Abstract
The invention provides a water-saving device for a solar water heater. The water-saving device is as follows: a piston is arranged inside a cylindrical water tank, wherein a water storage chamber is arranged on the upper side of the piston; a toothed bar which is connected to the lower side of the piston is tallied with and contact teeth of a gear which is arranged inside the water tank; a gear lever is fixed on a turntable of the gear, and can be hooked on a fixed hook on the lower side of the water tank when the piston is pulled downwards and driven to rise; and an interface is arranged on the water tank, is connected with a downcast pipe of the solar water heater, and is communicated with the water storage chamber on the upper side of the water tank. After the water-saving device is connected and communicated with the downcast pipe of the solar water heater, initial cold water in the downcast pipe can be completely absorbed and stored into the water storage chamber of the water tank when hot water of the solar water heater is used for a shower; and when the hot water is stopped to be used, the gear lever is pushed and the piston is driven to rise, and then the cold water is pressed into the downcast pipe, thereby the water-saving device can solve the waste phenomenon because the cold water is required to be let out when the hot water is used each time through repeated use.
Description
Technical field
The present invention relates to a kind of solar energy water heater device, a kind of specifically automatic regulating device for solar water heater.
Background technology
The present solar water heater that uses, owing to all be installed in the top of building, when using hot water, the cold water of being deposited in the sewer pipe must at first discharge totally, in use repeatedly, can cause great amount of water resources to waste.
Summary of the invention
The objective of the invention is to solve the waste problem of cold water discharging in the above-mentioned water heater down pipes road, a kind of automatic regulating device for solar water heater is provided, when using solar water heater hot water at every turn, cold water in the sewer pipe can be sucked and deposit, can effectively avoid the phenomenon of water resource waste.
The present invention includes water heater down pipes and piston and ratch, gear, the technical scheme that is adopted is: water saving fixtures are that a piston is housed in the cylinder water tank, the top of this piston is a water storage chamber, the teeth of institute's cogged are identical in the ratch that the below connects and the water tank touches mutually, be fixed with a rack on the wheel disc of described gear, this rack is pulled downwards when driven plunger rises and can be hooked on the stay hook of water tank downside, and the water tank top is provided with that interface is connected with the downcomer of solar water heater and communicates with water storage chamber above the water tank.
The present invention be connected with the sewer pipe of solar water apparatus communicate after, when using solar water heater hot water at every turn, can the cold water of being deposited in the sewer pipe all be sucked water storage chamber by rack regulating tank inner carrier, when stopping using hot water, by piston water is pressed in the sewer pipe again, when having solved existing solar water heater thus and using hot water at every turn, at first must rack up the problem of cold water in the sewer pipe, the good effect of have the conserve water resource, putting and ending to waste.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Shown in the accompanying drawing embodiment: water saving fixtures are that a piston 3 is housed in the cylinder water tank 1, the top of this piston 3 is water storage chambers 2, the ratch 4 that the below connects coincide with the teeth of water tank 1 interior institute cogged 5 and touches mutually, be fixed with a rack 6 on the wheel disc of described gear 5, this rack 6 is pulled when driven plunger 3 rises downwards and can be hooked on the stay hook 7 of water tank 1 downside, and water tank 1 top is provided with interface 8 and is connected with the downcomer 9 of solar water heater and communicates with the water storage chamber 2 of water tank 1 top.
