Abstract

The utility model provides a flat instantaneous water heating device and includes a metal cavity, the two ends of which have a water inlet and a water outlet, and a metal electrically heated film. The main body of the metal cavity is flat, and the height of the inner cavity is 1mm to 4mm; the metal electrically heated film is flaky and can be closely stuck to the surface of the upper and lower outer wall of the main body of the metal cavity. The metal electrically heated film can also be arranged in the inner cavity of the main body of the metal cavity and is parallel to the upper and lower outer wall. The utility model heat water when water is injected into the container, and reaches the needed temperature, thus the utility model is a flat instantaneous water heating device which has the advantages of energy saving, high heating efficiency, and easiness for carrying and installation.

Description

Flat type instant water heating device

Technical field:

The utility model relates to the water heating apparatus technical field, refers in particular to a kind of flat type instant water heating device.

Background technology:

Existing water heater adopts electrothermal tube more on the market, electrical bar or the pot body is heated with electromagnetic oven, in adding thermal effect, use electrothermal tube, electrical bar and electromagnetic oven heating can both reach the effect of water heating, but in time control, exist not enough, electrothermal tube, electrical bar and electromagnetic oven heating need be carried out water body and be stored before heating, carry out the water body heating within a certain period of time, when stored water with after can heat again, that is to say, when needs use hot water, can not accomplish that moment cold water advances hot water and goes out, and can not obtain enough and continuous waters.General instant electric water heater, electric consumption power quite consumes energy up to 7000 ~ 8000 watts.This type of water heater internal electrical hot pin adopts peromag MgO ₂As insulating barrier, exist the electric leakage risk, and volume is bigger, not portable, deposit, install.Its heating arrangement as shown in Figure 3, add hot-water cavity 01 and be the great circle cartridge type, a plurality of heating tubes 02 are established in inside, this kind structure, heating source and water body distance, the efficiency of heating surface is not high, reason is because the thermal conductivity factor of water is low than metal, and the distance between water body and the heating source directly influences the efficiency of heating surface, distance and the efficiency of heating surface relation of being inversely proportional to, distance is big more, and the efficiency of heating surface is low more.

Summary of the invention:

The purpose of this utility model is to improve used electrothermal tube in the past, the limitation of form such as electrical bar and electromagnetic oven heating on heat time heating time, providing a kind of can heat water when water injects this container, water when container flows out, reach required temperature energy-conservation, the efficiency of heating surface is high, the flat type instant water heating device that is easy to carry and installs.

For achieving the above object, the technical scheme that the utility model provides is: comprise that two ends have the metallic cavity and the metal electric heating film of water inlet, delivery port, the main body 4 of metallic cavity is a flat, and the height of inner chamber is 1～4mm; The metal electric heating film is laminar.

Described metal electric heating film has two kinds of installation forms: a kind ofly be that it is close to the surface of outer wall up and down of the main body of metallic cavity.When water injects in the main body of metallic cavity from water inlet, water is by the main body of flat metallic cavity, the metal electric heating film heats at the outer wall of metallic cavity, because flat design, pyrotoxin is dwindled greatly with the distance that contacts of water, make the water body of the metallic cavity of flowing through be heated fully, then outer wall is transmitted to heat in the water fast, water fully contacts with last lower wall in the inside of flat metallic cavity main body, utilize the good heat conductivity of metal, when water when the canister delivery port flows out, water temperature has reached necessary requirement.Another kind is that it is located at embedded with metal electric heating film between the main body inner wall of metallic cavity, and when flowing water enters main body from water inlet, in flat body interior, the metal electric heating film directly heats current, to reach the effect to the water heating.

Advantage of the present utility model is: 1, have good heating property, the metal electric heating film has characteristics such as electrothermal calefactive rate is fast, and thermal inertia is little, and heating surface (area) (HS is big.2, select for use metals such as copper, stainless steel to do cavity, heat-transfer effect is good, and photoelectric transformation efficiency height, electric consumption power are compared with existing product less than 3000 watts, and power consumption significantly reduces.3, unique flat design in the flowing water passageway of chamber body has reduced the distance between heating source and the water body, has increased the contact area with metallic walls, makes water body well accept the heat that the metal electric heating film produces.4, whole device volume is less carries easily, installs and deposit.

The specific embodiment:

Embodiment 1:

As shown in Figure 1, present embodiment has the metallic cavity and the metal electric heating film 3 of water inlet 1, delivery port 2 by two ends, and the main body 4 of metallic cavity is a flat, and the height design of inner chamber is generally 2mm, and metal electric heating film 3 is laminar.Metal electric heating film 3 is close to the surface of outer wall up and down of the main body 4 of metallic cavity.

The operation principle of present embodiment sees also shown in Figure 1: flowing water enters from water inlet 1, when passing through the front end of cavity, the scatter flat stream hydrospace of the main body 4 that enters metallic cavity of the water body that enters, metal electric heating film 3 heating powers, heat is transmitted in the water, because the cross section in flowing water space is extremely flat, highly be 2mm, flowing water is contacted fully with heating surface, reaches fully to add thermal effect, flows out from delivery port at last.

Embodiment 2:

As shown in Figure 2, present embodiment has the metallic cavity and the metal electric heating film 3 of water inlet 1, delivery port 2 by two ends, and the main body 4 of metallic cavity is a flat, and the height design of inner chamber is generally 4mm, and metal electric heating film 3 is laminar.Metal electric heating film 3 is embedded in the inner chamber of the main body 4 of metallic cavity, and is parallel to inwall up and down.

The operation principle of present embodiment sees also Fig. 2, flowing water enters from water inlet 1, when passing through the front end of cavity, the scatter flat stream hydrospace of the main body 4 that enters metallic cavity of the water body that enters, be embedded in the De Absolutely Edge metal electric heating film 3 energising work of flowing water space, directly current are heated because the metal electric heating film directly heats flowing water, so current to add thermal effect better.

In sum, the utility model is the form that adopts a metallic cavity to combine with metal electric heating membrane, and water is carried out Fast Heating, reaches the temperature effect of demand.Being to use the high power Electric radiant Heating Film in suitable areal extent current to be heated, is by long test, the achievement that accurate Calculation obtains.The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
