Detailed Description

Various exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is not intended to limit the utility model, its application, or uses. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art. It should be noted that: the relative arrangement of parts and steps, numerical expressions and numerical values set forth in these embodiments should be construed as merely exemplary, and not as limiting, unless otherwise specifically stated.

As shown in fig. 1, in one aspect of the present invention, a revolving door testing device for a kitchen appliance includes a testing table 2, a rotating arm 3 rotatably disposed on the testing table 2, a connecting mechanism 4 for connecting the rotating arm 3 and a revolving door 11, and a driving turntable 5 for driving the rotating arm 3 to rotate.

The test table 2 is used as a reference surface in the test process, the kitchen appliance 1 to be tested is placed on the upper surface of the test table, and the rotating arm 3 is fixedly arranged. Because the rotary shafts of the rotary arms 3 and the kitchen electrical appliance 1 are arranged on the same plane and are parallel to each other, the rotary shaft of the rotary door 11 of the kitchen electrical appliance 1 and the rotary shaft of the rotary arm 3 can be arranged in a collinear manner by arranging the fixing block 6 for fixing and clamping the kitchen electrical appliance 1 on the test table board 2. Thus, by fixedly connecting the rotary arm 3 and the revolving door 11 by the connecting mechanism 4, the same rotation torque and angle of the rotary arm 3 and the revolving door 11 can be ensured.

In order to replace manual testing and improve the automation degree of the testing device, the utility model drives the rotating arm 3 to rotate by driving the turntable 5 so as to open or close the rotating door 11 of the kitchen appliance 1 to be tested. The driving turntable 5 can provide a rotation torque by the driving motor, so that the opening and closing angle of the revolving door 11 can be correspondingly controlled by controlling the starting and stopping time of the driving motor, and the opening or closing direction of the revolving door 11 can be correspondingly controlled by controlling the forward and reverse rotation directions of the driving motor. Considering that the rotating speed of the driving motor is often fast and the requirement of the rotating speed of the driving turntable 5 is difficult to meet, the utility model reduces the speed of the driving motor and then connects the driving motor to the driving turntable 5 by arranging the speed reducer capable of transmitting the rotating torque.

In a preferred embodiment, in order to protect the driving motor and the decelerator from the test environment, the revolving door test apparatus of the present invention is provided with a box 9 below the test table 2, and the driving motor and the decelerator are disposed inside the box 9 and are in driving connection with the driving turntable 5 through the top surface of the box 9. One side of box 9 is equipped with hinge door 91 that can open and shut, and the surface of hinge door 91 is equipped with handle 911 to make things convenient for operating personnel to install and overhaul driving motor and reduction gear after opening hinge door 91. The lower surface of the box body 9 is also provided with casters 10 to facilitate the transition transportation of the box body 9 and the test table 2 thereon.

As shown in fig. 1, the connecting mechanism 4 of the present invention includes a gripping jaw 41, a driving cylinder 42, and a longitudinal arm 43. The longitudinal arm 43 is disposed at one end of the rotating arm 3 away from the rotating shaft, the clamping jaw 41 is disposed on the longitudinal arm 43, and the clamping jaw 41 can be clamped on the handle 111 to realize the fixed connection between the rotating arm 3 and the rotating door 11. By providing the longitudinal arm 43, the position where the grip 111 is clamped by the clamping jaw 41 can be close to the middle of the handle 111, so that the force applied by the clamping jaw 41 to the handle 111 is more uniformly transmitted to the revolving door 11 of the electric cooking appliance 1 to be measured. In order to accurately control the force of the clamping claw 41 for clamping the handle 111, the clamping action and the releasing action of the clamping claw 41 are driven by the driving air cylinder 42.

In a preferred embodiment, the jaws 41 are height-adjustably positioned on the longitudinal arms 43 to adjust the location at which the jaws 41 grasp the handle 111. Thereby, it is possible to further detect the influence of the difference in the gripping position of the gripping jaw 41 on the handle 111 on the durability of the revolving door 11.

In order to facilitate the control of the revolving door testing device, the utility model further comprises a human-machine interface 7 arranged on the testing table top 2, and a start button 81, an emergency stop button 82 and a power indicator lamp 83 which are arranged below the human-machine interface 7 and adjacent to each other. The man-machine interface 7 can display and set the moment, angle and times of the rotation of the rotary arm 3 driven by the driving turntable 5, the start button 81 can start the driving turntable 5 and the driving cylinder 42, the emergency stop button 82 can pause the driving turntable 5 and the driving cylinder 42, and the power indicator 83 can indicate the starting or pausing states of the driving turntable 5 and the driving cylinder 42 through the self on-off change.

When the operator tests the revolving door 11 according to the present invention, the operator first energizes and ventilates the testing device to put the driving motor and the driving cylinder 42 in a standby state. The kitchen appliance 1 is then placed on the test table 2 at the position defined by the fixing block 6 and the revolving door 11 is rotated so that the handle 111 is located in the clamping jaw 41, completing the fixing of the kitchen appliance 1 to be tested. And then, the driving air cylinder 42 is started by operating a button on the man-machine interface 7, so that the clamping jaw 41 clamps the handle 111, and the preparation work before the test is finished.

In the testing process, an operator firstly starts the door closing button in the human-computer interface 7 to close the revolving door 11, and then releases the door closing button after the revolving door 11 is completely closed, so that the revolving door 11 is in the initial closed state. The operator then sets, via the human-machine interface 7, the angle of rotation of the revolving door 11 (which may be set, for example, to 90 °), the time of the test cycle (which may be set, for example, to 2.5 seconds, which includes the opening time, the dwell time and the closing time), and the number of test cycles (which may be set, for example, to 10000), so as to complete the parameter setting for the entire test procedure. Finally, the operator clicks the door opening button and observes whether the revolving door 11 rotates to a preset rotation angle, and after the rotation angle of the revolving door 11 meets the preset angle, the operator clicks the zero clearing button to zero the counted cycle number, and then clicks the start button 81 to start the automatic test operation of the revolving door 11.

Therefore, the utility model can automatically execute the action of opening and closing the revolving door 11 of the kitchen appliance 1 to be tested by arranging the rotating arm 3 and the driving turntable 5, so that the testing action and the qualified standard of the revolving door 11 are unified, the testing efficiency and the accuracy of the testing result are improved, and the time cost and the labor cost required by the testing of the revolving door 11 can be reduced.
