The oven is widely applied in daily family use, provides convenience for the life of people, improves the life quality of people and is popular with users. An industrial oven is a device used in industry to dry products, and is also called oven, drying box, etc. The oven is an electric heating appliance for baking food by using radiation heat emitted by an electric heating element, and can be used for making roast chicken, roast duck, baked bread, cakes and the like. The temperature of the oven is typically adjusted from 50 degrees celsius to 250 degrees celsius depending on the needs of the baked goods. In addition, a new type of oven, called an "air oven," has also been developed in recent years. The air oven is a cooking appliance for baking food by using a circulating air flow of hot air emitted by an air heating assembly and a fan. Air ovens are commonly used to process certain pasta, such as bread, pizza, or snacks such as egg tarts, cookies, and the like.

While existing ovens consist essentially of an outer shell, an inner cavity, and a heating element, air ovens typically also include an air heating element. In the oven in the prior art, no matter the oven is heated by radiation or is heated by matching with air, the radiation area of the heat radiation or the area covered by the hot air flow is limited to part of the surface of the food, if the food is not properly stirred in the cooking process, only the part of the food corresponding to the heating area can be contacted with enough high-temperature radiation or air flow to completely cook the food, and the part of the food in other areas is not contacted with enough high temperature to be frequently cooked. Therefore, the user must turn the food once every certain period of time to uniformly heat all the areas of the food, but such manual turning operation causes considerable inconvenience to the user.

In order to solve the problems, the air oven in part of the prior art realizes the function of turning over food by additionally arranging a rotating cage.

The auxiliary device of the rotating cage further comprises a rotating shaft driven by the synchronous motor, the rotating shafts are arranged on two bottom surfaces of the rotating cage, are connected with the vertical wall of the cooking cavity through the rotating shafts, and are driven by the motor to rotate. When using an air oven with a rotating cage, it is first necessary to fill the food into the rotating cage, then close the rotating cage and turn on the oven to heat. In prior art rotary basket devices, the air oven operates to sufficiently heat the food by tumbling in the rotary basket. Nevertheless, the rotating cage of the air oven on the market at present has the problem of easily blocking under the operating condition of high temperature, and in addition, does not have resetting means, and the rotating cage is difficult to take out from the air oven when blocking. In addition, under prior art's transmission mode, there is still the oil smoke and the problem of food steam leakage in the inboard revolving cage pivoted in-process of the motor drive culinary art chamber outside the culinary art chamber, brings the pollution to the inside electronic components of air oven to influence the durability of air oven.

As shown in fig. 9, when the two are sleeved together, the outer side surface of the transmission wheel 2 contacts with the inner surface of the sealing ring 3, so that the transmission wheel 2 can make synchronous axial rotation relative to the sealing ring 3 along with the rotation of the motor shaft 1a, and the sealing ring 3 does not move or rotate. As shown in fig. 5a and 5b, a plurality of seal rings 3b are provided on the inner surface of the seal ring 3, and the seal rings 3b have an annular shape and uniformly surround the inner side wall of the seal ring 3. In a preferred embodiment, the number of sealing collars 3b is 3. As shown in fig. 6a and 6b, the outer surface of the driving wheel 2 is smooth, so that the outer surface of the driving wheel 2 is influenced by friction as little as possible when rotating relative to the sealing collars 3b, and meanwhile, the multi-layer blocking of contaminants such as oil stain, water vapor and the like in the cooking cavity is realized through the form that the sealing collars 3b are respectively contacted with the outer side surface of the driving wheel 2.

By adopting such a contact mode, the transmission wheel 2 can independently make axial rotation movement relative to the sealing ring 3, so that the transmission wheel 2 can make axial rotation movement simultaneously under the coating sealing protection of the sealing ring 3. The relative positions of the transmission wheel 2 and the seal ring 3 in the direction of the axis about which the transmission wheel and the seal ring axially rotate are fixed.

Further, please refer to fig. 3 and fig. 4 together, wherein fig. 3 shows a schematic diagram of relative positions of the motor 1, the first coupling assembly and the fixing bracket 5 of the rotating cage sealing coupling device when they are in a separated state, and fig. 4 shows a cross-sectional view of the motor 1, the first coupling assembly, the fixing bracket 5, the sealing ring 3, the driving wheel 2 and the first rotating rod 6c when they are in a combined state. As shown in fig. 3, the motor 1 is connected to the driving wheel 2 from the outside, the sealing ring 3 is sleeved on the outer surface of the driving wheel 2, the sealing ring 3 contacts the outer surface of the driving wheel 2 through the sealing sleeve ring 3, so that the driving wheel 2 is rotatably sleeved on the inner surface of the sealing ring 3, the sealing ring 3 is clamped between the inner side surface of the motor 1 and the outer side surface of the driving wheel 2, and the driving wheel 2 is isolated from the motor 1 through the sealing ring 3. In addition, since the motor 1 is disposed outside the fixing bracket 5, and the fixing bracket 5 needs to clamp the sealing ring 3 between the inner surface of the fixing bracket 5 and the outer surface of the first vertical cooking cavity wall, the inner side of the fixing bracket 5 is correspondingly provided with a positioning ring 51 which is matched with the sealing ring 3 and has a recess, and specifically, after the assembly of the rotating cage sealing coupling device is completed, the sealing ring 3 is accommodated in a space formed by the positioning ring 51 and the outer side of the first vertical cooking cavity wall 7 c.

When the driving wheel 2 is connected to the motor shaft 1a through the first rotating rod bayonet 2a and the first rotating rod 6c is detachably sleeved in the first rotating rod bayonet 2a, the motor shaft 1a can drive the driving wheel 2 to rotate axially, and the driving wheel 2 further drives the rotating cage assembly 6 to rotate axially. At this time, the axial rotation of the driving wheel 2 does not affect the sealing ring 3 to rotate together with the driving wheel 2.

Further, referring to fig. 3, 7 and 9, fig. 7 shows a perspective view of the cage assembly 6. As shown in fig. 3 and 9, the coupling device for a sealing of a rotating cage further comprises a second coupling assembly cooperating with and operating together with the first coupling assembly, the second coupling assembly comprising a fixed base 4 and a return spring 4c, and the rotating cage assembly 6 further comprising a removably connected rotating cage end cover 6b and a second rotating rod 6d. Specifically, the first rotating rod and the second rotating rod are respectively arranged at two ends of the rotating cage assembly 6, and the rotating cage assembly 6 is supported by the two ends to rotate axially.

Specifically, the fixed base 4 is disposed at the center of the outer surface of the cage end cover 6b, and the fixed base 4 is connected to the cage end cover by means of a threaded connection. A second swing lever catch 4a that penetrates in the lateral direction and that completely accommodates the return spring 4c therein is provided inside the fixed base 4. When the fixed base 4 is combined with the return spring 4c and the second rotating rod 6d, the second rotating rod 6d is sleeved in the second rotating rod bayonet 4a, and at this time, two ends of the spring body of the return spring 4c are respectively defined by the innermost end of the second rotating rod 6d and the outer side surface of the rotating cage end cover 6b. By such a connection, as shown in fig. 7, the rotating cage 6a of the rotating cage assembly 6 and the second rotating rod 6d are connected with each other, so that the rotating cage assembly 6 can drive the second rotating rod 6d to rotate axially. In a state where the second rotating rod 6d is fitted in the second rotating rod receiving portion 4a, the second rotating rod 6d is slidable in the second rotating rod receiving portion 4a relative to the cage assembly 6 in the axial direction of the axial rotation thereof.

Preferably, the specific cooperation between the first coupling assembly and the motor 1, the fixing bracket 5 and the first standing wall 7c of the cooking cavity refers to fig. 2a, fig. 2b and fig. 4, wherein fig. 2a and fig. 2b are respectively schematic perspective views of the fixing bracket 5 at different angles. As shown in fig. 2a and 2b, the fixing bracket 5 further includes a second driving wheel hole 5a, the fixing bracket 5 is fixed to the outer surface of the cooking chamber first standing wall 7c through the fixing bracket fixing hole 5b, preferably in a screw coupling manner, and the fixing bracket 5 sandwiches the sealing ring 3 between the inner surface of the fixing bracket 5 and the outer surface of the cooking chamber first standing wall 7 c. In order to enable the motor 1 to still realize axial driving on the driving wheel 2, the fixing support 5 is further provided with a second driving wheel hole 5a, the sealing ring 3 is arranged at the position of the second driving wheel hole 5a in a buckling mode, and the driving wheel 2 is accommodated on the inner side of the sealing ring 3 through the second driving wheel hole 5 a. In addition, the fixing support 5 is further provided with a motor fixing column 5c and a motor positioning groove 51b which is slightly recessed, the motor 1 is fixed to the position of the motor fixing column 5c in a threaded connection mode through a first motor fixing hole and a second motor fixing hole respectively, and the inner side surface of the motor 1 is just arranged in the positioning groove 51b, so that the motor 1 and the fixing support 5 are combined more tightly.

Further, as shown in the perspective view of the rotating cage assembly in fig. 7, the rotating cage assembly 6 includes a rotating cage 6a, a rotating cage end cover 6b, a first rotating rod 6c and a second rotating rod 6d. In correspondence with the first turning bar 6c, the transmission wheel 2 further comprises a first turning bar notch 2a (shown in fig. 6 a). When the first rotating rod 6c is sleeved in the first rotating rod bayonet 2a, the driving wheel 2 is connected with the rotating cage assembly 6, and at the moment, the driving wheel 2 can drive the rotating cage assembly 6 to rotate axially under the axial power provided by the driving wheel 2 driven by the motor 1.

Specifically, in a state where the first rotating rod 6c and the first rotating rod bayonet 2a are connected to each other, the outer side (i.e., the side where the second coupling assembly is located and directed to the outside of the air oven) is defined as a first direction, and when the rotating cage assembly 6 is pushed to slide in the first direction relative to the second rotating rod 6d, the return spring 4c is compressed and is retracted in the second rotating rod bayonet 4 a. By doing so, the first rotating rod 6c is separated from the first rotating rod bayonet 2a, so that the motor 1 and the rotation cage assembly 6 can no longer realize power transmission through the connection of the first coupling assembly, and the rotation cage assembly 6 can be taken out of the air oven. With drive wheel 2 and rotating cage subassembly 6 after the alternate segregation, the sealed coupling device of rotating cage then accessible the utility model discloses a design realization automatic coupling. Specifically, referring to fig. 9, the return spring 4c, which is sandwiched between the second pivot rod 6d and the cage end cover 6b, is compressed and tends to urge the cage assembly 6 inwardly (i.e., on the side of the cooking chamber standing wall inside the air oven, in a direction opposite to the first direction) due to the spring restoring force. When the return spring 4c pushes the cage assembly 6 to the limit position, the cage assembly 6 cannot be pushed to move continuously to the second direction, and the limit position is just the position where the first rotating rod 6c is combined with the first rotating rod notch 2a of the driving wheel 2. In this second-direction limit position, the drive wheel 2 is re-engaged with the cage assembly 6, so that the motor 1 and the cage assembly 6 are again connected by the first coupling assembly to enable power transmission, and the cage assembly 6 cannot be removed from the air oven at this time.

Specifically, when the return spring 4c is not acted by an external force, the first rotating rod 6c and the first rotating rod bayonet 2a are connected with each other, and the connection between the two is tight and cannot be loosened due to the pressing of the return spring 4 c. When the return spring 4c is acted by an external force of a user for pushing the rotating cage assembly 6 to the first direction, the rotating cage assembly 6 slides relative to the driving wheel 2 to the first direction, so that the first rotating rod 6c is separated from the first rotating rod clamping opening 2a, and the separation work of the rotating cage sealing coupling device is completed. At this time, the return spring 4c is urged by the external force to apply a reaction force, and the reaction force is applied to the outer side surface of the cage cover 6b. Therefore, in a state where the first rotating rod 6c and the first rotating rod notch 2a are separated from each other, the return spring 4c drives the rotating cage assembly 6 to slide relative to the driving wheel 2 in the second direction based on the action of the spring reaction force, so that the first rotating rod 6c and the first rotating rod notch 2a are connected with each other, and thus the rotating cage returning action of the rotating cage sealing coupling device is completed.

On the other hand, the assembly of the coupling device with the air oven also requires the cooperation of the vertical cooking cavity wall 7, the fixing support 5 and the bottom plate 9. Referring to fig. 2a, 8 and 9, wherein fig. 2a shows a perspective view of the fixing support 5, fig. 8 shows a perspective view of the vertical wall of the cooking cavity, and fig. 9 shows a sectional view of the rotating cage sealing coupling device when mounted with respect to the air oven. The fixed support 5 comprises a second transmission wheel hole 5a, a fixed hole 5b and a motor fixed column 5c on the fixed support, and the cooking cavity vertical wall 7 comprises a first transmission wheel hole 7a, a first cooking cavity vertical wall 7c, a second rotating rod fixing hole 7d, a screw fixing hole 7e and a second cooking cavity vertical wall 7f.

Preferably, as shown in fig. 8, a cooking cavity first standing wall 7c and a cooking cavity second standing wall 7f are respectively disposed on two sides of the cooking cavity standing wall 7, wherein the cooking cavity first standing wall 7c is provided with a first driving wheel hole 7a, the cooking cavity second standing wall 7f is provided with a second rotating rod fixing port 7d, and the rotating cage assembly 6 further comprises a second rotating rod 6d, when the rotating cage assembly 6 is driven by the motor 1 to rotate, the first rotating rod 6c is connected with the driving wheel 2 in an engageable manner, and on one side of the cooking cavity second standing wall 7f, the second rotating rod 6d is clamped on the second rotating rod fixing port 7d, so as to limit the moving manner of the second rotating rod 6d, and enable the second rotating rod 6d to only cooperate with the motor 1 to rotate axially.

Preferably, as shown in fig. 2a, 5 and 9, the sealing ring 3 is interposed between the fixed support 5 and the side wall outside the first standing wall 7c of the cooking chamber, and the motor 1 is provided outside the fixed support 5. With the sealing ring 3 as a reference, the sealing ring 3 is sandwiched between the first standing wall 7c of the cooking chamber and the fixing bracket 5. Through the first fixed orifices 1c of motor and motor second fixed orifices 1d to the mode of screw fastening is connected with motor fixed column 5c on the fixed bolster 5. When the fixing support 5 is combined with the first vertical wall 7c of the cooking cavity, the fixing support fixing hole 5b on the fixing support 5 is fixed on the outer side surface of the first vertical wall 7c of the cooking cavity in a threaded connection mode, and at the moment, the transmission wheel 2 just extends into the sealing ring 3 from the second transmission wheel hole 5 a.

In the preferred embodiment, when the motor 1, the transmission wheel 2, the fixed base 4, the fixed support 5, the first upright cooking chamber wall 7c and the second upright cooking chamber wall 7f are completely assembled and connected to the basket assembly 6, the axis of rotation of the motor shaft 1a, the transmission wheel 2, the fixed base 4, the first rotating rod 6c and the second rotating rod 6d are all coaxial and with the second transmission wheel hole 5 a. Therefore, when the motor 1 drives the rotating cage assembly 6 to rotate, the power transmission cannot be lost due to the change of the axis direction of the rotating shaft, the early abrasion of the rotating cage sealing coupling device is avoided, and the durability of the product is improved.

Referring to fig. 9 in addition to fig. 8, the bottom surface of the air oven is further provided with a bottom plate 9, and an opening for fixing screws is opened on the upper surface of the bottom plate 9, and correspondingly, a plurality of screw fixing holes 7e are also opened on the bottom surface of the cooking cavity standing wall 7. Therefore, the cooking chamber vertical wall 7 is fixedly connected to the bottom plate 9 through a plurality of screw fixing holes 7e by means of screws.

Since high temperature and high heat are generated inside the air oven during operation, the user can take out the rotation cage assembly 6 by pushing the rotation cage assembly to the first direction by hands in theory. However, the basket assembly 6 has a high surface temperature due to cooking heat, and is easily burned by a user, so that such an operation scheme is not practically feasible.
