CN2225826Y - Double temp. controlled type multipurpose electric rice pot - Google Patents

Abstract

The utility model relates to a double temperature controlled type multipurpose electric rice pot which adds a temperature control timing circuit on the basis of the double tube energy saving multipurpose electric rice pot. The temperature control timing circuit is composed of a thermoswitch K5 and a timer electric motor which are connected in series, wherein, the K5 is a normally open thermoswitch and closes only when the temperature reaches 98 DEG C. The utility model is provided with double heating tube, uses the arts of temperature control timing and temperature control power transformation, realizes the automation of boiling rice, porridge and soups, increases the accuracy and the operational reliability of cooking and boiling timing and is easily controlled and operated.

Description

Two Temperature Control Types are used electric cooker more

The utility model relates to a kind of family expenses electric cooker that boils, and particularly one has that temperature control is regularly boiled, two Temperature Control Types of power transfer function are used electric cooker more.

Having in the technology now, popular electric cooker function singleness, be only limited to the control automatically of cooking, and cook congee, boil soup, very important persons such as fricassee guard, use inconvenient, computer-shape electric cooker multiple functional, but complex structure costs an arm and a leg, and it is limited to popularize face, the patent " two-tube energy-saving multi-purpose electric cooker " that the inventor proposes, the patent No. 92242282.6, on the basis of popular electric cooker, improve becomes the electric cookers of using that have timing and automatic transform power to boil more, for people provide a kind of multifunctional product of high quality and at a reasonable price, but it is to pick up counting when beginning to heat and since be subjected to pot amount what, temperature, the influence of factors such as voltage height, its bad timing is true, the quality that influence is boiled.

The purpose of this utility model provides a kind of improved pair of Temperature Control Type and uses electric cooker more, has adopted the temperature control timing technology, and accurately boiling time in control pot adapts to people and uses needs.

The purpose of this utility model is to realize by following measure: the straight-through contact of this electric cooker timer connects thermoswitch, main heat-generating pipe and pays heat-generating pipe, thermoswitch is connected the timer timing contact with the other end of paying heat-generating pipe, the other end of main heat-generating pipe connects temperature limiter and warmer, time motor and thermoswitch are composed in series the temperature control timing circuit, and the temperature control timing circuit connects another contact of timer.It is the shelves of cooking that timer is connected straight-through contact, directly main heat-generating pipe heating is given in power supply, behind the cooked, temperature limiter is jumped the insulation of pulling, it is the shelves of cooking congee that timer is connected timing contact, electric current is supplied with main heat-generating pipe heating through thermoswitch, the thermoswitch of connecting with time motor is an off state, and motor does not move, and temperature reaches about 97 ℃ in pot courage, be connected the thermoswitch automatic disconnection between straight-through contact and timing contact, electric current flows into main heat-generating pipe through paying a heat-generating pipe because series resistance increases, conversion heating power, when temperature reaches about 97 ℃ in pot courage, the thermoswitch of connecting with time motor is connected automatically, the motor timing that brings into operation, up to timing to point, timer disconnects power supply, and boiling finishes.

Concrete structure of the present utility model and embodiment are drawn by the following drawings:

Fig. 1 is that two Temperature Control Types are used the electric cooker circuit structure diagram more.

The utility model is described in further detail below with reference to accompanying drawing: the structure of this electric cooker has pot body, pot courage, pot lid, heat-generating disc, with reference to Fig. 1, and timer K ₁Straight-through contact A ₁Connect thermoswitch K ₂, pay heat-generating pipe R ₂, K ₂And R ₁The other end connect K ₁Timing contact B ₁, the other end of main heat-generating pipe connects temperature limiter K ₄, the temperature control timing circuit is by thermoswitch K ₅M is composed in series with time motor, timer K ₁Timing contact B ₂Connect motor M.Thermoswitch K ₂Be normally closed thermoswitch, after temperature reached 98 ℃, automatic disconnection made main, pair heat-generating pipe series connection, the conversion heating power; Thermoswitch K ₅Be often to drive thermoswitch, when temperature reached 98 ℃, auto-closing made and decides device operation timing.

The utility model is provided with two heat-generating pipes, adopts temperature control timing and temperature control transform power technology, realizes cooking, cook congee, boil the soup automation, improved the accuracy, the functional reliability height that regularly boil, multiple functional, operation control is to be suitable for to popularize wide sky kitchenware easily.

Claims (2)

1, a kind of pair of Temperature Control Type used electric cooker more, pot body, pot courage, pot lid, heat-generating disc, timer arranged, timer K ₁Straight-through contact A ₁Connect thermoswitch K ₂, pay heat-generating pipe R ₁, main heat-generating pipe R ₂, K ₂And R ₁The other end connect K ₁Timing contact B ₁, the other end of main heat-generating pipe connects temperature limiter K ₃, warmer K ₄, it is characterized in that being provided with the temperature control timing circuit, the temperature control timing circuit is by thermoswitch K ₅M is composed in series with time motor, timer K ₁Timing contact B ₂Connect the temperature control timing circuit.

2, electric cooker according to claim 1 is characterized in that thermoswitch K ₅Be often to drive thermoswitch, after temperature reaches 98 ℃, auto-closing.
