Abstract

The utility model provides an instant electric water heater. The instant electric water heater at least comprises an inner liner, a water inlet opening and a water outlet opening which are formed on the inner liner and an electric heating pipe arranged in the inner liner, wherein a copper pipe spirally rising to the top of the inner liner from the bottom of the inner liner is evenly installed in the inner liner and around the electric heating pipe and bends downwards from the top of the inner liner to form a straight pipe leading to the bottom of the inner liner, a spiral copper pipe positioned at the bottom of the inner liner is connected with a water inlet pipe, and the cold water enters from the copper pipe, is preheated through a long copper pipe with length of 2 m to absorb the heat around the walls of a vessel, then is heated through a heater and then flows out from a water outlet opening of the vessel. Therefore, the heat exchange time is prolonged, the heat around the wall of the heating pipe is sufficiently absorbed to ensure that the temperature of the water outlet opening is higher than that of the wall of the heating pipe, the social energy is saved, the internal loss of heat can be reduced due to the sufficient absorption of the copper pipe to heat of the wall of the heating pipe, the service life of the instant electric water heater is prolonged, and the securityis enhanced.

Description

Quick-heating electric water heater

Technical field

The utility model relates to the electric heater technical field, particularly a kind of quick-heating electric water heater.

Background technology

Along with growth in the living standard, electric heater also more and more spreads to ordinary family, storage-type electric water heater adopts electric heater for heating at present, need to set needed water temperature before use, when water temperature reaches when presetting water temperature, the power supply of the attemperating unit automatic disconnection electric heater of electric heater, stop the heating, there are problems such as hot water, the installation volume that can not provide abundant in the long and short time of heat time heating time are excessive, energy consumption is big in the storage-type electric water heater of this structure and heating mode; Though the instant electric water heater can provide hot water fast, but cold water comes in to heat 2-3 after second from container bottom, go out from container top, heat exchanger time is short, and cold water does not fully absorb heat and just goes out from the container overhead stream, especially cold water is than great, flow velocity is fast, and the heat around the heater wall is not fully absorbed, and not only wastes energy but also make the element utensil aging easily, influence the life-span of water heater, the multiple factor of increase accident.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of enhancing to add the quick-heating electric water heater of thermal effect, minimizing energy consumption.

The purpose of this utility model is finished by following technical solution, a kind of quick-heating electric water heater, at least comprise inner bag, be arranged on water inlet and delivery port on the inner bag, be arranged on the electric heating tube in the inner bag, in the described inner bag, around electric heating tube, be equipped with one uniformly and rise to the copper pipe at inner bag top from inner bag bottom spiral, this copper pipe is bent into a straight tube downwards and leads to the inner bag bottom again from the inner bag top.

Described copper pipe is bent into a straight tube and leads to the inner bag bottom along inner bag center line or inner bag edge.

Described water inlet joins with the helical form copper pipe that is positioned at the inner bag bottom, and cold water enters from this copper pipe, through being about the pre-heat absorption heating tube of the long copper pipe wall heat of 2m; Described delivery port is positioned at the inner bag top, and flow out from this delivery port heating tube heating back, can guarantee that the delivery port temperature is higher than the temperature that heats tube wall.

The utility model is by installing spiralling copper pipe around electric heater, make the cold water that enters pass through warm and heating process, prolonged heat exchanger time, the temperature of heating tube wall fully can be absorbed, minimizing is to the water heater diffusion inside, guaranteed that the delivery port temperature is higher than the temperature that heats tube wall, pass through contrast test, at inflow temperature, flow velocity, under the identical condition of volume, as leaving water temperature also is transferred to unanimity, the utility model can energy-conservation 15%--20%, and the power that the water heater of a 6.8KW produces is equivalent to the power of 8KW water heater in the market, has saved the social energy.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done detailed introduction: a kind of quick-heating electric water heater, at least comprise inner bag 1, be arranged on water inlet 2 and delivery port 3 on the inner bag 1, be arranged on the electric heating tube 4 in the inner bag 1, in the described inner bag 1, around electric heating tube 4, be equipped with one uniformly and rise to the copper pipe 5 at inner bag 1 top from inner bag 1 bottom spiral, this copper pipe 5 is bent into straight tube 5 downwards from inner bag 1 top and leads to inner bag 1 bottom again.

Described copper pipe 5 is bent into a straight tube 5 and leads to inner bag 1 bottom along inner bag 1 center line or inner bag 1 edge.

Described water inlet 2 joins with the helical form copper pipe 5 that is positioned at inner bag 1 bottom, and cold water enters from this copper pipe 5, the long copper pipe 5 pre-heat absorption heating tube 4 wall heats through being about 2m; Described delivery port 3 is positioned at inner bag 1 top, and the water of preheating flows out from this delivery port 3 after heating tube 4 heating.

Described copper pipe 5 diameters are Φ 6 * 0.5cm, the about 2m of length, cold water enters spiralling copper pipe 5 from water inlet 2, behind the long copper pipe 5 pre-heat absorption heating tube wall heats of 2m, spiralling copper pipe 5 fully absorbs the heat of heating tube 4 walls, carry out sufficient heat exchange with the water in the copper pipe 5, water in 4 pairs of inner bags of heating tube 1 further heats simultaneously, after heating tube 4 heating, flow out from inner bag 1 top, can guarantee that like this delivery port 3 temperature are higher than the temperature of heating tube 4 walls, the diameter of copper pipe 5 and length can redesign according to the demand to hot water in the real life, can save the social energy again like this when producing a large amount of hot water, the abundant absorption of 5 pairs of heating tubes of copper pipe, 4 wall heats can reduce the internal loss of heat, prolong the service life of quick-heating electric water heater, strengthened security.
