Abstract
The utility model discloses an inlet water controller of solar water heater, comprising a water tank and a ball float, wherein, a connecting rod is arranged inside the water tank through pin joint; one end of the connecting rod is connected with the ball float; an ejector pad is arranged on the other end of the connecting rod; a sliding rod which contacts the ejector pad and can move is arranged on the wall of the water tank; an offsetting spring applies force on the sliding rod to guarantee the contact of the sliding rod and the ejector pad; a contact is fixed on the other end of the sliding rod; a touch electric switch is fixed on the moving track of the contact; a thermoswitch is closely arranged outside the metal wall of the water tank; an inlet water control circuit is formed by the thermoswitch, the touch electric switch and a electromagnetic valve arranged on an inlet of the water tank. The utility model can control water inlet according to water temperature and water level, and not only the water temperature needed can be guaranteed but also the water tank can be guaranteed to stop feeding after the water tank is full of water. Simultaneously, a circuit is not immersed into hot water, so ageing, electrolysis polarization and fouling are not easy and the electrical property is stable, which is favorable to the service life.
Description
Technical field
The utility model relates to inlet control device, especially the inlet control device of solar water heater.
Background technology
Solar water heater, can provide the life usefulness hot water.Because the restriction of its mode of heating, the tap of can not fetching boiling water as gas heater just has hot water, and a water tank of storing hot water must be arranged.This water tank should not adopt the water inlet control of common ball float sealing formula, because use the ball float sealing, as long as the water of water tank does not reach just water inlet of peak level, when using hot water, just mend cold water simultaneously, but have little time to mend corresponding heat, may make the water temperature decline in the water tank can not satisfy required temperature.Existing electronic type automatic loading water device can be controlled in water inlet under the suitable water temperature condition, but because of its water level and cooling-water temperature sensor are inserted in the hot water, use some months just possibility electrolytic polarization, fouling, electrical property variation, its resistance value also can vary with temperature, and heat endurance and service life are not good enough.
Summary of the invention
The purpose of this utility model is to provide a kind of with water level, two condition control of water temperature water inlet, and component need not to be contained in the inlet control device in the hot water.
The inlet control device of solar water heater described in the utility model, comprise water tank, ball float, a hinged connecting rod in the water tank, one end of connecting rod connects ball float, the connecting rod other end is equipped with a pushing block, is equipped with one on the water tank wall and contacts with pushing block and sliding bar movably, have back-moving spring to the sliding bar application of force to guarantee contacting of sliding bar and pushing block, the sliding bar other end is fixed a contact, fixing actuating type electric switch on the motion track of contact; One thermoswitch is close to outside the water tank metallic walls, connects with actuating type electric switch, the magnetic valve that is contained in the water tank water inlet, constitutes the water inlet control circuit.
In order to show water level synchronously, described sliding bar outer end also can be moved with the moving plate of direct-push potentiometer linking to each other, and this direct-push potentiometer resistance output connects the unbalance bridge circuit pointer header.
Adopt inlet control device of the present utility model, ball float rises with water level during the water tank water filling, and connecting rod rotates around pin joint, and pushing block promotes slide bar and outwards moves.Meanwhile, the moving plate that sliding bar drives potentiometer moves moving, and the potentiometer output resistance changes, and the pointer header beat of pointer can show cistern water level by meter sense.Thermoswitch can be regulated the appropriate location and make it to cut off or connect circuit, and for example, water temperature is lower than 40C in water tank, and thermoswitch cuts off circuit, the magnetic valve outage, and water tank stops into water; When water temperature was higher than 50 ℃, thermoswitch was connected circuit, and water tank continues water inlet, and when water level rose to the spacing line of peak level, pushing block was pushed sliding bar to actuating type electric switch moving plate, and power supply disconnects, and radiotube controlling water tank stops into water.When water level decline, sliding bar resets under the effect of back-moving spring, leaves actuating type electric switch moving plate, and the actuating type electric switch is connected.As only working repeatedly.If water tank is filled with, solenoid control can not be intake; If water temperature is lower than design temperature, even water tank is not filled with, solenoid control can not be intake, and guarantees that the interior temperature of water tank is between 40～100 ℃.This device can advance water control according to water temperature and two conditions of water level, both can guarantee to satisfy required water temperature, can guarantee again to stop into water after water tank is filled with.Simultaneously, because component is not immersed in the hot water, be difficult for aging, electrolytic polarization, fouling, electric performance stablity, the service life that helps to improve device.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2, Fig. 3, Fig. 4 other several circuit diagrams of the present utility model.
The specific embodiment
As shown in Figure 1, having 17, the sliding bars 5 of housing that run through water tank wall to be placed in wherein and the energy move left and right near the tank top place, a back-moving spring 14 two ends link to each other with housing 17, sliding bar 5 respectively.Connecting rod 9 is hinged on the housing 17 that is in the water tank, and an end of connecting rod 9 is pushing block 4 (pushing block is an eccentric wheel in the present embodiment), and the other end connects ball float 10.The contact 18 of sliding bar 5 outer ends is facing to the moving plate 19 of actuating type electric switch 1.Direct-push potentiometer 2 is fixed on and is on the outer housing 17 of water tank, and its moving plate moves and just in time snaps in 20 in the draw-in groove 15 of sliding bar 5 belows, and sliding bar 5 moves the drive moving plate and moves and stir 20.The resistance output 3 of potentiometer 2 connects unbalance bridge circuit pointer gauge outfit (not shown), to show water level in the water tank.
Outside metallic walls 16 near the water tank bottom place, be close to a thermoswitch 11, an end of thermoswitch 11 is connected with entering water electromagnetic valve 7, and the other end is connected with the secondary coil of transformer 8.Actuating type electric switch 1 one ends are electrically connected with the city, and the other end is connected with the primary coil of transformer 8.Actuating type electric switch 1, thermoswitch 11 and magnetic valve 7 constitute the water inlet control circuit.
In order to prevent that the ball float afterbody from floating earlier and can not accurately reflect cistern water level, connecting rod 9 is connected an end with ball float 10 have a spacing card 16, guarantees that the ball float height is consistent with connecting rod 9 lower end height.
Establish a limit spring 13 on ball float 10, when water level rose to water level limit line 12, the restriction ball float continued to rise, guarantee pushing block 4 with major axis apart from a promotion slide bar 5, guarantee that kelly 18 pulls the moving plate 19 of actuating type electric switch 1 from outage.
The water inlet control circuit can also adopt other method of attachment, as Fig. 2, Fig. 3, shown in Figure 4, and all should be within protection domain of the present utility model.
