Mechanism for adjusting wind direction in air duct

Technical Field

The utility model relates to the field of wind direction adjustment, in particular to a mechanism for adjusting wind direction in an air duct.

Background

An air duct refers to a passage that carries an air flow from one location to another (e.g., for heating, cooling, or ventilation). The air conditioning is to regulate and control the temperature, humidity, cleanliness, air flow speed and the like in a certain room or space, and provide enough fresh air, when the heat is obtained or lost in the room, the heat is taken out from the room or the heat is supplemented into the room, so that the heat entering and exiting the room is equal, namely the heat balance is achieved, and the room is improved to keep a certain temperature; or balancing the humidity in and out of the room to maintain a certain humidity in the room; or exhausting polluted air from the room while supplementing the same amount of outdoor clean air (treated or untreated), i.e. achieving air balance. For example, in winter, when the outdoor temperature is reduced, the heat transfer quantity of the room to the outside is increased, if the heat supply quantity to the room is not changed at this time, the heat loss quantity of the room is larger than the obtained heat quantity, the original balance state is destroyed, the indoor temperature is inevitably reduced, and the heat loss quantity of the room is reduced along with the reduction of the temperature; when the room temperature falls to a certain value, the heat loss amount and the heat gain amount of the room are equal, and a new balance is achieved, but at this time, the indoor state is changed, and the indoor state when the balance is automatically achieved often deviates from the state desired by people, so that air conditioning is required.

As shown in fig. 1, a mechanism for adjusting wind direction in an air duct according to an embodiment of the present application includes an air duct 1, a deflector, a rotating disc 8, a rotating shaft 7, and a back plate 6.

One end of the air duct 1 is provided with a first air outlet 12, the other end is provided with a second air outlet 13, and in addition, an air inlet 11 is further arranged in a direction perpendicular to a connecting line of the first air outlet 12 and the second air outlet 13. Typically, wind enters the duct 1 from the inlet 11 and exits from the first outlet 12. The purpose of this embodiment is to direct the wind away from the second air outlet 13 in some cases, so as to avoid the wind from exiting the first air outlet 12.

For this purpose, in the embodiment of the present application, a back plate 6 is installed in the duct 1. A rotating shaft 7 extends into the air duct 1 from the outside of the air duct 1, and the rotating shaft 7 simultaneously penetrates through the back plate 6 and can realize free rotation relative to the back plate 6 through a bearing and other elements, namely, the back plate 6 serves as a rotation supporting base of the rotating shaft 7. At this time, the rotating shaft 7 is perpendicular to the air inlet direction and the air outlet direction of the air duct 1.

The rotating disc 8 is connected to the end of the rotating shaft 7 located in the air duct 1. The deflector is mounted on the rotating disc 8, and rotates to guide the wind entering from the air inlet 11 to the first air outlet 12 or the second air outlet 13. Thus, under normal conditions, the guide plate conducts the channel between the air inlet 11 and the first air outlet 12 and seals the second air outlet 13, and the air entering from the air inlet 11 is guided out from the first air outlet 12. When the situation occurs, the flow guide plate is rotated through the rotating shaft 7, so that the flow guide plate is communicated with a channel between the air inlet 11 and the second air outlet 13 and seals the first air outlet 12, and the wind entering from the air inlet 11 cannot be guided out from the first air outlet 12 but can be guided out from the second air outlet 13, thereby changing and guiding the flow direction of the wind in the air duct 1, and finally reducing the loss of wind power.

In some embodiments, the baffle may comprise a web 9 and a flat plate. The connecting plate 9 is arranged parallel to the rotating disc 8, the connecting plate 9 is in a sector shape, and the end of the connecting plate 9 where the central angle is located is connected with the end of the rotating shaft 7 located in the air duct 1. The flat plate is perpendicular to the connecting plate 9, and the flat plate is connected to one end of the connecting plate 9 away from the rotating shaft 7. In this way, the air entering from the air inlet 11 can be led out from the first air outlet 12 by conducting the channel between the air inlet 11 and the first air outlet 12 through a flat plate and blocking the second air outlet 13; after the flat plate is rotated, the flat plate conducts the channel between the air inlet 11 and the second air outlet 13 and seals the first air outlet 12, so that the air entering from the air inlet 11 can be guided out from the second air outlet 13.

In other embodiments, the deflector may also be of another construction, for example comprising a connection plate 9, a first wind deflector 10 and a second wind deflector 2. The connecting plate 9 is still parallel to the rotating disc 8, and is in a substantially fan shape, and the end of the central angle of the connecting plate 9 is still connected with the end of the rotating shaft 7 located in the air duct 1. The first wind deflector 10 and the second wind deflector 2 are arranged at an obtuse angle and perpendicular to the connecting plate 9, and after one end of the first wind deflector 10 and one end of the second wind deflector 2 are connected, the two wind deflectors are simultaneously connected to one end of the connecting plate 9, which is far away from the rotating shaft 7. Compared with a flat plate form, the obtuse-angle type guide plate formed by the first wind deflector 10 and the second wind deflector 2 has larger guide space, can have better guiding property on the trend of wind, and can reduce disturbance generated in the wind steering process.

In order to facilitate rotating the rotating disc 8 and the deflector, embodiments of the present application may further include a gear disc 5, a spindle 4, a base plate 3, and a crank handle. The base plate 3 is installed inside the air duct 1 and is disposed at a certain distance from the back plate 6. The main shaft 4 extends into the air duct 1 from the outside of the air duct 1, and the main shaft 4 also penetrates through the base plate 3 and can realize relative free rotation with the base plate 3 through a bearing and other elements. The main shaft 4 is perpendicular to the air inlet direction and the air outlet direction of the air duct 1, that is, the main shaft 4 is parallel to the rotating shaft 7. The gear disc 5 is connected to the end part of the rotating shaft 7, which is positioned in the air duct 1, and the edge of the rotating disc 8 is provided with a gear to be meshed with the gear disc 5. The crank handle is connected to the end part of the main shaft 4, which is positioned outside the air duct 1. In this way, by rotating the crank, the deflector can be driven to rotate, for example, the transmission ratio between the gear disc 5 and the rotating disc 8 is set to be greater than 1, so that the deflector can be driven to rotate by the crank in a more labor-saving manner. The transmission ratio between the gear disc 5 and the rotating disc 8 can also be set to be less than 1 to more rapidly rotate the deflector by the crank. Of course, the transmission ratio between the gear wheel 5 and the rotating disk 8 can also be just equal to 1.

The handle and the spindle 4 may be detachably connected, for example, by sleeving, so that the handle can be stored in other places when the handle is not used, and the handle is prevented from occupying space all the time.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above-described preferred embodiments should not be construed as limiting the utility model, which is defined in the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
