Abstract
The utility model discloses a kind of Steam roasters of efficient hot-air convection current to be equipped with the heating chamber of connection including providing the liner of high-temperature steam by steam generation facility in the liner；Its interior heat generating device for being equipped with the flabellum for flowing air or steam circulation and reheating is carried out to air or steam of the heating chamber, the heat generating device includes heater, the outer surface of the heater, which is covered, is wrapped with heat-conducting metal layer, and the heat-conducting metal layer outer surface forms the radiating surface in squama aliform；The utility model is made there are good thermally conductive medium between heater and air or steam, heat transfer efficiency is higher by the way that heat-conducting metal layer is arranged on the heater surface of heat generating device；Heat-conducting metal outer surface forms the radiating surface in the distribution of squama aliform simultaneously, increases the contact area with air or steam, and heat-conducting effect more preferably, avoids the directly exposed formation dry-fire condition of heater, the service life is longer.
Description
Technical field
The utility model relates to Steam roaster, especially a kind of Steam roaster of efficient hot-air convection current.
Background technique
Steam roaster is that a kind of air that can not only directly heat toasts food, but also can pass through and generate high-temperature steam
Steam-heated kitchen cooking equipment is carried out to food.
The problem of in order to avoid food uneven heating, liner is internally provided with flabellum and heat generating device is constituted in Steam roaster
The hot air convection structure in portion flows inner air or steam generation by flabellum, and heat-generating pipe then make it is cold after being contacted with food
But air or steam is by reheating, to keep internal temperature, thermal field is more uniform.
But it is currently used for the heat generating device of internal hot air convection, it is right using the conventional heat-generating pipe that surface is smooth
The heat transfer efficiency of air or steam is lower, causes to be easy aged deterioration, service life is short in " dry combustion method " state often.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of Steam roaster of efficient hot-air convection current.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of Steam roaster of efficient hot-air convection current, it is described including providing the liner of high-temperature steam by steam generation facility
The heating chamber of connection is equipped in liner；The heating chamber is equipped with the flabellum for flowing air or steam circulation in it and to air
Or steam carries out the heat generating device of reheating, the heat generating device includes heater, and the outer surface of the heater, which is covered, to be wrapped with
Heat-conducting metal layer, and the heat-conducting metal layer outer surface forms the radiating surface in squama aliform.
The heat-conducting metal layer is aluminium.
The heat generating device is tubulose.
The heat generating device is annularly arranged around the flabellum.
The beneficial effects of the utility model are: making to send out by the way that heat-conducting metal layer is arranged on the heater surface of heat generating device
There are good thermally conductive medium between hot body and air or steam, heat transfer efficiency is higher；Heat-conducting metal outer surface, which is formed, simultaneously is in
The radiating surface of squama aliform distribution, increases the contact area with air or steam, and heat-transfer effect more preferably, avoids heater directly exposed
Dry-fire condition is formed, the service life is longer.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of the utility model heat generating device.
Specific embodiment
Referring to Fig.1, Fig. 2, a kind of Steam roaster of efficient hot-air convection current, including high-temperature steam is provided by steam generation facility
Liner 1, the heating chamber 2 of connection is equipped in liner 1；Heating chamber 2 be equipped in it the flabellum 3 that flows air or steam circulation with
And the heat generating device 4 of reheating is carried out to air or steam.
Heat generating device 4 includes heater 41, and the outer surface of heater 41, which is covered, is wrapped with heat-conducting metal layer 42, makes heat generating device 4
There are good thermally conductive medium between air or steam, heat transfer efficiency is higher；42 outer surface of heat-conducting metal layer, which is formed, simultaneously is in
The radiating surface of squama aliform, is capable of increasing the contact area with air or steam, and heat-transfer effect more preferably, avoids heater directly exposed
Dry-fire condition is formed, the service life is longer.
Preferably, heat-conducting metal layer 42 is aluminium, can be attached to 41 surface of heater by integrated die-casting, material cost compared with
Low, heating conduction is superior.
Specifically, heat generating device 4 is tubulose, and is annularly arranged around the flabellum 3, makes to disturb the sky flowed through through flabellum 3
Gas or steam can flow through heater 4 and carry out reheating, and the temperature difference that Steam roaster has been effectively ensured is uniform.
The utility model has the advantages of simple structure, by the transformation to heating device 4, so that it is more superior thermally conductive to have it
Performance, while increasing its contact surface area, heat transfer efficiency is improved, it is more energy-efficient.
