Abstract

The utility model provides a far-infrared stove with distance set, which is used for regulating the distance between the bottom of a cooker and a heat source through an elastic extension mechanism which is composed of a guide shaft of an outer sleeve which is fixed between an upper bottom plate and a thermal insulation mica plate and can press a spring and a core axle which is provided with a locking gear. Through a sealing mode that the aluminium silicate fibre is filled among a plate core, a pressing ring and a metal disc of a cooker plate, the service life of electric heating elements can be enhanced so that the utility model can ensure that the distance between the bottom of a cooking pot and the heat source is the nearest, and enhance thermal efficiency and applicability. The utility model saves electricity, compared with common electrothermal stoves, energy can be saved by more than 20 percent; the utility model has the advantages of long service life, safety, and sanitation.

Description

far-infrared stove with distance set

The utility model relates to a kind of stove and accessory, and especially a kind of pan to different cambered surfaces and bore can both keep the bottom of a pan and the thermal source far-infrared oven apart from the capable of setting distance of the best.

The general furnace energy-saving of infra-red furnace is well-known, but be used to the infra-red furnace commodity of cooking in the market, ubiquity following deficiency: 1, the supporting of stone or metal plate for standing a stove on as a precaution against fire top (in order to the supporting cooker) immobilizes, the bottom of a pan (kitchenware heating surface) is different with its size and dimension with the distance of the element (thermal source) of infra-red radiation.More greatly, the bottom of a pan is just far away from thermal source as pan, and the pot head gets slowly with regard to hot, make full use of heat energy, the pan that will finalize the design often, and this has just limited the scope of application of stove and accessory.2, the heating wire life-span not long, use the several months that the fracture of wire phenomenon is promptly arranged, mostly be the oxidation reason greatly.3, effect of heat insulation is not ideal enough, switches on after half an hour, and the stove table promptly has hot phenomenon, illustrates that thermal losses is bigger.

The purpose of this utility model provides a kind of elastic telescopic heat-generating disc that has, and can both keep optimum distance to the bottom of a pan of Different Plane or cambered surface, thermal efficiency height, and adaptability is strong, the far-infrared oven of the capable of setting distance of long service life.

The utility model is to be with the guide shaft of compressible spring and the distance that elastic telescopic mechanism that the mandrel of locking mechanism forms regulates cooker bottom and thermal source is housed by be fixed on outer between upper plate and the heat insulation micarex by equiblibrium mass distribution, the sealing means of filling alumina silicate fibre between dish core, trim ring and the metal dish of employing stone or metal plate for standing a stove on as a precaution against fire reaches and improves the heating life-span, and long purpose increases the service life.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model upward view.

Fig. 2 is the utility model structural representation.

Fig. 3 is that the utility model K is to schematic diagram.

Fig. 4 is the utility model vertical view.

Structure of the present utility model is: the electrical box (1) that fixed power source switch (22), temperature regulating switch (23), indicator lamp (21,24), commutation diode and electric wire etc. are housed in circular housing (2) bottom one side, opposite side cartridge socket (16) is established thermal insulation layer (4) between the oblique heat transfer device (13) of shell (2) and upper end abduction.Trim ring (8), the porcelain tube (12) of the far-infrared radiation element (9) that the dish core (10) that the stone or metal plate for standing a stove on as a precaution against fire (5) that is provided with on stove top is made by refractory material, quartzy pipe box nichrome aluminum alloy resistance wire constitute, metal dish (6), catch net (7), band supporting (11) constitute.Fill alumina silicate fibre between dish core, trim ring and the metal dish, dish core the best selects for use fire clay to ooze glass fibre and brown sugar water is made.The major function of stone or metal plate for standing a stove on as a precaution against fire is to produce the far-infrared radiation source; and stop infrared ray to be propagated towards the direction except that stone or metal plate for standing a stove on as a precaution against fire top; fill alumina silicate fibre between dish core, trim ring and the metal dish; make it in galvanization, not have cross-ventilation; an and heat-blocking action; metal dish is except bearing combustion chamber, heat-barrier material, and also the heat with itself is transmitted on the pan of trim ring and contact with it, and catch net prevents that foreign material from falling into combustion chamber.

The elastic telescopic mechanism (14) that is fixed on the stove middle and lower part is fixed on the mandrel (18) that outer between upper plate (3) and the heat insulation micarex (15) be with the guide shaft (20) of compressible spring (19) and locking mechanism is housed by equiblibrium mass distribution and forms, fix by heat insulating washer (17) and stone or metal plate for standing a stove on as a precaution against fire, its effect is to hold stone or metal plate for standing a stove on as a precaution against fire, it is contacted with the cooker bottom all the time, by adjusting nut, make base plate keep poised state.Leave certain space between heat transfer device and the stone or metal plate for standing a stove on as a precaution against fire, be used for reducing the heat conduction.

Use of the present utility model is:

Cooker is supported by heat transfer device, for the directly load-bearing of cooker stone or metal plate for standing a stove on as a precaution against fire of minor diameter, if cooker at the bottom of the arc, then the supporting on the trim ring is pushed down in its bottom, and the stone or metal plate for standing a stove on as a precaution against fire pressurized moves down, if flat cooker, stone or metal plate for standing a stove on as a precaution against fire is pressed close to cooker bottom surface (because the baseplane is by heat transfer device supporting) under free state.In plug insertion socket, plug inserts external power jack, push switch (22), the electric furnace energising, indicator lamp is bright, and electric furnace is in (110KV) work under the halfwave rectifier state, firepower weak (weak fire), by logical switch, heating under total head, work (220V).Electric furnace is operated in strong fiery state, and red led is bright, and the on off operating mode of by-pass cock can carry out the selection of weak fire or strong fire.

The utility model to the pan of different cambered surfaces (bore), can both guarantee that the bottom of a pan and thermal source are nearest owing to adopt the elastic telescopic heat-generating disc, has both improved the thermal efficiency, has also enlarged the adaptability of stove and accessory.And owing to allow heater (heating wire) be in closed state, oxidation weakens greatly in the heating process, thereby improve heater service life, be more than 8000 hours, adopt the insulation mode of " intercept, conduct, reflect " three combinations simultaneously, heat-energy losses is reduced to a minimum.Therefore, use the utility model power saving, more energy-conservation more than 20% than general electrothermal furnace, and safety, health.
