Description

Domestic kitchen electric utensil distribution box

The utility model relates to a kind of low-voltage distribution equipment, particularly a kind of supporting power distribution cabinet that is used for family's electric cooking appliance.

Along with the continuous development of China's economic construction, electrified counties and cities are on the increase, and the use of family's electric cooking appliance is also more and more general, and kind is also very many, and the power distribution equipment that matches with it seems very simple and crude.Common family's electric cooker power distribution equipment is installed on the small distribution plate by plug-in strip, socket mostly and constitutes, at kitchen temperature height, in dust, the oil smoke environment how, electrical equipment partly is corroded easily, wears out, even the generation leaky, neither attractive in appearance dangerous again, its structure also is unfavorable for cleaning, and function singleness can not adapt to the more needs of Modern Family's electric cooker apparatus kind.

The purpose of this utility model is the use for adaptation Modern Family electric cooking appliance, and designs a kind of power distribution cabinet, considers that from aspects such as convenient and practical, energy-saving safety, favourable cleanings it should have overcurrent overheat and protect automatically; Temperature control (being the firepower size) is regulated; Regularly connect; Regularly turn-off; News are rung and are reported; LED digital display electronic clock; And multiple functions such as normal open socket and smoke exhaust ventilator private jack, monnolithic case is attractive in appearance.

The purpose of this utility model is achieved through the following technical solutions:

Family's electric cooker power distribution cabinet, have a cabinet and power distribution panels, by air switch, the clock timing circuit, relay, thermoregulation circuit, warning circuit, socket, indicating circuits etc. constitute its circuit partly, it is characterized in that power distribution panels is located in the cabinet, its front is a glass door, has the power supply lead wire breach below doorframe; Adopt clock to regulate button incoming timing signal, the pulse signal of electronic clock output makes relay J 1, J2 adhesive after amplifying, the switching of normally closed, the normally opened contact by J2, timing alarming circuit is connected in the switching of regularly logical socket of control and regularly disconnected socket power simultaneously; Regularly breaking circuit and thermoregulation circuit are combined, and adopt regulator potentiometer, by the angle of flow of bidirectional trigger diode control bidirectional triode thyristor, thereby regulate the height of electrical appliance both end voltage, the zero line of the regularly disconnected socket of thermoregulation circuit control.

The cabinet of the utility model power distribution cabinet can be made with flame retardant type fiberglass reinforced plastics or phenolic resin material, and the big cambered surface of single is adopted in the positive front of cabinet, about two seamed edges adopt little cambered surface of single and big cambered surface to join.

According to the family's electric cooker power distribution cabinet that the utility model proposes, changed the design and the outward appearance appearance of existing family expenses electric cooker distribution board, and the selecting for use of sheathing material, make the user safe in utilization, convenient, be convenient to cleaning.Partly overall structure is simple, multiple functional for its circuit, and assembly and adjustment is easy, and is with short production cycle, and cost is low, and dependable performance is suitable for and the supporting use of family's electric cooking appliance.

Fig. 1 is profile and the distribution panelboard face layout plan of the utility model embodiment;

Fig. 2 is that block diagram is formed and concerned to circuit;

Fig. 3 is circuit theory diagrams.

According to accompanying drawing the utility model is further described below:

As Fig. 1, the utility model outward appearance is cabinet type appearance, the big cambered surface of single is adopted in the positive fronts of cabinet 8, about two seamed edges adopt little cambered surface of single and big cambered surface to join, other each face is the plane, power distribution panels 10 adopts and crouches into formula, big cambered surface of single or flat glass door 7 are adopted in its front, are convenient to the user and change, and glass door adopts the magnetic latch to end and unlatching, doorframe is following for the power supply lead wire of electric cooking appliance leaves suitable breach 19, does not hinder closing of glass door.

Indication and the Operand device arranged on the power distribution panels 10 have: two air switch 9(ZK1, ZK2), electronic clock display panel 11, four clock buttons 12, voltmeter 14, thermoregulation knob 13, normal open Duplex socket 16, regularly logical socket 18, regularly disconnected socket 20, each socket top is equipped with power supply indicator 17, is provided with smoke exhaust ventilator socket 15 and loudspeaker aperture 21 in the side of cabinet.

The cabinet body structure of power distribution cabinet can be divided into cabinet and base two parts, has paperback simultaneously and adorns two kinds of mounting meanss with crouching, and is convenient to manufacturer production and user and selects to use.

Suitable position at the cabinet upper and lower surface has the ventilation louvre.

Shown in Fig. 2, Fig. 3, the circuit of the utility model power distribution cabinet is mainly by air switch ZK1, ZK2, clock timing circuit 1(also can be used as electronic clock simultaneously), relay 2, thermoregulation circuit 3, warning circuit 4, socket 5(ZC1, ZC2, ZC3, ZC4), indicating circuit more than 6 parts are formed, and its circuit working principle is as follows:

Realize the overcurrent and overheating protection of circuit by air switch, wherein air switch ZK1 directly controls smoke exhaust ventilator private jack 15(ZC1) and normal open Duplex socket 16(ZC2) live wire; Air switch ZK2 is by relay 2(J2) control regularly logical socket 18(ZC3) and the socket 20(ZC4 that regularly breaks) and the live wire of warning circuit 4 power supplys.And relay 2(J2) control by clock control circuit 1.

Clock part 1 is owing to will so its power supply does not pass through air switch ZK2 control, and directly be connected on the civil power as electronic clock simultaneously.

Consider with minimum components and parts to reach needed function that this example is only finished regularly logical and regularly disconnected function simultaneously with two pairs of contacts of a relay 2.

According to the common needs of family cooking, regularly deenergizing and thermoregulation circuit are organically combined, the zero line of the regularly disconnected socket of thermoregulation circuit control.

The realization of timing function is such: adopt clock to regulate button 12(KN1～4) with required moment input electronic clock 11(FR), arrived predetermined instant, electronic clock will be exported a pulse signal, make clock little relay J 1 adhesive partly through amplifying circuit, little relay contact is connected big relay 2(J2) power supply of coil, big relay J 2 adhesives, normally-closed contact disconnects, and turn-offs regularly disconnected socket 20(ZC4) power supply; Normally opened contact engages, and connects the logical socket 18(ZC3 of timing), also connect timing alarming circuit 4 power supplys simultaneously, after transformation, rectification, voltage stabilizing, ring integrated package and loud speaker YD use for the music news.The duration that the music news are rung is about 30 seconds.The socket electrifying electricity, the corresponding indicator light in its top is bright, the socket outage, corresponding indicator light extinguishes.

Temperature adjustment (being the firepower size) thus function is to regulate electrical appliance (load) both end voltage by the angle of flow of control bidirectional triode thyristor KS to realize.Regulator potentiometer W(is the thermoregulation knob 13 on the power distribution panels), can pass through the conducting degree that bidirectional trigger diode DIAc controls bidirectional triode thyristor, thus the height of regulating load both end voltage.The indicator light of corresponding regularly disconnected socket 20 tops can light and shade change along with voltage swing, and voltmeter also can indicate the size of relevant voltage simultaneously, and the variation of voltage is continuous.
