Description

Convenient electric cooking utensils

The utility model relates to the family expenses electric cooking appliance, electric cooking appliance especially easy to use.

Electric cooking appliances such as electric teapot, electric cooker, electric food warmer, relatively simple for structure, generally by housing, electric heater, the power supply coupling arrangement perhaps has a sleeving temperature controller concurrently and combines.The characteristics of electric cooking appliance are that electrical power is big.Existing current techique adopts card edge type with power contact head in use, and the contact that is about to plug directly is inserted in the contact of socket, has following shortcoming: 1. and good in order to contact, must firmly be seated, must be very firmly when extracting, it is very inconvenient to use; 2. in order to extract conveniently, often contact slack and undisciplined badly during insertion, cause contact resistance to increase, not only want many power consumptions, and element is damaged because of overheated.

At above-mentioned shortcoming, the purpose of this utility model provides a kind of both laborsaving, power saving, can guarantee to contact good electric cooking appliance again.

Feature of the present utility model is to utilize one week of screw thread rotation, therefore only displacement one pitch can the labour-saving principle, the card edge type of power supply connecting mode from prior art is improved to being threaded into formula, promptly screw in the external screw thread of socket on the electric cooking appliance base with the internal thread annulus on the attaching plug, make plug connect energising with the contact of socket, so both laborsaving, power savings guarantee that again contact is good.

The utility model is compared with existing electric cooking appliance: other structure is constant, power supply coupling part material and cost increase are seldom, its outstanding advantage is to use conveniently, not only laborsaving but also contact good, especially suitable woman,child,the old and the young, both can avoid many power consumptions, not fragile again element has social benefit and economic benefit.

Below in conjunction with the accompanying drawing introduction.

Accompanying drawing is partial schematic sectional view of the present utility model and profile schematic diagram.(1) is the electric cooking appliance housing; (2) be the electric cooking appliance socket base, on external screw thread is arranged; (3) be the electric cooking appliance receptacle connector; (4) be the electric cooking appliance header contact; (5) be the plug base; (6) be the internal thread annulus, it can rotate around the plug base, but does not have axial displacement between the two.

During use, with header contact (4) alignment socket contact (3), simultaneously internal thread annulus (6) is inserted on the external screw thread of base (2), rotating ring (6), plug (5) is promptly made axial advance to socket (2), whenever rotate a circle, push ahead a pitch, until header contact (4) contacts well with receptacle connector (3) till.When finishing using, deenergization, opposite spin internal thread annulus (6), contact (3) promptly disengages with contact (4), and is both convenient, laborsaving again.

For existing electric cooking appliance, can adopt following two kinds of methods with the direct insertion screw-in that changes at least: 1. transposing socket; 2. do not remove old socket, just installing one on old socket additional has externally threaded socket, and one is inserted in the old socket, and there is external screw thread the other end, and it is matched with internal thread annulus (6).

Identical in the material of the coupling arrangement of power supply described in the utility model and the prior art, its size and size determine by purposes (as electric teapot, electric cooker, electric food warmer etc.) and watt level.

Power supply connecting mode of the present utility model can also be applicable in the bigger electrical equipment of other power.

Claims (2)

1, a kind of electric cooking appliance easy to use; Electric cooking appliance is generally by housing, heater, power supply coupling arrangement or have sleeving temperature controller etc. concurrently and constitute, and the socket of electric cooking appliance housing base that is characterised in that of the present utility model is made up of contact and external screw thread etc., and plug is made up of contact and internal thread garden ring etc.; Utilize internal thread garden ring to screw in and make two contacts contact energising in the external screw thread.

2,, it is characterized in that installing one additional in existing electric cooking appliance has externally threaded socket according to the described electric cooking appliance easy to use of claim 1; One is inserted in the old socket; There is external screw thread the other end, it is encircled with the internal thread garden on the plug match.
