Background technology
Gas heater is a kind of commonplace household electrical appliance, provides great convenience to people.Most of gas heater employing Hall type water flow sensor carrys out the size of perception discharge, judges the size of current current by the umber of pulse that in the detection unit interval, water flow sensor returns.If there is no for a long time hot water after open water tap, can cause the waste of current, on the contrary, thereby if just detecting current, the too short time opens water heater, when water is closed in the place identical with the water inlet pipe of water heater at other, can impact the water inlet of water heater, thereby cause water heater misoperation.
In addition, existing Hall type water flow sensor generally judges current discharge with following formula: pulse frequency (Hz)=8.1* current sizes (L/min)-3, wherein, pulse frequency is the pulse frequency that Hall type water flow sensor sends according to discharge.For example, discharge per minute is 5L(liter), be 8.1*5-3=37.5Hz according to the frequency of above-mentioned acquisition water flow sensor, that is to say, the signal of discharge is 37.5 pulses of transmission per second.It is generally acknowledged that the discharge that exceedes 3L can start water heater, umber of pulse >=21 per second o'clock are thought and are converted to the time by user's open water tap, think user's open water tap when interval≤47 between two pulses millisecond.The process of carrying out at present discharge detection mainly comprises: detect pulse number in certain hour to judge whether open water tap, for example, when open water tap is thought in pulse number >=10 item in 500ms.Or, detect the interval between two pulses, for example, when being less than 47 milliseconds, the interval between two pulses thinks open water tap.

The gas heater and the control method thereof that propose according to the embodiment of the present invention are described with reference to the accompanying drawings.
Fig. 1 is the flow chart of the control method of gas heater according to an embodiment of the invention.As shown in Figure 1, the control method of the gas heater of the embodiment of the present invention comprises the following steps:
S1, the water inlet water flow signal of detection gas heater.
For example, identical with existing gas heater, can detect water inlet water flow signal by Hall type water flow sensor.Water flow sensor is positioned at the water inlet of gas heater, the current gas heater of flowing through, when there being current to pass through, the magnet rotor of Hall type water flow sensor can rotate, thereby the generation water flow signal corresponding with discharge, in addition, it should be noted that, because laying or the hypertonia of the extraneous connecting pipe of gas heater make water inlet pressure large, also tend to magnet rotor is rotated, thereby water flow sensor detects water flow signal.For example leading apart within 10 meters in kitchen faucet and water feeding of heater, and hydraulic pressure is in 0.2MPa(MPa) when above, kitchen faucet is opened and is closed again, the water flow sensor meeting transmitted of gas heater exceedes the signal of 3L, and the time can reach 600-700 millisecond, be easy to cause maloperation.
S2, judges according to water flow signal whether discharge is more than or equal to default discharge.
Particularly, for example Hall type water flow sensor detects such as pulse signal of water flow signal, its output pulse signal frequency is directly proportional to the rotating speed of magnet rotor, the rotating speed of magnet rotor is directly proportional to discharge again, and then can judge according to water flow signal the relation of discharge and default discharge, if water inlet discharge is more than or equal to default discharge, perform step S3.
S3, if discharge is more than or equal to default discharge, carries out timing, and further judges whether timing time is greater than Preset Time.
If judge discharge be more than or equal to default for example 3L/min of discharge (liter/min), record meets the time of this condition, and by timing time and Preset Time for example 800 milliseconds compare, if timing time is more than or equal to Preset Time, perform step S4.
S4, if timing time is more than or equal to Preset Time, controls gas heater and starts heating.
Particularly, if timing time is more than or equal to Preset Time, speech meets the duration that discharge is more than or equal to default discharge and is more than or equal to for example 800 milliseconds of Preset Times, now think and have current to pass through gas heater, user's tap of fetching boiling water, control gas heater and heat, to ensure, confirming can to heat as early as possible acquisition hot water while really fetching boiling water tap, meeting user's needs.
In one embodiment of the invention, if judgement water inlet discharge is less than default such as 3L/min of discharge, timing zero clearing.Particularly, if when for example water inlet discharge is more than or equal to default discharge, carry out timing, if when the water inlet discharge again detecting is less than default discharge, timing zero clearing, in the time that water inlet discharge is more than or equal to default discharge again, carries out reclocking.
Particularly, in one embodiment of the invention, water flow signal detects by the water flow sensor of gas heater, and then water flow sensor is according to water flow signal production burst frequency signal.As shown in Figure 2, and then comprise the following steps:
S201, obtains the interval time between each pulse according to pulse duration frequency signal.
Wherein, the interval between each pulse and discharge have corresponding relation.
S202, judges whether be less than or equal to preset interval time interval time.
For example judge whether the interval between pulse is less than or equal to 47 milliseconds, and whether corresponding discharge is more than or equal to 3L/min.If be less than or equal to 47 milliseconds of preset interval time interval time, perform step S203, otherwise return to step S201.
S203, if be less than or equal to preset interval time interval time, carries out timing, and further judges whether timing time is greater than Preset Time.
Particularly, judging that two intervals between pulse are less than or equal to preset interval time for example 47 milliseconds time, carry out timing, record meets the duration of above-mentioned condition, and then judges whether the duration be greater than for example 800 milliseconds of Preset Times, if, perform step S4, in the time that timing time is greater than Preset Time, thinks and have current to flow through gas heater, control water heater and heat.Say according to the duration of the interpulse period of water flow sensor and continuous impulse and judged whether that current pass through gas heater, only have while meeting above-mentioned two conditions simultaneously, just think the current gas heater of flowing through, and then the fan starting of control gas heater, heating tube is opened, and prepares to take fire.Otherwise return to step S201.
In addition, carrying out in the process of timing, if be greater than preset interval time the interval time of pulse, think that the water inlet discharge of gas heater is less than default discharge, timing zero clearing, in the time that the assay intervals time is less than preset interval time again, re-starts timing.
According to the control procedure of above-mentioned gas heater, in a specific embodiment of the present invention, as shown in Figure 3, comprising:
S301, is set with current duration T all=0.
S302, detects that the trailing edge of water flow signal interrupts.
S303, calculates Tn interval time (millisecond) between a upper trailing edge.
S304, judges whether to meet Tn≤47 millisecond.
Wherein, preset interval time is 47 milliseconds.If so, perform step S305, otherwise execution step S308.
S305, has the current duration to increase Tall=Tall+Tn.
S306, judges whether to meet Tall >=800 millisecond.
Wherein, Preset Time is 800 milliseconds, if so, performs step S307, otherwise returns goods step S302.
S307, has current through gas heater, and control fuel gas of fuel gas water heater valve cuts out and heats.
S308, has current duration zero clearing Tall=0.
In sum, according to the control method of the gas heater of the embodiment of the present invention, by the detection discharge of intaking, be more than or equal to default discharge in discharge, and the time that meets this condition is while being more than or equal to Preset Time, confirming has current through gas heater, and then control gas heater and heat, thereby can to whether having current to carry out stricter judgement through gas heater, can avoid laying or hydraulic pressure is too high causes gas heater misoperation because of for example external water pipe of the impact of water inlet, and in the time of the real water of user, control gas heater within a short period of time and start heating, convenient.
The gas heater of embodiment is according to a further aspect of the invention described with reference to the accompanying drawings.
Fig. 4 is the schematic diagram of gas heater according to an embodiment of the invention.As shown in Figure 4, the gas heater 100 of the embodiment of the present invention comprises water flow sensor 10, timer 20 and controller 30.Wherein, water flow sensor 10 is for detection of gas heater water inlet water flow signal.Controller 30 judges according to water flow signal whether discharge is more than or equal to default discharge, and in the time that discharge is more than or equal to default discharge, control timer 20 and carry out timing, and further judge whether timing time is greater than Preset Time, and in the time that timing time is more than or equal to Preset Time, controls gas heater 100 and start heating.
Particularly, for example, identical with existing gas heater, can detect water inlet water flow signal by Hall type water flow sensor.Water flow sensor 10 is positioned at the water inlet of gas heater, the current gas heater of flowing through, when water can rotate by the magnet rotor of Hall type water flow sensor, thereby the generation water flow signal corresponding with discharge, in addition, it should be noted that, because laying or the hypertonia of the extraneous connecting pipe of gas heater make water inlet pressure larger, also tend to magnet rotor is rotated, thereby water flow sensor detects water flow signal.For example leading apart within 10 meters in kitchen faucet and water feeding of heater, and hydraulic pressure is in 0.2MPa(MPa) when above, kitchen faucet is opened and is closed again, the water flow sensor meeting transmitted of gas heater exceedes the signal of 3L, and the time can reach 600-700 millisecond, thereby be easy to cause maloperation.
For example pulse signal frequency of Hall type water flow sensor output water flow signal is directly proportional to the rotating speed of magnet rotor, the rotating speed of magnet rotor is directly proportional to discharge again, and then can judge according to water flow signal the relation of discharge and default discharge, if water inlet discharge be more than or equal to default for example 3L/min of discharge (liter/min), controller 30 is controlled timer 20 and is carried out timing, further, in the time that satisfied water inlet discharge is more than or equal to default discharge, timer 20 continues timing, and then controller 30 judges whether timing time is greater than for example 800 milliseconds of Preset Times.If timing time is more than or equal to Preset Time, speech meets the duration that discharge is more than or equal to default discharge and is more than or equal to for example 800 milliseconds of Preset Times, now think and have current to pass through gas heater, user's tap of fetching boiling water, controller 30 is controlled gas heater and is heated, to ensure, confirming can to heat as early as possible acquisition hot water while really fetching boiling water tap, meeting user's needs.
In one embodiment of the invention, if judgement water inlet discharge is less than default such as 3L/min of discharge, controller 30 is controlled timer 20 timing zero clearings.Particularly, if when for example water inlet discharge is more than or equal to default discharge, carry out timing, if when the water inlet discharge again detecting is less than default discharge, timer 20 timing zero clearings, in the time that water inlet discharge is more than or equal to default discharge again, carry out reclocking.
Particularly, in one embodiment of the invention, detected and obtained water flow signal by water flow sensor 10, water flow sensor 10 can be according to water flow signal production burst frequency signal.And then controller 30 can control blower fan, gas valve according to pulse duration frequency signal, thereby start or stop burning.
Particularly, as the schematic diagram of the course of work of Fig. 5 gas heater that is one embodiment of the present of invention.As shown in Figure 5, the pulse signal that water flow sensor 10 sends different frequency according to the variation of discharge size is to for example CPU of controller 30 (Central Processing Unit, central processing unit), and then CPU obtains the interval time between each pulse according to pulse duration frequency signal, and judge whether be less than or equal to preset interval time interval time, wherein, the interval between each pulse and discharge have corresponding relation.For example current is the discharge of 3L, calculates umber of pulse per second for being less than 21.3 according to formula, is calculated to be the corresponding time, i.e. being spaced apart 47 milliseconds and thinking that discharge is now 3L/min between two pulses.In like manner detect that two umber of pulses are spaced apart 16.18 milliseconds and think that current discharge is 8L/min.For example controller 30 judges whether the interval between pulse is less than or equal to for example 47 milliseconds of preset interval time, and whether corresponding discharge is more than or equal to 3L/min.If be less than or equal to 47 milliseconds of preset interval time interval time, controller 30 is controlled timer 20 and is carried out timing, and further judges whether timing time is greater than Preset Time.
In other words, judging that two intervals between pulse are less than or equal to preset interval time for example 47 milliseconds time, timer 20 carries out timing, record meets the duration of above-mentioned condition, and then controller 30 judges whether the duration be greater than for example 800 milliseconds of Preset Times, and then in the time that timing time is greater than Preset Time, thinks and have current to flow through gas heater, controller 30 is controlled blower fan, heating tube and gas valve startup, controls water heater and heats.Say that controller 30 has judged whether that according to the duration of the interpulse period of water flow sensor and continuous impulse current pass through gas heater, only have while meeting above-mentioned two conditions simultaneously, just think the current gas heater of flowing through, and then the fan starting of control gas heater, heating tube is opened, and prepares to take fire.
In addition, carrying out in the process of timing, if be greater than preset interval time the interval time of pulse, think that the water inlet discharge of gas heater is less than default discharge, controller 30 is controlled timer 20 timing zero clearings, in the time that the assay intervals time is less than preset interval time again, re-start timing.
In sum, according to the gas heater of the embodiment of the present invention, detect water inlet discharge by discharge detector, be more than or equal to default discharge in discharge, and the time that meets this condition of timer record is while being more than or equal to Preset Time, confirming has current through gas heater, and then controller control gas heater heats, thereby can to whether having current to carry out stricter judgement through gas heater, can avoid laying or hydraulic pressure is too high causes gas heater misoperation because of for example external water pipe of the impact of water inlet, and in the time of the real water of user, can control gas heater within a short period of time and start heating, convenient.
