For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of new blower fan, comprise motor, heat exchanger, heater, for detect outdoor environment temperature temperature-detecting device and when outdoor environment temperature is lower than the controller controlling described heater work during temperature threshold, described controller is all electrically connected with described temperature-detecting device and described heater, one end of described heat exchanger is connected with described motor, and the other end is connected with described heater.
Preferably, above-mentioned new blower fan also comprises the leeway switch whether opened for detecting described motor, and described controller can control described heater work when described motor is opened, and described leeway switch is electrically connected with described controller.
Preferably, described heater is specially electrical heating wire.
The utility model also provides a kind of air-conditioning, comprises the new blower fan described in above-mentioned any one.
Preferably, above-mentioned air-conditioning also comprises outdoor unit and the airduct for flowing into described new blower fan for outdoor air, and described outdoor unit is connected with described new blower fan.
New blower fan provided by the utility model, comprise motor, heat exchanger, heater, for detect outdoor environment temperature temperature-detecting device and when outdoor environment temperature is lower than the controller controlling described heater work during temperature threshold, described controller is all electrically connected with described temperature-detecting device and described heater, one end of described heat exchanger is connected with described motor, and the other end is connected with described heater.This new blower fan utilizes described temperature-detecting device to detect outdoor environment temperature, when outdoor environment temperature is lower than temperature threshold, described controller just controls described heater and starts working, for this new blower fan provides auxiliary heating, to improve the range of operation of this new blower fan, ensure, when outdoor environment temperature is lower, can normally work, for indoor provide enough new wind, meet the instructions for use of most area.
In a preferred embodiment, new blower fan provided by the utility model also comprises the leeway switch whether opened for detecting described motor, described controller can control described heater work when described motor is opened, and described leeway switch is electrically connected with described controller.Arranging of described leeway switch can ensure when described motor is opened, just can start described heater, avoid when described motor break down cannot work time, described heater starting causes this new blower interior temperature too high, cause damage, also can cause the wasting of resources.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of detailed description of the invention of new blower fan provided by the utility model.
Detailed description of the invention
Core of the present utility model is to provide a kind of new blower fan, and the range of operation of this new blower fan is wide, can meet the new wind demand of most area.Another core of the present utility model is to provide a kind of air-conditioning comprising above-mentioned new blower fan.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of a kind of detailed description of the invention of new blower fan provided by the utility model.
In this embodiment, new blower fan comprise motor 1, heat exchanger 2, heater 3, for the temperature-detecting device that detects outdoor environment temperature and the controller worked lower than control heater during temperature threshold 3 when outdoor environment temperature, controller is all electrically connected with temperature-detecting device and heater 3, one end of heat exchanger 2 is connected with motor 1, and the other end is connected with heater 3.This new blower fan utilizes temperature-detecting device to detect outdoor environment temperature, when outdoor environment temperature is lower than temperature threshold, controller just control heater 3 is started working, for this new blower fan provides auxiliary heating, to improve the range of operation of this new blower fan, ensure, when outdoor environment temperature is lower, can normally work, for indoor provide enough new wind, meet the instructions for use of most area.Here it should be noted that, the size of motor 1 can be selected according to required air force.
Further, the new blower fan that the present embodiment provides can also comprise the leeway switch 4 whether opened for detecting motor 1, and controller can work by control heater 3 when motor 1 is opened, and leeway switch 4 is electrically connected with controller.Leeway switch 4 is mainly connected on this Fresh air handling units to be had on the position of wind flow, and when leeway switch 4 has detected wind flow, when namely motor 1 is started working, leeway switch 4 closes.Controller, under the prerequisite of outdoor environment temperature lower than temperature threshold, detects that leeway switch 4 is closed, just can work by trigger heater 3, for heat exchanger 2 provides heat.Arranging of leeway switch 4 can ensure, when motor 1 is opened, just can start heater 3, avoid when motor 1 break down cannot work time, heater 3 start cause this new blower interior temperature too high, cause damage, also can cause the wasting of resources.
