Description
Technical Field
[0001] The utility model relates to the technical field of air conditioning device accessories, in particular to an adjustable two-speed air conditioning diffuser. Background Art
[0002] Diffuser is one of the important components in the central air conditioning system. It is usually installed at the air outlet of the central air conditioner so that the air supplied by the central air conditioner can be evenly diffused indoors.
[0003] Conventional diffusers are composed of multiple blades arranged at an angle, which are fixed together by connecting rods. The wind direction of most diffusers is fixed and cannot be flexibly adjusted. This may lead to less than ideal indoor air flow distribution under different seasonal conditions. For example, when the air supply airflow is flat and attached, the cold air supply in summer can create a more comfortable indoor temperature by taking advantage of the sinking characteristics of cold air, while when the warm air is supplied in winter, the warm air will accumulate in the top space for a long time due to its small specific gravity, resulting in uneven indoor heating effect and poor comfort.
[0004] There are many electric adjustable diffusers in the prior art, which can adjust the air supply angle well, but the system is complex, requires power, and has high cost, which is not suitable for widespread use. CN201510651849.X once disclosed a new type of adjustable diffuser, which can be adjusted manually, but it still has the defects of more components and more complex structure. But in fact, most central air conditioners are used in winter and summer, so the adjustment of diffuser blades actually only needs to consider the air supply requirements of winter and summer working conditions. Therefore, if a simpler air conditioner diffuser that can be switched and controlled for two different working conditions in winter and summer can be designed, it can meet the use needs of most central air conditioners. Utility Model Content
[0005] In view of the deficiencies of the above-mentioned prior art, the technical problem to be solved by the utility model is: how to provide an adjustable two-speed air-conditioning diffuser with a simple structure, convenient adjustment, and switchable control for two different working conditions in winter and summer, so as to meet the use requirements of most central air conditioners.
[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0007] An adjustable two-speed air conditioner diffuser comprises an overall U-shaped wall panel for connecting to an air outlet of an air conditioner, an air outlet is formed inside the wall panel, an X-shaped fixing frame is arranged along the diagonal line inside the air outlet, and diffusers are arranged at intervals in four air outlet areas formed by the fixing frame, and both ends of the diffusers are rotatably connected to the fixing frame. It is characterized in that the middle parts of the diffusers in the four air outlet areas are each rotatably connected to a connecting rod, the inner end of each connecting rod is rotatably connected to the outer end of a transmission rod, the inner end of the transmission rod is rotatably connected to the execution end of a pressing mechanism, the pressing mechanism is axially installed at the middle position of the fixing frame, and the execution end of the pressing mechanism can be positioned at two positions in the front and rear of the axial direction.
[0008] In this way, when working, through the pressing mechanism, the actuator end can be positioned at two positions in the front and rear of the axis. The forward and backward movement of the actuator end can drive the transmission rod to pull the connecting rod, and then pulling the connecting rod can drive the two ends of the diffuser to rotate on the fixed frame. In this way, the two-speed adjustment of the rotation position of the diffuser is realized, so that it can realize switching control for two different working conditions in winter and summer. In winter, the air supply direction can be concentrated outward, so that the warm air is more concentrated to the working area, reducing air heat floating. In summer, the angle of the diffuser can be changed to ensure that the cold air is attached to a large extent. Then, the cold air passing through the diffuser first reaches the top of the room (ceiling air outlet situation) or around the wall (wall air outlet situation), so that the cold air is evenly distributed in the entire space, avoiding the cold air blowing directly to the working area, which is easy to cause air conditioning cold.
[0009] Furthermore, a U-shaped tuyere frame is connected inside the wall panel, the tuyere is formed inside the tuyere frame, and the end of the fixing frame is fixed on the tuyere frame.
[0010] This makes it easier to install and fix the fixing bracket.
[0011] Furthermore, both ends of the diffuser are connected to the fixing frame via a rotating shaft and a bearing installed at the middle position of the end along the length direction of the diffuser.
[0012] This makes it easier to adjust the rotation of the diffuser.
[0013] Furthermore, the connecting rod and one side of the middle portion of the diffuser plate are rotatably connected.
[0014] In this way, the connecting rod can better drive the diffuser to rotate.
[0015] Furthermore, a groove is arranged on one side surface of the middle part of the diffuser, and the connecting rod is movably installed in the groove and is rotatably connected through rotating shafts on both sides and the side walls of the groove.
[0016] In this way, the connecting rod can better drive the diffuser to rotate.
[0017] Furthermore, the pressing mechanism includes a pressure-applying member, a pressure-receiving member and a mounting tube, each of which is cylindrical and coaxially arranged. The mounting tube is mounted in a mounting hole in the middle position of the fixing frame, and the inner surface of the mounting tube protrudes inward to form a circumferential limit strip arranged along the axial direction; one end of the pressure-applying member is an extrusion end located outside the mounting tube, and the other end is a pressure-applying end fitted in the mounting tube, and the outer surface of the pressure-applying member is provided with a circumferential limit groove and a circumferential limit strip for sliding fit to achieve circumferential limit; one end of the pressure-receiving member is an execution end located outside the mounting tube, and the other end is a pressure-receiving end fitted in the mounting tube, and the execution end and the pressure-receiving end are rotatably arranged relative to each other; the pressure end end of the pressure-applying member and the pressure end end of the pressure-receiving member are each provided with a circle of triangles The convex teeth of the pressure-bearing member are formed with evenly spaced deep tooth grooves and shallow tooth grooves between the convex teeth at the pressure-bearing end of the pressure-bearing member, the width of the deep tooth groove and the shallow tooth groove is greater than or equal to the width of the circumferential limit strip, and the bottom of the deep tooth groove and the shallow tooth groove and the end of the circumferential limit strip facing one end of the pressure-bearing member are all inclined surfaces inclined in the same direction; a compression spring is also sleeved on the outside of the pressure-bearing member, and the compression spring acts between the pressure-bearing member and the mounting tube and applies pressure to the pressure-applying member in the direction of the pressure-applying member; when the deep tooth groove of the pressure-bearing end of the pressure-bearing member is limited to the circumferential limit strip, the convex tooth surface that the extrusion end of the pressure-applying member can fit with the pressure-bearing end of the pressure-applying member is an inclined surface in the same direction as the bottom of the deep tooth groove, and after fitting, the tooth tips of the convex teeth at both ends are each separated from the tooth roots of the convex teeth at the other end by a distance.
[0018] In this way, the pressure-bearing member abuts against the circumferential limit strip in the installation tube under the action of the compression spring. By simply pressing the extrusion end of the pressure-applying member, the pressure-bearing member can be controlled to switch between the deep tooth groove and the circumferential limit strip abutment and the shallow tooth groove and the circumferential limit strip abutment, thereby realizing the switching of the pressure-bearing member between two different positions in the axial direction. Because when the deep tooth groove of the pressure-bearing end of the pressure-bearing member abuts against the circumferential limit strip, the convex tooth surface that the extrusion end of the pressure-applying member can fit with the pressure-bearing end of the pressure-bearing member is an inclined surface in the same direction as the bottom of the deep tooth groove, and after fitting, the tooth tips of the convex teeth at both ends are each at a distance from the tooth roots of the convex teeth at the other end, and are not meshed in place. Therefore, during the switching control, when the pressure-bearing member is pushed out of the circumferential limit strip limit by the extrusion of the convex teeth of the pressure-applying member, the extrusion end of the pressure-applying member can further mesh with the convex teeth of the pressure-bearing end of the pressure-bearing member, thereby pushing the pressure-bearing end of the pressure-bearing member to rotate circumferentially by a certain angle. In this way, after the force of the pressure member is canceled, the pressure-receiving end that has rotated a certain angle under the reset action of the compression spring can switch between the deep tooth groove and the shallow tooth groove to achieve abutment with the circumferential limit strip. Then, the switching control of the two states is achieved by the extrusion of the pressure member. It is very convenient and fast, and the structure is ingenious and feasible.
[0019] In summary, the utility model can realize switching control of the air outlet angle according to two different working conditions in winter and summer, has the advantages of simple structure and convenient adjustment, and can meet the use requirements of most central air conditioners.

[0027] The utility model is further described in detail below in conjunction with specific implementation methods.
[0028] Best practice: See Figure 1-Figure 7 As shown, an adjustable two-speed air-conditioning diffuser comprises an overall U-shaped wall panel 1 for connecting to an air outlet of an air conditioner, an air outlet is formed inside the wall panel, an X-shaped fixing frame 3 is arranged along the diagonal line inside the air outlet, four air outlet areas formed by the fixing frame 3 are respectively arranged with diffusers 4 arranged at intervals, and both ends of the diffusers 4 are rotatably connected to the fixing frame 3, wherein the middle parts of the diffusers 4 in the four air outlet areas are respectively rotatably connected to a connecting rod 5, the inner ends of the connecting rods 5 are respectively rotatably connected to the outer ends of a transmission rod 6, the inner ends of the transmission rods 6 are rotatably connected to the execution end of a pressing mechanism, the pressing mechanism is axially installed at the middle position of the fixing frame 3, and the execution end of the pressing mechanism can be positioned at two positions in the front and rear of the axial direction.
[0029] Thus, see Figure 6 and Figure 7When working, through the pressing mechanism, the actuator end can be positioned at two positions in the front and rear of the axis. The forward and backward movement of the actuator end can drive the transmission rod to pull the connecting rod, and then pulling the connecting rod can drive the two ends of the diffuser to rotate on the fixed frame. In this way, the two-speed adjustment of the rotation position of the diffuser is realized, so that it can realize switching control for two different working conditions in winter and summer. In winter, the air supply direction can be concentrated outward, so that the warm air is more concentrated to the working area, reducing air heat floating. In summer, the angle of the diffuser can be changed to ensure that the cold air is attached to a large extent. Then, the cold air passing through the diffuser first reaches the top of the room (ceiling air outlet situation) or around the wall (wall air outlet situation), so that the cold air is evenly distributed in the entire space, avoiding the cold air blowing directly to the working area, which is easy to cause air conditioning cold.
[0030] The wall panel 1 is internally connected with a U-shaped air vent frame 2 , the air vent is formed in the air vent frame 2 , and the end of the fixing frame 3 is fixed on the air vent frame 2 .
[0031] This makes it easier to install and fix the fixing bracket.
[0032] The two ends of the diffuser 4 are connected to the fixing frame through a rotating shaft and a bearing installed at the middle position of the end along the length direction of the diffuser 4.
[0033] This makes it easier to adjust the rotation of the diffuser.
[0034] The connecting rod 5 and the side surface of the middle part of the diffuser plate 4 can be rotatably connected.
[0035] In this way, the connecting rod can better drive the diffuser to rotate.
[0036] A groove is arranged on one side of the middle of the diffuser 4, and the connecting rod 5 is movably installed in the groove and rotatably connected through the rotating shafts on both sides and the side walls of the groove. Figure 2 .
[0037] In this way, the connecting rod can better drive the diffuser to rotate.
[0038] Wherein, the pressing mechanism (see Figure 3-5) includes a pressure-applying member 7, a pressure-bearing member 8 and a mounting tube 9, each of which is cylindrical and coaxially arranged. The mounting tube 9 is mounted in a mounting hole in the middle position of the fixing frame. The inner surface of the mounting tube 9 protrudes inward to form a circumferential limit strip 10 arranged along the axial direction; one end of the pressure-applying member 7 is an extrusion end located outside the mounting tube, and the other end is a pressure-applying end matched in the mounting tube 9. The outer surface of the pressure-applying member is provided with a circumferential limit groove 11 and a circumferential limit strip 10 for sliding cooperation to achieve circumferential limitation; one end of the pressure-bearing member 8 is an execution end located outside the mounting tube, and the other end is a pressure-bearing end matched in the mounting tube, and the execution end and the pressure-bearing end are rotatably arranged relative to each other; the pressure end of the pressure-applying member 7 and the pressure end of the pressure-bearing member 8 are each provided with a circle of triangular convex teeth, and the pressure-bearing member Evenly spaced deep tooth grooves 12 and shallow tooth grooves 13 are formed between the convex teeth at the pressure end, the width of the deep tooth grooves 12 and the shallow tooth grooves 13 is greater than or equal to the width of the circumferential limit strip 10, and the bottoms of the deep tooth grooves 12 and the shallow tooth grooves 13 and the end of the circumferential limit strip facing the pressure member are all inclined surfaces inclined in the same direction; a compression spring 14 is also sleeved on the outside of the pressure member, and the compression spring 14 acts between the pressure member and the mounting tube and applies pressure to the pressure member in the direction of the pressure-applying member; when the deep tooth groove 12 of the pressure end of the pressure member 8 abuts against the circumferential limit strip 10, the convex tooth surface that the extrusion end of the pressure-applying member 7 can fit with the pressure end of the pressure member is an inclined surface in the same direction as the bottom of the deep tooth groove, and after fitting, the tooth tips of the convex teeth at both ends are each separated from the tooth roots of the convex teeth at the other end by a distance.
[0039] In this way, the pressure-bearing member abuts against the circumferential limit strip in the installation tube under the action of the compression spring. By simply pressing the extrusion end of the pressure-applying member, the pressure-bearing member can be controlled to switch between the deep tooth groove and the circumferential limit strip abutment and the shallow tooth groove and the circumferential limit strip abutment, thereby realizing the switching of the pressure-bearing member between two different positions in the axial direction. Because when the deep tooth groove of the pressure-bearing end of the pressure-bearing member abuts against the circumferential limit strip, the convex tooth surface that the extrusion end of the pressure-applying member can fit with the pressure-bearing end of the pressure-bearing member is an inclined surface in the same direction as the bottom of the deep tooth groove, and after fitting, the tooth tips of the convex teeth at both ends are each at a distance from the tooth roots of the convex teeth at the other end, and are not meshed in place. Therefore, during the switching control, when the pressure-bearing member is pushed out of the circumferential limit strip limit by the extrusion of the convex teeth of the pressure-applying member, the extrusion end of the pressure-applying member can further mesh with the convex teeth of the pressure-bearing end of the pressure-bearing member, thereby pushing the pressure-bearing end of the pressure-bearing member to rotate circumferentially by a certain angle. In this way, after the force of the pressure member is canceled, the pressure-receiving end that has rotated a certain angle under the reset action of the compression spring can switch between the deep tooth groove and the shallow tooth groove to achieve abutment with the circumferential limit strip. Then, the switching control of the two states is achieved by the extrusion of the pressure member. It is very convenient and fast, and the structure is ingenious and feasible.
