Description

Energy-saving type electric cooker circuit

Technical field

The utility model relates to a kind of energy-saving type electric cooker circuit that can reduce the outside energy loss.

Background technology

At present, known mechanical type electric cooker its main heating circuit in the process of cooking is in "on" position always, and dry up to interior pot moisture content, just tripping of magnet steel entered keeping warm mode when interior pot bottom temperature rose to the magnet steel curie point, promptly main heating circuit outage.In this process, the heat that is sent by heat-generating disc partly is extraneous loss, part is that the heat considerable part that interior pot absorbs is given rice to be cooked by conduction, and the rice to be cooked in the interior pot can be divided into water and other food in addition that dewaters, wherein water absorbs heat always and saves heat to its boiling point before boiling, reach boiling point after, because of water in boiling process, its temperature remains unchanged, so the heat of redundance is taken away by steam.So after the water boiling, the heat part that heat-generating disc sends is fallen by steam loss, part continues by other food absorption beyond dewatering.At this moment, promptly after the water boiling,, and keep food and boil the process energy needed, promptly reach and to boil the waste that food again can fine control energy if can control the heat that steam is taken away.

Technology contents

The purpose of this utility model provides a kind of energy-saving type electric cooker circuit, need only add a thermostat and three auxiliary elements in current electric cooker circuit, can boil food at short notice, can reduce the loss of being taken away energy by extraneous steam again.

The utility model is made up of thermostat, selector switch, resistance, indicator lamp, and on former main heating circuit, an end is connected into a normally closed type thermostat K ₀, at normally closed type thermostat K ₀Two ends respectively and link a selector switch K ₁And and link a string branch, series branch is by resistance R ₀Series connection indicator lamp LAMP ₁Form, all the other circuits remain unchanged.Normally closed type thermostat K ₀Be contained in the aluminium lid end face.

The utility model is reasonable in design, and is simple in structure, under equal conditions, saves energy and can reach about 17% at least, and boil food fast, and the indicator lamp of cooking need only bright twice was edible after 6 minutes.

Description of drawings

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

The specific embodiment

In the utility model, connect normally closed type thermostat K by circuit shown in Figure 1 ₀The temperature spot that disconnects is 70 ℃ ± 2 ℃-100 ℃ ± 2 ℃, and the reset temperature point is 55 ℃ ± 5 ℃-95 ℃ ± 5 ℃.Normally closed type thermostat K ₀Must tightly put the high-temperature insulation cover in two electrode tips, after be contained in the aluminium lid end face, and make its working face and last aluminium lid contact area big as far as possible and be close to.For food being boiled fast and fully to the utilization of energy, normally closed type thermostat K ₀The temperature spot that disconnects is preferably got 95 ℃ ± 2 ℃, and reset temperature point is preferably got 85 ℃ ± 5 ℃.

Resistance R ₀Resistance is 100K Ω-150K Ω/0.25W, for making series connection indicator lamp LAMP ₁Brighter, divider resistance R ₀Preferably get fixed carbon resister 110K Ω/0.25W.Indicator lamp LAMP ₁Specification is that 6mm * 15mm or 6mm * 10mm can.From economic consideration, indicator lamp LAMP ₁Preferably get neon tube.Indicator lamp LAMP ₁Whether dry for pot moisture content in the outward appearance, or when cooking under selecting power save mode, outward appearance energising situation is used.Selector switch K ₁Making energy-saving type or normal formula cooks and select to use.Normally closed type thermostat K ₀Directly series connection is become owner of on heating circuit one end, at normally closed type thermostat K ₀Two ends respectively and link a selector switch K ₁, and and link a string branch, series branch is by resistance R ₀String indicator lamp LAMP ₁Form, all the other circuits remain unchanged.Selector switch K ₁Be chosen under the power save mode: heat-generating disc EH has under certain moisture content in cold conditions and interior pot and connects power supply, and rod button K does not close ₃The time, because of normally closed type thermostat K ₂With normally closed type thermostat K ₀Be normally closed switch, reach the preceding heat-generating disc EH of its temperature controlling point and get electric work that indicator lamp LAMP cooks ₂Bright.Normally closed type thermostat K after reaching 73 ℃ ± 2 ℃ ₂Disconnect, heat-generating disc EH dead electricity is done insulation indicator lamp LAMP ₃Bright, indicator lamp LAMP cooks ₂Go out.Heat-generating disc EH connects power supply having under certain moisture content in cold conditions and interior pot, rod button K closes ₃The time, heat-generating disc EH gets electric work, and indicator lamp LAMP cooks ₂Bright, after interior pot temperature reaches 100 ℃, normally closed type thermostat K ₀Disconnect.Heat-generating disc EH dead electricity, indicator lamp LAMP cooks ₂Go out wet insulation indicator lamp LAMP ₁Bright, after pot temperature drops to 85 ℃ ± 5 ℃ values in treating, normally closed type thermostat K ₀The closure that resets, wet insulation indicator lamp LAMP ₁Go out, because of magnetic steel temperature limiter M does not reach its Curie-point temperature, rod button K ₃Still locate closure state, heat-generating disc EH gets electric reworking, and lamp LAMP cooks ₂Again bright.After interior pot temperature reaches 100 ℃, normally closed type thermostat K ₀Disconnect, heat-generating disc EH dead electricity stops heating, and indicator lamp LAMP cooks ₂Go out wet insulation indicator lamp LAMP ₁Bright, go round and begin again.In treating in the pot water critical when dry, interior pot temperature rises suddenly 100 ℃ the time, normally closed type thermostat K ₀Disconnect, main heating circuit outage, heat-generating disc EH dead electricity, indicator lamp LAMP cooks ₂Go out wet insulation indicator lamp LAMP ₁Bright.At this moment, because of the waste heat effect of heat-generating disc EH, water is thoroughly dry in the interior pot, and interior pot temperature continues to rise suddenly, when reaching 101 ℃ ± 2 ℃, and magnetic steel temperature limiter M action, rod button K ₃Insulation indicator lamp LAMP is done in tripping simultaneously ₃Bright.When last aluminium lid temperature drops to 85 ℃ ± 5 ℃, normally closed type thermostat K ₀The closure that resets, wet insulation indicator lamp LAMP ₁Go out.Do insulation indicator lamp LAMP ₃Still bright and be in dried keeping warm mode; As if connecting power supply under and the cold conditions dry at interior pot, rod button K closes ₃, heat-generating disc EH gets electric work, and indicator lamp LAMP cooks ₂Bright.Because do not have water vapour in the interior pot, last aluminium lid temperature does not reach 95 ℃ ± 2 ℃, normally closed type thermostat K ₀All the time closed, at this moment, interior pot temperature rises suddenly 101 ℃ ± 2 ℃, reaches the Curie-point temperature of magnetic steel temperature limiter M, rod button K ₃Tripping, main heating circuit outage, heat-generating disc EH dead electricity stops heating, does insulation indicator lamp LAMP simultaneously ₃Bright, and be in dried keeping warm mode.Selector switch K ₁Be chosen under the standard state: the same under the standard state with the work of mechanical type electric cooker, wet insulation indicator lamp LAMP ₁Inoperative, connect power supply, rod button K closes ₃, electric hot tray EH gets electric, and indicator lamp LAMP cooks ₂Bright, reach uniform temperature after, rod button K ₃Tripping, electric hot tray EH dead electricity, indicator lamp LAMP cooks ₂Go out, do insulation indicator lamp LAMP ₃Bright and be in dried keeping warm mode.
