Description

Technical Field

[0001] The invention relates to the technical field of wall-mounted boilers, and in particular to a water outlet method and device for a wall-mounted boiler. Background Art

[0002] At present, the wall-mounted boilers on the market are used for both heating and bathroom. When users have bathroom needs, the wall-mounted boiler will give priority to meeting the bathroom water supply needs, and the heating will be turned off at this time. The end of the heating system of some families is a heat sink. When the user takes a bathroom for a long time, the heat sink dissipates heat quickly due to the long heating pause time, resulting in a rapid drop in indoor temperature, which brings a bad experience to the user. Therefore, a wall-mounted boiler with warm bath synchronization technology has appeared in China. The stepper motor of the three-way valve controls the ratio switching of bathroom / heating, so that a part of the heat can be allocated to heating while the bathroom is in use. However, the existing three-way valve stepper motor does not have the function of stroke feedback. When the bathroom and heating are in the heating state at the same time, the motor of the wall-mounted boiler fails, and the electronic control cannot identify it immediately. When heating, the wall-mounted boiler will continue to heat the bathroom water in the plate changer inside the machine. When the heating water outlet temperature is high, the bathroom water in the wall-mounted boiler plate changer is also high. When the user wants to take a bathroom, a section of high-temperature water will flow out when the hot water is turned on, which has the risk of scalding the user. Summary of the invention

[0044] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] The water outlet method of the wall-mounted boiler provided in the embodiment of the present application can be applied to the water outlet system of the wall-mounted boiler. Figure 1 As shown, the water outlet system of the wall-mounted boiler includes a controller 101 and a temperature probe 102, and the controller 101 and the temperature probe 102 are connected.

[0046] The controller 101 is used to receive the bathroom outlet water temperature sequence and the current heating outlet water temperature of the wall-mounted boiler sent by the temperature probe 102 after the heating is started. According to the bathroom outlet water temperature sequence, the temperature rise rate of the bathroom outlet water temperature is determined. If the temperature rise rate is greater than the preset temperature rise rate threshold, it is determined whether the wall-mounted boiler has a fault based on the current bathroom outlet water temperature and the current heating outlet water temperature. The current bathroom outlet water temperature is the bathroom outlet water temperature with the largest sampling time in the bathroom outlet water temperature sequence. If the wall-mounted boiler fails, the target heating outlet water temperature of the wall-mounted boiler is determined based on the user-preset heating outlet water temperature and the pre-stored anti-scalding outlet water temperature, and the heating water is controlled according to the target heating outlet water temperature.

[0047] The temperature probe 102 is used to detect the bathroom outlet water temperature sequence and the current heating outlet water temperature of the wall-mounted boiler, and send them to the controller 101.

[0048] The following will describe in detail a water outlet method for a wall-mounted boiler provided in an embodiment of the present application in combination with a specific implementation method. Figure 2 A flow chart of a water outlet method for a wall-mounted boiler provided in an embodiment of the present application, such as Figure 2 As shown, the specific steps are as follows:

[0049] Step 201, after the heating is started, the bathroom outlet water temperature sequence of the wall-mounted boiler and the current heating outlet water temperature are detected.

[0050] In practice, the wall-mounted boilers on the market are used for both heating and bathroom. When users have bathroom needs, the wall-mounted boiler will give priority to meeting the bathroom water supply needs, and the heating will be turned off at this time. The end of the heating system of some families is a heat sink. When the user takes a bath for a long time, the heat sink dissipates heat quickly due to the long pause time of heating, causing the indoor temperature to drop quickly, which brings a bad experience to the user. Therefore, wall-mounted boilers with warm-bath synchronization technology have appeared in China. The stepper motor of the three-way valve controls the ratio switching of bathroom / heating, so that part of the heat can be allocated to heating while taking a bath. However, the existing three-way valve stepper motor does not have the function of stroke feedback. When the bathroom and heating are in the heating state at the same time, the motor of the wall-mounted boiler fails, and the electronic control cannot identify it in the first time. When the stepper motor fails in the middle of the stroke, both the heating and bathroom sides will be heated. It is normal for the heating side to heat, but there will be problems if the bathroom side is heated all the time when there is no bathroom demand (no water flow), because the bathroom water of the wall-mounted boiler is heated at the plate heat exchanger. When there is no water flow in the bathroom, the water in the plate heat exchanger will continue to heat until it is as high as the heating water outlet temperature. Therefore, if the user sets a relatively high heating water outlet temperature, such as 80 degrees Celsius, the bathroom water in the plate heat exchanger will also be heated to 80 degrees. When the user turns on the bathroom water, the high-temperature water in the plate heat exchanger will come out and may scald people. Because the final heated temperature of the bathroom water is the heating water outlet temperature set by the user. Although there is not a lot of high-temperature hot water in the plate heat exchanger during this period, it may also cause a bad experience. Therefore, when heating, the wall-mounted boiler will continue to heat the bathroom water in the panel changer inside the machine. When the heating water temperature is high, the bathroom water in the wall-mounted boiler panel changer is also high. When the user wants to use the bathroom, when the hot water is turned on, a section of high-temperature water will flow out, which may scald the user. Therefore, after the heating is started, it is necessary to detect the bathroom water outlet temperature and the heating water outlet temperature of the wall-mounted boiler in real time. The subsequent steps also need to determine the temperature rise rate of the bathroom water outlet temperature, so it is necessary to obtain the bathroom water outlet temperature sequence. Therefore, after the heating is started, the bathroom water outlet temperature sequence of the wall-mounted boiler and the current heating water outlet temperature are detected.

[0051] Step 202, determining the temperature rise rate of the bathroom outlet water temperature according to the bathroom outlet water temperature sequence.

[0052] In practice, in heating mode, only the hot water for heating is heated, which is a normal situation when the stepper motor is not faulty. Because when only the hot water for heating is heated, the temperature rise of the bathroom water outlet is very slow. However, if the stepper motor fails in the middle stroke, the bathroom water will also be heated, and the temperature of the hot water in the bathroom water will rise faster. Therefore, the temperature rise rate of the bathroom water outlet temperature can be determined based on the bathroom water outlet temperature sequence. The subsequent steps are to reversely infer whether the stepper motor of the wall-mounted boiler is faulty based on the temperature rise rate of the bathroom water outlet temperature.

[0053] Step 203, if the temperature rise rate is greater than the preset temperature rise rate threshold, determine whether the wall-mounted boiler has a fault based on the current bathroom water outlet temperature and the current heating water outlet temperature. The current bathroom water outlet temperature is the bathroom water outlet temperature with the largest sampling time in the bathroom water outlet temperature sequence.

[0054] In implementation, after obtaining the temperature rise rate of the bathroom water outlet temperature, the temperature rise rate is compared with the preset temperature rise rate threshold. If the temperature rise rate is greater than the preset temperature rise rate threshold, it means that the stepper motor of the wall-mounted boiler may be faulty. Because, when the stepper motor is in normal operation, the temperature of the bathroom probe not only rises slowly, but also generally does not reach the heating water outlet temperature. But in the case of a fault, the temperature of the bathroom temperature probe rises quickly and can reach the heating water outlet temperature. Then, it is possible to infer whether the stepper motor is faulty through this difference. Therefore, after determining that the temperature rise rate of the bathroom water outlet temperature is greater than the preset temperature rise rate threshold, that is, after the bathroom probe temperature rises quickly, it is also necessary to determine whether the stepper motor is faulty based on the current bathroom water outlet temperature and the current heating water outlet temperature. Among them, the current bathroom water outlet temperature is the bathroom water outlet temperature with the largest sampling time in the bathroom water outlet temperature sequence. Among them, the preset temperature rise rate threshold can be 3K / S, and can also be other values ​​without limitation. Therefore, if the temperature rise rate is greater than the preset temperature rise rate threshold, it is determined whether the wall-mounted boiler is faulty based on the current bathroom water outlet temperature and the current heating water outlet temperature.

[0055] Furthermore, the specific steps of executing step 203 are as follows:

[0056] Step 1: compare the current bathroom water outlet temperature with the current heating water outlet temperature. If the current bathroom water outlet temperature is lower than the current heating water outlet temperature, it is determined that the wall-mounted boiler is not faulty.

[0057] In practice, when the stepper motor is in normal operation, the temperature of the bathroom temperature probe not only rises slowly, but also generally does not reach the heating water outlet temperature. However, in the case of a fault, the bathroom probe temperature rises quickly and can reach the heating water outlet temperature. Then, through this difference, it can be inferred whether the stepper motor is faulty. Therefore, under the premise that the temperature rise rate is greater than the preset temperature rise rate threshold, the current bathroom water outlet temperature and the current heating water outlet temperature are judged to determine whether the stepper motor of the wall-mounted boiler is faulty. If the current bathroom water outlet temperature is lower than the current heating water outlet temperature, it is determined that the wall-mounted boiler is not faulty.

[0058] Step 2: If the current bathroom water outlet temperature is equal to the current heating water outlet temperature, it is determined that the wall-mounted boiler has a fault, and a fault reminder is sent to the user to remind the user to troubleshoot the fault.

[0059] In practice, when the stepper motor is in normal operation, the temperature of the bathroom probe not only rises slowly, but also generally does not reach the heating water outlet temperature. However, in the case of a fault, the bathroom probe temperature rises quickly and can reach the heating water outlet temperature. Then, through this difference, it is possible to infer whether the stepper motor is faulty. Therefore, under the premise that the temperature rise rate is greater than the preset temperature rise rate threshold, the current bathroom water outlet temperature and the current heating water outlet temperature are judged to determine whether the stepper motor of the wall-mounted boiler has a fault. If the current bathroom water outlet temperature is equal to the current heating water outlet temperature, it is determined that the wall-mounted boiler has a fault. The user can be reminded to troubleshoot the fault by sending a fault reminder to the user. Among them, the fault reminder can be pushed through the APP, and the reminder information can be displayed on the display board to remind the user to troubleshoot the fault.

[0060] Furthermore, if the temperature rise rate is less than or equal to a preset temperature rise rate threshold, it is determined that the wall-mounted boiler has not failed.

[0061] In practice, when only the hot water for heating is heated, the temperature rise of the water outlet of the bathroom is very slow. However, if the stepper motor fails in the middle of the stroke, the bathroom will also be heated, and the temperature of the hot water in the bathroom will rise faster. If the stepper motor does not send a fault, the temperature rise rate of the probe temperature of the bathroom is slow. Therefore, if the temperature rise rate is less than or equal to the preset temperature rise rate threshold, it is determined that the wall-mounted boiler is not faulty.

[0062] Step 204, if the wall-mounted boiler fails, the target heating water outlet temperature of the wall-mounted boiler is determined according to the heating water outlet temperature preset by the user and the pre-stored anti-scalding water outlet temperature, and the heating water outlet is controlled according to the target heating water outlet temperature.

[0063] In practice, when the stepper motor fails in the middle of its stroke, both the heating and bathroom sides will be heated. It is normal for the heating end to heat, but there will be problems if the bathroom end is heated all the time when there is no bathroom demand (no water flow), because the bathroom water of the wall-mounted boiler is heated at the plate heat exchanger. When there is no water flow in the bathroom, the water in the plate heat exchanger will continue to heat until it is as high as the heating water outlet temperature. In other words, if the wall-mounted boiler fails, the bathroom water outlet temperature will reach the heating water outlet temperature. If the heating water outlet temperature is high, the user will be at risk of scalding in the bathroom. In order to avoid the risk of scalding to the user when the stepper motor fails, it is necessary to compare the user's preset heating water outlet temperature with the pre-stored anti-scalding water outlet temperature to determine whether the user's preset heating water outlet temperature will cause the user to be at risk of scalding, thereby avoiding the possibility of the user being scalded. Therefore, according to the user's preset heating water outlet temperature and the pre-stored anti-scalding water outlet temperature, the target heating water outlet temperature of the wall-mounted boiler is determined, and the heating water outlet is controlled according to the target heating water outlet temperature. In this way, even if the stepper motor fails, there will be no risk of scalding the user.

[0064] Furthermore, the specific process of executing step 204 is as follows:

[0065] Step A, compare the user-preset heating water outlet temperature with the pre-stored anti-scalding water outlet temperature. If the user-preset heating water outlet temperature is less than or equal to the anti-scalding water outlet temperature, the user-preset heating water outlet temperature is determined as the target heating water outlet temperature for the wall-mounted boiler.

[0066] In implementation, the user-preset heating water outlet temperature is compared with the pre-stored anti-scalding water outlet temperature. If the user-preset heating water outlet temperature is less than or equal to the anti-scalding water outlet temperature, it means that even if the stepper motor fails, the bathroom water outlet temperature will not reach the heating water outlet temperature, and high-temperature water that can scald people will not be generated, and the user will not be scalded. Among them, since the user will adjust the preset heating water outlet temperature, the user-preset heating water outlet temperature must be obtained again each time a fault judgment is made. Then the user-preset heating water outlet temperature can be determined as the target heating water outlet temperature for the heating of the wall-mounted boiler. Among them, the pre-stored anti-scalding water outlet temperature can be 60 degrees Celsius.

[0067] Step B: if the heating water outlet temperature preset by the user is greater than the anti-scalding water outlet temperature, the anti-scalding water outlet temperature is determined as the target heating water outlet temperature of the wall-mounted boiler.

[0068] In implementation, the user-preset heating water outlet temperature is compared with the pre-stored anti-scalding water outlet temperature. If the user-preset heating water outlet temperature is greater than the anti-scalding water outlet temperature, it means that if the stepper motor fails, the bathroom water outlet temperature reaches the heating water outlet temperature, and high-temperature water that can scald people is generated, which will scald the user. At this time, the user-preset heating water outlet temperature cannot be used as the target heating water outlet temperature, but the anti-scalding water outlet temperature is forcibly determined as the target heating water outlet temperature for heating of the wall-mounted boiler. Among them, the heating water outlet temperature can be controlled by the output power of the wall-mounted boiler, specifically by controlling the opening of the proportional valve and the speed of the fan, and the heating water outlet temperature is controlled by the power PI, so that the heating water outlet temperature is stabilized at the anti-scalding water outlet temperature.

[0069] Furthermore, if the wall-mounted boiler has not failed, the heating outlet water temperature preset by the user is determined as the target heating outlet water temperature for heating of the wall-mounted boiler.

[0070] In practice, when the stepper motor fails in the middle of the stroke, the water outlet temperature of the bathroom will reach the heating water outlet temperature, which may scald the user. Then, when the wall-mounted boiler is not faulty, there is no situation where the water outlet temperature is too high, so the user's preset heating water outlet temperature can be determined as the target heating water outlet temperature of the wall-mounted boiler.

[0071] The embodiment of the present application provides a water outlet method for a wall-mounted boiler, which can determine that the stepper motor may be faulty by the excessively high temperature rise rate. If the stepper motor is faulty, the bathroom water outlet temperature may rise to the heating water outlet temperature. If the heating water outlet temperature is too high, the user will be scalded when using the bathroom. Therefore, the target heating water outlet temperature of the wall-mounted boiler can be determined based on the current bathroom water outlet temperature and the current heating water outlet temperature. It can actively identify whether the stepper motor is faulty and avoid the generation of high-temperature water after a fault. No new parts are required to achieve control, and there is no cost increase. The patented control method is simple and effective, and can solve the abnormal risks of existing warm bath synchronization technology.

If the stepper motor is faulty, the bathroom water outlet temperature may rise to the heating water outlet temperature.

Therefore, the target heating water outlet temperature of the wall-mounted boiler can be determined based on the current bathroom water outlet temperature and the current heating water outlet temperature.
