Description

But a kind of heater of electromagnetism heating

Technical field

The utility model relates to a kind of heater, but utilizes the heater of the electromagnetism heating of solenoid heating specifically.

Background technology

At present, chafing dish is all more in vogue throughout the country, and general chafing dish dining room is the hot pot stove that adopts burning organic-fuel or coal gas, during actual the use, and the difficult control of stove fire, and the stove and accessory temperature is higher, scalds the diner easily, and not too safe.Also having many families and restaurant that electromagnetic oven is placed on the table uses, electromagnetic oven generally comprise favourable with solenoid heating heater and be arranged on the heater, the heating surface of microcrystal glass plate system, the magnetic conduction pan just can be placed on this heating surface and be heated.Now, also there are some to utilize the dining table of solenoid heating to be invented equally, as the patent No. is the Chinese utility model patent " dining table of band electromagnetic oven " of ZL02272402.8 (publication number is CN2633089Y), disclose a kind of dining table that can be used on the band electromagnetic oven of wooden desktop, it has counterbore on the table, be placed with solenoid, microcrystal glass plate in the counterbore and be used to shelve the carriage of microcrystal glass plate, and the controller of solenoid and its below links to each other; And for example the patent No. is that the Chinese utility model patent glass dining table of electromagnetic oven " band " of ZL02272412.5 (publication number is CN2554956Y) also discloses a kind of dining table with electromagnetic oven, it includes placement and offers solenoid and the controller that links to each other with this solenoid in the aperture on the table, and also has additional the desktop of a toughened glass on this desktop; My patent formerly and for example, the patent No. are the utility model patent " a kind of dining table that can be used for the electromagnetism heating " of ZL200520101328.9 (notification number is CNY), applicable to the dining table of non-high-temperature resistant material system desktop.

Wherein, but be used for the heater of these electromagnetism heating dining tables and the heater of electromagnetic oven, all include solenoid and be used to coil the fixed support of establishing solenoid, this fixed support need adopt insulating material, generally just adopt hardness preferably plastic production form.When reality is used, the solenoid energising is afterwards when producing eddy current with the magnetic conduction pan, itself can produce Joule heat, the temperature of solenoid can improve constantly like this, and be in the operating state of high temperature, distributed if these heats are untimely, just make solenoid itself aging easily, reduce its useful life, under the relatively poor situation of ventilation condition, particularly work as this situation that the heating surface bottom surface is pressed close on the solenoid surface, the working temperature of solenoid can reach 200 ℃ even 300 ℃, is very easy to make solenoid to burn out, perhaps dissolve, damage the fixed support under the solenoid, have potential safety hazard, and can cause electromagnetic oven or dining table cisco unity malfunction, consequence is comparatively serious.

Summary of the invention

But technical problem to be solved in the utility model is the heater that a kind of electromagnetism heating that can reduce the solenoid working temperature is provided at above-mentioned prior art present situation, uses safelyr, and the life-span is also higher.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: but be somebody's turn to do the heater that electromagnetism heats, include fixed support and coil the solenoid that is located on the fixed support, it is characterized in that: described fixed support central authorities have through hole, and are provided with a fan among this through hole.

When described heater is applied in the middle of the electromagnetic oven, heater is being fixed under the heating surface by its fixed support and electromagnetic oven internal fixation post, for providing good ventilation condition to heater, when fixing heater, can make between the bottom surface of its solenoid surface and heating surface and reserve certain spacing, with the formation circulation passage.

And when but described heater is applied in the middle of the dining table of electromagnetism heating, heater is being fixed under the heating surface (being desktop or microcrystal glass plate or toughened glass) by its fixed support and desktop bottom, for providing better ventilation condition to heater, simply, can carry out following setting: described fixed support wears its edge by screw and is fixed under the heating surface, on this screw, be equipped with pad, and the top of this pad is higher than described solenoid surface, make the solenoid surface and the desktop bottom surface of dining table by the pad nature forms bigger spacing like this, the air that the fan of fixed support central authorities is produced by boasting just can from both the gap and be passed to the external world, the circulation of air of being more convenient for;

For making assembly process simpler, also can carry out following setting: described support bracket fastened edge is provided with projection, the top of this projection is higher than the surface of described solenoid, and described fixed support is fixed under the heating surface, and this projection pastes mutually with the heating surface bottom surface, like this, make the bigger spacing of formation between solenoid and the heating surface bottom surface by projection, thereby provide the channel that ventilates preferably to solenoid.

Compared with prior art, advantage of the present utility model is: by offering through hole in support bracket fastened central authorities, and in through hole, settle fan, like this, the air that fan blows out can be fast takes the hot gas on solenoid surface to the external world, and the heat that produces during solenoid work will constantly be distributed, reach the purpose of heat radiation, cooling, give good working environment of solenoid, improved useful life, but and guaranteed the safe handling of electromagnetism heating dining table, electromagnetic oven; And, by adding pad or projection being set, make between the bottom surface of solenoid and heating surface and reserve spacing, the solenoid surface is connected with the external world, form a good ventilation channel, more help the heat radiation of solenoid.
