Ovens, as an appliance for baking food, have gradually come into the field of view of the public in recent years. The household electric oven is an electric heating appliance for baking food by utilizing radiant heat emitted by an electric heating element, and can be used for making baked chicken, baked duck, baked bread, cakes and the like. The temperature of the electric oven can be adjusted within the range of 50-250 ℃ according to different requirements of the baked food.

The heating consistency is required to be ensured when the oven is used for baking food, and the food cooking consistency is generally ensured by means of adjusting the structural form of a heating pipe, a flow field in a cavity and the like in the process of baking food in the electric oven in the market at present; when large meat food needs to be roasted, tools such as a roasting fork and the like need to be used for rotating the food so as to improve the roasting uniformity of the food.

However, for food with flat shape such as cookies and pizza, the tool cannot be used for rotating, the difference of heat radiation between food near the heating tube and food far from the heating tube cannot be solved by adjusting the structural shape of the heating tube, and the influence of the food shape on the air flow cannot be eliminated by adjusting the flow field of the cavity. For food with such a shape, a baking tray of some ovens is provided with a driving structure which can enable the baking tray to rotate, but the existing driving structure is generally positioned above the baking tray, and the driving structure can influence the flow direction of hot air in the ovens during the food cooking process; meanwhile, the metal driving structure generates metal debris due to abrasion in the long-term use process, and the metal debris may fall into the baking tray and harm the body health of a user.

Based on this, the utility model provides an overware subassembly to when baking the flat food of appearance such as biscuit, pizza in alleviating some technologies, the rotatory drive structure of drive overware can influence the hot-air flow direction in the oven in the rotatable overware structure, uses for a long time and still has metal piece to drop the overware, influences the healthy technical problem of user.

The embodiment of the present invention provides a bakeware assembly, as shown in fig. 1 and 2, comprising a rotating member, a driving device and a bakeware 100; the rotating piece is arranged below the baking tray 100; the rotating piece is provided with a first toothed sheet 200, the bottom of the baking tray 100 is provided with a second toothed sheet 300, the second toothed sheets 300 are distributed in a circular ring shape, and the first toothed sheet 200 is meshed with the second toothed sheet 300; the driving device is used for driving the rotating piece to rotate.

Through the utility model discloses, set up in overware 100 bottom and rotate the piece, drive arrangement can rotate through driving and rotate the rotation that drives first tooth piece 200 on the piece to the rotation that drives overware 100 is driven through the meshing of first tooth piece 200 and second tooth piece 300. The whole transmission mechanism has a simple structure and small occupied space, and the flow of hot air in the oven cannot be influenced, so that the uniformity of heating food is not influenced; meanwhile, the transmission mechanism is arranged at the bottom of the baking tray 100, so that metal scraps possibly generated in use can not fall into the baking tray 100. The utility model discloses when having alleviated the flat food of appearance such as baking biscuit, pizza, the rotatory drive structure of drive overware 100 can influence the hot-air flow direction in the oven in the rotatable overware 100 structure of current, uses for a long time and still has metal piece to drop overware 100, influences the healthy technical problem of user.

In this embodiment, the transmission of the rotating member and the baking tray 100 is accomplished by the engagement of the first tooth piece 200 and the second tooth piece 300, and the first tooth piece 200 and the second tooth piece 300 are the transmission of the gear 400. Specifically, the distance between every two adjacent first tooth plates 200 is equal, and the distance between every two adjacent second tooth plates 300 is equal. In the present embodiment, a plurality of second teeth 300 are disposed perpendicular to the bottom of the baking tray 100, and the center of the circle formed by the plurality of second teeth 300 is the same as the center of the bottom plate of the baking tray 100.

It should be noted that the second tooth plate 300 may not be provided in the above-described manner. For example, the second tooth plate 300 can be a bevel gear 400 disposed at the bottom of the bakeware 100, in which case, the rotating member should also be provided with the bevel gear 400, and the first tooth plate 200 is the tooth of the bevel gear 400 on the rotating member. The first and second tooth plates 200 and 300 can be of other structures as long as the transmission of the rotating member and the baking tray 100 can be completed.

In this embodiment, as shown in fig. 3 and 4, the rotating member includes a gear 400, and the first tooth plate 200 is a tooth of the gear 400. It should be noted that the arrangement of the gear 400 is preferred in this embodiment, the first tooth blade 200 may also be directly arranged on the rotating member, and the arrangement of the gear 400 may enable the relative position of the first tooth blade 200 and the rotating member to be adjustable, and simplify the manufacturing process of the rotating member.

Specifically, the rotating member further includes a rotating shaft 500, the gear 400 is disposed on the rotating shaft 500, and the driving device is in transmission connection with the rotating shaft 500 to drive the rotating shaft 500 to rotate. The gear 400 is sleeved on the rotating shaft 500, and the relative position of the gear 400 and the rotating shaft 500 can be adjusted according to requirements.

Alternatively, as shown in fig. 1, the rotating shaft 500 is parallel to the bottom of the bakeware 100, and the axis of the gear 400 is perpendicular to the axis of the circular ring formed by the plurality of second gear plates 300. In general, the driving device cannot be installed inside the oven due to insufficient high temperature resistance, and therefore, the driving device should be installed outside the oven. Specifically, the driving device is disposed outside the sidewall of the oven, and the rotation shaft 500 passes through the sidewall of the oven and is connected to the driving device. In this case, only the rotation shaft 500 is disposed inside the oven and at the bottom of the grill pan 100, and the occupied space is small, and the flow of hot air inside the oven is not substantially affected.

On the other hand, when it is necessary to roast food such as roast duck in the oven, the grill 600 and the grill pan 100 can be taken out, and the rotation shaft 500 can be replaced with a roasting fork, thereby further enhancing the versatility of the oven.

Alternatively, as shown in fig. 6, the rotating shaft 500 is vertically arranged with the bottom of the bakeware 100, and the axis of the gear 400 is parallel to the axis of the circular ring formed by the plurality of second teeth 300. In this case, since the driving device cannot be disposed inside the oven due to insufficient high temperature resistance, an isolation layer needs to be disposed at the bottom of the oven, the driving device needs to be disposed inside the isolation layer, and the rotating shaft 500 passes through the upper surface of the isolation layer to be connected to the driving device inside the isolation layer. Only the rotating shaft 500 is arranged inside the oven, so that the occupied space is small, and the flow of hot air in the oven is not influenced basically.

In this embodiment, the grill plate assembly further includes a grill 600, and the grill plate 100 is disposed on the grill 600. A first limiting member is disposed on the baking tray 100, a second limiting member is disposed on the baking rack 600, and the first limiting member and the second limiting member cooperate to limit the relative movement between the baking tray 100 and the baking rack 600 on the plane where the baking rack 600 is located. The reason for limiting the relative movement between grill 600 and grill 100 on the plane on which grill 600 is located is to ensure that first toothed plate 200 and second toothed plate 300 can be engaged with each other, and the transmission between rotary shaft 500 and grill 100 is not affected by the displacement of grill 100.

Specifically, as shown in fig. 2 to 4, the first limiting member is an annular protrusion 110 disposed at the bottom of the bakeware 100 and downward, and the bottom end of the annular protrusion 110 is lower than the bottom end of the first tooth piece 200. In general, the center of the outer ring of the annular protrusion 110 is concentric with the outer ring of the grill pan 100, the annular protrusion 110 is disposed at the bottom of the grill pan 100, and the second tooth 300 is directly disposed on the annular protrusion 110. When the rotation shaft 500 drives the baking tray 100 to rotate, the annular protrusion 110 also rotates along with the rotation shaft, which mainly limits the horizontal displacement of the annular protrusion 110 on the rotation plane, and ensures that the annular protrusion 110 always rotates around the same axis, i.e. the engagement between the first tooth piece 200 and the second tooth piece 300 is ensured, the bottom end of the annular protrusion 110 is lower than the bottom end of the first tooth piece 200, so that the interference between the second tooth piece 300 and the baking tray can be avoided under the condition that the main supporting surface of the baking tray 600 is a flat surface, and the main supporting surface of the baking tray can better support the food to be baked when the baking tray is not used.

Alternatively, as shown in fig. 2 to 4, the second stopper is an annular bead 610 disposed on the upper surface of the grill 600, and the inner diameter of the annular bead 610 is larger than the outer diameter of the annular protrusion 110. The height of the ring steel ring 610 should be higher than the height of the ring-shaped protrusion 110, and the inner diameter of the ring steel ring 610 is slightly larger than the outer diameter of the ring-shaped protrusion 110, so that the ring-shaped protrusion 110 can rotate within the range of the ring steel ring 610 and will not be stuck due to contact or friction; however, if the inner diameter of the ring steel ring 610 is too large than the outer diameter of the ring protrusion 110, the moving range of the ring protrusion 110 is too large to achieve the limiting effect. Specifically, the difference between the diameters should be smaller than the width of the first tooth plate 200 or the second tooth plate 300.

Optionally, the second limiting members are protrusions that are arranged on the upper surface of the grill 600 at intervals and have the same height, the protrusions are distributed in a circular ring shape, and the inner diameter of a circular ring formed by the protrusions is larger than the outer diameter of the annular protrusion 110. When the outer ring of the first limiting member is a continuous ring, the outer ring of the second limiting member does not need to be a continuous ring, as long as the annular protrusion 110 can be limited. Specifically, the number of the protrusions is at least 3, and the distance between every two adjacent protrusions is smaller than the diameter of the annular protrusion 110, so that the annular protrusion 110 can be limited. The inner diameter of the ring formed by the plurality of protrusions should be slightly larger than the outer diameter of the ring-shaped protrusion 110, and the difference between the diameters should be smaller than the width of the first tooth plate 200 or the second tooth plate 300.

Optionally, the driving device is a rotisserie motor 700. It should be noted that the rotisserie motor 700 should be located outside the oven because the high temperature resistant properties of the rotisserie motor 700 are not sufficient to support its placement inside the oven.

Further, a mounting hole is formed on the rotary baking motor 700, and the mounting hole can be matched with the end of the rotary shaft 500. In this embodiment, the rotating shaft 500 is a square shaft, so that the square mounting hole is directly formed on the transferring and baking motor 700, and the transmission between the rotating shaft 500 and the transferring and baking motor 700 can be realized by inserting one end of the rotating shaft 500 into the mounting hole. It should be noted that the rotating shaft 500 may not be a square shaft in this embodiment, in this case, the rotating shaft 500 may not be provided with a mounting hole, and other mechanisms capable of rotating the rotating shaft 500 may be provided, as long as the transmission between the rotating shaft 500 and the rotating shaft 700 is realized, and the rotating shaft 500 is driven by the rotating shaft 700 to rotate.

The utility model discloses still provide a cooking device with toast the function, as shown in fig. 5, including top heating pipe, hot-blast convection current subassembly 800, collateral branch strut 900 and above-mentioned overware subassembly. Specifically, in order to allow the rotating shaft 500 in the cooking appliance to be inserted into the rotary baking motor 700 outside the cooking appliance, a through hole needs to be formed in a corresponding side of the cooking appliance. When it is required to use the horizontal rotation function of the cooking appliance, the grill 600 is disposed on a designated floor height of the side support frame 900, and then one end of the rotation shaft 500 is inserted into the broiling motor 700 located at the outer side of the cooking appliance through the above-mentioned through hole. After the food is placed in the grill 100, the grill 100 is placed on the grill 600 at a predetermined position, that is, the annular protrusion 110 is positioned to correspond to the annular rim 610, so that the first and second teeth 200 and 300 are engaged with each other. After the cooking appliance is started, the rotary baking motor 700 drives the rotary shaft 500 to axially rotate, the rotary shaft 500 drives the gear 400 to rotate, and the first tooth piece 200 and the second tooth piece 300 on the gear 400 are driven to realize the horizontal rotation of the baking tray 100.
