Description

The combined type Natural wind convector

The utility model is about exhaust fan, especially about inciting somebody to action the convector of hot-air discharge within doors.

Generally in doors or be provided with cold air, fan or air-conditioning equipment in the factory, to reduce indoor temperature, it is more efficient that people and machine are worked under thermophilic.But cold air, fan or air-conditioning equipment all need electricity consumption, and under summer, power consumption increased suddenly, when meeting outage condition, its indoor temperature promptly rose gradually.Therefore adopt the Natural wind convector that starts the fan rotation with external natural wind and indoor mode of carrying out convection current.This Natural wind convector is located in the factory on the roof, needs indoor thermal current reach a scheduled volume, just begins and it can be started; If do not reach this scheduled volume, Natural wind convector can't start, and this moment is indoor promptly very sultry and make us uncomfortable.Or the house lived by other high building shelves, and natural wind is blown into, and then common convector is lack scope for their abilities, performs practically no function.Can set up the direct rotating manner of motor for this reason, but increase the load of motor idle running outward when this Natural wind convector is driven by the wind comes from, the anti-strength demand of external wind-force that makes strengthens, and can't blow this Natural wind convector and rotate under the gentle breeze state.Therefore, how to allow gentle breeze also can blow Natural wind convector and rotate generation convection current effect, can according to indoor temperature change generated in case whether this Natural wind convector be rotated automatically again, be present one big problem.

The purpose of the utility model is to provide a kind of combined type Natural wind convector, and it both can change with inner temperature of room and start, and can start with the natural wind convection type according to the actual airflow state again.And in the latter's operation process, the load when not having motor idle running.

The purpose of this utility model is achieved in that a kind of combined type Natural wind convector, and it comprises outer cover, fixed mount, motor and the central shaft with blade and change, it is characterized in that this change inner edge is provided with the rib that several have lug; The hinged setting of the rotor case of this motor promotes the activity template that this outer cover rotates; This activity template offsets with the lug of this change after with revolution perk outward.

The utility model is provided with by natural wind with by the motor two that temperature sensing device is controlled and overlaps separate start-up system, the effect of formation temperature regulating action.Because motor is its centrifugal force of mat by activity template disposed thereon outer to be stuck up or promotes outer cover toward interior applying and rotate or stop.There is not the bindiny mechanism that often engages between motor and outer cover, so when natural wind promoted the outer cover rotation, motor was not neither with having relative motion again between outer cover rotation and stator and rotor, thus the additional load (resistance) that does not have Yin Mada to cause, suitable breeze start-up.Under situations such as calm, no convection current, the motor force start is arranged again, and described two cover start-up systems can automatically switch again, so the utility model is a kind of desirable convector that is suitable for various ambient windstream conditions.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the exploded view of the utility model most preferred embodiment.
