Detailed Description
The present invention is described in further detail below with reference to the attached drawing figures.
As shown in fig. 1, 2 and 8, the wall-mounted furnace with high efficiency comprises a housing assembly 1, a heat exchanger device 2 and a surrounding plate 10, specifically, the surrounding plate 10 comprises a left surrounding plate 101 and a right surrounding plate 102, the housing assembly 1, the left surrounding plate 101 and the right surrounding plate 102 are assembled to form a closed combustion chamber 4, the heat exchanger device 2 is arranged in the combustion chamber 4, the heat exchanger device 2 comprises a burner 3 and a heat absorption pipeline 8 for heating tap water 17, and the heat absorption pipeline 8 is arranged on one side of the burner 3. The left enclosing plate 101 is provided with an air inlet channel 14, the air inlet channel 14 is connected with the combustor 3, air and fuel gas are mixed according to an optimal proportion and then are conveyed to the combustor 3 through the air inlet channel 14 to be ignited, the ignited fuel gas generates a large amount of high-temperature flue gas 16, and the high-temperature flue gas 16 is filled in the combustion chamber 4. Because the heat absorption pipeline 8 is also arranged in the combustion chamber 4, most of the high-temperature flue gas 16 is actively absorbed by the heat absorption pipeline 8, so that the tap water 17 which circularly flows through the heat absorption pipeline 8 can absorb most of the heat of the high-temperature flue gas 16 to play a role of heating the tap water 17, and the high-temperature flue gas 16 which passes through the heat absorption pipeline 8 is changed into low-temperature flue gas which is discharged out of the wall-hanging furnace from the smoke outlet 9. In the present embodiment, in order to further enable the heat of the high-temperature flue gas 16 to be uniformly absorbed by the heat absorption pipeline 8, a flow guide plate 13 for guiding the flow of the high-temperature flue gas 16 is arranged in the combustion chamber 4, the high-temperature flue gas 16 is uniformly absorbed by the heat absorption pipeline 8 along the flow guide plate 13 and heats the tap water 17, and the flow guide plate 13 prolongs the residence time of the high-temperature flue gas 16 in the combustion chamber 4, so as to give the heat absorption pipeline 8 sufficient heat absorption time, see fig. 8. However, because the high-temperature flue gas 16 contacts the housing assembly 1 in the combustion chamber 4, part of the heat of the high-temperature flue gas 16 can be transferred to the housing assembly 1 and transferred to the outside of the housing assembly 1 in a dissipation manner, so that the loss of the high-temperature flue gas 16 is caused, the heat exchange efficiency of the wall-hanging stove is low, the housing assembly 1 can generate heat, and the user can scald the shell assembly 1 by carelessly touching the shell assembly 1 in the using process, so that the danger exists.
In order to solve the technical problem, the shell assembly 1 of the invention is specially designed, so that the lost heat of the high-temperature flue gas 16 can be recycled for the second time, and the heat exchange efficiency of the wall-mounted furnace can be improved. Specifically, as shown in fig. 3, 4, 5, 6, 7 and 9, the housing assembly 1 includes a housing body 11 with an exhaust port 9 and a plurality of partition plates 12 mounted on the housing body 11, and a plurality of support columns 110 uniformly arranged on the housing body 11 for supporting the partition plates 12 are provided to prevent the partition plates 12 from deforming. The partition board 12 comprises a bottom board 120, a shielding board 121 and a notch 122, the bottom board 120 and the surrounding shielding board 121 form a preheating cavity 7 with an upper opening, the preheating cavity 7 is communicated with the preheating cavity 7 through the notch 122, and the preheating cavity 7 is communicated with the shell body 11 to form a water flow channel 5 for preheating the tap water 17, the water flow channel 5 is of an S shape, as shown in the drawings from 4 to 6, so that the time for the tap water 17 to flow through the water flow channel 5 is prolonged, namely, the time for absorbing heat is prolonged, and the tap water 17 can more uniformly and fully absorb the high-temperature flue gas 5 on the shell body 11. In addition, the shell body 1 is further provided with a water inlet 6, a water inlet end 50 of the water flow channel 5 is communicated with the water inlet 6, a water outlet end 51 of the water flow channel 5 is communicated with the heat absorption pipeline 8, and a water outlet 18 is arranged at the tail end of the heat absorption pipeline 8, so that the preheated tap water 17 can be directly conveyed into the heat absorption pipeline 8 for main heating, on one hand, the time required by heating can be reduced, and on the other hand, the heat of the high-temperature flue gas 16 can be fully utilized.
As an improvement, since the temperature of the heat absorption pipeline 8 and the housing body 11 is reduced by the low-temperature tap water 17 which just enters the water flow channel 5 and the heat absorption pipeline 8, and the high-temperature flue gas generated by the combustion of the burner 3 meets the lower-temperature heat absorption pipeline 8 and the housing body 11, the surface generates condensed water, in the present embodiment, the right enclosing plate 102 is provided with a condensed water outlet 15, see fig. 8, and the condensed water is discharged from the condensed water outlet 15, so that the service life of the heat absorption pipeline 8 can be effectively ensured.
When the wall-mounted boiler is used, the water pipe is opened, tap water 17 firstly enters the water flow channel 5 of the wall-mounted boiler from the water inlet 6, the tap water 17 flows to the heat absorption pipeline 8 along the water flow channel 5, high-temperature flue gas 16 generated by combustion of the combustor 3 is respectively absorbed by the water flow channel 5 and the heat absorption pipeline 8, and the tap water 17 can be preliminarily heated by the high-temperature flue gas 16 absorbed by the tap water 17 flowing through the water flow channel 5, so that the aim of preheating the low-temperature tap water 17 is fulfilled; the preheated tap water 17 can absorb most of the heat generated by the high-temperature flue gas 16 when flowing through the heat absorption pipeline 8, so that the temperature of the tap water 17 can be quickly raised, the time required by heating can be shortened, and the heat utilization rate of the high-temperature flue gas 16 can be improved. In addition, high-temperature flue gas 16 generated by combustion of the combustor 3 is absorbed by tap water 17 and then is changed into low-temperature flue gas, and the low-temperature flue gas is discharged from the smoke outlet 9 to form a heating cycle.
In summary, the heat of the high-temperature flue gas 16 generated by the burner 3 is absorbed by the housing body 11 and the tap water 17 flowing through the heat absorption pipeline 8 at the same time, and the heat of the high-temperature flue gas 16 absorbed by the housing body 11 is absorbed by the tap water 17 circulating through the water flow channel 5, which is equivalent to that the flowing tap water 17 is surrounded around the combustion chamber 4, so as to achieve the effects of preheating the tap water 17 and reducing the temperature of the housing body 11, so that the tap water 17 can absorb heat more fully, the heat exchange efficiency of the wall-mounted furnace is improved, and the wall-mounted furnace is more energy-saving and environment-friendly.
