Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a connection structure and a household appliance. Background Technology

[0002] In related technologies, a connecting structure is required between the air pressure switch pipe and the fan wheel in an air conditioner, allowing the airflow generated by the fan wheel to enter the air pressure switch for detection through the pipe. However, the connection between the connecting structure and the fan wheel requires screws for fixation, and the connection between the connecting structure and the pipe also requires fixing structures such as retaining rings for fixation. This results in complex installation of the connecting structure, pipe, and fan wheel, and makes maintenance and disassembly difficult. Utility Model Content

[0003] This application provides a connection structure and a household appliance to solve or improve the technical problems of complex installation and difficult maintenance and disassembly when connecting structural components and pipes.

[0004] An embodiment of this application provides a connection structure for a household appliance, the household appliance including a structural component and a pipe, the structural component having a mounting hole, and the connection structure including a first connection portion and a second connection portion. One end of the first connection portion is used to connect to the pipe; one end of the second connection portion is connected to the other end of the first connection portion, the second connection portion including a clearance groove and an elastic locking member, the elastic locking member being connected to the inner wall of the clearance groove and protruding from the clearance groove; the elastic locking member is adapted to retract into the clearance groove during the process of assembling the second connection portion into the mounting hole, so that after passing through the mounting hole, the elastic locking member can extend out of the clearance groove to engage with the structural component.

[0005] Thus, by setting an elastic locking element on the second connection part of the connecting structure, the elastic locking element can retract into the clearance groove during the assembly of the mounting hole, so that after the elastic locking element passes through the mounting hole, it can extend out of the clearance groove to engage with the structural component. No additional fixing structure is needed to fix the connecting structure and the structural component, which reduces the installation complexity and maintenance and disassembly difficulty between the connecting structure, pipe and structural component to a certain extent.

[0006] In some embodiments, the first connecting portion includes a first body and a fixing portion, the fixing portion being connected to the second connecting portion via the first body, and the fixing portion being configured to have an interference fit with the pipe.

[0007] In this way, by interfering with the fixing part of the pipe and the first connection part, the tightness between the connection structure and the pipe can be improved, the pipe can be prevented from falling off, and the sealing performance between the connection structure and the pipe can be improved to avoid air leakage at the connection.

[0008] In some embodiments, the fixing part has a gradually widening shape along the direction close to the second connecting part, and the diameter of the first body is smaller than the maximum diameter of the fixing part.

[0009] Thus, by setting the fixing part in a gradually expanding shape along the direction close to the second connecting part, a stepped shape can be formed at the connection between the first body and the fixing part, so that when the pipe is inserted into the first connecting part, it can be fixed by the stepped structure and prevent the pipe from falling off.

[0010] In some embodiments, the second connecting portion includes a second body, the interior of which is provided with a second air passage, the clearance groove is disposed on the second body and communicates with the second air passage, one end of the elastic locking member is connected to the second body, and the other end of the elastic locking member is suspended.

[0011] Thus, by suspending one end of the elastic locking member in the clearance groove, and with the clearance groove connected to the second air passage, space is provided for the elastic locking member to make way, facilitating the connection between the impeller and the second connecting part.

[0012] In some embodiments, the second body includes a sealing portion whose shape is adapted to the shape of the mounting hole, the sealing portion being configured to be embedded in the mounting hole to seal the mounting hole.

[0013] In this way, by embedding the sealing part into the mounting hole, the connection between the impeller and the second connecting part can be sealed to prevent air leakage.

[0014] In some embodiments, the sealing portion includes a profiled shaft, the mounting hole includes a profiled bore, and the profiled shaft is configured to be fitted into the profiled bore to seal the mounting hole and prevent the connecting structure from rotating.

[0015] Thus, by setting the mounting hole as an irregular hole and the sealing part as an irregular shaft, after connecting the mounting hole and the sealing part, the connection structure can be prevented from rotating with the impeller, thus preventing the connection structure from rotating and falling off.

[0016] In some embodiments, the second connecting portion includes a baffle, the first connecting portion is connected to the baffle, and the baffle is configured to clamp the structural member with the resilient locking member.

[0017] In this way, by clamping the wind turbine between the baffle and the elastic locking member, the tightness between the wind turbine and the first connection part can be improved, and the connection structure can be prevented from falling off.

[0018] In some embodiments, the baffle is provided with a through hole, the first connecting part is provided with a first air passage, the second connecting part is provided with a second air passage, and the first air passage and the second air passage are connected through the through hole.

[0019] Thus, by setting through holes in the baffle, the airflow generated by the wind turbine can enter the first air passage from the second air passage through the through holes, allowing the wind pressure switch to collect the air pressure of the wind turbine.

[0020] In some embodiments, the resilient locking member includes a first abutting surface and a second abutting surface. The second abutting surface is connected to the side wall of the clearance groove through the first abutting surface. The first abutting surface is inclined outward along the axis away from the connecting structure. The second abutting surface is perpendicular to the axis of the connecting structure. The connection between the first abutting surface and the second abutting surface has a rounded corner structure.

[0021] Thus, by setting the connection between the first and second abutment surfaces of the elastic locking member as a rounded corner structure, stress concentration can be reduced, the overall strength and stability of the elastic locking member can be improved, and when the mounting hole is inserted, it can smoothly contact the inner wall of the mounting hole, avoiding damage to the elastic locking member.

[0022] In some embodiments, the resilient locking elements include a plurality of resilient locking elements, which are symmetrically arranged about the axis of the connecting structure.

[0023] In this way, by symmetrically arranging multiple elastic locking elements about the axis of the connecting structure, the ability of the connecting structure to lock the impeller can be improved, thus preventing the connecting structure from falling off.

[0039] Please see Figure 1 , Figure 2 and Figure 3According to an embodiment of this application, a connection structure 300 is used for a household appliance 1000. The household appliance 1000 includes a structural component 100 and a wind pressure switch 200. The wind pressure switch 200 includes a pipe 210. The structural component 100 includes a mounting hole 110. The connection structure 300 includes a first connection portion 310 and a second connection portion 320. One end of the first connection portion 310 is used to connect to the pipe 210. One end of the second connection portion 320 is connected to the other end of the first connection portion 310. The second connection portion 320 includes a relief groove 321 and an elastic locking member 322. The elastic locking member 322 is connected to the inner wall of the relief groove 321 and protrudes from the relief groove 321. The elastic locking member 322 is adapted to retract into the relief groove 321 during the process of assembling the second connection portion 320 into the mounting hole 110, so that after the elastic locking member 322 passes through the mounting hole 110, it can extend out of the relief groove 321 to engage with the structural component 100.

[0040] Thus, by providing an elastic locking member 322 on the second connecting part 320 of the connecting structure 300, the elastic locking member 322 can retract into the relief groove 321 during the assembly of the mounting hole 110, so that after the elastic locking member 322 passes through the mounting hole 110, it can extend out of the relief groove 321 to engage with the structural member 100. No additional fixing structure is needed to fix the connecting structure 300 to the structural member 100, which reduces the installation complexity and maintenance and disassembly difficulty between the connecting structure 300, the pipe 210 and the structural member 100 to a certain extent.

[0041] Among them, household appliances 1000 include, but are not limited to, air conditioners; this application uses air conditioners as an example for illustration. An air conditioner is a device used to directly provide treated air to an enclosed room, space, or area. Air conditioners can provide cooling, heating, dehumidification, and air purification functions to the indoor environment. Air conditioners complete the cooling and heating processes through changes in the phase state, temperature, and pressure of the refrigerant within the outdoor unit.

[0042] Household appliance 1000 includes structural component 100 and pipe 210. Structural component 100 includes, but is not limited to, a fan wheel. This application uses a fan wheel as an example for illustration. Household appliance 1000 includes a wind pressure switch 200, and pipe 210 can connect the wind pressure switch 200 and the connecting structure 300.

[0043] Specifically, the household appliance 1000 includes a structural component 100 and a pressure switch 200. The structural component 100 can be a fan. The fan, by rotating, creates a low-pressure area, thereby driving airflow towards the household appliance 1000 for processing. The processed air is then cooled or heated. The structural component 100 then rotates again, releasing this processed air out of the air conditioner, thus producing a cooling or heating effect. For example, during cooling, the structural component 100 draws hot air into the air conditioner by rotating. The hot air exchanges heat with the evaporating and condensing refrigerant before flowing into the room, rapidly lowering the indoor temperature.

[0044] The wind pressure switch 200 can detect the wind pressure in the household appliance 1000 in real time and automatically adjust or control the operating status of the household appliance 1000 according to changes in wind pressure. For example, when the wind pressure is too high, the wind pressure switch 200 may disconnect the circuit and stop the operation of the household appliance 1000 to prevent damage to the equipment due to excessive wind pressure; when the wind pressure returns to normal, the wind pressure switch 200 will reconnect the circuit, allowing the household appliance 1000 to continue operating.

[0045] The wind pressure switch 200 includes a pipe 210, which can be an air guide pipe used to guide airflow to the wind pressure switch 200. The wind pressure switch 200 needs to detect the wind pressure generated by the detection structure 100, and the structure 100 has a mounting hole 110. The pipe 210 can be connected to the mounting hole 110 of the structure 100 through a connecting structure 300, allowing the airflow generated by the structure 100 to enter the wind pressure switch 200 for detection.

[0046] The connection structure 300 includes a first connection portion 310 and a second connection portion 320. The first connection portion 310 can be used to connect with the pipe 210, and the second connection portion 320 can be used to connect with the mounting hole 110 of the structural member 100. The first connection portion 310 and the second connection portion 320 are fixedly connected, so that the pipe 210 can be connected to the structural member 100 through the first connection portion 310 and the second connection portion 320.

[0047] The second connecting portion 320 includes a clearance groove 321 and an elastic locking member 322. The elastic locking member 322 can be made of a resilient material, such as rubber or plastic. The size of the clearance groove 321 is adapted to the size of the elastic locking member 322, allowing the elastic locking member 322 to be positioned within the clearance groove 321. One end of the elastic locking member 322 can connect to the inner wall of the clearance groove 321, allowing a portion of the elastic locking member 322 to protrude from the clearance groove 321.

[0048] During the process of assembling the second connecting part 320 into the mounting hole 110, the protruding part of the elastic locking member 322 will be subjected to the force exerted by the inner wall of the moving mounting hole 110, which will compress the elastic locking member 322 and move into the clearance groove 321, so that the elastic locking member 322 can avoid the mounting hole 110 and avoid hindering the connection between the mounting hole 110 and the second connecting part 320.

[0049] During the process of assembling the second connecting part 320 into the mounting hole 110, after the mounting hole 110 passes through the elastic locking member 322, the elastic locking member 322 will rebound without being squeezed, so that the elastic locking member 322 can move into the groove of the relief groove 321 and extend out of the relief groove 321. The part of the elastic locking member 322 that extends out of the relief groove 321 can engage with the structural member 100, thereby fixing the structural member 100 and the second connecting part 320.

[0050] Please see Figure 3 In some embodiments, the first connecting part 310 includes a first body 311 and a fixing part 312. The fixing part 312 is connected to the second connecting part 320 through the first body 311, and the fixing part 312 is configured to have an interference fit with the pipe 210.

[0051] Thus, by interfering with the fixing part 312 of the first connecting part 310, the tightness between the connecting structure 300 and the pipe 210 can be improved, preventing the pipe 210 from falling off, and the sealing performance between the connecting structure 300 and the pipe 210 can be improved, avoiding air leakage at the connection.

[0052] Specifically, the first connecting portion 310 includes a first body 311 and a fixing portion 312. The cooperation of the first body 311 and the fixing portion 312 secures the pipe 210 to the first connecting portion 310. Both the first body 311 and the fixing portion 312 are hollow cylinders, and their diameters are different. For example, in some embodiments, the fixing portion 312 has a gradually expanding shape towards the second connecting portion 320; that is, the diameter of the fixing portion 312 increases as it approaches the second connecting portion 320, and the diameter of the first body 311 is smaller than the maximum diameter of the fixing portion 312. This creates a stepped shape between the first body 311 and the fixing portion 312. When the fixing portion 312 is inserted into the pipe 210, the stepped structure can engage the pipe 210, preventing it from falling out.

[0053] The first body 311 and the fixing part 312 can be fixedly connected by integral molding or welding. For example, when the first body 311 and the fixing part 312 are fixedly connected by integral molding, the first body 311 and the fixing part 312 can be sleeved together by processes such as stamping, extrusion or molding, so that the first body 311 and the fixing part 312 are fixedly connected.

[0054] For example, if the first body 311 and the fixing part 312 are fixedly connected by welding, the first body 311 and the fixing part 312 can be fixedly connected by welding one end of the first body 311 to one end of the fixing part 312.

[0055] The fixing part 312 can be connected to the second connecting part 320 through the first body 311, thereby connecting the first connecting part 310 and the second connecting part 320. When the pipe 210 is inserted into the first connecting part 310, the fixing part 312 can be interference-fitted with the pipe 210 to fix the pipe 210. For example, the pipe 210 is elastic. During the insertion of the fixing part 312 into the pipe 210, the pipe 210 undergoes elastic deformation and is compressed against the fixing part 312. When the pipe 210 returns to its original shape, it will generate a clamping force on the fixing part 312. The clamping force can enable the pipe 210 and the fixing part 312 to transmit a large torque and load, thereby achieving a tight connection between the pipe 210 and the fixing part 312.

[0056] Furthermore, when the pipe 210 extends into the first body 311, the force generated when the pipe 210 returns to its original position can act on the stepped structure at the connection between the fixing part 312 and the first body 311, thereby the stepped structure can hinder the return of the pipe 210 and prevent the pipe 210 from falling off the fixing part 312.

[0057] Please see 3 and Figure 4 In some embodiments, the second connecting part 320 includes a second body 323, the interior of the second body 323 is provided with a second air passage 324, the clearance groove 321 is disposed on the second body 323 and communicates with the second air passage 324, one end of the elastic locking member 322 is connected to the second body 323, and the other end of the elastic locking member 322 is suspended.

[0058] Thus, by suspending one end of the elastic locking member 322 in the clearance groove 321, and with the clearance groove 321 connected to the second air passage 324, space can be provided for the elastic locking member 322 to make way, which facilitates the connection between the structural member 100 and the second connecting part 320.

[0059] Specifically, the second connecting part 320 includes a second body 323, which can be used to fix the structural member 100. The second body 323 can be a hollow cylinder, so that a second air passage 324 is provided inside the second body 323, which allows the airflow generated by the structural member 100 to pass through.

[0060] The clearance groove 321 is provided on the side wall of the second body 323, and the clearance groove 321 can penetrate through the side wall of the second body 323 and communicate with the second air passage 324. So when one end of the elastic locking member 322 is connected to the second body 323 (i.e. the inner wall of the clearance groove 321), the other end of the elastic locking member 322 can be suspended in the clearance groove 321. So when the elastic locking member 322 is squeezed by the mounting hole 110, the other end of the elastic locking member 322 can move into the clearance groove 321 and the second air passage 324. Thus, the clearance groove 321 and the second air passage 324 can serve as the moving space for the elastic locking member 322.

[0061] Please see Figure 2 and Figure 5 In some embodiments, the second body 323 includes a sealing portion 325, the shape of which is adapted to the shape of the mounting hole 110, and the sealing portion 325 is configured to be embedded in the mounting hole 110 to seal the mounting hole 110.

[0062] Thus, by embedding the sealing part 325 into the mounting hole 110, the connection between the structural member 100 and the second connecting part 320 can be sealed to prevent air leakage.

[0063] Specifically, the second body 323 includes a sealing portion 325, which seals the mounting hole 110 to prevent airflow in the second air passage 324 from leaking at the connection between the structural member 100 and the second connecting portion 320, thus affecting the detection results of the wind pressure switch 200. The sealing portion 325 protrudes from the second body 323, and its shape and size must be adapted to the shape of the mounting hole 110. For example, if the mounting hole 110 is circular, the sealing portion 325 is circular; if the mounting hole 110 is square, the sealing portion 325 is square. Furthermore, the diameter of the mounting hole 110 is larger than the diameter of the sealing portion 325, and the length of the mounting hole 110 is the same as the length of the sealing portion 325, so that the sealing portion 325 can be embedded in the mounting hole 110 to seal it.

[0064] It should be noted that if Figure 2 and Figure 5As shown, in some embodiments, the sealing part 325 includes a profiled shaft 3251, which protrudes from the side wall of the second body 323 and can be used to fix the mounting hole 110. The mounting hole 110 includes a profiled hole 111, the shape and size of which need to be adapted to the size and shape of the profiled shaft 3251. For example, if the profiled hole 111 is hexagonal, the profiled shaft 3251 is hexagonal; if the profiled hole 111 is square, the profiled shaft 3251 is square. Furthermore, the diameter of the profiled hole 111 is larger than the diameter of the profiled shaft 3251, and the length of the profiled hole 111 is the same as the length of the profiled shaft 3251, so that the profiled shaft 3251 can be fitted into the profiled hole 111 to seal the mounting hole 110 and prevent the connecting structure 300 from rotating.

[0065] Thus, by setting the mounting hole 110 as an irregular hole 111 and the sealing part 325 as an irregular shaft 3251, after connecting the mounting hole 110 and the sealing part 325, the connecting structure 300 can be prevented from rotating with the structural member 100, thus preventing the connecting structure 300 from rotating and falling off.

[0066] Please refer to the figure. Figure 3 In some embodiments, the second connecting portion 320 includes a baffle 326, the first connecting portion 310 is connected to the baffle 326, and the baffle 326 is configured to clamp the structure 100 with the resilient locking member 322.

[0067] Thus, by clamping the structural member 100 between the baffle 326 and the elastic locking member 322, the tightness between the structural member 100 and the first connecting part 310 can be improved, and the connecting structure 300 can be prevented from falling off.

[0068] Specifically, the second connecting portion 320 includes a baffle 326, the structural member 100 includes a side plate 120, a mounting hole 110 is provided on the side plate 120, and the baffle 326 can be used to abut against the side plate 120 of the structural member 100. One end of the first connecting portion 310 can be connected to the baffle 326, and a sealing portion 325 can be provided on the side wall of the baffle 326. Thus, when the mounting hole 110 is embedded in the sealing portion 325, the baffle 326 can abut against the side plate 120 of the structural member 100, providing a positioning function. Furthermore, after the elastic locking member 322 passes through the mounting hole 110, the baffle 326 can cooperate with the elastic locking member 322 to clamp the side plate 120 of the structural member 100, thereby fixing the connecting structure 300 onto the structural member 100.

[0069] And as Figure 4As shown, in some embodiments, the baffle 326 has a through hole 327 at its center, the first connecting portion 310 has a first air passage 313, and the second connecting portion 320 has a second air passage 324, so that the first air passage 313 and the second air passage 324 can communicate through the through hole 327. Thus, by providing the through hole 327 on the baffle 326, the airflow generated by the structural member 100 can enter the first air passage 313 from the second air passage 324 through the through hole 327, allowing the air pressure switch 200 to collect the air pressure of the structural member 100.

[0070] Please see Figure 3 In some embodiments, the elastic locking member 322 includes a first abutting surface 3221 and a second abutting surface 3222. The second abutting surface 3222 is connected to the side wall of the relief groove 321 through the first abutting surface 3221. The first abutting surface 3221 is inclined outward along the axis away from the connecting structure 300. The second abutting surface 3222 is perpendicular to the axis of the connecting structure 300. A rounded corner structure 3223 is formed at the connection between the first abutting surface 3221 and the second abutting surface 3222.

[0071] Thus, by setting a rounded corner structure 3223 at the connection between the first abutment surface 3221 and the second abutment surface 3222 of the elastic locking member 322, stress concentration can be reduced, the overall strength and stability of the elastic locking member 322 can be improved, and when the mounting hole 110 is inserted, it can smoothly contact the inner wall of the mounting hole 110, avoiding damage to the elastic locking member 322.

[0072] Specifically, the resilient locking member 322 includes a first abutting surface 3221 and a second abutting surface 3222. The first abutting surface 3221 is disposed on the portion of the resilient locking member 322 that protrudes from the relief groove 321. The first abutting surface 3221 can be an inclined surface, meaning it is inclined outwards along the axis away from the connecting structure 300. During the assembly of the second connecting portion 320 into the mounting hole 110, the first abutting surface 3221 abuts against the inner wall of the mounting hole 110, causing the resilient locking member 322 to retract into the relief groove 321.

[0073] The second abutment surface 3222 can be connected to the side wall of the clearance groove 321 through the first abutment surface 3221, and the second abutment surface 3222 is perpendicular to the axis of the connecting structure 300. After the elastic locking member 322 passes through the mounting hole 110, the elastic locking member 322 can extend out of the clearance groove 321 so that the second abutment surface 3222 can abut against the side plate 120 of the structural member 100, thereby enabling the elastic locking member 322 and the baffle 326 to engage the structural member 100.

[0074] A rounded corner structure 3223 is formed at the connection between the first abutting surface 3221 and the second abutting surface 3222. During the process of assembling the second connecting part 320 into the mounting hole 110, the rounded corner structure 3223 can play a guiding role.

[0075] Please see Figure 3 and Figure 5 In some embodiments, the resilient locking member 322 includes a plurality of resilient locking members 322, which are symmetrically arranged about the axis of the connecting structure 300.

[0076] Thus, by symmetrically arranging multiple elastic locking elements 322 about the axis of the connecting structure 300, the ability of the connecting structure 300 to lock the structure element 100 can be improved, preventing the connecting structure 300 from falling off.

[0077] Specifically, the number of elastic elements can be multiple, and is not limited here. Multiple elastic locking elements 322 can be symmetrically arranged about the axis of the connecting structure 300. For example, the number of elastic locking elements 322 can be four, and any two elastic locking elements 322 can be symmetrically locked about the axis of the connecting structure 300.
