Description
Technical field
The present invention relates to a kind of gas heater manufacture, particularly to a kind of temperature sensing based on constant temp gas water heater
Device active redundancy(-ce) method.
Background technology
Intelligent constant-temperature combustion gas fast type water heater (hereinafter referred to as Thermostatic water heaters) and intelligent constant-temperature burnt gas wall hanging furnace (with
Lower abbreviation wall-hung boiler, when providing domestic hot-water's function at this mainly for wall-hung boiler, same afterwards) in, it is used for detecting, entering coolant-temperature gage
Temperature (detection) sensor, be a kind of particularly important parts.Because Thermostatic water heaters and wall-hung boiler can carry out homoiothermic
Temperature control, accurately controls leaving water temperature, all relies on the detection to water temperature of temperature (detection) sensor, so working as temperature
During (detection) sensor experiences failure, existing solution is water heater and wall-hung boiler starts work the most normally, enters
Failsafe state, and the code of displays temperature (detection) sensor fault, remind user to report for repairment.So, water heater and
Wall-hung boiler will be unable to use, it is impossible to provide a user with hot water (particularly cold weather when, and after-sales service again can not and
Time follow-up situation), can give user hot water for life bring great inconvenience, Thermostatic water heaters in this case and wall hanging
Stove might as well be common for user forced-ventilated or Flue Gas Water Heater there is advantage.
Summary of the invention
For this situation, in order to solve in the case of at water heater only temperature sensor fault, miscellaneous part is normal,
Traditional intelligent constant-temperature inoperable problem of combustion gas fast type water heater, in the case of ensureing safety, it is provided that a kind of based on
The temperature sensor active redundancy(-ce) method of constant temp gas water heater, specifically includes:
(1) water heater detection module detects whether temperature sensor breaks down in real time, in this way, enters step (2)；
(2) determine whether leaving water temperature sensors fault, in this way, enter step (3)；
(3) ignoring the leaving water temperature sensors detecting function of fault, water heater enters forced-ventilated water heater mode of operation, this mould
In formula, user can be adjusted by firepower setting module, arrange firepower value heats water, firepower value and water temperature one_to_one corresponding, as " the
42 grades of firepower values " corresponding 42 degree of hot water, can there is the error in positive and negative several years in actual hot water, for ensureing that user uses safety, to fire
Power setting value range of accommodation is defined, and preferably firepower value set point is between 35 48, and i.e. corresponding hot water temperature is 35
Between 48 degree, there is the error in positive and negative several years in hot water temperature corresponding to actual firepower value.
Further, in step (2), also comprise the steps of:
If (2-1), leaving water temperature sensors is normal, then judge inflow temperature sensor whether fault, in this way, enter and walk
Suddenly (2-2-1)；As no, water heater returns normal mode of operation.
(2-2-1) ignoring the inflow temperature sensor detecting function of fault, water heater enters single leaving water temperature sensors work
Operation mode: the water outlet temperature setting that leaving water temperature sensors during water heater initial start is sensed by water heater main control module is for entering
Coolant-temperature gage, water heater carries out initial heating according to this inflow temperature to water.
In other embodiment, step (2) comprises the steps of:
If (2-1), leaving water temperature sensors is normal, then judge inflow temperature sensor whether fault, in this way, enter and walk
Suddenly (2-2-2)；As no, water heater returns normal mode of operation.
(2-2-2) water heater enters inflow temperature and sets mode of operation: in this pattern, and water heater main control module uses acquiescence
Presetting inflow temperature, water heater carries out initial heating according to this inflow temperature to water, or,
Being set inflow temperature by user in values by inflow temperature setting module, water heater sets according to user
Fixed inflow temperature carries out initial heating to water.Setting mode of operation at inflow temperature, water heater acquiescence is preset inflow temperature and is
20 degree, time the coldest, user can be set regulation to inflow temperature, for user security, by inflow temperature setting value
Scope is defined to 0 30 degree.Setting mode of operation at inflow temperature, water heater will ignore the spy of the inflow temperature sensor of fault
Brake, and according to the inflow temperature set, water is heated.
Further, step (3) also comprises the steps of
(3-1) water heater enters after forced-ventilated water heater mode of operation, determines whether inflow temperature sensor whether fault,
Enter step (3-2) in this way, as no, perform forced-ventilated water heater mode of operation.
(3-2) ignoring the inflow temperature sensor detecting function of fault, water heater enters inflow temperature and sets forced-ventilated hot water
Device mode of operation: in this pattern, water heater main control module uses acquiescence to preset inflow temperature, and water heater is according to this inflow temperature pair
Water carries out initial heating, or,
Being set inflow temperature by user in values by inflow temperature setting module, water heater sets according to user
