Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to an installation structure of a driving device and a cooking utensil. Background Art

[0002] The electric rice cooker is a commonly used household appliance. During the cooking process, as the soaking time goes by and the water temperature rises, the surface of the rice grains begins to gelatinize and become sticky, and the rice grains will stick together to form a rice ball. Since the thermal conductivity of rice is much lower than that of water, the clumped rice grains will hinder the uniform transfer of heat to the rice in the steamer, causing the rice grains wrapped in the middle of the rice ball to be unable to absorb water and become half-cooked. In addition, the rice in the electric rice cooker is heated unevenly from top to bottom, so the gelatinization degree of the rice in different positions in the rice cooker is also inconsistent, causing some places to be over-gelatinized and rotten, while some places are not completely gelatinized, resulting in a large difference in the uniformity of the maturity of the whole pot of rice, affecting the taste of the rice.

[0003] In order to solve the problem of insufficient water absorption and insufficient gelatinization of rice grains, industry technicians have improved the rice cooker so that the rice cooker can achieve positive and negative pressure states in stages during the cooking process. Specifically, during the water absorption stage, a vacuum device is used to generate negative pressure in the pot to promote water absorption by rice grains. After boiling, the cooking cavity is sealed to generate positive pressure in the pot, so that the temperature in the pot is raised to above 100°C, promoting sufficient gelatinization of rice grains.

[0004] Since the electric rice cooker is in a positive pressure working state, the positive pressure inside the pot will exert an upward force on the cover plate, which is easy to push the cover plate open, resulting in changes in the pressure inside the pot, making it impossible for the electric rice cooker to maintain a positive pressure working environment. Therefore, the existing cover plate is provided with a reinforcement frame so that the cover plate can tightly cover the pot body. However, the reinforcement frame occupies a large space on the cover plate, which limits the installation of the drive device, and the drive device cannot accurately realize the opening and closing of the reflux hole and the air hole. Utility Model Content

[0005] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a mounting structure of a driving device, so that the driving device can accurately transmit on the cover plate to realize the opening and closing of the return hole and the air hole without affecting the strength of the cover plate.

[0017] Furthermore, the cover plate has two side plates extending upwards corresponding to the limiting rod, and the two side plates are arranged opposite to each other at intervals along the second direction to form a guide channel adapted to the limiting rod, and the limiting rod moves along the first direction through the guide channel.

[0018] Furthermore, blocking parts are extended toward each other on the top inner walls of the two side plates, and the limiting rod is arranged non-contactly below the blocking part, and the projection of the blocking part on the horizontal plane partially overlaps with the projection of the limiting rod on the horizontal plane.

[0032] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] The utility model provides a cooking utensil, which can be an electric rice cooker, a pressure cooker or the like, and can realize positive pressure, normal pressure or negative pressure operation. Figure 1 The cooking utensil comprises a cover plate 1, a pot body 7 and an inner pot 8. The inner pot 8 is arranged in the accommodating cavity of the pot body 7. The cover plate 1 is rotatably mounted on the pot body 7. A cooking cavity is formed between the cover plate 1 and the inner pot 8.

[0036] Since the cooking appliance is in a positive pressure working state, the positive pressure in the cooking cavity will exert an upward force on the cover plate 1, which is easy to push open the cover plate 1, resulting in changes in the pressure in the cooking cavity, making it impossible for the cooking appliance to maintain a positive pressure working environment. Therefore, it is very important to improve the strength of the cover plate 1 without affecting the precise control of the pressure in the cooking cavity.

[0037] To this end, the utility model provides an installation structure of a driving device, which includes a cover plate 1, a reflux assembly 2, a gravity ball 3, a reinforcement frame 4 and a driving device 5.

[0038] See also Figure 4 and Figure 5 The cover plate 1 is provided with a return hole 11 and an air hole 12 which penetrate vertically, and the line connecting the projection of the center of the return hole 11 along the vertical direction on the horizontal plane and the projection of the center of the air hole 12 along the vertical direction on the horizontal plane is not coincident or parallel to the projection of the first direction on the horizontal plane. Figure 4 For example, Figure 4 The middle left end is the front end of the cover plate 1. Figure 4 The middle right end is the rear end of the cover plate 1. Figure 4 The middle front end is the right end of the cover plate 1. Figure 4 The middle and rear end is the left end of the cover plate 1. On this basis, the first direction is the front-to-back direction, and the return hole 11 and the air hole 12 are not arranged front-to-back, but are arranged left-to-right or obliquely arranged front-to-back. In the present utility model, the return hole 11 is arranged at the left rear of the air hole 12.

[0039] See also Figure 3 and Figure 4 The reflux assembly 2 is disposed on the reflux hole 11 in a vertically movable manner to open or close the reflux hole 11. The gravity ball 3 is disposed on the air hole 12 in a horizontally movable manner along the first direction to open or close the air hole 12. Thus, the reflux assembly 2 is disposed at the left rear of the gravity ball 3.

[0040] See also Figure 3 and Figure 4 The reinforcing frame 4 is arranged on the cover plate 1 and extends along the first direction, that is, the reinforcing frame 4 is arranged front and back. The driving device 5 is arranged in the reinforcing frame 4 and extends along the first direction so as to be laterally movable along the first direction. The driving device 5 includes a first push rod 51 and a second push rod 52. The first push rod 51 is extended along the first direction corresponding to the reflux assembly 2. The first push rod 51 is connected to the top of the reflux assembly 2 to drive the reflux assembly 2 to move vertically when it moves laterally. The second push rod 52 is extended along the first direction corresponding to the gravity ball 3. The second push rod 52 is located on the side of the gravity ball 3 in the first direction to drive the gravity ball 3 to move laterally when it moves laterally.

[0041] The driving device 5 moves forward and backward along the first direction. When the driving device 5 moves forward, the second push rod 52 moves away from the gravity ball 3, and the gravity ball 3 closes the air hole 12. The first push rod 51 moves forward and pushes the reflux assembly 2 to move downward to close the reflux hole 11. At this time, the cooking cavity is a sealed environment. When the driving device 5 moves backward, the second push rod 52 pushes the gravity ball 3 to open the air hole 12, and the first push rod 51 moves backward and moves the reflux assembly 2 upward to open the reflux hole 11.

[0042] It should be noted that the structure and principle of the first push rod 51 driving the reflux assembly 2 to open and close the reflux hole 11 is prior art, which can be understood by referring to CN201520455798.9. The structure and principle of the second push rod 52 driving the gravity ball 3 to open and close the air hole 12 is prior art, which can be understood by referring to CN201520459662.5.

[0043] Therefore, the utility model arranges the driving device 5 to be located inside the reinforcing frame 4, and the extension direction of the driving device 5 is the same as the extension direction of the reinforcing frame 4, so that sufficient space is reserved on the cover plate 1 to install the driving device 5, and the volume, structure and travel path requirements of the driving device 5 are relatively low, thereby ensuring that the driving device 5 can be accurately transmitted on the cover plate 1 to realize the opening and closing of the return hole 11 and the air hole 12 without affecting the strength of the cover plate 1.

[0044] In addition, the utility model utilizes a driving device 5 to jointly drive the reflux component 2 and the gravity ball 3 to realize the opening and closing of the reflux hole 11 and the air hole 12, which not only ensures that the reflux hole 11 and the air hole 12 can be opened and closed synchronously, but also compared with two devices driving the reflux component 2 and the gravity ball 3 respectively, the driving device 5 has a simple structure and occupies less space.

[0045] See also Figure 3-5 The driving device 5 includes a driving body 53 that moves laterally along a first direction. The driving body 53 is arranged to extend along the first direction corresponding to the gravity ball 3. The second push rod 52 is connected to one end of the driving body 53 that faces the gravity ball 3. That is, the central axes of the driving body 53 and the second push rod 52 are on a straight line and are both arranged along the first direction. The second push rod 52 is connected to the rear end of the driving body 53.

[0046] The first push rod 51 includes a pushing section 511 extending along a first direction and a connecting section 512 extending along a second direction. The first direction and the second direction are on the same horizontal plane and are perpendicular to each other. One end of the connecting section 512 in the extending direction is connected to the side of the pushing body 53, and the other end of the connecting section 512 in the extending direction is connected to the end of the pushing section 511 away from the reflux component 2, so that the first push rod 51 is an L-shaped structure. That is, the second direction is the left-right direction, and the first push rod 51 is connected to the left side of the pushing body 53 and extends backward. The connecting section 512 is arranged left and right, the right end of the connecting section 512 is connected to the left side of the pushing body 53, and the left end of the connecting section 512 is connected to the front end of the pushing section 511. The pushing section 511 is arranged front and back, and the rear end of the pushing section 511 is connected to the top of the reflux component 2 so that when the pushing section 511 moves horizontally, the reflux component 2 is driven to move vertically.

[0047] The cover plate 1 is provided with a guide groove 13 extending along the first direction and adapted to the pushing body 53. The pushing body 53 is arranged in the guide groove 13 and moves laterally along the first direction. The setting of the guide groove 13 has the function of limiting and guiding the movement of the pushing body 53, avoiding the displacement of the moving direction of the pushing body 53, thereby ensuring the accuracy of the moving direction of the driving device 5.

[0048] The end of the pushing body 53 facing away from the second push rod 52 is provided with a limiting rod 54 extending in the first direction, that is, the limiting rod 54 is connected to the front end of the pushing body 53. The end of the cover plate 1 corresponding to the limiting rod 54 is rotatably connected with a locking structure 6. The locking hook of the locking structure 6 passes through the cover plate 1 and is hooked in the pot body 7. The locking structure 6 rotates clockwise to open the cover plate 1, and the locking structure 6 rotates counterclockwise to cover the cover plate 1 on the pot body 7. The locking structure 6 extends toward the limiting rod 54 to form a limiting plate 61. The limiting plate 61 is located above the cover plate 1 and is spaced from the cover plate 1 to form a limiting groove 62. When the driving device 5 moves toward the locking structure 6 along the first direction, the limiting rod 54 extends into the limiting groove 62, and the limiting rod 54 and the limiting plate 61 are arranged in a non-contact manner. When the driving device 5 moves along the first direction toward the locking structure 6, the reflux hole 11 and the air hole 12 are both in a closed state. At this time, the cooking cavity is a sealed working environment. Once the locking structure 6 tends to rotate clockwise due to accidental touch, the limiting rod 54 abuts against the limiting plate 61 to prevent the locking structure 6 from rotating clockwise and causing the cover to open, so as to ensure the safe operation of the cooking appliance.

[0049] The cover plate 1 has two side plates 14 extending upward corresponding to the limit rod 54. The two side plates 14 are arranged opposite to each other in a spaced relationship along the second direction to form a guide channel 15 adapted to the limit rod 54. The limit rod 54 moves along the first direction through the guide channel 15. The setting of the guide channel 15 has a guiding and limiting effect on the limit rod 54, preventing the limit rod 54 from deviating in its moving direction, thereby further ensuring the accuracy of the moving direction of the driving device 5.

[0050] The top inner walls of the two side plates 14 extend toward each other with blocking portions 141, and the limiting rod 54 is disposed below the blocking portion 141 without contact, and the projection of the blocking portion 141 on the horizontal plane partially overlaps with the projection of the limiting rod 54 on the horizontal plane. The blocking portion 141 vertically limits the limiting rod 54 to prevent the limiting rod 54 from tilting or escaping from the guide channel 15.

[0051] The driving device 5 further includes a driving assembly 55, and the movement of the pushing body 53, the first push rod 51, the second push rod 52 and the limiting rod 54 is realized by the driving assembly 55. The pushing body 53 is provided with a receiving groove 531 adapted to the driving assembly 55, and the driving assembly 55 is arranged in the receiving groove 531 and is in transmission connection with the pushing body 53, so as to drive the pushing body 53 to drive the first push rod 51, the second push rod 52 and the limiting rod 54 to move laterally along the first direction.

[0052] The driving assembly 55 includes an electromagnet and a spring, and the electromagnet is connected to the pushing body 53 through the spring. When the electromagnet is energized, the iron core of the electromagnet attracts the pushing body 53 to drive the first push rod 51, the second push rod 52 and the limit rod 54 to move forward along the first direction and compress the spring. The second push rod 52 does not apply force to the gravity ball 3, and the gravity ball 3 seals the air hole 12. The first push rod 51 pushes the reflux assembly 2 to move downward to seal the reflux hole 11. At this time, the cooking cavity is in a sealed working state, and the limit rod 54 is located in the limit groove 62, which can prevent the lock structure 6 from rotating clockwise and causing the cover to open, so as to ensure the safe operation of the cooking utensil. When the electromagnet is powered off, the iron core loses its suction force, and the elastic force of the spring drives the pushing body 53 to drive the first push rod 51, the second push rod 52 and the limit rod 54 to move backward along the first direction. The second push rod 52 pushes the gravity ball 3 to open the air hole 12, and the first push rod 51 does not apply force to the reflux assembly 2, and the reflux assembly 2 moves upward due to the rebound force to open the reflux hole 11. At this time, the limit rod 54 is located outside the limit groove 62, and the cover can be opened through the lock structure 6.

[0053] The reinforcement frame 4 includes two longitudinal beams 41 and a cross beam 42. The two longitudinal beams 41 extend along a first direction and are arranged at intervals and fixed on the cover plate 1. The cross beam 42 extends along a second direction. The first direction and the second direction are on the same horizontal plane and are perpendicular to each other. The cross beam 42 is connected between the two longitudinal beams 41. The cross beam 42 is non-contactly arranged below the driving device 5. That is, the two longitudinal beams 41 are arranged front and back and are respectively close to the left and right ends of the cover plate 1. The cross beam 42 is arranged left and right to connect the two longitudinal beams 41, thereby strengthening the strength of the cover plate 1 and preventing the positive pressure in the cooking cavity from pushing the cover plate 1 open.

[0054] Furthermore, the cross beam 42 is disposed below the driving device 5 in a non-contact manner, and the driving device 5 can limit the cross beam 42 in the vertical direction, thereby further improving the reinforcing function of the reinforcing frame 4 on the cover plate 1 .

[0055] The two longitudinal beams 41 are both structures with internal cavities and bottom openings. Support plates 16 are extended upward from the positions of the cover plate 1 corresponding to the two longitudinal beams 41. The length of the support plate 16 along the first direction matches the length of the corresponding longitudinal beam 41 along the first direction. The support plate 16 extends from the bottom opening of the longitudinal beam 41 to the internal cavity of the longitudinal beam 41 and abuts against the top inner wall of the longitudinal beam 41. The longitudinal beam 41 is a cavity structure, which can reduce the weight of the cooking utensil, and realizes the lightweight of the cooking utensil on the basis of improving the strength of the cover plate 1.

[0056] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
