Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to an electric oven with a power-off structure. Background Technology

[0002] As people continuously innovate their cooking methods and raise their demands for food quality, electric ovens have become one of the most widely used baking appliances. Existing electric ovens generally consist of a base and a top cover, which work together to create a space for placing a baking tray. Heating mechanisms are then installed in both the base and the top cover to heat the tray. However, in existing electric ovens, the heating mechanism on the top cover may remain hot even after the cover is opened, posing a risk of burns to the user. Utility Model Content

[0003] In order to overcome the defects of the existing technology, this utility model provides an electric oven with a power-off structure to solve the above problems.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an electric oven with a power-off structure, including a base, a top cover and a connecting seat, the connecting seat being disposed on the base, a micro switch being disposed inside the connecting seat, the top cover being disposed of a rotating shaft and a power-off trigger, the rotating shaft being inserted into the connecting seat and rotatably connected to the connecting seat, so that when the rotating shaft rotates inside the connecting seat, it drives the power-off trigger to move towards or away from the spring of the micro switch; the power supply is electrically connected to the heating wire disposed on the top cover through the micro switch.

[0005] It is worth noting that the connector has a pivot hole, through which the rotating shaft passes and extends into the connector; the connector has an arc-shaped hole, which is arranged around the pivot hole, and the power-off trigger passes through the arc-shaped hole and extends into the connector, so that the power-off trigger moves along the extension direction of the arc-shaped hole; the micro switch is located at the end of the extension direction of the arc-shaped hole.

[0006] Preferably, the lower side of the connecting seat is connected to the base, the pivot hole and the arc-shaped hole are provided on the upper side of the connecting seat, and connecting seats are distributed on both sides of the top cover.

[0007] Optionally, the base is provided with a heating wire.

[0008] Specifically, the base is provided with a lower reflector, and the lower reflector and the heating wire disposed on the base are arranged sequentially from the inside to the outside in the base. The top cover is provided with an upper reflector, and the upper reflector and the heating wire disposed on the top cover are arranged sequentially from the inside to the outside in the top cover.

[0009] Preferably, the device also includes a baking tray, which is placed on the base, and the circumferential wall of the baking tray is provided with a handle.

[0010] The beneficial effects of this invention are as follows: In the electric oven with a power-off structure, when the top cover rotates and closes onto the base via the rotating shaft, the power-off contact moves towards the spring of the micro switch and presses against it, thus putting the micro switch in an on state. At this time, the heating wire of the top cover is energized and works. When the top cover rotates and flips open relative to the base via the rotating shaft, the power-off contact moves away from the spring of the micro switch, thus putting the micro switch in an off state. At this time, the heating wire of the top cover is de-energized and does not work, but the base can still heat normally. In this way, the user can avoid touching the top cover and being burned, ensuring the user's safety, and can continue to heat the food on the base, such as flipping the food or adding seasonings.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1-6 As shown, an electric oven with a power-off structure includes a base 1, a top cover 2, and a connecting seat 3. The connecting seat 3 is disposed on the base 1 and has a micro switch 4 inside. The top cover 2 has a rotating shaft 21 and a power-off trigger 22. The rotating shaft 21 is inserted into the connecting seat 3 and rotatably connected to the connecting seat 3, so that when the rotating shaft 21 rotates inside the connecting seat 3, it drives the power-off trigger 22 to move towards or away from the spring 41 of the micro switch 4. The power supply is electrically connected to the heating wire 5 disposed on the top cover 2 through the micro switch 4.

[0020] In the electric oven with a power-off structure, when the top cover 2 rotates and closes onto the base 1 via the rotating shaft 21, the power-off trigger 22 moves towards the spring 41 of the micro switch 4 and presses against the spring 41, thus putting the micro switch 4 in an on state. At this time, the heating wire 5 of the top cover 2 is energized and works. When the top cover 2 rotates and opens relative to the base 1 via the rotating shaft 21, the power-off trigger 22 moves away from the spring 41 of the micro switch 4, thus putting the micro switch 4 in an off state. At this time, the heating wire 5 of the top cover 2 is de-energized and does not work, but the base 1 can still heat normally. In this way, the user can avoid touching the top cover 2 and being burned, ensuring the user's safety, and can continue to heat the food on the base 1, such as flipping the food or adding seasonings.

[0021] Preferred, such as Figure 2 and 4As shown, the connecting seat 3 has a rotating shaft hole 31, through which the rotating shaft 21 passes and extends into the connecting seat 3; the connecting seat 3 has an arc-shaped hole 32, which is arranged around the rotating shaft hole 31, through which the power-off trigger 22 passes and extends into the connecting seat 3, so that the power-off trigger 22 moves along the extension direction of the arc-shaped hole 32; the micro switch 4 is located at the end of the extension direction of the arc-shaped hole 32. In this embodiment, the center of the rotating shaft hole 31 coincides with the center of the arc-shaped hole 32. The spring 41 of the micro switch 4 faces the end of the arc-shaped hole 32 in its extending direction. After the rotating shaft 21 rotates within the rotating shaft hole 31 and drives the power-off contact 22 towards the end of the arc-shaped hole 32 in its extending direction, the power-off contact 22 can contact the spring 41 of the micro switch 4, causing the spring 41 to deform and thus actuating the micro switch 4, changing the current on / off state. The power-off contact 22 is made of plastic, and a buffer pad 23 is fitted on the outer wall of the power-off contact 22 to prevent damage to the spring 41.

[0022] Optional, such as Figure 1-4 As shown, the lower side of the connecting seat 3 is connected to the base 1, the rotating shaft hole 31 and the arc-shaped hole 32 are provided on the upper side of the connecting seat 3, and connecting seats 3 are distributed on both sides of the top cover 2. Since the base 1 is located on the lower side of the top cover 2, this arrangement allows the rotating shaft hole 31 and the arc-shaped hole 32 to be positioned on the connecting seat 3 to correspond to the rotating shaft 21 and the power-off trigger 22 provided on the top cover 2.

[0023] Specifically, such as Figure 5 As shown, the base 1 is equipped with a heating wire 5. The heating wire 5, which is also provided on the top cover 2, can improve the heating efficiency of the space between the base 1 and the top cover 2.

[0024] It is worth noting that, such as Figure 5 As shown, the base 1 is provided with a lower reflector 11, and the lower reflector 11 and the heating wire 5 disposed on the base 1 are arranged sequentially from the inside to the outside in the base 1. The top cover 2 is provided with an upper reflector 24, and the upper reflector 24 and the heating wire 5 disposed on the top cover 2 are arranged sequentially from the inside to the outside in the top cover 2. In this embodiment, by providing the upper reflector 24 and the lower reflector 11, the food can be heated evenly, resulting in better taste.

[0025] Preferred, such as Figure 5 and 6 As shown, it also includes a baking tray 6, which is placed on the base 1. The circumferential wall of the baking tray 6 is provided with a handle 61. The baking tray 6 is designed to be detachable, so as to facilitate the removal of the baking tray 6 from the base 1 for cleaning and other operations. The handle 61 makes it easy to pick up the baking tray 6.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
