[0037] The first interface 123 and the third interface 25 are connected by a connecting pipe 3. The cold water plate heat exchanger inlet 22 is connected to the warm water plate heat exchanger outlet 15, and the hot water plate heat exchanger inlet 14 is connected to the hot water plate heat exchanger outlet 23.

[0038] When using water for bathroom purposes, cold water (room temperature water) enters the inlet valve 2 through the cold water inlet 21. A portion of the cold water flows from the cold water plate heat exchanger inlet 22 into the heat exchanger 001, where it undergoes heat exchange to warm up and become warm water. This warm water flows from the warm water plate heat exchanger outlet 15 into the outlet valve, then through the second mounting chamber 121 and out of the bathroom outlet 132 for bathroom use. Another portion of the cold water entering the inlet valve 2 enters the cold water chamber 122 through the connecting pipe 3 from the first interface 123. When the bathroom outlet 13... 2. When the temperature of the outflowing warm water is too high, the cold water chamber 122 is connected to the second installation chamber 121 through the mixing valve 5. The cold water in the cold water chamber 122 enters the second installation chamber 121 and mixes with the warm water inside, thereby reducing the temperature of the warm water. The cooled warm water then flows out from the bathroom outlet 132. Through the above design, the temperature of the bathroom water outlet can be regulated, which not only greatly improves the temperature regulation of the bathroom water outlet and extends the service life of the wall-hung boiler, but also reduces energy consumption and has a good energy-saving effect.

[0039] When using water in the bathroom, the circulating hot water heated in the wall-hung boiler enters the first installation chamber 112 from the hot water inlet 113, and then enters the plate heat exchanger 001 from the hot water plate heat exchanger inlet 14. It exchanges heat with the cold water entering the plate heat exchanger 001 from the inlet valve 2. The cooled hot water flows into the inlet valve 2 from the hot water plate heat exchanger outlet 23, and then flows into the water pump (not shown in the figure) from the water pump interface 24. The water pump then transports the cooled hot water to the boiler of the wall-hung boiler for heating.

[0041] like Figure 5As shown, the shell 1 comprises a water mixing unit 13, the water mixing unit 13 comprises a water mixing cavity 131, the upper end of the water mixing cavity 131 is covered with a first plug 7, the second mounting cavity 121, the water mixing cavity 131 and the bathroom water outlet 132 are communicated, the inside of the water mixing unit 13 is provided with a partition 133, the two sides of the partition 133 are provided with a first water mixing channel 134 and a second water mixing channel 135, the first water mixing channel 134 is communicated with the second mounting cavity 121 through a first liquid passing channel 17, the hot water plate outlet 15, the second mounting cavity 121, the first liquid passing channel 17, the first water mixing channel 134, the second water mixing channel 135 and the bathroom water outlet 132 form a water path of the bathroom water outlet 132, the side of the first water mixing channel 134 close to the bottom is communicated with the first liquid passing channel 17, the upper part of the first water mixing channel 134 is communicated with the upper part of the second water mixing channel 135, and the lower part of the second water mixing channel 135 is communicated with the bathroom water outlet 132.

[0042] When the hot water and the cold water are mixed in the second mounting cavity 121, the mixed water passes through the first liquid passing channel 17, the first water mixing channel 134 and the second water mixing channel 135 in sequence and finally flows out from the bathroom water outlet 132, by arranging the first liquid passing channel 17, the first water mixing channel 134 and the second water mixing channel 135, the water mixing distance can be lengthened under the premise of ensuring that the water mixing unit 13 has a low position, so that the uniformity of the mixing of the cold water and the hot water is greatly improved, which is beneficial to the control of the water temperature of the bathroom water outlet and improves the user experience.

[0044] The cross-sectional areas of the first liquid passing channel 17, the first water mixing channel 134 and the second water mixing channel 135 are the same, by the above design, the liquid passing resistance of the mixed water can be effectively reduced, and the bathroom water outlet effect is improved.

[0045] As shown in Figure 6 The second interface 136 is provided on the side of the water mixing unit 13, and a temperature sensor 6 is mounted at the end of the second interface 136. The sensing end of the temperature sensor 6 is inserted into the second water mixing channel 135 and is close to the bathroom water outlet 132. The temperature sensor 6 is arranged close to the bathroom water outlet 132, so that the temperature of the water at the bathroom water outlet 132 can be detected, and the detection accuracy of the temperature is improved.

[0048] As shown in Figure 12 The water mixing valve 5 in the prior art is mounted above the water mixing unit 13, and forms the outline shown by the dashed line a. As can be seen, in the wall-hanging stove shell 002, the plate heat exchanger 001 cannot be directly disassembled. By front-mounting the water mixing valve 5, the height of the right side of the three-way valve 4 can be effectively reduced, so as to form a avoiding space, so that the plate heat exchanger 001 can be directly removed from the front, which greatly facilitates the installation and maintenance of the plate heat exchanger 001. The connecting pipe 3 is arranged on the front of the water outlet valve and the water inlet valve 2, which not only facilitates the installation of the connecting pipe 3, but also enables the connecting pipe 3 to be away from the plate heat exchanger 001, thereby greatly reducing the heat conduction from the plate heat exchanger 001 to the connecting pipe 3. Furthermore, by front-mounting the water mixing valve 5, the distance between the connecting pipe 3 and the plate heat exchanger 001 can be further increased, so that the connecting pipe 3 can be more away from the plate heat exchanger 001.

[0051] By integrally forming the tee unit 11, the valve seat 12, the water mixing unit 13 and the bypass unit 18, the assembly of the outlet valve can be greatly facilitated, and the production efficiency of the outlet valve can be improved.

[0052] Since the water mixing water path structure is arranged in the outlet valve, the bypass valve 8 is arranged on the side of the tee unit 11 away from the water mixing unit 13, which can ensure that there is enough gap between the inlet valve 2 and the outlet valve, which not only facilitates the installation of other accessories in the wall-hanging stove, but also does not affect the disassembly of the plate heat exchanger 001.
