Abstract

The utility model relates to an electric heating device, belonging to a device for supplying the heat or the water by using the electric energy. The utility model comprises a casing which is provided with one water inlet and at least one water outlet. A heating wire arranged in a heating pipe is installed in the casing. Two ends of the heating wire extend to the outer part of the casing along the heating pipe. The utility model has the advantages of small size, low cost, high speed of warming, less power consumption, capable of maintaining the room temperature and wide range of application.

Description

Electric heating device

The utility model is a kind of electric heater, belongs to a kind of device that utilizes electric heat supply or water supply.

The device that is used for heat supply and water supply at present has many kinds, and wherein major part is to utilize coal stove heat supply or water supply, and consequent flue dust has caused great influence to the health in room.And that electrification is the hot-water heating system or the heating system function of the energy is also very single, maybe can only supply water, or can only heat supply, and the cost height, power consumption is big.

The purpose of this utility model is: design a kind of cost electric heater low, applied widely.

The utility model comprises the shell that has a water inlet and at least one delivery port, and the heating wire that places heating tube is installed in the shell, and the two ends of heating wire extend to the outside of shell along heating tube.The utility model was wanted by water inlet water to be injected shell inner cavity earlier before using, connect power supply then, the water around the heat that heating wire produces passes to by heating tube is flowed out by delivery port through adding hot water, the user can select one or several delivery port as required for use, is used for bathing, heating etc.Wherein, the two ends of heating wire join with two binding posts that are fixed on the shell outside, and by the ceramic blanket insulation, binding post has a separate terminal enclosure and shell to be connected outward between two binding posts and the shell, and power line is connected on the binding post.And the heating tube two ends will be connected with shell, and two binding posts are separately fixed in the two-port of heating tube, and ceramic blanket is between binding post and heating tube inwall.But, also should adorn a safety valve on the shell wall of the present utility model for preventing maloperation or former thereby cause the outer excessive rupture of case that causes of chamber pressure because of other.When the utility model was used to warm oneself, it only needed a water inlet and a delivery port, and being used for bathing then preferably has two delivery ports.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a phantom of the present utility model;

User mode figure when Fig. 2 is used to warm oneself for the utility model;

User mode figure when Fig. 3 is used for bathing for the utility model;

Wherein, 1-housing, 2-peace power valve, 3-heating tube, 4-sealing ring, 5-cap, 5-separate terminal enclosure, 6-power line, 7-binding post, 8-ceramic blanket, 10-sealing gasket, 11-heating wire.

As shown in Figure 1, the utility model is made up of shell, safety valve 2, heating tube 3, separate terminal enclosure 6, power line 7, heating wire 11.Wherein, shell comprises the housing 1 and the cap 5 of an end opening, has water inlet and delivery port on the housing 1, and safety valve 2 is installed on the wall of housing 1.The openend of housing 1 has the sealing ring 4 of a waterproof by cap 5 sealings between them.Two holes are arranged on the cap 5, and the heating tube 3 that is positioned at housing 1 passes this two hole respectively through bending its two ends, and respectively has a nut sealing gasket 10 to be fixed on the outside of cap 5 on its outer wall.Respectively be fixed with a binding post 8 in two ports of heating tube 3, the ceramic blanket 9 of insulation is arranged between its inwall and the binding post 8, be connected to power line 7 on the binding post 8.Heating wire 11 two ends that are installed in the heating tube 3 respectively link to each other with binding post 8.Separate terminal enclosure 6 is installed in outside the binding post 8 and by screw and shell and joins.

The utility model is installed between water inlet pipe and the shower nozzle as shown in Figure 2, just can be used for bathing.At this moment the utility model has a water inlet and two delivery ports, one of them is used and shower, another is used for bath in a tub, is preferably in the cold pipeline that has a valve of installing between the delivery port of water inlet pipe and bath in a tub as required, to regulate the temperature of bath in a tub water easily.

As shown in Figure 3, when the utility model is used to warm oneself, only need a water inlet and a delivery port, flow out water of the present utility model through behind the fin, enter the utility model by water inlet again and form recirculated water through heating.

Compared with prior art, the utlity model has that volume is little, cost is low, programming rate is fast, little power consumption, can keep indoor temperature and advantage applied widely.
