Abstract
The utility model discloses an air curtain special for an elevator, belongs to the field of air adjusting and heating devices, and particularly relates to an improvement on the structure of the air curtain special for the elevator. By means of the air curtain special for the elevator, heating and air exchange can be conducted on the elevator, and hot air inside the elevator and cold air outside the elevator can be prevented from exchange. The air curtain comprises a shell with a draught fan, wherein connecting pieces with connecting holes are arranged on the two sides of the rear portion of the shell respectively. The air curtain is characterized in that a straight air outlet is formed in the side, close to the connecting pieces, of the bottom of the shell, a swing air outlet is formed in the side, away from the connecting pieces, of the bottom of the shell, a swing blade is arranged at the position of the swing air outlet, and heating elements are arranged in the straight air outlet and the swing air outlet respectively.
Description
Technical field
The utility model belongs to air conditioning, heating installation field, relates in particular to a kind of improvement of Special air curtain machine for elevator structure.
Background technology
Air curtain is the airflow that drives through-flow or centrifugal wind wheel to produce by high-speed electric expreess locomotive, forms the invisible door curtain of one side.Therefore, also claim wind curtain machine, air curtain, air curtain machine, air lock, air gate.
Air curtain is arranged on refrigeration, air-conditioning, dustproof, heat insulation tops, doorway such as market, theater, hotel, restaurant, conference hall, freezer, operating room and household, start this machine, the air of indoor and outdoor can be separated, play both easy access, can prevent again the cold and hot air exchange of indoor and outdoor, meanwhile, there is again effect dustproof, anti-pollution, anti-mosquito.Be widely used in electronics, instrument, pharmacy, food, Precision Machining, chemical industry, shoemaking and service, business etc. industry.
Existing Special air curtain machine for elevator only has an air outlet, therefore, only can play the effect that prevents the inside and outside cold and hot air exchange of elevator.But when in elevator, people is many, the air of elevator inside does not produce mobile, can cause people's discomfort.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of and can heat elevator, take a breath, and can stop the Special air curtain machine for elevator of the inside and outside cold and hot air exchange of elevator.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises the housing with blower fan, both sides, housing rear all arrange the brace with connecting hole, it is characterized in that: housing bottom is provided with straight wind outlet near a side of brace, housing bottom is provided with the outlet of pendulum wind away from a side of brace; Pendulum wind exit is provided with pendular impeller, in described straight wind outlet and the outlet of pendulum wind, is provided with heating element heater.
As a kind of preferred version, described heating element heater adopts PTC semiconductive ceramic element.
As another kind of preferred version, described blower fan adopts cross flow blower.
The utility model beneficial effect: when the utility model is installed, brace is secured by bolts in to elevator door top; By straight wind outlet is arranged to the side near brace, makes straight wind outlet towards elevator door place, thereby avoided the exchange of the inside and outside cold and hot air of elevator.
In addition, pendulum wind outlet of the present utility model is provided with pendular impeller, makes to put the wind formation swing that wind outlet blows out, and makes also rapid flow, the circulation of air of elevator inside, produces uncomfortable sensation while avoiding elevator insider many.
Heating element heater of the present utility model adopts PTC semiconductive ceramic element, and heating effect is good.
Blower fan of the present utility model adopts cross flow blower, and noise is low, volume is little, is applicable to being arranged on elevator.
Accompanying drawing explanation
Fig. 1 is upward view of the present utility model.
Fig. 2 is use state diagram of the present utility model.
In accompanying drawing, 1 is that brace, 2 is that blower fan, 3 is that housing, 4 is that pendulum wind outlet, 5 is that heating element heater, 6 is that pendular impeller, 7 is that straight wind outlet, 8 is elevator door.
The specific embodiment
The utility model comprises the housing 3 with blower fan 2, housing 3 both sides, rear all arrange the brace 1 with connecting hole, it is characterized in that: housing 3 bottoms are provided with straight wind outlet 7 near a side of brace 1, housing 3 bottoms are provided with pendulum wind outlet 4 away from a side of brace 1; Pendulum wind exports 4 places and is provided with pendular impeller 6, in described straight wind outlet 7 and pendulum wind outlet 4, is provided with heating element heater 5.
As a kind of preferred version, described heating element heater 5 adopts PTC semiconductive ceramic element.
As another kind of preferred version, described blower fan 2 adopts cross flow blower 2.
During installation, will by bolt, the brace 1 at the utility model housing 3 rears be fixed on to the top of elevator door 8; Start the utility model, straight wind outlet 7 wind that blow out can form air curtain at elevator door 8 places, stop that the inside and outside air of elevator carries out heat exchange; Pendulum wind outlet 4 can be blown in elevator, controls the trend of wind by pendular impeller 6, thereby improves circulation and the efficiency of heating surface of air in elevator.
Be understandable that, above about specific descriptions of the present utility model, only for being described, the utility model is not limited to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; As long as meet, use needs, all within protection domain of the present utility model.
