Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air duct component and a mobile air conditioner. Background Art

[0002] Existing mobile air conditioners all need to install a protective mesh cover on the air outlet of the air duct. Pins are set on the opposite sides of the existing protective mesh cover. It is necessary to manually insert the pins on one side of the protective mesh cover into the mounting holes of the air duct, and then insert the pins on the other side of the protective mesh cover into the mounting holes of the air duct. The assembly efficiency is low, and the mounting holes and the pins are generally matched with clearance. When the whole machine vibrates greatly, the protective mesh cover is prone to resonate or shake and make abnormal noises. Summary of the invention

[0003] The problem solved by the invention is that in the existing mobile air conditioner, the protective net cover has low assembly efficiency and is prone to resonance or vibration to emit abnormal noise.

[0004] In order to solve the above problems, in a first aspect, the present invention provides an air duct assembly, the air duct assembly comprising:

[0005] The first shell is provided with an air outlet, a mounting hole is provided on one side of the air outlet, and a hanging slot is provided on the other side of the air outlet;

[0006] The protective mesh cover comprises a mesh cover body, pins and a suspension beam, wherein the pins are connected to one side of the mesh cover body and inserted into the mounting hole, and the suspension beam is connected to the other side of the mesh cover body and is inserted into the suspension groove;

[0007] The second shell is connected to the first shell. A pressing platform is arranged on the second shell, and the pressing platform presses the suspension beam into the suspension groove.

[0008] In this way, the pins on one side of the protective mesh are manually inserted into the mounting holes on the first shell body first, which can limit the movement of the protective mesh in the front, rear, left and right directions; the suspension beam on the other side of the protective mesh is then inserted into the suspension groove of the first shell body, and the pressing platform on the second shell body is used to press the suspension beam into the suspension groove, which can limit the movement of the protective mesh in the up and down directions. Overall, the protective mesh is fixed in all directions. During the operation of the whole machine, the protective mesh will not resonate or shake and make abnormal noises. Moreover, the entire assembly process is simple and convenient, which greatly improves the assembly efficiency.

[0009] In an optional embodiment, the opening of the hanging slot is oriented parallel to the protective mesh cover and away from the mounting hole.

[0010] In this way, the suspension beam of the protective net cover is suspended in the suspension groove, and the suspension groove supports the suspension beam, so that the height position of the protective net cover can be accurately controlled, so that the protective net cover has a certain downward deformation space.

[0011] In an optional embodiment, the suspension groove is a U-shaped groove, and the depth of the suspension groove is less than or equal to 1 / 2 of the diameter of the suspension beam.

[0012] In this way, the depth of the suspension groove can meet the requirement of accommodating the suspension beam without being too deep to cause demoulding difficulty.

[0013] In an optional embodiment, the pressing platform is a rib, the height of the rib protruding perpendicular to the surface of the second shell is less than 2 mm, and the thickness of the rib parallel to the surface of the second shell is less than 1 mm.

[0014] In this way, the pressing platform is designed as a rib, which is easy to shape. The rib height is less than 2mm and the thickness is less than 1mm. When the rib size is small, it can produce a certain deformation when it contacts the protective mesh cover, so that the protective mesh cover contacts all ribs and the force is evenly distributed.

[0015] In an optional embodiment, a fixing groove is further provided on the first shell, and at least one end of the suspension beam is inserted into the fixing groove.

[0016] In this way, at least one end of the suspension beam is inserted into the fixing groove, which can further increase the stability of the protective net cover.

[0017] In an optional embodiment, the opening of the fixing slot is oriented perpendicular to the protective mesh cover.

[0018] In this way, after the pin of the protective net cover is inserted into the mounting hole, the end of the suspension beam is snapped into the fixing groove, which can pre-position the protective net cover. Then the protective net cover is slid in the fixing groove, so that the suspension beam of the protective net cover can slide toward the suspension groove and be snapped into the suspension groove.

[0019] In an optional embodiment, the fixing groove is a trumpet-shaped groove, and the width of the narrowest part of the fixing groove is smaller than the diameter of the suspension beam.

[0020] In this way, when the end of the suspension beam is clamped into the fixing groove, the trumpet-shaped groove can automatically center and guide the end of the suspension beam, and the width of the narrowest part of the fixing groove is smaller than the diameter of the suspension beam, which can clamp the end of the suspension beam.

[0021] In an optional embodiment, fixing grooves are provided on opposite sides of the air outlet, and both ends of the suspension beam are inserted into the fixing grooves.

[0022] In an optional embodiment, the suspension beam is a U-shaped structure, both ends of the suspension beam are connected to the mesh cover body, and the middle of the suspension beam is inserted into the suspension groove.

[0023] In an alternative embodiment, the pins are formed by extending the material at both ends of the suspension beam.

[0024] In this way, the suspension beam and the pin can be formed in one piece, which is not only convenient to manufacture but also has a firm connection.

[0025] In an optional embodiment, the mesh cover body is a diamond-shaped mesh material, and the diamond-shaped mesh material is welded to both ends of the suspension beam.

[0026] In this way, the diamond mesh material is an integrated structure with stable structure, consistent mesh size, uniform air output and less wind noise.

[0027] In an optional embodiment, the width of the protective mesh cover is greater than the width of the air outlet, and the gap between the edge of the protective mesh cover and the edge of the air outlet is less than or equal to 5.5 mm.

[0028] In this way, the protective mesh cover can basically cover the air outlet and protect the parts inside the air duct. At the same time, the gap between the protective mesh cover and the air outlet is small, and the child's experimental finger just cannot pass through the gap of 5.5mm, which improves safety.

[0029] In a second aspect, the present invention provides a mobile air conditioner, comprising the air duct assembly of any one of the aforementioned embodiments.

[0030] In this way, the protective mesh cover is stably fixed on the air duct assembly. During the operation of the whole machine, the protective mesh cover will not resonate or shake and make abnormal noises. Moreover, the whole assembly process is simple and convenient, which greatly improves the assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The protective mesh cover installed on the air outlet of the existing mobile air conditioner is generally inconvenient to assemble and has low assembly efficiency. Moreover, the mounting holes and pins are generally clearance-matched. When the whole machine vibrates greatly, the protective mesh cover is prone to resonance or vibration and abnormal noise. The embodiment of the present invention provides an air duct assembly and a mobile air conditioner, which can improve the assembly efficiency of the protective mesh cover and can also ensure that the protective mesh cover is installed stably without abnormal noise.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] See also Figure 1 The present embodiment provides an air duct assembly 100, which includes a first housing 10, a second housing 20 and a protective mesh cover 30, wherein the first housing 10 and the second housing 20 are connected to form an air duct, an air outlet 11 of the air duct is opened on the first housing 10, and the protective mesh cover 30 is installed at the air outlet 11. Of course, in other embodiments, the protective mesh cover 30 can also be installed at the air inlet.

[0045] See also Figure 2 The protective mesh cover 30 includes a mesh cover body 31, a pin 32 and a suspension beam 33, wherein the pin 32 is connected to one side of the mesh cover body 31, and the suspension beam 33 is connected to the other side of the mesh cover body 31. The suspension beam 33 is a U-shaped structure, and the upper and lower widths L1 of the suspension beam 33 can be designed to be 10 mm, that is, the length L1 of the vertical sections at both ends of the suspension beam 33 can be designed to be 10 mm, and the two ends of the suspension beam 33 are connected to the mesh cover body 31, so that the structure of the suspension beam 33 is simple. The pin 32 is formed by extending the material at both ends of the suspension beam 33. In this way, the suspension beam 33 and the pin 32 can be integrally formed, which is not only convenient to manufacture, but also firmly connected. The mesh cover body 31 is a diamond mesh material, and the diamond mesh material is welded to both ends of the suspension beam 33. In this way, the diamond mesh material is an integrally formed structure with a stable structure, consistent mesh size, uniform air outlet, and less wind noise.

[0046] The protective mesh cover 30 is a symmetrical structure, and the front and back sides of the protective mesh cover 30 have the same structural form. During the assembly of the protective mesh cover 30, the front and back sides of the protective mesh cover 30 do not need to be distinguished, so as to simplify the assembly process.

[0047] The width L2 of the protective mesh cover 30 is greater than the width of the air outlet 11. Specifically, the width L2 of the protective mesh cover 30 can be designed to be greater than 10 mm, and the gap between the edge of the protective mesh cover 30 and the edge of the air outlet 11 is less than or equal to 5.5 mm. In this way, the protective mesh cover 30 can basically cover the air outlet 11 and protect the parts inside the air duct. At the same time, the gap between the protective mesh cover 30 and the air outlet 11 is small, and a child's experimental finger just cannot pass through the gap of 5.5 mm, which prevents the user's finger from accidentally extending into the air outlet 11 and causing injury, thereby improving safety.

[0048] In other embodiments, the protective mesh cover 30 can be designed as an integrally formed structure and formed in one go by a casting process. In this embodiment, only one suspension beam 33 is designed on the protective mesh cover 30, and this one suspension beam 33 spans the entire mesh cover body 31. In other embodiments, the length of each suspension beam 33 can be shortened, and multiple suspension beams 33 can be arranged at intervals on one side of the mesh cover body 31. Of course, only the two outermost suspension beams 33 can be aligned with the fixing grooves 14 on the first shell 10 (see Figure 5 )Cooperate.

[0049] In this embodiment, the size of the protective mesh cover 30 is only described as an example. In other embodiments, the size of the protective mesh cover 30 can be designed according to the size of the air outlet 11.

[0050] See also Figure 3 and Figure 4 A mounting hole 12 is provided on one side of the air outlet 11 on the first shell 10. There are two mounting holes 12. The spacing between the two mounting holes 12 is equal to the spacing between the two pins 32. The two pins 32 are respectively inserted into the two mounting holes 12 to limit the movement of the protective mesh cover 30 in the front, back, left and right directions.

[0051] The diameter of the mounting hole 12 is greater than or equal to 0.3 mm, and specifically, can be designed to be between 0.3 mm and 0.5 mm. The mounting hole 12 is designed as a through hole so that the length of the pin 32 can be designed more freely. Of course, the pin 32 is preferably not extended out of the mounting hole 12 to avoid scratching other parts or workers.

[0052] In this embodiment, the number of mounting holes 12 is equal to the number of pins 32, both of which are two. In other embodiments, if the size of the protective mesh cover 30 is larger, more mounting holes 12 and pins 32 can be designed, and the pins 32 are arranged at intervals on one side of the mesh cover body 31. After the pins 32 are matched with the mounting holes 12, the overall shape of the protective mesh cover 30 can be supported and stabilized to prevent the protective mesh cover 30 from being deformed.

[0053] See also Figure 3 and Figure 5 A hanging groove 13 is provided on the other side of the air outlet 11 on the first shell 10. The plurality of hanging grooves 13 are arranged at intervals, and the opening of the hanging groove 13 is parallel to the protective mesh cover 30 and away from the mounting hole 12. The middle part of the hanging beam 33 of the protective mesh cover 30 is inserted into the hanging groove 13 of the first shell 10. The hanging groove 13 supports the hanging beam 33, and can accurately control the height position of the protective mesh cover 30, so that the protective mesh cover 30 has a certain downward deformation space. The hanging groove 13 is a U-shaped groove, and the depth of the hanging groove 13 is less than or equal to 1 / 2 of the diameter of the hanging beam 33. In this way, the depth of the hanging groove 13 meets the requirement of accommodating the hanging beam 33, but is not too deep to cause difficulty in demolding.

[0054] In this embodiment, there are three suspension grooves 13, which are evenly spaced and arranged. The three suspension grooves 13 support the suspension beam 33 together, which can support the suspension beam 33 stably and evenly, and avoid deformation of the suspension beam 33 due to uneven force.

[0055] In other embodiments, the suspension groove 13 can also be designed as a trumpet-shaped groove, and the width of the narrowest part of the suspension groove 13 is smaller than the diameter of the suspension beam 33. In this way, in the process of the middle part of the suspension beam 33 being clamped into the suspension groove 13, the trumpet-shaped groove can automatically center and guide the middle part of the suspension beam 33, and the width of the narrowest part of the suspension groove 13 is smaller than the diameter of the suspension beam 33, so that the middle part of the suspension beam 33 can be clamped.

[0056] In order to further improve the stability of the protective mesh cover 30, a fixing groove 14 is further provided on the first shell 10. There are two fixing grooves 14, which are distributed on opposite sides of the air outlet 11. The two ends of the suspension beam 33 are respectively inserted into the two fixing grooves 14. The opening of the fixing groove 14 is perpendicular to the protective mesh cover 30. In this way, after the pin 32 of the protective mesh cover 30 is inserted into the mounting hole 12, the end of the suspension beam 33 is inserted into the fixing groove 14, which can play a role in pre-positioning the protective mesh cover 30. Then, the protective mesh cover 30 is made to slide in the fixing groove 14, so that the suspension beam 33 of the protective mesh cover 30 can slide toward the suspension groove 13 and be inserted into the suspension groove 13.

[0057] The fixing groove 14 is a trumpet-shaped groove, and the width of the narrowest part of the fixing groove 14 is smaller than the diameter of the suspension beam 33, and the diameter of the suspension beam 33 can be designed to be 0.3 mm. In this way, when the end of the suspension beam 33 is inserted into the fixing groove 14, the trumpet-shaped groove can automatically center and guide the end of the suspension beam 33, and the width of the narrowest part of the fixing groove 14 is smaller than the diameter of the suspension beam 33, so that the end of the suspension beam 33 can be clamped.

[0058] See also Figure 6 and Figure 7 The assembly process of the first housing 10 and the protective mesh cover 30 is as follows: First, insert the pin 32 on one side of the protective mesh cover 30 into the mounting hole 12 on the first housing 10, which can limit the movement of the protective mesh cover 30 in the front, back, left, and right directions. Then, insert the end of the suspension beam 33 into the fixing groove 14, which can play a role in pre-positioning the protective mesh cover 30 and further limit the movement of the protective mesh cover 30 in the left and right directions. Finally, slide the two ends of the suspension beam 33 in the fixing groove 14, slide the middle part of the suspension beam 33 toward the suspension groove 13, and insert it into the suspension groove 13, which can further limit the movement of the protective mesh cover 30 in the front and back directions.

[0059] Of course, during the assembly process of the first shell 10 and the protective mesh cover 30, the end of the suspension beam 33 can be first inserted into the fixing groove 14, and then the protective mesh cover 30 can be slid downward along the fixing groove 14 to insert the pin 32 of the protective mesh cover 30 into the mounting hole 12, and then the middle part of the suspension beam 33 of the protective mesh cover 30 can be inserted into the suspension groove 13.

[0060] See also Figure 1 During the process of assembling the second shell 20 into the first shell 10, the edge of the second shell 20 fits against the edge of the first shell 10, and the second shell 20 slides toward the first shell 10 along the length direction of the protective mesh cover 30, that is, the second shell 20 slides into the first shell 10 from the suspension beam 33 to the pin 32.

[0061] See also Figure 8 and Fig. 9 A pressing platform 21 is provided on the second shell 20. After the second shell 20 is assembled on the first shell 10, the pressing platform 21 presses the suspension beam 33 into the suspension groove 13. Specifically, the pressing platform 21 is a rib, and a plurality of ribs are arranged at intervals. The height of the ribs protruding perpendicular to the surface of the second shell 20 is less than 2 mm, and the thickness of the ribs parallel to the surface of the second shell 20 is less than 1 mm. In this way, the pressing platform 21 is designed as a rib, which is convenient to shape. The height of the ribs is less than 2 mm and the thickness is less than 1 mm. When the size of the ribs is small, a certain deformation can be generated when contacting the protective mesh cover 30, so that the protective mesh cover 30 contacts all the ribs and is evenly stressed.

[0062] In this embodiment, there are four pressing platforms 21, and the four pressing platforms 21 are evenly arranged. The four pressing platforms 21 press the suspension beam 33 together, so that the suspension beam 33 can be evenly stressed. Not only is the pressing force greater, which prevents the suspension beam 33 from moving, but it also does not cause deformation of the suspension beam 33.

[0063] In this embodiment, the pressing platform 21 is designed as a rib. In other embodiments, the pressing platform 21 can be designed as an elastic strip and the elastic strip is bonded to the second shell 20. The elastic strip extends along the length direction of the suspension beam 33. The length of the elastic strip can be less than or equal to the length of the suspension beam 33. The thickness of the elastic strip can be 1 mm. In this way, not only can the shape and structure of the second shell 20 be simplified and the production cost can be reduced, but also the pressure on the suspension beam 33 can be uniform and the friction force can be greater.

[0064] The assembly process of the air duct assembly 100 provided in this embodiment is as follows: first, assemble the protective mesh cover 30 onto the first shell 10, that is, first insert the pin 32 on one side of the protective mesh cover 30 into the mounting hole 12 on the first shell 10, then insert the end of the suspension beam 33 into the fixing groove 14, and then slide the two ends of the suspension beam 33 in the fixing groove 14, so that the middle part of the suspension beam 33 slides toward the suspension groove 13 and is inserted into the suspension groove 13. Secondly, assemble the second shell 20 onto the first shell 10, the first shell 10 and the second shell 20 are mutually clamped or screwed, and the pressing platform 21 on the second shell 20 presses the suspension beam 33 into the suspension groove 13, which can limit the movement of the protective mesh cover 30 in the up and down directions, and realizes the overall all-round fixation of the protective mesh cover 30. During the operation of the whole machine, the protective mesh cover 30 will not resonate or shake and make abnormal noises. Moreover, the whole assembly process is simple and convenient, which greatly improves the assembly efficiency.

[0065] This embodiment also provides a mobile air conditioner, which includes the aforementioned air duct assembly 100. In this way, the protective mesh cover 30 is stably fixed on the air duct assembly 100, and during the operation of the whole machine, the protective mesh cover 30 will not resonate or shake to make abnormal noises, and the whole assembly process is simple and convenient, which greatly improves the assembly efficiency.

[0067] 1. The assembly process of the protective mesh cover 30 is simple and the assembly efficiency is high. Specifically, first insert the pin 32 on one side of the protective mesh cover 30 into the mounting hole 12 on the first shell 10, then insert the end of the suspension beam 33 into the fixing groove 14, and make the two ends of the suspension beam 33 slide in the fixing groove 14 until the middle of the suspension beam 33 slides toward the suspension groove 13 and is inserted into the suspension groove 13. Finally, assemble the second shell 20 onto the first shell 10 to complete the installation of the protective mesh cover 30;

[0068] 2. The protective mesh cover 30 is installed stably and will not make abnormal noises due to the resonance or vibration of the whole machine.
