[0029] See Figure 1 and Figure 2 The present application discloses a cooking appliance. The cooking appliance includes a pot body 1, an upper cover 2, a bubble breaking assembly 4, and a negative pressure assembly 5. In some embodiments, the upper cover 2 covers the pot body 1 to define a cooking cavity 3 with the pot body 1. Optionally, an inner pot may be provided in the pot body 1, and the upper cover 2 covers the inner pot so that the upper cover 2 and the inner pot form a cooking cavity 3. In some embodiments, the bubble breaking assembly 4 is rotatably connected to the side of the upper cover 2 away from the cooking cavity 3. The negative pressure assembly 5 includes a vacuum pump 51, a first exhaust pipe 52, and a second exhaust pipe 53. The air inlet of the vacuum pump 51 is connected to the cooking cavity 3 through the first exhaust pipe 52, and the air outlet of the vacuum pump 51 acts on the bubble breaking assembly 4 through the second exhaust pipe 53 to drive the bubble breaking assembly 4 to rotate. In this way, the vacuum pump 51 is driven to evacuate the cooking chamber 3 through the first exhaust pipe 52, and at the same time acts on the bubble breaking component 4 through the second exhaust pipe 53 to drive the bubble breaking component 4 to rotate, so that the rotation of the bubble breaking component 4 can intuitively reflect the changes in the working state of the vacuum pump 51, which is convenient for users to perceive and identify the changes in the working state of the vacuum pump 51, avoid users from misjudging that the cooking appliance has a fault, reduce users' troubles when using the cooking appliance, and improve users' usage experience.

[0030] See Figure 1 、 Figure 2 and Figure 4 In some embodiments, the negative pressure assembly 5 further includes a solenoid valve 6 disposed between the first exhaust pipe 52 and the cooking chamber 3. Thus, the solenoid valve 6 regulates the flow between the first exhaust pipe 52 and the cooking chamber 3, effectively preventing various external gases, particles, and even oil from entering the cooking chamber 3 through the second exhaust pipe 53, the vacuum pump 51, and the first exhaust pipe 52 when the vacuum pump 51 is powered off, thereby contaminating food and affecting food safety, hygiene, taste, and quality. Furthermore, the solenoid valve 6 can precisely control the flow between the first exhaust pipe 52 and the cooking chamber 3, thereby achieving precise control of internal parameters such as pressure and temperature in the rice cooker. This is particularly important for dishes that require a specific cooking environment.

[0031] See Figure 2 and Figure 3In some embodiments, the bubble breaking assembly 4 includes a bubble breaking shell 41, a rotating part 42 and a visual window 43. Optionally, the bubble breaking shell 41 is arranged on the side of the upper cover 2 away from the cooking cavity 3, and a accommodating cavity is provided in the bubble breaking shell 41. The second exhaust pipe 53 connects the air outlet of the vacuum pump 51 with the accommodating cavity; optionally, an assembly groove is provided on the side of the upper cover 2 away from the cooking cavity 3, and the bubble breaking shell 41 is fitted and connected to the assembly groove. Optionally, the bubble breaking shell 41 is provided on the upper cover 2, and the accommodating cavity is connected to the steam port of the upper cover 2. In this way, the steam generated by the food in the cooking cavity 3 during cooking enters the accommodating cavity through the steam port, so that the vacuum pump 51 and the upper cover 2 are both The accommodating cavity is exhausted, so that the exhaust structure of the vacuum pump 51 and the upper cover 2 are integrated on the bubble breaking component 4, without the need to add an additional exhaust structure, thereby optimizing the product structure. Therefore, when the vacuum pump 51 vacuums the cooking cavity 3 or the upper cover 2 is exhausted normally through the steam port, the bubble breaking component 4 exhausts the air to the outside, avoiding the user's misunderstanding that the product is leaking steam due to the presence of multiple exhaust structures in the cooking appliance, and causing trouble. At the same time, it can also better ensure the reliability of the product. The bubble breaking shell 41 and / or the transparent cover 44 can be provided with exhaust structures such as through holes, through grooves, exhaust valves, etc. that are connected to the accommodating cavity. The innovation of the present application does not lie in the specific exhaust method of the bubble breaking component 4, which will not be listed one by one here. Optionally, the rotating member 42 is rotatably connected to the accommodating chamber. Specifically, the rotating member 42 is disposed in the accommodating chamber and is capable of rotating relative to the bubble-breaking housing 41. When the vacuum pump 51 exhausts air into the accommodating chamber through the second exhaust pipe 53, the rotating member 42 is capable of rotating relative to the bubble-breaking housing 41 under the action of the airflow, so that the rotation of the rotating member 42 can intuitively reflect the change in the operating state of the vacuum pump 51, making it easier for a user to perceive and identify the change in the operating state of the vacuum pump 51. Optionally, the visual window 43 is provided in the bubble-breaking housing 41, and a transparent cover 44 is provided on the upper cover 2 of the visual window 43. Optionally, the visual window 43 can be provided at the upper end or side of the bubble-breaking housing 41. In this way, by providing the transparent cover 44 on the upper cover 2 of the visual window 43, external interference with the rotation of the rotating member 42 is prevented, and the user can observe the rotation of the rotating member 42 through the transparent cover 44.

[0032] See Figure 3 and Figure 4In some embodiments, the bubble breaking assembly 4 further includes an exhaust member 45, which is disposed outside the rotating member 42. The second exhaust pipe 53 connects the air outlet of the vacuum pump 51 with the exhaust member 45 to generate an airflow that drives the rotating member 42 to rotate. Preferably, the exhaust member 45 is disposed within the accommodating chamber and outside the rotating member 42. When the vacuum pump 51 is operating, the vacuum pump 51 extracts gas from the cooking chamber 3 through the first exhaust pipe 52 and delivers the gas to the exhaust member 45 through the second exhaust pipe 53. This allows the exhaust member 45 to generate an airflow within the accommodating chamber that drives the rotating member 42 to rotate, thereby driving the rotating member 42 to rotate.

[0033] See Figure 3 、 Figure 4 and Figure 5 In some embodiments, the upper cover 2 is provided with an exhaust connection portion 21, the lower end of the exhaust member 45 is cooperatively connected to the exhaust connection portion 21, and the lower end of the exhaust connection portion 21 is provided with an air pipe joint 22, and the second exhaust pipe 53 is connected to the air pipe joint 22. Optionally, the exhaust connection portion 21 is a groove or countersunk structure, and the lower end of the exhaust member 45 extends into the exhaust connection portion 21 to form a sealed fit. Preferably, the exhaust connection portion 21 is provided with an air hole connecting the exhaust connection portion 21 and the air pipe joint 22, so that the gas transported by the second exhaust pipe 53 passes through the air pipe joint 22 and the exhaust connection portion 21 in sequence and enters the exhaust member 45, thereby driving the exhaust member 45 to form an airflow in the accommodating chamber that drives the rotating member 42 to rotate, thereby driving the rotating member 42 to rotate.

[0034] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In some embodiments, the exhaust member 45 is provided with an exhaust slot 46, which is disposed opposite to the rotating member 42. Thus, the exhaust member 45 is provided with the exhaust slot 46, which is disposed opposite to the rotating member 42, so that the gas in the exhaust member 45 flows out from the exhaust slot 46, forming an airflow that drives the rotating member 42 to rotate, effectively driving the rotating member 42 to rotate. Optionally, the exhaust slot 46 is provided to extend in the height direction to increase the pressure of the airflow discharged from the exhaust slot 46. Optionally, the exhaust slot 46 can be replaced with a narrow slit structure provided in the height direction. Furthermore, the exhaust direction of the exhaust slot 46 is at a certain angle to the central axis of the rotating member 42, so that the airflow discharged from the exhaust slot 46 exerts an optimal force on the rotating member 42.

[0035] In some embodiments, the exhaust slot 46 has a horizontal width of less than or equal to 1 mm and a vertical length of 2 mm to 8 mm. That is, the exhaust slot 46 has a horizontal width of less than or equal to 1 mm and a vertical length of 2 mm to 8 mm. Since the exhaust slot 46 is a narrow and long slot, it can deliver a sufficiently high-pressure airflow to the rotating member 42, thereby ensuring that the vacuum pump 51 can effectively drive the rotating member 42 to rotate through the exhaust member 45 when in operation.

[0036] See Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In some embodiments, the exhaust direction of the exhaust slot 46 and the central axis of the rotating member 42 form an angle of 5°-45°. Figure 6 As shown, the exhaust direction of the exhaust slot 46 forms an angle A with the central axis of the rotating member 42, and the angle A is 5°-45°, so that the airflow discharged from the exhaust slot 46 can exert the best force on the rotating member 42, so that the airflow discharged from the exhaust slot 46 can more reliably drive the rotating member 42 to rotate.

[0037] See Figure 3 、 Figure 4 、 Figure 5 and Figure 7 In some embodiments, the rotating member 42 includes a swivel 421 having a plurality of blades 422 arranged around its circumference. A fulcrum 423 is provided at the upper end of the swivel 421, and the fulcrum 423 abuts against the bubble-breaking housing 41 or the transparent cover 44. Thus, when the vacuum pump 51 exhausts air into the accommodating chamber through the second exhaust pipe 53, the blades 422 can increase the contact area between the swivel 421 and the airflow discharged from the second exhaust pipe 53. At the same time, the fulcrum 423 abuts against the bubble-breaking housing 41 or the transparent cover 44, reducing the contact area between the swivel 421 and the bubble-breaking housing 41 or the transparent cover 44, thereby lowering friction and ensuring that the swivel 421 can rotate relative to the bubble-breaking housing 41 under the action of the airflow. This allows the rotation of the swivel 42 to intuitively reflect changes in the operating state of the vacuum pump 51, making it easier for a user to perceive and identify changes in the operating state of the vacuum pump 51.

[0038] See Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In some embodiments, the angle between the extension direction of the blade 422 and the radial direction of the rotor 421 is 20°-60°. Figure 7As shown, the extension direction of the blade 422 forms an angle B with the radial direction of the rotor 421, and the angle B is 20°-60°, so that the force of the airflow discharged from the second exhaust pipe 53 acting on the blade 422 is optimal, so as to reliably drive the rotor 421 to rotate.

[0039] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7In some embodiments, an inner pot may be provided in the pot body 1, and the upper cover 2 is covered on the inner pot so that the upper cover 2 and the inner pot form a cooking cavity 3, and the air inlet of the vacuum pump 51 is connected to the cooking cavity 3 through the first exhaust pipe 52, and the air outlet of the vacuum pump 51 acts on the bubble breaking component 4 through the second exhaust pipe 53. Optionally, the solenoid valve 6 is provided between the first exhaust pipe 52 and the cooking cavity 3. Preferably, the bubble breaking component 4 includes a bubble breaking shell 41, a rotating part 42, an exhaust part 45 and a visual window 43. Optionally, an assembly groove is provided on the side of the upper cover 2 away from the cooking cavity 3, and the bubble breaking shell 41 is matched and connected to In the assembly groove, optionally, the bubble breaking shell 41 is arranged on the upper cover 2, and the accommodating cavity is connected to the steam port of the upper cover 2, so that the steam generated by the food in the cooking cavity 3 during the cooking process enters the accommodating cavity through the steam port, so that the vacuum pump 51 and the upper cover 2 are both exhausted to the accommodating cavity, thereby realizing that the exhaust structure of the vacuum pump 51 and the upper cover 2 are integrated on the bubble breaking component 4, without the need to add an additional exhaust structure, thereby optimizing the product structure. Therefore, when the vacuum pump 51 evacuates the cooking cavity 3 or the upper cover 2 is normally exhausted through the steam port, the bubble breaking component 4 is exhausted to the outside to avoid The existence of multiple exhaust structures in the cooking appliance may cause users to misunderstand that the product is leaking steam and cause trouble. At the same time, it can also better ensure the reliability of the product. Optionally, the visual window 43 can be opened at the upper end or side of the bubble-breaking shell 41. In this way, by providing the transparent cover 44 on the visual window 43, the outside world is prevented from interfering with the rotation of the rotating member 42. At the same time, the user can observe the rotation of the rotating member 42 through the transparent cover 44. Preferably, the rotating member 42 includes a rotating body 421, and a plurality of blades 422 are arranged on the circumference of the rotating body 421. The upper end of the rotating body 421 is provided with a fulcrum portion 423, and the fulcrum portion 423 is connected to the bubble-breaking shell The blades 422 abut against the bubble-breaking shell 41 or the transparent cover 44. Optionally, the angle between the extension direction of the blades 422 and the radial direction of the rotator 421 is 20°-60°. In this way, when the vacuum pump 51 exhausts air into the accommodating chamber through the second exhaust pipe 53, the blades 422 can increase the contact area between the rotator 421 and the airflow discharged from the second exhaust pipe 53. At the same time, the fulcrum portion 423 abuts against the bubble-breaking shell 41 or the transparent cover 44, thereby reducing the contact area between the rotator 421 and the bubble-breaking shell 41 or the transparent cover 44, reducing friction, and ensuring that the rotator 421 can rotate relative to the bubble-breaking shell 41 under the action of the airflow.Optionally, the exhaust member 45 is arranged on the outside of the rotating member 42, and the second exhaust pipe 53 connects the air outlet of the vacuum pump 51 with the exhaust member 45 to form an airflow that drives the rotating member 42 to rotate. Optionally, the upper cover 2 is provided with an exhaust connection portion 21, and the lower end of the exhaust member 45 is cooperatively connected to the exhaust connection portion 21. The lower end of the exhaust connection portion 21 is provided with an air pipe joint 22, and the second exhaust pipe 53 is connected to the air pipe joint 22. Preferably, the exhaust member 45 is provided with an exhaust slot 46, and the horizontal width of the exhaust slot 46 is less than or equal to 1mm, the vertical length is 2mm-8mm, and the exhaust direction of the exhaust slot 46 is at an angle of 5°-45° to the central axis of the rotating member 42. When the vacuum pump 51 extracts gas from the cooking chamber 3 through the first exhaust pipe 52 and delivers gas to the exhaust member 45 through the second exhaust pipe 53, the exhaust member 45 delivers a sufficiently high-pressure airflow to the rotating member 42 through the exhaust slots 46. The airflow discharged from the exhaust slots 46 exerts maximum force on the blades 422, ensuring that the rotating body 421 can rotate relative to the bubble-breaking housing 41 under the action of the airflow. This allows the rotation of the rotating member 42 to intuitively reflect changes in the operating status of the vacuum pump 51, making it easier for the user to perceive and identify changes in the operating status of the vacuum pump 51, avoiding misjudgment of a malfunction in the cooking appliance, reducing user frustration when using the cooking appliance, and improving the user experience.
