Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, a heating stove control method is provided, the heating stove can be an electric heating stove, a fuel oil heating stove, a fuel gas heating stove and the like, and water heated by the heating stove can be used for life heating and can also be used for users to drink. For the sake of understanding, the following explanation will be given by taking a gas heating stove as an example. As shown in fig. 1, the heating stove control method includes:
step S110: whether temperature sensing devices arranged at different positions of the heating furnace break down or not is detected.
Specifically, the temperature sensing devices arranged at different positions of the heating furnace can be subjected to fault detection through the control device. The control device can be an original main control board of the heating stove or an independent controller. The temperature sensing device is connected with the control device, whether the temperature sensing device breaks down or not is detected, and the subsequent operation of controlling the water outlet by combining the temperature signal which is not collected when the temperature sensing device breaks down is carried out.
The specific type of the temperature sensing device is not exclusive and can be a temperature sensing bulb or a temperature sensor, in this embodiment, the temperature sensing device adopts the temperature sensing bulb, the temperature sensing bulb can be fixed on the water pipe and used for sensing the water temperature in the water pipe, and temperature information is converted into a temperature sensing signal and is uploaded to the control device. The temperature sensing device is not unique in the arrangement mode of the heating stove, and can be arranged at a water outlet and/or a water return port of the heating stove.
The control device can detect the fault of the temperature sensing device when the heating stove is started, or can start working according to the normal operation program of the temperature sensing device after the heating stove is started, and simultaneously detect whether the temperature sensing device has the fault. The mode of detecting whether the temperature sensing device is in failure by the control device is not unique, and the control device can communicate with each temperature sensing device to detect the state of the temperature sensing device so as to judge whether the temperature sensing device is in failure; or recording the time of receiving the temperature sensing signal uploaded by the temperature sensing device, and if a new sensing signal is not received after a certain time after the sensing signal is received for the last time, determining that the temperature sensing device fails and cannot transmit the signal.
In one embodiment, step S110 includes: if the temperature sensing signal sent by the temperature sensing device is not received after the preset time, the corresponding temperature sensing device fails. The specific value of the preset duration is not unique and can be set according to the actual situation. The control device records the time of each temperature sensing device sending the temperature sensing signal, and if the temperature sensing device does not send the temperature sensing signal for more than the preset time, the temperature sensing device can be considered to be in fault, and the detection is simple, convenient and quick.
Step S120: and calling a corresponding preset program according to the temperature sensing device without the fault.
Specifically, the control device may pre-store a plurality of different operation programs, and each operation program may normally operate when the corresponding temperature sensing device has no fault. After determining which temperature sensing devices are in fault, the control device calls a preset program corresponding to the temperature sensing devices capable of working normally to be used for water outlet control of the heating stove subsequently. Taking the example that the temperature sensing device comprises a water outlet temperature sensing bulb and a water return temperature sensing bulb, the control device can pre-store three operation programs: program a, program b, and program c. The program a controls water outlet according to temperature sensing signals detected by the water outlet temperature sensing bulb and the water return temperature sensing bulb, the program b controls water outlet according to the temperature sensing signals detected by the water return temperature sensing bulb, and the program c controls water outlet according to the temperature sensing signals detected by the water outlet temperature sensing bulb. If the water outlet temperature sensing bulb and the water return temperature sensing bulb are not in fault, calling the program a; if the water outlet temperature sensing bulb fails and the water return temperature sensing bulb does not fail, calling the program b; and if the return water temperature sensing bulb fails and the water outlet temperature sensing bulb does not fail, calling the program c.
Step S130: and receiving a temperature sensing signal sent by the temperature sensing device without faults, and controlling the water outlet of the heating stove according to the temperature sensing signal and a called preset program.
And after the control device determines the temperature sensing device without faults and calls the corresponding preset program, the control device controls the water outlet of the heating stove according to the temperature sensing device without faults and the called program so as to ensure the normal operation of the heating stove. For example, if the water outlet temperature sensing bulb fails, the return water temperature sensing bulb does not fail, and the program b is adopted to control according to the sensing signals collected by the return water temperature sensing bulb; and if the backwater temperature sensing bulb fails and the water outlet temperature sensing bulb does not fail, controlling by adopting a program c according to the sensing signal acquired by the water outlet temperature sensing.
According to the heating stove control method, whether the temperature sensing devices arranged at different positions of the heating stove break down or not is detected, the corresponding preset program is called according to the temperature sensing devices which do not break down, the water outlet control is carried out on the heating stove according to the temperature sensing signals sent by the temperature sensing devices which do not break down by using the called preset program, the normal operation of the heating stove can be still ensured when part of the temperature sensing devices break down, professional maintenance personnel are not required to be informed at once, and the use reliability of the heating stove is improved.
In one embodiment, the temperature sensing device comprises a water outlet temperature sensing bulb and a water return temperature sensing bulb, the water outlet temperature sensing bulb is arranged at a water outlet of the heating stove, and the water return temperature sensing bulb is arranged at a water return port of the heating stove. Water after the heating stove heating is exported circulating pipe through the delivery port, and the heat dissipation flows in circulating pipe for the life heating, and the water after the cooling flows back by the return water mouth of heating stove among the last circulating pipe to supply the heating stove to heat once more. Through set up out water temperature sensing package and return water temperature sensing package respectively at the delivery port of heating stove and return water mouth, controlling means carries out the temperature regulation according to the temperature-sensing signal who gathers at the delivery port of heating stove and return water mouth.
In one embodiment, the heating furnace is embodied as a gas heating furnace. As shown in fig. 2, step S130 includes step S131 and step S132.
Step S131: and if the water outlet temperature sensing bulb and the water return temperature sensing bulb are not in fault, receiving temperature sensing signals sent by the water outlet temperature sensing bulb and the water return temperature sensing bulb.
Step S132: and controlling the water outlet of the heating stove according to the temperature sensing signals sent by the water outlet temperature sensing bulb and the water return temperature sensing bulb and the called preset program.
Similarly, taking the example that the preset program comprises a program a, a program b and a program c, if it is detected that neither the water outlet temperature sensing bulb nor the water return temperature sensing bulb has a fault, the control device controls the water temperature by using the program a according to the temperature sensing signals sent by the water outlet temperature sensing bulb and the water return temperature sensing bulb. Specifically, the control device detects the temperature by using the water outlet temperature sensing bulb and the water return temperature sensing bulb simultaneously, and increases the combustion power of the heating stove when the difference between the water outlet temperature and the water return temperature is large (for example, the difference is larger than a set threshold) and the water outlet temperature does not reach the temperature set by a user. When the difference between the outlet water temperature and the return water temperature is small (for example, the difference is less than or equal to a set threshold), and the outlet water temperature reaches the temperature meeting the user setting, the combustion power of the heating stove is correspondingly reduced. Meanwhile, the water temperature is adjusted by using the temperature sensed by the water outlet temperature sensing bulb and the return water temperature sensing bulb, so that the combustion can be optimized, the comfort is improved, and the fuel gas is saved.
Further, in one embodiment, step S132 includes: calculating to obtain a difference value between the outlet water temperature and the return water temperature according to temperature sensing signals sent by the outlet water temperature sensing bulb and the return water temperature sensing bulb; and correspondingly adjusting the combustion power of the heating furnace according to the difference value of the water outlet temperature and the water return temperature and the called preset program.
Specifically, the control device calls the program a to control the water temperature, when the water outlet temperature does not reach the temperature set by the user, the control device calculates the difference between the water temperature and the return water temperature according to temperature sensing signals sent by the water outlet temperature sensing bulb and the return water temperature sensing bulb, and correspondingly changes the opening of a fuel gas proportional valve of the heating stove and/or the air supply quantity of a fan according to the difference so as to adjust the combustion power of the heating stove. When the difference value between the water outlet temperature and the water return temperature is larger than a set threshold value, the larger the difference value is, the larger the adjustment range of the combustion power of the heating stove is. Taking the adjustment of the opening of the gas proportional valve of the heating furnace as an example, assuming that the set threshold is 10 ℃, if the difference value between the outlet water temperature and the return water temperature is 11-20 ℃, controlling the opening of the gas proportional valve of the heating furnace to increase by 1 ℃, and increasing the combustion power of the heating furnace; if the difference value of the outlet water temperature and the return water temperature is 21-30 ℃, controlling the opening of a gas proportional valve of the heating stove to increase by 2 ℃, and so on, changing the opening of the gas proportional valve of the heating stove according to the actual situation of the difference value of the outlet water temperature and the return water temperature, quickly reducing the temperature difference between the outlet water temperature and the return water temperature, and improving the outlet water temperature to reach the temperature set by a user. It can be understood that if the difference between the outlet water temperature and the return water temperature is less than 10 ℃, and the outlet water temperature reaches the outlet water temperature, the opening degree of the fuel gas proportional valve can be reduced, so that the combustion power of the heating stove is reduced.
In one embodiment, step S130 further includes step S133 and step S134.
Step S133: and if the backwater temperature sensing bulb has no fault, receiving a temperature sensing signal sent by the backwater temperature sensing bulb.
Step S134: and controlling the water outlet of the heating stove according to the temperature sensing signal sent by the return water temperature sensing bulb and the called preset program.
And if the water outlet temperature sensing bulb is detected to be in fault and the return water temperature sensing bulb is normal, the control device adopts the program b to control the water temperature according to the temperature sensing signal sent by the return water temperature sensing bulb. Specifically, the control device calculates the theoretical return water temperature by combining the heat loss of the heating furnace in the heating process according to the outlet water temperature set by the user. If the heating pipeline and the equipment structure are not changed, the heat loss in the heating process can be considered to be kept unchanged, and the control device can directly deduce and calculate the current theoretical return water temperature by combining the outlet water temperature set by a user through a set algorithm in a program. The control device compares the actual return water temperature with the theoretical return water temperature, and adjusts the combustion power according to the comparison result to ensure that the combustion power is in a normal range and avoid abnormal temperature rise.
In one embodiment, with continued reference to fig. 2, step S130 further includes step S135 and step S136.
Step S135: and if the water outlet temperature sensing bulb has no fault, receiving a temperature sensing signal sent by the water outlet temperature sensing bulb.
Step S136: and controlling the water outlet of the heating stove according to the temperature sensing signal sent by the water outlet temperature sensing bulb and the called preset program.
And if the backwater temperature sensing bulb is detected to be in fault and the water outlet temperature sensing bulb is normal, the control device adopts a program c to control the water temperature according to a temperature sensing signal sent by the water outlet temperature sensing bulb. Specifically, the control device determines the actual outlet water temperature according to the temperature sensing signal sent by the outlet water temperature sensing bulb, compares the actual outlet water temperature with the outlet water temperature set by the user, and adjusts the combustion power according to the size relationship between the actual outlet water temperature and the outlet water temperature set by the user, so that the combustion power is ensured to be in a normal range, and abnormal temperature rise is avoided.
In one embodiment, as shown in fig. 3, after step S110, the method further includes step S140.
Step S140: and if the temperature sensing device fails, outputting corresponding failure reminding information according to the failed temperature sensing device. Step S140 may be performed after step S120, or may be performed after the corresponding program is called to run in step S130. According to different fault temperature sensing devices, the specific content of the output fault reminding information is different, so that a user is informed of the fault temperature sensing device, and maintenance personnel are informed to maintain.
The mode of outputting the fault reminding information is not unique, and can be through voice broadcast, also can utilize the display screen to display information such as corresponding characters, pictures and the like, and also can adopt more than two output modes to combine to carry out fault reminding. In addition, when the fault problem of the temperature sensing device is solved through maintenance, the control device detects that the temperature sensing device is normal, and then the program a is switched to operate again.
It should be understood that although the various steps in the flow charts of fig. 1-3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.

In one embodiment, there is also provided a heating stove system comprising a heating stove and the heating stove control apparatus described above. Wherein, the heating stove is specifically gas heating stove, including gas proportional valve, fan etc. controlling means passes through the gas proportional valve and controls the gas admission volume in the gas pipeline to and the intake of getting into the heating stove through fan control. And water in the circulating pipeline flows back to the heating furnace through a water return port of the heating furnace, the fuel gas mixed air burns to heat the water flowing back from the water return port, and the heated hot water flows out of the circulating pipeline through a water outlet.
Above-mentioned heating stove system is through detecting whether the temperature sensing device that sets up at the heating stove different positions breaks down to according to the temperature sensing device that does not break down and calling the corresponding procedure of predetermineeing, the temperature-sensing signal that the temperature sensing device that utilizes the predetermined procedure of calling sent according to not breaking down carries out the water control to the heating stove, still can guarantee the heating stove normal operating when some temperature sensing device breaks down, need not to inform professional maintenance personnel at once and also can continue to use, has improved the use reliability of heating stove.
In order to better understand the above heating stove control method, apparatus and heating stove system, the following detailed explanation is made in conjunction with specific embodiments.
In case of water temperature detection failure of the traditional gas heating water heater, the whole machine cannot operate, and professional maintenance personnel need to be informed to maintain so as to continue to use the water heater. In winter, once the whole machine breaks down, maintenance personnel cannot be in place immediately, so that the user experience is poor, and the whole machine is possibly frozen due to cold to break down.
Based on this, the heating stove control scheme that this application provided, go out water department and return water at gas heating water heater and go out all to install a temperature sensing package, but two temperature sensing packages simultaneous use and mutual independence. When the two temperature sensing bags are used simultaneously, the temperature of outlet water and the temperature of return water can be detected, and the combustion power is determined by comparing the temperature difference between the outlet water and the return water. When the control device detects that one of the water outlet temperature sensing bulb and the water return temperature sensing bulb has a fault, the control device automatically operates another program algorithm to ensure the operation of the whole machine and prompts which temperature sensing bulb has the fault. The problems of shutdown and poor user experience caused by temperature sensing bulb faults are effectively solved; and simultaneously, the combustion performance can be more optimized.
The heating stove control principle is as shown in fig. 4, three programs are recorded in advance on the program of the main control board: program a, program b, program c.
When the whole machine normally operates, the whole machine operates according to a default program a, and the temperature of the water outlet temperature sensing bulb and the temperature of the water return temperature sensing bulb are detected simultaneously. When the difference between the outlet water temperature and the return water temperature is large and the outlet water temperature does not reach the temperature set by the user, the combustion power is correspondingly increased. When the difference value between the outlet water temperature and the return water temperature is small and the outlet water temperature basically reaches the temperature set by the user, the combustion power is correspondingly reduced, so that the combustion can be optimized, the comfort is improved, and the fuel gas is saved. The main control board can adjust the combustion power by changing the opening of the fuel gas proportional valve and the air output of the fan. Meanwhile, the main control board monitors the time for the temperature sensing bulb to send the temperature sensing signal, and if the temperature sensing signal is not received after the preset time, the corresponding temperature sensing bulb is considered to be abnormal.
When the whole machine normally operates according to the default program a, the main control board detects that the water outlet temperature sensing bulb is abnormal, and when the water return temperature sensing bulb is normal, the program is automatically switched to the preset program b in the control board. And the whole machine operates according to a preset program in the program b, and calculates the current theoretical return water temperature by using an algorithm set in the program according to the water outlet temperature value set by a user. The actual return water temperature is compared with the theoretical return water temperature, and the combustion power is adjusted according to the comparison result, so that the problem that the shutdown is caused due to the fault of the return water temperature sensing bulb is avoided, and the user experience is poor. Meanwhile, a display panel of the heating stove displays the fault of the water temperature sensing bulb, and prompts a user to inform professional maintenance personnel to maintain. And after the maintenance is finished by the maintenance personnel, the fault is cancelled, and the whole machine is automatically switched to the program a to operate. And the program b takes the detected temperature of the backwater temperature sensing bulb as a main algorithm to ensure that the combustion power is in a normal range and avoid abnormal temperature rise.
When the whole machine normally operates according to the default program a, the main control board detects that the backwater temperature sensing bulb is abnormal and the water outlet temperature sensing bulb is normal, the program is automatically switched to the preset program c in the control board. The whole machine runs according to a preset program in the program c, the combustion power is adjusted according to the size relation by comparing the outlet water temperature with the outlet water temperature value set by a user, and the phenomenon that the machine is shut down due to the fault of the outlet water temperature sensing bulb is avoided, so that the user can experience relatively badly. And meanwhile, the fault of the backwater temperature sensing bulb is displayed on a display panel of the heating furnace, and a user is prompted to inform a professional maintenance worker to maintain. And after the maintenance is finished by the maintenance personnel, the fault is cancelled, and the whole machine is automatically switched to the program a to operate. And the program c takes the detected temperature of the water outlet temperature sensing bulb as a main algorithm to ensure that the combustion power is in a normal range and avoid abnormal temperature rise.
