Description

Domestic electrothermal multipurpose kitchen range

This product relates to household kitchen electric heating appliance patent.

At present, the electric household appliance production development is very fast, but function is all less; For example: electric frying pan only is applicable to stir-fry, prepares food, and electric cooker only is used to do meal, stewes thing, and function is few.This product is to design on the basis of former electric cooker, and the third generation household appliances that it can be used as city or urban households kitchen use; But general bulk/volume buying.It has two accessories (outer cover and power line), use pans such as frying in shallow oil in the ordinary course of things, fry, boil; Cook, heat up water and during stewed thing, use outer cover and get final product with various aluminum pots in the family; Also have the electronic timer function simultaneously, can be family and regularly cook.At present, also can utilize pressure cooker and timer regularly to cook congee in the morning for family; In addition, how also can be used as electric chafing dish with kitchen range enters on the galley dresser of family.

The utility model is achieved through the following technical solutions.

This utility model is to increase some heatings and control element on the basis of former electric cooker, to realize the function of electro heating multipurpose kitchen range.It is made up of heating, control element, display element, shell and outer cover etc.; Heating is an electrothermal tube, or heat-generating disc, and control element has switch assembly, temperature regulating switch, temperature detector etc., and display element adopts little neon lamp and is fixed on the shell; Supply socket and switch assembly etc. all are contained on the shell.Heating circuit controls switch adopts at the control contact two ends of former electric cooker temperature regulating switch in parallel, to realize that major loop (heater element) is controlled by a plurality of control element; Make it realize the electric range functions of using more.Operation principle of the present utility model is: when using the electric frying pan function to cook, as long as open electric switch, the heating of major loop must be electric, and the generation heat has heated the container on the kitchen range face, but the user must cook with flat metal pan (also can use on the electromagnetic stove); When using the electric cooker function, the former electric switch of opening will turn-off (when adopting temperature regulating switch, temperature regulating switch should be transferred at little temperature shelves), uses the limit temperature function on the switch assembly to be the electric cooker functional status, adds outer cover, uses general flat aluminum pot to cook; When as electric chafing dish, use as long as can work as electric chafing dish with flat metal pan and temperature regulating switch.

Below will be described in further detail the utility model by instantiation.

Fig. 1 is the front view of embodiment.

Fig. 2 is the circuit theory diagrams of embodiment.

Fig. 3 is the schematic diagram of switch assembly.

Fig. 4 is the temperature regulating switch structural representation.

Annotate: among Fig. 1 to Fig. 4, the represented meaning of each symbol is as follows:

1, is the heat-generating disc that is cast with heating; 2, be a pot body holddown groove

3, be temperature detector 4, heating (electrothermal tube) 5, be heat-insulating shield

6, switch assembly 7, toggle switch 8, supply socket

9, temperature regulating switch 10, shell and outer cover 11, indicator lamp

K1 is that the limit temperature control contact K2 on the switch assembly is an electrical switching contact

K3, K4 are that toggle switch (adjusting power) RD is timing and indicator lamp

R1, R2 are heating (electrothermal tubes)

The utility model is to increase some heatings and control element has been realized functions such as electric frying pan, electric cooker, electric chafing dish on the basis of existing electric cooker.Heat-generating disc 1 adopts the metal casting that is cast with two electrothermal tubes 4, in the center of electric hot tray temperature detector 3 is housed, and there is a heat-insulating shield 5 the heat-generating disc below, and it is to be used to support electric hot tray; Supply socket 8, electric switch K2 and switch assembly 6 all are fixed on the shell.Electric switch can be a common electric switch, but preferably a kind of temperature regulating switch 9, forgotten to have got or power switch when forgetting to turn off the temperature that makes on the kitchen range and surpassing the scale at temperature regulating switch place when thing on the electric range like this, just automatic disconnection of temperature regulating switch 9, thus kitchen range can not met accident.When electric frying pan functions such as frying in shallow oil, fry, boil, rotate the temperature regulating switch knob, will use temperature regulating switch to connect major loop, make the electric hot tray heating and realization electric frying pan function; Two change-over switch K3, K4 by switch assembly regulate electricity cooker power, the adjusting of firepower when realizing cooking.During the electric cooker function,,, make assembly 6 have the effect of limit temperature, by switch contact K1 control main circuit power supply by the link rod of switch assembly by the actual temperature of temperature detector 3 measurement pots for cooking rice; And the temperature regulating switch of this moment can only be transferred in insulation (electric cooker insulation) below the temperature, promptly has the automatic electric rice cooker function this moment.Fig. 4 is circuit theory diagrams, and its operation principle is: when using the electric cooker function, switch assembly electrical contact K1 closure is pressed switch assembly 6, makes temperature limit switch K1 closure, the major loop closure, and heating R gets electric and generates heat; This has just heated the container that places on the kitchen range face, and when the temperature of container reached 103 ℃, the temperature that is close to the sensing magnet steel on the temperature limiter of container bottom reached this temperature; At this moment, its magnetic conductivity sharply descends, thereby it can't be inhaled mutually with permanent-magnet steel again, under the gravity effect of the repulsive force of the take-off spring of temperature limiter and permanent-magnet steel, permanent-magnet steel falls fast, simultaneously the switch assembly connecting rod is depressed, the electrical contact K1 on the switch assembly is separated, circuit promptly is cut off; So just realized the function of electric cooker.When we will be placed on when being used as electric chafing dish on the table and using, then should open temperature regulating switch K2 and pre-set temperature required shelves, this moment, temperature regulating switch K2 should be in closure state, and K3, K4 connect power supply and regulate chafing dish power, get electric heating at heating R, the pot on the heating-range face; When the temperature on the kitchen range face surpasses when temperature is set, temperature regulating switch K2 disconnects and treats to the temperature back K2 that descends closedly again, makes that temperature can not surpass the temperature that pre-sets on the kitchen range face.Finish if use, must turn off temperature regulating switch and K3, K4 are placed off-state.

The utility model kitchen range have the function of electric cooker, electric frying pan; And,, can be placed on the fooled electric chafing dish of table and use because volume is little.In addition, kitchen range is provided with fixedly combined, is convertible into split type device again--and-holddown groove 2, it can match and interlock into fixedly combined with special pot body (the pot body has three pin).On shell, add regularly function, adopt present domestic electronic timer circuit (LM8363), adjustable to the control time; And free numeral demonstration and sound warning etc.
