Technical Field

The utility model relates to the field of ovens of kitchen appliances, in particular to an automatic rotating cage coupling device of an air oven and the air oven comprising the automatic rotating cage coupling device.

Background

An oven is a sealed electric appliance for cooking food or drying food, and is classified into a home oven and an industrial oven. The household oven is a food cooking appliance commonly used in daily life of people, can process food materials in a mode of baking food, and is convenient for people to eat. The oven is widely applied in daily household 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 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 adopts a radiation heating mode or a mode of heating in combination with air, a radiation area of heat radiation or an area covered by hot air flow is limited to a part of the surface of food, if food is not properly stirred in a cooking process, only a part of the food corresponding to a heating area can be contacted with enough high-temperature radiation or air flow to enable the food to be completely cooked, and parts of the food in other areas are not contacted with enough high temperature and are not cooked frequently. 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 rotating cage arranged in the box body of the air oven is of a hollow cylindrical structure and is provided with a side surface and two bottom surfaces. 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 food into the rotating cage, then close the rotating cage and turn on the oven for heating. 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 in the current market has the problem of easy locking under the working condition of high temperature, and in addition, the rotating cage is difficult to take out from the air oven when being locked without a resetting device. In addition, under the transmission mode of prior art, the problem that the motor drive rotating cage in-process still has the easy slip still, influences the durability of air oven to the user experience of product has been influenced.

Therefore, a revolving cage device with reasonable design needs to be provided for the air oven, and the durability and the reliability of the revolving cage device can be ensured while the function of turning over food in the cooking process can be realized.

The present invention may be embodied in many different forms and is not limited to the embodiments described herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art. It should be noted that: the relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments should be construed as merely exemplary, and not limiting, unless otherwise specified.

It should also be noted that in the following description of the embodiments, four types of directional descriptive terms, i.e., "upper/upper," "lower/lower," "outer/outer," and "inner/inner," or similar thereto, will be used. Wherein "up/above" and "down/below" are defined as relative concepts of up and down generated in the longitudinal height direction of the air oven with reference to the longitudinal height direction, and both directions of "up/above" and "down/below" are directed as vectors, with an angle therebetween of 180 degrees; "outside/outside" and "inside/inside" are defined as the relative concepts of outside and inside that are generated in a direction perpendicular to the plane in which the vertical cooking cavity wall of the air oven is located with the vertical cooking cavity wall of the air oven as a reference plane, wherein the concept of "outside/outside" corresponds to the side that is vertically directed to the outside of the air oven with the panel of the vertical cooking cavity wall of the air oven as the starting plane, and "inside/inside" corresponds to the side that is vertically directed to the inside of the air oven with the panel of the vertical cooking cavity wall of the air oven as the starting plane.

The coupling function of the automatic coupling device for the rotating cage is realized by the return spring in the coupler assembly. Referring to fig. 5a, 5b, 5c, 6a, 6b, 6c and 9, wherein fig. 5a, 5b and 5c show a perspective view and a top and side view cross-section, respectively, of a drive wheel in a coupler assembly of an air oven of the present invention, fig. 6a, 6b and 6c show a perspective view and a top and side view cross-section, respectively, of a drive coupler in a coupler assembly, and fig. 9 shows a cross-sectional view of an air oven. The automatic coupling device of the rotating cage consists of a motor 1, a coupler assembly, a fixed support 5 and a rotating cage assembly 6, wherein the coupler assembly comprises a driving wheel 2, a return spring 3 and a driving coupler 4.

When the automatic coupling device of the rotating cage is combined into a whole, the motor 1 is connected with the driving wheel 2. As shown in fig. 1, the motor 1 further includes a motor shaft 1a, a motor upper fixing hole 1c, a motor lower fixing hole 1d, and a driving wheel fixing groove 1 b. Correspondingly, as shown in fig. 5a, the driving wheel 2 further includes a motor shaft fixing hole 2a and a driving wheel tooth 2b, when the motor 1 is connected to the driving wheel 2, the motor shaft fixing hole 2a is sleeved on the outer surface of the driving wheel fixing groove, and the connection between the motor 1 and the driving wheel 2 is realized by a threaded connection. When the motor 1 rotates axially, the motor 1 can drive the transmission wheel 2 to rotate anticlockwise or clockwise synchronously and axially.

The transmission coupler 4 is slidably sleeved on the outer surface of the transmission wheel 2. As shown in fig. 5b and fig. 6b, when the two are sleeved together, the outer surface of the driving wheel 2 and the inner surface of the driving coupler 4 are engaged with each other, so that the driving wheel 2 can drive the driving coupler 4 to make synchronous axial rotation along with the rotation of the motor shaft 1 a. Furthermore, as shown in fig. 5a and 5b, a plurality of transmission gear teeth 2b are provided on the outer surface of the transmission wheel 2, which are evenly distributed on the outer side wall of the transmission wheel 2. In a preferred embodiment, the number of transmission teeth 2b is 4. As shown in fig. 6b, a plurality of driving wheel tooth spaces 4c are provided on the inner surface of the driving coupling 4, and in order to achieve the intermeshing effect, it is preferable that the number of driving wheel tooth spaces 4c corresponds to the number of driving gear teeth 2b and is 4. When the transmission coupler 4 is sleeved outside the transmission wheel 2, the transmission wheel teeth 2b are embedded with the transmission wheel tooth grooves 4 c. In this manner, the transmission coupler 4 cannot perform axial rotational movement independently of the transmission wheel 2, and therefore the axial rotational movement of the two is performed simultaneously. However, the drive coupling 4 is slidable relative to the drive wheel 2 in a direction relative to an axis about which both rotate axially.

Referring now to fig. 3 and 4, fig. 3 is a perspective view showing the separated state of the motor 1, the coupler assembly and the fixing bracket 5 of the automatic coupling device for a rotating cage, and fig. 4 is a side view showing a sectional view of the motor 1, the coupler assembly and the fixing bracket 5 in the combined state. As shown in fig. 3, the motor 1 is connected to the driving wheel 2 from the outside, the return spring 3 is sleeved on the outer surface of the driving wheel 2, and the driving coupler 4 is engaged with the driving wheel teeth 2b through the driving wheel tooth space 4c, so that the driving coupler 4 is slidably sleeved on the outer surface of the driving wheel 2, and the return spring 3 is sandwiched between the inner side surface of the motor 1 and the outer side surface of the driving coupler 4. Further, the motor 1 is disposed outside the fixed bracket 5 such that the coupler assembly is interposed between an inner surface of the motor 1 and an outer surface of the fixed bracket 5. Since the fixing bracket 5 is further provided with the limiting bin 51 protruding towards the inner side, specifically, after the automatic coupling device of the rotating cage is assembled, the coupler assembly is accommodated in the space formed by the limiting bin 51 and the inner side surface of the motor.

As shown in fig. 9, the transmission coupler 4 is detachably connected to the rotating cage assembly, when the transmission teeth 2b of the transmission wheel 2 are engaged with the tooth spaces 4c of the transmission wheel, the transmission wheel 2 can drive the transmission coupler 4 to axially rotate, and the transmission coupler 4 further drives the rotating cage assembly 6 to axially rotate. Meanwhile, the axial rotation does not affect the sliding of the transmission coupler 4 in the inward or outward direction relative to the transmission wheel 2 in the limiting bin 51 along the axial direction of the axial rotation. Due to the connection among the driving wheel 2, the return spring 3 and the transmission coupler 4, the transmission coupler 4 realizes sliding motion relative to the driving wheel 2 under the action of restoring force of the return spring 3 to the second direction or pushing force to the first direction. Furthermore, the driving coupling 4 is detachably connected to the cage assembly 6, and when the motor 1 drives the driving wheel 2 to rotate axially, the driving wheel 2 correspondingly drives the driving coupling 4 to rotate axially further through the mutual engagement of the driving gear teeth 2b and the driving wheel tooth grooves 4c, and simultaneously the driving coupling 4 further transmits the axial power to the cage assembly to drive the cage assembly 6 to rotate axially.

In a preferred embodiment, reference is also made to fig. 2a, 2b and 6c for specific cooperation of the return spring 3 and the coupler assembly, wherein fig. 2a is a schematic perspective view of the fixing bracket 5, fig. 2b is a schematic sectional view of the fixing bracket at a side view, and fig. 6c is a schematic sectional view of the transmission coupler 4 in the coupler assembly at a side view. As can be seen from fig. 6c, the coupler 4 is cylindrical, and the longitudinal surface of the cylinder has a step due to different radii, and the step formed by the position of the step is defined as a coupler stop protrusion 4 b. As shown in fig. 2a and 2b, an annular limiting bin ring 51b is disposed on the top peripheral edge of the limiting bin 51 corresponding to the coupler limiting protrusion 4 b.

In operation, the outer side (i.e. the side pointing to the outside of the air oven, i.e. the side on which the motor 1 is arranged with respect to the vertical wall of the cooking chamber) is defined as the first direction, and when the transmission coupling 4 is pushed in this first direction, the transmission coupling 4 slides in the first direction with respect to the transmission wheel 2 and compresses the return spring 3 to contract in the first direction. By doing so, the coupler 4 is separated from the cage assembly 6, so that the motor 1 and the cage assembly 6 cannot be connected to the coupler assembly to achieve power transmission, and the cage assembly 6 can be taken out of the air oven. After the transmission coupler 4 and the rotating cage assembly are separated from each other, the automatic rotating cage coupling device can realize automatic coupling through the design adopted by the utility model. Specifically, the return spring 3 interposed between the transmission wheel 2 and the coupler 4 is compressed, and tries to push the transmission coupler 4 inward (i.e. the side of the vertical wall of the cooking cavity inside the air oven, which is opposite to the first direction) due to the spring restoring force, and cannot push the coupler to move further in the second direction after the return spring 3 pushes the transmission coupler 4 to reach a limit position, which is defined as a position where the coupler limit protrusion 4b contacts the limit bin ring 51 b. In this position, the annular coupler limiting protrusion 4b with a fall is blocked by the limiting bin ring 51b, so that the transmission coupler 4 cannot continuously slide towards the second direction, and due to the pushing action of the return spring 3 on the transmission coupler 4, the transmission coupler 4 is re-engaged with the rotating cage assembly 6, so that the motor 1 and the rotating cage assembly 6 are connected through the coupler assembly again to realize power transmission, and the rotating cage assembly 6 cannot be taken out of the air oven at this time.

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, and the transmission coupler 4 further includes a first rotating rod bayonet 4a (shown in fig. 6a) corresponding to the first rotating rod 6 c. When the first rotating rod 6c is sleeved in the first rotating rod bayonet 4a, the transmission coupler 4 and the rotating cage assembly 6 are connected with each other, and at the moment, the transmission coupler 4 can drive the rotating cage assembly 6 to axially rotate under the axial power provided by the driving wheel 2 driven by the motor 1.

When the return spring 3 is not acted by external force, the first rotating rod 6c and the first rotating rod bayonet 4a are in a mutually connected state, and the connection between the two is tight and cannot be loosened due to the pressing of the return spring 3. When the return spring 3 is acted by an external force of a user pushing the transmission coupler 4 to the first direction, the transmission coupler 4 slides relative to the transmission wheel 2 to the first direction, so that the first rotating rod 6c is separated from the first rotating rod bayonet 4a, and the separation work of the rotating cage automatic coupling device is completed. At this time, the return spring 3 is pressed by the external force to apply a reaction force, which is applied to the outer side surface of the transmission coupler 4. Therefore, in a state where the first rotating rod 6c and the first rotating rod notch 4a are separated from each other, under the action of the reaction force of the spring, the return spring 3 drives the transmission coupler 4 to slide relative to the transmission wheel 2 in the second direction, so that the first rotating rod 6c and the first rotating rod notch 4a are connected with each other, and the return action of the automatic rotating cage coupling device is completed.

In addition, the assembly of the automatic coupling device of the rotary cage with the air oven requires the cooperation of the vertical wall 7 of the cooking cavity, the fixed support 5 and the bottom plate 9. Referring to fig. 2a, 8 and 9, fig. 2a shows a perspective view of the fixing bracket 5, fig. 8 shows a perspective view of the vertical wall of the cooking cavity, and fig. 9 shows a sectional view of the automatic coupling device of the rotating cage when it is installed with respect to the air oven. The fixed support 5 comprises a fixed support transmission wheel hole 5a, a fixed support upper fixed hole 5b and a fixed support lower fixed hole 5c, and the cooking cavity vertical wall 7 comprises a cooking cavity vertical wall transmission wheel hole 7a, a motor fixed hole 7b, a cooking cavity first vertical wall 7c, a second rotating rod bayonet 7d, a screw fixed hole 7e and a cooking cavity second vertical wall 7 f.

As shown in fig. 8, in a preferred embodiment, the cooking cavity first vertical wall 7c and the cooking cavity second vertical wall 7f are respectively disposed on two sides of the cooking cavity vertical wall 7, wherein a cooking cavity vertical wall transmission wheel hole 7a is disposed on the cooking cavity first vertical wall 7c, a second rotating rod bayonet 7d is disposed on the cooking cavity second vertical wall 7f, and the rotating cage assembly 6 further includes a second rotating rod 6d, when the motor 1 drives the rotating cage assembly 6 to rotate, the first rotating rod 6c is connected with the transmission coupler 4 in an engageable manner, and on one side of the cooking cavity second vertical wall 7f, the second rotating rod 6d is clamped on the second rotating rod bayonet 7d, so as to limit a moving manner of the second rotating rod 6d, and the second rotating rod 6d can only cooperate with the motor 1 to rotate axially.

As shown in fig. 2 and 10, in a preferred embodiment, the coupler assembly is sandwiched between the fixing bracket 5 and the inner side wall of the motor 1, the motor 1 is disposed on the outermost side of the automatic coupling device, and if the fixing bracket 5 is used as a reference, the motor 1 and the fixing bracket 5 sandwich the coupler assembly between the motor 1 and the outer side wall of the fixing bracket 5. The motor upper fixing hole 1c and the motor lower fixing hole 1d are fixedly connected with the fixing support 5 in a screw fastening mode. When the fixing support 5 is combined with the first vertical wall of the cooking cavity, the fixing hole 5b on the fixing support and the fixing hole 5c under the fixing support are fixed on the outer surface of the first vertical wall of the cooking cavity in a threaded connection mode, and the convex limiting bin 51 extends out of the transmission wheel hole 7a of the vertical wall of the cooking cavity into the inner side of the air oven. In the preferred embodiment, since the user needs to push the transmission coupler 4 to the outside and allow the return spring 3 to push the transmission coupler 4 to the inside, a cavity is correspondingly reserved between the restraining bin 51 and the inner side surface of the motor 1 for the transmission coupler 4 to move in the cavity, the moving direction being preferably perpendicular to the first standing wall 7c of the cooking chamber.

In the preferred embodiment, when the motor 1, the transmission wheel 2, the transmission coupler 4, the fixing bracket 5, and the first vertical cooking cavity wall 7c are assembled and connected to the basket assembly 6, the extension line of the motor shaft 1a in the rotation axis direction, the extension line of the transmission wheel 2 in the rotation axis direction, the extension line of the transmission coupler 4 in the rotation axis direction, the extension line of the first rotating rod 6c in the rotation axis direction, and the extension line of the second rotating rod 6d in the rotation axis direction coincide with each other and pass through the center of the transmission wheel hole 5a of the fixing bracket. 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 automatic rotating cage 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 the inside of the air oven generates high temperature and high heat during operation, although theoretically, a user can take out the rotating cage by pushing the transmission coupler to the first direction by hands. 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. Therefore, the utility model is also additionally provided with the rotating cage clamp 8, and the rotating cage clamp 8 is matched with the rotating cage assembly 6 for use, so that the rotating cage taking and placing work is easy and quick. The specific design of the rotating cage clamp 8 needs to combine fig. 9 with fig. 10a, 10b and 10c, where fig. 10a is a schematic perspective view of the rotating cage clamp 8, fig. 10b is a side view of the rotating cage clamp, and fig. 10c is a top view of the rotating cage clamp. The rotating cage clamp 8 comprises a first hook structure 8e and a second hook structure 8f which are bent downwards and have upward hook heads, and a rotating cage clamp handle 8a for being held by a user, wherein if a geometric symmetry line of the rotating cage clamp 8 is taken as a reference, the first hook structure 8e and the second hook structure 8f are arranged in a mirror image relative mode. The first turning lever 6c is further provided with a first turning lever hooking groove 6e surrounding the turning lever, corresponding to the first hooking structure 8e, and the second turning lever 6d is further provided with a second turning lever hooking groove 6f, corresponding to the second hooking structure 8 f. The user is getting the in-process of putting rotating cage subassembly 6, presss from both sides 8 and rotating cage subassembly 6's combination through the rotating cage, realizes pressing from both sides 8 through the rotating cage and gets and put the purpose of rotating cage, and the combination of rotating cage clamp 8 and rotating cage subassembly 6 is through imbedding first crotch structure 8e among the first bull stick hook groove 6e to imbed second crotch structure 8f second bull stick hook groove 6f and realize.

In the preferred embodiment, when the user removes the air oven, the user first simultaneously engages the first and second hook structures 8e and 8f into the first and second pivot hook slots 6e and 6f, respectively, while the tumble clamp 8 controls the tumble assembly 6 to move laterally.
