Abstract
A connection structure of a microwave oven fan comprises a power circuit and a fan of a cooling fan. The fan of the cooling fan is connected into the power circuit, an alternating current (AC) fan is directly connected into the power circuit, or a direct current (DC) module is connected into the power circuit, and then the DC module is connected with a DC fan. The connection structure of the microwave oven fan performs an adding design based on the existing connection structure of the microwave oven fan, connects the DC module to the position of the connecting line of the power circuit, converts the AC to the DC through the DC module, then connects the DC which is output from the DC module to the DC fan to achieve the purpose of utilizing the DC fan in the power circuit. The microwave oven fan has the advantages of being capable of utilizing both the AC fan and the DC fan, being simple in structure and being practical and reliable.
Description
Technical field
The utility model relates to a kind of syndeton of microwave oven fan, the syndeton that particularly a kind of dc fan and AC blower fan can be general.
Background technology
Existing micro-wave oven generally all is to control its work by microcomputer.When micro-wave oven was worked, its inner electronic component will generate heat, if the heat of generation does not in time distribute, will burn electronic component, so the fan of heat transmission generally all has been installed at microwave oven internal.At present, the radiator fan of micro-wave oven on the market mostly is to use AC blower fan (magnetron and the transformer that are used for the cooled microwave stove), and the radiator fan that only has a small amount of micro-wave oven is the dc fan that uses.Because the driving power of dc fan is the DC power supplier that is provided or developed separately by computer board, so the syndeton that existing microwave oven fan adopts can't be used dc fan; If need to use the syndeton that just must redesign blower fan.Therefore, be necessary to make further improvements.
The utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, and can realize the syndeton of the microwave oven fan that AC blower fan and dc fan all can use, to overcome the deficiencies in the prior art part.
By the syndeton of a kind of microwave oven fan of this purpose design, comprise power circuit and be connected to the blower fan of the radiator fan in the circuit that its architectural feature is direct incoming transport blower fan in the described power circuit; Or accessing direct current (AC/DC) module in the power circuit, direct current (AC/DC) module is connected with dc fan again.
Comprise the first connecting line and the second connecting line in the described power circuit, the first connecting line directly is connected with direct current (AC/DC) module with the second connecting line, and direct current (AC/DC) module is connected with dc fan.
The first connecting line in the described power circuit be connected connecting line and directly be connected with AC blower fan.
Described direct current (AC/DC) module and dc fan is wholely set or minute be arranged.
The utility model is to increase design on the basis of the syndeton of existing microwave oven fan, in the connecting line place of power circuit access direct current (AC/DC) module, by this module alternating current is converted into direct current, to be connected on the dc fan from the direct current of direct current (AC/DC) module output again, thereby reach the purpose of in power circuit, using dc fan.This microwave oven fan both can use AC blower fan, can use dc fan again, and was simple in structure, practical reliable.
Description of drawings
Fig. 1 is the structural representation of access dc fan in the utility model one embodiment power circuit.
Fig. 2 is the structural representation of incoming transport blower fan in the embodiment power circuit.
Among the figure: 1 is the first connecting line, and 2 is the second connecting line, and 3 is direct current (AC/DC) module, and 4 is dc fan, and 5 is AC blower fan.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 2, a kind of syndeton of microwave oven fan comprises power circuit and is connected to the blower fan of the radiator fan in the circuit.The first connecting line 1 in the power circuit directly is connected with direct current (AC/DC) module 3 with the second connecting line 2, and direct current (AC/DC) module 3 is connected with dc fan 4.After with dc fan 4 access power circuits, start micro-wave oven, the first connecting line 1 and the second connecting line 2 two ends have 220V 50HZ(or 230V 50HZ) voltage, this moment, direct current (AC/DC) module 3 was converted into direct current with alternating current, again direct current is connected on the dc fan 4, thereby reaches the purpose of in power circuit, using dc fan 4.In addition, if need in power circuit, use AC blower fan 5, then can directly remove direct current (AC/DC) module 3, then with AC blower fan 5 access power circuits.At this moment, the first connecting line 1 that is connected with AC blower fan 5 and the second connecting line 2 two ends just have 220V50HZ(or 230V 50HZ) voltage, AC blower fan 5 is started working.
Claims (4)
1. the syndeton of a microwave oven fan comprises power circuit and is connected to the blower fan of the radiator fan in the circuit, it is characterized in that in the described power circuit directly incoming transport blower fan (5); Or access direct current AC/DC module (3) in the power circuit, direct current AC/DC module (3) is connected with dc fan (4) again.
2. the syndeton of microwave oven fan according to claim 1, it is characterized in that comprising in the described power circuit the first connecting line (1) and the second connecting line (2), the first connecting line (1) be connected connecting line (2) and directly be connected with direct current AC/DC module (3), direct current AC/DC module (3) is connected with dc fan (4).
3. the syndeton of microwave oven fan according to claim 2, it is characterized in that in the described power circuit the first connecting line (1) be connected connecting line (2) and directly be connected with AC blower fan (5).
4. the syndeton of each described microwave oven fan according to claim 1-3 is characterized in that described direct current AC/DC module (3) and dc fan (4) are wholely set or minute is arranged.
