Detailed description of the invention: be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings.
First the gas heater according to the utility model first aspect embodiment is specifically described by reference to the accompanying drawings below.
Refer to Fig. 1, Fig. 2, this gas heater mainly comprises heat exchanger 01, water tank 02, water inlet pipe 03, outlet pipe 04, water circulating pump 05, water pump check valve 06, water feeding one-way valve 07, tube connector 08, backwater water inlet pipe 09, water flow sensor 10, inflow temperature probe 11, leaving water temperature probe 12, controller 13.
The water inlet end of described heat exchanger 01 connects water inlet pipe 03, and the water side of heat exchanger 01 connects outlet pipe 04, and water tank 02 is installed in series on outlet pipe 04.In gas heater, so form a heating water route.
Water circulating pump 05 and water pump check valve 06 are installed on water inlet pipe 03, and described water pump check valve 06 can select the upstream extremity or the downstream that are arranged on water circulating pump 05.Water circulating pump 05 is for providing flow dynamic for above-mentioned heating water route, and the installation of water pump check valve 06 is for ensureing water (flow) direction.
Water inlet pipe 04 is also connected with a tube connector 08, this tube connector 08 is arranged in parallel with water circulating pump 05 and water pump check valve 06, particularly, the two ends of tube connector 08 turn on water inlet pipe 04 respectively, the return branch that formation one is in parallel with water circulating pump 05 and water pump check valve 06 on water inlet pipe 04.
Described tube connector 08 is provided with a water feeding one-way valve 07, for ensureing the water (flow) direction in return branch.Described backwater water inlet pipe 09 one end is reserved opening, and the other end is connected with tube connector 08, and backwater water inlet pipe 09 is arranged on the downstream of water feeding one-way valve 07 with the tie point of tube connector 08.
Further, described water inlet pipe 03 is also provided with water flow sensor 10, inflow temperature probe 11, this water flow sensor 10 described, inflow temperature probe 11 are between heat exchanger 01 and tube connector 08 simultaneously, in other words, the water side of tube connector 08 to be connected on water inlet pipe 04 and to form junction, and water flow sensor 10, inflow temperature probe 11 is positioned at the downstream of this junction simultaneously.The setting of water flow sensor 10 is for detecting the water-flow signal in described heating water route, and inflow temperature probe 11 is for detecting the temperature of the water of inflow heat exchanger 01 on water inlet pipe 03.Described outlet pipe 04 is provided with leaving water temperature probe 12, and this leaving water temperature probe 12 is positioned at the downstream of water tank 02, for detecting the water temperature in water pipe 04.
Refer to Fig. 2, described controller 13 is for preset temperature, and this controller 13 and heat exchanger 01, water flow sensor 10, water circulating pump 05, inflow temperature pop one's head in 11, leaving water temperature is popped one's head in 12 is electrically connected.Specifically, described controller 13 for while preset temperature, also for receive water-flow signal that water flow sensor 10 feeds back, for receive and compare the temperature signals of inflow temperature probe 11 and leaving water temperature probe 12 feedback, startup and closedown water circulating pump 05 work, control the combustion conditions of heat exchanger 01.
Just because gas heater in the utility model have employed said structure, make this gas heater under the cooperation of exterior line, water inlet pipe 03, outlet pipe 04 can form a closed-loop path, the water flow in closed-loop path can be allowed to produce water-flow signal by circulating pump 05, thus the water in closed-loop path is heated to the temperature of user's setting by gas water heater working, when treating the first bathing of user, open with water spot, in pipe out be the hot water heated.
The control method of gas heater described in the utility model comprises the following steps:
Step one: the temperature value T3 being set a user's request by controller 13, and an insulation start-up temperature value T4, as T3 being set as 35 C ~ 65 C, and T4 is less than the setting value setting of T3.
Step 2: controller 13 detects the water-flow signal of described water flow sensor 10, if non-water flow signal detected, controller 13 detects the temperature value T2 that coolant-temperature gage probe 12 detects, then then compare the coolant-temperature gage temperature value T2 that detect of probe 12 and temperature value T4, by comparing the running of the temperature difference controlled circulation water pump 05 of T2 and T4.Particularly: if the temperature value of T2 is less than T4, the T4 such as set is 35 C, and the T2 detected is 30 C, hot water water temperature then in outlet pipe does not reach the demand of user, at this moment water circulating pump 05 is started, to drive current, make controller 13 water-flow signal be detected, and enter into following steps 03; If T2 is greater than or equal to T4, the T4 such as set is 35 C, and the T2 detected is 39 C, hot water water temperature then in outlet pipe has reached the demand of user, at this moment water circulating pump 05 does not start, and gets back to above-mentioned steps 02, detects water-flow signal and continues to compare as temperature.
Step 3: after controller 13 detects the water-flow signal of described water flow sensor 10, controller 13 detects the temperature value T2 that coolant-temperature gage probe 12 detects, then compare the temperature value T2 that detect of coolant-temperature gage probe 12 and temperature value T3, by comparing the combustion conditions of the temperature difference adjustment heat exchanger 01 of T2 and T3.Specifically, when the temperature difference of T2 and T3 is larger, the T3 such as set is 42 C, and the T2 detected is 20 C, then strengthen the combusting firepower to heat exchanger 01, when the temperature difference of T2 and T3 is less, the T3 such as set is 42 C, and the T2 detected is 30 C, then reduce the combusting firepower to heat exchanger 01.
Step 4: in heat transfer process, controller 13 detects the temperature value T1 that detect of inflow temperature probe 11, and controller 13 is by comparing T1 and T3, and the running of temperature difference controlled circulation water pump 05 according to T1 and T3.Particularly: if temperature value T1 is less than T3, the T1 such as detected is 40 C, and presetting T3 is 42 C, then the water temperature of water inlet pipe does not reach the demand of user, and get back to step 03, regulate combustion conditions by the temperature difference comparing T1 and T3, heat exchanger 01 continues heat exchange; If T1 is greater than or equal to T3, represent that the water temperature in water inlet pipe has reached the demand of user, then water circulating pump 05 decommissions, and gets back to above-mentioned steps 02, after controller 13 detects non-water flow signal, stops the heating work to heat exchanger 01.
