The circuit board is also provided with an operating state indicator light. The utility model discloses the control switch that will be used for producing time delay control signal concatenates on the live wire, and installs in the conventional place of house, and time delay module only needs to connect live wire and zero line, and time delay control signal is produced by control switch's disconnection and closure, and this signal passes through the power cord transmission, need not set up control line transmission time delay control signal in addition again, need not change conventional house wiring rule, and the swift flexibility of whole installation, and need not increase the installation cost. The utility model has the characteristics of simple structure is reasonable, the flexible operation, cost of manufacture are low.
Description
Technical field
The utility model relates to the time delay module of a kind of ventilation fan, particularly a kind of ventilation fan.
Background technique
All have the time-delay guide line on the ventilation fan of existing band delay function, see accompanying drawing 1, the input end that is the delay circuit end comprises live wire L, zero line N and guide line 8, also have delay control switch K3 and power switch K2 in addition, delay control signal is produced by delay control switch K3, and transfers to ventilation fan by guide line 8.
The shortcoming that the ventilation fan of above-mentioned band delay function exists is as follows: ventilation fan is except having live wire L and zero line N, also need increase a guide line 8, home cabling rule with routine, promptly have only live wire and zero line inconsistent, user such as need use the then necessary rewiring of the ventilation fan of band delay function, installing guide line 8 of increase, cause installation cost higher, and, must in live wire 10, increase in addition a power switch K2 is installed in the use for avoiding this ventilation fan charged for a long time.
The model utility content
The purpose of this utility model aims to provide the time delay module of a kind of simple and reasonable, flexible operation, ventilation fan that fabricating cost is low, to overcome deficiency of the prior art.
Press the time delay module of a kind of ventilation fan of this purpose design, comprise and be arranged on the power input terminal that joins with power line on the circuit board, also be provided with motor output end that joins with the ventilation fan motor on the circuit board, power line comprises live wire and zero line, and its structure characteristic is to be serially connected with the control switch that is used to produce delay control signal in the live wire.
Also be provided with the operating condition tutorial light on the described circuit board.
The control switch that the utility model will be used to produce delay control signal is serially connected in live wire, and it is conventional local to be installed in household, time delay module only need connect live wire and zero line, delay control signal is produced with closed by the disconnection of control switch, and this signal transmits by power line, does not need to be provided with in addition guide line transmission delay control signal again, need not change conventional home cabling rule, whole erection is fast flexibly, and need not increase installation cost.
The utility model will be in the past power switch and delay control switch set be a control switch, delay control signal is produced with closed by the disconnection of control switch, has simple and reasonable, flexible operation, characteristics that fabricating cost is low.
Description of drawings
Fig. 1 is the time delay module schematic representation of the ventilation fan of existing band delay function.
Fig. 2 is the utility model one embodiment's a schematic representation.
Structural representation when Fig. 3 uses for the utility model.
Among the figure: 2 is power input terminal, and 3 is circuit board, and 4 is the operating condition tutorial light, and 5 is motor output end, and 6 is the ventilation fan motor, 8 is guide line, and L is a live wire, and N is a zero line, and K1 is a control switch, K2 is a power switch, and K3 is a delay control switch, and 10 is time delay module, and 20 is ventilation fan.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 2-Fig. 3, the time delay module of this ventilation fan, comprise and be arranged on the power input terminal 2 that joins with power line on the circuit board 3, also be provided with motor output end 5 that joins with ventilation fan motor 6 on the circuit board 3, power line comprises live wire L and zero line N, is serially connected with the control switch K1 that is used to produce delay control signal among the live wire L.Also be provided with operating condition tutorial light 4 on the circuit board 3.Whole time delay module 10 is installed on the ventilation fan 20.
In the present embodiment, string advances a control switch K1 among the live wire L, its lead-in wire rule is the same with conventional home cabling rule, operating condition tutorial light 4 can design and be welded on the case surface that circuit board PCB went up or led to ventilation fan 20,10 needs of time delay module connect live wire L and zero line N, delay control signal is produced with closed by the disconnection of control switch K1, and this signal transmits by power line, does not need to be provided with in addition guide line transmission delay control signal again.
Control switch K1 has substituted power switch and delay control switch in the past, and delay control signal is produced with closed by the disconnection of control switch K1.
The used in air exchange fan time delay module is at control switch K1 first after the closure, ventilation fan is in normal working, bright operating condition tutorial light, if the normal operation process breaks control switch K1 and closed once more control switch K1 then be defined as the control signal that starts time-delay in 3s, ventilation fan receives the power supply that starts time-delay closing ventilation fan motor behind this signal, after finishing, time-delay then enters holding state, bright standby indicating lamp, disconnect control switch K1, do not need to start by other guide line input again the control signal of time-delay.Do not need again the then whole dead electricity of ventilation fan of closure, play the power supply control action.
In the present embodiment, no matter ventilation fan is in delay working state or holding state, no matter how long disconnects control switch K1, and in the 3s or beyond the 3s, when closed control switch K1 once more, ventilation fan then returns normal working automatically.
Working principle of the present utility model is: closed control switch K1, time delay module powers on, the controller output signal of ventilation fan is by the ventilation fan proper functioning, and bright operating condition tutorial light, start time-delay as need, disconnect control switch K1, the complete machine power down, but circuit board makes not power down of controller and make it keep having disconnected and detect civil power at the moment more than work 3s, if control switch K1 is in 3s once more after the closure, complete machine re-powers, it is closed that controller detects civil power, and promptly controller does not detect civil power disconnection and closed once more under the situation of power down in 3s, is to start delay control signal with this procedure definition then, ventilation fan enters the delay working state, bright delay working status indicator lamp, controller cut off motor power, bright standby indicating lamp after time-delay finished.
Ventilation fan is in delay working or holding state, if controller detects the civil power disconnection and is closed once more in 3s, then output signal makes the ventilation fan proper functioning, bright normal operating condition tutorial light, perhaps no matter ventilation fan is in normal working, delay working state or holding state, and control switch disconnects the enough time so that the controller power down, again behind the closed control switch, ventilation fan re-powers, and makes the ventilation fan proper functioning after controller resets, bright proper functioning tutorial light.
