Abstract
The utility model relates to an electric cooking stove. A stove body is composed of a stove end and a stove seat. The stove end is overhead the stove seat. The stove end is fixedly connected with the stove seat by a supporting rod. An electric heating device is arranged in the stove end. A temperature regulating structure is arranged in the stove seat. The electric cooking stove can realize semiconductor thyristor stepless thermoregulation and has the advantages of long service life of the temperature regulating structure and the electric heating device, small heat losses and complete functions.
Description
The utility model relates to a kind of electric calorifie installation, especially a kind of electric cooking oven.
China's utility application discloses a kind of cast iron for No. 86205410 and has made up three gear directly-heated type electric frying pans, this electric frying pan is combined by pot body and electric furnace body, is provided with the electrothermal device and the armature contact formula temperature adjusting structure of heating wire form in electric furnace body.Because its temperature adjusting structure and the adjacent setting of stone or metal plate for standing a stove on as a precaution against fire that is equiped with heating wire, the high heat of sending during the heating wire energising is worked the temperature adjusting structure in hot environment, cause obviously shorten the service life of this temperature adjusting structure.And, then can't in above-mentioned abominable hot environment, use with regard to regulating effect semiconductor controllable silicon stepless temperature-regulating circuit preferably at all.In addition, because its binding post as electrothermal wire power's joint design also is among the hot environment, the crimping point of heating wire end is very easily oxidation and damaging in this hot environment, and therefore, the service life of heating wire is also shorter.
The purpose of this utility model is the defective that overcomes furnace binding in the above-mentioned existing electric frying pan, and a kind of temperature adjusting structure electric cooking oven in service life that improves is provided.
The utility model electric cooking oven improves furnace binding, so that the temperature adjusting structure is worked in lower temperature environments.Body of heater of the present utility model is made of burner and stove seat two parts especially.Burner is built on stilts to be arranged on the stove seat, fixedlys connected by support bar between burner and the stove seat.Electrothermal device is arranged in the burner, and the temperature adjusting structure is arranged in the stove seat.In the utility model, be arranged on the stove seat because burner is built on stilts, so when utilizing the electric cooking oven cooking, though the part heat that heating sends in the burner still can pass to the stove seat by the support bar that connects burner and stove seat, but because of support bar body of rod cross section little usually, the heat that can transmit is limited, and the body of rod is exposed among the air fully, above-mentioned limited heat also will scatter and disappear in transmittance process in a large number, therefore can not make the temperature rise of stove seat too high, can guarantee to be arranged at the interior temperature adjusting structure of stove seat and in lower temperature environments, work all the time, increase service life.Simultaneously, the lower temperature environments in the stove seat also may for using the good semiconductor controllable silicon thermoregulation circuit structure of temperature adjusting performance to provide.The electrothermal device that is arranged in the burner can be the various electrothermal device that adopts in the existing electric cooking appliance, as aluminium matter heat-generating disc, heating wire etc.When electrothermal device adopts heating wire, the power connection structure of heating wire can be arranged in the stove seat.Like this, the crimping point that can avoid end element conneccting is oxidation and damaging rapidly in hot environment, thereby prolongs the service life of heating wire.
In the utility model, can in burner, refractory masses and adiabator layer be set the bottom of heating.Generally, can make refractory masses be positioned at the bottom of heating, and adiabator layer is arranged under the refractory masses.Like this, both can further stop the interior heat of burner, can reduce the unhelpful loss of heat again, play energy-saving effect to the transmission of stove seat.In addition,, also can offer louvre, under low temperature environment, work to guarantee the temperature adjusting structure at stove seat outer wall in order further to reduce temperature in the stove seat.Because burner and stove seat in the utility model are in released state basically, needn't worry to heat up in the burner too high and temperature adjusting structure in the stove seat is produced harmful effect, therefore, additional structures such as baking can further be set at the burner place, thereby make the function of electric cooking oven more perfect, constitute multi-functional electric cooker stove.
In sum, because electric cooking oven of the present utility model improves on furnace binding, the temperature adjusting structure is worked in lower temperature environments, thereby can realize semiconductor controllable silicon stepless temperature-regulating, and have temperature adjusting structure and electrothermal device long service life, thermal losses is little, function is comparatively complete characteristics.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of electric cooking oven among the embodiment.
Fig. 2 is the electrical schematic diagram of electric cooking oven.
As shown in Figure 1, the electric cooking oven body of heater among the embodiment mainly is made of burner 1 and stove seat 2 two parts, and burner 1 is built on stilts to be arranged on the stove seat 2, fixedlys connected by support bar 3 between burner 1 and the stove seat 2.Electrothermal device adopts heating wire 4, and heating wire 4 and spill supporting stone or metal plate for standing a stove on as a precaution against fire 5 thereof are arranged in the burner 1.The temperature adjusting structure adopts controllable silicon stepless temperature-regulating circuit, and its circuit board 6 and regulator potentiometer 7 are arranged in the stove seat 2.Be outside equipped with attaching plug 15 at the stove seat.Heat transmits to the stove seat in the burner in order further to stop, and is provided with refractory masses 8 and adiabator layer 9 in burner 1.Refractory masses 8 is arranged at the bottom of stone or metal plate for standing a stove on as a precaution against fire 5, and adiabator layer 9 is arranged at the bottom of refractory masses 8.In addition, be provided with louvre 10, make to have ventilation condition preferably in the stove seat 2 in the bottom of stove seat shell.In the present embodiment, for prolonging the service life of heating wire, electrothermal wire power's joint design 11 with the binding post form is arranged in the stove seat 2 especially, and the heat insulation communicating pipe 12 that ceramic material is made is set between burner 1 and stove seat 2, the end of heating wire 4 is passed and is fixed on the binding post 11 communicating pipe 12.The electric cooking oven of present embodiment also is being provided with the detachable seal bootr 13 that seals above can be with burner on the burner 1.For ease of baking with put, get food, especially seal bootr is made as separable two-layerly, and in lower floor's cover body, be provided with the built on stilts thing structure 14 of holding of horizontal stripe form.
As shown in Figure 2, electric cooking oven constitutes the stepless temperature-regulating circuit by controllable silicon SCR, diode D, resistance R, capacitor C, inductance coil L and potentiometer Rw among the embodiment, realizes temperature adjusting to heating wire P to change potentiometer Rw resistance size.
In addition, in case of necessity, can on the seal bootr 13 in the present embodiment temperature-sensing element and signal accessory power outlet be set, and on the stove seat relative set temperature-sensitive signal input socket, the temperature-sensitive signal is introduced temperature control circuit, further realize baking temperature in the cover body is controlled automatically.Simultaneously, the controllable silicon thermoregulation circuit that is adopted in the present embodiment also can be replaced by other circuit for regulating and controlling.
