Abstract
The utility model relates to a water heater having a heat generating device, particularly a heater with separate continuously flowing water and heating media. A miniature safety fast electric water heater is composed of a box body, heating elements, a control element, a connecting element and a water spray head. The heating elements adopt a bowl-shaped phase wire electrode and a bowl-shaped zero wire electrode, the control element is arranged in the box of the water heater, and water flow switch is arranged between the phase wire electrode and the zero wire electrode. The utility model has the advantages of high safety, reasonable structure, easy use, etc. The utility model is an ideal electric water heater for families and similar application.
Description
The utility model includes the water heater of heat-generating device, especially continuous-flow, that water and heat medium are separated from each other heater.
Water heater existing continuous-flow, that water and heat medium are separated from each other has two big classes, and a class is a gas heater, and another kind of is electric heater.Electric heater exists the relatively poor disadvantage of security.
The electric heater that provides a kind of security better, rational in infrastructure, easy to use is provided the purpose of the utility model.
Miniature electric heater safely and fast is made up of insulation casing and dress heat generating member, control piece, connector and fountain head thereon.In the insulation casing water channel is arranged.Connector comprises the locking nut with insulated case body and function thread connection, is contained in filter screen, seal washer and retainer plate between insulation casing and the locking nut.Heat generating member is bowl-type phase line electrode and bowl-type zero wire electrode, and control piece is contained in the electric appliance box, between phase line and the zero wire electrode water flow switch is housed.
Below in conjunction with embodiment shown in the drawings, the utility model is done detailed explanation.
Attached Fig. 1 and 2 is the utility model front view and takes vertical view behind the case lid apart, and accompanying drawing 3 to 6 is A-A, B-B, C-C and D-D profile, and accompanying drawing 7 is the utility model electrical schematic diagrams.
Shown in accompanying drawing 1 to 7, miniature electric heater safely and fast is made up of insulation casing 10 and dress heat generating member, control piece, connector and fountain head 3 thereon.In the insulation casing 10 water channel 9 is arranged.Connector comprises the locking nut 11 with insulation casing 10 usefulness thread connection, is contained in filter screen 13, seal washer 12 and the retainer plate 14 that is connected with water supply pipe or valve between insulate casing 10 and the locking nut 11.Heat generating member is a pair of bowl-type metal electrode, and top is bowl-type phase line electrode 6, and the bottom is a bowl-type zero wire electrode 5, and certainly, electrode also can be other analogous shapes.Form pipeline between the electrode, continuous-flow running water in the pipeline, and be heated.There is the inlet opening at the middle part of phase line electrode 6, is communicated with water channel 9.The periphery of zero wire electrode 5 has several apopores, and hot water flows out from apopore, sprays water outlet through fountain head 3.Several water spray apertures are arranged on the fountain head 3.Control piece is contained in the electric appliance box 4 of insulation.Electric appliance box 4 is positioned at the upper left side of insulation casing 10.The case lid of electric appliance box 4 is fixed on the insulation casing 10 with housing screw.Zero line is connected on the zero wire electrode binding post 17, connecting resistance R and the wiring of relay K A normally opened contact on the phase line electrode terminal 18.Between phase line and the zero wire electrode 5 water flow switch 8 is housed.Phase line is through fuse FU, button SB
1, SB
2Behind the coil of relay K A, be connected on the upper terminal of water flow switch 8.On the lower terminal of zero wire electrode 5 water receivings stream switch 8, this terminal passes phase line electrode 6 and water channel 9, between phase line electrode 6 and zero wire electrode 5 insulating washer 7 is housed.Water flow switch 8 is answered the water conductivity principle, and when running water was flowed through water channel 9, water flow switch 8 was connected, the work of bowl-type electrode pair; When not having tap water flows water channel 9, water flow switch 8 disconnects, and the bowl-type electrode pair is not worked.
Shown in accompanying drawing 1,2 and 7, control piece comprises button (SB
1, SB
2), relay (KA) and indicator lamp (HL
1, HL
2).Start button 15 (SB
2), stop button 16 (SB
1) and relay indicating light (HL
1), power supply indicator (HL
2) be contained on the wall of electric appliance box 4, relay K A, fuse FU, diode V and resistance R are contained in the electric appliance box 4.
As shown in Figure 7, power indicating circuit is equipped with protection diode V.The anodal phase-connecting wire of this diode V, negative pole connecting to neutral line.Bowl-type phase line electrode 6 and bowl-type zero wire electrode 5 are connected on respectively on phase line and the zero line.If power supply wiring is correct, power supply indicator 2 (HL
2) just can be bright, otherwise to change phase line and zero line, thus guarantee that zero wire electrode 5 is connected on the zero line all the time, hot water flows out from zero wire electrode 5 all the time, thereby guarantees safety.
The course of work of the present utility model is summarized as follows: connect power supply, indicator lamp HL
2Bright; Open running water valve, water flow switch 8 is connected, and has produced the current load resistance between the electrode pair; Press start button SB this moment
2, relay K A gets electric, relay indicating light HL
1Bright, electrode pair work, hot water promptly can continuously outflow.If press stop button SB
1, perhaps close running water valve, relay indicating light HL
2Can extinguish, the electrode pair outage stops heating at once.
Obviously, because the utility model is provided with bowl-type electrode 5,6, water flow switch 8, electric appliance box 4 add the unique circuit design, thereby security performance is enhanced.Add the configuration design novelty, rational in infrastructure, easy to use, be the desired electrical water heater of family expenses and similar applications.
In the embodiment shown in the figures, appearance and size of the present utility model is φ 65 * 58.
