Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Be below embodiment:

The utility model embodiment provides a kind of light radiation electric heater, as shown in Figure 2, Figure 3, Figure 4, comprises spirality water pipe 1, luminous radiation heating pipe 3, heater jacket 2.Described spirality water pipe 1 is provided with helix tube water inlet 12, helix tube delivery port 11; described luminous radiation heating pipe 3 is located in the cavity that spirality water pipe 1 is coiled into; be provided with heater jacket 2 outside described screw type water pipe 1, between described luminous radiation heating pipe 3 and spirality water pipe 1, be provided with position limitation protection buckle 33.Its outer heater jacket 2 be arranged with, can better fix spirality water pipe 1, makes that it is not yielding, outward appearance is more attractive in appearance, and plays certain heat insulation effect.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, existing Instant heating type metal heater heat-generating pipe is due to the restriction in space, the length limited of the heating tube of metal heater, its heat-generating pipe tube wall 61 thermic load is very large, easy generation incrustation scale, due to scaling, the heat energy of metal tube heaters well can not be dispersed into from its heat-generating pipe tube wall 61 and be gone by the water that heats, easily like this cause the temperature in metal heater heat-generating pipe too high, and cause damage.The spirality water pipe 1 that the utility model adopts, because it is screw type coiling, same volume size, its length can reach 3 times of existing Instant heating type metal heater or more, significantly can reduce the thermic load of spirality water pipe 1 tube wall, effectively reduce the factor that incrustation scale produces.Existing Instant heating type metal heater shell 6 communicates with its heat-generating pipe tube wall 61 electric conductivity, when leaky appears in heat-generating pipe tube wall 61, metal tube heaters shell 6 will be caused or the current that contact with heat-generating pipe tube wall 61 charged.The utility model luminous radiation heating pipe 3 does not directly contact with screw type water pipe 1, light radiation electric heater is used safer.

As shown in Figure 5, in order to obtain the larger heating power of single group light radiation electric heater, in the cavity that spirality water pipe 1 is coiled into, the luminous radiation heating pipe 3 of more than two or two can be set.In order to make single group light radiation electric heater under high power work state, heat exchange effect is better, in the cavity that spirality water pipe 1 is coiled into, be provided with a center heating pipe 7, its center heating pipe 7 is placed in the centre of combined light radiation heating tube 3, described center heating pipe's water inlet end 72 is connected with heating water inlet 42, and heating pipe water side, center 71 is connected with helix tube water inlet 12, better can give heated water by the thermal energy conduction between luminous radiation heating pipe 3.In order to prevent luminous radiation heating pipe 3 from colliding with peripheral spirality water pipe 1 or center heating pipe 7, cause luminous radiation heating pipe 3 cloche to damage, luminous radiation heating pipe 3 is provided with position limitation protection buckle 33.

The utility model can be that two groups or more light radiation electric heater series and parallel is combined, and can meet the user demand of more high-power or different voltage and electric current.

As shown in Figure 2, Figure 3, Figure 4, the coiling of described spirality water pipe 1 is closely affixed, and can guarantee the heat energy sent luminous radiation heating pipe 3, assimilation effect is better.

As shown in Figure 6, Figure 7, described heating water inlet 42, add hot water outlet 41 and be fixed on light radiation electric heater drain pan 4, flow sensor 52 is located in heating water inlet 42, and temperature sensor 51 is located at and is added in hot water outlet 41.The electrode terminal 31,32 of flow sensor 52, temperature sensor 51, luminous radiation heating pipe 3 and control panel 5 electrically connect.The current at supply equipment or water source enter from heating water inlet 42, through flow sensor 52, helix tube water inlet 12, enter in spirality water pipe 1, spirality water pipe 1 absorbs the heat energy sent from luminous radiation heating pipe 3, flow out from helix tube delivery port 11, through temperature sensor 51 to adding hot water outlet 41 to water equipment.When current are through flow sensor 52, flow sensor 52 is by the Signal transmissions that senses to control panel 5, and the signal that control panel 5 is collected from the flow sensor 52 received, controls luminous radiation heating pipe 3 and work, realize sensing flux, the effect that heating controls automatically.The described hot water outlet 41 that adds is provided with temperature sensor 51, temperature sensor 51 can sense the temperature of spirality water pipe 1 water outlet, be transferred to control panel 5, thus the power realizing the heating of control panel 5 pairs of luminous radiation heating pipes 3 controls, reach spirality light radiation electric heater, output temperature regulates automatically.

Connecting line 54 on the electrode terminal 31,32 of described luminous radiation heating pipe 3 is high temperature resistant wire rod, can guarantee luminous radiation heating pipe 3 pass to heat on its electrode terminal 31,32, damage can not be caused to electrode terminal 31,32 connecting line 54.Described helix tube water inlet 12, helix tube delivery port 11 are traveling nut, can easily with heating water inlet 42 and add hot water outlet 41 carry out installation and removal.

The utility model is due to structural safety, and heating effect is good, and cost is low, safeguards simple feature, not only can be used for heating water, can also be widely used in heated air, heating wet goods field.

Above a kind of spirality light radiation electric heater that the utility model embodiment provides is described in detail, the explanation of above embodiment is just for helping the core concept understanding principle of the present utility model, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
