[0047] First, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0048] Secondly, it should be noted that in the description of the embodiments of the present invention, the terms "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0049] In addition, it should be noted that in the description of the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] With the rapid development of science and technology and the improvement of people's living standards, the number and types of household appliances in people's homes are increasing, including washing machines, air conditioners, refrigerators, heating furnaces, etc. In the face of cold weather in winter, users have the need for heating, and household heating furnaces are used. In winter, people can use heating furnaces for heating and heating domestic water.

[0052] The existing gas heating furnace can be used after installation and water filling. During use, when the heating furnace is ignited for heating, the water pump with a mechanical automatic exhaust valve is operated to discharge the bubbles in the pipeline after water filling or during heating. However, since the existing gas heating furnace exhaust method can only operate the water pump for exhaust when ignited for heating, the exhaust is not timely, the water temperature in the pipeline rises too quickly, and then the heating furnace is shut down for protection. After the water temperature drops, the heating furnace restarts, resulting in frequent start and stop of the heating furnace.

[0053] The present embodiment provides a method for exhausting a gas heating furnace. After the user turns on the machine, the heating furnace determines whether it is necessary to execute the exhaust procedure based on the exhaust parameters and the valve opening time. When the exhaust procedure needs to be executed, different exhaust methods are set according to whether the heating furnace is a plate-type heat exchanger or a sleeve-type heat exchanger. If the heating furnace is a plate-type heat exchanger, it is necessary to use a three-way valve and a water pump with a mechanical automatic exhaust valve to exhaust the bubbles in the heating circuit and the hot water circuit. If the heating furnace is a sleeve-type heat exchanger, it is necessary to use a water pump with a mechanical automatic exhaust valve to exhaust the bubbles in the pipeline. After the exhaust procedure is executed, ignition and heating are performed. This solution expels the bubbles in the pipeline before ignition and heating, so that the water temperature in the pipeline can be steadily increased, reducing the operating risk of the heating furnace.

[0054] The principles and features of the embodiments of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the embodiments of the present invention and are not used to limit the scope of the embodiments of the present invention.

[0055] For example, Figure 1 The structure of the gas heating furnace provided by the present invention is schematically shown Figure 1 ,like Figure 1 As shown, the gas heating furnace is a plate heat exchanger, and the gas heating furnace 10 includes: a heat exchanger 11, a three-way valve 12, a heating circuit 13, a hot water circuit 14 and a water pump 15 with a mechanical automatic exhaust valve.

[0056] For example, the following is combined Figure 1 The application scenario of the gas heating furnace exhaust method provided in the embodiment of the present invention is described.

[0057] After the heating furnace 10 is installed and filled with water, the user turns it on. The heating furnace 10 determines whether to execute the exhaust procedure based on the exhaust parameters and development time. When the exhaust procedure needs to be executed, the heating furnace 10 determines that it is a plate exchanger based on the model parameters, and then controls the three-way valve 12 to be adjusted to the first position, so that the heat exchanger 11 is connected to the heating circuit 13, and then controls the water pump 15 to circulate, so that the bubbles in the heating circuit can be discharged. The three-way valve 12 is controlled again to be adjusted to the second position, so that the heat exchanger 11 is connected to the hot water circuit 14, and then the water pump 15 is controlled to rotate. The rotation time reaches the preset fourth time, and then the three-way valve 12 is adjusted to the first position, and the rotation is stopped for the preset third time. In this way, the bubbles in the hot water circuit can be discharged by cyclic operation.

[0058] For example, Figure 2 The structure of the gas heating furnace provided by the present invention is schematically shown Figure 2 ,like Figure 2 As shown, the gas heating furnace is a casing machine, and the gas heating furnace 20 includes: a heat exchanger 21, a heating circuit 22 and a water pump 23 with a mechanical automatic exhaust valve.

[0059] For example, the following is combined Figure 2 The application scenario of the gas heating furnace exhaust method provided in the embodiment of the present invention is described.

[0060] After the heating furnace 20 is installed and filled with water, the user turns it on, and the heating furnace 20 determines whether to execute the exhaust procedure according to the exhaust parameters and the valve opening time. When the exhaust procedure needs to be executed, the heating furnace 20 determines that it is a casing machine according to the model parameters, and then controls the water pump 23 to circulate, so that the bubbles in the pipeline of the heating furnace 20 can be discharged.

[0061] It should be noted that the above example is only a schematic diagram of the structure of the gas heating furnace, and the embodiment of the present invention is not Figure 1 and Figure 2 The actual forms of various devices in the solution are not limited, nor are the interaction methods between devices limited. In the specific application of the solution, it can be set according to actual needs.

[0062] The gas heating furnace provided in this embodiment discharges the bubbles in the pipeline before ignition and heating, so that the water temperature in the pipeline is steadily increased, reducing the operating risk of the heating furnace.

[0063] The technical solution of the present invention is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0064] Figure 3 A schematic diagram of a process flow of a gas heating furnace exhaust method according to an embodiment of the present invention is shown in FIG. Figure 3 As shown, the gas heating furnace exhaust method specifically includes the following steps:

[0065] S301: In response to the user's power-on operation, determine whether to execute the exhaust program according to the exhaust parameters currently stored in the gas heating furnace and the valve opening time of the gas heating furnace.

[0066] After the gas heating furnace is installed and filled with water, the user can turn it on and use it.

[0067] In this step, after the user turns on the gas heating furnace, the heating furnace can directly obtain the exhaust parameters and valve opening time stored in the heating furnace. Therefore, the heating furnace responds to the user's power-on operation and determines whether to execute the exhaust program based on the exhaust parameters currently stored in the gas heating furnace and the valve opening time of the gas heating furnace.

[0068] It should be noted that the user can turn on the heating furnace by pressing a button on the heating furnace or by using a remote control to control the heating furnace to turn on. The embodiment of the present invention does not limit the user's turning on method, and the user can choose according to actual conditions.

[0069] S302: When the exhaust parameter is a first preset value and the valve opening time is less than or equal to a preset first time, execute the exhaust procedure.

[0070] In this step, after the heating furnace obtains the exhaust parameter and the valve opening time, the exhaust procedure is executed when the exhaust parameter is a first preset value and the valve opening time is less than or equal to the preset first time.

[0071] During the exhaust procedure, the water pump with a mechanical automatic exhaust valve circulates to discharge the bubbles in the pipeline. After the exhaust procedure is completed, the heating furnace is ignited for heating.

[0072] It should be noted that the first preset value and the first preset duration are set in the heating furnace by the staff before the heating furnace leaves the factory, and are used to determine whether to execute the exhaust procedure. The first preset value can be 1 or 2. The first preset duration can be 48 hours or 72 hours. The embodiment of the present invention does not specifically limit the first preset value and the first preset duration, and can be determined according to actual conditions.

[0073] Optionally, while the heating furnace is executing the exhaust program, a prompt animation can also be displayed on the heating furnace's graphical user interface to remind the user that exhaust is in progress and how long it will take to complete the exhaust. When the exhaust is completed, the power-on screen is displayed.

[0074] Optionally, during the exhaust procedure of the heating furnace, the exhaust procedure can be forced to exit by long pressing a specific button on the heating furnace, or by pressing buttons on the heating furnace in a specific order. When the heating furnace is produced and tested, this method can be used to speed up the test and improve the test efficiency.

[0075] The exhaust method of the gas heating furnace provided in this embodiment determines whether to execute the exhaust procedure according to the exhaust parameters and the valve opening time after the user turns on the furnace. The exhaust procedure is executed when the exhaust parameters and the valve opening time meet the conditions, and ignites the furnace for heating after the exhaust is completed. Compared with the prior art that runs a water pump for exhaust during ignition and heating, this solution expels bubbles in the pipeline before ignition and heating, effectively reducing the operating risk of the heating furnace, steadily increasing the water temperature in the pipeline, and improving the heating effect.

[0076] Figure 4 The schematic diagram of the process of the second embodiment of the gas heating furnace exhaust method provided by the present invention is as follows: Figure 4 As shown, in this embodiment, the above step S302 can be implemented by the following steps:

[0077] S401: According to the model parameters of the heating furnace, determine whether the gas heating furnace is a plate-exchanger or a casing-tube machine.

[0078] In this step, after the heating furnace determines that the exhaust procedure needs to be executed, since the heating furnace is divided into plate changer and casing machine, the corresponding exhaust procedures are different, so it is necessary to determine whether the heating furnace is a plate changer or a casing machine. Since the heating furnace stores its own model parameters, it can be determined whether the gas heating furnace is a plate changer or a casing machine based on the model parameters.

[0079] It should be noted that the heating furnace model parameter is a combination of a group of numbers and letters, and the numbers and letters correspond to different meanings. The heating furnace can determine whether the heating furnace belongs to a plate changer or a casing machine according to a certain letter, a certain number, certain numbers, certain letters, or a combination of certain numbers and letters in the model parameter. The implementation of the present invention does not limit the heating furnace model parameter and the letters or numbers used to determine whether the gas heating furnace belongs to a plate changer or a casing machine, and can be set according to actual conditions.

[0080] S402: If the gas heating furnace is a plate heat exchanger, the three-way valve is controlled to be adjusted to the first position so that the heat exchanger is connected to the heating circuit.

[0081] In this step, the heating furnace determines whether the gas heating furnace belongs to a plate heat exchanger or a sleeve heat exchanger according to the model parameters of the heating furnace. If the gas heating furnace belongs to a plate heat exchanger, it is necessary to execute the exhaust program corresponding to the plate heat exchanger. The three-way valve is controlled to be adjusted to the first position, so that the heat exchanger is connected to the heating circuit, the water inlet of the three-way valve is connected to the heat exchanger, one water outlet of the three-way valve is connected to the heating circuit, and the other water outlet of the three-way valve is connected to the hot water circuit.

[0082] It should be noted that the three-way valve has a water inlet and two water outlets, and can be adjusted to two positions. When the three-way valve is adjusted to the first position, the heat exchanger is connected to the heating circuit; when the three-way valve is adjusted to the second position, the heat exchanger is connected to the hot water circuit.

[0083] S403: Controlling a water pump with a mechanical automatic exhaust valve to cycle for a first preset number of times, wherein each cycle includes rotating for a preset second time period and stopping for a preset third time period.

[0084] In this step, after the heating furnace controls the three-way valve to be adjusted to the first position, the heating circuit can be exhausted, and the water pump with a mechanical automatic exhaust valve is controlled to circulate for the first preset number of times, wherein each cycle includes rotating for a preset second time period and stopping for a preset third time period.

[0085] It should be noted that the first preset number of times, the preset second duration, and the preset third duration are set by the staff in the heating furnace before it leaves the factory, and are used to control the operation of the water pump. The first preset number of times can be 9 times, 5 times, or 10 times. The preset second duration can be 30 seconds, 20 seconds, or 50 seconds. The preset third duration can be 40 seconds, 20 seconds, or 10 seconds. The embodiment of the present invention does not limit the first preset number of times, the preset second duration, and the preset third duration, and can be set according to actual conditions.

[0086] S404: Control the three-way valve to the second position to connect the heat exchanger to the hot water circuit, control the water pump to rotate for the fourth preset time period, and control the three-way valve to the first position after the rotation time reaches the fourth time period, control the water pump to stop for the fifth preset time period, and repeat this step for the second preset number of times.

[0087] In this step, after the heating furnace discharges the bubbles in the heating circuit, the hot water circuit needs to be vented, the three-way valve is controlled to be adjusted to the second position to connect the heat exchanger with the hot water circuit, the water pump is controlled to rotate for the preset fourth time period, and after the rotation time reaches the fourth time period, the three-way valve is controlled to be adjusted to the first position, the water pump is controlled to stop for the preset fifth time period, and this step is repeated for the second preset number of times.

[0088] It should be noted that the second preset number of times, the preset fourth duration and the preset fifth duration are set by the staff in the heating furnace before it leaves the factory, and are used to control the operation of the water pump. The second preset number of times can be 9 times, 6 times, or 15 times. The preset fourth duration can be 30 seconds, 40 seconds, or 50 seconds. The preset fifth duration can be 30 seconds, 20 seconds, or 60 seconds. The embodiment of the present invention does not limit the second preset number of times, the preset fourth duration, and the preset fifth duration, and can be set according to actual conditions.

[0089] The gas heating furnace exhaust method provided in this embodiment exhausts the bubbles in the pipeline of the heating furnace by adjusting the position of the three-way valve and running the water pump. And by running and stopping the water pump in a cycle, the bubbles adhering to the inner wall of the pipeline can be smoothly discharged, effectively improving the exhaust efficiency.

[0090] The following describes the case where the heating furnace provided in the embodiment of the present invention is a casing machine.

[0091] After the heating furnace determines whether the gas heating furnace is a plate-changer or a sleeve-type machine based on the model parameters of the heating furnace, if the gas heating furnace is a sleeve-type machine, it is necessary to execute the exhaust program corresponding to the sleeve-type machine, and then control the water pump with a mechanical automatic exhaust valve to circulate for the third preset number of times, wherein each cycle includes rotating for a preset sixth time period and stopping for a preset seventh time period.

[0092] It should be noted that the third preset number of times, the preset sixth duration and the preset seventh duration are set by the staff in the heating furnace before it leaves the factory, and are used to control the operation of the water pump. The third preset number of times can be 18 times, 12 times, or 30 times. The preset sixth duration can be 30 seconds, 20 seconds, or 60 seconds. The preset seventh duration can be 40 seconds, 20 seconds, or 50 seconds. The embodiment of the present invention does not limit the third preset number of times, the preset sixth duration, and the preset seventh duration, and can be set according to actual conditions.

[0093] The gas heating furnace exhaust method provided in this embodiment exhausts the bubbles in the pipe of the heating furnace by running the water pump. And by running and stopping the water pump in a cycle, the bubbles adhering to the inner wall of the pipe can be smoothly exhausted, effectively improving the exhaust efficiency.

[0094] Figure 5 The schematic diagram of the process of the third embodiment of the gas heating furnace exhaust method provided by the present invention is as follows: Figure 5 As shown, in this embodiment, the gas heating furnace exhaust method also includes the following steps:

[0095] S501: During the execution of the exhaust procedure, detect whether the gas furnace has any fault.

[0096] In this step, for the safe operation of the heating furnace, during the exhaust procedure, it is detected whether the gas furnace has any faults.

[0097] Since the heating furnace is equipped with water pressure sensors, temperature sensors and other sensors, the heating furnace can use the sensors to detect in real time whether there is a fault in the gas furnace.

[0098] It should be noted that the fault may be a water shortage fault or an antifreeze fault. The embodiment of the present invention does not limit the fault, and it can be determined according to actual conditions.

[0099] S502: If there is a fault in the gas furnace, the exhaust procedure is stopped.

[0100] In this step, if the heating furnace detects a fault, for operational safety, it is necessary to stop the exhaust procedure and wait for maintenance or fault elimination.

[0101] S503: If it is detected that the fault is resolved, the exhaust procedure is executed again.

[0102] In this step, when the heating furnace detects through the sensor that the fault is rectified, since the exhaust is not completed at this time, the exhaust program needs to be executed again. The specific process of the exhaust program is similar to that of Example 2 and the example in which the heating furnace is a casing machine, and will not be repeated here.

[0103] The gas heating furnace exhaust method provided in this embodiment effectively ensures the safe operation of the heating furnace by detecting whether there is a fault during the exhaust process, and when a fault exists, eliminating the fault and then re-exhausting the gas heating furnace.

[0104] Figure 6 The schematic diagram of the process of the fourth embodiment of the gas heating furnace exhaust method provided by the present invention is as follows: Figure 6 As shown, in this embodiment, the gas heating furnace exhaust method also includes the following steps:

[0105] S601: In response to the opening of the gas valve, the valve opening time is obtained.

[0106] In order to determine whether to execute the exhaust procedure, the heating furnace needs to be determined based on the exhaust parameters and the valve opening time. The valve opening time refers to the total time the gas valve is open.

[0107] In this step, when the gas valve is opened, the heating furnace will obtain and store the valve opening time in real time.

[0108] It should be noted that the valve opening time is accumulated continuously. For example, when the gas valve is opened for the first time, the valve opening time starts from 0, and the first gas valve opening time is 3 minutes. When the gas valve is opened for the second time, the valve opening time starts from 3 minutes. The embodiment of the present invention does not limit the opening time of the gas valve each time, and it can be determined according to actual conditions.

[0109] S602: If the valve opening time exceeds the preset first time, the exhaust parameter is set to a second preset value.

[0110] In this step, the heating furnace will monitor in real time whether the valve opening time exceeds the preset first time according to the obtained valve opening time. If the valve opening time exceeds the preset first time, the exhaust parameter is set to the second preset value. If the valve opening time exceeds the first preset time, it means that the user has used the heating furnace for a period of time, and the bubbles in the pipeline have been exhausted. After the next startup, there is no need to perform the exhaust procedure again, so the exhaust parameter needs to be set to the second preset value.

[0111] It should be noted that the second preset value is set by the staff before the heating furnace leaves the factory, and is used to determine whether to execute the exhaust procedure. The second preset value is different from the first preset value, and the second preset value can be 0 or -1. The embodiment of the present invention does not limit the second preset value, and can be set according to actual conditions.

[0112] The gas heating furnace exhaust method provided in this embodiment sets the exhaust parameter to a second preset value when the valve opening time exceeds the preset first time, so that the heating furnace does not need to execute the exhaust procedure after the next startup, thereby reducing the time for water temperature to increase, speeding up heating efficiency, and improving user experience.

[0113] The following describes the situation where the exhaust parameter is not the first preset value or the valve opening time is greater than the preset first time.

[0114] If the exhaust parameter is not the first preset value or the valve opening time is greater than the first time, the exhaust procedure is not executed.

[0115] Since the exhaust program takes some time to execute, some users do not want to wait for the exhaust program to be executed after turning on the machine. They can ask after-sales personnel to modify the exhaust parameters to a value different from the first preset value. In this way, after the heating furnace is turned on, if the exhaust parameters are not the first preset value, the exhaust program will no longer be executed.

[0116] When the valve opening time exceeds the first preset time, it means that the bubbles in the heating furnace pipeline have been discharged.
