Abstract

The utility model provides a solar water heater comprising a thermal insulation water bucket, water charging and discharging pipes, a water charging check valve, an air intake valve, a pull wire, a pull switch, a water charging and discharging switch, and a draining switch. The water charging check valve is pushed open by water pressure during a water charging process, and returns back to the original position under the spring force of the water charging check valve when water charging is completed, so that return flow of water in the thermal insulation water bucket can be prevented. When antifreeze operation is required, the draining switch can be opened, so that water runs down under gravity, and the air intake valve is opened to fill the drained pipe with air and to facilitate completely draining of the water charging pipe. When one wants to use water, the pull switch can be rotated, so that a connection finer is inserted into the pipe via a rubber seal and pulls a mobile guide rod which pushes open the water charging check valve. Hot water, then, runs down, and water is heated instantly once the pull switch is opened. When one finishes using water, the pull switch can be rotated back, and a return extension spring pulls back the mobile guide rod.

Description

Solar water heater

Technical field:

The utility model relates to a kind of solar utilizing equipment, the antifreeze emptier of especially a kind of solar water heater.

Background technology:

In the prior art; Known solar water heater; It is the utility model patent of < a kind of intelligent emptying appearance that is used for solar water heater>of State Intellectual Property Office's bulletin; The patent No.: 200920317744, the utility model discloses a kind of technical scheme that is used for the intelligent emptying appearance of solar water heater, comprise master machine control unit, magnetic valve, exhaust-valve, exhaust-valve motor, draining valve, draining valve motor, sensor and float-ball type air inlet pipe; Wherein magnetic valve, exhaust-valve motor, draining valve motor and sensor all are connected with master machine control unit through holding wire; Magnetic valve is positioned at inlet channel, and exhaust-valve and draining valve are positioned at outlet conduit; The exhaust-valve motor is connected on the exhaust-valve, and the draining valve motor is connected on the draining valve; One end of sensor is placed in the water tank; One end of float-ball type air inlet pipe is positioned at the valve core of exhaust-valve, and the other end floats on the surface.The utility model is through the intellectuality operation of solar water heater; Make the automatic emptying of water in the outlet conduit; Prevent the bursting by freezing of water pipe in winter, improved the heat insulation effect of water tank, make the user once the hot water of turning on the tap out; Change water heater and put the history that cold water goes out hot water more for a long time earlier, practiced thrift water resource simultaneously.But: the technical scheme of this patent, structure are too complicated, have increased manufacturing cost and customer using cost, and power failure can not be operated, and this is the existing in prior technology weak point.

Summary of the invention:

The purpose of the utility model; Be exactly not enough to existing in prior technology; And the technical scheme of the antifreeze emptier of a kind of solar water heater, this scheme are provided is one way stop peturn valve of opening in the same way and the mechanically controlled switch system of setting up in the water inlet of solar water heater insulation water butt; Reach the upper hose evacuation and anti-freezing, the purpose of following water instant-heating.

This programme is realized through following technical measures: include insulation water butt, upper and lower conduit road, go up Water Check Valve, intake valve, pulling steel wire, Drawing switch and up and down taps emptying switch form, when on the solar energy during water, hydraulic pressure is pushed Water Check Valve open, when stopping upward water; Last Water Check Valve is return under the effect of spring force, and the water of insulation in the water butt can not be refluxed, and opens the emptying switch in the time of need be antifreeze, and water is in the self gravitation refluxed; This moment, INO was mended into air, made in the upper hose to be emptied completely, and during water, rotated Drawing switch; Connect finer wire pulling activity guide rod also in rubber seal penetrates pipe, movable guide rod is pushed Water Check Valve open, and hot water immediately flows down; Instant-heating uses up and goes back to Drawing switch, returning pull-spring pulling activity guide rod return; Then go up the Water Check Valve return, turn-off current, this moment, intake valve was opened under atmospheric pressure automatically; Till treating that current in the upper hose are intact, because of last Water Check Valve and the equidirectional installation of intake valve, during last water on the Water Check Valve unlatching; Intake valve cuts out, and goes up Water Check Valve during emptying and closes inlet open.Described finer wire is used stainless steel wire, and described movable guide rod and return spring are used stainless steel material equally, and described upward Water Check Valve is identical with intake valve, selects the ready-made inside and outside silk brass check-valves in market for use.

The beneficial effect of this programme can be learnt according to the narration to such scheme, owing in this scheme, select mechanical structure for use; Cost easy to manufacture is low, and not receiving to have a power failure influences, and is easy to operate during work; Thoroughly solved the antifreeze problem of upper and lower conduit, instant-heating during use has been removed the cold water that must bleed off earlier before the water in the water pipe from; Promptly practiced thrift water, need not wait for the time of hot water again, this shows; The utility model compared with prior art has substantial characteristics and progress, and the beneficial effect of its enforcement is conspicuous.

Description of drawings:

Fig. 1 is the structural representation of the utility model specific embodiment.

Among Fig. 1,1 is taps up and down, and 2 are the insulation water butt, and 3 be last Water Check Valve, and 4 be movable guide rod, and 5 is returning pull-spring, and 6 is intake valve, and 7 is finer wire, and 8 is rubber seal, and 9 is Drawing switch, and 10 is the emptying switch.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below through a specific embodiment, and combine its accompanying drawing, this programme is set forth.

Can find out through accompanying drawing; The antifreeze emptier of the solar water heater of this programme; The upper and lower conduit of taps (1) and emptying switch (2) about including; Rubber seal (8) is installed in elbow at upper and lower conduit, penetrates thin guiding principle silk (7) in the center of rubber seal (8), and lower end connection Drawing switch (9) upper end of finer wire (7) is connection activity guide rod (4) through the upper hose center; Movable guide rod (4) is pind down by returning pull-spring (5), on the water inlet of insulation water butt (2), connects Water Check Valve (3) and intake valve (6).

Claims

1. solar water heater, include insulation water butt, upper and lower conduit road, go up Water Check Valve, intake valve, pulling steel wire, Drawing switch and up and down taps emptying switch form, when on the solar energy during water; Hydraulic pressure is pushed Water Check Valve open, and when stopping to go up water, last Water Check Valve is return under the effect of spring force; Water in the insulation water butt can not be refluxed; Open the emptying switch in the time of need be antifreeze, water is in the self gravitation refluxed, and this moment, INO was mended into air; Make in the upper hose and be emptied completely; Drawing switch connects finer wire in rubber seal penetrates pipe and pulling activity guide rod, and movable guide rod is pushed open or closed and closes Water Check Valve, it is characterized in that: described go up Water Check Valve select for use with intake valve inside and outside a brass check-valves.
