Description

Technical Field

[0001] The utility model relates to the technical field of cooking, in particular to a cooking device. Background Art

[0002] There is a cooking device that can adjust its cooking pressure during the cooking process, so that ingredients can be cooked under negative pressure or micro-pressure conditions, thereby improving the cooking effect. Negative pressure cooking can increase the shelf life of ingredients and the retention time of flavor, and has a preservation effect. Micro-pressure cooking can increase the degree of gelatinization of ingredients (such as rice) under high temperature conditions. However, if the pressure inside and outside the cooking cavity cannot be balanced in time at the end of negative pressure cooking, the lid of the cooking device will not be able to be opened; when the pressure in the cooking cavity is too high during micro-pressure cooking, if the pressure cannot be released in time, there will be a risk of damage to the structural parts of the cooking device.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0051] In some embodiments, a cooking device, such as an electric rice cooker, is provided, which can achieve pressure cooking, vacuum cooking, etc.

[0052] Reference Figure 1 The cooking device comprises a pot body 10 and a pot cover 20. A cooking cavity is formed in the pot body 10, and the pot cover 20 is rotatably connected to the pot body 10, and the pot cover 20 is used to close or open the cooking cavity.

[0053] During pressure cooking, the pressure inside the cooking chamber is greater than the external atmospheric pressure. Pressure cooking can increase the gelatinization degree of ingredients (such as rice) under high temperature conditions and improve the taste.

[0054] During pressure cooking, when the pressure in the cooking cavity is too high, the cooking cavity needs to be depressurized in time, otherwise it is easy to cause damage to the internal structural parts. After the pressure cooking is finished, the cooking cavity needs to be depressurized before the pot cover 20 can be opened.

[0055] During vacuum cooking, the pressure in the cooking chamber is less than atmospheric pressure. Vacuum cooking uses negative pressure to increase the shelf life of ingredients and the retention time of flavor, thus achieving a freshness-preserving effect.

[0056] After vacuum cooking, the pot cover 20 can be opened only after the internal and external pressures of the cooking cavity are balanced.

[0057] The cooking device is provided with a pressure relief mechanism on the pot cover 20 to balance the internal and external pressures of the cooking cavity, so that the pot cover 20 can be opened smoothly after pressure cooking or vacuum cooking.

[0058] Reference Figures 2 to 4 , a pressure relief port 23 is provided on the pot cover 20. After the pot cover 20 is buckled, the pressure relief port 23 is connected to the cooking cavity. The pressure relief mechanism opens the pressure relief port 23, and the cooking cavity is connected to the outside atmosphere through the pressure relief port 23 to balance the internal and external pressures of the cooking cavity. When the pot cover 20 needs to be opened, the pressure relief mechanism opens the pressure relief port 23 before the pot cover 20 is opened.

[0059] The pressure relief mechanism includes a lifting assembly 100, which is disposed in the pot cover 20. When the lifting assembly 100 moves toward the direction close to the pressure relief port 23, the lifting assembly 100 closes the pressure relief port 23. When the lifting assembly 100 moves away from the pressure relief port 23, the lifting assembly 100 opens the pressure relief port 23.

[0060] The driving assembly 200 is used to drive the lifting assembly 100 to move. The driving components include a driving motor 210, a cam 220, and a driving transmission part 230. The cam 220 is connected to the power shaft of the driving motor 210, and the driving motor 210 drives the cam 220 to rotate. The driving transmission part 230 is arranged between the cam 220 and the lifting assembly 100, and the driving transmission part 230 is used to transmit the force of the cam 220 to the lifting assembly 100. The driving transmission part 230 is actuated by the cam 220 to drive the lifting assembly 100 to move in a direction away from the pressure relief port 23.

[0061] After pressure cooking or vacuum cooking is completed, when the pressure inside and outside the cooking cavity is balanced before opening the pot cover 20, the driving motor 210 drives the cam 220 to rotate, and the cam 220 abuts against one end of the driving transmission part 230 to Figure 4 Taking the shown position as an example, the cam 220 drives one end of the driving transmission part 230 to move downward, and the other end of the driving transmission part 230 moves upward, driving the lifting assembly 100 to move upward, and the lifting assembly 100 moves away from the pressure relief port 23. The pressure relief port 23 is opened, and the cooking cavity is connected to the outside atmosphere to balance the internal and external pressures.

[0062] The present application utilizes a driving assembly 200 composed of a driving motor 210, a cam 220, and a driving transmission part 230 to drive the upward movement of the lifting assembly 100, which can simultaneously meet the requirements of opening the lid for pressure cooking and vacuum cooking. The technical problem that the prior art electromagnet drive switch solution is difficult to meet the requirements of opening the lid for pressure cooking and vacuum cooking due to the small thrust of the electromagnet is solved.

[0063] The present invention solves the technical problem that the electromagnet driving scheme in the prior art needs to be powered on continuously to keep the cover open, generates a lot of heat for a long time and affects the service life.

[0064] In some embodiments, the drive transmission part 230 is a plate-shaped or rod-shaped structure with a certain length, and the middle part of the drive transmission part is rotatably connected to the pot cover 20 through the rotating shaft 280. After one end of the drive transmission part 230 is subjected to force, it can rotate with the rotating shaft 280 as a fulcrum. For example, when the cam 220 is pressed downward against one end of the drive transmission part 230, the other end of the drive transmission part 230 is tilted upward.

[0065] In some embodiments, the lifting assembly 100 includes a reset member 130 . When the lifting assembly 100 is driven by the driving assembly 200 to move in a direction away from the pressure relief port 23 , the reset member 130 accumulates elastic energy.

[0066] When the driving assembly 200 releases the force acting on the lifting assembly 100 , the restoring member 130 is reset to drive the lifting assembly 100 to move toward the direction close to the pressure relief port 23 .

[0067] Specifically, the reset member 130 is a spring. When the lifting assembly 100 moves in a direction away from the pressure relief port 23, that is, when the lifting assembly 100 moves upward, the spring is forced to contract. When the lifting assembly 100 is not acted upon by the driving assembly 200, the spring is reset, and the reset force of the spring drives the lifting assembly 100 to move in a direction close to the pressure relief port 23, that is, the lifting assembly 100 moves downward.

[0068] In some embodiments, reference Figure 4 The lifting assembly 100 includes a guide rod 110 , a flexible telescopic portion 120 and a reset member 130 .

[0069] A flexible telescopic portion 120 is provided at one end of the guide rod 110, and the other end is connected to the drive transmission portion 230. One end of the flexible telescopic portion 120 is fixedly disposed in the pot cover 20, and the other end is used to close the pressure relief port 23. The reset member 130 is used to apply a force to the guide rod 110 to move the guide rod 110 toward the pressure relief port 23, so that the flexible telescopic portion 120 closes the pressure relief port 23.

[0070] Specifically, the guide rod 110 extends up and down along the height direction of the pot cover 20 , a flexible telescopic portion 120 is provided at the lower end of the guide rod 110 , and an upper end of the guide rod 110 is fixedly connected to the drive transmission portion 230 .

[0071] The flexible telescopic part 120 is made of silicone material, and can be stretched or contracted when subjected to force. The upper end of the flexible telescopic part 120 is fixed in the pot cover 20, and the lower end can move downward under the action of the guide rod 110, that is, when the guide rod 110 moves downward, the guide rod 110 drives the flexible telescopic part 120 to move downward synchronously, and the flexible telescopic part 120 is stretched under force until the flexible telescopic part 120 abuts against the pressure relief port 23, thereby closing the pressure relief port 23.

[0072] In some embodiments, the flexible telescopic portion 120 is sleeved on one end of the guide rod 110 , the spring is sleeved on the guide rod 110 , and the spring is located in a gap between the flexible telescopic portion 120 and the guide rod 110 .

[0073] The spring is built-in, and the gap between the flexible telescopic part 120 and the guide rod 110 is fully utilized, and the structure is compact.

[0074] In some embodiments, the guide rod 110 includes a guide rod section 111 and a guide rod section 112 of an integrated structure, one end of the guide rod section 111 is connected to the drive transmission part 230, and the other end is connected to the guide rod section 112, and the diameter of the guide rod section 112 is greater than the diameter of the guide rod section 111. The guide rod section 111 is a rod-shaped structure, and the guide rod section 112 is a flat plate-shaped structure.

[0075] The flexible telescopic portion 120 includes a telescopic portion section 121 and a telescopic portion section 2 122. The telescopic portion section 121 is sleeved on the guide rod section 111, and the telescopic portion section 2 122 wraps the guide rod section 2 112. A cavity structure with one end open is formed in the flexible telescopic portion 120. The circumferential wall of the telescopic portion section 121 is a bellows-like structure so that it can be extended or contracted. The telescopic portion section 2 122 wraps the guide rod section 2 112, and when the guide rod 110 moves toward the direction close to the pressure relief port 23, the telescopic portion section 2 can better close the pressure relief port 23.

[0076] When the guide rod 110 moves in a direction away from the pressure relief port 23 , since one end of the flexible telescopic portion 120 is fixed, the first telescopic portion 121 is telescoped under the action of the guide rod 110 , and the second telescopic portion 122 is away from the pressure relief port 23 .

[0077] When the guide rod 110 is not acted upon by the driving transmission part 230 , the reset member 130 rebounds, and the reset member 130 drives the guide rod 110 to move toward the pressure relief port 23 , the telescopic part section 121 extends, and the telescopic part section 22 closes the pressure relief port 23 .

[0078] In some embodiments, the pot cover 20 includes an inner cover 21 and an inner lining 22, and the inner cover 21 is provided with a pressure relief port 23. The flexible telescopic portion 120 is fixedly arranged on the inner lining 22, and the flexible telescopic portion 120 performs telescopic movement in the space between the inner cover 21 and the inner lining 22.

[0079] The installation of the flexible telescopic portion 120 fully utilizes the existing structural components and space in the pot cover 20, is easy to install, and has a compact structure.

[0080] In some embodiments, a limiting portion 300 is provided on the side of the lining 22 facing away from the inner cover 21 , and the limiting portion 300 limits and fixes one end of the flexible telescopic portion 120 to the lining 22 . A through hole is provided in the limiting portion 300 , and the guide rod 110 passes through the through hole.

[0081] The installation reliability of the flexible telescopic portion 120 is improved by the limiting portion 300. At the same time, the up and down movement of the guide rod 110 in the through hole in the limiting portion 300 also plays a role in movement guidance.

[0082] In some embodiments, a mounting groove 24 is provided on the lining 22 , a folded edge 123 is provided at one end of the flexible telescopic portion 120 , and the folded edge 123 is disposed in the mounting groove 24 to achieve fixed installation of the flexible telescopic portion 120 on the lining 22 .

[0083] The position limiting portion 300 is mounted on the inner lining 22 by means of fasteners such as screws. The position limiting portion 300 is provided with a first extending portion 310 and a second extending portion 320 on a side facing the inner lining 22.

[0084] The first extension portion 310 abuts against the folded edge 123 to limit the folded edge 123 into the installation groove 24 , further improving the installation reliability of the flexible telescopic portion 120 .

[0085] The second extension portion 320 extends into the gap between the flexible telescopic portion 120 and the guide rod 110 to abut against one end of the spring. The spring is located between the second extension portion 320 and the second section 112 of the guide rod.

[0086] When the telescopic section 121 is extended or contracted, the second extension portion 320 extends into the gap between the flexible telescopic section 120 and the guide rod 110, thereby preventing the open end of the flexible telescopic section 120 from being deformed and reducing the connection reliability between the flexible telescopic section 120 and the lining 22.

[0087] In some embodiments, a mounting seat 270 is provided on the side of the lining 22 facing away from the inner cover 21 , and the drive transmission part 230 is rotatably connected to the mounting seat 270 via a rotating shaft 280 , one end of the drive transmission part 230 is fixedly connected to the guide rod 110 , and the other end is located below the cam 220 .

[0088] A screw 250 and a washer 260 are disposed at one end of the guide rod 110 , and one end of the drive transmission portion 230 is located between the washer 260 and the limiting portion 300 .

[0089] In some embodiments, the end of the cam 220 that is used to abut against the drive transmission part 230 is a contact end 221. The contact end 221 is a large end of the cam 220.

[0090] A motor base 240 is disposed in the pot cover 20, the motor is disposed on the motor base 240, and a first limiting portion 241 and a second limiting portion 242 are disposed on the motor base 240. Figure 3 Taking the position facing the driving motor 210 as an example, the first limiting portion 241 is disposed at an upper position on the left side of the cam 220 , and the second limiting portion 242 is disposed on the right side of the cam 220 .

[0091] The first limiting portion 241 is used to limit the rotation angle of the contact end 221 along the first direction away from the drive transmission portion 230. The second limiting portion 242 is used to limit the rotation angle of the contact end 221 along the second direction away from the drive transmission portion 230.

[0092] Specifically, taking the position facing the driving motor 210 as an example, when the cooking cavity needs to balance the internal and external pressures, the driving motor 210 drives the cam 220 to rotate clockwise, and the contact end 221 of the cam 220 moves toward the direction close to the first limiting portion 241, until the cam 220 contacts the first limiting portion 241, and the driving motor 210 completes the positioning; then the driving motor 210 drives the cam 220 to rotate counterclockwise, until the contact end 221 of the cam 220 abuts against the driving transmission portion 230, with the continuous rotation of the cam 220, one end of the driving transmission portion 230 is pressed downward, until the cam 220 contacts the second limiting portion 242 to stop, and the other end of the driving transmission portion 230 is tilted upward, driving the guide rod 110 to move upward synchronously, so that the flexible telescopic portion 120 moves upward, and the pressure relief port 23 is opened.

[0093] When the cooking cavity needs to be sealed, the driving motor 210 drives the cam 220 to release the first limit portion 241, the cam 220 does not apply force to the drive transmission portion 230, the reset member 130 rebounds, the drive guide rod 110 moves downward, and the flexible telescopic portion 120 squeezes the pressure relief port 23 to achieve sealing of the cooking cavity.

[0094] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.
