Description

Water control type micro-electric heating hydrophone

The utility model relates to the electric heater technical field.Particularly a kind of micro-electric heating hydrophone that is connected to tap.

Cold season, both cold with washing thing from the beginning, do not wash clean greasy dirt again, it is very inconvenient to heat up water with cooker, therefore people press for a kind of miniature hot-water device that can be directly installed on the tap, directly to the running water Fast Heating, can scrub thing with hot water easily and safely.There is following shortcoming in the past tap electric heater of design: (1) does not have the water control function, closes tap, still continues the empty burning of energising, wastes energy, and burns out easily.Must pull out power supply earlier, after turn off the tap operation inconvenience.(2) earth leakage protective imperfection is generally only taked grounding measures by force, even some makes the earth leakage circuit-breaker tripping operation after the ground connection by force.(3) can not directly link to each other with family's tap, must increase connector, install inconvenient.(4) no tap water filter function.

The purpose of this utility model is to overcome above-mentioned deficiency, designs a kind of micro-electric heating hydrophone, and the work water control type is simple to operation; Directly link to each other with tap easily, easy for installation; Reliable earth leakage protective measure is arranged, safe in utilization.

The purpose of this utility model is achieved by the following technical solution: water control type micro-electric heating hydrophone, directly be loaded on the tap, constitute by plastic base, cylinder electrode, U-shaped electrode, metal shower nozzle, rubber seal pipe, special feature is that inner chamber is equipped with temperature relay, temperature relay one termination cylinder electrode, another termination power firestreak; U-shaped electrode connecting to neutral line.Further, cylinder electrode is nested in the U-shaped electrode, and U-shaped electrode outer surface is with the plastic insulation cover, forms tank with the plastics urceolus.

Below in conjunction with drawings and Examples the utility model is further elaborated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an electrical schematic diagram of the present utility model.

Embodiment:

As shown in Figure 1, water control type micro-electric heating hydrophone is made up of plastic base 1, cylinder electrode 2, U-shaped electrode 3, plastic insulation cover 4, temperature relay 5, plastics urceolus 6, metal shower nozzle 7, rubber seal pipe 8 and stainless steel screen pack 9.Water hole is opened at pedestal 1 center, and the upper end is the cassette joint, and water inlet is equipped with stainless steel screen pack 9, links to each other with tap by rubber seal pipe 8, utilizes the elasticity of plastics, with screw 11 lockings.

Cylinder electrode 2, U-shaped electrode 3 are on screw thread fixed plastics pedestal 1.Cylinder electrode 2 is nested in the U-shaped electrode 3, and central shaft overlaps, and at a distance of certain interval, cylinder electrode connects power firestreak by temperature relay 5, and U-shaped electrode 3 connects zero-power line (can reversal connection), and U-shaped electrode 3 sidewalls are left water hole 14.Because the water conduction, just by Fast Heating, the tap of fetching boiling water just had hot water to flow out continuously when water flow through between cylinder electrode 2, U-shaped electrode 3.Control relative area and gap between cylinder electrode 2 and the U-shaped electrode 3, just can control the power of water heater.Regulate the water heater water yield, just can regulate water temperature.

Plastic insulation cover 4 is a U-shaped, be fixed on the pedestal 1, be enclosed within U-shaped electrode 3 outsides, be used for water power isolation and plastics urceolus 6 formation tanks 10, the water that comes out from U-shaped electrode 3 flows to tank 10 by the sidewall apopore 14 of plastic insulation cover, flow in the metal shower nozzle 7 of ground connection from tank 10 again, guarantee that delivery port and power firestreak have bigger distance, increase the resistance of water, reduce leakage current, guarantee safety.Metal shower nozzle 7 double as water heater delivery ports catch electrical network and plastics urceolus 6 is threaded, and by three core power line ground connection and connect metallic water pipe (multiple grounding), make earth leakage protective.The hole that shower nozzle 7 bores about 30 1mm reasonably is distributed on inside and outside two annulus, increases water-outlet area.

Temperature relay 5 is used for realizing the water heater working water control type, and the one end is fixed on the cylinder electrode 2, guarantees to be electrically connected, and the other end connects live wire with lead, and exposed metal part guarantees that temperature relay 5 disconnects, cylinder electrode 2 outages with the glue sealing.Its metal temperature-sensitive partly is immersed in the heated water.The tap of fetching boiling water, during the water heater operate as normal, water temperature is not high, and temperature relay is failure to actuate; Close tap, residual low amounts of water is heated rapidly, and water temperature raises rapidly, and 3 seconds internal cutting off power supplys of temperature relay stop heating, and relay indicating light 13 goes out.The tap of fetching boiling water again, the cold water that flows through is lowered the temperature temperature relay rapidly, connects power supply in 3 seconds again, water heater working, relay indicating light 13 is bright, and this has just realized the water heater working water control type.Electrical principle as shown in Figure 2.Temperature relay 5 connects power firestreak through protective tube 12, and neon bulb indicator lamp 13 is with in parallel with the equivalent resistance R of water heater again after current-limiting resistance R1 connects.

In sum, little (Φ 36 * 80mm), and is simple in structure, easy to manufacture, and production cost is low, cheap for the utility model water heater volume; Be not afraid of empty the burning, can be because of abnormal operation does not damage, the life-span is long; Be easy to directly link to each other with water tap, easy for installation; The work water control type has indicator lamp to show, and is simple to operation; Reliable earth leakage protective measure is arranged, safe in utilization; Can clean filtration, one-object-many-purposes to running water.Can be widely used in places such as resident family, factories and miness, school, hotel, barber shop, directly to running water heating, it is cold with washing thing from the beginning to have solved cold season, does not wash clean greasy fouling problem again.
