[0043] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0044] Embodiment 1

[0045] This embodiment provides a drying channel detection device, which can detect the drying channel of a washing machine.

[0046] like Figure 1 and Figure 2 As shown, the drying channel detection device of a washing machine provided in this embodiment includes: a device bottom plate 1, a drying channel profiling tooling 2, a detection drive mechanism 3, a rocker arm 4 and a detection device 5.

[0047] The device bottom plate 11 is a rectangular plate or other shaped plate, and the oven profiling tooling 2, the detection drive mechanism 3, the rocker arm 4 and the detection device 5 are all arranged on the device bottom plate 1, so that the detection device as a whole can be carried and moved. A first through hole is opened on the device bottom plate 11, and the oven motor can pass through the first through hole.

[0048] The drying tunnel profiling tool 2 is used to support the drying tunnel of the washing machine (hereinafter referred to as drying tunnel), that is, the drying tunnel can be placed on the drying tunnel profiling tool 2 for testing. A second through hole 23 for accommodating the drying tunnel motor is provided at one end of the drying tunnel profiling tool 2, and the second through hole 23 corresponds to the position of the first through hole. The side wall of the second through hole 23 is provided with an electrical connection contact, which is used to electrically contact with the power supply end of the drying tunnel motor after the drying tunnel motor is inserted into the second through hole 23, so as to supply power to the drying tunnel motor, and the drying tunnel motor drives the impeller to rotate.

[0049] The detection drive mechanism 3 is connected to the rocker arm 4 and is used to drive the rocker arm 4 to move. In the state to be detected, the detection drive mechanism 3 drives the rocker arm 4 to move to the initial position, such as Figure 1 Located at the edge of the device bottom plate 1; during the detection process, the detection drive mechanism 3 drives the rocker arm 4 to move.

[0050] The detection device 5 is connected to the rocker arm 4 and moves with the rocker arm 4. The rocker arm 4 drives the detection device 4 to move above the drying tunnel motor for detection. The detection device 5 can be used to detect the rotation speed of the impeller, thereby determining whether the drying tunnel motor is normal according to the rotation speed of the impeller, or to detect the wind speed driven by the impeller during rotation, and can also be used to determine whether the drying tunnel motor is normal, and can also determine whether the impeller is normal.

[0051] Specifically, the detection device 5 can be a photoelectric sensor, a capacitive sensor, a laser rotation speed sensor, etc. The detection device 5 in this embodiment is a Hall effect sensor, which is used to detect the rotation speed of the drying tunnel motor.

[0052] The working process of the above detection device is as follows: first check whether each part of the detection device is working normally, then place the drying tunnel 6 on the drying tunnel profiling tooling 2 and lock it, then start the detection drive mechanism 3 to drive the rocker arm 4 to move, and drive the detection device 5 to move above the drying tunnel motor. After the detection device 5 moves into place, start the drying tunnel motor and drive the impeller to rotate. The detection device 5 collects the rotation state data of the impeller and determines whether the drying tunnel motor is normal. After the detection is completed, the detection drive mechanism 3 drives the rocker arm 4 to move to the initial position.

[0053] The technical solution provided in this embodiment is that the detection device adopts a device bottom plate and a drying tunnel profiling tooling, a detection drive mechanism, a rocker arm and a detection device arranged on the device bottom plate, the device bottom plate is provided with a first through hole for the drying tunnel motor to pass through; the drying tunnel profiling tooling is used to support the drying tunnel of the washing machine; one end of the drying tunnel profiling tooling is provided with a second through hole for accommodating the drying tunnel motor, and the second through hole corresponds to the position of the first through hole; the side wall of the second through hole is provided with an electrical connection contact, which is used to electrically contact the power supply end of the drying tunnel motor after the drying tunnel motor is inserted into the second through hole; the detection drive mechanism is connected to the rocker arm, which is used to drive the rocker arm to move; the detection device is connected to the rocker arm, and can move with the rocker arm to the second through hole to detect the drying tunnel motor, thereby realizing intelligent detection of the drying tunnel motor, solving the problems of low efficiency, low accuracy and high cost of manual visual inspection in the traditional solution, and can better meet the needs of mass production and realize high-precision and high-speed production.

[0054] The above oven profile tooling can adapt to ovens of various structures, and can also be appropriately adjusted according to ovens of different structures. Figures 3 to 5 Taking the oven 6 shown in the figure as an example, an implementation method of an oven tunnel profiling tool 2 is provided:

[0055] like Figures 3 to 5 As shown, the drying tunnel 6 includes a curved tube-shaped drying tunnel shell 61, a drying tunnel motor 62, an impeller (not marked in the figure), and a heating tube 63. The drying tunnel shell 61 includes an upper shell and a lower shell connected together, and the space enclosed by the upper shell and the lower shell serves as an air passage. One end of the drying tunnel shell 61 serves as an air inlet 611, and the other end serves as an air outlet 612.

[0056] The drying tunnel motor 62 and the impeller are arranged at the air inlet 611. The drying tunnel motor 61 drives the impeller to rotate, so that the external air enters the airway from the air inlet 611 and flows along the airway to be discharged from the air outlet 612 (such as Figure 5 ) to provide circulating hot air.

[0057] The heating pipe 63 is arranged in the drying channel housing 61, and is used to heat the air flowing through the air channel. After the heated hot air is discharged from the air outlet 612, it enters the drum of the washing machine to dry the clothes.

[0058] In the above embodiment, one end of the drying tunnel 6 is approximately circular, and the other end is a long strip structure, and the air outlet 612 is widened. Figures 6 to 8 As shown, the oven tunnel profiling tool 2 in this embodiment includes: a motor bearing portion 21 and an airway bearing portion 22. The shape of the motor bearing portion 21 matches the shape of the end portion of the oven tunnel 6 for mounting the oven tunnel motor, and is used to support the end portion. The airway bearing portion 22 extends along the length direction of the device bottom plate 1, and is used to support the long strip portion of the oven tunnel 6.

[0059] The motor bearing portion 21 is provided with a second through hole 23 , and the drying tunnel motor 62 is inserted into the second through hole 23 and exposed from the first through hole.

[0060] In order to improve the reliability and accuracy of the detection process, the oven profiling tool 2 can be fixed on the device bottom plate 1. One implementation is: bolt holes 221 are set on the airway bearing part 22, and bolts are fixed to the device bottom plate 1 through the corresponding bolt holes 221. Of course, bolt holes can also be opened on the motor bearing part 21 to connect with the device bottom plate 1.

[0061] On the basis of the above technical solution, the upper surface of the airway bearing part 22 is recessed downward to form a receiving groove, and a support block 24 of a preset height is embedded in the receiving groove. The height of the support block 24 can be set according to the structure of the drying tunnel 6 to meet the needs of drying tunnels 6 of different shapes. The support block 24 can be provided with the above bolt hole 221, and the support block 24 and the drying tunnel profiling tooling 2 can be fixed on the device bottom plate 1 at the same time, thereby reducing the number of assembly points, thereby reducing the assembly workload and improving the detection efficiency.

[0062] Furthermore, the support block 24 may be in the shape of a cuboid, and its top surface is concave downward to form an assembly groove, and the assembly groove and the top surface of the support block 24 form a step-like structure, which can not only support the drying tunnel 6, but also position and limit the drying tunnel 6. The depth and width of the assembly groove can be specifically limited according to the structure of the drying tunnel 6.

[0063] Furthermore, the sensor 25 is assembled in the assembly groove of the support block 24. The sensor 25 is used to sense the drying tunnel 6 and can identify whether there is a drying tunnel 6 placed on the drying tunnel profiling tooling 2. The sensor 25 can be a proximity switch, a photoelectric switch and other devices. This embodiment uses a proximity switch. When the drying tunnel 6 is placed on the drying tunnel profiling tooling 2, the sensor 25 sends corresponding data, which can be transmitted to the controller. After the controller learns that the drying tunnel 6 is in place, it can start the detection drive mechanism 3 to act; or the controller sends a prompt message to manually start the detection drive mechanism 3.

[0064] On the basis of the above technical solution, the second through hole 23 on the drying tunnel profiling tool 2 can also be set according to the drying tunnel motor 62. This embodiment takes a drying tunnel motor 62 as an example. Fig. 9 and Fig.10 As shown, the motor winding 622 is arranged at one end of the motor body 621, the motor winding 622 includes a stator and a rotor, the motor output shaft 623 is connected to the rotor, and the motor output shaft 623 is also connected to the impeller. The front of the motor body 621 is roughly rectangular, and the four top corners of the motor body 621 at this end of the motor winding 622 are hollowed out to form a gap 624, which can reduce the silicon steel sheet material, thereby reducing the production cost.

[0065] Accordingly, this embodiment provides an implementation of the second through hole 23, such as Fig.11 and Fig.12 As shown, the second through hole 23 includes a main body area 231 and a convex area 232 extending outward from one end of the main body area 231 to accommodate the motor winding 622. The width of the convex area 232 is smaller than the width of the main body area 231 to adapt to the structure of the four top corners of the motor body 621 being hollowed out.

[0066] Furthermore, the inner walls of the two edges of the convex area 232 are arc-shaped, forming an arc-shaped avoidance area 233 for avoiding the corners of the motor body 621 to avoid damaging the drying tunnel motor 62. Similarly, the inner walls of the multiple edges of the main area 231 can also be arc-shaped, forming an arc-shaped avoidance area 233.

[0067] One implementation is that the top surface of the motor bearing portion 21 and the inner wall of the main body area 231 are transitioned through a downwardly inclined slope 234. The slope 234 can guide the drying tunnel motor 62 during the insertion into the second through hole 23, thereby reducing the alignment time and improving efficiency.

[0068] Furthermore, the top surface of the motor bearing portion 21 and the convex area 232 are transitioned through a sunken step surface 235, which can be used to avoid the structure at the corresponding position of the drying tunnel motor 62, or to facilitate the removal of the drying tunnel.

[0069] On the basis of the above technical solution, the inner wall of one side of the main body area 231 is expanded outward to form an electrical connection area, and the electrical connection contact 26 is located in the electrical connection area. One implementation method is: the drying tunnel motor 26 is a DC motor, and the number of the electrical connection contact 26 is two, which are arranged vertically at intervals. The electrical connection contact 26 includes: an electrical contact and an elastic member connected to the rear end of the electrical contact.

[0070] When the drying tunnel motor 62 is inserted into the second through hole 23, it contacts the electric contact and presses the electric contact outward, compressing the elastic member and accumulating elastic potential energy. The rebound force generated by the compression of the elastic member causes the electric contact to be pressed against the electrical interface of the drying tunnel motor 62, so that the electric contact and the electrical interface of the drying tunnel motor 62 maintain good electrical contact.

[0071] Based on the above technical solution, this embodiment describes the implementation method of the detection drive mechanism 3:

[0072] like Figure 1 , Figure 2 , Fig.13 , Fig.14 and Fig.15As shown, the detection drive mechanism includes: a rotation drive assembly 31 and a first vertical drive assembly 32. The rotation drive assembly 31 is arranged on the device bottom plate 1, and the first vertical drive assembly 32 is connected to the rotation drive assembly 31. The rotation drive assembly 31 is used to drive the first vertical drive assembly 32 to rotate horizontally.

[0073] The rocker arm 4 is connected to the first vertical driving assembly 32, and the first vertical driving assembly 32 is used to drive the rocker arm 4 to move vertically, thereby raising or lowering the rocker arm 4 and driving the detection device 5 to rise and fall.

[0074] In the above solution, the detection device 5 is driven to rotate horizontally and move vertically by cooperating with the rotation drive assembly 31, the first vertical drive assembly 32 and the rocker arm 4.

[0075] During the detection process, the first vertical drive assembly 32 is used to drive the rocker arm 4 and the detection device 5 to rise above the drying tunnel 6. Then, the rotary drive assembly 31 is used to drive the rocker arm 4 and the detection device 5 to rotate horizontally to the top of the drying tunnel motor 62. Then, the first vertical drive assembly 32 is used to drive the rocker arm 4 and the detection device 5 to descend until the detection device 5 reaches the target position, so as to detect the drying tunnel motor 62.

[0076] A specific implementation manner: the rotation drive assembly 31 may include a housing 311 and a motor, a gear set and a bearing 312 disposed in the housing, wherein the output end of the motor is connected to one end of the gear set, and the other end of the gear set is connected to the first vertical drive assembly 32 to drive the first vertical drive assembly 32 to rotate horizontally. The bearing 312 is disposed between the first vertical drive assembly 32 and the housing.

[0077] The first vertical drive assembly 32 can be implemented by a motor, a hydraulic cylinder, a pneumatic cylinder, etc. Taking a pneumatic cylinder as an example, the top of the telescopic rod of the pneumatic cylinder is connected to the rocker arm 4, and the movement of the pneumatic cylinder drives the rocker arm 4 to rise and fall.

[0078] Furthermore, a reinforcing plate group 35 may be provided on the first vertical drive assembly 32, and the reinforcing plate group 35 includes two right-angled triangular plates and two rectangular plates. The first rectangular plate is parallel to the vertical surface of the first vertical drive assembly 32, and the second rectangular plate is vertically connected to the bottom end of the first rectangular plate. The two right-angled triangular plates are respectively located on both sides of the rectangular plate, and the two right-angled sides of the right-angled triangular plate are respectively connected to the first rectangular plate and the second rectangular plate. The use of the above-mentioned reinforcing plate group 35 can improve the stability of the first vertical drive assembly 32 during the horizontal rotation process.

[0079] On the basis of the above technical solution, a second vertical drive assembly 33 and a connecting shaft 34 can also be used. The second vertical drive assembly 33 is arranged on the rocker arm 4 and is located at the end away from the first vertical drive assembly 32. One end of the connecting shaft 34 is connected to the second vertical drive assembly 33, and the other end is connected to the detection device 5. The second vertical drive assembly 33 is used to drive the connecting shaft 34 and the detection device 5 to move vertically. The second vertical drive assembly 33 can be implemented by a motor, a hydraulic cylinder, a cylinder, etc. The second vertical drive assembly 33 is used to supplement the height that the detection device 5 can be raised and lowered, so as to adapt to more drying tunnels 6.

[0080] On the basis of the above technical solution, a data processor 7 is further used, which is arranged on the device bottom plate 1 and is electrically connected to the detection device 5. The data processor 7 can be a controller, such as a programmable logic controller PLC. The data processor 7 is used to collect data from the detection device 5 and the signal of the sensor 25, and process them, and is also used to control the detection drive mechanism 3.

[0081] A display unit 8 is also used and is disposed on the upper surface of the data processor 7. The display unit 8 may be a display screen and is electrically connected to the data processor 7. The data processor 7 may display the processed data through the display unit 8, such as the rotation speed of the drying tunnel motor 62, the operating state of the detection drive mechanism 3, the fault state, etc. Alternatively, the display unit 8 is a display instrument, which is directly electrically connected to the detection device 5 and displays the rotation speed of the drying tunnel motor.

[0082] Furthermore, an indicator light 91 is provided on the bottom plate 1 of the device, and the indicator light 91 is electrically connected to the data processor 7. When the data processor 7 determines that the drying tunnel motor 62 is abnormal, the indicator light 91 is turned on. Alternatively, a multi-color indicator light is used, and when the drying tunnel motor 62 is normal, the indicator light is green; when the drying tunnel motor 62 is abnormal, the indicator light is red; during the detection process, the indicator light is yellow or white, etc.

[0083] A buzzer 92 can also be used, which is arranged on the device bottom plate 1 and electrically connected to the data processor 7. When the data processor 7 determines that the drying tunnel motor 62 is abnormal, the buzzer 92 is controlled to emit an audio signal to give a voice prompt to the operator.

[0084] Embodiment 2

[0085] This embodiment provides a detection method for the drying channel of a washing machine on the basis of the above technical solution, which can be implemented using the detection device in the above embodiment. The method is specifically implemented by the data processor 7 in the above detection device and can be implemented by software.

[0086] like Fig.16 As shown, the drying tunnel detection method provided in this embodiment includes:

[0087] Step 101: When it is confirmed that a drying oven is placed on the drying oven profiling tooling, the detection drive mechanism is controlled to start, and the rocker arm and the detection device are driven to move to the top of the drying oven motor.

[0088] Confirming that a drying tunnel is placed on the drying tunnel profiling tooling may specifically include: first acquiring detection data of a sensor on the drying tunnel profiling tooling, and then confirming whether a drying tunnel is placed on the drying tunnel profiling tooling according to the detection data of the sensor.

[0089] Specifically, the drying tunnel 6 is first placed on the drying tunnel profiling tool 2, and the position of the drying tunnel is corrected by the profiling tool, and the detection is performed in a positive posture. The sensor 25 sends the detection data to the data processor 7, and the data processor 7 confirms whether the drying tunnel 6 is placed on the drying tunnel profiling tool 2. After confirming that there is a drying tunnel 6, the data processor 7 controls the detection drive mechanism 3 to start, driving the rocker arm 4 and the detection device 5 to move above the drying tunnel motor 62.

[0090] Specifically, referring to the above content, the data processor 7 can control the rotation drive assembly 31, the first vertical drive assembly 32 and the second vertical drive assembly 33 to operate in sequence.

[0091] Step 102: Acquire detection data of the detection device, and determine whether the drying tunnel motor is normal according to the detection data.

[0092] When the detection device 5 is a device for detecting the rotational speed, the data processor 7 processes the data sent by the detection device 5 to obtain the rotational speed of the drying tunnel motor 62, and compares it with the preset standard rotational speed data. When the difference between the detected rotational speed and the standard rotational speed data is within the preset range, it is determined that the rotational speed of the drying tunnel motor 62 is normal; if it is not within the preset range, it is determined that the rotational speed of the drying tunnel motor 62 is abnormal.

[0093] Step 103: If it is determined that the drying tunnel motor is abnormal, an abnormality message is issued.

[0094] The abnormal information can be reflected by at least one of the display element 9 , the indicator light 91 , and the buzzer 92 .

[0095] The detection method provided in this embodiment, when it is confirmed that a drying oven is placed on the drying oven profiling tooling, controls the detection drive mechanism to start, drives the rocker arm and the detection device to move to the top of the drying oven motor; obtains the detection data of the detection device, and determines whether the drying oven motor is normal according to the detection data; if it is determined that the drying oven motor is abnormal, an abnormal information is issued, thereby realizing intelligent detection of the drying oven motor, solving the problems of low efficiency, low accuracy and high cost of manual visual inspection in the traditional solution, and better meeting the needs of mass production, and realizing high-precision and high-speed production.

[0096] Moreover, the above scheme can accurately distinguish according to different speed standard thresholds, with wider adaptability and higher precision. The above scheme sends a signal through the sensor 25 to monitor the oven positioning information under the premise of ensuring personnel safety, accurately control the detection time point, and the performance standard parameters can be configured according to the model to achieve the advantage of accuracy.

[0097] The above solution uses automation technology to efficiently and accurately detect the rotation speed of the drying tunnel motor impeller to ensure that the performance meets quality requirements. Its application will help improve production efficiency, reduce production costs, improve product quality and safety, and provide strong support for the development of washing machines.
