Abstract

The utility model relates to a steam-electricity converter for household high-pressure cookers, comprising a pressure cooker valve core and a voltage limiting weight dropper. A steam-voltage converting device composed of a wire, a power plug, a barrel lid, a barrel shell and a net is arranged outside the voltage limiting weight dropper. The inner part of the barrel shell is provided with two static contact pieces and one moving contact piece. Both poles of the wire are respectively connected with the two static contact pieces. The power plug is connected in a circuit composed of the coil and two frequently closed contacts of an intermediate relay. When the voltage limiting weight dropper is lifted by the internal steam pressure in the pot and deflates, the moving contact piece are pushed to contact the two static contact pieces and the auxiliary relay is switched on, realizing gas electrical signal conversion propitiously.

Description

Family expenses pressure cooker gas-electric converter

The utility model relates to the gas-electric converter of family expenses pressure cooker, particularly a kind ofly can realize automatic control for the family expenses pressure cooker and uses the gas-electric converter that facilitates.

Existing family expenses pressure cooker must use manually-operated, boils certain duration and degree of heating and when exitting when stewing, must be little thermal transfer by the people, and the pressure limiting weight is kept like playing non-state a to regular hour closed fire again, thereby stew the time of boiling weak point and energy-conservation, automatic operation but this just is far from being.Though and electric cooker and micro-wave oven can be realized automatic operation, boil because of under normal atmospheric pressure, stewing, so there is not pressure cooker quick, is difficult in the short time that food is stewed (boiling) and rots.Existing pressure switch and pneumatic-to-current converter are used for realizing sequence of movement or safeguard protection more; its something in common is air pressure signal to be introduced their air inlet; the air inlet opposite side can be moved by air pressure or revolving member on add adjustable initial tension of spring; when atmospheric pressure reaches the setting value of pretightning force; action with member disconnects or Closing Switch, sends the signal of telecommunication.The manufacturing of this class device and use are comparatively complicated, so should not be used for transmitting or changing the air pressure signal of family expenses pressure cooker.

The purpose of this utility model is that a kind of family expenses pressure cooker gas-electric converter will be provided, and the air pressure signal when it can be exitted the family expenses pressure cooker is converted to the signal of telecommunication.

For achieving the above object, the technical solution adopted in the utility model is: family expenses pressure cooker gas-electric converter of the present utility model, comprise pressure cooker valve inside, pressure limiting weight, outside the pressure limiting weight, be provided with an air pressure conversion equipment of forming by lead, attaching plug, cover, barrel shell, guard.Wherein cover and barrel shell are insulator, and both use thread connection, barrel shell and guard thread connection, and cover is provided with air-vent; Guard is made up of Shang Quan, following circle and the some vertical rods that are distributed between enclosing up and down, and last circle is provided with internal thread; The inner chamber of barrel shell is provided with two-stage step up and down, topping bar is provided with two static contacts, and they are installed in the lower surface at insulating trip two ends, and static contact and insulating trip are provided with air-vent, the position corresponding with two static contacts of getting out of a predicament or an embarrassing situation is provided with a movable contact spring, and it is installed in the upper surface of an insulating trip; The two poles of the earth of lead connect two static contacts respectively.Described attaching plug is connected in the circuit of being made up of two normally closed interlocks of the coil of auxiliary reclay and it and normally open contact; Normally closed interlock series connection back is in parallel with normally open contact, connects with coil again; Be provided with supply socket between two normally closed interlocks, the attaching plug series connection thereon.Cover and barrel shell are the transparent body.

The utlity model has following advantage: 1. utilized the required operating air pressure of family expenses pressure cooker single, and the characteristics of pressure limiting weight own wt and venthole pressure limiting, overflow, so omitted the pretightning force adjustable member of transmission air pressure; 2. when being lifted venting owing to the pressure limiting weight by the pot internal gas pressure, promote two static contact (distances between movable contact spring and pressure limiting weight of movable contact spring contact, can regulate by the threaded engagement of barrel shell and guard), so can realize the pneumatic-electric signal conversion smoothly after the auxiliary reclay energising; 3. provide convenience for realization pressure cooker temperature, time control,, then only need, and make it to cooperate, just can realize that the automatic control of pressure cooker is used with electric heat source at the external temperature of the set circuit of the utility model, time control circuit if pressure cooker adopts electric heat source.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is the structural representation of the utility model embodiment;

Accompanying drawing 2 is the utility model embodiment pneumat-electrical conversion circuit figure.

The family expenses pressure cooker gas-electric converter of accompanying drawing 1 illustrated embodiment comprises pressure cooker valve inside 13, pressure limiting weight 11, is provided with an air pressure conversion equipment of being made up of lead 1, attaching plug 2, cover 3, barrel shell 6, guard 15 outside pressure limiting weight 11; Wherein said cover 3 and barrel shell 6 are transparent insulator, and both use thread connection, barrel shell 6 and guard 15 thread connection, and cover 3 is provided with air-vent 17; Described guard 15 by last circle 9, down enclose 14 and the some vertical rods 10 that are distributed in up and down between the circle form, on enclose 9 and be provided with internal thread; The inner chamber of described barrel shell 6 is provided with two-stage step up and down, top bar and be provided with two static contacts 4, they are installed in the lower surface at insulating trip 5 two ends, static contact 4 and insulating trip 5 are provided with air-vent 16, the position corresponding with two static contacts 4 of getting out of a predicament or an embarrassing situation is provided with a movable contact spring 7, and it is installed in the upper surface of an insulating trip 8; The two poles of the earth of described lead 1 connect two static contacts 4 respectively; Described attaching plug 2 is connected in the pneumat-electrical conversion circuit of being made up of two normally closed interlocks of the coil of auxiliary reclay and it and normally open contact.When pressure limiting weight 11 is lifted venting by the pot internal gas pressure, promote two static contacts 4 of movable contact spring 7 contacts.

The pneumat-electrical conversion circuit of the utility model embodiment shown in the accompanying drawing 2 is made up of coil 22 and 19,20 and normally open contacts 21 of its two normally closed interlocks of an auxiliary reclay; Normally closed interlock 19,20 series connection backs are in parallel with normally open contact 21, connect with coil 22 again; Be provided with supply socket 18 between two normally closed interlocks, 2 series connections of attaching plug shown in the accompanying drawing 1 thereon.When two static contacts 4 of 7 contacts of movable contact spring shown in the accompanying drawing 1, coil 22 energisings of auxiliary reclay, when two normally closed interlocks 19,20 disconnected, normally open contact 21 closures just can be sent the signal of telecommunication, realized the pneumatic-electric signal conversion.If pressure cooker adopts electric heat source, then only need, and make it to cooperate with electric heat source at the external warm time control circuit of the utility model pneumat-electrical conversion circuit, just can realize that the automatic control of pressure cooker is used.
