Below with reference to accompanying drawing, introduce in detail according to water heater of the present utility model.
As depicted in figs. 1 and 2, according to water heater of the present utility model, comprising: gas heating unit 100, electric heating unit 200, hot water outlet pipe 300, switch unit 400, check valve 500 and controller 600.
Specifically, gas heating unit 100 comprises cooling water inlet 101 and hot water outlet 102.
Electric heating unit 200 comprises water inlet 201 and delivery port 202.
(as shown in Figure 1 hot water outlet pipe 300 upper end) is connected switch unit 400, the water inlet 201 of electric heating unit 200 and hot water outlet pipe's 300 input with the hot water outlet 102 of gas heating unit 100 respectively.Advantageously, switch unit 400 can be the transfer valve such as three two-way valves.Further, described three two-way valves can be magnetic valve.
The delivery port 202 of electric heating unit 200 is connected with hot water outlet pipe 300.Check valve 500 is located between the delivery port 202 and hot water outlet pipe 300 of electric heating unit 200.
Controller 600 is connected with gas heating unit 100, electric heating unit 200 and switch unit 400 respectively.
More specifically, as depicted in figs. 1 and 2, according to an example of the present utility model, gas heating unit 100 comprises: burner 103 and heat exchanger tube 104.
In burner 103, be limited with combustion chamber 1031 and be positioned at combustion chamber 1031 Heat Room 1032 above.Burner 103 has the air inlet 105 being communicated with combustion chamber 1031 and the exhaust outlet 106 being communicated with heat exchanger 1032.
At least a portion of heat exchanger tube 104 is wrapped on the periphery wall of Heat Room 1032.Wherein, the lower end of heat exchanger tube 104 is that the upper end of cooling water inlet 101 and heat exchanger tube 104 is hot water outlet 102.
Advantageously, heat exchanger tube 104 is copper pipe.
As depicted in figs. 1 and 2, according to an example of the present utility model, electric heating unit 200 comprises: inner bag 203 and heater 204.
In inner bag 203, being limited with water storage cavity 2031 and water inlet 201 and delivery port 202 is formed on inner bag 203.Heater 204 is located in inner bag 203.
Advantageously, electric heating unit 200 also comprises heat-insulation layer 205.The periphery wall of heat-insulation layer 205 coated inner bags 203.
According to water heater of the present utility model, when independent use gas heating unit, controller is controlled switch unit makes the hot water outlet of gas heating unit be communicated with and close the water inlet of electric heating unit with hot water outlet pipe, now, the hot water through the heating of gas heating unit flows directly into hot water outlet pipe for user through hot water outlet.When independent use electric heating unit, controller is controlled the heat exchanging part of gas heating unit and is not worked, and controller is controlled switch unit makes the hot water outlet of gas heating unit and the water inlet of electric heating unit be communicated with and close hot water outlet pipe's input, and cold water flows into hot water outlet pipe for user by delivery port through check valve after electric heating unit heating.When using combustion gas-electric Hybrid Heating, controller is controlled switch unit makes the hot water outlet of gas heating unit and the water inlet of electric heating unit be communicated with and close hot water outlet pipe's input, cold water enters electric heating unit by hot water outlet through water inlet and continues heating after the preheating of gas heating unit, and hot water flows into hot water outlet pipe for user by the delivery port of electric heating unit through check valve.Simple in structure, easy to use.
Specifically, when adopting combustion gas-electric Hybrid Heating pattern, controller is controlled gas heating unit 100 and is first started, now cold water enters gas heating unit 100 through the cooling water inlet 101 of heat exchanger tube 104, meanwhile, combustion gas is entered the interior burning in combustion chamber 1031 of burner 103 by air inlet 105, and the heat of generation is delivered to Heat Room 1032, cold water carries out heat exchange by the part heat exchanger tube 104 being wrapped on Heat Room 1032 outer walls, and the waste gas that burning produces is discharged by exhaust outlet 106.Now, controller 400 is controlled switch unit 400 makes hot water outlet 102 and water inlet 201 be communicated with and close hot water outlet pipe 300 input, so that flow out gas heating unit 100 by hot water outlet 102 and flow in the inner bag 203 of electric heating unit 200 through water inlet 201 through the water of preheating, by heater 204, continue heating.When the water in inner bag 203 is heated to preference temperature, it is interior for user that hot water flows into hot water outlet pipe 300 by delivery port 203 through check valve 500.Adopt combustion gas-electric Hybrid Heating pattern, can avoid shortcoming that gas heating mode heat exchange efficiency is low, simultaneously, water after preheating, can avoid that Electric heating heating power is large, the high shortcoming of loading.
When occurring having a power failure, wait in the time of cannot using electric heating unit 200, controller 600 controls switch unit 400 and hot water outlet 102 is communicated with hot water outlet pipe 300 and cuts out water inlet 201.Now cold water enters gas heating unit 100 through the cooling water inlet 101 of heat exchanger tube 104, simultaneously, combustion gas is entered the interior burning in combustion chamber 1031 of burner 103 by air inlet 105, the heat producing is delivered to Heat Room 1032, cold water carries out heat exchange by the part heat exchanger tube 104 being wrapped on Heat Room 1032 outer walls, and the waste gas that burning produces is discharged by exhaust outlet 106.Water through heating is interior for user by hot water outlet 102 outflow gas heating unit 100 inflow hot water outlet pipes 300.Owing to being provided with check valve 500 between delivery port 202 and hot water outlet pipe 300, now can prevent that hot water from flowing in inner bag 203.
In the time of cannot using gas heating unit 100 when occurring stopping the supple of gas or steam etc., the heat exchanging part (being burner 103) that controller 600 is controlled gas heating unit 100 is not worked, and controller 600 control switch units 400 make hot water outlet 102 and water inlet 201 be communicated with and close hot water outlet pipe 300 input.Cold water is entered in inner bag 203 by cooling water inlet 101-heat exchanger tube 104-hot water outlet 102-switch unit 400-water inlet 201, by heater 204, is heated.Water in inner bag 203 is heated to after preference temperature, and hot water is flow in hot water outlet pipe 300 for user through check valve 500 by delivery port 202.
According to water heater of the present utility model, can guarantee at any time to have hot water to use, there is more economical energy-conservation mode of heating, can improve the efficiency of heating surface and firing rate.Cold water is after preheating, and heating power is little, it is low to load; Have gas heating and electrically heated function concurrently, water heater overall volume is little, the stand-by period is short; Water temperature stability; When the fortuitous event such as occur having a power failure or stop the supple of gas or steam, allow to ensure hot water use; Cost is lower, simple in structure.
