Description

A kind of electric heater of cold-hot water separating

Technical field：

The utility model is related to pot-type boiler field of energy-saving technology, specifically a kind of to be shared come real by hot and cold water Existing energy-efficient device.

Background technology：

Currently, being generally horizontal type structure for electric heater, intake using liner at the bottom, original hot water leans on certainly in water tank The pressure of water, top is arrived on top, since hot water density is small, liner top is always floated on after being heated, after cold water enters from bottom Hot water is squeezed, and is squeezed out from the water outlet tube opening on liner top, hot water is caused to flow out, to achieve the purpose that heating uses； This mode of heating in use, due to cold water entrance, the hot and cold water in water tank is in direct contact, and causes the water temperature in water tank continuous Decline, when especially having a bath, need to constantly adjust water temperature, until the water temperature in water tank is down to and can not be used, such part hot water obtains Less than making full use of, the heat exchange generated so as to cause hot and cold water is big, and big energy-consuming is unfavorable for energy conservation and environmental protection.

Invention content：

The purpose of the utility model is to overcome the deficiencies of above-mentioned prior art, and provide a kind of electric hot water of cold-hot water separating Device；It is environmentally friendly, ineffective mainly to solve the problems, such as that existing electric heater big energy-consuming is unfavorable for.

The technical solution of the utility model is：A kind of electric heater of cold-hot water separating, including staving, the top of staving are set Hot water outlet, lower part set cooling water inlet；It is characterized in that, the staving is vertical structure, in staving bottom set electricity plus Hot pin sets piston, piston and inner wall of barrel clearance fit in staving, is sealed by O-ring seal, piston is in staving in it Wall moves up and down；Piston spring is set between the interior bottom of the piston and staving；Interstitial hole is opened in the centre position of the piston, The bottom of interstitial hole sets thermostat valve, and adiabatic bullet is set in the middle part of interstitial hole, and adiabatic bullet moves up and down in interstitial hole, absolutely Bullet spring is set above hot bullet, bullet spring one end is connect with adiabatic bullet, the other end and piston interstitial hole Top edge connects；The intake pressure of the cooling water inlet is more than the pulling force that piston spring generates, the pulling force that piston spring generates The pressure generated more than adiabatic bullet.

Further, lower body two parts group made of piston upper body made of heat-insulating material and nonadiabatic material At.

Further, the interstitial hole of the upper body part of the piston is bell mouth shape wide at the top and narrow at the bottom, the lower body of piston Partial interstitial hole is cylindric.

Further, the interstitial hole clearance fit of the upper body part of the adiabatic bullet and piston.

Compared with the prior art a kind of electric heater of cold-hot water separating described in the utility model has following actively effect Fruit makes cold-hot water separating, hot and cold water is avoided directly to exchange using the devices such as thermostat valve and piston are installed in staving additional, and hot water can be with It fully uses, to reduce heat exchange, reduces energy consumption, improve the thermal efficiency.

Specific implementation mode：

For a better understanding and implementation, providing specific embodiment below in conjunction with the accompanying drawings is described in detail the utility model；Institute It is only used for explaining the utility model for embodiment, is not intended to limit the scope of the utility model.

Embodiment 1, referring to Fig. 1, according to design requirement, it is vertical structure to select suitable staving 8, staving 8, staving 8 Top has hot water outlet 9, lower part to have cooling water inlet 10, and electrically heated rod 7 is installed in bottom in staving 8, and electrically heated rod 7 passes through circuit It is connect with external power supply, piston 3 is installed in staving 8, piston 3 is made in upper body 11 and nonadiabatic material made of heat-insulating material 12 two parts of lower body composition, piston 3 and 8 inner wall clearance fit of staving, the two sealed by O-ring seal 4, and piston 3 is in bucket It is moved up and down along its inner wall in body 8；Interstitial hole is opened in the centre position of piston 3, the interstitial hole of 11 part of upper body of piston 3 is upper The interstitial hole of narrow bell mouth shape under width, 12 part of lower body of piston 3 is cylindric；Thermostat valve 5 is installed in the bottom of interstitial hole, Predetermined temperature is set in thermostat valve 5, the adiabatic bullet 2 of installation at the middle part of interstitial hole, adiabatic bullet 2 is wide at the top and narrow at the bottom Bullet, the interstitial hole clearance fit of 11 part of upper body of adiabatic bullet 2 and piston 3, adiabatic bullet 2 in interstitial hole on Lower movement, in 2 bullet spring 1 installed above of adiabatic bullet, 1 one end of bullet spring is connect with adiabatic bullet 2, another End is connect with the top edge of 3 interstitial hole of piston；Piston spring 6 is installed between piston 3 and the interior bottom of staving 8；Cooling water inlet 10 Intake pressure be more than the pulling force that piston spring 6 generates, the pulling force that piston spring 6 generates is more than the pressure that adiabatic bullet 2 generates Power；Form a kind of electric heater of cold-hot water separating of the utility model.

A kind of electric heater of cold-hot water separating of the utility model, operation principle：As the hot water of Fig. 1, water heater add After heat, cold water inlet valve is opened, when cold water enters water heater by the cooling water inlet of staving bottom, the staving of water heater is by piston It is divided into two chambers up and down, thermostat valve is closed since water temperature is low at this time, effect of the adiabatic bullet in bullet spring Under be also at closed state, at this time intake caused by pressure be more than piston spring pressure；Cold water pushes piston to move up, and opens Hot water effluent's valve, hot water are flowed out from the hot water outlet on top, and such as Fig. 2, after the hot water of staving epicoele all discharges, piston is pushed up To the top of water heater, upper intracavitary has a small amount of hot water at this time, lower intracavitary be into cold water, electrically heated rod start-up operation, instantly The cold water of intracavitary is heated to the temperature set by thermostat valve（Such as 60 degree）Afterwards, thermostat valve is opened, at this time epicoele and lower intracavitary Pressure is the same, and piston moves downward under piston spring pulling force；Since piston moves downward, adiabatic bullet is in taper at this time Under the effect of body spring, adiabatic bullet is pushed up, and such as Fig. 3, as piston moves downward, the hot water of lower intracavitary passes through thermostat valve With adiabatic bullet channel, epicoele is flowed to, epicoele becomes larger at this time, and cavity of resorption tapers into, at this time upper and lower two chambers unicom, water Warm consistent, when with hot water, with the entrance of cold water, cavity of resorption water temperature reduces, and thermostat valve is closed, and adiabatic bullet is in bullet bullet Under the action of spring, closing, such as Fig. 4 are also moved down, as hot water is constantly released, and is repeated the above process；Avoid hot and cold water direct It exchanges, hot water can be used fully.
