Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils technology, and in particular to a cookware. Background Technology

[0002] During cooking, existing cookware may dry out as the liquid inside decreases, affecting its performance and potentially causing safety hazards. Utility Model Content

[0003] This application provides a cookware for reducing the safety risks caused by dry burning of the cookware during cooking.

[0004] The cookware provided in this application includes a pot body, a handle assembly, and a switch.

[0005] The pot body has a first receiving cavity, and the side wall of the pot body has a through hole;

[0006] The handle assembly is mounted on the pot body, and the handle assembly has a second receiving cavity;

[0007] The switch is installed on the pot body and can open or close the through hole. When the switch is open, the first accommodating cavity and the second accommodating cavity are connected through the through hole. When the switch is closed, the switch blocks the first accommodating cavity and the second accommodating cavity.

[0008] In this design, when the switch is open, the first and second receiving cavities are connected through a through hole, allowing liquid in the second cavity to enter the first cavity. This means that when the liquid level in the first cavity is too low, liquid from the handle assembly can enter the pot, reducing the risk of dry burning, improving the safety of the cookware, and minimizing performance degradation caused by dry burning. When the switch is closed, it seals the first and second receiving cavities, facilitating the heating of the liquid and food in the first cavity.

[0009] Optionally, the switching element is an elastic valve.

[0010] In this design, the elastic valve has high elasticity and flexibility, enabling it to adapt to complex hydraulic changes. This means it can work for a long time in environments with high-frequency bending and stretching while maintaining structural stability and good fatigue resistance. It can also effectively extend the service life of the cookware while ensuring that the switching components can be opened or closed smoothly.

[0011] Optionally, the switching element includes at least two diaphragms distributed circumferentially along the through hole. The diaphragms have a connecting end and a mating end. The connecting end is installed on the side wall of the pot body, and the mating end is located in the first receiving cavity.

[0012] In the open state, the mating ends are far apart to connect the first receiving cavity and the second receiving cavity; in the closed state, the mating ends abut against each other to block the first receiving cavity and the second receiving cavity.

[0013] In this design, the connecting end of the switch is detachably attached to the side wall of the pot, allowing users to easily disassemble the switch for cleaning and maintenance. The opening or closing of the switch is achieved by the mutual separation or contact of the mating ends, facilitating precise repair in case of switch failure and thus improving the stability of the switch's open or closed state.

[0014] Optionally, the cross-sectional area of ​​the diaphragm gradually decreases along the direction from the connecting end to the mating end.

[0015] In this design, the deformation of the mating end is greater than that of the connecting end, facilitating deformation of the mating end under the liquid pressure within the second receiving cavity, thereby enabling rapid opening or closing of the switch. Furthermore, a larger cross-sectional area at the connecting end increases the reliability of the connection between the switch and the pot body, reducing the risk of the switch detaching from the pot body.

[0016] Optionally, the center of the through hole is at a first distance L1 from the bottom wall of the pot body, and the height of the first receiving cavity is H, where 0.1×H≤L1≤0.2×H.

[0017] In this design, the first distance L1 between the center of the through hole and the bottom wall of the pot body satisfies 0.1×H≤L1≤0.2×H, meaning that the center height of the through hole is located at 10%-20% of the height of the pot body. The first distance L1 between the center of the through hole and the bottom wall of the pot body is moderate, and the distance between the switch and the bottom wall of the pot body is moderate. This improves the working efficiency of the switch while reducing material damage to the switch and extending its service life.

[0018] Optionally, the handle assembly includes a base and a movable member. The base is fixedly connected to the outer wall of the pot body, and the movable member is slidable relative to the base to open or close the second receiving cavity.

[0019] In this solution, the user can add liquid to the second cavity when it is open, and close the second cavity when the cookware is in cooking or storage mode to prevent foreign objects from entering and affecting the operation of the switch.

[0020] Optionally, the base includes a handle and a water storage portion. The handle extends radially outward relative to the water storage portion along the pot. The movable member is slidably connected to the handle. The second receiving cavity includes a first cavity and a second cavity. The handle and the outer wall of the pot form the first cavity, and the water storage portion and the outer wall of the pot form the second cavity.

[0021] In this design, a handle extending radially outward relative to the water storage section facilitates user gripping and movement of the cookware. The water storage section also allows for communication between the second and first cavities via a through-hole. The handle and water storage section provide both gripping functionality and ample water storage space, thus extending the user's reaction time in the event of the cookware drying out.

[0022] Optionally, the second cavity extends along the height direction of the cookware, and the second cavity has a first end that is away from the first cavity, and the cross-sectional area of ​​the first end gradually decreases along the direction away from the first cavity.

[0023] In this design, setting a first end reduces the risk of liquid accumulating in the second cavity, thus improving the cookware's anti-dry-burning effect.

[0024] Optionally, there is a second distance L2 between the bottom wall of the hand-held part and the bottom wall of the pot body, where 0.7×H≤L2≤0.8×H.

[0025] In this design, the second distance L2 between the bottom wall of the handle and the bottom wall of the pot body satisfies 0.7×H≤L2≤0.8×H, that is, the bottom height of the handle is located at 70%-80% of the height of the pot body. The second distance L2 between the bottom wall of the handle and the bottom wall of the pot body is moderate, which can improve the reliability of the handle, increase the water storage capacity of the first cavity, reduce the risk of user burns, and ensure that the switch can be opened normally.

[0026] Optionally, the handle assembly has a visible area extending along the height direction of the cookware, the visible area having a scale.

[0027] In this design, on the one hand, the user can add an appropriate amount of liquid to the second container through the visible area to ensure that the liquid level in the second container is between the highest and lowest levels, allowing the switch to open normally and preventing liquid from overflowing the second container. On the other hand, during the cooking process, the user can judge whether the pot has dried out by observing the changes in the liquid level in the visible area, increasing the user's reaction time and reducing the safety risks during the use of the pot.

[0065] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0066] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0067] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0068] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0069] This application provides a cookware, which can be a soup pot, steamer, stew pot, etc. This application does not limit the specific type of cookware. The following description uses a soup pot as an example.

[0070] like Figure 1 As shown, the cookware includes a pot body 1, a handle assembly 2, and a switch 3. The pot body 1 has a first receiving cavity 10, which can hold food to be cooked, and the side wall 12 of the pot body 1 has a through hole 11. The handle assembly 2 is mounted on the pot body 1, allowing the user to pick up the cookware. The handle assembly 2 has a second receiving cavity 20, which is used to hold liquid.

[0071] like Figures 2-5 As shown, the switch 3 is installed at the through hole 11 of the pot body 1. Specifically, the switch 3 is detachably connected to the pot body 1, and the switch 3 can be opened or closed. In a specific embodiment, when the switch 3 is opened, as... Figure 2 As shown, the first receiving cavity 10 and the second receiving cavity 20 are connected through a through hole 11. Liquid in the second receiving cavity 20 can enter the first receiving cavity 10. That is, when the liquid in the first receiving cavity 10 of the pot body 1 is too low, the liquid in the handle assembly 2 can enter the pot body 1, reducing the risk of dry burning of the pot body 1, improving the safety of the cookware, and reducing the performance degradation of the pot body 1 caused by dry burning. When the switch 3 is closed, as... Figure 3 As shown, the switch 3 blocks the first receiving cavity 10 and the second receiving cavity 20, thereby facilitating the heating of the liquid and food in the first receiving cavity 10.

[0072] like Figures 4-9 As shown, the specific structure of the switch 3 will be described below.

[0073] In some embodiments, the switch 3 is an elastic valve. The elastic valve can be opened by an external force, allowing liquid in the second receiving cavity 20 to enter the first receiving cavity 10, thereby reducing the risk of dry burning. The elastic valve can also automatically reset to the closed state, thereby isolating the first receiving cavity 10 and the second receiving cavity 20.

[0074] In this embodiment, the elastic valve has high elasticity and flexibility, and can adapt to complex hydraulic change environment. That is, it can work for a long time in the environment of high frequency bending and stretching, and can still maintain structural stability and have good fatigue resistance. Under the premise of ensuring that the switch 3 can be opened or closed smoothly, it can also effectively extend the service life of the cookware.

[0075] In one specific embodiment, the elastic valve can be made of food-grade silicone. Silicone elastic valves are easily removable and do not easily trap dirt, facilitating cleaning after cooking. In other embodiments, the elastic valve can be made of other elastic materials; this application does not limit the specific material of the elastic valve.

[0076] In some embodiments, such as Figures 6-9 As shown, the switch 3 includes at least two diaphragms 31 distributed circumferentially along the through hole 11. The diaphragm 31 has a connecting end 311 and a mating end 312. The connecting end 311 is installed on the side wall 12 of the pot body 1, and the mating end 312 is located in the first receiving cavity 10.

[0077] In this embodiment, the connecting end 311 of the switch 3 is detachably connected to the side wall 12 of the pot body 1, which facilitates easy disassembly of the switch 3 for cleaning and maintenance by the user. The mating end 312 of the switch 3 is located in the first receiving cavity 10 of the pot body 1, such as... Figure 4 and Figure 8 As shown. When the switch 3 is in the open state, the mating ends 312 are far apart, and the gap between the mating ends 312 connects the first receiving cavity 10 and the second receiving cavity 20, thereby reducing the risk of dry burning. In the closed state, as... Figure 5 and Figure 9 As shown, the mating ends 312 abut against each other to seal the first receiving cavity 10 and the second receiving cavity 20. That is, the opening or closing of the switch 3 is achieved by the mutual separation or mutual abutment of the mating ends 312, which is conducive to accurate maintenance in case of switch 3 failure, and thus improves the stability of the open or closed state of the switch 3.

[0078] In this embodiment, the opening or closing of the switch 3 is achieved through the hydraulic difference between the first receiving cavity 10 and the second receiving cavity 20. Since the mating end 312 of the switch 3 is located in the first receiving cavity 10, the elastic valve can deform within the first receiving cavity 10 to open or close the switch 3. Specifically, when the liquid pressure in the first receiving cavity 10 is lower than the liquid pressure in the second receiving cavity 20, the switch 3 will open under the action of the liquid pressure in the second receiving cavity 20. That is, the liquid pressure in the second receiving cavity 20 overcomes the liquid pressure in the first receiving cavity 10, pushing the mating ends 312 of each diaphragm 31 away from each other. The liquid in the second receiving cavity 20 will flow into the first receiving cavity 10 until the liquid pressure in the first receiving cavity 10 and the second receiving cavity 20 are balanced. At this time, under the action of the elastic valve's rebound force, the mating ends 312 of each diaphragm 31 will approach and abut against each other, causing the switch 3 to close. After cooking continues for a period of time, the liquid level in the first receiving cavity 10 gradually decreases, and a liquid pressure difference is generated at both ends of the switch 3. That is, the liquid pressure in the first receiving cavity 10 is once again less than the liquid pressure in the second receiving cavity 20. At this time, the switch 3 is opened again under the action of the liquid pressure in the second receiving cavity 20, and the liquid in the second receiving cavity 20 flows back into the first receiving cavity 10. This can prevent dry burning, delay the user's reaction time, and reduce the safety risks of the cookware.

[0079] In addition, since the mating end 312 of the diaphragm 31 is located in the first receiving cavity 10, the elastic valve cannot open when the liquid pressure in the first receiving cavity 10 is greater than the liquid pressure in the second receiving cavity 20. Therefore, the switch 3 can only be opened when the liquid pressure in the second receiving cavity 20 is greater than the liquid pressure in the first receiving cavity 10, so that the liquid in the second receiving cavity 20 can flow into the first receiving cavity 10. That is, the switch 3 can play a one-way conduction role and prevent the liquid in the first receiving cavity 10 from flowing into the second receiving cavity 20.

[0080] In some embodiments, such as Figure 5 As shown, the cross-sectional area of ​​the diaphragm 31 gradually decreases along the direction from the connecting end 311 to the mating end 312. Therefore, the deformation of the mating end 312 is greater than that of the connecting end 311, which facilitates the deformation of the mating end 312 under the action of the liquid pressure in the second receiving cavity 20, thereby quickly realizing the opening or closing of the switch 3. In addition, when the cross-sectional area of ​​the connecting end 311 is larger, the connection reliability between the switch 3 and the pot body 1 is higher, reducing the risk of the switch 3 detaching from the pot body 1.

[0081] In the above embodiments, such as Figure 2 and Figure 3As shown, there is a first distance L1 between the center of the through hole 11 and the bottom wall 13 of the pot body 1, and the height of the first receiving cavity 10 is H, 0.1×H≤L1≤0.2×H. For example, the first distance L1 between the center of the through hole 11 and the bottom wall 13 of the pot body 1 can be 0.1×H, 0.13×H, 0.15×H, 0.17×H, 0.2×H, etc.

[0082] In this embodiment, the distance between the center of the through hole 11 and the bottom wall 13 of the pot body 1 can represent the height of the through hole 11 and the switch 3 on the pot body 1. When the first distance L1 between the center of the through hole 11 and the bottom wall 13 of the pot body 1 is too small, the distance between the switch 3 and the bottom wall 13 of the pot body 1 is too close, and the switch 3 is too close to the heating source at the bottom of the pot body 1, causing the switch 3 to be in a high-temperature state for a long time, which can easily damage the silicone valve and affect the working efficiency of the switch. When the first distance L1 between the center of the through hole 11 and the bottom wall 13 of the pot body 1 is too large, the distance between the switch 3 and the bottom wall 13 of the pot body 1 is too far. When the center of the liquid level through hole 11 in the first receiving cavity 10, i.e., the switch 3, is above the liquid surface, the switch 3 cannot be opened, and the liquid in the second receiving cavity 20 cannot enter the first receiving cavity 10, so that the pot still has the risk of dry burning.

[0083] In this embodiment, the first distance L1 between the center of the through hole 11 and the bottom wall 13 of the pot body 1 satisfies 0.1×H≤L1≤0.2×H, that is, the center height of the through hole 11 is located at 10%-20% of the height of the pot body 1. The first distance L1 between the center of the through hole 11 and the bottom wall 13 of the pot body 1 is moderate, and the distance between the switch 3 and the bottom wall 13 of the pot body 1 is moderate. While improving the working efficiency of the switch 3, it reduces material damage to the switch 3 and improves the service life of the switch 3.

[0084] The specific structure of handle assembly 2 will be described below.

[0085] In some embodiments, such as Figure 1 and Figure 10 As shown, the handle assembly 2 includes a base 21 and a movable part 22. The base 21 is fixedly connected to the outer wall of the pot body 1, and the movable part 22 can move relative to the base 21 to open or close the second receiving cavity 20.

[0086] In this embodiment, the movable member 22 can move relative to the base 21, so that the second receiving cavity 20 can be opened or closed. When the second receiving cavity 20 is open, the user can add liquid to the second receiving cavity 20. When the cookware is in the cooking state or the storage state, the second receiving cavity 20 is closed to prevent foreign objects from entering and affecting the operation of the switch member 3.

[0087] In some embodiments, the movable member 22 and the base 21 may be slidably connected to block or open the second receiving cavity 20. In other embodiments, the movable member 22 and the base 21 may be rotatably connected to block or open the second receiving cavity 20.

[0088] For details, please refer to [link / reference]. Figure 11 As shown, the sliding fit between the movable part 22 and the base 21 can be specifically as follows: the movable part 22 has a limiting protrusion 222, the base 21 has a limiting groove and a limiting end (not shown in the figure), the limiting protrusion 222 slides along the limiting groove to realize the opening or closing of the second receiving cavity 20, and the limiting end is set along the sliding direction to prevent the movable part 22 from sliding off the base 21.

[0089] In other embodiments, the movable member 22 may be provided with a limiting groove, and the base 21 may be provided with a limiting protrusion. This application does not limit the specific cooperation method between the movable member 22 and the base 21.

[0090] In some embodiments, such as Figure 10 As shown, the base 21 may include a handle 211 and a water storage section 212. The handle 211 extends radially outward relative to the water storage section 212 along the cookware. The movable member 22 is slidably connected to the handle 211. The handle 211 is used by the user to grip the cookware, and the water storage section 212 is used to expand the water storage space of the second receiving cavity 20. Figure 2 and Figure 3 As shown, the second receiving cavity 20 includes a first cavity 211a and a second cavity 212a. The hand-held part 211 and the outer wall of the pot body 1 form the first cavity 211a, and the water storage part 212 and the outer wall of the pot body 1 form the second cavity 212a.

[0091] In this embodiment, by providing a handheld part 211 that extends radially outward relative to the water storage part 212, it is easy for the user to grip and move the cookware. The water storage part 212 also facilitates communication between the second cavity 212a and the first cavity 211a through the through hole 11. The handheld part 211 and the water storage part 212 provide the base 21 with a gripping function while also allowing for a larger water storage space, thus extending the user's reaction time in the event of the cookware drying out.

[0092] In some embodiments, such as Figure 2 , Figure 3 and Figure 10As shown, the second cavity 212a extends along the height direction of the pot, and the second cavity 212a has a first end 2121 that is away from the first cavity 211a. The through hole 11 on the pot body 1 is connected to the first end 2121 of the second cavity 212a. Along the direction away from the first cavity 211a, the cross-sectional area of ​​the first end 2121 gradually decreases, so that the flow velocity of the liquid in the first end 2121 along the direction away from the first cavity 211a gradually increases, which facilitates the liquid in the second cavity 212a to enter the first receiving cavity 10, thereby realizing the rapid opening of the switch 3.

[0093] In some embodiments, the outer wall of the first end 2121 may also be arc-shaped, which reduces the risk of liquid accumulating in the second cavity 212a and improves the anti-dry-burning effect of the cookware.

[0094] In some embodiments, such as Figure 2 and Figure 3 As shown, there is a second distance L2 between the bottom wall of the handle 211 and the bottom wall 13 of the pot body 1, where 0.7×H≤L2≤0.8×H. For example, the second distance L2 between the bottom wall of the handle 211 and the bottom wall 13 of the pot body 1 can be 0.7×H, 0.73×H, 0.75×H, 0.77×H, 0.8×H, etc.

[0095] In this embodiment, the distance between the bottom wall of the handle 211 and the bottom wall 13 of the pot body 1 is used to indicate the highest liquid level of the second cavity 212a. When the second distance L2 between the bottom wall of the handle 211 and the bottom wall 13 of the pot body 1 is too small, the distance between the handle 211 and the bottom wall 13 of the pot body 1 is too close, and the handle 211 is too close to the heating source at the bottom of the pot body 1, causing the temperature of the handle 211 to be too high. When the user holds the pot, it is easy to be burned by the handle 211 or the pot may slip due to the high temperature of the handle 211, increasing the safety risk of the user being directly or indirectly burned. In addition, the highest liquid level of the second cavity 212a is low, the hydraulic pressure in the second receiving cavity 20 is small, and there is a risk that the switch 3 cannot be turned on, affecting the anti-dry burning effect. When the second distance L2 between the bottom wall of the handle 211 and the bottom wall 13 of the pot body 1 is too large, with the height of the pot fixed, the increase of the second distance L2 will compress the height of the handle 211 and the first cavity 211a, reduce the material strength of the handle 211 and the water storage capacity of the first cavity 211a, and affect the use effect of the pot.

[0096] In this embodiment, the second distance L2 between the bottom wall of the handheld part 211 and the bottom wall 13 of the pot body 1 satisfies 0.7×H≤L2≤0.8×H, that is, the bottom height of the handheld part 211 is located at 70%-80% of the height of the pot body 1, and the second distance L2 between the bottom wall of the handheld part 211 and the bottom wall 13 of the pot body 1 is moderate, which can improve the reliability of the handheld part 211, increase the water storage capacity of the first cavity 211a, reduce the risk of user being scalded, and ensure that the switch 3 can be opened normally.

[0097] In some embodiments, such as Figure 10 As shown, the base 21 also includes an arc-shaped connecting part 214 for connecting the handle part 211 and the water storage part 212. The arc-shaped guiding design is more conducive to the flow of liquid in the first cavity 211a into the second cavity 212a. The liquid will not accumulate in the first cavity 211a, thus improving the anti-dry-burning effect of the cookware.

[0098] In some embodiments, such as Figure 11 As shown, the movable part 22 is also provided with an anti-slip part 223 to increase the friction when the movable part 22 slides. The movable part 22 includes a main body 221, the anti-slip part 223 is located on the main body 221, and the limiting protrusions 222 are located on both sides of the main body 221.

[0099] In some embodiments, such as Figure 1 and Figure 10 As shown, the handle assembly 2 has a transparent viewing area 213 that extends along the height of the cookware and has scale markings.

[0100] In this embodiment, on the one hand, the user can add an appropriate amount of liquid to the second receiving cavity 20 through the visible area 213 to ensure that the liquid level in the second receiving cavity 20 is between the highest and lowest liquid levels, so that the switch 3 can be opened normally and to prevent liquid from overflowing the second receiving cavity 20. On the other hand, during the cooking process, the user can judge whether the pot has dried out by observing the changes in the liquid level in the visible area 213, which increases the user's reaction time and reduces the safety risks during the use of the pot.

[0101] In this solution, the shape of the visible area 213 can be set to a strip shape. In other embodiments, the visible area 213 can also be set to a whole transparent area, an ellipse or other shapes. This application does not limit the specific shape of the visible area 213.

[0102] The specific working process of the cookware anti-dry-burning design in this embodiment is as follows:

[0103] During the use of the cookware, the user first adds liquid and food into the first receiving cavity 10. At this time, since the switch 3 is a one-way flow, the liquid and / or food in the first receiving cavity 10 will not enter the second receiving cavity 20.

[0104] Next, the user slides the movable part 22 radially along the cookware to open the second receiving cavity 20, and adds an appropriate amount of liquid according to the scale line in the visible area 213. The liquid enters the second cavity 212a from the first cavity 211a. The user slides the movable part 22 to close the second receiving cavity 20. At this time, because the liquid pressure in the second receiving cavity 20 is higher than the liquid pressure in the first receiving cavity 10, the elastic valve opens under the action of the liquid pressure in the second receiving cavity 20. The mating ends 312 of the diaphragm 31 move away from each other, the switch 3 opens, and the liquid in the second receiving cavity 20 flows unidirectionally into the first receiving cavity 10 through the switch 3 until the hydraulic pressure on both sides of the switch 3 is balanced. The elastic valve contracts, the mating ends 312 of the diaphragm 31 abut against each other, the switch 3 closes, and the cookware enters the cooking state.

[0105] As cooking time progresses, the water level in the first cavity 10 gradually decreases, generating liquid pressure on both sides of the switch 3. This means the liquid pressure in the second cavity 20 is higher than that in the first cavity 10. Under the influence of this liquid pressure, the elastic valve reopens, allowing liquid in the second cavity 20 to flow unidirectionally into the first cavity 10 through the switch 3, thus alleviating the dry-boiling phenomenon in the pot body 1. Repeating this process multiple times can improve the pot's ability to withstand dry cooking.

[0106] In addition, the water level in the second containment chamber 20 can be observed to drop through the viewing area 213, reminding the user to turn off the heating source and extending the user's reaction time when the cookware becomes dry.

[0107] In addition, when cleaning after cooking, users can also disassemble switch 3 separately for cleaning or replacement.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
