Technical Field
[0001] This utility model belongs to the field of electric baking pans and relates to a mechanism for preventing accidental power-on of an electric baking pan. Background Technology
[0002] An electric baking pan is a cooking appliance that heats the pan using an electric heating element to grill or fry food. To better control the pan's temperature, a temperature control probe is installed on the plug to sense the pan's temperature and control the switch accordingly. Traditionally, an electric baking pan is powered on simply by plugging in the temperature control plug. This means that even if the pan is not placed on the base, it will still be powered on when the temperature control plug is inserted. Summary of the Invention
[0003] To address the aforementioned problems, this utility model provides a mechanism to prevent accidental power-on of an electric baking pan. This mechanism has the advantage that the temperature control rod cannot be inserted when the baking pan is removed from the base, thereby preventing accidental power-on.
[0004] The purpose of this utility model is achieved as follows:
[0005] An electric baking pan anti-accidental power-on mechanism includes a base, a baking pan, and a temperature control plug. The baking pan is detachably placed on the base. A temperature control box for inserting the temperature control plug is fixedly connected to one side of the baking pan. The temperature control plug also includes a temperature control rod. A temperature control slot for inserting the temperature control rod is formed in the temperature control box at the lower end of the baking pan. A limit seat is fixed inside the temperature control box. Limit grooves are formed on both sides of the limit seat. A limit sliding piece is slidably disposed in the limit groove. A spring is connected to the upper end of the limit sliding piece. The upper end of the spring abuts against the upper inner wall of the temperature control box, and the lower end of the spring abuts against the limit sliding piece. The temperature control box has an opening at the lower end relative to the limit seat. A top piece is fixed to the base relative to the opening. The top piece passes through the opening and abuts against the lower end of the limit sliding piece. When the baking pan is placed on the base, the top piece lifts the limit sliding piece to allow the temperature control rod to be inserted. When the baking pan is removed from the base, the top piece and the limit sliding piece separate, and the spring pushes the limit sliding piece downward to block the insertion of the temperature control rod.
[0006] With the above settings, when the baking tray and the base are separated, the top plate and the limiting sliding plate separate. The limiting sliding plate moves downward under the action of the spring and blocks the temperature control slot. At this time, the temperature control rod cannot be inserted, preventing the temperature control rod from being inserted and accidentally turning on the power when the baking tray and the base are separated.
[0007] The present invention is further configured such that: the two sides of the limiting sliding piece extend into limiting grooves to form lifting ends, and there are two lifting pieces, which respectively abut against the lower ends of the two lifting ends.
[0008] With the above settings, the lifting end of the limiting sliding piece is set on both sides of the limiting slide groove, and the top piece can be set on both sides of the limiting seat, which makes it convenient for the top piece to move up and down relative to the limiting seat, thereby lifting the limiting sliding piece, making the structure more reasonable.
[0009] The present invention is further configured such that: the limiting seat includes a bottom positioning plate, and side plates are provided on both sides of the top positioning plate, the limiting slide groove is provided on the side plates, and the upper end of the limiting seat is fixedly connected to the upper wall of the temperature control box.
[0010] The bottom positioning plate can be used to locate the position of the limit sliding piece as it slides down, thus ensuring that the limit sliding piece blocks the temperature control slot when it slides down.
[0011] The present invention is further configured such that the limiting seat is U-shaped.
[0012] The present invention is further configured such that: the upper end of the limiting sliding piece is formed with a spring groove, and the lower end of the spring is locked in the spring groove.
[0013] The spring slot design makes the connection between the spring and the limiting slide plate more stable and reduces the risk of detachment.
[0014] The present invention is further configured such that: the lower end of the limiting sliding piece is provided with an arc-shaped relief groove.
[0015] The design of the arc-shaped relief groove makes it easier to insert the temperature control rod when the top plate lifts the limiting sliding plate. Even if the top plate and the limiting sliding plate wear down during long-term use, making the distance the limiting sliding plate is lifted still a little short, the temperature control rod can still be inserted.
[0016] The present invention is further configured such that the limiting seat and the temperature control slot are correspondingly arranged, and the limiting seat is formed with a through groove for the temperature control rod to pass through.
[0017] The present invention is further configured such that: an electric heating element is fixed at the lower end of the baking pan, and the electric connector of the electric heating element is located inside the temperature control box and electrically connected to the temperature control plug.
[0018] The present invention is further configured such that: a grounding plate is fixed at the lower end of the temperature control slot and electrically connected to the temperature control rod.
[0019] The present invention is further configured such that: the baking tray has an oil outlet hole formed on it, and an oil storage box is provided on the base corresponding to the oil outlet hole.
[0020] The above settings facilitate the handling of waste oil.
[0021] The outstanding and beneficial technical effect of this invention compared with the prior art is that when the baking tray and the base are separated, the top plate and the limiting sliding plate are separated. The limiting sliding plate moves downward under the action of the spring and blocks the temperature control slot. At this time, the temperature control rod cannot be inserted, preventing the temperature control rod from being inserted and accidentally turning on the power when the baking tray and the base are separated.

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0034] An electric baking pan anti-accidental power-on mechanism includes a base 1, a baking pan 2, and a temperature control plug 3. The baking pan 2 is detachably placed on the base 1. A temperature control box 4 for inserting the temperature control plug 3 is fixedly connected to one side of the baking pan 2. The temperature control plug 3 also has a temperature control rod 5. A temperature control slot 6 for inserting the temperature control rod 5 is formed at the lower end of the baking pan 2 corresponding to the temperature control box 4. A limit seat 7 is fixed inside the temperature control box 4. Limit grooves 8 are formed on both sides of the limit seat 7. A limit sliding piece 9 is slidably arranged in the limit groove 8. A spring 10 is connected to the upper end of the limit sliding piece 9. The upper end of the spring 10 abuts against the upper inner wall of the temperature control box 4, and the lower end of the spring 10 abuts against the limiting sliding plate 9. The temperature control box 4 has an opening 11 at the lower end relative to the limiting seat, and the base 1 has a top plate 12 fixed relative to the opening 11. The top plate 12 passes through the opening 11 and abuts against the lower end of the limiting sliding plate 9. When the baking tray 2 is placed on the base 1, the top plate 11 lifts the limiting sliding plate 9 to allow the temperature control rod 5 to be inserted. When the baking tray 2 leaves the base 1, the top plate 11 and the limiting sliding plate 9 separate, and the spring 10 pushes the limiting sliding plate 9 down to block the insertion of the temperature control rod 5.
[0035] With the above settings, when the baking tray 2 and the base 1 are separated, the top plate 12 and the limiting sliding plate 9 are separated. The limiting sliding plate 9 moves downward under the action of the spring 10. The limiting sliding plate 9 blocks the temperature control slot 6. At this time, the temperature control rod 5 cannot be inserted, preventing the temperature control rod 5 from being inserted and accidentally turning on the power when the baking tray 2 and the base 1 are separated.
[0036] The limiting sliding piece 9 extends from both sides into limiting grooves 8 to form lifting ends 13. There are two top pieces 12, which respectively abut the lower ends of the two lifting ends 13. With the above arrangement, the lifting ends 13 of the limiting sliding piece 9 are located on both sides of the limiting groove 9, and the top pieces 12 can be located on both sides of the limiting seat 7, which facilitates the vertical movement of the top pieces 12 relative to the limiting seat 7, thereby lifting the limiting sliding piece 9, resulting in a more reasonable structure.
[0037] The limiting seat 7 includes a bottom positioning plate 14, and side plates 15 are provided on both sides of the top positioning plate 14. The limiting slide groove 8 is provided on the side plate 15, and the upper end of the limiting seat 7 is fixedly connected to the upper wall of the temperature control box 4. By setting the bottom positioning plate 14, the position of the limiting slide piece 9 when it slides down can be positioned, thereby ensuring that the limiting slide piece 9 blocks the temperature control slot 6 when it slides down.
[0038] The limit seat 7 is U-shaped.
[0039] The upper end of the limiting sliding piece 9 is formed with a spring groove 16, and the lower end of the spring 10 is locked in the spring groove 16. The spring groove 16 makes the connection between the spring 10 and the limiting sliding piece 9 more stable and reduces the risk of detachment.
[0040] The lower end of the limiting sliding piece 9 is also provided with an arc-shaped relief groove 17. With the design of the arc-shaped relief groove 17, it is easier to insert the temperature control rod 5 when the top piece 12 lifts the limiting sliding piece 9. Even if the top piece 12 and the limiting sliding piece 9 are worn during long-term use, so that the distance to which the limiting sliding piece 9 is lifted is still a little short, the temperature control rod 5 can still be inserted.
[0041] The limiting seat 7 and the temperature control slot 6 are respectively provided, and the limiting seat 7 is formed with a through groove 18 for the temperature control rod to pass through.
[0042] A heating element 19 is fixed to the lower end of the baking pan. The electrical connector 20 of the heating element is located inside the temperature control box and is electrically connected to the temperature control plug.
[0043] The lower end of the temperature control slot 6 is fixed with a grounding plate 21, which is electrically connected to the temperature control rod 5.
[0044] The baking tray 2 has oil outlet holes 22 formed on it, and an oil collection box 23 is provided on the base corresponding to the oil outlet holes. The above configuration facilitates the disposal of waste oil.
[0045] This invention features a temperature control rod that cannot be inserted when the baking pan is removed from the base, thus preventing accidental power-on.
[0046] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
