Description
The utility model relates to the improvement of hot-water heating valve, especially to the improvement of the water temperature control set for adjusting of infrared induction hot-water heating valve.
The hot-water heating valve of producing, selling and uying at present, especially the hot-water heating valve that utilizes infrared induction to control water outlet and close, its water temperature rectifying means all is the structure that adopts the manual tune hot and cold water, its operation is very loaded down with trivial details, and temperature is difficult to accurate control, because the hydraulic pressure of hot and cold water is undesired, cause water temperature fluctuated simultaneously, water-exit temperature is extremely unstable.
In view of the deficiency that prior art exists, the purpose of this utility model aims to provide a kind of hot-water heating valve of automatic adjusting water temperature.
Another purpose of the present utility model aims to provide a kind of automatic temperature-control hot-water heating valve of water temperature stability.
The utility model is finished as follows: the utility model comprises housing, inlet channel, water outlet, spool, valve shaft, the infrared inductor that is located at the water outlet place, the solenoid valve that is located at the water inlet and signal processing circuit, on the inwall of described water outlet, set up temperature inductor, on described valve shaft, set up gear pair, this gear pair is by the electric-motor-driving that is located in the housing, described temperature inductor is connected in signal processing circuit, this signal processing circuit control machine operation.
The utility model is provided with position limit switch and meets and discusses on described gear pair, the trip switch meet and discuss be located at housing on position limit switch cooperate the signal input signal processing circuit of described position limit switch.
Signal processing circuit described in the utility model is a cpu central processing unit.
Temperature inductor described in the utility model is temperature-sensitive electricity group RI.
Motor described in the utility model is a direct-flow deceleration electric motor.
The utility model compared with prior art has and adjusts the coolant-temperature gage function automatically, effluent temperature constancy, and the water-exit temperature error is controlled at ± and about 1 ℃, easy to use, health, quick.
The utility model has following accompanying drawing
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A cut-away view of Fig. 1
Fig. 3 is the plan view of Fig. 1
Fig. 4 is circuit theory diagrams of the present utility model.
Accompanying drawing has been represented structure of the present utility model, in conjunction with the embodiments structure of the present utility model and principle thereof is further elaborated below again.The utility model comprises housing 2, inlet channel 1, water outlet 5, spool 6, valve shaft 7, be located at the infrared inductor 4 at water outlet place, be located at the solenoid valve 12 and the signal processing circuit of water inlet, on the inwall of described water outlet 5, set up temperature inductor 3, on described valve shaft 7, set up gear pair 8, this gear pair 8 cooperates transmission by the motor 11 that is located in the housing 2, described temperature inductor 3 is connected in signal processing circuit, these signal processing circuit control motor 11 work.On described gear pair 8 position limit switch collision block 9 is set, the trip switch collision block 9 cooperates the signal input signal processing circuit of described position limit switch 10 with position limit switch 10 on being located at housing 2.Signal processing circuit described in the utility model embodiment is a cpu central processing unit, and described temperature inductor 3 is thermistor RI, and described motor 11 is a direct-flow deceleration electric motor.The utility model adopts motor 11 driven gear secondary 8 under the control of cpu central processing unit to rotate, and drives the inflow that spool 6 left rotation and right rotation realize regulating hot and cold water by valve shaft 7, thereby reaches the purpose of regulating actual water temperature by the set water temperature number of degrees automatically.
Use the utility model, at first want the set water temperature number of degrees, by adjusting thermal switch 13, the coolant-temperature gage numerical table 14 on the display board from Fig. 3 can be determined the water temperature number of degrees set.Pass to the infrared induction IC circuit when infrared rays inductor 4 obtains signal, change electrical signal into by IC and pass to CPU, CPU will send instruction unpack cool and thermal power magnet valve and make the water outlet water outlet.Temperature inductor 2 obtains signal and passes to CPU at this moment, calculate water temperature by CPU and whether reached the set water temperature number of degrees, if be higher than the set water temperature number of degrees, CPU then sends signal and passes to motor 11 and make its work, and driven gear secondary 8 rotates, thereby by valve shaft 7 rotational valve cores 6, suppose that the cold and hot water intake left side is that cold water, the right are hot water, so, described spool 6 will be turned left, the flow increase of cold water, the flow of hot water are reduced, reduce actual water temperature up to maintaining an equal level with the set water temperature degree thereby reach.Otherwise if actual water temperature is lower than the water temperature number of degrees of setting, motor 11 will drive spool 6 and turn right by gear pair 8, valve shaft 7 so, promptly heighten hot water flow and turn down the cold water flow, improve actual water temperature till maintaining an equal level with the water temperature of setting thereby reach.If actual water temperature has reached the water temperature number of degrees of setting, cpu central processing unit will not signal so, and motor 11 is not worked.When set water temperature is higher than the highest water temperature of hot-water heating valve hot water water inlet or is lower than the minimum water temperature of hot-water heating valve cold water water inlet, being located at position limit switch on the gear pair 8 meets and discusses and 9 will run into position limit switch 10, the signal input cpu central processing unit of position limit switch 10, cpu central processing unit sends signal and will control motor 11 and quit work, thereby locking spool 6 rotates, prevented in such cases the defective that spool 6 will unrestrictedly rotate when actual water temperature does not reach setting temperature.If the infrared inductor induction is that all remain static less than signal, waiting signal occurs so, and it is that the hot-water heating valve cuts out that cpu central processing unit is in off position.The utility model has solved the defective that former hot-water heating valve water temperature height is regulated by manual control, it is easy to operate, water temperature is accurate, constant, error is little, not only health but also quick is that the big wound to the water temperature regulation device of hot-water heating valve changes.
