Description

Technical Field

[0001] This invention relates to the field of oven technology, and more particularly to an oven control panel. Background Technology

[0002] An oven is a sealed appliance used for baking food or drying products. The oven control panel includes the housing and a PCBA board on the back of the housing. Pressing a button on the housing triggers a signal from the PCBA board via a touch spring and a sensor plate, adjusting the oven's operating status. However, existing oven control panels are inconvenient to disassemble and install, making quick disassembly for repairs difficult when the PCBA board or housing malfunctions. Therefore, designing an oven control panel that is easy to disassemble and improves maintenance efficiency has become an urgent technical problem to solve. Summary of the Invention

[0003] To solve the above problems, this utility model provides an oven control panel.

[0004] The present invention provides an oven control panel, comprising a transparent cover, an outer shell, and a circuit board. The back of the transparent cover has a receiving cavity and a first surrounding plate forming the side wall of the receiving cavity. The outer shell is disposed within the receiving cavity. The back of the outer shell has an installation cavity and a second surrounding plate forming the side wall of the installation cavity. The circuit board is disposed within the installation cavity. The inner side of the second surrounding plate has a second buckle, and the outer side has a snap-fit ​​plate. The second buckle hooks onto the back edge of the circuit board for snap-fit ​​connection. The snap-fit ​​plate is aligned with the front of the outer shell on the same vertical plane. The inner side of the first surrounding plate has a first buckle, and the outer side has an adhesive plate. The first buckle hooks onto the back of the snap-fit ​​plate for snap-fit ​​connection. The adhesive plate has multiple through holes.

[0005] With the above structure, the control panel is bonded to the oven using adhesive at the bonding plate. For maintenance, the control panel can be removed from the oven by physically scraping or injecting organic solvent through the through-hole to dissolve the adhesive. Pressing the second latch plate against the outside of the mounting cavity causes the second enclosure to deform due to its own flexibility. This, combined with the movement of the second latch, misaligns the circuit board with the back edge, allowing the circuit board to be removed from the mounting cavity opening and separated from the outer casing for repair. Pressing the first latch against the outside of the receiving cavity again... The enclosure deforms due to its own toughness, and in conjunction with the movement of the first buckle and the offset of the back edge of the latching plate, the outer shell can be removed from the cavity opening. The outer shell can then be separated from the transparent cover for maintenance of the buttons or touch panels on both, making the operation relatively convenient. It realizes the sequential connection of the transparent cover, outer shell, and circuit board with latches. The first buckle hooks onto the latching plate, locking the outer shell in place within the cavity, and the second buckle hooks onto the circuit board, locking it in place within the mounting cavity. Disassembly or assembly can be completed simply by pushing the latches, facilitating maintenance after disassembly.

[0006] As a further improvement of this utility model, the inner side of the second enclosure is also provided with a limiting reinforcing rib. The limiting reinforcing rib includes a supporting part and a limiting part. The supporting part abuts against the front edge of the circuit board, and the limiting part abuts against the side of the circuit board.

[0007] With the above structure, the supporting part of the limiting reinforcing rib abuts against the front edge of the circuit board, and the second buckle prevents the circuit board from moving back and forth in the mounting cavity. The limiting part abuts against the side of the circuit board to prevent the circuit board from moving to the side, thus fixing the circuit board in all directions and avoiding the circuit connected to the whole machine from being disconnected due to the movement of the circuit board.

[0008] As a further improvement of this utility model, the front of the outer shell is also provided with a positioning slot, and the inner wall of the receiving cavity is provided with a protruding positioning block, the position and size of which match the positioning slot.

[0009] With the above structure, while the transparent cover is snapped to the outer shell, the positioning block is inserted into the positioning slot. The positioning block abuts against the inner wall of the positioning slot to prevent the outer shell from moving to the side within the receiving groove.

[0010] As a further improvement of this utility model, the positioning slot narrows on the side facing the back of the housing to form a trapezoidal structure, and the positioning block is a trapezoidal block that matches the shape of the positioning slot.

[0011] With the above structure, the positioning slot narrows on the side facing the back of the shell to form a trapezoidal structure. The positioning block is a trapezoidal block that matches the shape of the positioning slot. It can be inserted from the narrower end of the positioning block through the wider slot on the positioning slot, making it easier for the positioning block to be aligned and enter the positioning slot.

[0012] As a further improvement of this utility model, the first buckle is a first right-angled trapezoidal block with its short side away from the first enclosure, and the inclined surface of the first right-angled trapezoidal block faces the opening of the receiving cavity; the second buckle is a second right-angled trapezoidal block with its short side away from the second enclosure, and the inclined surface of the second right-angled trapezoidal block faces the opening of the mounting cavity.

[0013] With the above structure, the inclined surface of the first right-angled trapezoidal block faces the cavity opening, and the inclined surface of the second right-angled trapezoidal block faces the cavity opening. During assembly, the inclined surfaces can be squeezed by pushing the edges of the outer shell and the circuit board, which in turn pushes the first and second buckles to the side to be offset, and then passes over the buckles to enter the cavity. Afterwards, the buckles are reset by the toughness of the first and second surrounding plates, and the buckle connection is completed without having to push the buckles open separately.

[0014] As a further improvement of this utility model, the first enclosure is provided with a first movable opening and a first elastic support plate. The first support plate is located at the first movable opening and connected to one side edge of the first movable opening. A first buckle is connected to the first support plate. The second enclosure is provided with a second movable opening and a second elastic support plate. The second support plate is located at the second movable opening and connected to one side edge of the second movable opening. A second buckle is connected to the second support plate.

[0015] With the above structure, the first support plate is set in the first movable opening and the second support plate is set in the second movable opening, so that the first support plate and the second support plate have sufficient space to undergo elastic deformation. The first buckle and the second buckle are correspondingly set on the first support plate and the second support plate, making it easier to push the first buckle and the second buckle to bend the corresponding support plate, reducing the difficulty of pushing the buckle, and also preventing the first plate and the second plate from being directly squeezed and damaged.

Detailed Implementation

[0020] like Figures 1-3 An oven control panel is shown, including a transparent cover 1, an outer shell 2, and a circuit board 3. The back of the transparent cover 1 has a receiving cavity 4 and a first surrounding plate 5 forming the side wall of the receiving cavity 4. The outer shell 2 is disposed in the receiving cavity 4. The back of the outer shell 2 has an installation cavity 6 and a second surrounding plate 7 forming the side wall of the installation cavity 6. The circuit board 3 is disposed in the installation cavity 6. The inner side of the second surrounding plate 7 has a second buckle 8 and the outer side has a snap-fit ​​plate 9. The second buckle 8 hooks onto the back edge of the circuit board 3 for snap-fit ​​connection. The snap-fit ​​plate 9 is aligned with the front of the outer shell 2 on the same vertical plane. The inner side of the first surrounding plate 5 has a first buckle 10 and the outer side has an adhesive plate 11. The first buckle 10 hooks onto the back of the snap-fit ​​plate 9 for snap-fit ​​connection. The adhesive plate 11 has multiple through holes 12.

[0021] The control panel is bonded to the oven body by applying glue to the bonding plate 11. For maintenance, the control panel can be removed from the oven body by physically scraping or injecting organic solvent into the through-hole 12 to dissolve the glue. By pressing the second latch 8 plate against the outside of the mounting cavity 6, the second enclosure 7 deforms due to its own toughness. This, combined with the movement of the second latch 8, offsets the back edge of the circuit board 3, allowing the circuit board 3 to be removed from the cavity opening of the mounting cavity 6 and separated from the outer casing 2 for maintenance. Then, by pressing the first latch 10 against the outside of the receiving cavity 4, the first enclosure 5 deforms due to its own toughness. The body's toughness deforms, and the first buckle 10 moves and is offset from the back edge of the latching plate 9, allowing the outer shell 2 to be removed from the cavity of the receiving cavity 4. The outer shell 2 can then be separated from the transparent cover 1, and the buttons or touch panels on both can be repaired. The operation is relatively convenient. The transparent cover 1, the outer shell 2 and the circuit board 3 are connected by buckles in sequence. The first buckle 10 hooks the latching plate 9 and locks the outer shell 2 in the receiving cavity 4. The second buckle 8 hooks the circuit board 3 and locks it in the mounting cavity 6. Disassembly or assembly can be completed by simply pushing the buckles, which is convenient for disassembly and repair.

[0022] The inner side of the second enclosure 7 is also provided with a limiting reinforcing rib 13, which includes a supporting part 14 and a limiting part 15. The supporting part 14 abuts against the front edge of the circuit board 3, and the limiting part 15 abuts against the side of the circuit board 3.

[0023] The supporting part 14 of the limiting reinforcing rib 13 abuts against the front edge of the circuit board 3, and the second buckle 8 prevents the circuit board 3 from moving back and forth in the mounting cavity 6. The limiting part 15 abuts against the side of the circuit board 3 to prevent the circuit board 3 from moving to the side, thus fixing the circuit board 3 in all directions and preventing the circuit connected to the whole machine from being disconnected due to the movement of the circuit board 3.

[0024] The front of the outer casing 2 is also provided with a positioning slot 16, and the inner wall of the receiving cavity 4 is provided with a protruding positioning block 17. The position and size of the positioning block 17 match the positioning slot 16.

[0025] While the transparent cover 1 is snapped into the outer shell 2, the positioning block 17 is inserted into the positioning slot 16. The positioning block 17 abuts against the inner wall of the positioning slot 16 to prevent the outer shell 2 from moving to the side within the receiving groove.

[0026] The positioning slot 16 narrows to form a trapezoidal structure on the side facing the back of the housing 2, and the positioning block 17 is a trapezoidal block that matches the shape of the positioning slot 16.

[0027] The positioning slot 16 narrows on the side facing the back of the housing 2 to form a trapezoidal structure. The positioning block 17 is a trapezoidal block that matches the shape of the positioning slot 16. The narrower end of the positioning block 17 can be inserted into the wider slot on the positioning slot 16, making it easier for the positioning block 17 to be aligned and enter the positioning slot 16.

[0028] The first buckle 10 is a first right-angled trapezoidal block with its short side away from the first enclosure 5, and the inclined surface of the first right-angled trapezoidal block faces the cavity opening of the receiving cavity 4. The second buckle 8 is a second right-angled trapezoidal block with its short side away from the second enclosure 7, and the inclined surface of the second right-angled trapezoidal block faces the cavity opening of the mounting cavity 6.

[0029] With the inclined surface of the first right-angled trapezoidal block facing the opening of the receiving cavity 4 and the inclined surface of the second right-angled trapezoidal block facing the opening of the mounting cavity 6, during assembly, the inclined surfaces can be squeezed by pushing the edges of the outer shell 2 and the circuit board 3, which in turn pushes the first buckle 10 and the second buckle 8 to the side to be offset, and then passes over the buckle to enter the cavity. Then, relying on the toughness of the first surrounding plate 5 and the second surrounding plate 7, the buckle is driven to reset, and the buckle connection is completed without having to push the buckle open again.

[0030] The first enclosure 5 has a first movable opening 18 and a first elastic support plate 19. The first support plate 19 is located at the first movable opening 18 and connected to one side edge of the first movable opening 18. The first buckle 10 is connected to the first support plate 19. The second enclosure 7 has a second movable opening 20 and a second elastic support plate 21. The second support plate 21 is located at the second movable opening 20 and connected to one side edge of the second movable opening 20. The second buckle 8 is connected to the second support plate 21.

[0031] The first support plate 19 is set in the first movable opening 18, and the second support plate 21 is set in the second movable opening 20, so that the first support plate 19 and the second support plate 21 have sufficient space to undergo elastic deformation. The first buckle 10 and the second buckle 8 are correspondingly set on the first support plate 19 and the second support plate 21, making it easier to push the first buckle 10 and the second buckle 8 to bend the corresponding support plate, reducing the difficulty of pushing the buckle, and also preventing the first enclosure plate 5 and the second enclosure plate 7 from being directly squeezed and damaged.
