Abstract

The utility model relates to a household electric iron for ironing clothes, which is composed of a cover handle and an electrothermal bottom plate. The utility model is characterized in that the electrothermal bottom plate connected to the lower part of the cover handle is in a buried structure, the ironing surface of the bottom of the electrothermal bottom plate is smooth, and the upper part surface is provided with a slot through which an electrothermal element can be buried; the electrothermal element adopts heating cords or conductive ceramics. The heat storage capacity is large; the effect on ironing clothes is favorable; the energization and the temperature rising are fast; the insulation index is high; the power is saved; the service life is long.

Description

Electrical hand iron

The utility model relates to household electrical appliance, is a kind of electric iron of boiling hot Ironing thing concretely.

The present both at home and abroad electric iron of producing, mainly contain two kinds of forms with regard to the electric hot plate of its product bottom faces: outside upper side, an attached heating wire that is wrapped in mica sheet is formed by an iron plate for 1, external-heat common electrical flatiron, the electric hot plate of this form.Its shortcoming is that electrothermal efficiency is poor, service life short, damp attitude insulation index is low.2, internal heat type steam electric iron, this product is the production technology from external introduction, and electric hot plate is cast into electrothermal tube in aluminium sheet through extrusion process, and handle through polytetrafluoroethylene (PTFE) on the surface of electric hot plate.Its shortcoming is the production cost height, and this structure can not use the conductivity ceramics element as the electric iron electric heat source.

The purpose of this utility model is to provide a kind of electric heating base plate can use heating wire also can use the electric iron of conductivity ceramics element, improves electrothermal efficiency, the product that the life-span is long and cost is low.

The utility model is to realize like this, in the bottom of covering 1, it is smooth through a bottom dough made with boiling water of craftwork manufacture moulding such as die casting, founding with metal material that the plate shaped electric heating base plate 3 that connects is installed, upper side has the some grooves that can imbed heating 5 11 that communicate, these grooves 11 are through after the insulation processing, pack into heating heating wire or conductivity ceramics such as PC, PTC, DZR etc., or heating 5 is contained in the groove 11 after the porcelain bead insulation processing.Require groove 11 be communicate so that the coiling of heating 5 with connect.Its degree of depth is about 10mm, and width is in 20mm.Insulating powder 6 is inserted in space between heating 5 and the groove 11, with heatproof glue sealing compound 7 it is sealed again.Or the glass precursor solution of the injection of the space in groove 11 through heating, it is sealed.

The utility model has the following advantages with the like product ratio:

1, to store up capacity big for heat, scalds to press effectively, and quick heating is used in energising.

2, heating is to work under the state of oxygen barrier, thereby long service life, and insulation index height.

3, the non-metallic conducting material that can imbed good electrical property easily is as conductivity ceramics such as PC, PTC, DZR, and power savings is comparatively obvious, and this is the advantage that present any electric iron does not have.

Because class normal domestic use electric iron or high-grade technology electric iron during These characteristics, the utility model electric iron are fit to make very much.

Below in conjunction with accompanying drawing and enforcement the utility model is further specified.

Fig. 1 is a schematic diagram of the present utility model.

Among the figure 1, cover 2, plug 3, electric heating base plate 4, terminal

5, heating 6, insulating powder 7, sealing compound 8, nut

9, screw 10, thermosistor 11, base plate upper side groove

Fig. 2 is the cutaway view of electric rebasing plate.

Among the figure 3, electric heating base plate 4, terminal 5, heating 6, insulating powder 7, sealing compound 8, nut 11, base plate upper side groove

Accompanying drawing is embodiment of the present utility model.

The cover of this electric iron selects for use (1) art ceramics to make an animal shape, and its waist uses as handle.Cover connects an electric heating base plate (3) to the bottom of (1) by screw (9) with lower nuts (8), this electric heating base plate (3) is cylinder iron made, handle through enamel on the surface, bottom faces is smooth, it is about 15mm that upper side has width, elongate slots about degree of depth 10mm (11), shape and structure as shown in Figure 2, heating (5) adopts the PTC conductivity ceramics to make and groove (11) mouthful similar shapes, electric heating base plate (3) is after enameling process carries out insulation processing, heating (5) is presented in the groove (11), if heating (5) is long, can the section of being divided into manufacture, connect with wire then.

Require these grooves (11), the opening that can make heating (5) coiling should be arranged between groove and the groove, insulating powder (6) will be inserted in the space between groove (11) and the heating (5), uses sealing compound (7) that it is sealed then.Heating (5) is connected on the terminal (4) through metal wire or sheet metal string (also), is connected on the plug (2) through thermosistor (10) again.

When the present embodiment energising is used, because the existence of groove (11), heating (5) is encapsulated in again in the electric heating base plate (3), the electric weight of heating (5) is very fast like this looses to the bottom faces of electric heating base plate (3), electrothermal efficiency is very high, this structure heating (5) is realized rational distribution density easily, and the radiating surface of electric heating base plate (3) is that well-proportioned particularly this structure can adopt conductivity ceramics as heating (5), and its service life and economize on electricity meaning are bigger.The utility model embodiment cover combines the manufacturability of (1) with the advance of electric heating base plate (5), will be the good product of foreign exchange earning.

Claims

1, a kind of novel electric iron of boiling hot Ironing thing, it comprise cover 1, electric heating base plate 3, it is characterized in that electric heating base plate 3 of connection being installed in 1 bottom at cover, this electric heating base plate 3 is to make a bottom to press that face is smooth, upper side has the groove 11 that can imbed heating 5, these grooves are after insulation is handled, the heating 5 of packing into, or heating 5 packed into after the porcelain bead insulation processing in the groove 11, insert insulating powder 6 and with heatproof glue sealing compound 7 it is sealed again, or in groove 11, inject it is sealed through the glass precursor solution of heating.
