Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a cooking utensil. Background Technology

[0002] Many cooking appliances are equipped with water tanks to meet different functional needs such as water cooling and steam heating. In some appliances, the water tank is located internally and cannot be removed. This design makes it difficult for users to visually inspect the water level and to refill the tank promptly, making it inconvenient to use. Other appliances have externally mounted water tanks, which makes it easier for users to observe the water cooling process and add water. However, the tank often protrudes excessively from the appliance's surface, creating an unsightly appearance and increasing the overall size of the appliance, making it more difficult to store.

[0003] In response, Chinese patent CN221285385U discloses a cooking appliance with a water tank bubble. By setting an installation groove on the top of the appliance body and extending the installation groove to the side of the appliance body, an installation space is left for the water tank. After the water tank is installed, its top surface is flush with the top surface of the appliance body and its side surface is flush with the side surface of the appliance body, thereby improving the overall appearance quality of the appliance and the convenience of use and storage.

[0004] However, in the above solution, the body is a one-piece structure, meaning there is no relative movement between the part used to install the water tank and other parts of the body. Therefore, after the water tank is installed, its weight is stably applied to the bottom wall of the mounting groove. However, for cooking appliances like rice cookers and pressure cookers, which typically consist of a pot and a lid, some models have lids that can be flipped relative to the pot body for opening and closing. Therefore, when the water tank is installed on the lid as described above, in the closed state, the weight of the water tank is borne by the bottom wall of the mounting groove on the lid, making the water tank installation relatively stable. However, in the open state, when the lid is flipped upwards to a near-vertical position, the bottom wall of the mounting groove, i.e., the lid, loses its support for the water tank. At this point, the water tank, under its own weight, exerts force on the water connection points between the water tank and the cooking appliance, as well as on the connections of various pipes. Since these connections can only withstand limited forces, the water tank is prone to detaching, and the pipes may deform or fail to seal, leading to water leakage. Utility Model Content

[0005] This utility model provides a cooking appliance to solve the problem that when the water tank is placed on the pot lid, the pot lid's support for the water tank is weak when the lid is open, and the weight of the water tank is directly borne by the connection of each pipe, which leads to the water tank being easy to fall off and the seal failing.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A cooking appliance includes a pot body and a pot lid. The pot lid is movable relative to the pot body to open or close the pot body. The cooking appliance also includes a water tank. The pot lid is provided with a water-cooling cavity, and the water tank is connected to the water-cooling cavity. The top surface of the pot lid is provided with a mounting cavity for mounting the water tank. The mounting cavity extends laterally to the edge of the top surface of the pot lid. The mounting cavity is provided with a limiting rib along the circumference. The limiting rib is used to cooperate with the water tank stop to limit the water tank within the mounting cavity.

[0008] The mounting recess on the top surface of the pot lid extends to the side edge of the lid. This means that after the water tank is installed in the recess, the top surface of the water tank forms part of the top surface of the pot lid, and the side surface of the water tank forms part of the side surface of the pot lid. This ensures that both the top and side surfaces of the water tank are exposed and contribute to the overall appearance of the pot lid, making it easier to remove and place the water tank. Furthermore, the increased water tank area helps to reduce the height of the water tank, allowing for a more balanced design so that the top surface of the water tank does not protrude excessively from the top surface of the pot lid, and can even be flush with the top surface of the pot lid. This significantly reduces the height difference between the top surface of the water tank and the top surface of the pot lid, minimizing the overall obtrusiveness of the pot lid, improving its aesthetics and appearance, and reducing the overall volume of the pot lid in the height direction, thus contributing to miniaturization.

[0009] Furthermore, the mounting cavity is equipped with circumferential limiting ribs. The water tank is placed within the area enclosed by these ribs. When the pot lid is flipped open to a near-vertical position, the water tank is supported by the limiting ribs, thereby shifting the force exerted by the water tank on the pot lid to the limiting ribs. The limiting ribs have high strength and can withstand greater forces. Therefore, on the one hand, the installation of the water tank is more stable, preventing the water tank from falling off when the pot lid is raised. On the other hand, it can alleviate the stress on various pipelines, maintain good sealing performance, and prevent coolant leakage.

[0010] The side wall of the water tank is provided with a concave part and a blocking part located above the concave part. The concave part is located inside the limiting rib, and the blocking part blocks the limiting rib from above.

[0011] In this design, the concave portion is located inside the limiting rib to cooperate with the limiting rib in positioning the water tank, ensuring more accurate installation. When the lid is flipped upright, the concave portion and the limiting rib form a stop, providing support for the concave portion. The shielding portion is located above the concave portion, not only concealing the limiting rib and the gap between the limiting rib and the concave portion, but also reducing the height difference between the water tank's exterior and the lid's exterior, resulting in a more uniform appearance and minimizing the abruptness of the water tank installation. Furthermore, the area below the shielding portion provides operating space for the user's hands, allowing them to insert their fingers to grip the water tank for easier installation and removal.

[0012] The side wall of the mounting cavity is provided with a first fixing part, and the side wall of the water tank is provided with a second fixing part. The first fixing part and the second fixing part are inserted and matched, and the first fixing part or the second fixing part can reciprocate in the horizontal direction.

[0013] In this design, the first and second fixing parts are horizontally inserted and engaged, and one of them can reciprocate horizontally. This allows the water tank to be installed and removed at an angle, without needing to be kept horizontal or vertical. For example, the water tank can be tilted at an angle to engage the first and second fixing parts, securing one end. At this point, the opposite end of the water tank is tilted upwards. Then, this end is pressed down to secure it to the pot lid. Because either the first or second fixing part can move horizontally, they remain engaged throughout the pressing process. Alternatively, the water tank can be tilted at an angle to secure the opposite end of the water tank to the pot lid, with the end containing the second fixing part tilted upwards. Then, this end is pressed down, and during the pressing process, the second and first fixing parts engage. This makes the installation and removal of the water tank more flexible and convenient, and the user operation simpler and faster.

[0014] The bottom wall of the mounting cavity is provided with a third fixing part, and the bottom wall of the water tank is provided with a fourth fixing part. The fourth fixing part is rotatably connected to the water tank so that the fourth fixing part can rotate relative to the third fixing part to cooperate with the third fixing part to fix or disengage.

[0015] In this design, the third and fourth fixing parts can engage during the downward pressing of the water tank, thus securing the water tank to the lid at this end. The assembly method is simple and user-friendly, eliminating the need for complex operations. Simultaneously, the fourth fixing part can rotate to secure and unlock, further simplifying water tank removal and installation, thus enhancing the user experience.

[0016] The side of the water tank is provided with an inwardly recessed handle, and the fourth fixing part is located inside the handle.

[0017] In this design, the user can insert their hand into the latch to drive the fourth fixing part to rotate, thereby disengaging it from the third fixing part. At this point, the user can lift or pull out the water tank, making it more convenient for the user to apply force and achieving a hidden design for the fourth fixing part.

[0018] The mounting cavity is also provided with a passage for installing a pressure relief valve. The outer periphery of the passage is provided with an upward protruding baffle. The side wall of the water tank is provided with a clearance cavity corresponding to the passage. The cavity wall of the clearance cavity forms an exhaust channel that connects to the pressure relief valve. The clearance cavity and the baffle are positioned in conjunction.

[0019] In this design, the pressure relief valve is installed inside the through-hole. Gas ejected from the valve exits through the venting channel formed by the recessed cavity, thus achieving a centralized design for the water tank and venting position, improving the overall structural layout of the pot lid. The baffle protrudes upwards from the outer periphery of the through-hole, serving two purposes: firstly, it shields against liquid leakage from the recessed cavity, preventing liquid from flowing into the through-hole even if it leaks into the recess, thereby avoiding backflow into the pot through the pressure relief valve; secondly, the baffle positions itself against the cavity wall, further enhancing the positioning effect of the water tank installation.

[0020] The cooking appliance also includes a vent cover that closes the vent passage, the vent cover having an vent opening, and the vent cover being higher than the upper surface of the water tank.

[0021] In this design, the vent cap is higher than the top of the water tank, which provides a strong visual indication, allowing users to directly see the location of the high-temperature gas ejection and thus reducing the risk of burns from the high-temperature gas ejected from the vent cap during operation.

[0022] The cooking appliance includes a sealing element with a first mounting hole and a deformation part. The cooking appliance also includes a mounting base located below the sealing element, which has a second mounting hole and a push rod. The pressure relief valve passes through the first and second mounting holes, and the push rod acts on the deformation part to open the pressure relief valve.

[0023] In this design, the push rod does not directly act on the pressure relief valve; a seal is installed between them. When the push rod is driven upward, it contacts the deformable part of the seal, pushing it upward and thus opening the pressure relief valve. This ensures that the seal is always positioned between the pressure relief valve's outlet and the push rod, isolating the space between them and preventing gas or liquid from the pressure relief valve from reaching the space where the push rod is located, i.e., the inside of the pot lid. This ensures the cleanliness of the pot lid's interior and extends the lifespan of the electrical components.

[0024] The bottom wall of the mounting cavity is provided with a drain outlet, as well as a water outlet and a water return outlet for connecting with the water tank. Water baffles are provided around the outer periphery of the water return outlet and the water outlet.

[0025] In this design, if the water tank leaks, the liquid leaking into the mounting groove will flow primarily towards the drain outlet, making it difficult for it to bypass the baffle ribs and enter the water outlet and return inlet. This ensures that the leaked liquid is discharged at the designated location and cannot enter the pot lid through the water outlet and return inlet, preventing damage to the numerous electrical components inside the pot lid from water.

[0026] The lid has a connecting end that is rotatably connected to the pot body so that the lid can be flipped around the connecting end, and the mounting cavity extends to the connecting end.

[0027] In this design, the water tank is positioned closer to the connection end, making it closer to the rotation center of the lid. This results in a shorter lever arm between the water tank and the lid's rotation center. This shifts the lid's center of gravity further back, closer to the rotation center, thus reducing the torque required from the torsion spring. Simultaneously, the torsion spring experiences less stress, making it less prone to breakage or damage, increasing its lifespan, and saving costs. Furthermore, because the lid's center of gravity is closer to the connection end, it requires less effort for the user when opening and closing the lid. Attached Figure Description

In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0052] like Figure 1 , Figure 2 As shown, a cooking appliance includes a pot body and a pot lid 1. The pot lid 1 is movable relative to the pot body to open or close the pot body. The cooking appliance also includes a water tank 2. The pot lid 1 is provided with a water cooling cavity 71. The water tank 2 is connected to the water cooling cavity 71. The top surface of the pot lid 1 is provided with a mounting recess 11 for mounting the water tank 2. The mounting recess 11 extends laterally to the edge of the top surface of the pot lid 1. The mounting recess 11 is provided with a limiting rib 12 along the circumference. The limiting rib 12 is used to cooperate with the stop of the water tank 2 to limit the water tank 2 within the mounting recess 11.

[0053] It should be noted that this utility model does not limit the type of cooking appliance or the function of the water-cooling chamber 71. In one embodiment, the cooking appliance is an atmospheric pressure cooking appliance. During the cooking process, the water-cooling chamber 71 can cool the pot lid 1, thereby causing the bubbles and foam that rise to the surface of the pot to burst, thus preventing overflow during the venting process.

[0054] In a preferred embodiment, the cooking appliance is a pressure cooking appliance. After pressure cooking is completed, the pot can be cooled by water cooling chamber 71, thereby achieving rapid depressurization and facilitating quick opening of the lid.

[0055] The following uses a pressure cooking appliance as an example to illustrate the solution of this utility model in detail.

[0056] In this invention, the water tank 2 is connected to the water-cooling cavity 71 on the lid 1. After the pressure cooking is completed, the coolant in the water tank 2 circulates between the water tank 2 and the water-cooling cavity 71, thereby achieving water-cooling cooling and pressure reduction. This can greatly shorten the pressure reduction time, which helps to open the lid quickly. Compared with the exhaust pressure reduction method, the water-cooling pressure reduction process does not produce noise caused by air jets, resulting in a better user experience.

[0057] It should be noted that although this utility model is equipped with a water tank 2, which can reduce pressure by water cooling, the cooking appliance of this utility model can also be equipped with a pressure relief valve 4, so as to assist in reducing pressure by venting. By combining water cooling pressure reduction and venting pressure relief, more efficient pressure relief can be achieved.

[0058] The mounting recess 11 on the top surface of the pot lid 1 extends to the side edge of the pot lid 1. This allows the water tank 2, after being installed in the mounting recess 11, to have its top surface partially forming the top surface of the pot lid 1, and its side surface forming part of the side surface of the pot lid 1. This ensures that both the top and side surfaces of the water tank 2 are exposed on the pot lid 1, forming its overall appearance. Therefore, it is more convenient to remove and place the water tank 2. Furthermore, the increased area of ​​the water tank 2 helps to reduce its height, allowing for a more appropriate reduction in its height. This prevents the top surface of the water tank 2 from protruding excessively from the top surface of the pot lid 1, and may even allow it to be flush with the top surface of the pot lid 1. This significantly reduces the height difference between the top surface of the water tank 2 and the top surface of the pot lid 1, reducing the overall obtrusiveness of the pot lid 1, improving its aesthetics and appearance quality, and reducing the overall volume of the pot lid 1 in the height direction, thus contributing to miniaturization.

[0059] Preferably, the top surface of the water tank 2 is flush with the top surface of the pot lid 1 to improve the uniformity of the appearance of the pot lid 1. Of course, the top surface of the water tank 2 can also be higher or lower than the top surface of the pot lid.

[0060] Furthermore, the mounting cavity 11 is provided with limiting ribs 12 along the circumference. The water tank 2 is placed in the area enclosed by the limiting ribs 12. When the pot lid 1 is flipped open to a near-vertical position, the water tank 2 can be supported by the limiting ribs 12, thereby transferring the position of the force exerted by the water tank 2 on the pot lid 1 to the limiting ribs 12. The limiting ribs 12 have high strength and can withstand greater force. Therefore, on the one hand, the installation of the water tank 2 is more stable, preventing the water tank 2 from falling off when the pot lid 1 is raised. On the other hand, it can alleviate the stress on each pipeline, maintain good sealing performance, and prevent coolant leakage.

[0061] This utility model does not limit the assembly method of the pot lid 1 and the pot body. In one embodiment, the pot lid 1 can be removed from the pot body for the user to store separately. After removing the pot lid 1, the user can either stand the pot lid 1 upright on the table or place it horizontally on the table.

[0062] In a preferred embodiment, such as Figure 4 As shown, the pot lid 1 has a connecting end 111, which is rotatably connected to the pot body so that the pot lid 1 can be flipped around the connecting end 111, and the mounting cavity 11 extends to the connecting end 111.

[0063] The lid 1 is rotatably connected to the pot body, so that the lid 1 always remains connected to the pot body whether the lid is open or closed. This makes it easier to lay out the electrical wiring and water pipes, and saves users the trouble of storing the lid 1 separately, thus improving the user experience.

[0064] The water tank 2 is closer to the connecting end 111, making it closer to the rotation center of the lid 1. This results in a shorter lever arm between the water tank 2 and the rotation center of the lid 1. On one hand, this shifts the structural center of gravity of the lid 1 further back, closer to the rotation center, thus reducing the torque requirement of the torsion spring. On the other hand, the torsion spring experiences less stress, making it less prone to breakage or damage, increasing its lifespan and saving costs. Furthermore, because the center of gravity of the lid 1 is closer to the connecting end 111, it requires less effort for the user when opening and closing the lid.

[0065] Since the water tank 2 extends to the connection end 111, when the pot lid 1 is flipped open, the water tank 2 is located at the bottom of the pot lid 1. Under the gravity of the water tank 2, a pulling force is generated at the connection of each water pipe. Through the support formed by the limiting rib 12 and the outer edge of the water tank 2, the force can be transferred to the limiting rib 12, thereby improving the stability of the water tank 2 and the stability of the pipe connection.

[0066] Preferably, the water tank 2 is detachably installed in the mounting recess 11.

[0067] It should be noted that the overall area of ​​the water tank 2 can be smaller than the area enclosed by the limiting rib 12, so that the limiting rib 12 fits with the side wall of the water tank 2. Alternatively, a portion of the area of ​​the water tank 2 can be smaller than the area enclosed by the limiting rib 12, so that it can be accommodated within that area, while a portion of the area of ​​the water tank 2 is larger than that area. For example, as a preferred embodiment of this utility model, such as... Figure 3 , Figure 4 As shown, the side wall of the water tank 2 is provided with a concave portion 23 and a blocking portion 24 located above the concave portion 23. The concave portion 23 is located inside the limiting rib 12, and the blocking portion 24 blocks the limiting rib 12 from above.

[0068] The recessed portion 23 is located inside the limiting rib 12 to cooperate with the limiting rib 12 in positioning the water tank 2, making the installation position of the water tank 2 more accurate. When the pot lid 1 is flipped up, the recessed portion 23 and the limiting rib 12 form a stop, supporting the recessed portion 23 through the limiting rib 12. The shielding portion 24 is located above the recessed portion 23, which not only shields the limiting rib 12 and the gap between the limiting rib 12 and the recessed portion 23, but also reduces the height difference between the outer surface of the water tank 2 and the outer surface of the pot lid 1, making the appearance of the pot lid 1 more uniform and reducing the abruptness of the water tank 2 after installation. In addition, the lower part of the shielding portion 24 also leaves operating space for the user's hands, allowing the user to insert their fingers into this space to grasp the water tank 2, thus making it easier to install and remove the water tank 2.

[0069] Specifically, in one embodiment, the limiting rib 12 surrounds the mounting cavity 11 to form a fit with the sidewall of the water tank 2 in various circumferential areas. In a preferred embodiment, the limiting rib 12 is only provided on the side of the mounting cavity 11 near the connecting end 111. Alternatively, as... Figure 2 As shown, the mounting cavity 11 has a sidewall facing the center of the pot lid 1, which can fit with the sidewall of the water tank 2. Limiting ribs 12 are provided in the circumferential area of ​​the mounting cavity 11 excluding the sidewall. Furthermore, the height of the limiting ribs 12 gradually increases in the direction toward the connecting end 111.

[0070] In existing technology, the water tank is installed on a horizontal support surface, with its side resting against a vertical support surface. During installation, the water tank must be placed vertically from top to bottom, and during disassembly, the water tank must also be kept vertical when removed. This requires users to strictly control the angle of placement and removal when installing or removing the water tank; otherwise, the accuracy of positioning and the reliability of the seal will be affected. This operation is difficult and time-consuming.

[0071] As a preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the side wall of the mounting cavity 11 is provided with a first fixing part 15, and the side wall of the water tank 2 is provided with a second fixing part 21. The first fixing part 15 and the second fixing part 21 are inserted and engaged, and the first fixing part 15 or the second fixing part 21 can reciprocate in the horizontal direction.

[0072] The first fixing part 15 and the second fixing part 21 are horizontally inserted and engaged, and one of them can reciprocate horizontally. This allows the water tank 2 to be installed and removed at an angle, without needing to be kept horizontal or vertical. For example, the water tank 2 can be tilted so that the first fixing part 15 and the second fixing part 21 are inserted and engaged to fix this end. At this time, the other end of the water tank 2 opposite to the second fixing part 21 is in a raised position. Then, this end is pressed down to fix it to the pot lid 1. Since the first fixing part 15 or the second fixing part 21 can move horizontally, the first fixing part 15 and the second fixing part 21 remain engaged throughout the pressing down of the other end of the water tank 2. Alternatively, the water tank 2 can be tilted so that the other end opposite to the second fixing part 21 is fixed to the pot lid 1. At this time, the end containing the second fixing part 21 is in a raised position. Then, this end is pressed down, and during the pressing down, the second fixing part 21 and the first fixing part 15 are inserted. This makes the installation and removal of the water tank 2 more flexible and convenient, and the user operation simpler and faster.

[0073] Furthermore, such as Figure 4 , Figure 5 , Figure 7 As shown, the bottom wall of the mounting cavity 11 is provided with a third fixing part 16, and the bottom wall of the water tank 2 is provided with a fourth fixing part 22. The fourth fixing part 22 is rotatably connected to the water tank 2 so that the fourth fixing part 22 can rotate relative to the third fixing part 16 to cooperate with the third fixing part 16 to fix or disengage.

[0074] The third fixing part 16 and the fourth fixing part 22 can be engaged during the downward pressing of the water tank 2, thereby fixing the water tank 2 to the pot lid 1 at this end. The engagement method is simple and the user operation is more convenient, without the need for complicated operations. At the same time, the fourth fixing part 22 can rotate to fix and unlock, making it easier for the user to remove the water tank 2, realizing quick removal and quick installation of the water tank 2 and improving the user experience.

[0075] Preferably, the second fixing part 21 and the fourth fixing part 22 are located at both ends of the water tank 2, so that both ends of the water tank 2 are fixed to the pot lid 1, thereby improving the stability of the water tank 2.

[0076] Furthermore, such as Figure 3 , Figure 5 , Figure 7 As shown, the side of the water tank 2 is provided with an inwardly recessed handle position 25, and the fourth fixing part 22 is provided in the handle position 25.

[0077] The user can insert their hand into the latch 25 to drive the fourth fixing part 22 to rotate, thereby disengaging it from the third fixing part 16. At this time, the user can lift or pull out the water tank 2, making it more convenient for the user to apply force and achieving a hidden design for the fourth fixing part 22.

[0078] Specifically, such as Figure 6 As shown, the second fixing part 21 is a sliding buckle 211, and the first fixing part 15 is a insertion groove 151. The water tank 2 is provided with a slide for the sliding buckle 211 to slide. Further, a guide slope is provided on the lower side of the sliding buckle 211 and / or the insertion groove 151. Further, an elastic member is also provided at the sliding buckle 211 to provide a force for the sliding buckle 211 to extend toward the insertion groove 151. Of course, the first fixing part 15 can also be a sliding buckle 211, and the second fixing part 21 can be an insertion groove 151.

[0079] like Figure 7 As shown, the fourth fixing part 22 is rotatably connected to the water tank 2 via a rotating shaft. Both the fourth fixing part 22 and the third fixing part 16 are provided with snap-fit ​​fasteners, and a guide slope is provided on the opposite side of the snap-fit ​​fasteners. A torsion spring is also provided at the connection between the fourth fixing part 22 and the water tank 2 to provide a downward rotational force to the fourth fixing part 22. When the user inserts their hand into the latch position 25 to drive the fourth fixing part 22 to rotate upward, it causes the snap-fit ​​fastener below to rotate upward, thereby disengaging from the third fixing part. At this time, the user can lift or pull out the water tank 2, causing the sliding buckle 211 to disengage from the insertion groove 151 along the guide slope. At this time, the water tank 2 is separated from the pot lid 1.

[0080] Users can install the water tank 2 in two ways. One way is to first install the end where the second fixing part 21 is located. First, the water tank 2 is tilted so that the sliding buckle 211 is inserted into the insertion slot 151. At this time, the end where the fourth fixing part 22 is located is in a raised position. Then, press down on this end. During the pressing process, the guide slope of the snap-fit ​​buckle cooperates with each other and generates a pushing force, causing the fourth fixing part 22 to rotate upward until the fourth fixing part 22 passes the snap-fit ​​buckle of the third fixing part 16. Then, the fourth fixing part 22 rotates downward and resets under the action of the torsion spring, so that the two snap-fit ​​buckles are snapped and fixed.

[0081] Another method for installing the water tank 2 is to first install the end where the fourth fixing part 22 is located. First, the water tank 2 is tilted so that the fourth fixing part 22 is connected and fixed to the third fixing part. At this time, the end where the second fixing part 21 is located is in a raised position. Then, press down on this end. During the pressing process, the lower side of the sliding buckle 211 contacts the insertion groove 151 through the guide slope and generates a pushing force on the sliding buckle 211, so that the sliding buckle 211 passes through the groove wall of the insertion groove 151 and extends into the insertion groove 151 to complete the insertion.

[0082] When disassembling the water tank 2, insert your finger into the latch position 25 to drive the fourth fixing part 22 to rotate and loosen it from the third fixing part 16. Then lift the end upwards to pull the sliding buckle 211 out of the insertion slot 151.

[0083] This makes it possible to install and remove water tank 2 without having to keep it vertical or horizontal, making it more convenient for users to operate and easier and more comfortable to pick up and remove water tank 2, thus greatly improving the efficiency of installing and removing water tank 2.

[0084] Preferably, such as Figure 2 , Figure 3 , Figure 4 As shown, the mounting cavity 11 is also provided with a passage 18 for installing the pressure relief valve 4. The outer periphery of the passage 18 is provided with an upwardly protruding baffle 181. The side wall of the water tank 2 is provided with an avoidance cavity 26 corresponding to the passage 18. The cavity wall of the avoidance cavity 26 forms an exhaust channel 261 that connects to the pressure relief valve 4. The avoidance cavity 26 and the baffle 181 are positioned in cooperation.

[0085] The pressure relief valve 4 is installed inside the through-port 18. The gas ejected from its interior is discharged through the exhaust channel 261 formed by the clearance cavity 26, thus achieving a centralized design of the water tank 2 and the exhaust position, improving the overall structural layout of the pot lid 1. The baffle 181 protrudes upward from the outer periphery of the through-port 18. On the one hand, it can shield the liquid leaking from the mounting cavity 11. Even if the liquid in the water tank 2 leaks into the mounting cavity 11, it will not flow into the through-port 18, thereby preventing the liquid from flowing back into the pot through the pressure relief valve 4. On the other hand, the baffle 181 can form a positioning with the cavity wall of the clearance cavity 26, further improving the positioning effect of the water tank 2 installation.

[0086] Furthermore, the water tank 2 surrounds the pressure relief valve 4, achieving a concealed design. With the water tank 2 installed on the lid 1, the pressure relief valve 4 is not directly visible to the user from the outside of the lid 1, resulting in a cleaner appearance for the lid 1. On the other hand, the water tank 2, containing coolant, maintains a low temperature. Its surrounding area on at least part of the exhaust channel 261 cools the gas within the exhaust channel 261, causing bubbles rising with the gas to burst under the low temperature, leading to gas-liquid separation. The liquid then falls back under gravity, preventing liquid from spraying out of the exhaust channel 261 and contaminating the lid 1. Moreover, the low temperature reduces the kinetic energy of the gas flow, thus reducing the whistling sound during exhaust and improving the user experience.

[0087] Furthermore, such as Figure 1 , Figure 4 , Figure 5 As shown, the cooking appliance also includes a vent cover 3 that covers the vent passage 261. The vent cover 3 has a vent 31 and is higher than the upper surface of the water tank 2.

[0088] The exhaust cap 3 is higher than the top surface of the water tank 2, which makes the exhaust cap 3 have a strong visual indication effect, allowing users to directly know the location of the high-temperature gas, thereby reducing the risk of users being burned by the high-temperature gas emitted from the exhaust cap 3 during operation.

[0089] Preferably, such as Figure 1 , Figure 8 , Figure 9 As shown, a sealing element 5 is provided through the port 18. The sealing element 5 has a first mounting hole 52 and a deformation part 51. The cooking appliance also includes a mounting base 6 located below the sealing element 5. The mounting base 6 is provided with a second mounting hole 61 and a push rod 62. The pressure relief valve 4 passes through the first mounting hole 52 and the second mounting hole 61. The push rod 62 acts on the deformation part 51 to open the pressure relief valve 4.

[0090] The push rod 62 does not directly act on the pressure relief valve 4; a seal 5 is provided between them. When the push rod 62 is driven to move upward, it comes into contact with the deformable part 51 of the seal 5, pushing the deformable part 51 to bulge upward, thereby opening the pressure relief valve 4. This ensures that the seal 5 is always located between the vent of the pressure relief valve 4 and the push rod 62, isolating the space between them and preventing gas or liquid ejected from the pressure relief valve 4 from entering the space where the push rod 62 is located, i.e., the inside of the pot lid 1, thus ensuring the cleanliness of the inside of the pot lid 1 and the service life of the electrical components.

[0091] This invention does not limit the driving method of the push rod 62. It can be manually driven, i.e., the pot lid 1 is equipped with a venting button, and the user manually presses the venting button to drive the push rod 62 upward to lift the pressure relief valve 4 and release the air. Alternatively, it can be automatically vented, i.e., the pot lid 1 is equipped with a solenoid valve, and the solenoid valve is controlled by a program to drive the push rod 62 upward to lift the pressure relief valve 4 and release the air.

[0092] Preferably, the thickness of the deformable part 51 is reduced and / or a wrinkled layer is provided on the outer periphery of the deformable part 51 to improve the deformability of the deformable part 51, making it easier to deform when pushed by the push rod 62, and reducing the force of the deformable part 51 on other parts of the seal 5, so as to prevent the seal 5 from undergoing large-scale deformation and losing its sealing position.

[0093] like Figure 9 , Figure 10 As shown, the mounting base 6 has a third mounting hole 63, through which the push rod 62 passes. A positioning rib 621 is provided at the lower end of the push rod 62. An elastic reset member 622 is provided between the positioning rib 621 and the lower side of the mounting base 6. When the push rod 62 moves upward, the elastic reset member 622 is compressed, thus exerting a downward reset force on the push rod 62. A circumferentially extending annular groove 623 is provided on the portion of the push rod 62 located above the mounting base 6. A sealing ring is provided within the annular groove 623, the outer diameter of which is larger than the diameter of the third mounting hole 63, thus limiting the downward movement of the push rod 62.

[0094] As a preferred embodiment of this utility model, such as Figure 2As shown, the bottom wall of the mounting cavity 11 is provided with a drain outlet 17, as well as a water outlet 13 and a water return outlet 14 for docking with the water tank 2. Water baffles 131 are provided around the outer periphery of the water return outlet 14 and the water outlet 13.

[0095] If the water tank 2 leaks, the liquid leaking into the mounting groove will flow more towards the drain outlet 17, making it difficult for it to pass over the baffle 131 and enter the water outlet 13 and the water return outlet 14. This allows the leaked liquid to be discharged in a concentrated manner at a preset location, and prevents it from entering the interior of the pot lid 1 through the water outlet 13 and the water return outlet 14, thus avoiding damage to the many electrical components inside the pot lid 1 when exposed to water.

[0096] As a preferred embodiment, such as Figure 4 As shown, the pot lid 1 includes a lid body and an inner lid 19 located on the lower side of the lid body. The inner lid 19 cooperates with the pot body to form a cooking cavity. The lid body is provided with a cooling element 7. A water-cooled cavity 71 is located inside the cooling element 7. The cooling element 7 extends through the inner lid 19 into the cooking cavity.

[0097] The cooling component 7 is disposed on the cover, and the water-cooling cavity 71 is located inside the cooling component 7. The lower end of the cooling component 7 extends into the cooking cavity through the inner cover 19 to directly contact the high-temperature gas in the cooking cavity, thereby cooling the cooking cavity and achieving rapid pressure relief. Since the cooling component 7 is disposed on the cover, even if the inner cover 19 can rotate relative to the cover, the cover will not move, thus ensuring that the position of the cooling component 7 and the water-cooling pipeline connected to the cooling component 7 will not change. This ensures a stable connection and seal between the water-cooling pipeline and the water-cooling cavity 71, improving the reliability of the pipeline connection.

[0098] Furthermore, when the inner cover 19 is removed from the cover body, the cooling component 7 remains on the cover body and its position does not change with the installation and removal of the inner cover 19. This eliminates the need for users to connect the water-cooling pipes to the water-cooling cavity 71 during the installation of the inner cover 19, reducing the efficiency and ease of operation of the inner cover 19 installation and removal, and improving the user experience. On the other hand, the water-cooling pipes can always remain connected to the water-cooling cavity 71, eliminating the need for frequent connection, thus ensuring a tight seal and further reducing the risk of water-cooling liquid leakage, guaranteeing water-cooling efficiency.

[0099] In summary, after the water tank 2 and the water cooling cavity 71 of this utility model are connected by pipelines, in subsequent use, no matter whether the user rotates the inner cover 19 or removes the inner cover 19, the water cooling cavity 71 will never separate from the cover body, and the relative position between it and the water tank 2 will always remain fixed, with no relative movement between them. Therefore, the position of the pipeline also remains stable, and a reliable connection is always maintained.

[0100] It should be noted that although the cooling component 7 is located on the cover, so that the rotation and disassembly of the inner cover 19 will not affect the position of the cooling component 7 and the water-cooling cavity 71, the present invention does not limit whether the inner cover 19 can be rotated or whether the inner cover 19 can be disassembled.

[0101] In other embodiments, the cooling element 7 may also be disposed on the inner cover 19. For example, the cooling element 7 may be disposed on the upper or lower side of the inner cover 19, and the water-cooling cavity 71 may be located inside the cooling element 7, or the cooling element 7 may cooperate with the upper or lower surface of the inner cover 19 to form the water-cooling cavity 71.
