Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, there is provided a method for treating condensate water of a water heater, as shown in fig. 1, including:
step S110: and when the water heater is started in the zero cold water mode, detecting the state of a water pump of the water heater.
Specifically, when the water heater is switched on in the zero cold water mode, the state of a water pump of the water heater can be detected through the control device. The control device can adopt an independent controller or an original mainboard of the water heater. The user can set the mode through the remote controller or the control panel of the water heater, and whether the water heater is started in the zero cold water mode or not is selected. When the water heater is not in the zero-cold-water mode, the whole water heater unit belongs to a normal operation state, the main board normally operates according to a preset working program, for example, the heating power is adjusted by combining the temperature set by a user and the outlet water temperature of the water heater, the actual outlet water temperature is displayed through a display, and the like. At the moment, the water pump does not need to be started to work, and the anti-condensation device does not need to be started to work.
After the water heater is started in the zero cold water mode, the water pump starts to operate, and cold water in the water outlet pipe is pumped back to a heat exchanger of the water heater through the water inlet pipe to be heated. When the whole machine meets the water use requirement, namely the water temperature in the pipe between the water outlet end of the water heater and the water use point is larger than the set water temperature value of the whole machine system, namely the inlet water temperature reaches the set temperature value of the whole machine system, the zero cold water function is suspended, and meanwhile, the main board controls the water pump to stop running. After the water pump stops operating, the temperature difference is generated between the high temperature and the low temperature in the water inlet pipe of the water heater, and condensed water drops are easily generated on the pipe wall of the water inlet pipe. Therefore, when the water heater is switched on in the zero cold water mode, the control device determines the time for humidity detection by monitoring the state of the water pump.
Step S120: and when the water pump stops running, sending a detection instruction to the humidity detector.
The detection instruction is used for controlling the humidity detector to carry out humidity detection on the water inlet pipe of the water heater. The humidity detector can be specifically arranged on a water inlet pipe of the water heater, and the control device sends a detection instruction to control the humidity detector to carry out humidity detection on the water inlet pipe after detecting that the water pump stops running so as to analyze whether condensate water removal treatment needs to be carried out according to the humidity condition of the water inlet pipe. It can be understood that when the water pump still when the operation, then explain zero cold water function and still continuing, the inlet tube can not lead to producing the condensate drop because of the difference in temperature appearing this moment, and humidity detector need not to carry out humidity detection this moment, saves the electric energy and has prolonged humidity detector's life.
Step S130: and acquiring humidity data detected by a humidity detector. After the humidity detector detects the humidity data of the water inlet pipe, the control device directly receives the humidity data uploaded by the humidity detector.
Step S140: and when the humidity data meet the preset conditions, sending a starting signal to the anti-condensation device.
The starting signal is used for controlling the condensation preventing device to carry out condensate water removal treatment on the water inlet pipe of the water heater. The preset condition may be set according to actual conditions, for example, the preset condition may be that the humidity data is within a set humidity range, or the humidity data exceeds a set humidity threshold, or the like. Specifically, when the humidity data uploaded by the humidity detector exceeds a set humidity threshold value, the control device sends a starting signal to control the condensation preventing device to remove condensed water from the water inlet pipe, and the influence of the condensed water on the operation of the water heater is avoided. It can be understood that if the humidity data is not in accordance with the preset condition, the treatment of removing the condensed water is not needed, the anti-condensation device does not work, the electric energy can be saved, and the service life of the anti-condensation device is prolonged.
According to different specific structures of the condensation preventing device, the mode of removing the condensed water from the water inlet pipe is correspondingly different. The specific mode of the condensed water removing treatment can be selected according to actual requirements, for example, the condensed water on the water inlet pipe can be removed by selecting the modes of drying the water inlet pipe, heating and drying and the like. The proper blowing speed and heating power are only required to be controlled, and other devices of the water heater are not influenced in the process of removing the condensed water.
According to the method for treating the condensed water of the water heater, when the water heater executes a zero-cold-water function, when the water pump stops running, the temperature of water in the water inlet pipe of the water heater is changed from high to low, and the temperature difference can cause condensed water drops to be easily generated on the pipe wall of the water inlet pipe. When the humidity data that the humidity detector detected was through when accorded with the preset condition this moment, start anti-condensation device and carry out the comdenstion water and get rid of the processing, can effectively avoid the pipe wall of inlet tube to produce the comdenstion water, avoid the comdenstion water to corrode the water heater, improved the life and the safety in utilization of water heater.
In one embodiment, as shown in fig. 2, after step S140, the method further includes step S150.
Step S150: after the anti-condensation device works for a set time period, a stop signal is sent to the anti-condensation device, and the step S130 is returned to.
The starting signal is used for controlling the anti-condensation device to stop working. The value of the set time length is not only, and the time A seconds from generation to disappearance of condensed water in a natural state under the condition without the condensation preventing device in actual use can be analyzed and determined in advance, and the time A seconds is set as the set time length and is stored in the control device. After the anti-condensation device is started for a set time, the control device sends a stop signal to control the anti-condensation device to stop working, so that the electric energy waste caused by the over-long-time working of the anti-condensation device is avoided.
Furthermore, in one embodiment, after step S130, the method further comprises: and if the humidity data do not accord with the preset conditions, controlling the water heater to operate according to a preset working program. When the humidity data does not accord with the preset condition during the primary detection, or after the anti-condensation device works to enable the humidity data not to accord with the preset condition, the control device controls the water heater to operate according to a preset working program, for example, the heating power is adjusted by combining the temperature set by a user and the water outlet temperature of the water heater, the actual water outlet temperature is displayed through a display, and the like, so that the normal operation of the water heater is ensured. In addition, if the humidity data after being processed by the anti-condensation device does not accord with the preset conditions, the control device can also control the humidity detector to stop detecting.
In one embodiment, the condensation preventing device is a fan, and the step S140 includes: when the humidity data accord with the preset conditions, a starting signal is sent to control the fan to rotate at a set rotating speed, and the condensed water of the water inlet pipe is dried. In particular, it can be analyzed beforehand to ensure that the condensed water is not blown away, but only evaporated, corresponding to the rotation speed range. And determining a specific rotating speed value B according to the rotating speed range. When the water inlet pipe needs to be dried, the control device controls the fan to rotate at a rotating speed value B, so that the condensed water is ensured to be evaporated, and the influence of the condensed water on other devices is avoided.
In another embodiment, the condensation preventing device is a heating member, and the step S140 includes: when the humidity data accord with the preset conditions, a starting signal is sent to control the heating part to work with the set power, and the condensed water of the water inlet pipe is heated and dried. Similarly, the heating power range corresponding to the surrounding devices can be analyzed in advance to ensure that the heating heat does not affect the surrounding devices, and the specific power value C is determined according to the heating power range. When the inlet tube needs to be heated and dried, the control device controls the heating component to heat according to the power value C, so that the influence on other devices of the water heater is avoided.
In one embodiment, a device for treating condensed water of a water heater is also provided, as shown in fig. 3, including a state detection module 110, a humidity detection module 120, a data acquisition module 130 and an anti-condensation control module 140.

In order to facilitate a better understanding of the water heater condensate treatment method, apparatus, device and water heater system, a detailed explanation is provided below in connection with specific embodiments.
Traditional water heater is when using zero cold water mode, the system heating is taken out back through circulating water pump to the cold water section, in the circulation process, when the cold water in the inlet tube becomes hot water in heat exchanger, the circulating pump stop work, the unit begins to operate according to normal mode, the inlet tube temperature can become cold water this moment, the difference in temperature appears in this change stage, easily produce the comdenstion water, and heat exchanger generally adopts copper material to make, the heat exchanger pipeline can be corroded to the unit long-term use, reduce product life, the comdenstion water is if drop on electric elements or binding post, easily produce danger.
Based on this, this application provides a prevent that water heater from producing the scheme of comdenstion water, as shown in fig. 5, the water heater system includes heat exchanger, inlet tube, water pump, moisture detector, anti-condensing equipment and mainboard, advances water piping connection heat exchanger, and the water pump sets up in the inlet tube. The inlet tube at the water heater sets up moisture detector and anti-condensing equipment, and mainboard connection moisture detector and anti-condensing equipment, mainboard accessible link water pump control opening of water pump.
The water heater condensed water treatment process is as shown in fig. 6, when the function mode of the whole machine is not the zero cold water mode, the whole machine set belongs to a normal operation state at the moment, the water pump does not need to be started to work, the water temperature in the water inlet pipe is constant at the moment, condensed water is not easy to generate on the pipe wall, and therefore the anti-condensation device does not need to be started to work. When a user uses the zero-cold-water function, the water pump starts to operate, when the whole machine meets the water use requirement, namely the water temperature in the pipe between the water outlet end and the water use point is larger than the set water temperature value of the whole machine system, namely the water inlet temperature reaches the set temperature value of the whole machine system, the zero-cold-water function is suspended, and meanwhile, the water pump stops operating. After the water pump stops operating, the temperature difference is produced to the low temperature by height in the inlet tube, easily can produce the condensation drop on the pipe wall of outlet pipe, so when the water pump stops mainboard control moisture detector opens for detect near the humidity size of inlet tube, and feed back the numerical signal who detects to the mainboard. The main board is set with a humidity value in advance, when the numerical value detected by the detector is larger than or equal to the set value, the main board then gives a starting signal to the condensation preventing device, the condensation preventing device starts to work, the condensed water removing processing work is carried out on the water inlet pipe, after the condensation preventing device runs for A seconds, the time from generation to disappearance of the condensed water in the natural state of the condensed water when the condensation preventing device does not exist for A seconds, the main board gives a signal to the condensation preventing device again, at the moment, the condensation preventing device is in a closed state, meanwhile, the humidity detector continues to detect the humidity value, if the humidity value is still larger than or equal to the set value, the main board starts the condensation preventing device again to inhibit the generation of the condensed water, and the main board stops working naturally after the running.
Wherein, anti-condensation device can adopt the structure similar to little fan, and the mainboard controls the fan through the humidity numerical value that detects and rotates and stop, and the wind speed size can influence the comdenstion water and can not blown away, consequently can set for the rotational speed value for the fan in advance or set for the wind speed number and guarantee that the comdenstion water can not blown away, only can be evaporated. In addition, the condensation preventing device can also remove the condensed water by heating and drying, for example, the main board dries the condensed water by controlling the heating power of the condensation preventing device, and ensures that the heat does not affect the surrounding devices.
The method for judging the running state of the whole machine is utilized to control the condensation preventing device to prevent the surface of the pipeline from generating condensed water, so that the problems that the heat exchanger generates the condensed water to corrode a copper pipe in the zero-cold-water mode and the condensed water drops on electrical elements to cause danger are solved, and the service life of the product is prolonged.
