Description

A kind of DC fan circuit of low standby power loss
Technical field
The utility model relates to a kind of DC fan circuit, in particular a kind of DC fan circuit of low standby power loss.
Background technology
In recent years, because household DC fan has the advantages such as efficiency is high, noise is little, start in domestic environments popularization and application.Power consumption when traditional DC fan is in order to reduce standby, generally a hard switching (as triode or mos pipe etc.) is set on the current supply circuit of DC fan, as shown in Figure 1, the effect of hard switching is exactly the standby signal sent according to control circuit, cut off the loop of DC fan motor and power supply, DC fan is quit work.Traditional this DC fan circuit, just because of the existence of this hard switching, adds cost, simultaneously because hard switching generates heat in the course of the work, reduces the reliability of DC fan circuit working.
Therefore, prior art has yet to be improved and developed.
Utility model content
The purpose of this utility model is the DC fan circuit providing a kind of low standby power loss, is intended to solve traditional DC fan circuit and adopts hard switching and cause circuit cost high, the technical problem of functional reliability difference.
The technical solution of the utility model is as follows: a kind of DC fan circuit of low standby power loss, the fan electromotor comprising DC power supply, the control panel be connected with DC power supply and be connected with control panel, wherein, described DC power supply directly connects fan electromotor, described control panel connects DC power supply, described control panel is provided with the standby button reducing DC power output voltage.
The DC fan circuit of described low standby power loss, wherein, described control panel inside is provided with level generating circuit, and described standby button connects level generating circuit.
The beneficial effects of the utility model: the utility model is by directly connecting fan electromotor (not arranging hard switching between DC power supply and fan electromotor) by DC power supply, control panel connects DC power supply, when pressing the standby button of control panel, control panel receives standby signal, transmit control signal to DC power supply simultaneously, reduce the output voltage of DC power supply, thus reduce the stand-by power consumption of DC fan circuit.The utility model circuit structure is simple, without the need to using the electronic component such as triode, mos pipe as hard switching, reduces the cost of DC fan.Utility model works is stablized simultaneously, and do not generate heat, functional reliability is high, is applicable to applying.
Accompanying drawing explanation
Fig. 1 is the module map of traditional DC fan circuit.
Fig. 2 is the module map of the DC fan circuit of the utility model low standby power loss.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, clearly, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
The utility model discloses a kind of DC fan circuit of low standby power loss, as shown in Figure 2, the fan electromotor comprising DC power supply, the control panel be connected with DC power supply and be connected with control panel, concrete, DC power supply directly connects fan electromotor, control panel connects DC power supply, control panel is provided with the standby button reducing DC power output voltage.
In a preferred embodiment, control panel inside is provided with level generating circuit, and standby button connects level generating circuit.Concrete, standby button can as of this level generating circuit operating switch, and when pressing standby button, level generating circuit connection work, produces one and represent that DC fan enters the level signal (high level or low level) of standby mode.This level signal is sent to DC power supply by control panel, utilizes the PWM function of traditional DC power supply, realizes the effect of the output voltage reducing DC power supply, thus reduces the stand-by power consumption of whole DC fan circuit.
The utility model provides a kind of Novel DC fan circuit, this circuit not only ensure that the normal work of DC fan, realize simultaneously DC fan standby time low-power consumption, compared to the circuit using hard switching, its production cost lower (each DC fan circuit has probably saved 1-2 unit), work is not generated heat, and reliability is high.
What deserves to be explained is, control panel can adopt traditional fan governor, this fan governor can produce standby signal (i.e. level signal) according to the operation of user, and DC power supply self has PWM function, can regulate (reduction) output voltage according to level signal.Under normal circumstances, the operating voltage range of control panel is 6V-28V, and the normal working voltage of fan electromotor is about 24V, therefore, after DC power supply receives level signal, can reduce the voltage to 8V-10V.In practical application, only need to reduce the voltage to 10V, the stand-by power consumption of DC fan can reach European standard.
The utility model circuit structure is simple, without the need to using the electronic component such as triode, mos pipe as hard switching, reduces the cost of DC fan.Utility model works is stablized simultaneously, and do not generate heat, functional reliability is high, is applicable to applying.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection range that all should belong to the utility model claims.
