The anti-freezing pipeline is simple in structure, economical and environment-friendly, and can effectively solve the problem of frost cracking of the pipeline.
Description
Technical field
The present invention relates to the anti-freeze protection device of pipeline more particularly to a kind of antifreeze protector and use the antifreeze protector
Air-conditioner set.
Background technique
The pipeline of some electric appliances can also retain water after closing power supply and shutting down, and the water retained in winter manages in this way is very
It is easy to freeze, it can be pipeline bursting by freezing, in order to prevent this situation, tying up resistance wire or PTC heating on pipeline in the prior art
Bring and solve the problems, such as bursting by freezing, although may be implemented it is antifreeze, but a disadvantage is that can not solve the problems, such as unit power off.
Summary of the invention
In order to solve the problems, such as that the antifreeze power consumption of pipeline is big in the prior art, the invention proposes a kind of antifreeze guarantors of pipeline
Device is protected, the discharging valve including being set to pipeline water inlet solenoid valve rear end is serially connected the control switch for controlling the threshold switch that discharges water
And temperature detect switch (TDS), for providing the power module of electricity；Control switch closure when pipeline is not used by, the temperature control are opened
It closes and is closed when temperature is lower than set temperature.
In a specific embodiment, the control switch is water flow switch, and the water flow switch is normally-closed contact, works as pipe
Disconnection when having water-flow signal in road.The temperature detect switch (TDS) is normally opened contact.
Preferably, the discharging valve is set to the horizontal minimum point of pipeline.
Preferably, the power module includes rechargeable battery and charging circuit connected in parallel.
It preferably, further include the delay circuit being connect with the discharging valve.
The invention also provides the air-conditioner sets of the antifreeze protector for the pipeline being equipped in above-mentioned technical proposal.
Wherein the pipeline includes the water inlet pipe, outlet pipe and casing of air-conditioner set.Described in the power module connection
The power supply of air-conditioner set.
Power consumption needed for the present invention is low, can solve the problems, such as that cryogenic pipe is antifreeze independent of unit power supply, environmental protection section
Can, improve economy.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is circuit block diagram of the invention.
Fig. 2 is application schematic diagram of the present invention.
Specific embodiment
Fig. 1 gives a specific embodiment of the antifreeze protector of pipeline of the invention.The antifreeze protector includes electricity
Source module 1, water flow switch 2, temperature detect switch (TDS) 3 and discharging valve 4.The power consumption of the relative electronic components of antifreeze protector of the invention
Measure it is all lower, by the way that power module 1 is separately provided, so that antifreeze protector can solve the normal use after appliance cut-off and ask
Topic.
In a preferred embodiment, power module 1 includes rechargeable battery and charging circuit, when the antifreeze protector is installed
When on electric appliance, the power supply of 1 connecting circuit of power module can charge in this way during electric operation for rechargeable battery, so as to
After electric appliance closing, antifreeze protector can be operated normally.
Discharging valve 4 is mounted on pipeline water inlet solenoid valve rear end, is preferably mounted at the horizontal minimum point of pipeline structure, main
Acting on is draining.
Water flow switch 2 of the invention and temperature detect switch (TDS) 3 are connected, and the switch of control discharging valve 4 is cooperated to.Water flow switch
2 be normally-closed contact when normal, and when detecting has water-flow signal in pipeline, the electric appliance where illustrating pipeline is currently being used, this
When water flow switch 2 disconnect.It is normally opened contact when temperature detect switch (TDS) 3 is normal, when environment temperature is lower than preset temperature, temperature detect switch (TDS)
3 closures.Such as it can be decided whether to start anti-frost protection according to streamflow regime in pipeline at 0 DEG C of low temperature or less.
In the above-described embodiments, other than water flow switch 2, it can also can detecte whether pipeline is made with other
Control switch substitutes water flow switch, or detection electric appliance other control switches for whether being currently running substitute.May be used also
A delay circuit is arranged, after water flow switch 2 and temperature detect switch (TDS) 3 are all closed, delay a period of time triggers discharging valve 4 again
It opens, such as delay 5-10 minutes etc..
The present invention also protects the air-conditioner set using above-mentioned antifreeze protector.
As shown in Fig. 2, the pipeline of air-conditioner set includes the water inlet pipe 13, outlet pipe 14 and casing 15 of air-conditioner set, into
The first solenoid valve 11 and second solenoid valve 12 are respectively equipped at water pipe 13 and outlet pipe 14, antifreeze protector 10 is mounted on the first electricity
11 rear end of magnet valve, the power supply of the power module connection air-conditioner set of antifreeze protector 10.
In air-conditioner set normal course of operation, antifreeze protector 10 electric must charge simultaneously, and water flow switch 2 detects water-flow signal
Judge that channel interior there are water flow, judges that air-conditioner set is currently running (i.e. pipeline is currently being used), low temperature environment not
Can there are problems that frozen pipe, not implement anti-frost protection.
Assuming that preset temperature is 2 DEG C, when detecting water pipe water temperature inside lower than 2 DEG C, temperature detect switch (TDS) 3 is closed, remaining shape
State remains unchanged.When the water temperature in non-water flow signal and pipeline is lower than 2 DEG C, triggering discharging valve 4 is drained, and empties inlet tube and outlet tube
And the water of casing, it can at low ambient temperatures, automatic implementation anti-frost protection after unit power-off.The present invention is only when ability under low temperature environment
It can just trigger when being related to pipeline anti-frost protection and water temperature lower than 2 DEG C and when unit is out of service, stop in a preferred embodiment
It can be delayed 5-10 minutes and trigger after machine.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
