Description
Technical field
The utility model belongs to small household appliances field, kitchen, relates in particular to a kind of electromagnetic oven heat radiation structure.
Background technology
Existing electromagnetic oven is when work, and itself does not produce naked light, and the heat that pan is produced in heating process then can be transmitted to structures such as drum under the body of heater or control circuit, and simultaneously, the IGBT structure of control circuit also can be sent a large amount of heat when work.In order to guarantee the operate as normal of electromagnetic oven, these are created in when the interior caloric requirement of body of heater is inhaled and discharge.For this reason, electromagnetic oven is typically provided with fan and inlet and outlet, and traditional electromagnetic oven only uses a fan, at the electromagnetic oven lower surface air inlet is set, and sets out the air port at the electromagnetic oven rear wall.Coil panel and control circuit then are arranged in the top of fan.During its work, fan blows to the control circuit and the coil panel of top after sucking wind, flow out through air outlet again.In order to fit into the good air draught effect in air port, this electromagnetic oven must be provided with the footing of certain altitude at lower surface, can produce certain space when allowing electromagnetic oven place in order to the suction air.So the height of its electromagnetic oven is inevitable higher, integral body is comparatively heavy.For better heat radiation, in traditional electromagnetic oven, coil panel and control circuit on same plane, are not arranged in the body of heater intricately.Therefore, also cause the electromagnetic oven height higher, whole comparatively heavy shortcoming.
Traditional electromagnetic oven all is to adopt a fan to dispel the heat, and a fan should dispel the heat simultaneously to the IGBT on coil panel and the control circuit, and the volume of fan need be done greatlyyer, and it is very fast that rotating speed is wanted, and therefore the noise that produces is also bigger.Also have the gap before coil panel and the control circuit, when same fan dispelled the heat at two places, inhaled air can not all be used for heat radiation, made the utilization rate of fan reduce.
The utility model content
The essential technique problem that the utility model is intended to solve be to provide a kind of air channel rationally, the high electromagnetic oven of radiator fan utilization rate.
At above essential technique problem, the corresponding technical solution scheme of the utility model is:
A kind of cooker fan and air channel structure, comprise the shell that constitutes furnace chamber, place the fan that is electrically connected mutually, coil panel and control circuit in the described furnace chamber, described shell is provided with air inlet and air outlet, it is characterized in that described fan is at least two, the sidewall of described shell is or/and diapire is provided with air inlet.As most preferably state of the present utility model, described fan is 2.Fan is during less than 2, and turnover wind effect is bad; Fan also can be realized the purpose of this utility model during greater than 2, but that the shortcoming that number is brought too much is a noise is bigger.
As the best preferential treatment state of the utility model, described fan is 2, and the described coil panel of one of them fan subtend carries out work, and another fan subtend control circuit carries out work, and the air inlet of 2 fans is positioned at the sidepiece of described shell.In the work of electromagnetic oven, the IGBT structure that main two parts of generating heat are coil panel and control circuit.Be directed to this, coil panel and control circuit respectively set up a fan to carry out heat radiation work pointedly, and the utilization rate of its fan has significantly radiating effect because of specific aim improves greatly.
Described 2 fans all are positioned at the same sidepiece of described shell.Such advantage is, its air inlet is concentrated, and coil panel and control circuit also can dispel the heat in the time of can being arranged on relative nearer position effectively.When fan only was located at a side, air outlet can be arranged at other three sidepieces of electromagnetic oven, and the circulation in air channel is big, good heat dissipation effect.
Described 2 fans can be arranged on the different sidepiece of electromagnetic oven according to the concrete structure of coil panel or control circuit.Its air outlet can be the same sidepiece of electromagnetic oven, also can different sidepieces for correspondence on.The turnover wind structure of many sidepieces, its air channel structure is better, and radiating rate is also fast.
As another kind of mode of the present utility model, described fan is 2, and the air inlet of one of them fan is positioned at the sidepiece of described shell, and the air inlet of another fan is positioned at the bottom of described shell.Coil panel and control circuit all are the bigger structures of volume, adopt the bottom air-out, can be directly at coil panel or the heat radiation of control circuit large tracts of land behind the air intake.
Further, described furnace chamber inner bottom part also is provided with thermal insulation layer, and described thermal insulation layer is bakelite or mica sheet or aluminium flake.In the utility model, be preferably mica sheet.When heat distributes under the untimely situation, mica sheet intercepts a large amount of heats and conducts to shell, avoids shell because of the generation of situations such as overheated modification that takes place or burning, has guaranteed security of the present utility model.
Compared with prior art, the beneficial effects of the utility model are: structural safety, air channel are rationally, the radiator fan utilization rate is high.
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Description of drawings
Fig. 1 is the schematic top plan view of the utility model embodiment.
The specific embodiment
As shown in Figure 1, cooker fan of the present utility model and air channel structure, comprise the shell 1 that constitutes furnace chamber, place the fan that is electrically connected mutually 2, coil panel 3 and control circuit 4 in the described furnace chamber, shell 1 is provided with air inlet and air outlet, wherein, fan 2 is at least two, and the sidewall of shell 1 is or/and diapire is provided with air inlet.
As the most preferably state of present embodiment, fan 2 is two.Because fan 2 is during less than two, turnover wind effect is bad; Fan 2 also can be realized the purpose of this utility model during greater than two, but that the shortcoming that number is brought too much is a noise is bigger.
