[0001] The utility model relates to barbecue stove technical field, especially a kind of electric oven. BACKGROUND

[0002] With the continuous innovation of cooking method, the increasing demand for food quality, electric oven has become one of the widely used baking cooking appliances. The existing electric oven generally includes base and top cover, the space for placing baking tray is formed by the cooperation of base and top cover, then heating mechanism is set on base and top cover to realize the purpose of heating food on baking tray. In actual use, since the heating mechanism is always in heating state, the temperature is relatively high, so the surface of top cover will also appear high temperature phenomenon. In addition, after opening the top cover, the heating mechanism of the top cover may still be working. In summary, the existing electric oven also has the problem that the top cover is easy to scald the user during use. SUMMARY

[0003] In order to overcome the defects of the prior art, the utility model provides an electric oven to solve the above problems.

[0004] The utility model discloses a technical scheme adopted to solve its technical problems: an electric oven, including base, top cover assembly and connecting seat.

[0005] The top cover assembly includes an outer shell, a partition cover and an inner cover arranged in sequence, so as to form a first heat insulation cavity between the outer shell and the partition cover, and a second heat insulation cavity between the partition cover and the inner cover.

[0006] The connecting seat is provided on the base, and a micro switch is arranged in the connecting seat. The outer shell is provided with a rotating shaft and a power-off touch element. The rotating shaft is inserted into the connecting seat and is rotatably connected with the connecting seat. When the rotating shaft rotates in the connecting seat, the power-off touch element is driven to move towards the direction of the elastic sheet close to or away from the micro switch. The power supply is electrically connected with the heating tube arranged on the top cover assembly through the micro switch.

[0007] Preferably, the outer shell extends rearward to form a protruding portion. A cavity formed in the protruding portion is in communication with the first heat insulation cavity. An upper heat dissipation hole is formed in the wall surface of the protruding portion.

[0008] Optionally, the rotating shaft and the power-off touch element are arranged on the outer wall of the protruding portion.

[0009] Specifically, the connector has a pivot hole, the rotating shaft passes through the pivot hole and extends into the connector; the connector has an arc-shaped hole, the arc-shaped hole is arranged around the pivot hole, 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.

[0010] It is worth noting that a lower reflector is provided on the side of the base near the top cover assembly, a lower heat insulation cavity is formed between the base and the lower reflector, and a lower heat dissipation hole is provided on the wall of the base, which is connected to the lower heat insulation cavity.

[0011] Optionally, a heating element is provided on the side of the inner cover near the base; a heating element is provided on the side of the base near the top cover assembly.

[0012] Specifically, a gap is formed between the heating element disposed on the side of the inner cover near the base and the heating element disposed on the side of the base near the top cover assembly, and the electric oven also includes a baking tray disposed in the gap.

[0013] The beneficial effects of this invention are as follows: In the electric oven, a dual-cavity unit is formed by the first and second heat insulation cavities. This dual-cavity unit prevents excessive heat transfer to the surface, thereby reducing the surface temperature. When the entire top cover assembly 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 the connected state. At this time, the heating element in the top cover assembly is energized and operates. When the entire top cover assembly 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 the disconnected state. At this time, the heating element in the top cover assembly is de-energized and does not operate. Thus, the user can avoid touching the top cover assembly and being burned, ensuring the user's safety. Attached Figure Description

[0021] 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.

[0022] like Figures 1-6 As shown, an electric oven includes a base 1, a top cover assembly 2, and a connecting seat 3;

[0023] like Figure 1 As shown, the top cover assembly 2 includes an outer shell 21, a partition cover 22, and an inner cover 23 arranged sequentially, so as to form a first heat insulation cavity between the outer shell 21 and the partition cover 22, and a second heat insulation cavity between the partition cover 22 and the inner cover 23; specifically, an inner cover 233 is installed inside the outer shell 211, and a partition cover 222 is provided between the inner cover 233 and the outer shell 211, thereby forming the first heat insulation cavity and the second heat insulation cavity;

[0024] like Figures 2-5 As shown, the connecting seat 3 is disposed on the base 1, and a micro switch 4 is provided inside the connecting seat 3. The outer shell 21 is provided with a rotating shaft 24 and a power-off contact 25. The rotating shaft 24 is inserted into the connecting seat 3 and rotatably connected to the connecting seat 3, so that when the rotating shaft 24 rotates inside the connecting seat 3, it drives the power-off contact 25 to move towards or away from the spring 41 of the micro switch 4. The power supply is electrically connected to the heating tube 5 disposed on the top cover assembly 2 through the micro switch 4.

[0025] In the electric oven, a dual-cavity unit is formed by the first and second heat-insulating cavities. This dual-cavity unit prevents excessive heat transfer to the surface, thereby reducing the surface temperature. When the entire top cover assembly 2 rotates via the rotating shaft 24 and closes onto the base 1, the power-off trigger 25 moves towards the spring 41 of the micro switch 4 and presses against it, thus putting the micro switch 4 in an on state. At this time, the heating element 5 in the top cover assembly 2 is energized and operates. When the entire top cover assembly 2 rotates via the rotating shaft 24 and flips open relative to the base 1, the power-off trigger 25 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 element 5 in the top cover assembly 2 is de-energized and does not operate, but the base 1 can still heat normally, continuing to heat the food on the base 1, such as flipping the food or adding seasonings. In this way, the user can avoid touching the top cover assembly 2 and being burned, ensuring the user's safety.

[0026] It is worth noting that, such as Figure 1 and 6 As shown, the outer shell 21 extends rearward to form a protrusion 211. The cavity formed in the protrusion 211 communicates with the first heat insulation cavity. An upper heat dissipation hole 212 is provided on the wall surface of the protrusion 211. The upper heat dissipation hole 212 allows heat to be dissipated from the first heat insulation cavity, further improving the heat insulation effect. Firstly, heat insulation is achieved through the first and second heat insulation cavities, preventing a large amount of heat from being transferred to the outer shell 21. Furthermore, the temperature inside the first heat insulation cavity near the outer shell 21 can be dissipated through the upper heat dissipation hole 212, preventing heat accumulation within the first heat insulation cavity.

[0027] Preferred, such as Figure 2 and 4 As shown, the rotating shaft 24 and the power-off trigger 25 are disposed on the outer wall of the protrusion 211. This allows the connecting seat 3 to be installed as far away from the first heat insulation cavity as possible. In this embodiment, the connecting seat 3 is not connected to either the first or second heat insulation cavity, thereby preventing heat from flowing into the connecting seat 3 and preventing the microswitch 4 inside the connecting seat 3 from being damaged due to prolonged high temperatures.

[0028] Optional, such as Figure 3 and 5As shown, the connecting seat 3 has a pivot hole 31, through which the rotating shaft 24 passes and extends into the connecting seat 3. The connecting seat 3 also has an arc-shaped hole 32, which is arranged around the pivot hole 31. The power-off trigger 25 passes through the arc-shaped hole 32 and extends into the connecting seat 3, allowing the power-off trigger 25 to move 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. The lower side of the connecting seat 3 is connected to the base 1, and the pivot hole 31 and the arc-shaped hole 32 are located on the upper side of the connecting seat 3. Connecting seats 3 are distributed on both sides of the base 1. 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 24 rotates within the rotating shaft hole 31 and drives the power-off contact 25 towards the end of the arc-shaped hole 32 in its extending direction, the power-off contact 25 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 25 is made of plastic, and a buffer pad 42 is fitted on the outer wall of the power-off contact 25 to prevent damage to the spring 41.

[0029] Specifically, such as Figure 1 and 6 As shown, a lower reflector 11 is provided on the side of the base 1 near the top cover assembly 2. A lower heat insulation cavity is formed between the base 1 and the lower reflector 11. A lower heat dissipation hole 13 is provided on the wall of the base 1, and the lower heat dissipation hole 13 communicates with the lower heat insulation cavity. The lower heat insulation cavity prevents excessive heat transfer to the surface of the base 1, thus preventing high temperatures. The lower heat dissipation hole 13 allows heat to escape from the lower heat insulation cavity, further improving the heat insulation effect. In this embodiment, by providing the lower reflector 11, food can be heated evenly, resulting in better taste.

[0030] It is worth noting that, such as Figure 1 As shown, a heating element 5 is provided on the side of the inner cover 23 near the base 1; a heating element 5 is also provided on the side of the base 1 near the top cover assembly 2. With the cooperation of the two heating elements 5, food can be heated from both the top and bottom, resulting in a good baking effect.

[0031] Specifically, such as Figure 1 and 6As shown, a gap is formed between the heating element 5 located on the side of the inner cover 23 near the base 1 and the heating element 5 located on the side of the base 1 near the top cover assembly 2. The electric oven also includes a baking tray 6, which is disposed in the gap. The circumferential wall of the baking tray 6 is provided with a handle 61. The baking tray 6 is designed to be detachable, making it easy to remove from the gap for cleaning and other operations. The handle 61 makes it easy to pick up the baking tray 6.

[0032] 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.
