[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.
[0042] Combination Figure 1-6As shown, an embodiment of the present disclosure provides an external water intake device for a refrigerator.
[0043] As a common household appliance, refrigerators are used to make cold water. Common drinking cold water is obtained by mechanically taking water from the refrigerator door. Specifically, the refrigerator door is composed of an internal kettle and a water pressure tongue outside the door.
[0044] For refrigerators with mechanical external water intake from the door, workers are required to test whether the water intake function is qualified during mass production. The door needs to be hung on the cabinet and all parts installed before testing can be carried out.
[0045] The conventional testing method is to hang the door on the box body, that is, to assemble it on the box body through hinge assembly, and then install water intake components such as a kettle and a tongue depressor for testing.
[0046] In actual production, considering the production process and rhythm on site, refrigerators are constantly rolling on the conveyor belt, and various parts need to be installed at different stations during the process. If all refrigerators are off the line before unified testing, it will be time-consuming and labor-intensive. Therefore, workers are required to complete the inspection within a limited time when the refrigerator passes the inspection station.
[0047] However, if any component is found to have a problem during the inspection, it cannot be replaced in time. In addition, since the refrigerator is always on a moving conveyor belt, it will also affect the state of the refrigerator, resulting in deviations in the results.
[0048] The refrigerator door external water extraction detection device provided by the embodiment of the present disclosure comprises a door body, a tool frame, a first stopper and a second stopper assembly. The door body is equipped with an external water extraction device, and the door body comprises an upper decorative strip and a lower decorative strip opposite to each other, and the upper decorative strip and the lower decorative strip are respectively provided with an upper shaft sleeve and a lower shaft sleeve; the tool frame comprises a box frame body and a stopper shaft fixedly connected, and the stopper shaft is located above the box frame body; the first end of the first stopper is rotatably sleeved on the stopper shaft, and the second end opposite to the first end is provided with a hinge shaft, and the hinge shaft is inserted in the upper shaft sleeve to fix the upper decorative strip; the second stopper assembly is fixed to the lower part of the box frame body, and the second stopper assembly comprises a positioning shaft, and the positioning shaft is inserted in the lower shaft sleeve to fix the lower decorative strip.
[0049] The novel external water intake detection method provided in the present application can complete the water intake detection step at the door body station by simulating the state of the door body being assembled on the box body through tooling, and the door body that passes the detection can be directly assembled to the box body and run offline normally.
[0050] Specifically, during the inspection, the door body equipped with the external water intake device is moved to the tooling frame. The lower shaft sleeve of the lower decorative strip of the door body is sleeved on the positioning shaft of the frame body to limit and fix the lower part of the door body. The upper decorative strip of the door body is provided with an upper shaft sleeve. By moving the hinge shaft of the first limiting member on the frame body, the hinge shaft can be inserted into the upper shaft sleeve to fix the upper part of the door body and prevent the door body from tipping over.
[0051] Since the door body is foamed at a separate station, it is transferred to the assembly line after foaming and hung on the box by workers. Therefore, the water extraction in the door body simulation test is not limited by the time of the assembly line, and the operation is more sufficient. And if problems are found, they can be replaced in time.
[0052] In addition, the foamed door body itself also needs to be placed in the transfer area. When the box reaches the door hanging station on the assembly line, the workers will pull the door body over. Therefore, no additional space is required for door body inspection. It is only necessary to change the original shelf for placing the door body to the tooling of the present invention.
[0053] Optionally, the frame body is provided with a first through hole so that the hinge shaft can be inserted into the first through hole; the distance between the first through hole and the limit shaft is equal to the distance between the first end and the second end of the first limit member, and the rotation angle range of the hinge shaft relative to the limit shaft is [0°, 90°].
[0054] When the door body is in a non-detection state, the hinge shaft is inserted into the first through hole of the door body to protect the hinge shaft and avoid interference with the hinge shaft during the placement of the door body.
[0055] Optionally, the refrigerator door outer water extraction detection device also includes a stopper, which is made of metal and fixed to the door body, and is used to be fixed to the door seal of the door body by magnetic attraction to prevent the door body from rotating on the tooling frame.
[0056] The stopper can be magnetically engaged with the door seal to fix the door body, thereby better improving the stability of the door body.
[0057] Optionally, a second through hole is formed in the lower decorative strip of the door body, and the second limiting assembly further includes a fixed shaft adapted to the second through hole, and a line connecting the fixed shaft and the positioning shaft is parallel to the upper decorative strip.
[0058] The fixed shaft protrudes upward from the ground, and the second through hole on the door body can be placed and fixed on the fixed shaft from top to bottom, thereby fixing the lower decorative strip of the door body. The connecting line of the fixed shaft and the positioning shaft is parallel to the upper decorative strip, which can avoid the problem of rotational deviation of the door body around the positioning shaft.
[0059] Optionally, the lower decorative strip is further provided with a raised portion, the raised portion is raised downward from the lower decorative strip, the second limit assembly includes a third through hole, the third through hole is adapted to the raised portion, and the raised portion, the fixed shaft and the positioning shaft are located on the same horizontal line. In this way, not only the fixing support of the lower decorative strip of the door body is improved, but also the door body can be prevented from rotating.
[0060] Optionally, the box frame body includes a circular frame, a bottom frame and an upper frame. The circular frames include two or more, adjacent circular frames are parallel to each other, and the circular frames are equal in width and height to the door body; the bottom frame includes a first guide rail and a second guide rail that are parallel to each other, and the first guide rail and the second guide rail are respectively located at two bottom corners of the circular frame; the upper frame is fixedly connected to the upper corner of the circular frame, the upper frame is parallel to the first guide rail, the first limiter is located at the upper frame, and the second limiter is fixedly connected to the first guide rail.
[0061] Multiple return frames can be used to place one or more door bodies to be tested. Multiple refrigerator door water extraction detection devices can be tested simultaneously, which can improve the detection efficiency and save space.
[0062] Optionally, the second limiting assembly includes a base, a first set, a second set and a gasket. The first guide rail is also fixed with a limiting plate 6, the limiting plate 6 has a preset distance with the return frame, and the base is fixed on the limiting plate 6; the first set includes an integrally formed threaded column and a cylindrical portion, the threaded column is fixedly connected to the threaded hole on the base; the second set includes an integrally formed cap and a brim, the cap is hollow in the middle and is sleeved on the periphery of the cylindrical portion, the cap is used for limiting and fixing; the gasket is fixedly connected to the brim, the gasket includes a fourth through hole and a third through hole, the fourth through hole is sleeved on the periphery of the cap, and the third through hole is used for limiting and engaging with the convex ring at the bottom of the door body; wherein the cylindrical portion and the cap together form a positioning axis, and the height of the cylindrical portion is higher than the height of the cap.
[0063] The cylindrical part is used to limit the lower sleeve of the lower decorative strip. The cap is arranged on the outer circumference of the cylindrical part and is located inside the lower sleeve. The difference between the outer diameter of the cap and the inner diameter of the cylindrical part is less than 0.5mm, so that the cap can fit on the inner wall surface of the lower sleeve to prevent the positioning shaft from relative displacement in the lower sleeve and affect the detection of the door body.
[0064] Optionally, the second limiting assembly also includes a third kit, the third kit includes a screw hole column and a fifth through hole, the fifth through hole is sleeved on the cylindrical part and fixed with the sleeve cap, and the screw hole column is threadedly fixedly connected to the base by screws.
[0065] The provision of the third set of components can prevent the sleeve cap from rotating circumferentially relative to the lower sleeve, thereby further improving the stability of the door body.
