Detailed Description
The invention will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1, a wall-hanging stove according to an embodiment of the present invention includes: the first heat exchanger 10, the first heat exchanger 10 includes a first heat exchange channel and a second heat exchange channel; the second heat exchanger 11, the second heat exchanger 11 includes a third heat exchange channel and a fourth heat exchange channel; the water inlet pipeline 13 is connected with a water inlet of a fourth heat exchange channel of the second heat exchanger 11; the water outlet pipeline 15 is connected with the water outlet of the fourth heat exchange channel of the second heat exchanger 11; a first pipe 17 connecting the first heat exchange passage of the first heat exchanger 10 and the third heat exchange passage of the second heat exchanger 11 and forming a circulation loop; and a second pipeline 19 connected in series with the second heat exchange channel, wherein an inlet end of the second pipeline 19 is connected with the water inlet pipeline 13, and an outlet end of the second pipeline 19 is connected with the water outlet pipeline 15. Therefore, in the wall-mounted boiler, the second heat exchange channel is arranged in the first heat exchanger 10 in the wall-mounted boiler, the second pipeline 19 is connected with the second heat exchange channel in series, the inlet end of the second pipeline 19 is connected with the water inlet pipeline 13, the outlet end of the second pipeline 19 is connected with the water outlet pipeline 15, and when the wall-mounted boiler is in operation, hot water in the water outlet pipeline 15 is formed by mixing the water outlet of the second heat exchanger 11 and the water outlet of the second pipeline 19, and as the water outlet of the second pipeline 19 is directly heated by the second heat exchange channel of the first heat exchanger 10, the heating speed is higher than the heating speed of the water outlet of the second heat exchanger 11, so that the heating speed of the whole water outlet pipeline 15 is improved, and the heating time is shortened. On the other hand, after being split by the second pipeline 19, the water quantity flowing through the fourth heat exchange channel of the second heat exchanger 11 is reduced, the temperature of hot water after heat exchange of the second heat exchanger 11 can be increased, the temperature of the mixed water outlet is further increased, the temperature rise time is shortened, and when the water heater is used, the discharge quantity of cold water can be reduced, and water is saved.
The water in the first heat exchange passage and the second heat exchange passage of the first heat exchanger 10 absorbs heat, the water in the third heat exchange passage of the second heat exchange 11 releases heat, and the water in the fourth heat exchange passage of the second heat exchange 11 is heated by the water in the third heat exchange passage.
Specifically, referring to fig. 2 and 3, in the embodiment of the present invention, the first heat exchanger 10 is a copper tube copper fin heat exchanger, and the lower part of the first heat exchanger 10 is correspondingly provided with a burner 331, where the first heat exchanger 10 is arranged in a staggered manner along the flow direction of the flue gas, so as to increase the flue gas disturbance and strengthen the heat exchange.
More specifically, the first heat exchanger 10 includes an upper heat exchanger and a lower heat exchanger, the upper heat exchanger includes a second heat exchange pipe 107 forming a second heat exchange passage and second heat exchange fins cooperating with the second heat exchange pipe 107, and a pipe joint for connecting with the second pipe 19 is provided on the second heat exchange pipe 107. For the second heat exchange pipeline 107 in the upper row of heat exchangers, the second heat exchange pipeline 107 and the second pipeline 19 can be parallel flow paths, so that the flow of water is shortened, quick hot water outlet is realized, and the outlet water temperature of the wall-mounted boiler during starting is improved. The lower heat exchanger comprises a first heat exchange pipeline 105 forming a first heat exchange channel and first heat exchange fins matched with the first heat exchange pipeline 105, and a pipe joint used for being connected with the first heat exchange pipeline 105 is also arranged on the first heat exchange pipeline 105.

For example, when domestic hot water is used, if the water flow suddenly decreases, when the water flow sensor 23 detects that the water flow decreases by 20% within 2s, the water flow regulating valve 21 is closed, cold water does not pass through the second heat exchange channel of the first heat exchanger 10 for primary heat exchange, and all cold water passes through the second heat exchanger 11 for secondary heat exchange, so that the fluctuation of the water flow in the second heat exchanger 11 is reduced, the rising amplitude of the temperature of the water discharged by the secondary heat exchange is reduced, the mixing of primary heat exchange high-temperature water passing through the second pipeline 19 is not achieved, the water discharged temperature of the domestic hot water is relatively stable, the comfort of the domestic hot water is improved, and the potential safety hazard caused by overlarge temperature rise is reduced. When the water flow sensor 23 detects that the water flow rises by 20% within 2s again, the water flow regulating valve 21 is opened again to split the water inlet pipeline 13, so that the reduction range of the outlet water temperature of domestic hot water is reduced, and the comfort is improved.
In another embodiment, the water inlet pipeline 13 and the second pipeline 19 are both provided with water flow sensors 23, or only the second pipeline 19 is provided with the water flow sensors 23, so that sudden drop of water pressure can be detected, the corresponding control water flow regulating valve 21 reduces or cuts off water flow in the second pipeline 19, the temperature of the water outlet is reduced, water temperature control is realized, and excessive temperature rise is avoided to scald users.
As shown in fig. 1, the wall-mounted boiler in the embodiment of the invention further includes a water pump 25 disposed on the first pipeline 17, where the water pump 25 can drive water in a circulation loop formed by the first pipeline 17, the first heat exchange channel in the first heat exchanger 10, and the third heat exchange channel in the second heat exchanger 11 to flow, and by controlling the flow speed of water in the circulation loop, heat exchange can be accelerated, and the outlet water temperature is increased.
