Abstract
The utility model relates to an instant-heating electric boiler which comprises a boiler body, wherein, a water inlet and a water outlet are arranged on the boiler body; an electric heat body is arranged inside the boiler body. The utility model is characterized in that the boiler body is made from insulating materials; a restricted channel which is separated by a plurality of staggered spoilers and consists of an inflow layer, an insulating layer, a heating layer, an insulating layer and an outflow layer is arranged from the water inlet to the water outlet inside the boiler body; an electric heat body directly contacting the water is arranged on the center of the heating layer; the space between spoilers of the two insulating layers is smaller than that of the spoilers among the inflow layer, the heating layer and the outflow layer. The flow rate is slow in the heating layer and quick in the two insulating layers, thereby the electric heat body is smooth in heat dissipation and transmission, and the thermal efficiency is improved; because the flow of current flow is lengthened through the spoilers arranged between the two insulating layers, so the water resistance is increased and the leakage current is reduced, in accordance with the safety requirements of the human body.
Description
Technical field
The utility model relates to a kind of instant heating type electric boiler.Belong to the electrical heating type hot-water boiler.
Background technology
At present two types electric boiler is arranged in this technical field.A kind of is heat storage electric boiler, it is to place electric heating element in the water tank of filled with water, water in the water tank is heated under immobilising state, could from water tank, flow out use after the heating, because water tank is filled with water more, at short notice water being heated needs to consume a large amount of electric energy, and the non-uniform temperature of water, and top often heat is following cool; Another kind is an instant heating type electric boiler, and current are heated through electrothermal tube or Electric radiant Heating Film, is commonly called as " crossing hydro-thermal ", and firing rate is fast, and temperature is even.Two kinds of electric boilers are compared, and instant heating type electric boiler is because simple in structure, and firing rate is fast, and even water temperature does not need water storage, and is in light weight, and occupies remarkable advantages.
In the transient heating electric boiler, because the processing technology complexity of Electric radiant Heating Film, compound film quality is difficult to guarantee, adopts electrothermal tube to take advantage as calandria.The weak point of instant heating type electric boiler was in the past: the inflow segment of boiler, bringing-up section, the flow velocity that flows out Duan Shui is identical, can not fully absorb heat at bringing-up section water, heated water is because flow velocity is identical with the water velocity of front and back, also some heated water can not in time flow away, and is continued heating, influences result of use.The heating tube that adopts resistance wire and magnesia to make filler contact heating and directly contact with water to heat with resistance wire and compare with water, the employing resistance wire directly contacts with water, and the thermal efficiency obviously improves.Adopt the resistance wire heating will well solve leakage problem, must guarantee safe in utilization.
Summary of the invention
The purpose of this utility model provides and a kind of electric heating element is directly contacted with water, by the choked flow passage that in the insulation body of heater, is provided with, control the water velocity of the electric heating element of flowing through, help the heat radiation and the heat transfer of electric heating element, and the flow process by water before and after the lengthening electric heating element increases water resistance, make leakage current little, instant heating type electric boiler safe in utilization.
The purpose of this utility model is achieved in that instant heating type electric boiler, it comprises body of heater 1, on body of heater 1, be provided with water inlet 2 and delivery port 4, be built-in with electric heating element 3 at body of heater 1, its special character is: body of heater 1 is insulating materials body of heater 1, the inflow layer 6 that 4 settings are separated by several spoilers 5 that are staggered from water inlet 2 to delivery port in insulating materials body of heater 1, insulating barrier 7, zone of heating 8, insulating barrier 9, outflow layer 10 a choked flow passage of forming are at the electric heating body 3 that the center that is positioned at zone of heating 8 is provided with and water directly contacts.The spacing of the spoiler 5 of the gap ratio inflow layer 6 of the spoiler 5 of said insulating barrier 7,9, zone of heating 8, outflow layer 10 is narrow.Said insulating materials body of heater 1 is interconnected by each the single-unit body of heater 11,12,13,14,15 with inflow layer 6, insulating barrier 7, zone of heating 8, insulating barrier 9, outflow layer 10 respectively to be formed.Said electric heating element 3 or adhere to the insulated synthetic resin layer.
Instant heating type electric boiler of the present utility model owing to make body of heater with insulating materials, is installed electric heating element in the insulation body of heater, make it and the water Direct Contact Heating of the body of heater of flowing through; Owing in the insulation body of heater, be provided with the choked flow passage that several spoilers that are staggered are formed, and it is narrow that the spoiler gap ratio that makes two insulating barriers flows into the spoiler spacing of layer, zone of heating, outflow layer, thereby make the flow velocity of water in two insulating barriers fast, the flow velocity of the water in the residing zone of heating of electric heating element is slow, help the heat radiation and the heat transfer of electric heating element, and no longer heating has been heated into the water of uniform temperature, and makes its direct discharge.Therefore, when improving the efficiency of heating surface, reduce power consumption again; Because spoiler makes the current flow process lengthening of two insulating barriers of flowing through, strengthened the water resistance of this one, the leakage current of electric heating element is reduced to below the safety index, guarantee safe in utilization.
