Abstract
A convertible airflow channel device used in a warmer at least comprises an air inlet channel and an exhaust channel and a blowing channel which are communicated with the air inlet channel, wherein a rotating blade driven by a synchronous motor is arranged between the exhaust channel and the blowing channel, and one end part of the rotating blade is positioned at an air inlet channel opening; travel switches matched with the end parts of the rotating blades are arranged at the upper end and the lower end of the air inlet channel opening; the novel air blower has the characteristics of simple structure, convenience in use, small size, low cost, capability of realizing mutual switching of air blowing and air exhausting, improvement on working efficiency and the like.
Description
Technical field
The utility model relates to and a kind ofly be exclusively used in the warmer convertible gas channel to realize blowing and exhaust device for switching.
Background technology
At present, in the warmer field, realize drying and the function primary structure of exhaust has: the one, adopt two motors and two wind wheels respectively, a blowing, another exhaust, the main shortcoming of this mode is that volume is big, the cost height; The 2nd, only with a motor and a wind wheel, this wind wheel is a Bidirection air vane, the positive and negative function that realizes blowing and exhaust that transfers by the control motor, the major defect of this kind mode is: efficient is low, air quantity is little, the rotating frequent starting electric current of motor is big, cause burning out of motor easily, shorten the service life of motor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide that a kind of volume is little, cost is low, easy to use and reliable, can realize smoothly drying and exhaust is switched mutually is used for the convertible gas channel device of warmer.Exhaust which comprises at least inlet channel and communicate with it and blowing passage are provided with the rotating vane that is driven by synchronous motor between described exhaust and the blowing passage, and an end of this rotating vane is positioned at the inlet channel mouth.
The two ends up and down of described inlet channel mouth are provided with the travel switch that the end with rotating vane matches.
The utility model belongs to a kind of improvement to prior art, and it has simple in structure, and is easy to use, and volume is little, and cost is low, can realize that blowing and exhaust switch characteristics such as increase work efficiency mutually.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is a function circuit schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, exhaust 2 and blowing 3 passages that the utility model includes inlet channel 1 at least and communicates with it, described exhaust 2 and drying is provided with the rotating vane 5 that is driven by synchronous motor 4 between 3 passages, an end of this rotating vane 5 is positioned on 1 mouthful of the inlet channel.The two ends up and down that this inlet channel is 1 mouthful are provided with the travel switch 6,7 that the end with rotating vane 5 matches.The two ends up and down that described inlet channel is 1 mouthful are the position of relative rotating vane, but be at least described travel switch 6,7 in opposite directions (up and down) corresponding and establish.
The utility model adopts 30 degree angle rotating vanes 5 of synchronous motor 4 and travel switch 6,7 controls, defines the function of blowing and exhaust respectively by two rotation stop places of rotating vane 5.
In conjunction with shown in Figure 2, start degassing function: power switch K1 closure, change-over switch K4 gets to the exhaust shelves, if the NC conducting of travel switch 7, then synchronous motor 4 work, the blade 5 that is fixed on the synchronous motor shaft rotates together, after blade 5 touches travel switch 7, the NO conducting of travel switch, synchronous motor 4 quits work, and the work of wind wheel motor M starts degassing function; On the contrary, power switch K1 closure, when change-over switch K4 gets to the exhaust shelves, if the not conducting of NC of travel switch 7, the then certain conducting of the NO of travel switch 7, the work of wind wheel motor M starts degassing function;
Start blowing function: power switch K1 closure, change-over switch K4 gets to the blowing shelves, if the NC conducting of travel switch 6, then synchronous motor 4 work, the blade 5 that is fixed on the synchronous motor shaft rotates together, after blade touches travel switch 6, the NO conducting of travel switch, synchronous motor 4 quits work, and the work of wind wheel motor M starts blowing function; On the contrary, power switch K1 closure, when change-over switch K4 gets to the blowing shelves, if the not conducting of NC of travel switch 6, the then certain conducting of the NO of travel switch 6, the work of wind wheel motor M starts blowing function; Because travel switch 6 and 8 is interlocks, so their NO has identical state with NC, travel switch 8 is used for controlling the connecting and disconnecting of PTC again.
