Abstract
The utility model discloses a bidirectional exhaust fan with heating exchange, which mainly includes an electromotor. A pair of fan leaf are respectively arranged at the two ends of the output axis of the motor, the outside of the electromotor is provided with an outside cover shell, two convection air ducts which are separated with each other and has a double screw thread shape are arranged between the outside cover shell and the electromotor shell, and each air duct only has a pair of fan leaf to communicate, each air duct are respectively provided with an air inlet and an air outlet; the clapboard between the two air ducts is made from the mental material with higher heating conductive efficiency. When use the bidirectional exhaust fan with the structure, because the clapboard between the two air ducts is made from the mental material with higher heating conductive efficiency, in such way, the air entering and the air discharging can make the heating exchange by the middle clapboard of the two air ducts, therefore, the process of the gas exchange can hardly influence the indoor temperature, as well as can hardly increase the consumption of the energy.
Description
Technical field
The utility model relates to a kind of ventilation fan.
Background technique
For ordinary family and office, people use common ventilation fan to come to take a breath to indoor usually.This ventilation fan relatively simple for structure mainly comprises a motor, at an end of motor output shaft one secondary flabellum is installed, and the outside also is coated with the plastic housing shell usually.During use, at first ventilation fan is installed in the through hole on the wall or other required place.When needs during to indoor air-changing, make motor get electric work, the flabellum of rotation just can directly be discharged indoor air outdoor, perhaps also can by a breathing pipe will be indoor air discharge outdoor, to reach the purpose that exchanges indoor air.Use the ventilation fan of above-mentioned conventional construction, its shortcoming is: one, under the situation of the summer of sweltering heat, indoor use air-conditioning, because the indoor and outdoor temperature difference is bigger, as the common ventilating fan of direct use to indoor air-changing, the refrigeration of room conditioning can be had influence on, and the consumption of the energy can be increased; Two, in the winter of cold, because the indoor and outdoor temperature difference is also bigger, use common ventilating fan to indoor air-changing, equally also can have influence on indoor air temperature, also can increase the consumption of the energy.
Summary of the invention
At the problems referred to above, can influence room temperature when the utility model will provide a kind of the ventilation hardly, have the dual direction ventilating fan of heat exchange.
For achieving the above object, the technical solution adopted in the utility model is: the described dual direction ventilating fan that has heat exchange, mainly comprise motor, two ends at the output shaft of motor are separately installed with a secondary flabellum, outer periphery at motor is equipped with an outer casing, is provided with two convection current air vents separate, two screw thread forms between outer casing and electric machine casing, and, each air vent only is connected with a secondary flabellum, and each air vent all is respectively arranged with intake grill and exhaust outlet; Dividing plate between two air vents is made by the higher metallic material of heat transfer efficiency.
The further technological scheme of the utility model is: be respectively arranged with a trim at the two ends of outer casing, each trim is provided with two separate ventilating holes, and a ventilating hole on trim is connected with the intake grill of an air vent and its another ventilating hole is connected with the exhaust outlet of another air vent.
The utility model has the advantages that: when using the dual direction ventilating fan of said structure, can be with the convection current air vent of two screw thread forms respectively as gas-entered passageway and outlet passageway, again owing to the dividing plate between two air vents is made by the higher metallic material of heat transfer efficiency, like this, air inlet and give vent to anger and just can carry out heat exchange by the intermediate clapboard of two air vents, therefore, just can influence indoor temperature hardly during ventilation, also just can increase the consumption of the energy hardly.
Description of drawings
Fig. 1 is the structural representation of dual direction ventilating fan described in the utility model.
Mode of execution
Below in conjunction with the drawings and specific embodiments technological scheme described in the utility model and working principle thereof and advantage are further described.
As shown in Figure 1, the dual direction ventilating fan that has heat exchange described in the utility model, mainly comprise motor 1, two ends at the output shaft of motor 1 are separately installed with a secondary flabellum 2 and 10, outer periphery at motor 1 is equipped with an outer casing 4, between the housing of outer casing 4 and motor 1, be provided with two convection current air vent A separate, two screw thread forms and B, and each air vent only is connected with a secondary flabellum---promptly: air vent A is connected with the flabellum 10 in left side, air vent B is connected with the flabellum 2 on right side; Each air vent all is respectively arranged with intake grill and exhaust outlet---and promptly: air vent A is provided with intake grill 9 and exhaust outlet 15, and air vent B is provided with intake grill 3 and exhaust outlet 11; Dividing plate 12 between two air vent A and the B is by the higher metallic material of heat transfer efficiency---becomes as aluminium or copper.In the present embodiment, be respectively arranged with a trim 8 and 5 at the two ends of outer casing 4, each trim is provided with two separate ventilating holes---and promptly: trim 8 is provided with ventilating hole 7 and 13, and trim 5 is provided with ventilating hole 6 and 14; And a ventilating hole 7 on the trim 8 is connected with the intake grill 9 of air vent A and its another ventilating hole 13 is connected with the exhaust outlet 11 of air vent B, and a ventilating hole 6 on the trim 5 is connected with the intake grill 3 of air vent B and its another ventilating hole 14 is connected with the exhaust outlet 15 of air vent A.
The working principle of the dual direction ventilating fan of said structure is as follows: at first above-mentioned ventilation fan can be installed in the through hole on the wall, in the present embodiment, suppose: the intake grill 9 of air vent A with outdoorly communicate, exhaust outlet 15 communicates with indoor, the exhaust outlet 11 of air vent B with outdoorly communicate, intake grill 3 communicates with indoor; When the ventilation fan with said structure be installed in indoor other required local time, connecting tube is realized above-mentioned assumed condition in addition.When indoor need the ventilation, starting electrical machinery 1, the flabellum 10 in left side will rotate simultaneously with the flabellum 2 on right side like this, therefore, the flabellum 10 in left side just is sent to air vent A from ventilating hole 7 and intake grill 9 with outdoor fresh air, at last from exhaust outlet 15 and ventilating hole 14 with outdoor fresh air conveying to indoor; Simultaneously, the flabellum 2 on right side just is sent to air vent B from ventilating hole 6 and intake grill 3 with indoor muddy air, from exhaust outlet 11 and ventilating hole 13 indoor muddy air is delivered to outdoorly at last, finally reaches in the switch room and the purpose of outdoor air.When the temperature difference of indoor and outdoors is big, the gas of indoor output and the gas of outdoor input just can carry out heat exchange by the intermediate clapboard 12 of two air vent A and B, like this, when outdoor air arrives when indoor by air vent A, its temperature just can reach or near room temperature.Therefore, use dual direction ventilating fan described in the utility model, to indoor the ventilation time, just can influence indoor temperature hardly, also just can increase the consumption of the energy hardly.
