Description

Multifunctional controller for electric rice pot

The utility model relates to a kind of controller of household electrical appliance, particularly a kind of electric cooker multifunctional controller.

Existing electric cooker has only heating and heat insulation function, therefore the scope of application is restricted, and can not control electric cooker heat time heating time as required arbitrarily, operate very inconvenient, a kind of electric cooker multifunctional controller is disclosed in CN2113699U, it consists of: outside by plastic casing make one box-like, on the front plate of housing, be provided with quartz clock, when pilot bulb and control are made a noise and the control electric cooker change-over switch of opening, in the box-like housing electronic quartz clock is housed, controller circuit board, single-phase three pole sockets, relay and buzzer etc., though but it has the automatic function of opening of starting switch of timing controlled household electrical appliance, its structure is complicated, the cost of manufacture height, function of use is less, is unfavorable for popularizing.

The purpose of this utility model is that design is a kind of simple in structure, easy to use, the electric cooker multifunctional controller that function is complete.

The purpose of this utility model realizes by following structure: the electric cooker multifunctional controller, include the time switch of contact-carrying, its main feature is: be provided with on time switch and be subjected to its time-controlled movable contact and reverse movable contact, correspondence position at two movable contacts has the fixed contact that is connected with reducing transformer, reverse fixed contact, wherein fixed contact and the K switch of connecting electric cooker ₁, K ₃With the K switch of connecting reducing transformer ₂Connect, oppositely fixed contact and the K switch of connecting reducing transformer ₄Connect.The utility model makes in the default time by time switch and drives movable contact, reverse movable contact priority and fixed contact, and oppositely fixed contact is connected, and and K switch ₁, K ₂, K ₃, K ₄Co-operate realizes following new function:

1. the high temperature clocking capability of electric cooker;

2. the low temperature clocking capability of electric cooker;

3, the self-clocking alternating temperature function of electric cooker;

4, the not-time function of electric cooker high temperature or low temperature;

Above function has not only been simplified the using method of electric cooker, and has increased the scope of application of electric cooker, makes it boiling, stewes and endures various food.

Description of drawings of the present utility model is as follows:

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

Among the figure: 1 time switch, 2 movable contacts, 3 fixed contacts, 4 reverse fixed contacts, 5 reverse movable contacts, 6 K switch ₁, 7 K switch ₂, 8 K switch ₃, 9 K switch ₄, 10 reducing transformers, 11 electric cookers, 12 contact arch bars.

The utility model will be further described below in conjunction with drawings and Examples.

As shown in Figure 1: the utility model includes the time switch 1 of contact-carrying, be provided with movable contact 2 on time switch, oppositely movable contact 4 has the fixed contact 3 that is connected with reducing transformer 10 at the movable contact correspondence position, reverse fixed contact 5, wherein fixed contact 3 and the K switch of connecting electric cooker ₁, K ₃With the K switch of connecting electric cooker by reducing transformer ₄Connect; Reducing transformer can be selected ZQ15 type silicon diode, K for use ₁, K ₂, K ₃, K ₄Can be similar to three gears on the fan and the key switch of lamp, work as K ₁, K ₂, K ₃In any one switch press, other two switch takeoffs K automatically ₄Be an independent switch, electric cooker 11 is a heating wire.

Operation sequence of the present utility model is as follows:

1, plug in, the time switch 1 that turns clockwise, arch bar 12 jack-up contacts 2 in contact are connected with 3, and electric current makes K from 2 through 3 ₁, K ₂, K ₃Charged.

2, press K ₁Or K ₃The high temperature key, the 220V alternating current leads directly to electric cooker, forms alternating current circuit, and electric cooker produces high temp effect, controller performance high temperature clocking capability.

3, as pressing K ₂The low temperature key, the 220V alternating current becomes 80V left and right sides direct current by silicon diode, forms DC circuit, and electric cooker produces low temperature (little fire) effect, controller performance low temperature clocking capability.

When 4, needing controller performance self-clocking alternating temperature function.As long as plug in, time switch 1 is rotated to the high temperature required time, press K simultaneously ₃, K ₄High temperature key and low temperature key.This moment, time switch made contact 2 be connected with 3, and electric current forms the 220V alternating current circuit, and electric cooker produces high temp effect.When required time finishes, separate automatically with 3 contact 2, and counter-contact 4 and 5 is from being dynamically connected.220V alternating current 4 and 5 passes through K ₄The low temperature key becomes 80V left and right sides direct current after silicon diode, forms DC circuit, and electric cooker produces low temperature (little fire) effect automatically.Treat that food boils to required degree, is cut off the power supply by operator oneself.

5, inhour rotation time switch 1, rotate 45 ° after key switch K ₁, K ₂, K ₃Charged for a long time, press temperature required key again, just make electric cooker be in temperature required state for a long time, cut off the power supply until operator oneself.

Claims

1, a kind of electric cooker multifunctional controller, include the time switch 1 of contact-carrying, it is characterized in that: on time switch, be provided with movable contact 2, reverse movable contact 4, at the movable contact correspondence position fixed contact 3 that is connected with reducing transformer 10, reverse fixed contact 5, wherein fixed contact 3 and the K switch of connecting electric cooker are arranged ₁, K ₃With the K switch of connecting reducing transformer ₂Connect, oppositely fixed contact 5 and the K switch of connecting reducing transformer ₄Connect.
