Abstract

An instant electric water heater comprises a housing, a cylinder block inside the housing, a relief valve, an electric heating tube and a temperature controller, which is characterized in that an adjusting knob is fixed with a rotating bar of a power adjusting device so as to adjust various power, and the electric heating tube with various power is sealed inside the cylinder block with small volume which is sealed and is without leakage of water, and further the electric heating tube is a spiral tube inside which a heating wire coated with an insulating layer of magnesium oxide is arranged, and the on and off of the electric heating tube is controlled by a micro switch on the power adjusting device. The instant electric water heater discharges hot water 10 seconds after starting, which is convenient and rapid and not only saves time but also greatly reduces space and complexity in process production.

Description

The instant electric water heater

The utility model relates to a kind of instantaneous water heater, particularly relates to a kind of instant electric water heater.

The volume of the various water storage liner of existing storage-type electric water heater is usually greater than 30---60L, and not only take, and need wait during shower, or use in turn successively than large space, extremely inconvenient, lose time again.

The objective of the invention is to overcome the above-mentioned deficiency of prior art, provide a kind of volume little, quick and convenient, simple and compact for structure instant electric water heater.

The utility model is on the basis of the electric heater of the temperature controller that prevents dry combustion method that earth leakage protective device is arranged; adopt the different electric heating tube of custom-designed several power; and be encapsulated in the inner bag of little volume---in the cylinder body; the volume of this cylinder body is about 4% of common storage-type electric water heater inner bag---and 7%; and the microswitch on the utilization PCU Power Conditioning Unit relevant with discharge starts corresponding heating tube; promptly this device be one with microswitch that every heating tube is electrically connected on contact portion be subjected to the structure of discharge control; the technical assurance in discharge hour; make wherein one or two heating tube conducting heating (the microswitch conducting that is in series); all conducting heating when the water yield is big are to reach the flow that needs temperature.Above-mentioned electric heating tube is the resistance heating wire who has the magnesia insulating barrier to contain in the helix tube.

Cylinder body volume of the present utility model about 1.2-4.2L, usually water flowing start the back about 10 second instant-heating and outlet hot, convenient and swift, both saved time, significantly reduce the complexity in space and the explained hereafter again.

Further specify the utility model below in conjunction with accompanying drawing.

This reality is novel shell 14 and interior inner bag or cylinder body 4 thereof, relief valve 15, electric heating tube 1 and temperature controller 5, and by the indicator lamp 11 on the shell 14 and power adjusting knob 12 its duties of demonstration and selection adjusting water temperature, it is characterized in that adjusting knob 12 is fixing to regulate different capacity with the swing arm 9 of PCU Power Conditioning Unit 6, promptly regulate water temperature by the power adjusting knob, the different electric heating tube 1 of power is encapsulated in the heating cylinder body 4 of the watertight little volume of driving fit, and electric heating tube 1 and microswitch 10 are electrically connected and accept microswitch 10 controls on the PCU Power Conditioning Unit 6 and be switched on or cut off.The volume of the cylinder body 4 of containing electric heating tube 1 is in the 1.2-4.2 scope.

Above-mentioned electric heating tube 1 is the heater strip 3 that has magnesia insulating barrier 2 to contain in the helix tube, isolates to realize water power.There is binding post at electrothermal tube 1 two ends, connect an end N and the microswitch 10 of power supply respectively, link to each other with power supply other end L through temperature controller 5, generally are connected in the circuit via the external terminal S on line and the shell 14, and electric heating tube 1 selects the 2-3 root to be advisable usually.It among the figure example that 2 electric heating tubes are arranged.

Above-mentioned PCU Power Conditioning Unit 6 is the box-like cavitys 7 of a circle that communicates with water inlet pipe, but this cavity top has and is subjected to influent pressure control and has with the circle of the band convex-concave structure body of the contact D interlock of microswitch 10 to touch plate 8, as Fig. 4, Q, R represent convexconcave part respectively, this shake-up plate 8 is regulated by the swing arm 9 of tabling and is set the on off operating mode of microswitch, and this shake-ups plate 8 is subjected to snap ring 11 that its below links and touches cap 12 and keep off dropping fraction 13 and brake.Above-mentioned retaining dropping fraction 13 is rubber gaskets, and the porose discoid snap ring 11 in center fits with touch panel 8 and limits and touch cap moving about in the of 12.

Obviously the utility model compact conformation volume is little, energy-efficient quick and convenient, is the new type ideal water heater.
