Description

Technical Field

[0001] The invention relates to the technical field of manufacturing electric ceramic stove accessories, and specifically proposes a performance detection device for electric ceramic stove accessories. Background Art

[0002] An electric ceramic stove is a stove device that uses the thermal effect of electric current to convert electrical energy into thermal energy. Its main structure is composed of a heating plate, a microcrystalline glass plate, an electronic control system and a stove body. Among them, the microcrystalline glass plate has excellent thermal conductivity, high temperature resistance, impact resistance, chemical stability and thermal stability, so it is widely used in household appliances such as electric ceramic stoves. The microcrystalline glass plate not only supports and protects the internal heating elements, but also directly affects the heating efficiency, safety and service life of the electric ceramic stove.

[0003] Microcrystalline glass panels will experience frequent temperature changes during use, such as rapid heating from room temperature to high temperature in a short period of time, or contact with cold water immediately after cooking. In other words, the microcrystalline glass panels will be subjected to sudden temperature changes, which may cause stress inside the microcrystalline glass panels, thus affecting their integrity and safety. Therefore, manufacturers usually conduct strict thermal stability tests on microcrystalline glass panels to ensure that the products can work safely and reliably and have a long service life.

[0004] Currently, when conducting thermal stability tests on microcrystalline glass plates, a single sudden heating and sudden cooling temperature conversion method is adopted to test the microcrystalline glass plates. In actual use, when the temperature of the microcrystalline glass plates rises, they will also be affected by the weight of cooking utensils and food. These weights have a great impact on the test of the microcrystalline glass plates during the heating process, thereby reducing the comprehensiveness and accuracy of the thermal stability test of the microcrystalline glass plates. In addition, during the sudden cooling and heating tests of the microcrystalline glass plates, multiple drives are required to cooperate to convert the microcrystalline glass plates between the sudden cooling zone and the sudden heating zone, and to seal the two test areas. There may be communication delays or synchronization problems between the multiple drive units, which affects the accuracy of the control and then affects the accuracy of the detection.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] See also Figure 1 and Figure 2 A performance testing device for electric ceramic stove accessories includes: a testing box 1, the testing box 1 is divided into a chamber 10 and a chamber 2 11 by a partition 12, a heating system and a cooling system are installed in the chamber 10 and the chamber 2 11 respectively, and the testing box 1 is provided with a sealing door panel 13 located on the top of the chamber 2 11 and used for opening and closing.

[0035] The heating system and the cooling system are both existing equipment, and the heating system and the cooling system respectively heat the chamber 1 10 at high temperature and cool the chamber 2 11 at low temperature.

[0036] See also Figure 2 A connecting passage 14 is provided in the middle of the partition 12 to connect the chamber 10 with the chamber 2 11. The chambers 10, 11 and the connecting passage 14 are provided with tracks 2 symmetrically arranged along the width direction of the test box 1. The tracks 2 are connected with a supporting seat 3 that slides along the length direction thereof.

[0037] See also Figure 2A load-bearing simulation group 4 is installed in the chamber 10 so as to slide up and down, an opening and closing mechanism 5 is installed on the connecting channel 14 so as to slide up and down, and a clamping mechanism 6 for fixing the microcrystalline glass plate 8 is detachably connected between the two supporting seats 3; a unified driving mechanism 7 is installed on the two supporting seats 3.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The opening and closing mechanism 5 includes a receiving groove 50 opened at the top of the connecting channel 14, and a gate plate 51 that slides up and down is connected between the receiving groove 50 and the connecting channel 14. The bottom of the gate plate 51 is provided with a card slot arranged along its length direction and engaged with the track 2. The gate plate 51 is also provided with a top opening matching group 52 that cooperates with the unified driving mechanism 7 to drive the gate plate 51 to move upward.

[0039] An electric slider is installed on the supporting seat 3 to drive it to slide back and forth intermittently along the length direction of the track 2. During inspection, the microcrystalline glass plate 8 is fixed by the clamping mechanism 6, and the sealing door panel 13 on the top of the chamber 2 11 is opened, the clamping mechanism 6 is fixed between the two supporting seats 3, and then the top of the chamber 2 11 is sealed by the sealing door panel 13.

[0040] Afterwards, the microcrystalline glass plate 8 is driven by the supporting seat 3 and the clamping mechanism 6 to intermittently transfer between the chamber 10 and the chamber 2 11, so as to perform a thermal stability test of the microcrystalline glass plate 8 by sudden heating and cooling: when the supporting seat 3 drives the microcrystalline glass plate 8 to quickly transfer from the chamber 2 11 to the chamber 1 10, the unified driving mechanism 7 first cooperates with the top opening matching group 52 to push the gate plate 51 to move upward to open the connecting channel 14, and then the clamping mechanism 6 drives the microcrystalline glass plate 8 to pass through the connecting channel 14 and enter the chamber 1 10. When the microcrystalline glass plate 8 enters the chamber 10, the unified driving mechanism 7 first drives the load simulation group 52 to push the gate plate 51 upward to open the connecting channel 14. 4 moves upward so that the microcrystalline glass plate 8 moves to the bottom of the weight simulation group 4. When the microcrystalline glass plate 8 moves to the bottom of the weight simulation group 4, the weight simulation group 4 presses on the microcrystalline glass plate 8 under the action of its own gravity, simulating the weight that the microcrystalline glass plate 8 is actually subjected to, combining the heating of the microcrystalline glass plate 8 with the weight, thereby improving the authenticity, comprehensiveness and accuracy of the thermal stability performance test of the microcrystalline glass plate 8. At the same time, the gate plate 51 closes the connecting channel 14 to prevent the hot air flow and the cold air flow in the chamber 1 10 and the chamber 2 11 from communicating with each other, causing energy loss and unstable test temperature.

[0041] In addition, during the movement of the supporting seat 3, the unified driving mechanism 7 cooperates with the load-bearing simulation group 4 and the top-opening matching group 52, thereby realizing the integrated driving of the supporting seat 3, the load-bearing simulation group 4 and the gate plate 51 for lifting and lowering, greatly improving the accuracy of the movement and coordination between the load-bearing simulation group 4, the gate plate 51 and the supporting seat 3, and also improving the convenience of driving.

[0042] It is particularly noted that the electric slider drives the support seat 3 to move so that the unified driving mechanism 7 drives the gate plate 51 to move up to open the connecting channel 14 at a faster speed, and the gate plate 51 moves down to close the connecting channel 14 at a faster speed. During this process, the cross-flow generated by the airflow between chamber 10 and chamber 2 11 can be ignored.

[0043] See also Figure 2 and Figure 6 The lower end surface of the connecting channel 14 is provided with an interpolation groove 140 arranged in an alternating manner with the track 2, and a sealing gasket 142 is installed in the interpolation groove 140. The bottom of the gate plate 51 is provided with a supplementary insert 141 corresponding to the interpolation groove 140. The interpolation groove 140, the supplementary insert 141, and the sealing gasket 142 cooperate to increase the plug-in sealing contact surface between the bottom of the gate plate 51 and the connecting channel 14, thereby improving the sealing between the gate plate 51 and the connecting channel 14, avoiding the airflow in the chamber 10 and the chamber 2 11 from communicating with each other, thereby affecting the accuracy of the performance detection of the microcrystalline glass plate 8.

[0044] See also Figure 2 , Figure 3 and Figure 5 The fixing mechanism 6 includes two supporting half rings 60, the vertical cross-section of the supporting half rings 60 is L-shaped, the opposite ends of the two supporting half rings 60 are slidably plugged in and locked by a locking group 61, and the opposite side walls of the two supporting half rings 60 are installed with T-shaped card plates 62, and the supporting seat 3 is provided with a T-shaped card groove that matches the T-shaped card plate 62, and the supporting seat 3 is installed with a locking assembly 63 for limiting the upward and downward sliding of the T-shaped card plate 62.

[0045] See also Figure 2 , Figure 3 and Figure 5 The locking group 61 includes an L-shaped plate 610 on which both end side walls of one supporting half ring 60 are slidably inserted, and both end side walls of the other supporting half ring 60 are provided with inclined surfaces. The L-shaped plate 610 is connected to a screw rod 611 by threaded cooperation, and the screw rod 611 is rotatably connected to the corresponding end of the supporting half ring 60. The end of the L-shaped plate 610 away from the screw rod 611 is set as an inclined surface and is rollingly connected with a ball (not shown in the figure), and the ball rolls in contact with the inclined surface on the supporting half ring 60.

[0046] When the microcrystalline glass plate 8 is initially placed, the fixing mechanism 6 is not placed on the two supporting seats 3 for the convenience of fixing the microcrystalline glass plate 8. Then the microcrystalline glass plate 8 is placed on the horizontal sections of the two supporting half rings 60 and the two supporting half rings 60 are pushed closed. Then the screw 611 is rotated, and the screw 611 drives the L-shaped abutment plate 610 to move radially along the microcrystalline glass plate 8 until the ball on the L-shaped abutment plate 610 is tightly pressed against the inclined surface, thereby limiting and locking the two supporting half rings 60 to avoid the problem that the microcrystalline glass plate 8 shakes and cracks when the microcrystalline glass plate 8 is subjected to a thermal stability test of sudden heating and cooling, thereby affecting the judgment of the test results.

[0047] Then, the T-shaped clamps 62 on the two supporting half rings 60 are placed in the corresponding T-shaped slots from above the chamber 2 11, and the two T-shaped clamps 62 are fixed by the latch assembly 63, which also locks the two closed and locked supporting half rings 60 as a whole, ensuring that the microcrystalline glass plate 8 is stably fixed.

[0048] See also Figure 3 and Figure 5 The vertical section and the horizontal section of the supporting half ring 60 are both hollow structures, so that the microcrystalline glass plate 8 can be quickly heated or cooled, and the performance test can be accurately performed.

[0049] See also Figure 3 and Figure 7 The latch assembly 63 includes an L-shaped groove 630 opened on the supporting seat 3 and connected to the T-shaped slot, an L-shaped plug block 631 is slidably connected in the L-shaped groove 630, and a plug-in groove for plugging and cooperating with the L-shaped plug block 631 is opened on the side wall of the T-shaped card plate 62. When the T-shaped card plate 62 is placed in the T-shaped slot, the horizontal section of the L-shaped plug block 631 is pushed into the plug-in groove, and the L-shaped plug block 631 is tightly plugged in the plug-in groove, thereby limiting and locking the up and down movement of the T-shaped card plate 62.

[0050] See also Figure 2 and Figure 3 The unified driving mechanism 7 includes an opening and closing pushing assembly 70 and a lifting and lifting pushing assembly 71 installed on the supporting seat 3. The opening and closing pushing assembly 70 is a trapezoidal plate installed on the supporting seat 3. Both sides of the trapezoidal plate arranged along its length direction are inclined surfaces. The trapezoidal plate is aligned with the track 2 up and down, and the distance between the two inclined surfaces of the trapezoidal plate is greater than the outer diameter of the supporting semi-ring 60.

[0051] See also Figure 2 , Figure 3 , Figure 4 and Figure 6The top-opening matching group 52 includes slide grooves 520 provided on both sides of the partition 12 arranged along its width direction, and the slide grooves 520 are symmetrically arranged along the length direction of the partition 12. The slide grooves 520 are connected with the storage groove 50, and the two side walls of the gate plate 51 arranged along its width direction are installed with extension supplement seats 521 corresponding to the slide grooves 520 one by one. A lifting rod 522 is installed at the bottom of the extension supplement seat 521. The lifting rod 522 is located directly above the track 2, and a ball is rollingly connected to the bottom of the lifting rod 522. A push spring 523 is installed between the top of the gate plate 51 and the storage groove 50.

[0052] When the support seat 3 moves, it drives the trapezoidal plate to move synchronously, and the inclined surface of the trapezoidal plate close to the lifting rod 522 pushes the lifting rod 522 to move upward, and the gate plate 51 moves upward under the cooperation of the two trapezoidal plates and the two corresponding lifting rods 522, thereby opening the connecting channel 14, and then the support seat 3 continues to drive the microcrystalline glass plate 8 to move, and the lifting rod 522 moves along the top horizontal section of the trapezoidal plate until the microcrystalline glass plate 8 enters chamber 2 11 from chamber 10 or enters chamber 10 from chamber 2 11, and then the lifting rod 522 moves downward along the inclined surface on the other side of the trapezoidal plate. The gate plate 51 moves downward under the action of its own gravity and the elastic force of the push spring 523 until the gate plate 51 is tightly pressed against the lower end surface of the connecting channel 14, and the supplementary insert 141 drives the sealing gasket 142 to be inserted into the corresponding interpolation groove 140 to seal the connecting channel 14. Through the above process, the integrated operation of the transfer of the microcrystalline glass plate 8 between chamber two 11 and chamber one 10 and the opening and closing of the gate plate 51 is realized, which is beneficial to improve the convenience of the detection of the microcrystalline glass plate 8, and at the same time avoid the airflow in chamber two 11 and chamber one 10 from being connected, which affects the accuracy of the performance detection of the microcrystalline glass plate 8.

[0053] See also Figure 2 The load-bearing simulation group 4 includes a weight plate 40 connected to the chamber 10 by sliding up and down through a connecting plate. The side wall of the weight plate 40 is equipped with two ear plates symmetrically arranged along the width direction of the detection test box 1. A support rod 41 is fixedly installed at the lower end of the ear plate, and a ball is rollingly connected to the bottom of the support rod 41.

[0054] See also Figure 2 , Figure 3 , Figure 4 and Figure 6The lifting and pushing assembly 71 includes a guide plate 710 installed on the supporting seat 3, and the two guide plates 710 are located between the two opening and closing pushing assemblies 70. One end of the guide plate 710 is located on the supporting seat 3, and the other end of the guide plate 710 is in a suspended state. A supporting member 711 for supporting the suspended end of the guide plate 710 is installed on the side of the chamber 10 away from the partition 12. The side wall of the suspended end of the guide plate 710 is an inclined surface, and a V-shaped groove 712 is provided on the top of the other end of the guide plate 710 and is arranged to penetrate along its width direction. The guide plate 710 and the corresponding push rod 41 are located in the same vertical plane, and the distance between the inclined surface of the guide plate 710 and the V-shaped groove 712 is greater than the radius of the supporting semi-ring 60.

[0055] When the glass-ceramic plate 8 enters the chamber 10 from the chamber 2 11, the inclined surface of the guide plate 710 rolls with the ball at the lower end of the push rod 41, and as the guide plate 710 moves, its inclined surface pushes the push rod 41 to drive the weight plate 40 to move upward, so that the glass-ceramic plate 8 moves to the bottom of the weight plate 40. When the glass-ceramic plate 8 moves below the weight plate 40, the ball at the lower end of the push rod 41 rolls on the horizontal surface of the top of the guide plate 710; when the push rod 41 enters the V-shaped groove 712 When the weight plate 40 is raised, it gradually moves downward under the action of its own gravity. When the ball at the lower end of the support rod 41 collides with the inner angle of the V-shaped groove 712, the weight plate 40 is completely pressed on the top of the microcrystalline glass plate 8, thereby simulating the weight that the microcrystalline glass plate 8 is actually subjected to, combining the heating and load-bearing of the microcrystalline glass plate 8, and thereby improving the authenticity and accuracy of the thermal stability performance test of the microcrystalline glass plate 8. At this time, the V-shaped groove 712 also limits the support rod 41, so that the load-bearing of the microcrystalline glass plate 8 is stable.

[0056] When the microcrystalline glass plate 8 moves from chamber 10 to chamber 2 11 , the support seat 3 drives the guide plate 710 to move so that the inclined surface of the V-shaped groove 712 cooperates with the support rod 41 to push the weight plate 40 upward and separate from the microcrystalline glass plate 8 .

[0057] See also Figure 1-Figure 7 During the specific inspection, the microcrystalline glass plate 8 is first fixed by the fixing mechanism 6, and the sealing door plate 13 on the top of the chamber 2 11 is opened, and then the fixing mechanism 6 is fixed between the two supporting seats 3, and then the top of the chamber 2 11 is sealed by the sealing door plate 13.

[0058] Afterwards, the support seat 3 and the fixing mechanism 6 drive the glass-ceramic plate 8 to perform intermittent rotation transfer between the chamber 1 10 and the chamber 2 11, so as to perform a thermal stability performance test of the glass-ceramic plate 8 by sudden heating and cooling: when the support seat 3 drives the glass-ceramic plate 8 to quickly transfer from the chamber 2 11 to the chamber 1 10, the unified driving mechanism 7 first cooperates with the top opening matching group 52 to push the gate plate 51 to move upward to open the connecting channel 14, and then the fixing mechanism 6 drives the glass-ceramic plate 8 to pass through the connecting channel 14 to enter. When the microcrystalline glass plate 8 enters the chamber 10, the unified driving mechanism 7 first drives the weight simulation group 4 to move upward, so that the microcrystalline glass plate 8 moves to the bottom of the weight simulation group 4. When the microcrystalline glass plate 8 moves to the bottom of the weight simulation group 4, the weight simulation group 4 presses on the microcrystalline glass plate 8 under the action of its own gravity, simulating the weight that the microcrystalline glass plate 8 is actually subjected to, and combining the heating of the microcrystalline glass plate 8 with the weight. At the same time, the gate plate 51 closes the connecting channel 14.
