Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and particularly relates to an air supply device with adjustable blade angles and an air conditioner. Background Art

[0002] The production workshop of a cigarette factory belongs to a large and tall space. At present, the air supply and return mode in the workshop is "upper supply and upper return", and one air handling unit is adopted, that is, one air conditioning box serves multiple workshops, and "one drags multiple" for temperature and humidity regulation. At present, in the variable air volume control of the cigarette factory air conditioner, manual air valves are mainly used for air volume distribution, and the air supply outlets are swirl air outlets. This results in that the air volume distribution cannot be adjusted in time according to the workshop requirements. At the same time, when the air volume is small, the swirl air outlets cause insufficient wind penetration force, and the processed air cannot be smoothly sent to the lower part of the workshop in the upper air supply mode, greatly reducing the temperature and humidity control ability of the combined air conditioner for the workshop and causing energy waste.

[0003] The demand for the air volume of the air conditioner is affected by factors such as the external environment of the workshop and the heat dissipation of the production equipment in the workshop. And rapid temperature and humidity control in the workshop is an essential requirement. How to achieve rapid and accurate air supply of the air conditioner is not available in the current cigarette factory air conditioner control. The change of the external environment causes the formation of uneven temperature and humidity areas inside the workshop.

[0004] Chinese Patent CN201310026930.X provides a temperature-controlled automatic adjustment swirl air supply outlet for an air conditioning system, which is used to supply air to a relatively enclosed space under the action of the air conditioning system, including a temperature control actuator, a gear transmission box, a guide vane transmission box, a guide vane group, a gear shaft, and a push-pull rod; after the temperature control actuator senses the temperature of the relatively enclosed space, it generates a horizontal push-pull force to push and pull the push-pull rod; the push-pull rod is connected to and pushes and pulls the gear transmission box; the gear transmission box is connected to and drives the gear shaft to rotate; the gear shaft is connected to and drives the guide vane transmission box to rotate; the vane transmission box is connected to and toggles the guide vane group to rotate. Its structure for toggling the guide vanes to rotate is relatively complex. By means of the temperature control actuator generating a horizontal push-pull force, the guide vanes are rotated through multiple-stage transmission, with low efficiency and poor reliability. In addition, in the specific scheme it provides, one section of the vane rotating shaft is connected to the air supply outlet housing, and the air supply outlet housing also needs to rotate with the vane, forming an unnecessary rotational load and wasting energy.

[0005] How to provide a better air supply device with adjustable blade angles to adjust the air supply flow pattern of the air conditioner and achieve rapid regulation for uneven temperature and humidity is a technical problem urgently to be solved in this field. Summary of the Utility Model

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0032] In the description of the present application, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In the present application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the case where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath" and "under" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0034] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0035] As Figures 1-4 , Embodiment 1 provides a air supply device with adjustable blade angles, including: a blade connector 1 that can rotate around its own axis; blades 2 evenly arranged circumferentially around the blade connector 1, and the blades 2 can rotate relative to the blade connector 1 to adjust the angle with the rotation plane of the blade connector 1; a hinge part 42 connected to the blades 2; an angle adjustment device, which includes a transmission rod 3 and a driving member 5. One end of the transmission rod 3 is hinged to the hinge part 42 and can make the blades 2 rotate relative to the blade connector 1, and the other end is hinged to the driving member 5.

[0036] As Figures 2-4 , in the air supply device with adjustable blade angles provided by this application, the included angle between the blade 2 and the rotation plane of the blade connecting member 1 is adjustable. The angle adjustment device forms a linkage mechanism with the blade 2 through the articulated transmission rod 3, so that the position and attitude of the transmission rod 3 have a definite corresponding relationship with the angle of the blade 2. Driving the transmission rod 3 by the driving member 5 can realize the adjustment of the angle of the blade 2. Due to the stability of the linkage mechanism, the transmission rod 3 also has a limiting and supporting effect on the blade 2. Moreover, the transmission rod 3 usually also has a relatively light mass and is suitable for being in tension, and is suitable for rotating with the blade 2. Therefore, this angle adjustment device is simple and reliable, easy to implement, and has a large adjustable range.

[0037] By adjusting the angle of the blade 2, this air supply device can provide air outlets with various flow patterns, so that the air outlet has different degrees of penetration ability and is suitable for different working conditions.

[0038] As Figure 3 , in this embodiment, the angle adjustment device includes a fitting connecting member 4. The fitting connecting member 4 includes a fitting portion 41 that fixedly fits the surface of the blade 2, and the hinge portion 42 is also provided on the fitting connecting member 4. Compared with directly hinging the blade 2 and the transmission rod 3, using the fitting connecting member 4 to indirectly hinge the blade 2 and the transmission rod 3 can make the blade 2 have better integrity, avoid the influence of gas turbulence caused by the irregular shape of the blade 2 on the air outlet effect, and reduce the processing difficulty of the blade 2.

[0039] In this embodiment, the fitting connecting member 4 is a rod, the fitting portion 41 is located on the side surface of the fitting connecting member 4, the hinge portion 42 is located at the end of the fitting connecting member 4 away from the fitting portion 41, and the length direction of the fitting connecting member 4 is parallel to the width direction of the blade 2. Since the angle adjustment mechanism of this application belongs to a linkage mechanism, setting the fitting connecting member 4 as a rod and making its length direction parallel to the width direction of the blade 2 is the simplest implementation form of the linkage mechanism, which is sufficient to meet the use requirements while having a relatively light weight, high adjustment efficiency, and easy to implement. In other embodiments, the fitting connecting member 4 can also be a sheet-like connecting member to increase the fitting area and enhance the fitting stability.

[0040] Considering the transmission characteristics of the linkage mechanism, in order to improve the transmission efficiency, avoid the dead point state formed by the transmission rod 3 and the fitting connecting member 4 from affecting the adjustment effect, simplify the movement of the driving part, and maintain a large adjustment range of the angle adjustment device, in this embodiment, the included angle range between the transmission rod 3 and the hinge portion 42 through the limiting member of the hinge is 20° to 170°, and the linkage transmission at this angle is relatively efficient.

[0041] The length of the transmission rod 3 should be greater than the distance from the hinge point of the transmission rod 3 and the blade 2 to the axis of rotation of the blade 2 relative to the blade connector 1. In this embodiment, the length of the transmission rod 3 is three times the length of the fitting connector 4. Preferably, the length of the transmission rod 3 is greater than or equal to three times the length of the fitting connector 4. The angle adjustment device with this length relationship has a higher adjustment efficiency.

[0042] As Figure 2 , in this embodiment, the driving member 5 includes a connecting ring 51, and the transmission rod 3 is connected to the connecting ring 51. The number of transmission rods 3 is the same as that of the blades 2, usually more. Setting the connecting ring 51 can facilitate the unified movement trajectory of the transmission rods 3, avoid driving each transmission rod separately, and reduce the complexity of the device.

[0043] As Figure 2 , in this embodiment, the connecting ring 51 is coaxial with the blade connector 1 and can approach or move away from each other. The distance between the connecting ring 51 and the blade connector 1 corresponds to different angular states of the blade 2. As Figures 1-2 , the driving member 5 further controls the connecting ring 51 to approach or move away from the blade connector 1 along the axis to adjust the angular state of the blade 2. In other embodiments, the connecting ring 51 can also adopt other motion forms to correspond to different angular states of the blade 2, such as rotating around the axis. Compared with other motion forms, the advantage of the translational motion of the connecting ring 51 along the axis of the blade connector 1 is that it is less affected by the rotation of the blade connector 1 and the blade 2 during the air supply operation.

[0044] As Figure 2 , in this embodiment, the driving member 5 includes a rack 52 connected to the connecting ring 51, a gear 53 meshing with the rack 52, and a power source 54 that is relatively fixed in distance from the blade connector 1 and drives the gear 53 to rotate. The power source 54 drives the gear 53 to rotate, which can drive the rack 52 to move up and down, so that the connecting ring 51 approaches or moves away from the blade connector 1. The gear transmission is relatively stable and reliable, with high precision and easy to implement, and is suitable for the driving member 5 of this application.

[0045] In this embodiment, the power source 54 is a synchronous motor. The synchronous motor is convenient to control and has a fast response, and is suitable as the power source 54 of this application.

[0046] Considering that temperature and humidity are the main parameters of the working conditions of this air supply device, in order to enable this air supply device to further have the function of adjusting the angle of the blade 2 according to the working conditions, a controller electrically connected to the synchronous motor is further included in this embodiment. The controller includes a temperature and humidity sensor unit.

[0047] Embodiment 2 provides an air conditioner, including the air supply device of Embodiment 1, including all its technical solutions, so it also has all its beneficial effects.

[0048] The content described above can be implemented alone or in various combinations, and these variant ways are all within the protection scope of the present utility model.
