Abstract

The utility model relates to an electrothermal stove for cooking, particularly an electric stove used in household cooking. The utility model is mainly characterized in that a pair of contact points are arranged in a temperature regulator, the movable contact point of the contact points is directly connected with the temperature regulator, a static contact point on the lower part is connected with a second contact point of a constant temperature timer by an electric heating wire, and meanwhile a static contact point on the upper part is connected with a third contact point of the constant temperature timer through a relay switch J <1-2>and a resistor R <4>. Therefore, the utility model can guarantee the stabilization of the quality of the cooked food, can save electricity at the same time, and no person is needed to monitor the cooking process.

Description

Temperature adjustment for cooking is electric furnace regularly

The utility model relates to a kind of Electricthermal furnace for cooking, especially refers to culinary electric furnace in the family.

At present, common electric food warmer is to be combined by pot and electric furnace thereof, can give the time that choosing begins to heat, regulate the required temperature of the cooking and the time of heating, in fact, be meant pot and interior food thereof the heat time heating time of gastronomical process, from normal temperature to temperature required time of the cooking, add the time sum that keeps one section constant cook temperature, and the big or small food different with the heat conduction degree of cooking food amount is to very big to the temperature required time phase difference of the cooking from normal temperature, many again cooking methods are to keeping one section constant cook temperature requirement very tight (directly influencing cooking quality), therefore, existing electric food warmer is difficult to guarantee automatically cooking quality.

In view of this, the purpose of this utility model provides regularly electric furnace of a kind of temperature adjustment for cooking, can control to keep the required time of constant cook temperature, improves cooking quality.

The purpose of this utility model is achieved in that two ends that it is included in supply socket connect respectively to give and selects timer and constant temperature timer, give again and select timer to connect thermosistor, the constant temperature timer connects heating wire, it is characterized in that: be provided with a double-contact in the thermosistor, the movable contact of this double-contact directly is connected on the thermosistor, the stationary contact of below is through second contact of heating wire connection constant temperature timer, and the stationary contact of top is through the switch J of relay simultaneously _1-2, resistance R ₄The 3rd contact that connects the constant temperature timer.

The movable contact of above-mentioned double-contact is welded on energy storage spring seat one end, and the other end of this energy storage spring seat is supported in bimetal leaf one cantilever end through the porcelain push rod, and stationary contact is separately fixed on the holder of movable contact upper and lower.

Because adopt such scheme: can guarantee the cooking food steady quality, gastronomical process does not need manual monitoring again, also reduce power wastage simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments circuit theory diagrams.

Fig. 2 the utility model exemplary embodiments thermosistor cross-sectional schematic.

Among the figure: G ₁Give and select timer G ₂Constant temperature timer D thermosistor D _KDouble-contact K ₁Movable contact K ₂, K ₃Stationary contact L heating wire J relay J _1-1, J _1-2The normally opened contact C of J ₁, C ₂Indicator lamp R ₁, R ₂, R ₃, R ₄Resistance K _PSupply socket 1, temperature adjustment bar 2, energy storage spring seat 3, bimetal leaf 4, porcelain push rod 5, holder

Present embodiment mainly comprises giving and selects timer G ₁, constant temperature timer G ₂, thermosistor D, heating wire L and relay J, as shown in Figure 1.

Give and select timer G ₁(synchronous motor timer) wherein connects supply socket K with first contact for giving the time that choosing begins to heat _PAn end, and second contact connects thermosistor D, is provided with a double-contact D among this thermosistor D _K, this double-contact D _KA stationary contact K ₃(below stationary contact) connects the end of heating wire L, and another stationary contact K ₂(top stationary contact) connects the other end of heating wire L through relay J; Constant temperature timer G ₂First contact connect supply socket K _PThe other end, second contact connects the other end of heating wire L, simultaneously through resistance R ₂Connect to give and select timer G ₁The 3rd contact, constant temperature timer G ₂The 3rd contact through resistance R ₄, relay J normally opened contact J _1-2, connect double-contact D _KA stationary contact K ₂

Double-contact D _KMovable contact K ₁Be welded on energy storage spring seat 2 one ends, and the other end of this energy storage spring seat 2 is supported in bimetal leaf 3 cantilever ends through porcelain bar 4, its interior micrometer adjusting screw of temperature adjustment bar 1 usefulness is regulated lower end porcelain bar pressure head and is contacted with energy storage spring seat 2, at movable contact K ₁Upper and lower is respectively equipped with the stationary contact K that is fixed on the holder 5 ₂, K ₃

The operation of present embodiment and principle thereof:

At first, regulate the temperature adjustment bar 1 of thermosistor D, determine the steady temperature of cooking food, then regulate constant temperature timer G ₂(wherein first and second contacting), the time of promptly determining to keep constant temperature, constant temperature timer G at this moment ₂First, second contact be communicated with, regulate to give again and select timer G ₁(wherein the first, the 3rd contacting) promptly gives ordering and begins to cook heat time heating time; Supply socket K _PPlug (constant temperature timer G ₂First contact and second contact are connected automatically), up to reach give order begin to cook heat time heating time after, arrive to give and select timer G ₁After, wherein first contact and second contact are just connected automatically, so, the double-contact D of thermosistor D _KMovable contact K ₁With below stationary contact K ₃Connect, heating wire L switches on (being the heating kettle body), when heating wire L heating-up temperature reaches required constant temperature, and movable contact K ₁Leave below stationary contact K ₃And stationary contact K above connecting ₂, relay J energising, normal open switch J _1-1, J _1-2Connect, through resistance R ₄Connect constant temperature timer G ₂The 3rd contact and second contact, at this moment, constant temperature timer G ₂Just pick up counting, finish, constant temperature timer G up to heating ₂Disconnect, circuit disconnects, i.e. heating stops.

In sum:

Because constant temperature timer G ₂The time that shows is the real heated at constant temperature time, and is not subjected to the influence to the food heat temperature raising time in the pot, therefore can guarantee the quality of cooking food.
