Description

Technical Field

[0001] The present invention relates to the field of household appliance control technology, and in particular to a control method, device, equipment and storage medium for a wall-mounted boiler. Background Art

[0002] At present, when the fully premixed wall-mounted boiler is used in small-load operation to realize the "zero cold water" hot water preheating function, the minimum combustion load is large and the flow rate of the internal circulation pipeline is small, resulting in a large deviation in the water temperature between the nearest and farthest ends of the pipeline after the preheating is completed, resulting in a bad user experience and poor comfort.

[0003] Therefore, in order to solve the problem of poor user comfort caused by large water temperature deviation after the "zero cold water" hot water preheating function is running, it is generally necessary to add an additional hot water circulation tank to increase the circulating water capacity of the system for temperature buffering. However, such a configuration will lead to the problem of excessive cost. Summary of the invention

[0004] The present invention provides a control method, device, equipment and storage medium for a wall-mounted boiler, so as to realize the user's demand for preheating water, improve the user's comfort and reduce the cost at the same time.

[0005] In a first aspect, the present invention provides a control method for a wall-mounted boiler, comprising:

[0006] After controlling the wall-mounted boiler to operate according to the preset mode, obtain the real-time water temperature;

[0007] If the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated, wherein the fan speed reduction strategy includes at least two speed reduction stages, and the fan speed adjustment parameters of any two adjacent speed reduction stages are in a multiple relationship;

[0008] Control the fan speed of the wall-mounted boiler according to the fan speed reduction strategy.

[0009] The technical solution of the present invention provides a control method for a wall-mounted boiler, including: after controlling the wall-mounted boiler to operate according to a preset mode, obtaining the real-time water temperature; if the difference between the real-time water temperature and the target setting temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated, wherein the fan speed reduction strategy includes at least two speed reduction stages, and the fan speed adjustment parameters of any two adjacent speed reduction stages are in a multiple relationship; according to the fan speed reduction strategy, the fan speed of the wall-mounted boiler is controlled. In the above technical solution, after the user starts the "zero cold water" hot water preheating function, the wall-mounted boiler first operates according to the preset mode to obtain the real-time water temperature. If the difference between the real-time water temperature and the target setting temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated; and then the fan speed of the wall-mounted boiler is controlled according to the generated fan speed reduction strategy. Since the fan speed reduction strategy includes at least two speed reduction stages, the combustion load of the wall-mounted boiler can be gradually reduced, so that the water temperature deviation between the nearest and farthest ends of the pipeline is reduced after the "zero cold water" hot water preheating function is operated, thereby improving user comfort; at the same time, this solution does not require the addition of a hot water circulation tank, thereby reducing costs.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are only 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 should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] Figure 1 This is a flow chart of the control method of the wall-mounted boiler provided by the present invention. This embodiment is applicable to the case where the user needs to use the "zero cold water" hot water preheating function of the wall-mounted boiler. The method can be executed by a control device for the wall-mounted boiler, which can be implemented by software and / or hardware. Figure 1 As shown, the method specifically comprises the following steps:

[0027] Step 110: After controlling the wall-mounted boiler to operate according to the preset mode, obtain the real-time water temperature.

[0028] The preset mode is an operating mode of the wall-mounted boiler that is pre-set according to relevant information of the wall-mounted boiler before the wall-mounted boiler is used. The relevant information of the wall-mounted boiler may be at least one of power, model, brand, etc., which is not limited in this embodiment.

[0029] Specifically, after the user starts the "zero cold water" hot water preheating function, the wall-mounted boiler first operates according to the preset mode, and then uses the temperature sensor that comes with the wall-mounted boiler to obtain the real-time water temperature.

[0030] In this embodiment, after controlling the wall-mounted boiler to operate according to the preset mode, the real-time water temperature is obtained through the temperature sensor, which provides a data basis for the fan speed reduction strategy generated later and assists in completing the task of controlling the fan speed.

[0031] Furthermore, the preset mode includes a fire stabilization stage and a heating stage; controlling the wall-mounted boiler to operate according to the preset mode includes:

[0032] Controlling the wall-mounted boiler to operate at a steady-fire combustion load so that the wall-mounted boiler is in a steady-fire stage, and the duration of the steady-fire stage is a first preset duration;

[0033] The wall-mounted boiler is controlled to operate at a target combustion load so that the wall-mounted boiler is in a heating stage, wherein the target combustion load is greater than a steady-fire combustion load.

[0034] The steady fire stage is the stage in which the wall-mounted boiler is operated using the steady fire combustion load, and the heating stage is the stage in which the wall-mounted boiler is operated using the target combustion load. The steady fire combustion load is the combustion load set when the wall-mounted boiler is ignited, for example, one-third of the rated maximum load, and the target combustion load can be set according to the target set temperature. The first preset time length is the time required to operate using the steady fire combustion load to prevent the wall-mounted boiler from flameout.

[0035] Exemplarily, the fan speed matching the rated maximum load is 6000r, the fan speed matching the steady fire combustion load is 2000r, when the target set temperature is 42°C, the first preset time length is 3 seconds, and the fan speed matching the target combustion load is 4000r.

[0036] Specifically, when the user starts the "zero cold water" hot water preheating function, the wall-mounted boiler uses a steady fire combustion load for ignition. After successful ignition, the wall-mounted boiler runs with a steady fire combustion load for the first preset time to ensure that the wall-mounted boiler will not go out, and then switches the current load to the target combustion load according to the target set temperature, allowing the wall-mounted boiler to enter the heating stage.

[0037] In this embodiment, the wall-mounted boiler is prevented from flameout by running at a steady fire combustion load for a first preset period of time, and then runs at a target combustion load to enable the wall-mounted boiler to enter a heating stage, thereby assisting in realizing a "zero cold water" hot water preheating function.

[0038] Optionally, when the wall-mounted boiler uses a steady-fire combustion load for ignition operation, if the ignition fails, the ignition operation needs to be performed again. When the ignition operation is performed again three times and the ignition still fails, the locking program is started to lock the wall-mounted boiler to protect the safety of the user and prevent safety accidents.

[0039] Step 120: If the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated.

[0040] Among them, the real-time water temperature is the current temperature in the water pipe, the target setting temperature is the temperature set by the user according to his own needs, and the preset temperature is the conditional temperature set according to actual needs to determine whether to generate a fan speed reduction strategy. The fan speed reduction strategy may include the reduction rate of the fan speed, the minimum combustion load of the wall-mounted boiler, the number of speed reduction stages, the stage duration of each speed reduction stage, etc.

[0041] Optionally, in order to avoid the problem of large water temperature deviation between the nearest end and the farthest end of the pipeline and make the acquired real-time water temperature more accurate, temperature sensors can be respectively set at different positions of the pipeline, and the real-time water temperature can be calculated based on the water temperatures acquired by the temperature sensors at different positions. The calculation method can be a weighted method, an average method, a maximum / minimum value method, etc.

[0042] Specifically, after obtaining the real-time temperature, the difference between the real-time water temperature and the target set temperature is calculated. If the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, a fan speed reduction strategy can be generated according to the target combustion load and the steady-fire combustion load. After that, the wall-mounted boiler can start to reduce the load according to the fan speed reduction strategy, and finally the wall-mounted boiler can operate at the minimum combustion load. Among them, the fan speed reduction strategy includes at least two speed reduction stages, and the fan speed adjustment parameters of any two adjacent speed reduction stages are in a multiple relationship. For example, the fan speed adjustment parameter may include a decrease rate of the fan speed.

[0043] In this embodiment, the fan speed reduction strategy is used to assist the wall-mounted boiler to operate at the minimum combustion load to achieve the "zero cold water" hot water preheating function.

[0044] Furthermore, the method for generating a wind turbine speed reduction strategy may include the following four steps:

[0045] Step a: Determine the number k of speed reduction stages and the minimum combustion load corresponding to each speed reduction stage;

[0046] Step b: Determine the fan speed control parameters in the first speed reduction stage according to the target combustion load and the steady-fire combustion load;

[0047] Step c: for the 2nd to kth speed reduction stages, the adjustment parameters of the speed reduction stage are determined according to the minimum combustion load corresponding to each speed reduction stage and the minimum combustion load corresponding to the previous speed reduction stage, wherein the minimum combustion load corresponding to the last speed reduction stage is greater than the minimum operating load of the wall-mounted boiler;

[0048] Step d: According to the fan speed control parameters of the first speed reduction stage and the adjustment parameters of the second to kth speed reduction stages, the fan speed control parameters of the second to kth speed reduction stages are calculated in sequence.

[0049] In one possible implementation, before formulating the fan speed reduction strategy, a correspondence table is established between the rated maximum load, target combustion load and steady-fire combustion load of each wall-mounted boiler and the number k of speed reduction stages, the minimum combustion load corresponding to each speed reduction stage, the fan speed reduction rate and the fan speed.

[0050] Among them, the fan speed control parameters are parameters that can affect the fan speed, and may include the current fan speed, target combustion load, steady fire combustion load, maximum combustion load in the current deceleration stage, minimum combustion load, and fan speed reduction rate. The adjustment parameters in the deceleration stage are parameters that need to be adjusted in the deceleration stage, and may include the fan reduction rate. The adjustment parameters corresponding to each deceleration stage are in multiple relationship.

[0051] Specifically, the number k of deceleration stages and the minimum combustion load and the rate of decrease of the fan speed corresponding to each deceleration stage can be determined according to the established relationship table. First, the relationship table is checked based on the target combustion load and the steady-fire combustion load to determine the fan speed control parameters of the first deceleration stage, that is, the current fan speed, the maximum combustion load of the current deceleration stage, the minimum combustion load and the rate of decrease of the fan speed. Secondly, for the second to the kth deceleration stages, the relationship table is checked based on the minimum combustion load corresponding to each deceleration stage and the minimum combustion load corresponding to the previous deceleration stage to determine the adjustment parameters of each deceleration stage, that is, the rate of decrease of the fan speed. Then, according to the fan speed control parameters of the first deceleration stage and the adjustment parameters of the second to the kth deceleration stages, the fan speed control parameters of the second to the kth deceleration stages can be obtained by looking up the table.

[0052] For example, when the fan speed matched by the rated maximum load of the wall-mounted boiler is 6000r, the fan speed matched by the target combustion load is 4000r, and the fan speed matched by the steady-fire combustion load is 2000r, according to the relationship table determined above, it can be obtained that k is 2, the fan speed in the first speed reduction stage is a, the fan speed matched by the minimum combustion load is 1500r, and the fan speed decrease rate is 100 revolutions per second (r / s), the fan speed in the second speed reduction stage is b, the fan speed matched by the minimum combustion load is 1000r, and the fan speed decrease rate is 10r / s.

[0053] Exemplarily, when the fan speed matched by the rated maximum load of the wall-mounted boiler is 6000r, the fan speed matched by the target combustion load is 5500r, and the fan speed matched by the steady-fire combustion load is 2000r, according to the relationship table determined above, it can be obtained that k is 3, the fan speed in the first speed reduction stage is x, the fan speed matched by the minimum combustion load is 1500r, and the fan speed reduction rate is 100r / s, the fan speed in the second speed reduction stage is y, the fan speed matched by the minimum combustion load is 1250r, and the fan speed reduction rate is 20r / s, the fan speed in the third speed reduction stage is z, the fan speed matched by the minimum combustion load is 1000r, and the fan speed reduction rate is 10r / s.

[0054] In this embodiment, the fan speed reduction strategy is determined based on the fan speed control parameter, which improves the operating efficiency of the wall-mounted boiler and eliminates the need to add a hot water circulation tank, thereby reducing costs.

[0055] Accordingly, if the difference between the real-time water temperature and the target set temperature is greater than the preset temperature, the wall-mounted boiler is controlled to continue to operate at the target combustion load, and returns to execute the step of obtaining the real-time water temperature.

[0056] Specifically, after obtaining the real-time temperature, the difference between the real-time water temperature and the target setting temperature is calculated. If the difference between the real-time water temperature and the target setting temperature is greater than the preset temperature, the wall-mounted boiler continues to operate at the target combustion load, obtains the real-time temperature, recalculates the difference between the real-time water temperature and the target setting temperature and makes a judgment. The process is repeated until the difference between the real-time water temperature and the target setting temperature is less than or equal to the preset temperature.

[0057] Step 130: Control the fan speed of the wall-mounted boiler according to the fan speed reduction strategy.

[0058] Specifically, the fan speed of the wall-mounted boiler is controlled based on the fan speed reduction strategy determined above, that is, the fan speed reduction rate, the number of speed reduction stages, the minimum combustion load corresponding to each stage of the wall-mounted boiler, etc. Exemplarily, when the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, the combustion load of the current wall-mounted boiler begins to be reduced, and the fan speed of the wall-mounted boiler is controlled according to the fan speed reduction strategy, that is, the target combustion load, the steady-fire combustion load, the number of speed reduction stages, the fan speed reduction rate, etc.

[0059] In this embodiment, when the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, the combustion load of the wall-mounted boiler needs to be reduced to reduce power consumption, and there is no need to increase the hot water circulation tank, thereby reducing costs. According to the fan speed reduction strategy, the fan speed of the wall-mounted boiler is controlled, which not only achieves the purpose of reducing the combustion load of the wall-mounted boiler, but also avoids the problem of poor user comfort caused by large temperature deviation after the "zero cold water" hot water preheating function is running.

[0060] The technical solution of the present invention provides a control method for a wall-mounted boiler, including: after controlling the wall-mounted boiler to operate according to a preset mode, obtaining the real-time water temperature; if the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated, wherein the fan speed reduction strategy includes at least two speed reduction stages, and the fan speed adjustment parameters of any two adjacent speed reduction stages are in a multiple relationship; according to the fan speed reduction strategy, the fan speed of the wall-mounted boiler is controlled. In the above technical solution, after the user starts the "zero cold water" hot water preheating function, the wall-mounted boiler first operates according to the preset mode to obtain the real-time water temperature. Among them, the preset mode includes a steady fire stage and a heating stage. The wall-mounted boiler prevents it from being extinguished by running at a steady fire combustion load for a first preset time, and then runs at a target combustion load to make the wall-mounted boiler enter the heating stage, which assists in realizing the "zero cold water" hot water preheating function. Then the difference between the real-time water temperature and the target set temperature is calculated. If the difference between the two is less than or equal to the preset temperature, a fan speed reduction strategy is generated. The fan speed reduction strategy is used to assist the wall-mounted boiler to operate at the minimum combustion load to realize the "zero cold water" hot water preheating function. After that, the fan speed of the wall-mounted boiler is controlled according to the generated fan speed reduction strategy to reduce the minimum combustion load, thereby avoiding the problem of poor user comfort caused by large temperature deviation after the "zero cold water" hot water preheating function is operated. As a result, the water temperature deviation between the nearest and farthest ends of the pipeline is reduced after the "zero cold water" hot water preheating function is operated, improving user comfort. At the same time, there is no need to increase the hot water circulation tank, thereby reducing costs.

[0061] Figure 2 It is another flow chart of the control method of the wall-mounted boiler provided by the present invention. The embodiment of the present invention is applicable to the situation where the user needs to use the "zero cold water" hot water preheating function of the wall-mounted boiler. The embodiment of the present invention is optimized on the basis of the above embodiment, and the specific optimization is as follows: after controlling the fan speed of the wall-mounted boiler according to the fan speed reduction strategy, "obtaining the real-time water temperature; if the real-time water temperature is equal to the target set temperature, the wall-mounted boiler is controlled to be turned off, or the insulation program of the wall-mounted boiler is started", and the specific process of determining the adjustment parameters of the speed reduction stage from the 2nd to the kth speed reduction stage according to the minimum combustion load corresponding to each speed reduction stage and the minimum combustion load corresponding to the previous speed reduction stage is explained in detail. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. See Figure 2 The control method of the wall-mounted boiler provided in the embodiment of the present invention includes:

[0062] Step 210: After controlling the wall-mounted boiler to operate according to the preset mode, obtain the real-time water temperature.

[0063] Step 220: If the difference between the real-time water temperature and the target set temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated.

[0064] The method for generating a wind turbine speed reduction strategy may include the following four steps:

[0065] Step a: Determine the number k of speed reduction stages and the minimum combustion load corresponding to each speed reduction stage;

[0066] Step b: Determine the fan speed control parameters in the first speed reduction stage according to the target combustion load and the steady-fire combustion load;

[0067] Step c: for the 2nd to kth speed reduction stages, the adjustment parameters of the speed reduction stage are determined according to the minimum combustion load corresponding to each speed reduction stage and the minimum combustion load corresponding to the previous speed reduction stage, wherein the minimum combustion load corresponding to the last speed reduction stage is greater than the minimum operating load of the wall-mounted boiler;

[0068] For step c, the method for determining the adjustment parameters of the speed reduction stage may specifically include: obtaining the current operating time, target operating time and second preset time of the wall-mounted boiler, wherein the second preset time is the maximum time for the wall-mounted boiler to run at the minimum combustion load corresponding to the last speed reduction stage; according to the current operating time, target operating time and second preset time, respectively determine the stage durations of the 2nd to kth speed reduction stages; for the 2nd to kth speed reduction stages, determine the adjustment parameters of the speed reduction stage according to the minimum combustion load corresponding to each speed reduction stage, the minimum combustion load corresponding to the previous speed reduction stage and the stage duration of the speed reduction stage.

[0069] Specifically, the current running time, target running time and second preset time of the wall-mounted boiler are obtained, and the deceleration time can be calculated by subtracting the current running time and the second preset time from the target running time, that is, the total time required in the deceleration process, and then the stage time of the second to kth deceleration stages is determined based on the deceleration time. Optionally, the duration of each deceleration stage can be allocated in an average distribution manner or in a uniformly increasing manner, and this embodiment does not limit this. Exemplarily, when k=4, the deceleration time is 15s, and when the average distribution method is adopted, the stage duration of the second deceleration stage, the third deceleration stage and the fourth deceleration stage are all 5s. When k=4, the deceleration time is 18s, and when the uniformly increasing method is adopted, the stage duration of the second deceleration stage is 5s, the stage duration of the third deceleration stage is 6s, and the stage duration of the fourth deceleration stage is 7s. Afterwards, the minimum combustion load corresponding to each deceleration stage is obtained according to the aforementioned determined relationship table, and then the adjustment parameters of the deceleration stage are determined according to the minimum combustion load corresponding to each deceleration stage, the minimum combustion load corresponding to the previous deceleration stage and the stage duration of the deceleration stage. Exemplarily, when k=3, the fan speed matching the minimum combustion load corresponding to the first deceleration stage is 1500r, the stage duration of the second deceleration stage is 5s, the fan speed matching the minimum combustion load corresponding to the second deceleration stage is 1250r, the stage duration of the third deceleration stage is 10s, and the fan speed matching the minimum combustion load corresponding to the third deceleration stage is 1000r. The fan speed reduction rate of the second deceleration stage is 50r / s, and the fan speed reduction rate of the third deceleration stage is 25r / s.

[0070] In this embodiment, the stage durations of the 2nd to kth speed reduction stages are determined respectively according to the current operation duration, the target operation duration and the second preset duration, and then the adjustment parameters of the speed reduction stage are determined according to the minimum combustion load corresponding to each speed reduction stage, the minimum combustion load corresponding to the previous speed reduction stage and the stage duration of the speed reduction stage. This not only improves the operating efficiency of the wall-mounted boiler and reduces costs, but also allows the operating combustion load of the wall-mounted boiler to be more flexibly and quickly dynamically adjusted, thereby improving its flexibility.

[0071] Furthermore, the number of speed reduction stages included in the wind turbine speed reduction strategy is 2, and the adjustment parameter of the second speed reduction stage is 1 / n, where n≥5.

[0072] Specifically, the current operating time, target operating time and second preset time of the wall-mounted boiler are obtained, and the deceleration time, that is, the total time required in the deceleration process, is calculated by subtracting the current operating time and the second preset time from the target operating time. According to the target combustion load and the steady-fire combustion load, the fan speed control parameters of the first deceleration stage are determined, and then the stage time of the second deceleration stage is obtained by subtracting the stage time of the first deceleration stage from the deceleration time. Finally, the adjustment parameters of the second deceleration stage are determined according to the stage time of the second deceleration stage, the minimum combustion load, and the minimum combustion load corresponding to the previous deceleration stage, that is, the adjustment coefficient of the fan speed reduction rate, that is, 1 / n. Among them, the minimum combustion load corresponding to the previous deceleration stage is obtained by looking up the table. Exemplarily, when the fan speed matched by the target combustion load is 4000r, the fan speed matched by the steady-fire combustion load is 2000r, the current operating time of the wall-mounted boiler is 2 minutes, the target operating time is 6 minutes, the second preset time is 2 minutes, the stage duration of the first speed reduction stage is 1 minute, the fan speed matched by the minimum combustion load of the first speed reduction stage is 1500r, and the fan speed matched by the minimum combustion load of the second speed reduction stage is 1000r, it can be obtained that the stage duration of the second speed reduction stage is 1 minute, that is, 60s. After calculation, it can be obtained that n is 10, the original fan speed reduction is 100r / s, and according to the adjustment parameter 1 / n, it can be obtained that the current fan speed reduction is 10r / s.

[0073] It should be noted that the n in the adjustment parameter 1 / n of the second deceleration stage needs to be greater than or equal to 5, because when n is too small, the fan speed will be too high, which may cause the boiler to stall during the deceleration process. In addition, n is generally not greater than 20, because when n is too large, the fan speed will be too low, which may cause the boiler to fail to preheat within the scheduled time, affecting the user experience.

[0074] In this embodiment, when the number of speed reduction stages included in the fan speed reduction strategy is 2, setting the adjustment parameter of the second speed reduction stage to 1 / n can assist the wall-mounted boiler to better complete the speed reduction process, thereby improving user comfort.

[0075] Step d: According to the fan speed control parameters of the first speed reduction stage and the adjustment parameters of the second to kth speed reduction stages, the fan speed control parameters of the second to kth speed reduction stages are calculated in sequence.

[0076] Step 230: Control the fan speed of the wall-mounted boiler according to the fan speed reduction strategy.

[0077] Step 240: Get the real-time water temperature; if the real-time water temperature is equal to the target set temperature, control the wall-mounted boiler to turn off, or start the insulation program of the wall-mounted boiler.

[0078] Specifically, after the wall-mounted boiler's speed reduction process is completed according to the fan speed reduction strategy, the wall-mounted boiler operates at the minimum combustion load and obtains the real-time water temperature through the temperature sensor of the wall-mounted boiler. If the real-time water temperature is equal to the target set temperature, that is, the temperature required by the user is met, the wall-mounted boiler is turned off or the insulation program of the wall-mounted boiler is started.

[0079] In this embodiment, when the real-time water temperature is equal to the target set temperature, the wall-mounted boiler is turned off or the insulation program of the wall-mounted boiler is started to save power consumption and reduce costs.

[0080] The technical solution of the present invention provides a control method for a wall-mounted boiler, comprising: after controlling the wall-mounted boiler to operate according to a preset mode, obtaining the real-time water temperature; if the difference between the real-time water temperature and the target setting temperature is less than or equal to the preset temperature, a fan speed reduction strategy is generated, wherein the fan speed reduction strategy includes at least two speed reduction stages, and the fan speed adjustment parameters of any two adjacent speed reduction stages are in a multiple relationship; according to the fan speed reduction strategy, the fan speed of the wall-mounted boiler is controlled to obtain the real-time water temperature; if the real-time water temperature is equal to the target setting temperature, the wall-mounted boiler is controlled to be turned off, or the insulation program of the wall-mounted boiler is started. In the above technical solution, after the user starts the "zero cold water" hot water preheating function, the wall-mounted boiler first operates according to the preset mode to obtain the real-time water temperature. Then the difference between the real-time water temperature and the target setting temperature is calculated. If the difference between the two is less than or equal to the preset temperature, a fan speed reduction strategy is generated, and the fan speed reduction strategy is used to assist the wall-mounted boiler to operate at the minimum combustion load to realize the "zero cold water" hot water preheating function. Then, the fan speed of the wall-mounted boiler is controlled according to the generated fan speed reduction strategy to reduce the minimum combustion load, avoiding the problem of poor user comfort caused by large temperature deviation after the "zero cold water" hot water preheating function is running, thereby reducing the water temperature deviation between the nearest and farthest ends of the pipeline after the "zero cold water" hot water preheating function is running, improving user comfort and reducing costs. Finally, when the real-time water temperature is equal to the target set temperature, the wall-mounted boiler is turned off or the insulation program of the wall-mounted boiler is started, which reduces power consumption and saves resources.
