The smoke flue split-flowing mouth is connected with the return airway to form a heat exchange channel. Heat can be transmitted to the water tank. An outlet of the heat exchange channel is connected with a smoke-venting pipe. The furnace mouth and the upper combustor are in an exocentric structure. The furnace mouth is formed on one side of the upper combustor. The smoke flue split-flowing mouth is formed on the other side which is far away from the furnace mouth. The hot water furnace has the advantages that flame currents are increased in the upper combustor in the maximum degree and a journey of high temperature smoke from the furnace mouth to the smoke-venting pipe is added so as to prolong the heat exchange time. The heat energy can be taken full advantages of to heat up the water tank so as to improve heat efficiency and reduce heat losses. The smoke-venting temperature of the smoke-venting pipe is effectively reduced. The service life of the smoke-venting pipe is prolonged. The hot water furnace is high in practicality and suitable for popularization.
Description
Technical field
The utility model relates to a kind of catering facility, particularly a kind of water heater.
Background technology
Existing water heater all is that the heating means that adopt are by the water in the thermal-flame heating water tank of fire door, and with install pipeline in water tank as heat-exchange device, the high-temperature flue gas that produces by the pipeline fuel combustion transmits the water in the water tank with heat form heating.Yet the fire door in the existing water heater is not long to the flow process of smoke exhaust pipe, this is so that cause hot flame stream too short with the time that pot contacts delay, and the contact area of the water in heat-exchange device and the water tank is large not, and this is so that the heat loss of burning generation heat is large, and the efficiency of heating surface is low.
Moreover fuel combustion produces the waste heat that can not get in the flue gas effectively utilizing and finally discharges from smoke exhaust pipe, so that smoke exhaust pipe easily burns out, greatly reduce its service life.
The utility model content
The purpose of this utility model is to provide the water heater that a kind of heat loss is little, the thermal efficiency is high, by prolonging to greatest extent the holdup time of hot flame stream in upper combustion chamber, overcome the deficiency that traditional water heater thermal efficiency is not high and heat loss is low, thereby realized the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of water heater comprises a body of heater, and the inside of body of heater is provided with burner hearth, upper combustion chamber and water tank, and upper combustion chamber is connected with burner hearth by fire door, and upper combustion chamber is provided with a flue diffluence pass, is provided with an air-return duct in the water tank; The flue diffluence pass is connected with air-return duct and forms hot switching path, with the heat transferred water tank, the outlet of this hot switching path also links to each other with smoke exhaust pipe, flue gas is discharged, fire door and upper combustion chamber are eccentric structure, fire door is located at a side of upper combustion chamber, and the flue diffluence pass is located at the opposite side away from fire door.
Preferably, flue diffluence pass and air-return duct form at least two-way hot switching path.
It is to be noted especially, hot switching path is arranged on around the outer wall of upper combustion chamber ringwise.
Preferably, flue diffluence pass and smoke exhaust pipe lay respectively at the two ends of upper combustion chamber.
Preferably, burner hearth is provided with the first air channel, is provided with the second air channel for the secondary air distribution in the upper combustion chamber.
The beneficial effects of the utility model are:
Farthest increased flame and flowed in upper combustion chamber and the stroke of high-temperature flue gas from the fire door to the smoke exhaust pipe, prolonged heat exchanger time, taken full advantage of heat energy water tank is heated, improved the thermal efficiency and reduced thermal losses; Effectively reduce the exhaust gas temperature of smoke exhaust pipe, prolonged the service life of smoke exhaust pipe, practical, be suitable for promoting.
Description of drawings
Fig. 1 be water heater described in the utility model side view.
Fig. 2 is that water heater shown in Figure 1 is along the structure chart of A-A line.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
As shown in Figure 1, water heater described in the utility model comprises body of heater 100, is arranged on burner hearth 110, upper combustion chamber 130, smoke exhaust pipe 220 and water tank 200 in the body of heater 100, burner hearth 110 tops are provided with fire door 120, upper combustion chamber 130 is arranged on body of heater 100 tops, and link to each other with burner hearth 110 by fire door 120, and fire door 120 and upper combustion chamber 130 are set for the eccentric;
The air channel 240 that is used for ventilating is arranged on burner hearth 110 belows and is communicated with burner hearth 110;
Air-return duct 210 is arranged in the form of a ring around upper combustion chamber's 130 outer walls and is arranged in the water tank 200, with the water tank 200 common hot switching paths that form, also is provided with the second air channel 250 for the secondary air distribution on the air-return duct 210, so that with full combustion of fuel;
Be connected by a flue diffluence pass 220 between upper combustion chamber 130 and the air-return duct 210, its position is arranged on by fire door 120 sides far away, to prolong the stroke of flame stream in upper combustion chamber 130 as far as possible;
On air-return duct 210, be provided with the smoke exhaust pipe 220 that leads to body of heater 100 outsides with flue diffluence pass 220 other sides corresponding, upper combustion chamber 130;
During equipment work, after the fuel process burning of burner hearth 110, flame stream is emerged from fire door 120, in upper combustion chamber 130 through completing combustion behind the 250 secondary air distributions of the second air channel, the formation high-temperature flue gas enters air-return duct 210 from the flue diffluence pass 220 of upper combustion chamber's 130 opposite sides, and be two strands of high-temperature flue gas at flue diffluence pass 220 place's bidirectional shunts, in air-return duct 210, carry out heat exchange with water tank 200, finally discharge from the smoke exhaust pipe 220 of the other end; Since fire door 120 in upper combustion chamber 130 eccentric setting so that the flame stream time of staying in upper combustion chamber 130 longer, add the secondary air distribution in the second air channel 250, to greatest extent with full combustion of fuel, produce more heat, avoided simultaneously the waste of fuel and imperfect combustion and the pernicious gas that produces;
Moreover, because flue diffluence pass 220 is enough large apart from smoke exhaust pipe 220 distances, the high-temperature flue gas that fuel combustion produces is enough large in the distance of air-return duct 210 interior motions, be arranged between air-return duct 210 and the water tank 200 in the water tank 200 and can carry out heat exchange for more time, water in the more heat transferred water tank 200 is arranged, waste heat also can well be utilized, so that water can be heated sooner; Because the cigarette temperature that smoke exhaust pipe 220 is discharged reduces, and has also prolonged the service life of smoke exhaust pipe 220.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
