Abstract
The utility model belongs to the daily electrical appliance, and relates to an air flow exhaust fan for indoor air displacement, in particular to an air flow exhaust fan for heating indoor air flow in winter, which comprises a shell body (2), an exhaust fan (3) and a control switch (5). The exhaust fan (3) and the control switch (5) are connected with the inside of the shell body (2). The air flow exhaust fan is characterized in that the shell body (2) is fixed on a window body or wall body (1); the exhaust fan (3) is fixedly arranged on the outer side of the shell body (2); an electric heating unit (4) is fixedly arranged on the inner side of the shell body (2); and the electric heating unit (4) is electrically connected with the exhaust fan (3) and the control switch (5). The utility model can be used as a normal air flow exhaust fan in summer and transitional seasons. When the outdoor temperature is lowered, the utility model can heat the air flow, improve the temperature of the air flow, and enhance the quality of the indoor air in accordance with personal habits. Simultaneously, the utility model can not cause significant fluctuation to the indoor temperature, thereby satisfying the comfort requirements of people.
Description
Technical field
The utility model belongs to daily-use electrical appliance, relates to a kind of exhaust fan that send of room air displacement, particularly can be used for the exhaust fan that send of indoor heating air-supply in winter.
Background technology
At present indoor air-changing be mainly that machinery gives, air draft or the gravity-flow ventilation of windowing.No matter adopt which kind of mode, indoor EAT is always identical with outdoor temperature, when winter, outside air temperature was low, causes indoor air temperature to reduce, and influences the indoor occupant quality of life.
Summary of the invention
The purpose of this utility model provides a kind of exhaust fan that send that can be used for indoor heating air-supply in winter, so that in summer and excessive season, it uses with normally to send exhaust fan identical, when outside air temperature reduces, can be according to personal habits, the heating air-supply, improve wind pushing temperature, improve IAQ, can not make indoor temperature that big fluctuation takes place simultaneously, satisfy the requirement of personnel's comfortableness.
The purpose of this utility model is to realize like this, the exhaust fan that send that can be used for indoor heating air-supply in winter, comprise housing, be connected exhaust fan and gauge tap in the housing, it is characterized in that: housing is fixed on forms or the body of wall, hull outside is exhaust fan fixedly, the inboard fixedly electric heating unit of housing, electric heating unit is electrically connected with gauge tap with exhaust fan.
Described electric heating unit is an electric heating tube.
Described gauge tap has air draft and two gears of air-supply.
The course of work of the present utility model and advantage:
Send the exhaust fan indoor to be equipped with electric air heater existing, when outside air temperature is low, can open electric air heater, improve wind pushing temperature, reduce the fluctuation of the indoor air temperature that causes owing to air-supply to indoor air-supply.Send exhaust fan to establish the third gear gauge tap: exhaust, air-supply, heating air-supply, the purpose of heating and air-supply interlock is to open electric air heater under the situation that prevents from not blow, and causes that air heater is overheated.
Characteristics of the present utility model are: simple, practical, all component all has ripe accessory; Easy to make, heating air-supply, for improve winter IAQ and comfort level very big Practical significance is arranged, indirect raising quality of life.
Description of drawings
Below in conjunction with example figure the utility model is described further.
Fig. 1 is the example structure schematic diagram;
Fig. 2 is the exhaust fan side view among Fig. 1.
Among the figure: 1, forms or body of wall; 2, housing; 3, exhaust fan; 4, electric heating unit; 5, gauge tap.
The specific embodiment
As shown in Figure 1, comprise housing 2, be connected exhaust fan 3 and gauge tap 5 in the housing 2, housing 2 is fixed on forms or the body of wall 1.
As shown in Figure 2, housing 2 outsides are exhaust fan 3 fixedly, housing 2 inboard fixedly electric heating units 4, and electric heating unit 4 is electrically connected with gauge tap 5 with exhaust fan 3.Gauge tap 5 has air draft and two gears of air-supply.Electric heating unit 4 is an electric heating tube.Send the exhaust fan indoor that electric air heater is installed.In summer and excessive season, normal air-supply or the air draft switch opened only send exhaust fan 1 work, carries out indoor air-supply or air draft.When outside air temperature reduces, can open heating air-supply switch according to personal habits, this moment electric air heater and send exhaust fan 1 to work simultaneously, the heating air-supply improves wind pushing temperature, guarantee that indoor temperature big fluctuation can not take place, satisfy the comfortableness requirement of indoor occupant.Electric heating unit 4 satisfies the insulating requirements of civilian equipment.Power supply: 220V/50HZ, power: 300W.With the air-supply linkage work.
Claims (3)
