Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner outdoor units, in particular to an air conditioner outdoor unit with self-cleaning fan blades. Background Art

[0002] The outdoor unit of the air conditioner is the key component responsible for heat dissipation in the air conditioning system. It is usually installed outdoors. Its main function is to discharge indoor heat to the external environment. Through its built-in compressor and heat exchanger, the refrigerant circulates between gas and liquid, thereby taking away the indoor heat. In addition, the outdoor unit also contains a fan to enhance the heat dissipation effect. In terms of design, the outdoor unit usually has rainproof and rust-proof properties to adapt to the changeable outdoor weather conditions. Although the structure of the outdoor unit is relatively complex, modern technology is committed to simplifying the installation process, improving energy efficiency and reducing noise, ensuring that continuous and stable cooling or heating is provided to the indoor room.

[0003] In actual applications, existing air-conditioning outdoor units are usually difficult to quickly fix on the exterior walls of buildings, so installers have to perform complex installation operations at high altitudes. Existing devices are usually complicated to install, requiring operators to hang them on the exterior walls of buildings for installation. This not only poses a potential threat to the life safety of operators, but also may require the use of cranes or other high-altitude work equipment during the installation process, increasing the difficulty and risk of construction. In view of this, we provide an air-conditioning outdoor unit with self-cleaning fan blades. Utility Model Content

[0006] In the above, the adjustment rod is located on one side of the bottom surface of the outer frame, and one end of the outer wall of the adjustment rod is rotatably connected to the center of the bottom surface of the outer frame through the adjustment frame, and a brush is fixedly connected to one side of the corresponding surface of the outer wall of the adjustment rod.

[0007] As mentioned above, one side of the corresponding surface of the outer wall of the adjusting rod is fixedly connected with a connecting shaft, and one end of the outer wall of the connecting shaft is fixedly connected with a meshing tooth.

[0008] As mentioned above, a control motor is fixedly connected to the center of the bottom surface of the outer frame, and a driving tooth is fixedly connected to the output end of the control motor. One side of the outer wall of the driving tooth and the outer wall of the one side of the meshing tooth are meshed with each other and rotatably connected. The brush is rotatably connected to the output end of the control motor through the driving tooth of the meshing tooth.

[0009] As mentioned above, the outer wall of the outer frame is provided with a plurality of corresponding fixing grooves on the side away from the dustproof and heat dissipation net, and the outer frame is fixedly connected to the mounting frame through the fixing grooves, the inner center of the fixing groove is slidably connected to a limit block, and a set of corresponding slide rails is provided on one side of the limit block.

[0010] As mentioned above, the outer wall of one side of the slide rail is fixedly connected to the inner wall of the fixed groove, and one end of the outer wall of the slide rail is connected through the outer wall of the limit block, the inner side of the limit block is slidably connected to one end of the outer wall of the slide rail, and a plurality of limit springs are fixedly connected to the inner side of the limit block, and the outer wall of the limit spring is fixedly connected to the inner wall of the fixed groove at one end away from the limit block.

[0011] As mentioned above, a plurality of sliders are slidably connected to the outer wall of the outer frame away from the dustproof and heat dissipation net, and one side of the outer wall of the slider penetrates the outer wall of one side of the outer frame and is fixedly connected to one side of the outer wall of the limit block.

[0012] Compared with the prior art, the air conditioner outdoor unit with self-cleaning fan blades has the following beneficial effects:

[0013] 1. When the dust on the surface of the heat dissipation blade needs to be cleaned, the driving teeth and the meshing teeth are meshed with each other, and the meshing teeth are fixed to one end of the outer wall of the connecting shaft. Since the connecting shaft fixes the two adjusting rods at the bottom end of the inner part of the outer frame, the device can make the driving teeth fixed at the output end drive the connecting shaft and the adjusting rod to rotate the brush to a vertical state only by driving the control motor. After the brush is perpendicular to the bottom end of the inner wall of the outer frame, the brush fits with the outer wall of the heat dissipation blade, and the heat dissipation blade in the working state can be cleaned. Therefore, when the device is working, the driving teeth and the meshing teeth cooperate with each other, and the brush is rotated to a vertical state with the bottom end of the inner wall of the outer frame, so that the heat dissipation blade can be self-cleaned.

[0014] Second, when the utility model is installed on the external rack, it is only necessary to fix the mounting bracket on the external facade of the building, tilt the fixing groove slightly downward, align the top of the inner wall of the fixing groove with the top of one side of the mounting bracket, insert the top of one side of the mounting bracket into the top of the inner wall of the fixing groove, and after the top of the inner wall of the fixing groove is abutted, the external rack is used as a fulcrum, and the fixing groove is slowly rotated to a vertical state, and one side of the outer wall of the mounting bracket is completely fitted with one side of the inner wall of the fixing groove. When the fixing groove is rotated to a vertical state, one side of the bottom of the mounting bracket abuts against the outer wall inclined surface of the limit block, and the mounting bracket pushes the limit block along the outer wall of the slide rail to the other end of the slide rail, so that the limit block When the positioning block slides, it compresses the limit spring at the same time. When one side of the outer wall of the mounting frame is completely fitted with the inner wall of the fixing groove, the limit block loses the thrust from the outer wall of one side of the mounting frame, and the limit block is pushed by the limit spring along the outer wall of the slide rail to the outer wall of the mounting frame on the side away from the fixing groove, and contacts with one side of the outer wall of the mounting frame, so that the outer frame can be fixed to the outer wall of one side of the mounting frame. The device realizes rapid installation of the external frame by cooperating with the mounting frame and the limit block, thereby effectively shortening the working time of the operator on the facade of the building and further reducing the potential danger of the operator during installation operations.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the utility model provides a technical solution: an air-conditioning outdoor unit with self-cleaning fan blades, comprising an outer frame 1 and a heat dissipation roller 103, a dustproof heat dissipation net 101 is fixedly connected to one side of the inner wall of the outer frame 1, and a heat dissipation frame 102 is fixedly connected to one side of the inner wall of the outer frame 1, the heat dissipation roller 103 is rotatably connected to the inner center of the outer frame 1 through the heat dissipation frame 102, a plurality of heat dissipation blades 104 are fixedly connected to one end of the outer wall of the heat dissipation roller 103, and the heat dissipation blades 104 are rotatably connected to the inner center of the outer frame 1 through the heat dissipation roller 103, a plurality of adjustment frames 105 are fixedly connected to the inner bottom end of the outer frame 1, and the adjustment frames 105 are located at the center of the bottom surface of the outer frame 1, and a plurality of adjustment rods 106 are rotatably connected to the outer wall of the corresponding side of the adjustment frame 105.

[0024] When it is necessary to clean the dust on the surface of the heat dissipation blade 104, the driving teeth 1011 are meshed with the meshing teeth 109, and the meshing teeth 109 are fixed to one end of the outer wall of the connecting shaft 108. Since the connecting shaft 108 is fixedly connected to the two adjusting rods 106 at the bottom end of the outer frame 1, the device can drive the driving teeth 1011 fixed at the output end to drive the connecting shaft 108 and the adjusting rod 106 to rotate the brush 107 to a vertical state by only driving the control motor 1010. After the bottom end is vertical, the brush 107 fits with the outer wall of the heat dissipation blade 104, so that the heat dissipation blade 104 in the working state can be cleaned. When installing the external frame 1, it is only necessary to fix the mounting frame 201 on the facade of the building, and then tilt the fixing groove 2 slightly downward, align the top of the inner wall of the fixing groove 2 with the top of one side of the mounting frame 201, so that the top of one side of the mounting frame 201 is inserted into the top of the inner wall of the fixing groove 2, and after the top of the fixing groove 2 is abutted, the external frame 1 is used with the top of one side of the mounting frame 201 as a fulcrum, and the fixing groove 2 is slowly rotated to the vertical position. The mounting bracket 201 is in a straight state, and one side of the outer wall of the mounting bracket 201 is completely fitted with one side of the inner wall of the fixing groove 2. When the fixing groove 2 is rotated to a vertical state, one side of the bottom of the mounting bracket 201 contacts the outer wall slope of the limit block 202. The mounting bracket 201 pushes the limit block 202 along the outer wall of the slide rail 203 to the other end of the slide rail 203, so that when the limit block 202 slides, it compresses the limit spring 204 at the same time. When one side of the outer wall of the mounting bracket 201 is completely fitted with the inner wall of the fixing groove 2, the limit block 202 loses the outer wall of the mounting bracket 201. The limiting block 202 is pushed by the limiting spring 204 along the outer wall of the slide rail 203 to the outer wall of the mounting frame 201 away from the fixing groove 2, and contacts with one side of the outer wall of the mounting frame 201, so that the outer frame 1 can be fixed to the outer wall of one side of the mounting frame 201. Thus, the device realizes the rapid installation of the outer frame 1 by making the mounting frame 201 and the limiting block 202 cooperate with each other, thereby effectively shortening the working time of the operators on the facade of the building and further reducing the potential danger of the operators during the installation operation.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the adjusting rod 106 is located on one side of the bottom surface of the outer frame 1, and one end of the outer wall of the adjusting rod 106 is rotatably connected to the center of the bottom surface of the outer frame 1 through the adjusting frame 105, a brush 107 is fixedly connected to one side of the corresponding surface of the outer wall of the adjusting rod 106, and a connecting shaft 108 is fixedly connected to one side of the corresponding surface of the outer wall of the adjusting rod 106, and one end of the outer wall of the connecting shaft 108 is fixedly connected to a meshing tooth 109, a control motor 1010 is fixedly connected to the center of the bottom surface of the outer frame 1, and a driving tooth 1011 is fixedly connected to the output end of the control motor 1010, one side of the outer wall of the driving tooth 1011 and the outer wall of one side of the meshing tooth 109 are meshed and rotatably connected to each other, and the brush 107 is rotatably connected to the output end of the control motor 1010 through the driving tooth 1011 through the meshing tooth 109.

[0026] When it is necessary to clean the dust on the surface of the heat dissipation blade 104, the driving teeth 1011 are meshed with the meshing teeth 109, and the meshing teeth 109 are fixed to one end of the outer wall of the connecting shaft 108. Since the connecting shaft 108 fixes the two adjusting rods 106 at the bottom end of the inner part of the outer frame 1, the device only needs to drive the control motor 1010 to make the driving teeth 1011 fixed at the output end drive the connecting shaft 108 and the adjusting rod 106 to rotate the brush 107 to a vertical state. After the brush 107 is perpendicular to the bottom end of the inner wall of the outer frame 1, the brush 107 fits against the outer wall of the heat dissipation blade 104, and the heat dissipation blade 104 in the working state can be cleaned. Therefore, when the device is working, the driving teeth 1011 and the meshing teeth 109 cooperate with each other, and the brush 107 is rotated to a vertical state with the bottom end of the inner wall of the outer frame 1, so that the heat dissipation blade 104 can be self-cleaned.

[0027] like Figure 2 and Figure 5 As shown, a plurality of corresponding fixing grooves 2 are provided on the side of the outer wall of the outer frame 1 away from the dustproof heat dissipation net 101, and the outer frame 1 is fixedly connected to the mounting frame 201 through the fixing groove 2, the inner center of the fixing groove 2 is slidably connected to the limit block 202, and a group of corresponding slide rails 203 are provided on the inner side of the limit block 202, the outer wall of one side of the slide rail 203 is fixedly connected to the inner wall of the fixing groove 2, and one end of the outer wall of the slide rail 203 is connected through and through the outer wall of the limit block 202, the inner side of the limit block 202 is slidably connected to one end of the outer wall of the slide rail 203, and a plurality of limiting springs 204 are fixedly connected to the inner side of the limit block 202, the outer wall of the limiting spring 204 is fixedly connected to one end of the inner wall of the fixing groove 2 away from the limit block 202, and the outer wall of the outer frame 1 is slidably connected to one side of the inner wall of the fixing groove 2, and a plurality of sliders 205 are slidably connected to the side, and one side of the outer wall of the slider 205 passes through the outer wall of one side of the outer frame 1 and is fixedly connected to one side of the outer wall of the limit block 202.

[0028] When installing the external rack 1, it is only necessary to fix the mounting bracket 201 on the facade of the building, tilt the fixing slot 2 slightly downward, align the top of the inner wall of the fixing slot 2 with the top of one side of the mounting bracket 201, insert the top of one side of the mounting bracket 201 into the top of the inner wall of the fixing slot 2, and after they collide, use the top of one side of the mounting bracket 201 as a fulcrum, slowly rotate the fixing slot 2 to a vertical state, and make one side of the outer wall of the mounting bracket 201 completely fit with one side of the inner wall of the fixing slot 2. When the fixing slot 2 is rotated to a vertical state, one side of the bottom of the mounting bracket 201 contacts the outer wall inclined surface of the limit block 202, and the mounting bracket 201 pushes the limit block 202 along the outer wall of the slide rail 203 to the other end of the slide rail 203, so that the limit block 202 When sliding, it compresses the limit spring 204 at the same time. When one side of the outer wall of the mounting frame 201 is completely fitted with the inner wall of the fixing groove 2, since the limit block 202 loses the thrust from the outer wall of one side of the mounting frame 201, the limit block 202 is pushed by the limit spring 204 along the outer wall of the slide rail 203 to the outer wall of the mounting frame 201 on the side away from the fixing groove 2, and contacts with one side of the outer wall of the mounting frame 201, so that the outer frame 1 can be fixed to the outer wall of one side of the mounting frame 201. Therefore, the device realizes the rapid installation of the external frame 1 by making the mounting frame 201 and the limit block 202 cooperate with each other, thereby effectively shortening the working time of the operator on the facade of the building and further reducing the potential danger of the operator during the installation operation.

[0029] Working principle: When it is necessary to clean the dust on the surface of the heat dissipation blade 104, the driving teeth 1011 mesh with the meshing teeth 109, and the meshing teeth 109 are fixed to one end of the outer wall of the connecting shaft 108. Since the connecting shaft 108 fixes the two adjustment rods 106 at the bottom end of the outer frame 1, the device can drive the driving teeth 1011 fixed at the output end to drive the connecting shaft 108 and the adjustment rod 106 to rotate the brush 107 to a vertical position only by driving the control motor 1010. When the brush 107 is perpendicular to the bottom end of the inner wall of the outer frame 1, the brush 107 fits the outer wall of the heat dissipation blade 104, and the heat dissipation blade 104 in the working state can be cleaned. When installing the external frame 1, it is only necessary to fix the mounting frame 201 on the facade of the building, and then tilt the fixing groove 2 slightly downward, and align the top of the inner wall of the fixing groove 2 with the top of one side of the mounting frame 201, so that the top of one side of the mounting frame 201 is inserted into the top of the inner wall of the fixing groove 2, and after the top of the fixing groove 2 is pressed against the top, the external frame 1 is installed. 1Use the top of one side of the mounting frame 201 as a fulcrum, slowly rotate the fixing slot 2 to a vertical state, and make the outer wall of the mounting frame 201 completely fit with the inner wall of the fixing slot 2. When the fixing slot 2 is rotated to a vertical state, the bottom side of the mounting frame 201 contacts the outer wall slope of the limit block 202. The mounting frame 201 pushes the limit block 202 along the outer wall of the slide rail 203 to the other end of the slide rail 203, so that the limit block 202 slides and compresses the limit spring 204 at the same time. When the outer wall of the mounting frame 201 When one side of the wall is completely in contact with the inner wall of the fixing groove 2, since the limiting block 202 loses the thrust from the outer wall of the mounting frame 201, the limiting block 202 is pushed by the limiting spring 204 along the outer wall of the slide rail 203 to the outer wall of the mounting frame 201 away from the fixing groove 2, and contacts with one side of the outer wall of the mounting frame 201, the outer frame 1 can be fixed to the outer wall of the mounting frame 201, so that the device can achieve rapid installation of the external frame 1 by making the mounting frame 201 and the limiting block 202 cooperate with each other.
