Abstract

The utility model relates to a water heater which utilizes the heating of a heating line, and hot water can be pushed out through utilizing pushed pistons and the internal pressure of a tapping pipe. The utility model is characterized in that a water tank and a piston are all cannibalization components, Eccentric through holes on the heating line are adopted, the installation can be simplified, and the limitation of the distance between the heating line and a wall can be avoided. The mixing of the cold and hot water can be eliminated, and the force transmission can be guaranteed through the isolation function of the piston. Thus, leaving water temperature is constant, and enough lifting force can be provided. The direction of hot water pushed by the piston can be controlled by a conversion valve. A summarization accompanying diagram (specification accompanying diagram 8) shows that the utility model comprises a water box 1, the heating pipe 2, a left port 3, the piston 4, a right port 5, the conversion valve 6, a water inlet port 7, and a water outlet port 8.

Description

Energy-saving water heater

The utility model belongs to a kind of heat-exchange device, is the heat that utilizes caliduct, the cold water in the heating water tank, the water heater of the usefulness of the washing in winter of confession family, bathing.

Existing this type of device mainly exists heat exchanger effectiveness low, and discharge pressure is little, installs complicated and dangerous.

The purpose of this utility model is to improve firing rate, and the hot water temperature is constant during the water, guarantees the height that rises of water outlet, simplifies construction technology.

Design feature of the present utility model is achieved purpose of design.Its core is that the moulding and the material of water tank is beneficial to the heat exchanger effectiveness raising, and the intervention of piston has also been avoided the variation of leaving water temperature except the pressure that keeps water outlet.

Be illustrated below in conjunction with accompanying drawing.

Fig. 1 is the front view of water tank.

Fig. 2 is the bottom view of Fig. 1.

Fig. 3 is the right view of Fig. 1.

Water tank does not add interior cover, and working medium (cold water) directly contacts with thermal source (caliduct), the heat conduction efficiency height, and programming rate is fast.

The water tank overcoat is selected the good plastic material of heat-proof quality for use, reduces heat conduction and the heat radiation of overcoat to air as far as possible, and heat leakage is little, good heat insulating.

Cisten mechanism is designed to assembly component, and the heating equipment of heating installation need not done any tearing down and reconstructing, and just can install with extremely easy operation, not only rapidly but also safety.

The off-centre of the caliduct perforation of water tank makes the water tank diameter not be subjected to the distance limit of caliduct and metope.The step reducing in this hole makes the scope broadening of adaptive caliduct caliber, exempts from out how secondary water tank mould.

Fig. 4 is the front view of piston.

Fig. 5 is the right view of Fig. 4.

Fig. 6 is the A-A cutaway view of Fig. 4.

Under the conventional state, water is incompressible fluid.When not putting hot water, piston pressure at both sides balance.When hot water is emitted, the pipe internal pressure of running water, side at piston keeps malleation, hot water one side of piston will present negative pressure, cold inevitable mobile so live to negative pressuren zone (hot water side), therefore, the pipe internal pressure of the running water that passes over, hot water is extruded with certain flow velocity, guaranteed its height that rises.This makes the installation site of water tank and mode along the caliduct tendency, can height can be low, can found dress, dress can crouch.

In view of the buffer action of piston, replenish cold water, extrude in the process of hot water, do not exist because of stirring of producing of convection current and convert, so hot water is temperature-resistant up to draining.

The eccentric reducing step of the caliduct perforation of piston, it is also tight to make piston cooperate with water tank and caliduct.

In case piston moves to the water tank top, if put the hot water of new heating again, the opposite side that cold water can only change by piston injects, and this conversion is finished by switching valve.When its guide plate reverses 90 °, the combination of the four-way of switching valve changes, and causes to flow to conversion.Square switching valve schematic diagram Fig. 7 to control.

As can be seen, regardless of the piston direction of motion, the flow direction of import and export is forever constant.Workflow such as Fig. 8.

In the utility model Figure of description:

1---water tank; 7---water inlet (cold water);

2---hot duct; 8---delivery port (hot water);

3---left circulation port (being called for short left side mouth); 9---the assembly unit muscle;

4---piston; 10---observation window;

5---right circulation port (being called for short right mouthful); 11---the caliduct perforation;

6---switching valve; 12---the assembly unit hasp; Solid line---cold water injects water tank by right mouthful 5, and hot water is clamp-oned switching valve by water tank through left side mouth 3, derives from delivery port again.Dotted line---cold water is by a left side mouthful 3 injection water tanks, and hot water is clamp-oned switching valve by water tank through right mouth 5, derives from delivery port again.
