[0032] In order to make the purpose, technical solutions and advantages of the present application more clear, the following will further describe the present application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0033] There are various kinds of cooking utensils, including electric rice cookers, pressure cookers, electric stew pots, etc. Taking the pressure cooker as an example, the pressure cooker uses steam pressure to speed up the cooking process through sealing. The working principle of the pressure cooker is to seal the air in the pot, so that the steam cannot escape, thereby generating higher pressure in the pot than the atmospheric pressure. This increased pressure can increase the boiling point of water, so that the food is cooked at a higher temperature, thereby shortening the cooking time, and also maintaining the nutritional ingredients and flavor of the food.

[0034] And no matter is open fire uses the cooking utensil or the electric heating cooking utensil, its use safety is the most for the user to use the relation. The stress process of the cooking utensil in the use process is as follows, the cooking utensil is heated, makes the water evaporate, the pressure generated in the cooking cavity will gradually rise, so that the pot cover and the pot tooth of the outer pot generate the larger pressure between each other, this needs the pot tooth to have the stronger strength to satisfy the safe use requirement of the cooking utensil.

[0035] However, in the related art, the strength of the pot tooth is increased by increasing the thickness of the pot tooth, so as to satisfy the safe use requirement of the cooking utensil, which increases the weight of the outer pot and the amount of raw materials, thereby increasing the production cost of the cooking utensil.

[0036] Based on this, the embodiment of the present application provides an outer pot and a cooking utensil, aiming at improving the problem of high cost of the cooking utensil in the related art.

[0037] Please refer to Figures 1 to 2 , the present application also provides a cooking utensil, which comprises the above-mentioned outer pot 1, inner pot and pot cover, the outer pot 1 comprises a pot body 11 and a plurality of pot teeth 12, the pot body 11 is formed with a slot 1111 upward accommodation groove 111, the shape of the pot body 11 has many kinds, the pot body 11 can be cylindrical, the pot body 11 can also be square, preferably, the pot body 11 is cylindrical, the cylindrical shape makes the stress of the pot body 11 uniform, and the phenomenon of local stress collapse is not easy to occur. The pot body 11 can be made of metal material, plastic material or other materials, which is not limited here.

[0038] The pot tooth 12 is connected with the pot body 11, the plurality of pot teeth 12 are arranged along the circumferential direction of the pot body 11, the pot tooth 12 is arranged at the slot 1111 of the accommodation groove 111 and protrudes outward of the pot body 11, the shape of the pot tooth 12 has many kinds, the pot tooth 12 can be semicircular, square or other shapes, which is not limited here.

[0039] Please refer to Figures 1 to 2 , the outer pot 1 further comprises a reinforcing portion 13, one part of the reinforcing portion 13 is formed on the pot tooth 12, and the other part of the reinforcing portion 13 is formed on the pot body 11, it can be understood that the two ends of the reinforcing portion 13 are located on the pot tooth 12 and the pot body 11 respectively, so that the reinforcing portion 13 is located on the side of the pot tooth 12 close to the pot body 11, the reinforcing portion 13 can be located on the inner side of the pot body 11 or the outer side of the pot body 11, which is not limited here. Preferably, the reinforcing portion 13 is arranged on the radial inner side of the pot tooth 12, which can further improve the strength and structural stability of the pot tooth 12.

[0040] The shape of the reinforcing portion 13 is various, for example, the bottom surface of the reinforcing portion 13 can be arc-shaped, inclined surface 131, or stepped surface, which is not limited here.

[0041] The inner pot is arranged in the accommodating groove, and the inner pot has a processing groove for placing food materials. The inner pot is the part of the cooking utensil that directly contacts the food, and is usually made of materials with good heat conductivity, such as aluminum alloy or stainless steel. The inner pot can be mounted in the accommodating groove 111, or can be placed in the accommodating groove 111. Preferably, the inner pot is placed in the accommodating groove 111, which is convenient for the user to take out the inner pot for cleaning.

[0042] The pot cover is arranged on the slot opening 1111 of the accommodating groove 111, and is used to be locked with the pot teeth 12 and to be sealed with the inner pot to form a cooking cavity. It can be understood that the cooking cavity is formed by the processing groove and the pot cover. The pot cover is arranged on the slot opening 1111 of the accommodating groove 111, and is used to be sealed with the pot teeth 12 and the inner pot. The pot cover can be rotatably mounted on the outer pot 1, or can be detachably connected with the outer pot 1, which is not limited here.

[0043] The cooking utensil further comprises a heating assembly for heating the cooking cavity to process the food materials in the cooking cavity. The heating assembly can be arranged on the bottom of the accommodating groove 111, or can be arranged on the pot cover, which is not limited here.

[0044] After the pot cover is arranged on the slot opening 1111 of the accommodating groove 111 and the pot cover is locked with the pot teeth 12, the heating assembly can heat the cooking cavity to heat the food materials in the cooking cavity. The heating of the cooking cavity gradually increases the internal pressure of the cooking cavity, and acts on the pot cover and the inner pot to gradually increase the pressure between the pot cover and the pot teeth 12.

[0045] The cooking utensil further comprises a sealing ring arranged on the pot cover. After the pot cover is arranged on the slot opening 1111 of the accommodating groove 111 and the pot cover is locked with the pot teeth 12, the sealing ring is arranged around the pot opening of the inner pot and is extruded by the pot cover and the inner pot to seal the gap between the pot cover and the inner pot. This can improve the sealing performance of the cooking cavity, thereby improving the working efficiency of the pressure cooker.

[0046] The cooking utensil further comprises a housing cover wrapped around the outer periphery of the pot body 11. The housing cover usually serves as the outer structure of the cooking utensil, and plays a role in protecting the internal electronic components and the heating system, i.e. providing a solid housing to protect the internal structure from external impact and damage, and the housing cover also helps to maintain the overall appearance of the cooking utensil. The housing cover is usually made of durable and insulating materials, such as plastic, metal or metal-plastic composite materials.

[0047] The cooking utensil further comprises a lock catch assembly responsible for controlling locking and unlocking between the pot cover and the shell cover, ensuring that the pot cover can be safely opened and closed, preventing the pot cover from being accidentally opened due to steam pressure or other external forces, thereby protecting the user from scalding or steam burns.

[0048] The pot cover comprises an inner cover and an outer cover, the inner cover is rotationally installed on the surface of the outer cover facing the pot body 11, and the outer cover is connected with the shell cover through the lock catch assembly. When the cooking utensil is used, the outer cover is first covered on the pot body 11, and then the lock catch assembly is driven to lock the shell cover and the outer cover, and then the inner cover is driven to rotate to cooperate with the pot teeth 12 to lock the inner cover and the pot body 11. When the cooking utensil is opened, the inner cover is first driven to rotate to disengage with the pot teeth 12, and then the lock catch assembly is driven to disengage the locking between the shell cover and the outer cover, and finally the outer cover is opened

[0049] During use of the cooking utensil, as the temperature in the cooking cavity gradually increases, the pressure in the cooking cavity gradually increases, so that the force between the pot cover and the pot teeth 12 gradually increases, and part of the force is shared by the pot body 11 through the reinforcing portion 13, so that the pot teeth 12 can withstand greater force. In the related art, the position of the pot teeth 12 is a plane, in order to ensure that the pot teeth 12 do not deform after being stressed, the wall thickness of the material can only be increased to 1.2 mm. The pot body 11 of the present application enhances the strength of the pot teeth 12 by setting the reinforcing portion 13, so that the same shape of the pot teeth 12 with a thickness of 1.2 mm can be achieved using a material with a thickness of 0.9 mm. The pot teeth 12 are fixed and supported, and then the bottom of the pot body 11 receives a downward force, at which time the stress is transmitted to the pot teeth 12, and the reinforcing portion 13 increases the strength of the pot teeth 12, so that compared with the pot teeth 12 before modification, the same thickness has a greater pressure.

[0050] The outer pot 1 in the embodiment of the present application improves the strength of the pot teeth 12 by setting the reinforcing portion 13, and the two ends of the reinforcing portion 13 are located on the pot body 11 and the pot teeth 12 respectively, so that the pot body 11 can share part of the pressure of the pot teeth 12, thereby effectively solving the problem of pot explosion caused by insufficient strength of the pot teeth 12, and at the same time, thinner material can be used to manufacture the outer pot 1, so that the outer pot 1 has moderate thickness and light weight, and the use amount of raw materials of the outer pot 1 is reduced, thereby reducing the production cost of the outer pot 1.

[0051] Please refer to Figure 1The number of the reinforcing portions 13 can be one, a part of the pot teeth 12, or all of the pot teeth 12, or a plurality of the pot teeth 12. Preferably, at least one reinforcing portion 13 is formed on each of the pot teeth 12 to improve the strength of each of the pot teeth 12 and effectively solve the problem of the pot explosion caused by the insufficient strength of the pot teeth 12. It should be noted that each of the pot teeth 12 can have only one reinforcing portion 13 or a plurality of reinforcing portions 13.

[0052] Referring to Figure 3 The reinforcing portion 13 has a dimension h in the height direction, where h≥10 mm. It can be understood that the greater the h, the greater the overlapping area of the reinforcing portion 13 and the pot body 11 in the radial direction of the pot body 11, so that the strength of the pot teeth 12 can be improved.

[0053] Considering that the force trajectory of the pot teeth needs to be directed towards the inside of the pot body 11 to enable the cooking appliance to normally cook, if the direction is directed towards the outside of the pot body 11, the service life of the pot teeth 12 will be affected due to the small area of the pot teeth 12. Therefore, the reinforcing portion 13 needs to guide the entire force to extend towards the center of the cooking appliance with a larger area. In view of this, referring to Figure 3 The reinforcing portion 13 is a groove-shaped structure formed by the upper surface of the pot tooth 12 and the inner wall surface of the accommodating groove 111. The groove bottom wall of the groove-shaped structure is a slope 131, and the angle between the slope 131 and the upper surface of the pot tooth 12 is α, where 45°≤α≤80°. In this way, the slope 131 is inclined in the upward direction towards the inside of the pot body 11, forming a reinforcing trajectory in the same direction as the force direction of the pot tooth 12, thereby improving the service life of the pot tooth 12.

[0054] It should be noted that since the groove-shaped structure is formed by the upper surface of the pot tooth 12 and the inner wall surface of the accommodating groove 111, the groove opening 1111 is directed towards the inside of the pot body 11. The shape of the groove-shaped structure can be cylindrical, square, or other shapes, as long as the groove bottom wall is a slope 131. Preferably, the groove-shaped structure is square, and the connection between the inner wall surface of the groove-shaped structure and the upper surface of the pot tooth 12 and the inner wall surface of the accommodating groove 111 is an arc surface, which facilitates the processing of the reinforcing portion 13 and improves the strength of the reinforcing portion 13. It can be understood that the reinforcing portion 13 is a groove-shaped structure, and the reinforcing portion 13 can be a groove formed by the upper surface of the pot tooth 12 and the inner wall surface of the pot body 11. At this time, the lower surface of the pot and the outer peripheral wall of the pot body 11 form a pressing rib.

[0055] Please refer to Figure 4 In some embodiments of the present application, the pot teeth 12 have two connecting sections 121 and a supporting section 122 between the two connecting sections 121 in the circumferential direction of the pot body 11, the distance between the connecting section 121 and the central axis of the pot body 11 gradually increases in the direction that the connecting section 121 is close to the supporting section 122, and the supporting section 122 is provided with a reinforcing portion 13. In this way, the molding of the pot teeth 12 can be facilitated, and the phenomenon of stress concentration between the pot teeth 12 and the pot body 11 can be avoided.

[0056] Preferably, please refer to Figure 4 The connecting section 121 and the supporting section 122 can be smoothly transitioned, so that the phenomenon of stress concentration between the connecting section 121 and the supporting section 122 can be avoided. Similarly, the connecting section 121 and the pot body 11 can also be smoothly transitioned, so that the phenomenon of stress concentration between the connecting section 121 and the pot body 11 can be avoided.

[0057] Specifically, please refer to Figure 4 The number of reinforcing portions 13 on the same pot tooth 12 is one or at least two are arranged at intervals, the distance between the two ends of the supporting section 122 in the circumferential direction of the pot tooth 12 is a, the distance between the two connecting sections 121 on the same pot tooth 12 close to one end of the accommodating groove 111 in the circumferential direction of the pot tooth 12 is b, and the sum of the distances between the two ends of the reinforcing portion 13 on the same pot tooth 12 in the circumferential direction of the pot tooth 12 is c, wherein a / 2

[0058] It should be noted that, please refer to Figure 5 When the number of reinforcing portions 13 on the same pot tooth 12 is one, the distance between the two ends of the reinforcing portion 13 in the circumferential direction of the pot tooth 12 is c; please refer to Figure 5 When the number of reinforcing portions 13 on the same pot tooth 12 is two, the distance between the two ends of one reinforcing portion 13 in the circumferential direction of the pot tooth 12 is c1, the distance between the two ends of the other reinforcing portion 13 in the circumferential direction of the pot tooth 12 is c2, and c = c1 + c2, which will not be listed one by one.

In this way, by connecting the pot body 112 and the pot teeth 12 through the ring-shaped flange 113, the strength of the connection between the pot teeth 12 and the pot body 11 can be strengthened, thereby improving the strength of the pot teeth 12, and at the same time, the phenomenon of stress concentration between the pot teeth 12 and the pot body 112 can be avoided. The outer pot 1 can be formed by casting, and the outer pot 1 can also be formed by stamping. At this time, the ring-shaped flange 113 and the pot teeth 12 can be folded on the upper end of the pot body 112.

[0060] It should be noted that the reinforcing portion 13 is divided into a front section, a middle section and a rear section in the direction from the outside to the inside, the front section is located on the pot teeth 12, the middle section is located on the ring-shaped flange 113, and the rear section is located on the pot body 112.
