Referring to Fig. 1 to Fig. 4, the zero cooling water wall-mounted boiler comprises a main controller 1, a burner heat exchange device 2, a water inlet pipe 3 and a water outlet pipe 4. A mixing water tank 5 is provided between the burner heat exchange device 2 and the water inlet pipe 3. The mixing water tank 5 has a first water inlet 51, a first water outlet 52, a second water inlet 53 and a second water outlet 54. The first water inlet 51 is connected to the water outlet end of the water inlet pipe 3, the first water outlet 52 is connected to the water inlet end of the burner heat exchange device 2, and the water outlet end of the burner heat exchange device 2 is connected to the second water inlet 53 is connected, the second water outlet 54 is connected to the water inlet end of the water outlet pipe 4, a first water pumping device 61 is provided between the first water inlet 51 and the water inlet pipe 3, a second water pumping device 62 is provided between the second water outlet 54 and the water outlet pipe 4, a third water pumping device 63 is provided between the first water outlet 52 and the burner heat exchange device 2, a water temperature probe 55 is provided in the mixing water tank 5, and the main controller 1 is electrically connected to the first water pumping device 61, the second water pumping device 62, the third water pumping device 63 and the water temperature probe 55 respectively.

As shown in Figure 1, when the wall-mounted boiler is initially started, the main controller 1 first controls the first pumping device 61 and the second pumping device 62 to stand by, and the third pumping device 63 is started, so that the cold water in the pipeline between the mixing tank 5 and the burner heat exchange device 2 can be circulated and heated and quickly heated until the water temperature probe 55 detects that the water temperature reaches the preset value. As shown in Figure 2, the main controller 1 starts the first pumping device 61 and the second pumping device 62 again, so as to supply water to the user end normally.

By setting up the mixing water tank 5, when the wall-mounted boiler is working, the cold water can be circulated and heated before being discharged to the water outlet pipe 4, so as to avoid that some cold water remaining in the pipeline will be directly delivered to the user end, thereby improving the user's comfort and avoiding the waste of water resources. In addition, since the warm water that has not reached the preset temperature will not be directly discharged to the outside but will be circulated and heated, the efficiency of heating the cold water is also improved, which is beneficial to reducing the energy consumption of the whole wall-mounted boiler.

Furthermore, an electric switching valve 7 is also provided between the first water inlet 51 and the water inlet pipe 3, the electric switching valve 7 includes a water inlet mechanism and a water outlet mechanism, the water inlet mechanism includes a water inlet end a, the water outlet mechanism includes a water outlet end b and a water outlet end c, the water inlet end a of the electric switching valve 7 is connected to the water inlet pipe 3, the water outlet end b of the electric switching valve 7 is connected to the first water inlet 51, the water outlet end c of the electric switching valve 7 is also connected to a cold water pipe 71, the electric switching valve 7 is electrically connected to the main controller 1, the electric switching valve 7 forms different conduction states between the water inlet mechanism and the water outlet mechanism through the main controller 1, by setting the electric switching valve 7 and the cold water pipe 71, as shown in Figure 3, the user can obtain the cold water effect when cold water is needed at the use end according to actual use needs (for example, in application scenarios such as washing fruits and vegetables).

When cold water is needed, the main controller 1 controls the electric switching valve 7 to cut off the water inlet a and the water outlet b while connecting the water inlet a and the water outlet c. When the wall-mounted boiler needs to provide warm water to the outside, the main controller 1 controls the electric switching valve 7 to cut off the water inlet a and the water outlet c while connecting the water inlet a and the water outlet b.

Furthermore, the water outlet pipe 4 is connected to a heating pipe 8, which is used to provide heating to the external user end. The water inlet mechanism also includes a water inlet end d. The water inlet end of the heating pipe 8 is connected to the water outlet pipe 4, and the water outlet end of the heating pipe 8 is connected to the water inlet end d of the electric switching valve 7. The warm water in the heating pipe 8 can flow back to the mixing tank 5 through the water inlet end d to form a circulation. At this time, as shown in Figure 4, the main controller 1 controls the electric switching valve 7 to cut off the water inlet end d and the water outlet end c while connecting with the water inlet end d and the water outlet end b, and cut off the water inlet end a from the water outlet ends b and the water outlet end c.

Furthermore, a smoke exhaust pipe 9 is provided above the burner heat exchange device 2, the first water outlet 52 is connected to the burner heat exchange device 2 via a preheating pipe 91, the third water pumping device 63 is arranged on the preheating pipe 91, and the preheating pipe 91 is adjacent to the smoke exhaust pipe 9, so that the preheating pipe 91 can use the waste heat of the smoke exhaust pipe 9 to preheat or keep the internal water warm, thereby reducing the heat discharged to the outside of the wall-mounted boiler and improving the energy efficiency of the whole wall-mounted boiler.

Furthermore, the preheating tube 91 is wound around the inner side of the smoke exhaust pipe 9 , so that the water flow in the preheating tube 91 can better absorb the residual heat in the smoke exhaust pipe 9 .

Furthermore, a water level detection device 56 is provided in the mixing tank 5, and the water level detection device 56 is electrically connected to the main controller 1. The main controller 1 can control the first water pumping device 61 to replenish cold water to the mixing tank 5 according to the feedback of the water level monitoring device to avoid affecting the normal operation of the wall-mounted boiler.

As shown in FIG. 2 , when the water level in the mixing pipe 5 is lower than a preset value, the main controller 1 controls the electromagnetic switching valve 7 to connect the water inlet end a and the water inlet end d to the water outlet end b, and to disconnect the water inlet end a and the water outlet end d from the water outlet end c.

Furthermore, the mixing tank 5 is connected to a stirring mechanism 10, which includes a motor 101 arranged on the outside of the mixing tank 5 and a stirring member 102 connected to the motor 101, and the stirring member 102 extends inward to the inside of the mixing tank 5. When external cold water enters the mixing tank 5, the warm water and cold water in the mixing tank 5 can be quickly mixed by the stirring mechanism 10, thereby avoiding the situation where part of the warm water output to the outside appears as cold water, thereby improving the user experience.
