Description

The electric hot water warmer

The electric hot water warmer that the utility model relates to is a kind of electric heating equipment.

Existing family electric heating equipment, also useful open oven silk electric heating is promptly dangerous except air-conditioning, electric furnace heating wire directly contacts with air, oxidation easily, service life is short, the oil immersion space heater, the cost height, it is slow to heat up, and can not regulate indoor humidity, can not use hot water, can not shower, the insulation degree is poor.

The purpose of this utility model is to overcome above-mentioned disadvantage, and providing a kind of is that medium carries out electrical heating with water, and heating source does not directly contact with water, with the electric hot water warmer of the absolute insulation of radiator.

In order to achieve the above object, the utility model is to realize like this, it has binding post 1, power switch 2, heating rod 3, return pipe 6, filler pipe 7, fin 8, water inlet pipe 9, water tank 10, venthole 11, filler 14 is characterized in the heating rod 3 outer porcelain tubes 4 that are with, be with double-deck cartridge heater 5 outside the porcelain tube 4, open a hole and water inlet pipe 9 one ends join on the lateral wall of the upper end of double-deck cartridge heater 5, the cavity of double-deck cartridge heater 5 communicates with the cavity of water inlet pipe 9, opens a hole on the lateral wall of the lower end of double-deck cartridge heater 5, join with return pipe 6 one ends, the cavity of double-deck cartridge heater 5 communicates with the cavity of return pipe 6.When 14 topped up with water from the filler, binding post 1 connects the 220V power supply by power switch 2, turning on the power switch 2 electrical heating wires that electric current is passed through on the heating rod 3 heats, heat radiation on the heating rod 3 is given porcelain tube 4, the heat radiation of porcelain tube 4 is given double-deck cartridge heater 5, the heat of double-deck cartridge heater 5 is passed to the water in the double-deck cartridge heater, heat progressively by heating rod 3 that to carry out with water be the thermal cycle of medium, hot water enters fin 8 through water inlet pipe 9, again in return pipe 6 returns double-deck cartridge heater 5, form circulation, make indoor progressively intensification.

The utility model is simple in structure, be provided with rationally, heating rod and fin and other connector definitely insulate, can establish a threeway connector at water inlet pipe, a termination faucet, a termination shower nozzle, and be provided with venthole, sewage draining exit, but indoor humidity blowdown again can be regulated, and the utility model is present a kind of more satisfactory electric hot water warmer.

Description of drawings:

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

Fig. 2 is the structural representation that heating rod, porcelain tube, double-deck cartridge heater are installed together.

The explanation of accompanying drawing drawing:

1 binding post, 2 power switches, 3 heating rods, 4 porcelain tubes, 5 double-deck cartridge heaters, 6 return pipes, 7 filler pipes, 8 fin, 9 water inlet pipes, 10 water tanks, 11 ventholes, 12 supply sockets, 13 sewage draining exits, 14 filler, 15 circular panels.

In order to understand better and to implement, it is as follows with the accompanying drawing to be that example further specifies below: heating rod 3 can adopt the effective heater strip of the porcelain insulating of Φ 20mm to be wound in 800W, long 600mm, fill insulating packing in the porcelain insulating pipe, binding post 1 adopts three of the red copper screw rods of M5 to bond together with insulating cement and porcelain insulating pipe, the heater strip two ends are fixed on the binding post 1 with copper nut, another binding post earth connection, porcelain tube 4 adopts Φ 36mm, heating rod 3 is sleeved in the porcelain tube 4, pipe Φ 38mm in double-deck cartridge heater 5 adopts, the stainless steel cylinder of outer tube Φ 51mm is welded, lateral wall is opened the circular hole of Φ 21mm up and down, double-deck cartridge heater 5 is enclosed within outside the porcelain tube 4, adopt the tube and pipe of aluminium alloy of external diameter Φ 36mm, the wing that dispels the heat is in addition done water inlet pipe 9, return pipe 6, connect with the circular hole up and down of double-deck cartridge heater by work in copper respectively and be connected, fin 8 adopts aluminum alloy materials, height is 600mm, wide is 100mm, thick 30mm, with water inlet pipe 9, return pipe 6 joins, inner chamber communicates, fin 8 adopts 4 or 5 and gets final product, and the other end of water inlet pipe 9 is by a stainless steel threeway connector, and last termination one stainless steel bend is made venthole 11, in order to make full use of the utilization rate of electric hot water warmer, can connect a stainless steel threeway connector at the following end connector of stainless steel threeway connector, a termination faucet, another section connects shower nozzle, can connect and use hot water, but shower again.Filler pipe 7 adopts the stainless steel tube of Φ 25mm, and a sewage draining exit 13 is established in the lower end, and the lower end joins by a threeway connector and return pipe 6, and inner chamber communicates, and threeway connector lower end blocks sewage draining exit 13 by a plug, during the need blowdown, plug is turned on get final product blowdown.Filler pipe 7 upper ends and water tank 10 join, and water tank 10 adopts the stainless steel cylinder of Φ 51mm to make, and two ends is made plug with the cylinder welding with stainless steel material, and filler 14 is opened in the upper end.Directly be not with on the electric hot water warmer in order to make power plug wire, can establish a supply socket 12, for power switch 2 and supply socket 12 are fixed on the electric hot water warmer, an if circular panel 15, circular panel 15 adopts identical with water tank 10 materials, specification, interior edge pastes an insulation board, supply socket 12, power switch 2 are installed on the circular panel 15, by power supply wiring binding post 1, power switch 2, supply socket 12 are connected, circular panel 15 is fixed together with an end of water tank 10, seem promptly attractive in appearance, harmony again.For easy to use, can be the power line that the electric hot water warmer is equipped with a two ends band plug, use as need, two plugs are got final product with external power supply and supply socket 12 connections respectively, for conveniently moving, also can be equipped with two universal wheels, as want to hang use in electric hot water warmer lower end, fix two hooks on the wall, the electric hot water warmer is hung up get final product.
