Description

Technical Field

[0001] The present application belongs to the technical field of kitchen appliances, and in particular relates to a pressure cooking device. Background Art

[0002] A pressure cooking device is a common kitchen appliance, which includes a pot body and a pot cover. The pot body includes an outer shell, a heat-insulating cover arranged in the outer shell, and an inner pot arranged in the heat-insulating cover. A sealing ring is provided on the periphery of the pot cover so that the pot cover and the inner pot form a sealed cooking cavity together.

[0003] Because the pressure cooking appliance relies on the thermal expansion of the sealing ring to achieve sealing during the pressure sealing stage, during the heating process, the sealing ring gradually becomes larger due to the heat, and sufficient space is required to achieve fit with the inner pot and the lid. In this process, the sealing ring needs to self-correct and seal, so sufficient clearance needs to be left between the lid and the inner pot. In addition, there are tolerances in the production process of accessories, and too small a clearance will affect the closing experience of the lid, resulting in poor opening and closing of the lid, which requires a larger clearance between the lid and the insulation cover.

[0004] However, a larger fitting gap will cause a larger amount of shaking between the pot lid and the pot body, resulting in a circumferential step difference between the pot lid and the pot body, affecting the user experience. Utility Model Content

[0014] Alternatively, the midline divides the pot cover into a front area and a rear area respectively located on both sides of the midline, and the limiting protrusion is located in the rear area.

[0015] The water collecting trough is provided with a guide groove extending along the circumference of the pot body, and the pot cover is provided with a guide rib whose width is adapted to the groove width of the guide groove. During the screwing process of the pot cover and the pot body, the guide rib slides into the guide groove.

[0020] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0021] 1. The pressure cooking device in the present application comprises a pot body and a pot cover which can be placed on the pot body, the pot cover is rotatably engaged with the pot body, a water collecting groove is arranged along the circumference of the rim of the pot body, the water collecting groove comprises a collecting section and a connecting section whose groove width is smaller than the collecting section, and the pot cover is provided with a limiting rib, when the pot cover is rotatably engaged with the pot body, the limiting rib moves from the collecting section to the connecting section and cooperates with the connecting section in a limiting manner, it can be understood that when closing the pot cover, the pot cover is first placed on the top of the pot body, and at the same time, the pot cover is misaligned with the pot body in the circumferential direction so that the limiting rib is located in the collecting section, and then the pot cover is rotated, and then the pot cover drives the limiting rib to move, the limiting rib moves from the collecting section to the connecting section and cooperates with the connecting section in a limiting manner, so that the limiting cooperation between the limiting rib and the connecting section reduces the shaking amount of the pot cover and the pot body, thereby reducing the circumferential section difference between the pot cover and the pot body, improving the product quality of the pressure cooking device, and further improving the user experience. At the same time, when the pot lid is closed, the limiting rib moves from the collecting section to the connecting section, and when the pot lid is opened, the limiting rib moves from the connecting section to the collecting section. Since the groove width of the collecting section is greater than the groove width of the connecting section, the smoothness of opening and closing the pot lid is ensured, further improving the user experience.

[0022] 2. As a preferred embodiment of the present application, the pot body is provided with a blocking rib extending into the water collecting tank, and the pot cover is provided with a limiting protrusion. After the pot cover is screwed together with the pot body, the blocking rib cooperates with the limiting protrusion stop. It can be understood that when the pot cover is rotated to make the pot cover and the pot body rotate and engage, the pot cover drives the limiting protrusion to rotate, and then makes the limiting protrusion move from the collecting section toward the connecting section. When the limiting rib moves to the connecting section, the limiting protrusion abuts against the blocking rib, so that the limiting protrusion cooperates with the blocking rib stop to limit the continued rotation of the pot cover, thereby achieving the effect of facilitating the rotation and engagement of the pot cover with the pot body. On the one hand, it prevents the pot cover from rotating excessively and causing the limiting rib and the connecting section to get stuck, thereby achieving the effect of facilitating the opening of the pot cover. On the other hand, the cooperation position of the limiting rib and the connecting section is in a set position to ensure that the shaking amount of the pot cover and the pot body is kept at a small state, so as to reduce the step difference between the pot cover and the pot body in the circumferential direction, thereby further improving the user experience. In addition, the cooperation between the limiting protrusion and the blocking rib can also reduce the amount of shaking between the pot cover and the pot body, so as to further reduce the step difference between the pot cover and the pot body in the circumference, further increase the appearance quality of the pressure cooking appliance, and improve the user experience.

[0023] 3. As a preferred embodiment of the present application, a stop bevel is provided on one side of the blocking rib facing the limiting protrusion, and the limiting protrusion is provided with a matching bevel that cooperates with the stop bevel, so that after the limiting rib moves to the set position of the connecting section, the matching bevel abuts against the stop bevel, and then the pot cover cannot continue to rotate, so as to achieve the effect of limiting the pot cover. At the same time, the stop bevel can also increase the gap between the side of the limiting protrusion and the outer groove wall of the connecting section when the limiting protrusion cooperates with the blocking rib, so as to prevent the limiting protrusion and the outer groove wall of the connecting section from getting stuck, so as to ensure the smoothness of opening and closing the pot cover, and further achieve the effect of facilitating the opening and closing of the pot cover. In addition, the stop bevel can also increase the angle between the blocking rib and the groove wall of the water collection tank, so as to achieve the effect of facilitating the user to wipe the water collection tank, avoid the existence of sanitary dead corners, improve the cleanliness of the pressure cooking appliance, and further improve the user's experience.

[0024] 4. As a preferred embodiment of the present application, a guide groove extending along the circumference of the pot body is provided in the water collection tank, and a guide rib whose width matches the groove width of the guide groove is provided in the pot cover. During the process of the pot cover and the pot body being screwed together, the guide rib slides into the guide groove, and then the guide rib and the groove wall of the guide groove are limitedly matched, thereby limiting the pot cover, so as to further reduce the shaking amount between the pot cover and the pot body, further reduce the step difference between the pot cover and the pot body in the circumferential direction, further improve the appearance quality of the pressure cooking device, and further improve the user experience. At the same time, during the process of rotating the pot cover, the guide rib slides into the guide groove, and can also guide the rotation of the pot cover, so that the user can accurately rotate the pot cover to the right position, thereby achieving the effect of facilitating the user to close the pot cover, and further improving the user experience.

[0025] 5. As a preferred embodiment of the present application, the guide groove includes a limiting section that cooperates with the guide rib and a guide section located at one end of the limiting section toward the direction of the pot cover screwing, and the groove width of the guide section gradually decreases along the direction of the pot cover screwing, so that when the pot cover rotates toward the screwing direction, the guide rib first slides into the guide section, and then slides into the limiting section under the guidance of the groove wall of the guide section, so that the groove wall of the limiting section cooperates with the guide rib to achieve further limiting of the pot cover, and at the same time, it is convenient for the user to accurately rotate the pot cover into place, and improves the smoothness of the user when closing the cover. In addition, the setting of the guide section can also have a visual reminder effect on the user, so that the user can clearly understand the direction of screwing the pot cover, further improving the user's experience. In addition, the setting of the guide section can also increase the structural strength of the limiting section. On the one hand, it can increase the limiting stability of the limiting section on the guide rib and ensure the limiting effect of the limiting section on the pot cover. On the other hand, it can also increase the service life of the cooking utensil to further improve the user's experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Reference Figures 1 to 15 A pressure cooking device comprises a pot body 1 and a pot cover 2 which is removably placed on the pot body 1, the pot cover 2 is rotatably engaged with the pot body 1 (hereinafter referred to as "rotational engagement" for expansion), a water collecting groove 11 is arranged along the circumference of the mouth edge of the pot body 1, the water collecting groove 11 comprises a collecting section 111 and a connecting section 112 whose groove width is smaller than that of the collecting section 111, the pot cover 2 is provided with a limiting rib 21, when the pot cover 2 is screwed together with the pot body 1, the limiting rib 21 moves from the collecting section 111 to the connecting section 112 and is limitedly engaged with the connecting section 112.

[0050] When closing the pot cover 2, first place the pot cover 2 on the top of the pot body 1, and at the same time make the pot cover 2 offset from the pot body 1 in the circumferential direction so that the limiting rib 21 is located in the collecting section 111, and then rotate the pot cover 2, thereby making the pot cover 2 drive the limiting rib 21 to move, and the limiting rib 21 moves from the collecting section 111 to the connecting section 112 and cooperates with the connecting section 112, so that the limiting cooperation between the limiting rib 21 and the connecting section 112 reduces the shaking amount of the pot cover 2 and the pot body 1, thereby reducing the circumferential section difference between the pot cover 2 and the pot body 1, improving the product quality of the pressure cooking appliance, and further improving the user experience. At the same time, when the pot cover 2 is closed, the limiting rib 21 moves from the collecting section 111 to the connecting section 112, and when the pot cover 2 is opened, the limiting rib 21 moves from the connecting section 112 to the collecting section 111. Since the groove width of the collecting section 111 is greater than the groove width of the connecting section 112, the smoothness of opening and closing the pot cover 2 is ensured, further improving the user experience.

[0051] It should be noted that the limiting rib 21 in the present application cooperates with the existing water collecting trough 11 on the pot body 1, avoiding the need to provide a separate component on the pot cover 1, so that the pot body 1 can be produced using the existing mold, reducing the production cost of the pressure cooking appliance, while improving the appearance quality of the pot body 1, so as to further enhance the user experience.

[0052] The present application does not specifically limit the location of the limiting rib 21, and it can adopt any one of the following implementations:

[0053] Embodiment 1: In this embodiment, the pot cover 2 has left and right sides that are relatively arranged and a median line passing through the left and right sides and the center of the pot cover 2, and the limiting rib 21 is located on the median line.

[0054] Since the pressure cooking appliance is generally in the shape of a runway circle, and the short sides of the pressure cooking appliance are arranged parallel to the left and right sides of the pot cover 2, and the inner pot is generally in the shape of a circle, the groove width of the connecting section 112 at the corresponding midline is narrower than the groove width at other positions, so that the limiting rib 21 and the connecting section 112 are located at the position where the groove width of the connecting section 112 is the narrowest after limiting cooperation, thereby further reducing the shaking amount of the pot cover 2 and the pot body 1, so as to further reduce the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, further improving the appearance quality of the pressure cooking appliance, and improving the user experience.

[0055] Implementation method 2. In this implementation method, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The pot cover 2 has relatively arranged left and right sides and a median line passing through the left and right sides and the center of the pot cover 2. The median line divides the pot cover 2 into a front area and a rear area located on both sides of the median line. The limiting rib 21 is located in the connecting section 112 of the front area.

[0056] Specifically, after the pot cover 2 is screwed together with the pot body 1, the limiting rib 21 is located at the connecting section 112 corresponding to the front area, so that the groove width of the limiting rib 21 and the connecting section 112 at the limiting matching position is wider than the groove width at the corresponding midline position of the connecting section 112, so as to further increase the smoothness of opening and closing the pot cover 2, thereby further achieving the effect of facilitating the opening and closing of the pot cover 2.

[0057] In a preferred embodiment, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 The extension direction of the limiting rib 21 is set parallel to the direction of the median line, so that the limiting rib 21 is subjected to a force parallel to the direction of the median line when it cooperates with the connecting section 112, avoiding the situation where it generates force components in other directions, thereby ensuring the stability of the limiting cooperation between the limiting rib 21 and the connecting section 112, and further ensuring the appearance quality of the pressure cooking appliance and the user experience.

[0058] In a preferred embodiment, referring to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The pot body 1 is provided with a blocking rib 12 extending into the water collecting tank 11, and the pot cover 2 is provided with a limiting protrusion 22. After the pot cover 2 is screwed together with the pot body 1, the blocking rib 12 and the limiting protrusion 22 are stopped and matched.

[0059] When the pot cover 2 is rotated to screw the pot cover 2 with the pot body 1, the pot cover 2 drives the limiting protrusion 22 to rotate, and then the limiting protrusion 22 moves from the collecting section 111 to the connecting section 112. When the limiting rib 21 moves to the connecting section 112, the limiting protrusion 22 contacts the blocking rib 12, so that the limiting protrusion 22 cooperates with the blocking rib 12 to limit the continued rotation of the pot cover 2, thereby achieving the effect of facilitating the screwing of the pot cover 2. On the one hand, it prevents the pot cover 2 from rotating excessively and causing the limiting rib 21 and the connecting section 112 to get stuck, thereby achieving the effect of facilitating the opening of the pot cover 2. On the other hand, the matching position of the limiting rib 21 and the connecting section 112 is in a set position to ensure that the shaking amount of the pot cover 2 and the pot body 1 is kept at a small state, so as to reduce the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, thereby further improving the user experience. In addition, the cooperation between the limiting protrusion 22 and the blocking rib 12 can also reduce the shaking amount between the pot cover 2 and the pot body 1, so as to further reduce the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, further increase the appearance quality of the pressure cooking appliance, and improve the user experience.

[0060] In a preferred embodiment, referring to Figure 4 , Figure 5 , Figure 6 and Figure 7 A stop slope 121 is provided on one side of the blocking rib 12 facing the limiting protrusion 22 , and the limiting protrusion 22 is provided with a matching slope 221 that stops and cooperates with the stop slope 121 .

[0061] After the limiting rib 21 moves to the set position of the connecting section 112, the matching inclined surface 221 contacts the stopping inclined surface 121, and then the pot cover 2 cannot continue to rotate, so as to achieve the effect of limiting the pot cover 2. At the same time, the stopping inclined surface 121 can also increase the gap between the side of the limiting protrusion 22 and the outer groove wall of the connecting section 112 when the limiting protrusion 22 cooperates with the blocking protrusion 12, so as to prevent the limiting protrusion 22 from getting stuck with the outer groove wall of the connecting section 112, so as to ensure the smoothness of opening and closing the pot cover 2, and further achieve the effect of facilitating the opening and closing of the pot cover 2. In addition, the stopping inclined surface 121 can also increase the angle between the blocking protrusion 12 and the groove wall of the water collecting tank 11, so as to achieve the effect of facilitating the user to wipe the water collecting tank 11, avoid the existence of sanitary dead corners, improve the cleanliness of the pressure cooking device, and further improve the user's experience.

[0062] The present application does not specifically limit the position of the limiting protrusion 22, and it can adopt any one of the following embodiments:

[0063] Embodiment 1, in this embodiment, the pot cover 2 has left and right sides that are relatively arranged and a median line passing through the left and right sides and the center of the pot cover 2, and the limiting protrusion 22 is located on the median line.

[0064] Since the pressure cooking appliance is generally in the shape of a runway circle, and the short sides of the pressure cooking appliance are arranged parallel to the left and right sides of the pot cover 2, and the inner pot is generally circular, the groove width of the connecting section 112 at the corresponding midline is narrower than the groove width at other positions, so that the limiting protrusion 22 and the blocking rib 12 are located at the narrowest position of the groove width of the connecting section 112 after limiting cooperation, thereby further reducing the shaking amount of the pot cover 2 and the pot body 1, so as to further reduce the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, further improve the appearance quality of the pressure cooking appliance, and further improve the user experience.

[0065] Embodiment 2, in this embodiment, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The midline divides the pot cover 2 into a front area and a rear area located on both sides of the midline, and the limiting protrusion 22 is located in the rear area, so that the groove width of the limiting protrusion 22 and the blocking rib 12 at the limiting matching position is wider than the groove width at the connecting section 112 corresponding to the midline position, so as to further increase the smoothness of opening and closing the pot cover 2, thereby further achieving the effect of facilitating the user to open and close the pot cover 2.

[0066] In a preferred embodiment, referring to Figure 7 , Figure 8 , Fig. 9 , Fig.14 and Fig.15 A guide groove 13 extending along the circumference of the pot body 1 is provided in the water collecting trough 11, and a guide rib 23 whose width is adapted to the groove width of the guide groove 13 is provided in the pot cover 2. During the screwing process of the pot cover 2 and the pot body 1, the guide rib 23 slides into the guide groove 13.

[0067] Specifically, after the pot cover 2 is screwed together with the pot body 1, the guide rib 23 slides into the guide groove 13, and then the guide rib 23 is limited and matched with the groove wall of the guide groove 13, so as to limit the pot cover 2, so as to further reduce the shaking amount between the pot cover 2 and the pot body 1, further reduce the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, further improve the appearance quality of the pressure cooking device, and further improve the user's experience. At the same time, in the process of rotating the pot cover 2, the guide rib 23 slides into the guide groove 13, and can also guide the rotation of the pot cover 2, so that the user can accurately rotate the pot cover 2 to the right position, thereby achieving the effect of facilitating the user to close the pot cover 2, and further improving the user's experience.

[0068] The present application does not specifically limit the structure of the guide groove 13, and the guide groove 13 may adopt any one of the following embodiments:

[0069] Embodiment 1, in this embodiment, refer to Figure 7 , Figure 8 and Fig. 9 A first guide rib 113 and a second guide rib 114 extending along the circumference of the pot body 1 are provided in the water collecting tank 11, and the second guide rib 114 is located on the outer side of the first guide rib 113, and a guide groove 13 is formed between the first guide rib 113 and the second guide rib 114, that is, the guide groove 13 is formed by ribs higher than the bottom of the water collecting tank 11, so that the first guide rib 113 and the second guide rib 114 can serve as a visual reminder to the user, thereby facilitating the user to correctly screw the pot cover 2 into place, improving the efficiency of the user in closing the pot cover 2, and further improving the user's experience.

[0070] The present application does not specifically limit the formation method of the first guide rib 113 and the second guide rib 114. Preferably, the first guide rib 113 and the second guide rib 114 are formed by protruding upward from the bottom of the water collecting trough 11, that is, the first guide rib 113 and the second guide rib 114 are an integral structure with the bottom of the water collecting trough 11 to increase the structural strength of the first guide rib 113 and the second guide rib 114, thereby ensuring the limiting stability of the guide convex rib 23. In other implementation examples, the first guide rib 113 and the second guide rib 114 can also be a separate structure from the bottom of the water collecting trough 11, that is, the first guide rib 113 and the second guide rib 114 are separate components, both of which are fixedly connected to the bottom of the water collecting trough 11 by additional fixings.

[0071] Embodiment 2: In this embodiment, the guide groove 13 is formed by a partial area of ​​the water collecting groove 11 being recessed downward to ensure the structural strength of the groove wall of the guide groove 13 and increase the matching stability between the guide groove 13 and the guide rib 23 .

[0072] The present application does not specifically limit the structure of the guide groove 13. Preferably, refer to Figure 7 , Figure 8 and Fig. 9 The guide groove 13 includes a limiting section 131 that cooperates with the guiding rib 23 and a guiding section 132 located at one end of the limiting section 131 facing the screwing direction of the pot cover 2, and the groove width of the guiding section 132 gradually decreases along the screwing direction of the pot cover 2.

[0073] When the pot cover 2 rotates toward the screwing direction, the guide rib 23 first slides into the guide section 132, and then slides into the limiting section 131 under the guidance of the groove wall of the guide section 132, so that the groove wall of the limiting section 131 and the guide rib 23 are limited to cooperate to achieve further limiting of the pot cover 2, and at the same time, it is convenient for the user to accurately rotate the pot cover 2 into place, and improve the smoothness of the user when closing the cover. In addition, the setting of the guide section 132 can also serve as a visual reminder to the user, so that the user can clearly understand the direction of screwing the pot cover 2, further improving the user's experience. In addition, the setting of the guide section 132 can also increase the structural strength of the limiting section 131. On the one hand, it can increase the limiting stability of the limiting section 131 on the guide rib 23, ensure the limiting effect of the limiting section 131 on the pot cover 2, and on the other hand, it can also increase the service life of the cooking utensil, so as to further improve the user's experience.

[0074] In other embodiments, the width of the guide groove 13 may be set to remain unchanged along the screwing direction of the pot cover 2 .

[0075] In a preferred embodiment, referring to Figure 4 , Figure 5 , Figure 6 and Figure 7 The pot body 1 has a left and right end that are relatively arranged, and the connecting section 112 is located at the left and right ends of the pot body 1. The pot cover 2 has a left and right side that are relatively arranged with the left and right ends, and a front and rear side located on both sides of the left and right sides. The pot cover 2 has a central axis passing through the front and rear sides and the center of the pot cover 2. The guide rib 23 passes through the central axis, and then the limiting rib 21 and the connecting section 112 are matched to limit the pot cover 2 in the direction parallel to the left and right sides of the pot cover 2. The limiting rib 23 and the guide groove 13 are matched to limit the pot cover 2 in the direction of the central axis, so as to further reduce the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, improve the appearance quality of the pressure cooking device, and further improve the user experience.

[0076] In a preferred embodiment, the pressure cooking appliance further comprises a micro switch arranged inside the pot body 1, the micro switch is arranged corresponding to the guide groove 13 and has a transmission end extending from the guide groove 13, so that when the pot cover 2 is screwed on, the guide rib 23 applies pressure to the transmission end, and then the transmission end triggers the micro switch, thereby enabling the pressure cooking appliance to perform cooking operations.

[0077] Preferably, the guide rib 23 has a pressure end for applying pressure to the transmission end and a limiting end opposite to the pressure section, and the pressure end is provided with a guide surface 231 so that the thickness of the pressure end gradually increases in the direction approaching the limiting end, so that when the pot cover 2 is screwed on, the guide surface 231 contacts and guides the transmission end, thereby causing the transmission end to move downward and trigger the micro switch, so as to further increase the smoothness of closing the pot cover 2 and further improve the user experience.

[0078] In a preferred embodiment, referring to Fig.11 and Fig.12 The pot body 1 has a water collecting rib 14, which surrounds the pot body 1 and constitutes the outer wall of the water collecting groove 11. The limiting rib 21 is limitedly matched with the side wall of the water collecting rib 14. The pot cover 2 has a limiting surface 24 located outside the limiting rib 21, and the limiting surface 24 is matched with the top wall stop of the water collecting rib 14.

[0079] Specifically, after the pot cover 2 is screwed together with the pot body 1, the limiting rib 21 cooperates with the side wall of the water-collecting rib 14, and then the limiting rib 21 cooperates with the side wall of the water-collecting rib 14 to reduce the shaking amount of the pot cover 2, so as to increase the step difference between the pot cover 2 and the pot body 1 in the circumferential direction, improve the appearance quality of the pressure cooking appliance, and further improve the user experience; the limiting surface 24 cooperates with the top wall stop of the water-collecting rib 14, so that the limiting surface 24 cooperates with the top wall stop of the water-collecting rib 14 to limit the pot cover 2 in the vertical direction, so as to increase the screwing stability of the pot cover 2 and the pot body 1, thereby ensuring the sealing of the cooking cavity and ensuring the cooking efficiency of the pressure cooking appliance.

[0080] It should be noted that the front, back, left and right mentioned in this application are all based on the normal placement of the pressure cooking device when in use. The front refers to the side facing the user, the back refers to the side away from the user, the left refers to the side close to the user's left hand side, and the right refers to the side close to the user's right hand side.
