According to the cooking utensil provided by the invention, materials such as rice and water are placed in the inner pot 20, high-pressure airflow is conveyed to the bottom of the inner pot 20 through the air inlet pipe or the telescopic device, so that the materials and the water can roll, collide, rub, rotate and the like under the action of the airflow, the purpose of automatic water washing is realized by utilizing pneumatic stirring, and the process of conveying the materials into the inner pot 20 after the cleaning is finished is omitted because the materials such as rice are directly washed in the inner pot 20, so that the problems that the materials such as rice are difficult to enter the pot and remain caused by the fact that the materials such as rice are washed outside the pot in the prior art are solved; compared with mechanical stirring, the air flow stirring is simpler in structure and more sanitary in cleaning; meanwhile, the output end of the air inlet pipe is connected with the telescopic device, and can move to the bottom of the inner pot 20 under the drive of the telescopic device to convey air flow or utilize the internal channel of the telescopic device to convey the air flow output by the air inlet pipe to the bottom of the inner pot, so that the air flow conveyed by the air inlet pipe or the telescopic device can rise upwards from the bottom of a mixture of materials and water, further the materials and water in the inner pot 20 are effectively driven to roll, and an effective stirring effect is achieved; and the telescopic device is arranged on the upper cover, so that the stability of the telescopic device is ensured.

In some embodiments of the present application, the telescopic device is merely used as a mechanical lifting structure for driving the output end of the air inlet pipe to move up and down by using the telescopic structure thereof, such as a scissor type lifting mechanism, a crank link mechanism and the like (not shown in the figure), wherein the output end of the air inlet pipe is preferably connected with the tail end of the telescopic device, moves up and down under the driving of the telescopic device, and can move to the bottom of the inner pot 20 to output air flow, and therefore the output of the air flow is independent of the telescopic device.

The telescopic device comprises a spring tube 50, wherein the spring tube 50 is sleeved on the hollow hose 30 and is tightly matched with the hollow hose 30, so that the spring tube 50 can inwards squeeze the soft hollow hose 30 to enable the hollow hose 30 to generate proper compression deformation (preferably, the outer wall surface of the hollow hose 30 is smooth), and a spring wire of the spring tube 50 can be properly embedded into the outer wall surface of the hollow hose 30 to be meshed with the hollow hose 30, thereby ensuring synchronous movement of the spring tube 50 and the hollow hose 30 and avoiding relative movement between the two; further, the driving component 60 drives the spring tube 50 to stretch and retract, namely the hollow hose 30 can be driven to stretch and retract, and further the up-and-down movement of the air inlet pipe output end in the inner pot 20 is realized, so that the automatic movement of the air inlet pipe output end can be realized through the driving component 60, and the automation degree of products is improved; in addition, the spring tube 50 also plays a certain role in protecting the hollow hose 30, and can avoid the conditions of friction and abrasion, collision and the like between the hollow hose 30 and other structures, thereby prolonging the service life of the hollow hose 30.

Specifically, the drive assembly 60 includes: a driving member and a driving wheel 62, the driving member being fixed to the upper cover 10; the driving wheel 62 is sleeved on the output shaft 611 of the driving member, and the circumferential side wall of the driving wheel is meshed with the spring tube 50 to drive the spring tube 50 to perform telescopic motion, as shown in fig. 1 to 5.

Further, the driving assembly 60 further includes: a driven pulley 63 rotatably mounted on the upper cover 10, and a gap for accommodating the spring tube 50 is formed between a circumferential side wall of the driven pulley 63 and a circumferential side wall of the driving pulley 62; wherein the spring tube 50 is inserted into the inner pan 20 through the gap and engaged with the driving wheel 62 and the driven wheel 63.

The driving assembly 60 comprises a driving member, a driving wheel 62 and a driven wheel 63, wherein the driving member provides a power source, the driving wheel 62 is sleeved on an output shaft 611 of the driving member and rotates along with the rotation of the output shaft 611; the driven wheel 63 is rotatably mounted on the upper cover 10, and a gap is formed between the side wall along the circumferential direction and the side wall along the circumferential direction of the driving wheel 62, the spring tube 50 penetrates through the gap and is engaged with the driving wheel 62 and the driven wheel 63, so that friction force is generated between the spring tube 50 and the driving wheel 62 and the driven wheel 63, and further force transmission is realized; because the outer contour of the spring tube 50 is wholly wavy, the cooperation of the spring tube and the driving wheel 62 and the driven wheel 63 forms a cooperation structure similar to a gear and a rack, so that the driving wheel 62 can drive the spring tube 50 to move along a linear direction when rotating, and the rotation of the output shaft 611 of the driving piece is converted into the linear motion of the spring tube 50; meanwhile, the linear motion of the spring tube 50 also drives the driven wheel 63 to rotate along the direction opposite to the driving wheel 62, and the arrangement of the driven wheel 63 can limit the spring tube 50 from being separated from the driving wheel 62, so that the effective engagement of the spring tube 50 and the driving wheel 62 is ensured, the use reliability of the driving assembly 60 is further ensured, and the sliding friction force borne by the spring tube 50 can be reduced, so that the movement resistance is reduced.

Of course, the driving assembly 60 may not include the driven wheel 63, so long as the engagement between the spring tube 50 and the driving wheel 62 can be ensured, the driving of the telescopic movement of the spring tube 50 can be realized, and the purpose of the present application is further achieved, for example, the driven wheel 63 is replaced by a smooth hard pressing plate, or a groove adapted to the spring wire of the spring tube 50 is formed on the driving wheel 62, which is not listed herein, and the embodiments can achieve the purpose of the present application without departing from the design concept and the spirit of the present application, and therefore, all the embodiments are within the scope of the present application.

Preferably, the axes of rotation of the driving wheel 62 and the driven wheel 63 are in a horizontal direction and parallel to each other, as shown in fig. 1 to 5.

The rotation axes of the driving wheel 62 and the driven wheel 63 are parallel to each other along the horizontal direction, so that the spring tube 50 needs to vertically pass through the gap between the driving wheel 62 and the driven wheel 63, and the rotation of the driving wheel 62 is directly converted into the linear motion of the spring tube 50 in the vertical direction, so that the structure is simpler; meanwhile, the input ends of the spring tube 50 and the hollow hose 30 can extend in the horizontal direction, so that the connection structure of the hollow hose 30 and the air source can be reasonably arranged according to the specific structure of the product, and the height of the cooking utensil can be reduced.

Of course, the rotation axes of the driving wheel 62 and the driven wheel 63 may also be along other directions, such as along a vertical direction, so that the spring tube 50 horizontally passes through a gap between the driving wheel 62 and the driven wheel 63 and is vertically bent and inserted into the inner pot 20, and when the driving wheel 62 rotates, the horizontal portion of the spring tube 50 is driven to perform telescopic motion, and then the vertical portion is indirectly driven to perform up-down telescopic motion; the rotation axes of the driving wheel 62 and the driven wheel 63 may not be parallel to each other, for example, may be at a certain angle, and the spring tube 50 may be clamped in the gap, so as to further drive the spring tube 50.

Preferably, the driving member is a motor 61, and the motor 61 is fixed to the upper cover 10 by a fastener, as shown in fig. 1 to 5.

Further, the driving wheel 62 and the driven wheel 63 are circumferentially provided with annular wheel grooves 64, and as shown in fig. 2, the spring tube 50 is inserted into the wheel grooves 64 and engaged with the groove walls of the wheel grooves 64.

Wherein, the driving wheel 62 and the driven wheel 63 are soft rubber wheels, and the spring tube 50 is pressed and embedded into the groove wall of the wheel groove 64 to be meshed with the groove wall of the wheel groove 64.

The driving wheel 62 and the driven wheel 63 are provided with annular wheel grooves 64 along the circumferential direction, the spring tube 50 is embedded into the wheel grooves 64 and is meshed with the groove walls of the wheel grooves 64, on one hand, the wheel grooves 64 play a certain limiting role on the spring tube 50, the spring tube 50 can be prevented from moving along the axial direction of the driving wheel 62 and/or the driven wheel 63, on the other hand, the groove walls of the wheel grooves 64 properly prolong the meshing length of the spring tube 50 with the driving wheel 62 and the driven wheel 63, so that the friction force between the spring tube 50 and the driving wheel 62 and the driven wheel 63 is increased, and the matching reliability of the spring tube 50 and the driving assembly 60 is further improved.

The driving wheel 62 and the driven wheel 63 are soft rubber wheels, so that the driving wheel 62 and the driven wheel 63 are easy to elastically deform under the action of external force, the spring tube 50 can be embedded into the wall of the wheel groove 64 through extrusion, and further the snap fit with the wall of the wheel groove 64 is realized, the structure is simpler, and the cost is lower.

Further, a bracket 70 is provided on the upper cover 10, an axle 71 is inserted on the bracket 70, and the driven wheel 63 is sleeved on the axle 71, as shown in fig. 1, 3 and 4.

The upper cover 10 is provided with a bracket 70, and the bracket 70 is inserted with a wheel axle 71, so that the driven wheel 63 is sleeved on the wheel axle 71, and can rotate relative to the upper cover 10. Specifically, the driven wheel 63 may be in interference fit with the axle 71, the axle 71 is in clearance fit with the bracket 70, and the rotation of the driven wheel 63 relative to the upper cover 10 is achieved through the relative rotation of the axle 71 and the bracket 70; alternatively, the driven wheel 63 is in clearance fit with the wheel axle 71, the wheel axle 71 is in interference fit with the bracket 70, and the relative rotation between the driven wheel 63 and the upper cover 10 is realized through the relative rotation between the driven wheel 63 and the wheel axle 71; of course, the driven wheel 63 may be in clearance fit with the axle 71, and the axle 71 may be in clearance fit with the bracket 70.

The working principle is as follows (taking cleaning rice as an example):

before rice washing, the spring tube 50 and the hollow hose 30 are in a contracted state, and the spray head 40 is tightly attached to the upper cover 10, as shown in fig. 3; when rice washing is started, the motor 61 rotates to drive the driving wheel 62 to rotate, the driving wheel 62 eats the spring tube 50 and pulls the spring tube 50 to move downwards, so that the spray head 40 reaches the bottom of the inner pot 20, as shown in fig. 4; after the spray head 40 reaches the bottom of the inner pot 20, rice and water enter the inner pot 20; after finishing the rice feeding and water feeding, a fan or a high-pressure air pump is started, so that air is sprayed out from each air outlet of the spray head 40 through the hollow hose 30; stirring the water-rice mixture by high-pressure gas to roll and rub the rice, thereby completing the cleaning of the rice; after the washing is completed and the rice washing water is discharged, the motor 61 is reversed, and the spring tube 50 is pulled to retract under the action of the driving wheel 62 and the driven wheel 63, so that the spray head 40 returns to the initial position, as shown in fig. 3; the above steps complete the rice washing and the retraction of the spray head 40.

Example two

The difference from the first embodiment is that: the groove wall of the wheel groove 64 is provided with a snap groove 65 adapted to the spring wire of the spring tube 50, and as shown in fig. 9 and 13, the spring wire is inserted into the snap groove 65 to snap the spring tube 50 with the groove wall of the wheel groove 64.

The engagement groove 65 which is matched with the spring wire of the spring tube 50 is directly formed on the groove wall of the wheel groove 64, so that the spring wire can be directly embedded into the engagement groove 65 and then tightly engaged with the groove wall of the wheel groove 64, the engagement depth is improved, and the engagement reliability of the spring tube 50 and the driving assembly 60 is further improved. Of course, in this case, the driving wheel 62 and the driven wheel 63 may be soft rubber wheels.

The working principle is the same as that of the first embodiment, and is not described herein.

Example III (as shown in FIGS. 6 to 17)

Further, on the basis of the second embodiment, a sliding hole 72 is formed in the bracket 70, and the wheel axle 71 is inserted into the sliding hole 72 and can slide reciprocally along the sliding hole 72, as shown in fig. 6 to 8; the support 70 is further provided with a floating limiting assembly 80 which abuts against the wheel axle 71, and as shown in fig. 6, 7, 10, 11, 12, 13, 14, 15, 16 and 17, the floating limiting assembly 80 can perform telescopic movement to enable the wheel axle 71 to slide along the sliding hole 72 so as to adjust the size of the gap, and the spring tube 50 is tightly meshed with the driving wheel 62.

Since the spring tube 50 and the hollow hose 30 are also accompanied by a proper amount of variation in the sectional dimensions during the telescopic movement, slip may occur when the sectional dimensions of the spring tube 50 and the hollow hose 30 are relatively small if the gap between the driving wheel 62 and the driven wheel 63 is relatively large, and deformation may be caused to affect the circulation of the air flow by pressing the spring tube 50 and the hollow hose 30 when the sectional dimensions of the spring tube 50 and the hollow hose 30 are relatively large if the gap between the driving wheel 62 and the driven wheel 63 is relatively small, and thus the size of the gap between the driving wheel 62 and the driven wheel 63 is very important for the telescopic movement of the spring tube 50 and the hollow hose 30. Based on this, this embodiment solves the above-mentioned problems by slidably setting the axle 71 and cooperating with the corresponding floating stopper assembly 80, so that the size of the gap can float following the variation of the sectional dimensions of the spring tube 50 and the hollow hose 30, so as to ensure that the size of the gap is adapted to the sectional dimensions of the spring tube 50 and the hollow hose 30 at the same time.

Specifically, the floating limiting assembly 80 is mounted on the bracket 70 and abuts against the wheel axle 71, and the wheel axle 71 is slidably inserted into the sliding hole 72, so that when the cross section size of the spring tube 50 and the hollow hose 30 changes in the moving process, the floating limiting assembly 80 performs corresponding telescopic movement so as to drive the wheel axle 71 to slide along the sliding hole 72, and further adjust the gap between the driven wheel 63 and the driving wheel 62, so that the hose deformation caused by too large gap or too small gap is avoided, the hollow hose 30 and the spring tube 50 can be more effectively promoted to be tightly meshed with the driving wheel 62, the spring tube 50 and the driving wheel 62 are ensured not to slip when relatively moving, and energy is effectively transferred; and the floating limiting assembly 80 abuts against the axle 71, so that the influence on the rotation of the driven wheel 63 can be avoided, and the driven wheel 63 and the axle 71 are preferably in clearance fit at the moment so as to ensure the free rotation of the driven wheel 63 as much as possible.

Wherein, the floating stop assembly 80 includes: a pushing member 81 and an elastic member. The pushing member 81 is slidably mounted on the bracket 70, and one end thereof abuts against the wheel shaft 71; the end of the support 70 away from the driving wheel 62 and the driven wheel 63 is provided with a baffle 74, and the elastic member is located between the other end of the pushing member 81 and the baffle 74 and abuts against the pushing member 81 and the baffle 74, as shown in fig. 7, 11, 13, 15 and 17.

The floating limiting assembly 80 comprises a pushing member 81 and an elastic member, wherein the pushing member 81 is slidably arranged on the bracket 70, one end of the pushing member 81 is propped against the wheel axle 71, the elastic member is positioned between the other end of the pushing member 81 and the baffle 74 on the bracket 70 and is propped against the pushing member 81 and the baffle 74, when the section sizes of the spring tube 50 and the hollow hose 30 become larger, pushing force is applied to the driven wheel 63, the driven wheel 63 drives the wheel axle 71 to slide so as to properly increase the gap size, the spring tube 50 and the hollow hose 30 are prevented from being compressed and deformed, and meanwhile, the wheel axle 71 stores elastic potential energy through the pushing member 81; when the sectional dimensions of the spring tube 50 and the hollow hose 30 become smaller, the elastic member releases elastic potential energy, and the wheel axle 71 is pushed to slide by the pushing member 81, so that the gap size is properly reduced, and slipping caused by loose engagement of the spring tube 50 with the driving wheel 62 is avoided. Thus, the elastic member cooperates with the pushing member 81, effectively ensuring floating adjustment of the gap.

Preferably, the number of the sliding holes 72 is two, the two sliding holes 72 are arranged in parallel, and the driven wheel 63 is positioned between the two sliding holes 72, as shown in fig. 6, 8, 11 and 17; the pushing member 81 comprises a first plate 811, a second plate 812 and a third plate 813, the first plate 811, the second plate 812 and the third plate 813 are connected in sequence such that the pushing member 81 is in a U shape, and free ends of the first plate 811 and the third plate 813 abut against the wheel axle 71, as shown in fig. 11, 13, 15 and 17.

The two ends of the wheel axle 71 are inserted into the two slide holes 72, and the driven wheel 63 is positioned between the two slide holes 72, so that the stress balance of the wheel axle 71 is ensured, and further, the stable rotation of the driven wheel 63 is ensured; the pushing member 81 is U-shaped, and two free ends of the U-shape (i.e. the free ends of the first plate 811 and the third plate 813) are abutted against the axle 71, so that the axle 71 is ensured to be stressed uniformly during sliding, and the balance between the axle 71 and the driven wheel 63 is further maintained.

Further, the free ends of the first plate 811 and the third plate 813 are provided with a clamping groove 814, and the axle 71 is clamped into the clamping groove 814, as shown in fig. 9.

The free ends of the first plate 811 and the third plate 813 are provided with the clamping groove 814, and the wheel axle 71 is clamped into the clamping groove 814, so that the clamping groove 814 plays a certain limiting role on the wheel axle 71, the probability that the wheel axle 71 is separated from the pushing piece 81 can be reduced, and the matching stability of the wheel axle 71 and the pushing piece 81 is improved.

Preferably, the axle 71 is circumferentially provided with an annular groove 711, and the free ends of the first plate 811 and the third plate 813 are embedded in the annular groove 711, as shown in fig. 9.

The wheel axle 71 is provided with an annular groove 711 along the circumferential direction, the free ends of the first plate 811 and the third plate 813 are embedded into the annular groove 711, and the annular groove 711 also plays a certain limiting role on the pushing piece 81, so that the probability that the pushing piece 81 is separated from the wheel axle 71 can be reduced, and the matching stability of the wheel axle 71 and the pushing piece 81 is further improved.

Further, two sliding grooves 73 are further formed on the support 70, as shown in fig. 8, and sliding blocks 815 are further formed at the lower ends of the first plate 811 and the third plate 813, and as shown in fig. 9, the sliding blocks 815 are embedded in the sliding grooves 73 and can slide along the sliding grooves 73.

The support 70 is further provided with two sliding grooves 73, the lower ends of the first plate 811 and the third plate 813 are further provided with sliding blocks 815 matched with the sliding grooves 73, so that the sliding blocks 815 and the sliding grooves 73 are matched with each other to play a role in positioning the pushing piece 81, so that the pushing piece 81 can be conveniently and rapidly mounted on the support 70, meanwhile, the sliding of the pushing piece 81 is guided, the situation that the pushing piece 81 is deviated or inclined in the moving process is avoided, and the use reliability of the floating limiting assembly 80 is further improved.

Preferably, the first plate 811 and the third plate 813 are located outside the two slide holes 72, and the openings of the two slide grooves 73 are disposed opposite to each other, as shown in fig. 8.

The first plate 811 and the third plate 813 are located at the outer sides of the two sliding holes 72, and the openings of the two sliding grooves 73 are arranged opposite to each other (i.e. facing away from each other), so that the pushing member 81 is clamped at two sides of the bracket 70, which not only limits the movement of the pushing member 81 along the direction perpendicular to the axle 71, but also limits the movement of the pushing member 81 along the direction parallel to the axle 71, and simultaneously, the two sliding blocks 815 need to move in opposite directions to separate from the bracket 70, thereby improving the stability of the matching between the pushing member 81 and the bracket 70, reducing the probability that the pushing member 81 separates from the bracket 70 or is inclined in an offset manner, and the like, and further improving the reliability of the use of the floating limiting assembly 80.

Of course, the openings of the two sliding grooves 73 may be oriented in other directions, for example, the openings are all upward, so that the pushing member 81 is installed from top to bottom, and it is convenient for the sliding block 815 to be directly inserted into the sliding groove 73, which is not limited to the above-mentioned opposite arrangement or the openings are all upward, which are not listed here. The above embodiments can achieve the object of the present invention without departing from the spirit and scope of the present invention, and therefore all the embodiments are within the scope of the present invention.

Further, the third plate 813 is provided with a first limiting post 816, as shown in fig. 9, the baffle 74 is provided with a second limiting post 741, as shown in fig. 8, the elastic member is a spring 82, and two ends of the spring 82 are respectively sleeved on the first limiting post 816 and the second limiting post 741, as shown in fig. 11, 13, 15 and 17.

The elastic piece is a spring 82, the spring 82 has good elasticity, the materials are easy to obtain, and the price is low; the arrangement of the first limiting column 816 and the second limiting column 741 plays a better limiting role on the spring 82, and ensures effective matching of the spring 82 with the pushing member 81 and the baffle 74.

The working principle is basically the same as that of the first embodiment, but during the working process, the two ends of the axle 71 can slide in the slide holes 72; the wheel axle 71 clamps the two ends through the clamping positions (namely clamping grooves 814) of the push plate (namely the pushing piece 81), so that the wheel axle 71 is stressed consistently and balanced when sliding; the push plate is connected with the upper cover 10 (namely, the bracket 70 on the upper cover 10 can be integrally formed with the upper cover 10) by a spring 82, and the driven wheel 63 is always pressed by the spring 82 force to form an assembly of the hollow hose 30 and the spring tube 50; the elasticity of the spring 82 ensures that the driven wheel 63 presses the assembly formed by the hollow hose 30 and the spring tube 50, and also ensures that the hollow hose 30 and the spring tube 50 are not deformed, so that the assembly formed by the hollow hose 30 and the spring tube 50 can be more effectively meshed with the driving wheel 62, and does not slip during relative movement, and effective energy transfer is ensured.

In any of the above embodiments, the cooking appliance further comprises: a drum 90 is mounted on the upper cover 10 through a rotation shaft 91, and a portion of the hollow hose 30 and the spring tube 50 is wound around the drum 90 as shown in fig. 1, 2, 3, 4, 5, 6, 10 and 12.

The roller 90 is arranged on the upper cover 10, and a part of the hollow hose 30 and the spring tube 50 is wound on the roller 90, so that the lengths of the hollow hose 30 and the spring tube 50 can be prolonged, and the complicated pipeline or the excessively large volume of the upper cover 10 caused by the increase of the lengths of the hollow hose 30 and the spring tube 50 can be avoided; and the hollow hose 30 and the spring 82 are sleeved on the roller 90, so that a better limiting effect is achieved on the parts of the hollow hose 30 and the spring tube 50 on the upper cover 10, and the probability of shaking and swaying in the movement process of the hollow hose 30 and the spring tube 50 can be reduced.

Preferably, the rotation shaft 91 extends in a horizontal direction as shown in fig. 1, 2, 3, 4, 5, 6, 10 and 12.

Since the spring tube 50 and the hollow hose 30 are necessarily horizontally extended in a tangential direction to the drum 90, when the rotation shaft 91 is extended in a horizontal direction, the hollow hose 30 and the spring tube 50 can be extended from the upper end of the drum 90, so that the parts of the spring tube 50 and the hollow hose 30 on the upper cover 10 are always maintained at a relatively fixed height, friction between the spring tube 50 and the upper cover 10 during movement can be avoided, and smooth extension and retraction movements of the spring tube 50 and the hollow hose 30 can be facilitated.
