Abstract
The invention discloses an instant electric water heater. The instant electric water heater comprises heating units and is formed by connecting and combining the multiple heating units. Each heating unit comprises an upper base, a lower base and a film heating sheet clamped between the two bases. A water inlet is formed in each upper base, and a water outlet is formed in each lower base. The adjacent heating units are connected through the water inlets and the water outlets. A thermistor is arranged on each film heating sheet to be connected with a control circuit of the electric water heater. According to the electric water heater, the film heating sheets are used as heating elements of the heating units, the film heating sheets are high in heating efficiency, fluid flowing into gaps between the film heating sheets and sealing rings is heated, the water flow heating area is increased, and the heating efficiency is effectively improved; as the thermistors are additionally arranged to serve as temperature control elements, the stability of the temperature of output water is easily improved; the heating units can be flexibly combined and applied, the structure is simple and reliable, and safety is high.

Background technology
Be utilize the heating tube installed therein to carry out heating during electric water heater heating, the inside of heating tube is heating wire, can generate heat after energising.Existing electric heater, in order to improve the efficiency of heating surface, is typically provided with a high-power electro-heat equipment, when water by time just it is heated, because power is very large, observable index is higher, complex structure, and the security of this type of electric heater is also usually under suspicion.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of instant electric water heater with preventing dry combustion function, adopt the heating unit tiling arrangement of laminated structure as water flow heater, the efficiency of heating surface is high.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of instant electric water heater, comprise heating unit, this electric heater is combined by the connection of several heating units, the film heating sheets that described heating unit comprises upper bed-plate, lower bottom base and is clipped between two bases, described upper bed-plate is provided with water inlet, described lower bottom base is provided with delivery port, be connected with delivery port by water inlet between adjacent heating unit, described film heating sheets is provided with thermistor and is connected with the control circuit of electric heater, for controlling heating-up temperature and having preventing dry combustion function.
Preferably, be provided with sealing ring between described film heating sheets and base, described sealing ring is frame-shaped rubber ring.
Preferably, described film heating sheets is the soft lamellar body be sticked to form by the nickel alloy electricity backing with insulating barrier, and the extension of its edge is provided with positive and negative electrode connector.
Above-mentioned thermistor is negative temperature coefficient thermistor, and thermistor, to responsive to temperature, shows different resistance values at different temperature, and this negative temperature coefficient thermistor (NTC) resistance value when temperature is higher is lower.
Embodiment one, described heating unit is arranged in U-shaped structure.
Embodiment two, described heating unit is arranged in loop configuration.
Preferably, described heating unit is provided with ground lead.
Beneficial effect of the present invention: this electric heater adopts film heating sheets as the heating element heater of heating unit, film heating sheets heating efficiency is high, the fluid in the space flowed between film heating sheets and sealing ring is heated, the heating surface area of current is strengthened, effective raising efficiency of heating surface, increase thermistor as temperature control element, be conducive to the stability improving output water temperature, prevent the empty burning situation of electric heater from occurring; In addition, heating unit can flexible combination be applied, and simple and reliable for structure, security is high.
Detailed description of the invention
With reference to Fig. 1-4, a kind of instant electric water heater provided by the invention, comprise heating unit 1, this electric heater is combined by the connection of several heating units 1, described heating unit 1 comprises upper bed-plate, lower bottom base and the film heating sheets 2 be clipped between two bases, described upper bed-plate is provided with water inlet, described lower bottom base is provided with delivery port, (accompanying drawing the structure of not shown upper bed-plate and lower bottom base) is connected with delivery port by water inlet between adjacent heating unit 1, described film heating sheets 2 is provided with thermistor 4 and is connected with the control circuit of electric heater, this control circuit is IC circuit, namely the resistance value that thermistor 4 exports is read by IC circuit.
In this embodiment, the concrete thermistor 4 adopted is negative temperature coefficient thermistor (NTC), the resistance of this NTC reduces with the rising of temperature, Real-Time Monitoring water temperature during work, when heating-up temperature reaches electric heater design temperature, NTC feedback signal, to control circuit, controls power output by control circuit and makes temperature reach constant.
In addition, design NTC can prevent electric heater from occurring empty situation of burning, specifically, this NTC is fitted on the electric heating piece in film heating sheets 2, and at the width design comparatively thin (accompanying drawing this concrete structure not shown) of the position electric heating piece of NTC laminating, now the resistance of this section of electric heating piece is higher, can show hotter during energising, thus play a protective role, its principle be current by film heating sheet 2 time, film heating sheets 2 heats up slower in water in the unit interval; But if there is when cutting off the water supply, it is very fast that film heating sheets 2 exposes the interior intensification of unit interval in atmosphere, now judges empty burning occurs according to the temperature variations of NTC, thus carry out power down process immediately; Further, whether design power cut off delay 5-10 conducts electricity after second again, detect empty burning situation and removed, normally work to recover electric heater.
Preferably, be provided with sealing ring 3 between film heating sheets 2 and base, sealing ring 3 is frame-shaped rubber ring, forms a cavity between film heating sheets 2 and sealing ring 3, and current are contacted with film heating sheets 2, and heating surface area strengthens, thus improves the efficiency of heating surface; The film heating sheets 2 adopted in embodiment is the soft lamellar body be sticked to form by the nickel alloy electricity backing with insulating barrier, and the extension of its edge is provided with positive and negative electrode connector 5.In order to improve the safety in utilization of electric heater, heating unit 1 arranges ground lead.
Arrange number and the arrangement architecture of heating unit 1 according to the heating capacity demand of water heater, its arrangement architecture can adopt and be connected in series or syndeton that connection in series-parallel combines, embodiment one, and heating unit 1 is arranged in U-shaped structure; Embodiment two, heating unit 1 is arranged in loop configuration, and shown in Fig. 3 and Fig. 4, combination simple and flexible, Stability Analysis of Structures is reliable.During work, current heat through several heating units 1 successively, and because current and fever tablet contact area are comparatively large, film heating sheet 2 one energising can heat generation hot water, and heating highly effective and safe, volume structure also reduces greatly.
The above, just preferred embodiment of the present invention, in the present invention, the arrangement architecture of heating unit 1 is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
