Description

Technical Field

[0001] This invention relates to the field of home appliances, and more specifically, to an energy consumption detector for home appliances. Background Technology

[0002] Household appliances refer to all electrical appliances. From a professional perspective, they mainly refer to electrical devices, equipment, and components used to connect and disconnect circuits, change circuit parameters, and control, regulate, switch, detect, and protect circuits or electrical equipment. Household appliances consume a significant amount of electricity during use. Energy consumption detectors can monitor the energy consumption of household appliances. The information obtained is of great significance for power companies to optimize the planning, operation, and management of the power grid, for users to save on electricity consumption and bills, and for the whole society to put the improvement of ecological awareness into concrete actions. However, existing energy consumption detectors for home appliances have the following shortcomings when detecting the energy consumption of home appliances: the energy consumption detector needs to be connected between the power supply and the circuit of the home appliance. When the circuit between the power supply and the home appliance is located in a corner of the wall, it is inconvenient to place the energy consumption detector, making it difficult to connect the circuit between the power supply and the home appliance. In addition, the circuit connection is cumbersome due to the locking method. At the same time, the energy consumption detector is fixedly installed on the wall, making it difficult to disassemble and change to different locations to detect the energy consumption of home appliances in different locations. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is as follows: an energy consumption detector for a household appliance, the structure of which includes a detection host and a disassembly and assembly mechanism. The rear end of the detection host is snapped into the front end of the disassembly and assembly mechanism. The detection host includes a detector, a display screen, a button, and an electrical connection mechanism. The display screen is embedded in the front end of the detector and is electrically connected. The button is provided below the front end of the detector and is electrically connected. The electrical connection mechanism is installed on the upper left side of the detector and is electrically connected. The rear end of the detector is snapped into the front end of the disassembly and assembly mechanism.

[0004] As a further improvement of the present invention, the electrical connection mechanism includes a housing, a detection wire, a winding reel, a spring plate, a rubber sleeve, and a terminal. The bottom of the housing is fixedly installed on the upper left side of the detector, and the detection wire passes through the inside of the housing with a clearance fit. The detection wire is wound around the outside of the winding reel, and a spring plate is provided in the center of the inside of the winding reel. The terminal is electrically connected to the inside of the detector through the detection wire. The rubber sleeve is fixedly installed at the middle of the top of the housing, and the lower end of the terminal is engaged inside the rubber sleeve. The spring plate has a spiral structure and is made of spring steel, which has good resilience and can apply a spiral elastic force inside the winding reel. The rubber sleeve is made of rubber, which has good resilience, and its internal space matches the lower end of the terminal.

[0005] As a further improvement of the present invention, the terminal includes a base, a terminal tube, a conductive sheet, a limiting groove, a compression spring, and a contact sheet. The lower end of the base is snapped into the inside of a rubber sleeve, and the top of the base is fixedly installed in the middle of the bottom of the terminal tube. A conductive sheet is installed in the middle of the inside of the terminal tube. The conductive sheet is electrically connected to the inside of the detector through a detection wire. The limiting groove is fixedly installed inside the terminal tube, and the inside of the limiting groove is connected to the outer end of the contact sheet through a compression spring. The contact sheet is installed in the limiting groove with a clearance fit. The conductive sheet is made of copper, which has the advantages of good conductivity and high cost performance. The conductive sheet is located in the middle of the terminal tube, thereby dividing the inside of the terminal tube into two wiring spaces. There are four limiting grooves, compression springs, and contact sheets, and they are arranged in pairs, symmetrically installed at the upper and lower ends of the two wiring spaces inside the terminal tube.

[0006] As a further improvement of the present invention, the disassembly and assembly mechanism includes a mounting shell, a fixing mechanism, and an adsorption mechanism. The rear end of the detector is engaged and installed inside the front end of the mounting shell, the fixing mechanism is installed on the outer end of the mounting shell, and the adsorption mechanism is installed inside the rear end of the mounting shell. There are two fixing mechanisms, which are symmetrically installed at both ends of the outer side of the mounting shell.

[0007] As a further improvement of the present invention, the fixing mechanism includes a locking screw, a rotating ball, a contact plate, and a buffer pad. The locking screw is threaded through the inner end of the outer side of the mounting housing with a clearance fit. The inner end of the locking screw is provided with a rotating ball, which is installed inside the contact plate with a clearance fit. The inner end of the contact plate is fitted with a buffer pad, and both the contact plate and the buffer pad are located on the inner end face of the mounting housing. The contact plate abuts against the outer side of the rear end of the detector through the buffer pad. There are three locking screws and three rotating balls, which are vertically distributed on the contact plate.

[0008] As a further improvement of the present invention, the adsorption mechanism includes a back plate, a positioning tube, a pressing airbag, a telescopic hose, and a suction cup. The back plate is fixedly installed inside the rear end of the mounting shell, and the positioning tube is fixedly installed on the back plate. The positioning tube is provided with a pressing airbag inside. The rear end of the pressing airbag is connected to a telescopic hose and is continuously connected therethrough. The rear end of the telescopic hose is provided with a suction cup and is continuously connected therethrough. The telescopic hose and the suction cup are both located at the rear end of the back plate. There are four of each of the positioning tube, pressing airbag, telescopic hose, and suction cup, distributed near the four corners of the back plate. The telescopic hose has a pleated structure and is made of rubber, which has good resilience.

[0009] The beneficial effects of this invention are as follows: 1. When the circuit of the incoming power supply and home appliances is connected into the junction box, the compression spring applies elastic squeezing force to the contact piece, so that the contact pieces at the upper and lower ends can elastically abut against the circuit of the incoming power supply or home appliances, thereby improving the firmness and convenience of the circuit connection of the incoming power supply or home appliances. 2. Pull the terminal out of the rubber sleeve by pulling it. During the pulling process, the spring plate applies a spiral force inside the reel, causing the reel to rotate automatically. The detection wire can adaptively extend and retract between the detector and the terminal. The terminal can be moved to the corner of the wall to connect the circuit between the incoming power supply and home appliances, avoiding dead angles in the detection connection. 3. The suction cup is attached to the wall, the telescopic hose is extended and retracted, and the air bladder is pressed to completely expel the air inside the suction cup, so that the suction cup can be vacuum-adhere to the wall, improving the firmness of the mounting shell on the wall and making it easy to disassemble and change the position of the mounting shell for installation. This allows the detector to detect the energy consumption of home appliances in different locations. 4. Insert the rear end of the detector into the mounting housing, then rotate the locking screw to drive the rotating ball to rotate inside the contact plate, ensuring that the locking screw can push the contact plate to move. The contact plates and buffer pads on both sides abut against the left and right end faces of the detector, ensuring that the detector is firmly locked inside the mounting housing for stable energy consumption detection of home appliances.

Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: Example

[0019] As attached Figure 1 To be continued Figure 6 As shown: This invention discloses an energy consumption detector for a household appliance, comprising a detection host C and a disassembly / assembly mechanism G. The rear end of the detection host C is snapped into the front end of the disassembly / assembly mechanism G. The detection host C includes a detector c5, a display screen c8, a button c3, and an electrical connection mechanism c1. The display screen c8 is embedded in and electrically connected to the front end of the detector c5. The button c3 is located below the front end of the detector c5 and is electrically connected. The electrical connection mechanism c1 is installed on the upper left side of the detector c5 and is electrically connected. The rear end of the detector c5 is snapped into the front end of the disassembly / assembly mechanism G.

[0020] The electrical connection mechanism c1 includes a housing c14, a detection wire c12, a winding reel c19, a spring plate c15, a rubber sleeve c16, and a terminal c11. The bottom of the housing c14 is fixedly installed on the upper left side of the detector c5, and the detection wire c12 passes through the inside of the housing c14 with a clearance fit. The detection wire c12 is wound around the outside of the winding reel c19, and the spring plate c15 is provided in the center of the inside of the winding reel c19. The terminal c11 is electrically connected to the inside of the detector c5 through the detection wire c12. The rubber sleeve c16 is fixedly installed at the top middle of the housing c14, and the lower end of the terminal c11 is engaged inside the rubber sleeve c16. The spring plate c15 has a spiral structure and is made of spring steel, which has good resilience. It can apply spiral elastic force inside the winding reel c19, causing the winding reel c19 to automatically rotate and automatically wind and unwind the detection wire c12. This allows the detection wire c12 to adaptively extend and retract between the detector c5 and the terminal c11, ensuring a tight connection between the terminal c11 and the detector c5. The rubber sleeve c16 is made of rubber and has good resilience. Its internal space matches the lower end of the terminal c11, allowing the lower end of the terminal c11 to elastically engage inside the rubber sleeve c16 and be quickly removed from it. The terminal c11 can be moved independently, allowing it to be moved to a corner of the wall to connect the circuit between the incoming power supply and home appliances, avoiding dead angles in the detection connection.

[0021] The terminal c11 includes a base 1z, a terminal tube 1g, a conductive sheet 1s, a limiting groove 1u, a compression spring 1t, and a contact sheet 1y. The lower end of the base 1z is engaged inside the rubber sleeve c16, and the top of the base 1z is fixedly installed at the bottom middle of the terminal tube 1g. The conductive sheet 1s is installed in the middle of the terminal tube 1g. The conductive sheet 1s is electrically connected to the detector c5 through a detection wire c12. The limiting groove 1u is fixedly installed inside the terminal tube 1g, and the inside of the limiting groove 1u is connected to the outer end of the contact sheet 1y through the compression spring 1t. The contact sheet 1y is installed inside the limiting groove 1u with a clearance fit. The conductive sheet 1s is made of copper, which has the advantages of good conductivity and high cost performance. The conductive sheet 1s is located in the middle of the wiring tube 1g, thus dividing the inside of the wiring tube 1g into two wiring spaces, which are respectively connected to the circuits of the incoming power supply and the home appliances. This allows the detector c5 to be connected between the circuits of the incoming power supply and the home appliances, thereby detecting the energy consumption of the home appliances. There are four limiting grooves 1u, compression springs 1t, and contact pieces 1y, which are arranged in pairs and symmetrically installed at the upper and lower ends of the two wiring spaces inside the wiring tube 1g. The compression springs 1t apply elastic compression force to the contact pieces 1y, so that the contact pieces 1y at the upper and lower ends can elastically abut against the circuits of the incoming power supply or the home appliances, improving the firmness and convenience of the circuit connection of the incoming power supply or the home appliances. The specific usage and function of this embodiment are as follows: In this invention, when detecting the energy consumption of home appliances, the disassembly and assembly mechanism G is positioned and installed according to the circuit location of the home appliance to be detected. Then, the terminal c11 on the detection host C is connected between the power supply and the circuit of the home appliance. The conductive piece 1s is located in the middle of the wiring tube 1g, thus dividing the inside of the wiring tube 1g into two wiring spaces, which are respectively connected to the circuits of the power supply and the home appliance. This allows the detector c5 to be connected between the power supply and the circuit of the home appliance, thereby detecting the energy consumption of the home appliance. When the power supply and the circuit of the home appliance are connected and enter the wiring tube 1g, the compression spring 1t applies an elastic squeezing force to the contact piece 1y, so that the contact pieces 1y at the upper and lower ends can contact the power supply or the circuit of the home appliance. The flexible contact mechanism enhances the robustness and convenience of circuit connections for incoming power or home appliances. When the circuit to be tested is in a corner of the wall, pulling terminal c11 extends it from inside the rubber sleeve c16. During this process, a spiral force is applied inside the reel c19 via spring c15, causing the reel c19 to automatically rotate and rewind the detection lead c12. This allows the detection lead c12 to adaptively extend and retract between the detector c5 and terminal c11, ensuring a tight connection between terminal c11 and detector c5. Consequently, terminal c11 can be moved to a corner of the wall to connect the circuit between the incoming power and home appliances, avoiding dead angles in the detection connection. Example

[0022] As attached Figure 5 To be continued Figure 7 As shown: The disassembly and assembly mechanism G includes a mounting shell g1, a fixing mechanism g4, and an adsorption mechanism g6. The detector c5 is engaged and installed inside the front end of the mounting shell g1 at its rear end. The fixing mechanism g4 is installed on the outer end of the mounting shell g1, and the adsorption mechanism g6 is installed inside the rear end of the mounting shell g1. Two fixing mechanisms g4 are provided and are symmetrically installed at both ends of the outer side of the mounting shell g1. The fixing mechanisms g4 on both sides can firmly lock the rear end of the detector c5 inside the front end of the mounting shell g1, making it easy to remove and install the detector c5 from the inside of the mounting shell g1.

[0023] The fixing mechanism g4 includes a locking screw g45, a rotating ball g42, a contact plate g43, and a buffer pad g49. The locking screw g45 is threaded through the outer end of the mounting shell g1 with a clearance fit. The inner end of the locking screw g45 is provided with a rotating ball g42, which is installed inside the contact plate g43 with a clearance fit. The inner end of the contact plate g43 is fitted with a buffer pad g49, and both the contact plate g43 and the buffer pad g49 are located on the inner end face of the mounting shell g1. The contact plate g43 abuts against the outer side of the rear end of the detector c5 through the buffer pad g49. There are three locking screws g45 and three rotating balls g42, which are vertically distributed on the contact plate g43. The rotation of the three locking screws g45 drives the rotating balls g42 to rotate inside the contact plate g43, ensuring that the locking screws g45 can push the contact plate g43 to move. This allows for adjustment of the position of the contact plate g43 in the upper, middle and lower positions inside the mounting shell g1, ensuring that the contact plate g43 can firmly lock the detector c5 inside the mounting shell g1.

[0024] The adsorption mechanism g6 includes a back plate g67, a positioning tube g62, a pressing airbag g69, a telescopic hose g65, and a suction cup g63. The back plate g67 is fixedly installed inside the rear end of the mounting shell g1, and the positioning tube g62 is fixedly installed on the back plate g67. The positioning tube g62 is provided with a pressing airbag g69 inside. The rear end of the pressing airbag g69 is connected to the telescopic hose g65 and is connected through it. The rear end of the telescopic hose g65 is provided with a suction cup g63 and is connected through it. The telescopic hose g65 and the suction cup g63 are both located at the rear end of the back plate g67. The positioning tube g62, pressing airbag g69, telescopic hose g65, and suction cup g63 are each provided in four parts, distributed near the four corners of the back plate g67. The telescopic hose g65 has a pleated structure and is made of rubber, which has good resilience. By squeezing the airbag g69 and extending the telescopic hose g65, the air inside the suction cup g63 can be completely expelled, allowing the suction cup g63 to be vacuum-adhere to the wall. This improves the firmness of the mounting shell g1 on the wall and makes it easy to disassemble and change the position of the mounting shell g1 for installation. This allows the detector c5 to perform energy consumption detection on home appliances in different locations. The specific usage and function of this embodiment are as follows: In this invention, when the disassembly and assembly mechanism G is positioned and installed on the wall around the appliance being tested, it adheres to the wall via suction cup g63. Then, the mounting shell g1 is pushed against the wall, causing the telescopic hose g65 to extend or retract. Finally, by pressing the airbag g69, all the air inside the suction cup g63 is expelled, allowing the suction cup g63 to vacuum-adhere to the wall. This improves the stability of the mounting shell g1 and facilitates its removal and repositioning, enabling the detector c5 to perform energy consumption testing on appliances in different locations. After the position is fixed, the rear end of the detector c5 is inserted into the mounting housing g1. Then, the rotating ball g42 is rotated inside the contact plate g43 by rotating the locking screw g45, ensuring that the locking screw g45 can push the contact plate g43 to move. The position of the contact plate g43 in the upper, middle and lower positions inside the mounting housing g1 is adjusted by the three locking screws g45. The left and right end faces of the detector c5 are pressed against the contact plates g43 and the buffer pads g49 on both sides to ensure that the detector c5 is firmly locked inside the mounting housing g1 for stable energy consumption detection of home appliances. Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
