Detailed Description
In order that the application may be readily understood, a more complete description of the application will be rendered by reference to the appended drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling a wall-hanging stove includes steps S500, S600 and S700.
Step S500, when the wall-mounted furnace normally operates, the water outlet temperature of the heating water conveyed to each room by the wall-mounted furnace and the indoor temperature of each room are respectively obtained.
Specifically, the wall-mounted boiler obtains heating water after heating the input cold water, outputs the heating water to different rooms, and heats the rooms by radiating heat in the heating water. The wall-mounted boiler provided by the application comprises a water heating device, a heating water conveying device and a room heating device. The water heating device can heat cold water by natural gas and the like, obtain hot water with a certain temperature and then convey the hot water to the heating water conveying device. The heating water conveying device conveys the hot water to different rooms respectively, and meanwhile, the temperature of the heating water which is finally conveyed to each room is independently controlled according to the outlet water temperature and the indoor temperature of the heating water which are corresponding to different rooms. The room heating device is used for radiating the heat of the heating water conveyed to each room into the room to realize the heating function, and collecting the indoor temperature of each room and feeding back to the heating water conveying device for analysis.
In the technical scheme of the application, the normal operation of the wall-mounted boiler means that the water heating device is positioned in a state that heating water meeting a certain temperature condition can be conveyed to the heating water conveying device. For example, in one more detailed embodiment, it may refer to the water heating device being in heating water in which a difference between a temperature of heating water supplied to the heating water supply device and a preset temperature is less than a second preset temperature difference threshold, wherein the preset temperature is set by a user. After the wall-mounted boiler is in a normal running state, the heating water conveying device starts to execute the wall-mounted boiler control scheme, and firstly, the outlet water temperature of the heating water and the indoor temperature of each room are obtained.
It can be understood that the outlet temperature of the heating water according to this embodiment refers to: after the heating water obtained by heating by the water heating device is split by the heating water conveying device, the water temperatures at the front ends (namely, the ends close to the water heating device) of the conveying pipelines corresponding to different rooms are respectively calculated. The collected water outlet temperatures are basically consistent among different rooms, but the lengths of the conveying pipelines among different rooms are inconsistent, so that the actual water temperatures flowing into the room heating devices are different to some extent, and finally, the indoor temperatures are different.
It should be noted that the way of obtaining the outlet water temperature of the heating water is not the only way, in one embodiment, the outlet water temperature may be collected by temperature detectors separately disposed on each conveying pipeline and then sent to the heating water conveying device, that is, the heating water conveying device in this embodiment does not have a temperature collecting function, and the outlet water temperature is collected by additional temperature detectors. In another embodiment, a plurality of temperature detectors may be integrated in the heating water delivery device, and each temperature detector correspondingly collects a high water temperature in a delivery pipeline, so that the heating water delivery device is utilized to directly obtain the corresponding water outlet temperature of each room. The indoor temperature can be that the room heating devices arranged in all rooms are integrated with temperature detectors, and the indoor temperature is directly collected by the room heating devices in all rooms and then sent to the heating water conveying device.
And S600, comparing and analyzing according to the outlet water temperature and the indoor temperature.
Specifically, after the heating water delivery device obtains the outlet water temperature of the heating water delivered to each room and the indoor temperature of each room, the outlet water temperature and the indoor temperature are combined for comparison analysis. In the comparison and analysis process, the water outlet temperature and the indoor temperature in the same room are respectively compared and analyzed, whether the difference between the water outlet temperature and the indoor temperature in the same room is too large is judged by comparing the difference between the water outlet temperature and the indoor temperature, and the corresponding temperature control is carried out on the room according to the comparison result.
And step S700, heating the heating water conveyed to the current room when the difference value between the outlet water temperature corresponding to the same room and the indoor temperature is larger than or equal to a first preset temperature difference threshold value, and stopping heating until the difference value between the outlet water temperature corresponding to the current room and the indoor temperature is smaller than the first preset temperature difference threshold value.
Specifically, in the solution of this embodiment, a first preset temperature difference threshold is pre-stored in the heating water delivery device, and when the heating water delivery device analyzes the outlet water temperature and the indoor temperature corresponding to each room, the heating water delivery device compares and analyzes the difference between the outlet water temperature and the indoor temperature of the same room and the first preset temperature difference threshold. If the difference value is greater than or equal to the first preset temperature difference threshold value, the fact that the temperature difference is too large is indicated, and the heating water conveyed to the room needs to be heated for the second time, so that the temperature of the actual heating water finally conveyed to the room is increased, and after heat dissipation and heating are finally carried out, the indoor temperature of the room is increased. Because the secondary heating of the heating water is carried out at the rear end of the part for detecting the outlet water temperature, the detected outlet water temperature is basically kept unchanged at the moment, the indoor temperature is increased, the difference between the outlet water temperature and the indoor temperature is gradually reduced finally, and the secondary heating operation of the heating water is stopped after the difference is finally smaller than the first preset temperature difference threshold value.
It should be noted that in the scheme of the present application, the operation of the heating water delivery device to obtain the outlet water temperature and the indoor temperature of each room is performed in real time. Even after the secondary heating is stopped when the difference value between the outlet water temperature corresponding to the current room and the indoor temperature is smaller than the first preset temperature difference threshold value, if the difference value between the outlet water temperature of the room and the indoor temperature is detected to be larger than or equal to the first preset temperature difference threshold value again, the secondary heating of the heating water is started again.
Referring to fig. 2, in one embodiment, after step S600, the method further includes step S800.
Step S800, when the difference between the corresponding outlet water temperature and the indoor temperature in the same room is smaller than the first preset temperature difference threshold, directly conveying the heating water with the current outlet water temperature to the corresponding room.
Specifically, when the heating water conveying device compares and analyzes the outlet water temperature and the indoor temperature corresponding to each room, the situation that the difference between the outlet water temperature and the indoor temperature is smaller than the first preset temperature difference threshold value in some rooms can also occur, and at the moment, the fact that the temperature difference between the outlet water temperature and the indoor temperature of the type of rooms is smaller is indicated, and at the moment, secondary heating of heating water is not needed, and only the heating water corresponding to the current outlet water temperature is directly conveyed to the corresponding room for heating.
Through the scheme of the embodiment, the heating water with larger difference between the outlet temperature and the indoor temperature is conveyed to the corresponding room after being secondarily heated, and the heating water with smaller difference between the outlet temperature and the indoor temperature is directly conveyed to the corresponding room without being secondarily heated. So that the actual water temperature difference of the heating water finally delivered to different rooms can be effectively reduced.
Referring to fig. 3, in an embodiment, before step S500, the method further includes step S100, step S200, and step S300.
Step S100, when a heating signal is received, controlling the wall-mounted furnace to be started for heating water; step S200, obtaining the heating water temperature at the heating water outlet of the wall-mounted furnace; step S300, when the difference value between the heating water temperature and the preset temperature is smaller than a second preset temperature difference threshold value, the state information that the wall-mounted furnace is in normal operation is obtained.
Specifically, the heating signal is a starting signal sent by a user when the user needs to heat by using the wall-mounted furnace. It will be appreciated that the transmission of the heating signal is not exclusive and in one embodiment the heating signal may be transmitted by the user through the room heating appliance and then received by the heating water delivery device. In another embodiment, the user may also directly input in the heating water delivery device.
The wall-hanging stove is opened and is carried out water heating, namely the water heating device of wall-hanging stove starts the operation, and water heating device's specific structure is not unique, in an embodiment, water heating device includes air inlet line, gas proportional valve, water inlet line, combustion component, heating water outlet line and heating water temperature detector, air inlet line, water inlet line and heating water outlet line connect combustion component respectively, gas proportional valve sets up in air inlet line, heating water temperature detector sets up in heating water outlet line, gas proportional valve, heating water temperature detector and combustion component connect heating water conveyor respectively.
When the water heating device starts to operate, water to be heated (cold water or heating water flowing back by the room heating device) flows into the combustion assembly through the water inlet pipeline, meanwhile, fuel gas enters the combustion assembly through the air inlet pipeline, the heating water conveying device controls the combustion assembly to start to operate, fuel gas combusts in the combustion assembly to perform heat exchange, the water to be heated is heated to obtain heating water, and finally, the heating water flows out from the heating water outlet pipeline to the heating water conveying device. In the process, a heating water temperature detector arranged in a heating water outlet pipeline detects which heating water temperature is selected in real time, and the acquired heating water temperature is sent to a heating water conveying device to be compared and analyzed with a preset temperature. If the difference between the heating water temperature and the preset temperature is smaller than the second preset temperature difference threshold, the fact that the heating water obtained by the water heating device meets the user requirement is indicated, and the heating water conveying device considers that the wall-mounted boiler is in a normal running state.
With continued reference to fig. 3, in one embodiment, step S400 is further included after step S200.
Step S400, when the difference between the heating water temperature and the preset temperature is greater than or equal to a second preset temperature difference threshold, the combustion state of the wall-mounted furnace is adjusted until the difference between the heating water temperature and the preset temperature is smaller than the second preset temperature difference threshold.
Specifically, when the heating water transporting device performs comparative analysis according to the heating water temperature and the preset temperature, a case may also occur in which the difference between the heating water temperature and the preset temperature is greater than or equal to a second preset temperature difference threshold. At this time, it is explained that the heating water obtained by the water heating device does not reach the user's expectation, and the combustion state of the wall-hanging stove, specifically, the combustion state of the combustion assembly of the water heating device, will need to be adjusted, so that the temperature of the heating water output from the combustion assembly is increased.
It can be appreciated that the manner of adjusting the combustion state of the wall-mounted boiler is not unique, in a more detailed embodiment, the adjustment of the amount of the fuel gas in the combustion assembly can be achieved, specifically, the opening of the fuel gas proportional valve on the air inlet pipe is increased, so that the fuel gas in the combustion assembly is increased, and the heating water conveying device with higher temperature is obtained through heating, and finally, the difference between the heating water temperature and the preset temperature is smaller than the second preset temperature difference threshold.
Referring to fig. 4, in one embodiment, step S100 includes step S110.
Step S110, when a heating signal is received, a preset temperature is set according to the heating signal, and the wall hanging stove is controlled to be started for heating water.
Specifically, in the solution of this embodiment, the heating signal is not only used for controlling the opening of the wall-mounted boiler, but also for performing the setting operation of the preset temperature in the wall-mounted boiler. That is, in this embodiment, whenever a user needs to perform heating, the preset temperature expected by the user is sent to the heating water delivery device while the wall-hanging stove is started, so that the heating water delivery device controls the heating water with the output temperature matched with the water heating device (that is, the heating water with the temperature difference smaller than the second preset temperature difference threshold value).
According to the wall-mounted boiler control method, during normal operation of the wall-mounted boiler, when heating water is conveyed to each room for heating, the outlet water temperature and the indoor temperature of the heating water corresponding to each room can be obtained simultaneously for comparison and analysis. When the difference between the water outlet temperature and the indoor temperature of a certain room is greater than or equal to a first preset temperature difference threshold, heating water conveyed to the room can be heated for the second time, so that the indoor temperature of the room is increased, the difference between the indoor temperature and the water outlet temperature is reduced, and the difference between the water outlet temperature and the indoor temperature corresponding to the current room is smaller than the first preset temperature difference. Through the scheme, the outlet water temperature of each room can be independently controlled, and when the difference between the outlet water temperature and the indoor temperature is large, the heating water can be heated for the second time to increase the indoor temperature, so that the difference between the outlet water temperature and the indoor temperature is reduced. By performing temperature compensation on the heating water with a larger difference between the outlet water temperature and the indoor temperature, the difference between the actual temperatures of the heating water finally flowing into each room can be reduced, and the indoor temperature difference of each room is further reduced.
Referring to fig. 5, a wall-hanging stove control device includes: a temperature acquisition module 400, a temperature analysis module 500, and a temperature adjustment module 600.
The temperature obtaining module 400 is configured to obtain, when the wall-mounted boiler is operating normally, the outlet water temperature of the heating water delivered to each room by the wall-mounted boiler and the indoor temperature of each room; the temperature analysis module 500 is used for comparing and analyzing according to the outlet water temperature and the indoor temperature; the temperature adjustment module 600 is configured to heat the heating water delivered to the current room when the difference between the outlet water temperature corresponding to the same room and the indoor temperature is greater than or equal to a first preset temperature difference threshold, and stop heating until the difference between the outlet water temperature corresponding to the current room and the indoor temperature is less than the first preset temperature difference threshold.
In one embodiment, the temperature adjustment module 600 is further configured to directly send the heating water with the current outlet water temperature to the corresponding room when the difference between the outlet water temperature and the indoor temperature corresponding to the same room is less than the first preset temperature difference threshold.
Referring to fig. 6, in one embodiment, before the temperature obtaining module 400, the wall-hanging stove control device further includes a start control module 100, a heating water temperature obtaining module 200, and a water heating control module 300.
The starting control module 100 is used for controlling the wall hanging stove to be started for heating water when receiving a heating signal; the heating water temperature acquisition module 200 is used for acquiring the heating water temperature at the heating water outlet of the wall-mounted furnace; the water heating control module 300 is configured to obtain state information that the wall-mounted boiler is in normal operation when a difference between the heating water temperature and the preset temperature is smaller than a second preset temperature difference threshold.
In one embodiment, the water heating control module 300 is further configured to adjust the combustion state of the wall-hanging stove when the difference between the heating water temperature and the preset temperature is greater than or equal to the second preset temperature difference threshold value, until the difference between the heating water temperature and the preset temperature is less than the second preset temperature difference threshold value.
In one embodiment, the start control module 100 is further configured to set a preset temperature according to the heating signal when the heating signal is received, and control the wall hanging stove to be turned on for heating water.
The specific limitation of the wall-mounted boiler control device can be referred to the limitation of the wall-mounted boiler control method, and the description thereof is omitted here. All or part of the modules in the wall-mounted boiler control device can be realized by software, hardware and a combination thereof. The above modules may be embedded in hardware or may be independent of a processor in the computer device, or may be stored in software in a memory in the computer device, so that the processor may call and execute operations corresponding to the above modules.
According to the wall-mounted boiler control device, in the normal operation process of the wall-mounted boiler, when heating water is conveyed to each room for heating, the outlet water temperature and the indoor temperature of the heating water corresponding to each room can be obtained simultaneously for comparison and analysis. When the difference between the water outlet temperature and the indoor temperature of a certain room is greater than or equal to a first preset temperature difference threshold, heating water conveyed to the room can be heated for the second time, so that the indoor temperature of the room is increased, the difference between the indoor temperature and the water outlet temperature is reduced, and the difference between the water outlet temperature and the indoor temperature corresponding to the current room is smaller than the first preset temperature difference. Through the scheme, the outlet water temperature of each room can be independently controlled, and when the difference between the outlet water temperature and the indoor temperature is large, the heating water can be heated for the second time to increase the indoor temperature, so that the difference between the outlet water temperature and the indoor temperature is reduced. By performing temperature compensation on the heating water with a larger difference between the outlet water temperature and the indoor temperature, the difference between the actual temperatures of the heating water finally flowing into each room can be reduced, and the indoor temperature difference of each room is further reduced.
Referring to fig. 7, a wall-mounted boiler includes a water heating device 10, a heating water delivery device 20 and a room heating device 30, wherein the heating water delivery device 20 is connected with the water heating device 10, the room heating devices 30 are respectively arranged in each room, and the room heating devices 30 are respectively connected with the heating water delivery device 20; the water heating device 10 is used for heating water to obtain heating water; the room heating device 30 is used for acquiring the indoor temperature of each room and sending the indoor temperature to the heating water delivery device 20; the heating water supply device 20 is used to control the temperature of the heating water supplied to each room according to the above-described wall-hanging boiler control method.
Specifically, the wall-mounted boiler obtains heating water after heating the input cold water, outputs the heating water to different rooms, and heats the rooms by radiating heat in the heating water. The wall-mounted boiler provided by the application comprises three parts, namely a water heating device 10, a heating water conveying device 20 and a room heating device 30. The water heating apparatus 10 may heat cold water by natural gas or the like to obtain hot water having a predetermined temperature, and then deliver the hot water to the heating water delivery apparatus 20. The heating water delivery device 20 delivers the hot water to different rooms, and simultaneously analyzes the outlet water temperature and the indoor temperature of the heating water corresponding to different rooms, thereby realizing independent control of the temperature of the heating water finally delivered to each room. The room heating device 30 is used for radiating the heat of the heating water delivered to each room to the room to realize the heating function, and collecting the indoor temperature of each room and feeding back to the heating water delivery device 20 for analysis.
The outlet temperature of the heating water is as follows: after the heating water heated by the water heating device 10 is split by the heating water conveying device 20, the water temperatures at the front ends of conveying pipelines under different rooms (namely, at the end close to the water heating device 10) respectively correspond to each other. Therefore, the temperature of different rooms can be acquired to obtain the water outlet temperature of heating water.
After the heating water supply device 20 obtains the outlet temperature of the heating water supplied to each room and the indoor temperature of each room, a comparison analysis is performed with respect to each outlet temperature and the indoor temperature. In the comparison and analysis process, the water outlet temperature and the indoor temperature in the same room are respectively compared and analyzed, whether the difference between the water outlet temperature and the indoor temperature in the same room is too large is judged by comparing the difference between the water outlet temperature and the indoor temperature, and the corresponding temperature control is carried out on the room according to the comparison result.
A first preset temperature difference threshold value is pre-stored in the heating water delivery device 20, and when the heating water delivery device 20 respectively analyzes the outlet water temperature and the indoor temperature corresponding to each room, the outlet water temperature and the indoor temperature of the same room are subjected to difference, and then the difference value is compared with the first preset temperature difference threshold value for analysis. If the difference value is greater than or equal to the first preset temperature difference threshold value, the fact that the temperature difference is too large is indicated, and the heating water conveyed to the room needs to be heated for the second time, so that the temperature of the actual heating water finally conveyed to the room is increased, and after heat dissipation and heating are finally carried out, the indoor temperature of the room is increased. Because the secondary heating of the heating water is carried out at the rear end of the part for detecting the outlet water temperature, the detected outlet water temperature is basically kept unchanged at the moment, the indoor temperature is increased, the difference between the outlet water temperature and the indoor temperature is gradually reduced finally, and the secondary heating operation of the heating water is stopped after the difference is finally smaller than the first preset temperature difference threshold value.
When the heating water conveying device 20 performs comparison analysis according to the outlet water temperature and the indoor temperature corresponding to each room, the situation that the difference between the outlet water temperature and the indoor temperature is smaller than the first preset temperature difference threshold value in some rooms also occurs, and this indicates that the temperature difference between the outlet water temperature and the indoor temperature in the same type of room is smaller, and at this time, the heating water is not required to be secondarily heated, and only the heating water corresponding to the current outlet water temperature is required to be directly conveyed to the corresponding room for heating.

When a certain room needs to be heated, the main controller only needs to turn on the water outlet switch 23 on the corresponding conveying pipeline 25 of the room. When the room is heated, the outlet water temperature of the heating water at the front end of the conveying pipeline 25 is detected by the outlet water temperature detector 22 and sent to the main controller for analysis, and if the difference between the outlet water temperature and the indoor temperature of the room is greater than or equal to a first preset temperature difference threshold, the main controller controls the auxiliary heating device 24 to start to operate, and the heating water actually reaching the room is heated for the second time until the difference between the outlet water temperature and the indoor temperature of the room is smaller than the first preset temperature difference threshold.
It is understood that the specific type of the auxiliary heating apparatus 24 is not exclusive, as long as it is capable of performing the secondary heating of the heating water in the different delivery pipes 25, respectively. For example, in one more detailed embodiment, the auxiliary heating 24 is an electrical heating.

Specifically, the room heating device 30 is provided with an indoor temperature detector 33, and the indoor temperature of the corresponding room can be collected and transmitted to the slave controller 32 in real time by the indoor temperature detector 33, and then transmitted to the heating water delivery device 20, specifically, the master controller of the heating water delivery device 20, which is in communication connection with the slave controller 32. The heat radiating fins 34 are provided to the heating pipe 31, and heat generated from heating water in the heating pipe 31 can be transferred to the heat radiating fins 34 and then radiated to the surrounding air through the heat radiating fins 34, thereby realizing a heating operation.

In this process, the heating water temperature detector 16 provided in the heating water outlet pipe 15 detects which heating water temperature you select in real time, and transmits the collected heating water temperature to the heating water delivery device 20 for comparison analysis with a preset temperature. If the difference between the heating water temperature and the preset temperature is smaller than the second preset temperature difference threshold, it indicates that the heating water obtained by the water heating device 10 at this time meets the user requirement, and the heating water conveying device 20 considers that the wall-mounted boiler is in a normal running state.
