to output hot water or cold functional water respectively, or can be performed simultaneously to output hot water and cold functional water at the same time, which has better flexibility of use.
