Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two;
Fig. 3 is the structural representation of the utility model embodiment three;
Among the figure: 1 pot cover, 2 outer covers, 3 bases, 31 louvres, 4 pots of courages, 5 radiators, 6 power panel assemblies, 7 radiator fans, 8 electromagnetic induction heaters.
The specific embodiment
With reference to Fig. 3; A kind of electromagnetic induction heating type electric food warmer comprises pot body and pot cover 1, is provided with pot courage 4, electromagnetic induction heater 8 and radiator 5 in the pot body; Electromagnetic induction heater 8 is the coil panel assembly of coiling induction coil; The pot body comprises outer cover 2 and base 3, in the pot body, also is provided with power panel assembly 6, and power panel assembly 6 is provided with electronic components such as IGBT.In the electric food warmer course of work; The generation of alternating magnetic field is to rely on powerful IGBT element to open, turn-off generation; Therefore the IGBT element can produce a large amount of heats, and is out of control for preventing the IGBT element over-temperature, just needs to install radiator 5; And utilize the radiator fan forced heat radiation, to guarantee the job security of electric food warmer.
Embodiment one:
With reference to Fig. 1, in the present embodiment, a radiator fan 7 is installed on the radiator 5; Radiator fan is directly installed on the radiator 5; Saved existing blower tray, simplified assembly process, assembly manipulation is convenient; And radiator 5 its stability of more existing blower tray will be got well a lot; Fan is directly installed on the radiator 5, the vibrations that produce in the time of can reducing the radiator fan running, thus reduce operating noise; Existing radiator 5 is mainly the metal heat sink 5 that has the aluminium fin, and metal heat sink 5 has certain sound-absorbing effect, can further reduce the noise that the radiator fan operation produces; Existing radiator fan often only dispels the heat to the IGBT element on the power panel assembly 6; But the coil panel assembly in the electromagnetic induction heating type electric food warmer can produce heat equally, as the improvement of present embodiment, when radiator fan is installed; Only the part with radiator fan 7 is fixed in radiator 5 bottoms; And another part extends to coil panel assembly below, is used for the coil panel assembly is dispelled the heat, and has so just made full use of the forced heat radiation function of radiator fan; Nor influence the heat radiation of IGBT element, promote the whole radiating effect of electric food warmer.
Embodiment two:
With reference to Fig. 2; In the present embodiment, 7, two radiator fans 7 of two radiator fans being installed on the radiator 5 can integrative-structure; Promptly in a fan drum, be integrated with two fan monomers; Or two independent radiator fans 7, but compare existing radiator fan, the fan blade diameter of the radiator fan 7 described in the present embodiment is much smaller; These two radiator fans 7 are installed on the radiator 5; Utilize two radiator fans to dispel the heat facing to radiator 5; The wind direction of two radiator fans 7 is radial, and the wind direction between them is the convection current shape, has strengthened air and has flowed; Improve this regional radiating effect, thus the electric elements such as IGBT on the better protection power panel assembly 6; All the other beneficial effects of present embodiment are with reference to embodiment one; In addition, the duty of two radiator fans 7 can be controlled through the control system of electric food warmer, when heating like the electric food warmer small-power, selects for use a radiator fan 7 can satisfy the heat radiation requirement, saves electric energy; And when the high-power heating of electric food warmer, two radiator fans turn round simultaneously.
Embodiment three:
With reference to Fig. 3; Be with the difference of embodiment two: in the present embodiment, two radiator fans 7 are installed on the radiator 5, but two radiator fans 7 connect as one structure; One of them radiator fan 7 is installed on radiator 5 bottoms, and another radiator fan 7 extends to coil panel assembly below; With embodiment one, the radiator fan of radiator 5 bottoms is primarily aimed at the IGBT element on the power panel assembly 6, and the radiator fan of coil panel assembly below is used for the coil panel assembly is dispelled the heat; Duty with two, two radiator fans 7 of embodiment also can be controlled through the control system of electric food warmer, when heating like the electric food warmer small-power, selects for use the radiator fan of radiator 5 bottoms that the IGBT element is dispelled the heat, and saves electric energy; And when the high-power heating of electric food warmer, two radiator fans turn round simultaneously.
The quantity of radiator fan is not that being limited to above-mentioned is among three embodiment, but takes all factors into consideration the factors such as heat radiation requirement, noise pollution, installation cost of electric food warmer, and it is comparatively preferred scheme that one or two radiator fan is installed.Radiator fan described in above-mentioned three embodiment all can adopt following mounting means: on radiator fan, offer through hole; The screw connecting hole corresponding with through hole is set on the radiator 5, wears screw between through hole and screw connecting hole radiator fan is fixed on the radiator 5; And the contact-making surface of radiator fan and radiator 5 is adjacent to each other, can improve the stability of radiator fan, and make metal heat sink 5 can better absorb the vibrating noise that radiator fan produces; Through hole can be designed as counterbore, and radiator fan is fixed on the radiator 5 through sunk screw, can play relaxation effect, avoids radiator fan the situation that screw drops to occur after use a period of time; Screw connecting hole also can be designed to counterbore, places beam in this counterbore, utilizes beam to absorb the vibration of screw junction, further reduces noise; Threaded insert also can be placed in screw connecting hole inside, comes further to improve the firmness that screw connects; Because of screw connecting mode is a prior art, the technical staff should be able to know through foregoing description and knows its mounting means, so not shown in the drawings.
With reference to Fig. 2, on electric_pan pedestal 3, be provided with some louvres 31, louvre 31 is corresponding with radiator fan 7 positions, distributes heat through the louvre on the base 3, reduces base 3 temperature, prevents that the bottom temperature rise from exceeding standard.
Need to prove: as shown in Figure 3, the coil panel assembly below described in the foregoing description is a relative position, generally is meant under the electric food warmer normal operating condition, in the position near coil panel assembly bottom.
Through explaining of technique scheme and accompanying drawing, the purpose of the utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in the accompanying drawing and the top specific embodiment.Anyly do not depart from the function of the utility model and the modification of structural principle all will be included in the scope of claims.
