Specifically, after the tap water enters the bathroom channel through the bathroom water inlet 21, it enters the heat exchanger 10 through the bathroom water outlet 22; at the same time, due to the action of the water pump 40, the heating water flows through the heat exchanger 10, and then enters the heating water through the heating water inlet 24. The water channel 26 enters the water pump 40 from the heating water outlet 25 . In this way, the low-temperature sanitary water and the high-temperature heating water conduct heat exchange in the heat exchanger 10, so as to achieve the purpose of heating the sanitary water.

1 to 4, in an embodiment of the present invention, the wall-hung boiler includes:

heat exchanger 10;

A water inlet valve 20, the water inlet valve 20 is provided with a bathroom water inlet 21, a bathroom water outlet 22, and a bathroom water channel 23 connecting the bathroom water inlet 21 and the bathroom water outlet 22, and the bathroom water outlet 22 is connected to the bathroom water outlet 22. The heat exchanger 10 is in communication;

The flow regulating valve 30 is arranged at any one of the sanitary water inlet 21 , the sanitary water outlet 22 and the sanitary water channel 23 .

It should be noted that the flow regulating valve 30 may be a manual valve, a solenoid valve or a water proportional valve, etc. The present invention does not limit the type of the flow regulating valve 30 . In addition, the flow regulating valve 30 can be installed at the sanitary water inlet 21 , the sanitary water outlet 22 or the sanitary water channel 23 , and the present invention does not limit its specific installation position, as long as the flow control valve 30 can be installed into the heat exchanger 10 from the water inlet valve 20 . The bathroom water flow can be adjusted.

It should also be noted that the existing wall-hung boiler cannot adjust the flow rate of sanitary water entering the heat exchanger. Although the temperature of the bathroom water outlet can be adjusted by controlling the power of the wall-hung boiler. However, the power of the wall-hung boiler is limited to a certain range value. When the maximum power is reached, the temperature of the bathroom water outlet may be lower than the temperature required by the user (such as in cold winter); when the minimum power is reached, the bathroom water outlet temperature may still be Higher than the user's desired temperature (such as during a hot summer day). In order to make the temperature of the bathroom water in winter meet the needs of users, the existing wall-hung boilers often reduce the flow of bathroom water in the heat exchanger by setting a restrictor ring in the bathroom water channel of the water inlet valve, so that in winter The outlet water temperature of the bathroom water is relatively high, but when it is in summer, users often do not need a high bathroom water temperature. At this time, the wall-hung boiler has the problem that the bathroom water temperature is too high.

It can be understood that when the temperature of the heating water in the heat exchanger 10 is constant, the flow rate of the sanitary water in the heat exchanger 10 will affect the outlet temperature of the sanitary water. When there is less bathroom water in the heat exchanger 10, the heating water of the same temperature will increase the temperature of the bathroom water. smaller. Therefore, in winter, the flow rate of the sanitary water entering the heat exchanger 10 can be reduced through the flow regulating valve 30, so that the outlet temperature of the sanitary water can be increased; while in summer, the flow regulating valve 30 can be used to increase the flow rate of the sanitary water entering the heat exchanger 10. The flow rate of the bathroom water can be adjusted to reduce the outlet temperature of the bathroom water.

In this way, the user can switch the water inlet holes of different water inlet areas to communicate with the bathroom water channel 23 regardless of whether the user rotates to the left or right, without the need for the user to memorize and identify. Of course, in this embodiment, the water inlet hole has only two water inlet areas of different sizes, that is, there are only two levels of bathroom water inlet water flow, which can be easily distinguished by the user. In winter, by rotating the handle 31, the second water inlet hole 322 is communicated with the bathroom water channel 23 to reduce the flow rate of the bathroom water entering the heat exchanger 10, so as to increase the temperature of the bathroom outlet water; in summer, switch the first inlet water The hole 321 communicates with the bathroom water channel 23 to increase the flow rate of the bathroom water entering the heat exchanger 10 so as to reduce the outlet temperature of the bathroom water.
