Description

Technical Field

[0001] The utility model relates to an auxiliary device for heating pipelines in winter, and particularly relates to an automatic air discharging device for household heating pipelines Background Art

[0002] Most families use radiators or buried pipelines for heating in winter. When the heating starts every year, there is more or less air in the heating system of each family, or the circulation speed is slow, which leads to a significant reduction in the heating efficiency and cannot meet people's needs. Currently, to solve the above problems, people usually manually open the air discharging valves of the radiators to empty or drain the heating system. Sometimes, after the air discharging is completed, it is necessary to empty the system again after a period of time, and it may even be necessary to empty or drain the system for many days and multiple times, or even multiple times a day. This working method requires professional operation or the operation of young people with air discharging experience. Moreover, it is difficult to control the air discharging time of the air discharging valves, and the air discharging time is uncertain, which wastes people's time and is time-consuming and laborious. The discharged sewage is easy to pollute the environment. In addition, some people drain the water continuously through the connecting hoses on the heating pipelines for convenience, resulting in waste of the circulating water in the heating system. Currently, there are more elderly people, women and children at home in society, and these people are unable to empty the heating system, which brings inconvenience to people's winter life Content of the Utility Model

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Embodiment 1: Referring to Figure 1 , Figure 2 , Figure 8 , Figure 9 , a household heating pipe automatic drainage device includes a control box 1 and a solenoid valve 2. The control box 1 is electrically connected to the solenoid valve 2. The housing 101 of the control box 1 is a waterproof box body structure with an internal cavity and capable of opening the front cover, which is rectangular or circular. The input end of the solenoid valve 2 is connected to the radiator 3 at the highest point of the heating pipe or on the heating pipe, and the inner cavity of the solenoid valve 2 is connected to the inner cavity of the heating pipe. The output end pipe 4 of the solenoid valve 3 is connected to the sewer or toilet; a temperature controller 5, a water level controller 6, a power module 7, a lithium battery 8, and a timing module 9 are installed in the housing 101. A power socket 10 and a wiring port 11 are provided on the lower side surface of the housing 101. The power socket 10 is electrically connected to the power input end of the power module 7, the lithium battery 8 is electrically connected to the battery connection end of the power module 7, the output end of the power module 7 is electrically connected to the power end of the timing module 9 through a power switch 12, and the output end of the timing module 9 is electrically connected to the solenoid valve 2 through the wiring port 11; the temperature controller 5 is a digital microcomputer temperature switch. The display and adjustment panel 51 of the microcomputer temperature switch is exposed on the front side surface of the housing 101 for convenient observation and adjustment. The sensor 52 of the digital microcomputer temperature switch is embedded in the rear bottom surface inside the housing; the water level controller 6 is a non-contact ultrasonic liquid level sensor, embedded in the rear bottom surface inside the housing 101, with the sensing surface facing the outside of the bottom surface of the housing. Its control end is connected in parallel with the control end of the temperature controller 5 to the trigger end of the timing module 9. A permanent magnet 13 or an adhesive sticker is provided on the rear box surface of the housing 101.

[0029] The power module 7 is a lithium battery charge and discharge integrated boost power module, and the charging interface of this lithium battery charge and discharge integrated boost power module is the power socket 10. The timing module 9 is a cyclic timing control module provided with a trigger end.

[0030] In use, first connect the output plug of the mobile phone charger to the power socket 10 on the housing 101 of the control box 1 to charge the internal lithium battery 8 of the control box 1 using the mobile phone charger. After charging is completed, unplug the charger and use it, enabling the present utility model to work completely independent of the mains power supply, which is safe and reliable. Attach the control box 1 to the radiator 3 at the highest point of the heating pipe (usually installed at three-fourths of the total height of the radiator or at the highest point) through the permanent magnet 13 or adhesive sticker on the back of the housing 101 of the control box 1, and electrically connect the wiring port 11 to the solenoid valve 2. Set the control temperature of the control box 1 (usually set to 25 - 35°C) lower than the normal heating temperature of the radiator (usually set to 35 - 50°C) through the display and adjustment panel 51 of the microcomputer temperature switch. After turning on the power switch 12, the timing module 9 enters the standby working state. When the temperature on the radiator is lower than the set value, it indicates insufficient heating. At this time, the control terminal of the temperature controller 5 is connected, and the trigger terminal of the timing module 9 receives a trigger level. Its output terminal then outputs power in a timed cycle to drive the solenoid valve 2 to open and close periodically, draining or filling the radiator 3 to promote the circulation of the heating pipe. During this process, if the temperature on the radiator 3 is higher than the set value, the control terminal of the temperature controller 5 is disconnected, the trigger terminal of the timing module 9 loses the trigger level, and its output terminal no longer outputs power, and the solenoid valve 2 automatically closes. The time for the timing module 9 to output power in a timed cycle is generally set to open the solenoid valve 2 for 1 - 10 minutes and then close it for 15 - 30 minutes before controlling it to open again, and so on until the temperature on the radiator 3 reaches the set value.

[0031] The function of the water level controller 6 is to monitor the water level of the radiator 3 at the highest point of the heating pipe. When the water level of the radiator 3 is lower than the position of the non-contact ultrasonic liquid level sensor 6, the output terminal of the non-contact ultrasonic liquid level sensor 6 closes, and the trigger terminal of the timing module 9 receives a trigger level, thereby cyclically and periodically controlling the opening and closing of the solenoid valve 2 to achieve the draining work of the heating pipe.

[0032] Embodiment 2: Referring to the attached drawings 3, attached Figure 4 attached Figure 8 attached Figure 9 In this embodiment, the sensor 52 of the digital microcomputer temperature switch and the water level controller 6 using a non-contact ultrasonic liquid level sensor respectively extend outside the housing 101 through the wiring port 11 and are installed on the radiator or heating pipe at the highest point of the heating pipe. The remaining structures and working principle processes are the same as those in Embodiment 1.

[0033] Embodiment 3: Referring to the attached Figure 5 attached Figure 6 attached Figure 8 attached Figure 9, in this embodiment, the temperature controller 5 is a liquid expansion type temperature switch. The action contact of the liquid expansion type temperature switch is connected to the trigger end of the timing module 9. Its sensing head 53 is embedded in the rear bottom surface inside the housing 101 or led out of the housing and installed on the radiator or heating pipe at the highest point of the heating pipe. The temperature adjustment knob 54 of the liquid expansion type temperature switch is arranged on the front side surface of the housing 101, which is convenient for observation and adjustment. The remaining structures and working principle processes are the same as those in Embodiment 1 and / or Embodiment 2.

[0034] Embodiment 4: Refer to the attached Figure 3 and the attached Figure 4 and the attached Figure 5 and the attached Figure 6 and the attached Figure 7 and the attached Figure 8 and the attached Figure 9 , in this embodiment, the water level controller 6 is or a probe type sensor 61. The probe type sensor 61 extends outside the housing 101 through a wire and is installed in the radiator or heating pipe at the highest point of the heating pipe, and it can sense whether there is water at the highest point of the heating pipe. The probe type sensor 61 includes a plug 611 made of insulating material. Two probes 612 are penetrated through the middle of the inside of the plug 611. Line connection ends 613 are arranged at the ends of the two probes 612 outside the plug 611 for connecting to the trigger end of the timing module 9. The two probes 612 are spaced at least 2 millimeters apart, and they extend 5 - 16 centimeters inside the plug 611.

[0035] During use, replace the metal plug at the top of the radiator with the probe type sensor 61 of this embodiment, and insert the two probes 612 into the radiator. When the water level in the radiator is relatively high, both probes 612 are immersed in water, which is equivalent to a resistor with a relatively small resistance value. When air appears in the radiator and the water level is lower than the probes, the resistance between the two probes 612 increases greatly. The timing module 9 is triggered by the large difference in the resistance values of the two probes 612. When the resistance between the two probes 612 is relatively small, the timing module 9 does not work. When the resistance is relatively large, the timing module 9 outputs a drive signal to open and close the solenoid valve 2 periodically to empty the radiator. The remaining structures and working principle processes refer to Embodiment 1 and / or Embodiment 2 and Embodiment 3.

[0036] In the above-mentioned various embodiments, the temperature controller, water level controller, power supply module, lithium battery, timing module, and relay module are all existing technology molded products and can be directly purchased. After the installation of the present utility model is completed, the wiring port 11 is sealed with waterproof glue, and a detachable waterproof cover is provided on the power socket 10 for waterproofing. The trigger end of the timing module can be set between high-level trigger and low-level trigger to be applicable to the outputs of the temperature controller and the water level controller.
