Description

Technical Field

[0001] This application relates to the field of steam oven testing devices, and in particular to a testing method for a testing device used to test the airtightness of a steam oven. Background Technology

[0002] Traditional methods for testing the airtightness of welded devices typically employ pneumatic pressure testing and helium mass spectrometry. Pneumatic pressure testing utilizes a differential pressure gauge to detect the pressure difference between the inside and outside of the test piece, thus determining if there is a leak. However, because the oven cavity is a non-sealed structure, primarily composed of sheet metal, pneumatic pressure testing is difficult to implement for non-sealed structures, and the pressure can easily cause structural deformation. Helium mass spectrometry involves filling the test piece with a helium-containing gas mixture and then using a mass spectrometer to detect the helium leakage rate, thus determining if there is a leak. However, helium mass spectrometry is also unsuitable for this structure. Firstly, strictly sealing any openings in the cavity before filling it with gas can also cause product deformation. Secondly, if the cavity is not properly sealed, helium can leak out from various openings, affecting the test results. Therefore, these testing methods require a high degree of container sealing and are not suitable for testing non-sealed cavities.

[0003] Therefore, the issue of airtightness testing of the steam oven cavity urgently needs to be addressed. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of this application is to avoid the excessive pressure generated inside the steam oven in the prior art, reduce the risk of structural deformation of the steam oven due to excessive pressure, and effectively evaluate the airtightness of the steam oven, ensuring the integrity of the steam oven structure and the ease of airtightness testing.

[0017] Preferably, the bracket includes a guide rail extending in a vertical direction, and the first sealing mechanism and the second sealing mechanism are connected by the guide rail.

[0018] Step S2 also includes the following steps:

[0020] Preferably, a sealing plate is provided on the movable end of the first sealing assembly, and the second sealing assembly includes a mounting plate connected to the sealing plate, with through holes through which the guide rail passes on the sealing plate and the mounting plate;

[0021] Step S23 also includes the following steps:

[0022] S231. Control the moving end of the first sealing component to drive the sealing plate to move along the setting direction of the guide rail, and at the same time drive the mounting plate to drive the second sealing component to move in the vertical direction, so that the second sealing component moves in the vertical direction to the same height as the venting part on the periphery of the steam oven.

[0023] Preferably, the second sealing assembly includes at least a bidirectional drive structure disposed on one side of the steam oven. The bidirectional drive structure includes a first drive member that drives in the vertical direction and a second drive member that drives in the horizontal direction. The drive end of the first drive member is disposed on the sealing plate. The moving end of the first drive member is connected to the drive end of the second drive member. The drive source of the first drive member is the same as the drive source of the second sealing assembly on the remaining periphery of the steam oven.

[0024] Step S231 above also includes the following steps:

[0025] S2311. Control the second sealing member of the steam oven on the remaining periphery to move horizontally to seal the vent, while controlling the first driving member to move vertically to a preset position.

[0052] like Figures 1-9 As shown in the figure, this embodiment discloses a detection method for a detection device for detecting the airtightness of a steam oven. The detection device 100 is used to detect the airtightness of the gap between the vertical drum and the rear cover of the steam oven.

[0053] The detection device 100 includes a support 11, a water storage tank 12 and a sealing mechanism 13 disposed on the support 11. The sealing mechanism 13 is disposed vertically above the water storage tank 12. The temperature of the liquid in the water storage tank is controlled below 80°C. Otherwise, if the liquid boils, the water storage tank will be full of bubbles, and it will be impossible to observe whether there is a leak in the gap. Furthermore, a accommodating space 111 for accommodating the steam oven is provided between the sealing mechanism 13 and the water storage tank 12. At the same time, a venting part 13111 is provided on the sealing mechanism 13 to introduce gas in the range of 95-110°C into the vertical barrel through the venting part. The temperature is controlled within this range to simulate the actual use scenario of the steam oven. If the gap between the vertical barrel and the rear cover of the steam oven meets the airtightness requirements when tested at room temperature, it does not mean that the airtightness of the gap will meet the requirements when the steam oven is actually used. In actual use, the temperature inside the vertical barrel of the steam oven is generally around 95-100°C. Therefore, when the steam oven is tested after introducing high-temperature gas of 95-110°C, if the gap meets the airtightness requirements, then the steam oven will also meet the requirements when used in the actual high-temperature environment. There will be no problem of the steam oven leaking air due to the high-temperature environment, which could lead to safety hazards.

[0054] The detection method of the detection device for detecting the airtightness of a steam oven includes the following steps:

[0055] S1. Place the steam oven into the accommodating space 111, and put the gap between the upright bucket 21 and the rear cover 22 into the water storage tank 12;

[0056] S2. Control the sealing mechanism 13 to move toward one side of the steam oven to immerse the gap below the liquid surface of the water tank 12, while sealing the vent of the steam oven.

[0057] S3. The ventilation section 13111 and the vent section are connected to each other so that the ventilation section 13111 can be used to fill the cavity of the steam oven with air, and it is determined whether air bubbles are generated in the water tank 12 to detect the airtightness of the gap.

[0058] Specifically, in step S2, the sealing mechanism 13 is controlled to move vertically toward one side of the steam oven 200, so that the sealing mechanism 13 acts on the side of the steam oven 200 away from the gap, so as to immerse the gap below the liquid surface of the water tank 12, while sealing the vent 23 on the steam oven 200.

[0059] In this embodiment, the above-mentioned detection method allows for a direct observation of the airtightness of the gaps by observing the presence or absence of air bubbles in the water. Furthermore, the detection device 100 is applicable to steam ovens of various shapes and sizes, and avoids the excessive pressure that may occur inside the steam oven in the prior art, thus reducing the risk of structural deformation due to excessive pressure. This visual detection method can effectively assess the airtightness of the steam oven, ensuring the integrity of the steam oven structure and the ease of airtightness detection.

[0060] like Figure 5 As shown, a base plate 121 supporting the steam oven is also provided at the bottom of the water storage tank 12. This ensures the stability of the steam oven during the testing process and prevents errors in the test results due to instability or positional shift. Furthermore, a clearance groove 122 is provided on the base plate 121 to allow the rear cover to avoid the base plate 121 when placing the steam oven, preventing damage and ensuring the integrity of the gaps submerged in the water storage tank 12. This guarantees the accuracy of the airtightness test results. Therefore, in this embodiment, the part in direct contact with the steam oven is made of soft material. Simultaneously, a positioning member 123 is provided around the clearance groove 122 to limit the position of the steam oven, ensuring that the steam oven does not move horizontally and maintaining a fixed relative position between the steam oven and the sealing mechanism 13. This ensures consistent testing and reduces test errors caused by changes in the position of the steam oven.

[0061] Therefore, step S1 also includes the following step: when the gap is placed into the water storage tank 12, the back cover and the positioning member 123 are matched.

[0062] In step S11, when the gap is placed into the water tank 12, the gap and the positioning member 123 are matched to ensure that when the steam oven is placed, the positioning edge 221 of the rear cover 22 can accurately match the positioning member 123, so that the steam oven is kept in the correct position, avoiding misjudgment of gap leakage detection due to the position of the steam oven being offset, and improving the reliability of sealing detection.

[0063] In this embodiment, the positioning element 123 is a positioning block, which surrounds the periphery of the clearance groove 122, and the outer side of the positioning edge 221 of the rear cover 22 is fitted with the inner side of the positioning block to achieve the positioning effect of the steam oven. In other embodiments, the selection and position of the positioning element 123 can be set as needed according to the structural form of the steam oven, as long as it can meet the requirements of positioning and airtightness testing of the steam oven.

[0064] like Figures 2-3 As shown, the sealing mechanism 13 also includes a first sealing component 131 and a second sealing component 132, which are used to seal the vent of the steam oven in the vertical and circumferential directions, respectively. This arrangement can ensure that the steam oven is completely sealed during the testing process, preventing gas from leaking from any direction, thereby improving the accuracy and reliability of the test.

[0065] Therefore, step S2 also includes the following steps:

[0066] S21. Control the first sealing assembly 131 to move vertically toward one side of the steam oven to immerse the gap below the liquid surface of the water tank 12, while sealing the air vent of the steam oven in the vertical direction.

[0067] S22. Control the second sealing assembly 132 to move horizontally toward one side of the steam oven to seal the venting portion of the steam oven in the circumferential direction.

[0068] Therefore, in step S21, the gap is submerged below the liquid surface, and the vent in the vertical direction of the steam oven is sealed. This ensures that the gap of the steam oven is completely surrounded by the liquid in the water tank 12, creating conditions for subsequent airtightness testing.

[0069] In step S22, the second sealing assembly 132 is controlled to move horizontally to seal the vent in the circumferential direction of the steam oven, thus ensuring that the sides of the steam oven are also completely sealed to prevent gas from leaking from the sides.

[0070] By employing the above steps, the sealing mechanism 13 can comprehensively seal the venting portion of the steam oven 200 from both the vertical and circumferential directions, ensuring that leakage will not affect the test results during the testing process, thus improving the accuracy and reliability of the test. Furthermore, this sealing method can adapt to steam ovens of different shapes and sizes, improving the applicability and flexibility of the testing device.

[0071] In other embodiments, step S22 can be used first and then step S21, that is, the vent in the horizontal direction of the steam oven can be sealed first, and then the vent in the vertical direction of the steam oven can be sealed. As long as the sealing requirements of the steam oven can be met, the specific order is not limited.

[0072] like Figures 2-3 As shown, a guide rail 112 extending vertically is also provided on the bracket 11, which is used to drive the connection between the first sealing component 131 and the second sealing component 132. This allows the two sealing components to move synchronously, ensuring that the vent of the steam oven is sealed in both the vertical and circumferential directions.

[0073] Therefore, step S2 also includes the following steps:

[0074] S23. While controlling the first sealing component 131 to move vertically toward the side of the steam oven, the second sealing component 132 is also moved vertically.

[0075] Therefore, in step S23, through the transmission connection of the guide rail 112, when the first sealing component 131 moves in the vertical direction to seal the vertical vent of the steam oven, the second sealing component 132 will also be synchronously driven to move in the vertical direction. This setting not only ensures that the actions of the two sealing components are consistent, simplifying the operation process and the complexity of the control system, thereby reducing potential sources of error, but also ensures that the synchronous movement of the first sealing component 131 and the second sealing component 132 can ensure that the vent of the steam oven is sealed in multiple directions at the same time, improving the sealing efficiency.

[0076] like Figures 2-3As shown, a sealing plate 1311 is also provided on the moving end of the first sealing assembly 131. In this embodiment, the sealing plate 1311 and the first sealing assembly 131 are connected by bolts. The second sealing assembly 132 also includes a mounting plate 1321 connected to the sealing plate 1311. The guide rail 112 passes through the through holes on the sealing plate 1311 and the mounting plate 1321. This arrangement allows the moving end of the first sealing assembly 131 to drive the sealing plate 1311 to move along the guide rail 112, and the mounting plate 1321 to drive the second sealing assembly 132 to move synchronously in the vertical direction. At the same time, in this embodiment, the venting part 13111 is provided on the sealing plate 1311 in the form of a vent hole to enable ventilation of the oven cavity.

[0077] Therefore, step S23 also includes the following steps:

[0078] S231, control the moving end of the first sealing component 131 to drive the sealing plate 1311 to move along the setting direction of the guide rail 112, and at the same time drive the mounting plate 1321 to drive the second sealing component 132 to move in the vertical direction, so that the second sealing component 132 moves in the vertical direction to the same height as the air vent on the periphery of the steam oven.

[0079] Therefore, in step S231, through the transmission connection of the guide rail 112, the movement of the first sealing component 131 and the second sealing component 132 can be precisely synchronized, simplifying the design of the control system and making the movement of the sealing mechanism 13 simpler. Furthermore, the second sealing component 132 moving to the same height as the venting portion around the steam oven ensures that the sealing plate 1311 and the mounting plate 1321 can accurately correspond to the sealing position of the steam oven, reducing the risk of seal failure due to inaccurate positioning.

[0080] In addition, such as Figures 2-3 As shown, a reinforcing plate 1312 is provided between the driving end and the moving end of the first sealing assembly 131. In the vertical direction, the projected area of ​​the reinforcing plate 1312 is larger than the projected area of ​​the sealing plate 1311. The central axes of the reinforcing plate 1312 and the sealing plate 1311 are the same as the central axis of the first sealing assembly 131. The guide rails 112 are respectively provided at the ends of the reinforcing plate 1312 and the sealing plate 1311.

[0081] Furthermore, a reinforcing rib 13121 is provided on the side surface of the reinforcing plate 1312 facing the driving end of the first sealing assembly 131 to enhance the ability of the reinforcing plate 1312 to withstand the driving of the first sealing assembly 131.

[0082] like Figure 4As shown, the second sealing assembly 132 also includes at least one bidirectional drive structure 1322 disposed on one side of the steam oven. The bidirectional drive structure 1322 includes a first drive member 13221 that drives vertically and a second drive member 13222 that drives horizontally. The drive end of the first drive member 13221 is disposed on the sealing plate 1311, and the moving end of the first drive member 13221 is connected to the drive end of the second drive member 13222. The drive source of the first drive member 13221 is the same as the drive source of the second sealing assembly 132 on the remaining periphery of the steam oven. This bidirectional drive structure 1322 can drive in both the vertical and horizontal directions. This arrangement facilitates the placement of the steam oven into the receiving space 111 and facilitates operation by the staff.

[0083] Therefore, step S231 also includes the following steps:

[0084] S2311, Control the second seal of the steam oven on the remaining periphery to move horizontally to seal the vent, and at the same time control the first drive 13221 to move vertically to a preset position;

[0085] S2312, Control the second drive member 13222 to move horizontally toward the side of the steam oven vent, so as to seal the vent on the surface of the steam oven facing the second drive member 13222.

[0086] Therefore, in step S2311, the second sealing component on the remaining periphery of the steam oven is controlled to move horizontally and the first driving component 13221 is controlled to move vertically, so that the second sealing component 132 on the remaining periphery of the steam oven can seal the vent in the horizontal direction. At the same time, the first driving component 13221 moves to the preset position in the vertical direction to ensure that it moves to the same height as the vent in the horizontal direction first, in preparation for subsequent sealing.

[0087] In step S2312, after the first drive member 13221 reaches the preset height, the second drive member 13222 is controlled to move horizontally to seal the vent on the surface of the steam oven facing the second drive member 13222.

[0088] Therefore, after placing the steam oven into the accommodating space 111, the above steps are then performed. By using the linkage drive of the first drive component 13221 and the second drive component 13222, a precise sealing position can be achieved, improving the accuracy of the seal.

[0089] In this embodiment, a bidirectional drive structure 1322 is provided only on one side of the steam oven along its length to facilitate its placement. The bidirectional drive structure 1322 consists of a vertically extending cylinder and a horizontally extending thumb cylinder. Three bidirectional drive structures 1322 are arranged alternately along the length of the steam oven. In other embodiments, the bidirectional drive structure 1322 can be configured along the length or width of the steam oven as needed, and the appropriate drive type and connection method can be selected to meet the requirements for placement and airtightness testing of the steam oven.

[0090] like Figure 3 As shown, the bracket 11 is also provided with a support platform 113 at the same height as the receiving space 111 and located around the receiving space 111. The second sealing assembly 132 also includes a drive structure 1323 provided on the support platform 113 and a sealing plug 1324 provided at the vent of the steam oven. This arrangement allows the drive structure 1323 to move horizontally to push the sealing plug 1324 to contact the vent of the steam oven and achieve a seal.

[0091] Therefore, step S22 also includes the following steps:

[0092] S221. Control the drive structure 1323 to move horizontally toward one side of the steam oven, so that the moving end of the drive structure 1323 contacts the sealing plug 1324 and limits the sealing plug 1324 on the vent.

[0093] Therefore, in step S221, the drive structure 1323 moves in the horizontal direction, and its moving end contacts the sealing plug 1324, pushing the sealing plug 1324 into the vent of the steam oven, thereby achieving a seal and ensuring that the vent of the steam oven in the circumferential direction can be effectively sealed.

[0094] like Figure 5 As shown, the support 11 also includes a support plate 114 disposed inside the water storage tank 12 and used to support the steam oven. The support plate 114 has an extension section 1141 in the horizontal direction facing away from the water storage tank 12. The detection device 100 also includes an ejection mechanism 14 disposed at the bottom end of the extension section 1141 in the vertical direction. In this embodiment, the ejection mechanism 14 is disposed at both ends of the steam oven along its length.

[0095] Therefore, before step S21, the following steps are also included:

[0096] S20. Turn off the drive source of the ejector mechanism 14 to stop the operation of the ejector mechanism 14.

[0097] Therefore, in step S20, before the detection process begins, the drive source of the ejector mechanism 14 is turned off, the operation of the ejector mechanism 14 is stopped, and after the ejector mechanism 14 is turned off, the steam oven is no longer subjected to an upward ejection force, so that the gap of the steam oven can be immersed into the water storage tank 12, and prepare for the first sealing component 131 to seal the steam oven in the vertical direction and press the steam oven into the water storage tank 12.

[0098] Preferably, in this embodiment, the drive source of the ejector mechanism 14 and the drive source of the first sealing component 131 are the same. Since both the first sealing component 131 and the ejector mechanism 14 in this application are driven by cylinders, the first sealing component 131 and the ejector mechanism 14 share the same air inlet pipe and exhaust pipe. Therefore, this arrangement allows the ejector mechanism 14 to be stopped and the first sealing component 131 to be moved by controlling a single drive source, thereby simplifying the control process and improving the operating efficiency.

[0099] Therefore, step S21 also includes the following steps:

[0100] S211. While shutting off the drive source of the ejector mechanism 14, the drive source controls the first sealing assembly 131 to move vertically toward one side of the steam oven, immersing the gap below the liquid surface of the water tank 12, and sealing the air vent of the steam oven in the vertical direction.

[0101] Therefore, in step S211, while the drive source of the ejector mechanism 14 is turned off, the drive source controls the first sealing assembly 131 to move vertically toward one side of the steam oven, which can submerge the gap below the liquid surface of the water tank 12 and seal the venting part of the steam oven in the vertical direction.

[0102] In addition to step S4, the following steps are also included:

[0103] S5. Control the sealing mechanism 13 to reset, and at the same time control the ejection mechanism 14 to drive the bearing plate 114 to move upward in the vertical direction, so as to drive the steam oven to detach from the liquid surface of the water tank 12.

[0104] S6. Remove the steam oven from the storage space 111.

[0105] Therefore, in step S5, after the airtightness test is completed, the sealing mechanism 13 is first reset to release the sealing state of the steam oven, and the ejection mechanism 14 is controlled to drive the support plate 114 to move upward in the vertical direction. The purpose of doing this is to lift the steam oven out of the liquid surface of the water tank 12 and make it detach from the liquid surface.

[0106] In step S6, the staff can easily remove the steam oven from the housing space 111 for further processing or transfer it to another location.

[0107] Therefore, by controlling the ejection mechanism 14, the staff can easily lift the steam oven from the water tank 12, reducing the labor intensity of the staff, improving the efficiency of removal, and making the whole testing process more user-friendly.

[0108] In this embodiment, both the sealing mechanism 13 and the ejection mechanism 14 are cylinder-driven to seal the venting part of the steam oven. In other embodiments, other existing technologies can be selected as needed, such as motor drive, and the ejection mechanism 14 can also be a spring or other material that meets the requirements of ejecting the steam oven.

[0109] In summary, in this embodiment, the specific testing method for the airtightness of the steam oven 200 includes the following steps:

[0110] Step 1: Place the steam oven 200 into the receiving space 111 from one side of the bidirectional drive structure 1322, so that the gap between the upright 21 and the rear cover 22 is placed into the water tank 12. At the same time, make the positioning edge 221 on the rear cover 22 fit into the positioning block in the water tank 12 to achieve positioning of the steam oven 200.

[0111] Step 2: Turn off the drive source of the ejector mechanism 14, control the ejector mechanisms 14 on the left and right sides to retract, and at the same time, control the first sealing component 131 to move vertically toward one side of the steam oven 200, immersing the gap below the liquid surface of the water tank 12, and sealing the air vent 23, i.e. the through hole, in the vertical direction of the steam oven 200. At the same time, the movement of the first sealing component 131 in the vertical direction can drive the second sealing component 132 to move in the vertical direction.

[0112] Step 3: Control the second sealing components 132 on the left and right sides of the control bracket 11 and the support platform 113 to move horizontally toward one side of the steam oven 200, so that the second sealing components 132 on the left and right sides can seal the vents 23 on the left and right sides of the steam oven 200, and so that the drive structure 1323 drives the sealing plug 1324 to seal the vent 23 on the side where the electromagnetic coil of the steam oven 200 is located. At the same time, control the first drive member 13221 to move vertically to a preset position;

[0113] Step 4: Control the second drive unit 13222 to move horizontally toward one side of the steam oven 200 vent 23 to seal the front oven light hole and heating tube bracket 11 hole in the side of the steam oven 200.

[0114] Step 5: Ventilate the cavity of the steam oven 200 through the vent 13111 on the sealing plate 1311, and check whether air bubbles are generated in the water tank 12 to test the airtightness of the gaps.

[0115] Step 6: Control the sealing mechanism 13 to reset, and at the same time control the ejection mechanism 14 to drive the support plate 114 to move upward in the vertical direction, so as to drive the steam oven 200 to detach from the liquid surface of the water tank 12.

[0116] Step 7: Remove the steam oven 200 from the storage compartment 111.

[0117] In other embodiments, the steam oven is not limited to the steam oven 200 described above, but can also be a steam box. The gap is not limited to the gap between the vertical barrel 21 and the rear cover 22 described above. At the same time, the location of the sealing mechanism 13 and the ejection mechanism 14 is not limited in this application. The detection device 100 can be adjusted according to the specific structure of the steam oven and the location of the vent 23 on the steam oven.

[0118] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
