Abstract
The utility model relates to a household appliance, particularly an energy-saving electric water heater, composed of a water inlet, a water pipe, a water outlet, a heater, a controller and a safe earthing device. The utility model is characterized in that the heater comprises a casing, an insulating plate and heating elements, and the inner lining of the casing is provided with a heat-resistant insulating plate matched with the casing; the center of the inner lining of an insulating arc and the heater are respectively provided with a metal heating element which is provided with a zero line end leading out a leading wire to be connected with power supply and a fire line end, and a water flowing passage is arranged between the heating elements. The utility model has the advantages of small size, light weight, little occupied space and no needed water storage tank, and does not have to be preheated and can save energy.
Description
The utility model relates to a kind of household electrical appliance, specifically a kind of energy-saving electric water heater.
In the prior art, domestic, electric water heater partly is made up of modulator, heater, storage tank, water inlet pipe and water outlet pipe etc., its shortcoming is: during work, the electrothermal tube that must connect in the heater earlier carries out preheating, water in the heating storage tank uses, storage tank is heavy, area occupied is big, and preheating time is long, is difficult to accurately estimate water consumption.
The purpose of utility model be to avoid above-mentioned shortcoming of the prior art and provide that a kind of volume is light and handy, heat supply water energy-saving electric water heater rapidly.
In order to achieve the above object, the utility model provides a kind of new technical solution: its heater is made up of shell, insulation board and heating element heater, shell is positioned at the outside of heater, its underpart links to each other with water inlet, the top water receiving pipe is lined with the heat-resistant insulating board that matches with it in the shell, be respectively equipped with metallic heating element at the center of insulation board liner and heater, heating element heater is drawn zero line and the live wire end that lead is access to power supply respectively, is provided with the flowing water passage between heating element heater.
Compared with prior art, the utlity model has following advantage: volume is little, and is in light weight, and it is little to take up space, must storage tank, must preheating, and can heat water outlet, save the energy.
Accompanying drawing is embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model.
Be described in further detail below in conjunction with the essentiality content of drawings and Examples the utility model energy-saving electric water heater.
As shown in the figure; this device mainly is made up of heater (1), modulator (9) and safety grounding device (7); modulator (9) comprises that electric leakage protector, stepless power adjuster, voltmeter, ammeter, power meter, switch and transfer wire etc. partly form; be between power supply and the heater (1), be used for observation, adjusting and protection the water heater operation conditions.Safety grounding device (7) is positioned at the end of water pipe (6), and its effect is further to improve safety coefficient.Heater (1) is the electro-heat equipment of whole water heater, its underpart links to each other with water inlet (5), top water receiving pipe (6), heater (1) is made up of shell (2), insulation board (3) and heating element heater (4), shell (2) is rectangular flat structure, make with thick plastic plate, insulation board (3) is made with the high-temperature insulation plastic material, center along insulation board (3) liner and heater (1) is respectively equipped with the heating element heater (4) that stainless steel material is made, and heating element heater (4) is drawn lead and linked to each other with the zero line and the live wire end of power supply respectively.Itself has resistance water, and the resistance value of water is 1300 ohm/cubic centimetre, adds electrode therein, and water can be heated in the extremely short time, and swiftly flowing current can be in 1～2 second, and about 10 centimetres flow process is brought up to more than 70 ℃ by normal temperature.After water enters heater (1) from water inlet (5), connect power supply, water is heated between heater (1), and from heater core (1) back water temperature reaches about 70 ℃, crosses safety grounding device (7) through water pipe (6) and discharges from delivery port (8), confesses hot water.Regulate modulator (9) and valve and carry out water temperature and Flow-rate adjustment.The appearance and size of present embodiment is 300mm * 210mm * 55mm, electrical heating power: 0～4KW, water flow: 1.6～4.0L/min, weight: 2kg.After testing, the thermal efficiency can reach 87%, is higher than the thermal efficiency of storage-type electric water heater 82%.
Claims (1)
1. energy-saving electric water heater, it is mainly by water inlet, water pipe, delivery port, heater, modulator and safety grounding device are formed, modulator is by electric leakage protector, the stepless power adjuster, voltmeter, ammeter, power meter, switch and transfer wire etc. are partly formed, it is characterized in that: heater (1) is by shell (2), insulation board (3) and heating element heater (4) are formed, shell (2) is positioned at the outside of heater (1), its underpart links to each other with water inlet (5), top water receiving pipe (6), the heat-resistant insulating board (3) that shell (2) liner matches with it, center at insulation board (3) liner and heater (1) is respectively equipped with metallic heating element (4), draw zero line and the live wire end that lead is access to power supply respectively from heating element heater (4), between heating element heater (4), be provided with the flowing water passage.
