Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a water-cooled pressure cooking appliance. Background Art

[0002] After pressure cooking, pressure cookers need to release the pressure to equalize the pressure inside the pot with the outside atmosphere before the lid can be opened safely. Traditional pressure cookers release pressure through venting, which is not only slow but also noisy. The venting process can also cause liquid in the pot to spray out, contaminating the lid and affecting the user experience.

[0003] Some pressure cooking appliances also use water cooling for pressure relief. Compared to exhaust pressure relief, water cooling offers faster pressure relief and produces less noise during the process, leading to its increasing adoption in pressure cooking appliances. The water-cooling pressure relief assembly typically includes a water tank. In the prior art, some pressure cooking appliances incorporate the water tank into the lid. There are two common approaches to this placement: one is to conceal the water tank within the lid. While this approach allows for a concealed design, the user cannot see the water level within the tank and cannot easily refill the tank with coolant.

[0004] Another approach involves placing the water tank on top of the pot lid, leaving it exposed. This often requires the water tank to be significantly elevated above the lid's upper surface, making the lid's overall shape awkward and significantly increasing the space occupied by the cooking utensils. This significantly inconveniences both the use and storage of cooking utensils in a cramped kitchen. Furthermore, reducing the height of the water tank also reduces the surface area for the user to grip, making installation and removal more difficult and impacting the user experience. Utility Model Content

[0005] The utility model provides a water-cooled pressure cooking appliance to solve the problems that a water tank is exposed from a pot cover, resulting in an awkward shape of the pot cover and an increase in the volume of the cooking appliance, and that the water tank is inconvenient to take out and put away, affecting the portability of users in adding water.

[0006] The technical solution adopted by this utility model is:

[0007] A water-cooled pressure cooking appliance comprises a pot body, a pot lid, and a water tank arranged in the pot lid. The pot lid is provided with a cooling cavity, the water tank is connected to the cooling cavity, the top surface of the pot lid is provided with a mounting position, the mounting position extends to the edge of the pot lid, and the water tank is arranged in the mounting position so that the side surface of the water tank constitutes at least part of the appearance surface of the side portion of the pot lid, and the top surface of the water tank constitutes at least part of the appearance surface of the top portion of the pot lid.

[0008] The water-cooled pressure cooking appliance of the present invention also has the following additional technical features:

[0009] The top surface of the pot cover is provided with a decorative area, the top surface of the decorative area is higher than the installation position, the top surface of the water tank and the top surface of the decorative area are flush to jointly form the top appearance surface of the pot cover.

[0010] The pot lid is provided with an exhaust assembly, and the water tank has a water storage cavity and an exhaust cavity inside. The exhaust assembly is connected to the exhaust cavity, and an exhaust port is provided on the top surface of the water tank corresponding to the exhaust cavity. The water storage cavity surrounds at least a part of the exhaust cavity.

[0011] The water storage chamber includes a water outlet area and a water return area. The water outlet area is provided with a water outlet, and the water return area is provided with a water return outlet. The water outlet area and the water return area are relatively arranged on both sides of the exhaust chamber.

[0012] A cover plate is arranged between the bottom surface of the water tank and the pot cover. The water tank is provided with a communication port for communicating with the cooling cavity. The cover plate is provided with a water leakage port and a passage corresponding to the communication port.

[0013] The cover plate has upwardly protruding positioning ribs, which enclose an accommodating space. The water tank is arranged in the accommodating space, and a limiting convex rib is arranged on one side of the positioning ribs facing the water tank.

[0014] The water tank can be detachably installed at the installation position. The top surface of the pot cover also has a decorative area. There is a step surface between the decorative area and the installation position. The water tank has a first installation end close to the step surface and a second installation end away from the step surface. The first installation end is provided with a first fixing part, and the second installation end is provided with a second fixing part. The step surface is provided with a first matching part for cooperating and fixing with the first fixing part, and the installation area is provided with a second matching part for cooperating and fixing with the second fixing part.

[0015] The first fixing portion and the second fixing portion are plug-fitted, and the first fixing portion can reciprocate in a horizontal direction.

[0016] The second fixing part is rotatably connected to the water tank so that the second fixing part can move relative to the second matching part to cooperate with or release the second matching part. The side of the water tank is provided with an inwardly concave hand-picking position, and the second fixing part is arranged in the hand-picking position.

[0017] The water tank is provided with a water outlet and a return water outlet connected to the cooling chamber. A sealing member is provided at the return water outlet or the water outlet. The sealing member can move relative to the water tank to open or block the return water outlet or the water outlet. The sealing member is provided with a water flow switch, and the pot lid is provided with a triggering member for driving the water flow switch to open.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the present invention, the mounting position of the pot lid top extends to the edge of the pot lid. When the water tank is installed in the mounting position, the top surface of the water tank constitutes part of the appearance surface of the pot lid top, and the side surface of the water tank constitutes part of the appearance surface of the side portion of the pot lid. As a result, the top and side surfaces of the water tank are both exposed to the pot lid and constitute the appearance surface of the pot lid. Therefore, when removing or placing the water tank, the user can grasp the side and top surfaces of the water tank at the same time. By applying force to the two surfaces at an angle to each other, the user can apply force more conveniently and operate more comfortably. In this way, the water tank can be easily removed from the mounting position or installed in the mounting position, which not only facilitates the installation and removal of the water tank, but also helps to reduce the height of the water tank. The height of the water tank can be appropriately reduced so that the top surface of the water tank does not protrude too much from the top surface of the pot lid, and can even be made flush with the top surface of the pot lid. This greatly reduces the height difference between the top surface of the water tank and the top surface of the pot cover, reduces the overall abruptness of the pot cover, improves the aesthetics and appearance quality, and reduces the overall volume of the pot cover in the height direction, which helps to miniaturize it.

[0020] 2. As a preferred embodiment of the present invention, the top surface of the pot lid has a decorative area. The top surface of the decorative area is higher than the mounting position, and the top surface of the water tank and the top surface of the decorative area are flush, thereby forming the top appearance of the pot lid. By lowering the top surface of the mounting position so that it is lower than the decorative area, a clearance is formed for the water tank. Therefore, after the water tank is installed, the height difference between the mounting position and the decorative area compensates for at least part of the height of the water tank, allowing the top surface of the water tank to be flush with the decorative area, making the top surface of the pot lid a large flat surface, improving the overall appearance and uniformity, reducing the volume of the cooker, and making the product appearance more consistent with the user's impression of the product.

[0021] 3. As a preferred embodiment of the present invention, the pot lid is provided with an exhaust assembly. The water tank has a water storage chamber and an exhaust chamber within it. The exhaust assembly communicates with the exhaust passage. An exhaust port is provided on the top surface of the water tank, corresponding to the exhaust chamber, and the water storage chamber surrounds at least a portion of the exhaust chamber. The exhaust chamber within the water tank communicates with the exhaust assembly on the pot lid, allowing the exhaust assembly to be exhausted through the exhaust chamber within the water tank. This design allows for a concealed exhaust assembly. When the water tank is installed on the pot lid, the exhaust assembly is not directly visible from the outside of the pot lid, further enhancing the pot lid's appearance. Furthermore, the water storage chamber, due to the coolant stored within it, maintains a low temperature. This coolant surrounding at least a portion of the exhaust chamber cools the gas within the exhaust chamber, causing bubbles that rise with the gas into the exhaust chamber to burst at the low temperature, resulting in gas-liquid separation. The liquid then falls back under gravity, preventing liquid from escaping from the exhaust chamber outlet and contaminating the pot lid. Furthermore, the low temperature reduces the kinetic energy of the gas flow, thereby reducing the whistling sound of the airflow during exhaust, achieving the goal of exhaust noise and improving the user experience.

[0022] 4. As a preferred embodiment of the present invention, the water tank is removably mounted to the mounting position. The top surface of the pot lid further comprises a decorative area, with a stepped surface between the decorative area and the mounting position. The water tank comprises a first mounting end proximal to the stepped surface and a second mounting end distal to the stepped surface. The first mounting end is provided with a first fixing portion, and the second mounting end is provided with a second fixing portion. The stepped surface is provided with a first mating portion for mating with the first fixing portion, and the mounting area is provided with a second mating portion for mating with the second fixing portion. The first and second fixing portions are located at opposite ends of the water tank and respectively mated with the pot lid. This not only secures the water tank at both ends, preventing tilting of one end of the water tank and maintaining the top surface of the water tank parallel to the top surface of the pot lid, but also ensures that the first fixing portion and the first mating portion mate on the vertical stepped surface to restrain the water tank in the vertical direction. The second fixing portion and the second mating wall mate on the horizontal surface of the mounting area to restrain the water tank in the horizontal direction. This provides multi-directional positioning of the water tank, improves the stability of the water tank, significantly reduces swaying of the water tank, and enhances structural stability.

[0023] 5. As a preferred embodiment of the present invention, the water tank is provided with a water outlet and a water return port connected to the cooling chamber, a blocking piece is provided at the water return port or the water outlet, the blocking piece can move relative to the water tank to open or block the water return port or the water outlet, the blocking piece is provided with a water flow switch, and the pot lid is provided with a triggering piece for driving the water flow switch to open. The blocking piece is provided at the water outlet or the water return port, and can move to open or close the port, so that the water outlet or the water return port here can simultaneously realize the function of connecting with the cooling chamber and the user replenishing the coolant into the water tank. The user can open the blocking piece and replenish the coolant into the water tank. After replenishment, the blocking piece is closed. At this time, after the water tank is installed on the pot lid, the triggering piece triggers the water flow switch of the blocking piece, so that the port is connected with the cooling chamber. This multi-purpose piece simplifies the structure of the water tank, reduces the number of openings, reduces the difficulty of sealing and the risk of coolant leakage.

[0050] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0053] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0054] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0055] like Figure 1 、 Figure 2 、 Figure 3 As shown, a water-cooled pressure cooking device includes a pot body and a pot cover 1, the pot cover 1 includes a pot cover 1 and a water tank 2 arranged on the pot cover 1, the pot cover 1 is provided with a cooling cavity 16, the water tank 2 is connected to the cooling cavity 16, the top surface of the pot cover 1 is provided with a mounting position 12, the mounting position 12 extends to the edge of the pot cover 1, and the water tank 2 is arranged in the mounting position 12 so that the side surface of the water tank 2 constitutes at least part of the appearance surface of the side portion of the pot cover 1, and the top surface of the water tank 2 constitutes at least part of the appearance surface of the top of the pot cover 1.

[0056] By using water cooling to reduce the pressure, there is no need to exhaust by opening the exhaust valve when releasing the pressure. While ensuring the pressure relief speed, the whistling sound of the air flow during exhaust is reduced, thereby reducing noise, and no liquid is sprayed out to cause pollution to the pot cover 1, thereby greatly improving the user experience.

[0057] Preferably, if Figure 2 、 Figure 3 、 Figure 14 As shown, the side of the water tank 2 is flush with the side of the pot cover 1, so that the side appearance of the pot cover 1 is more uniform and flat. Of course, the side of the water tank 2 can also be made to protrude from the side of the pot cover 1, so that the user can easily remove the water tank 2 by grabbing the protruding part of the water tank 2, thereby improving portability.

[0058] In the present invention, the mounting position 12 on the top surface of the pot cover 1 extends to the edge of the pot cover 1. When the water tank 2 is mounted on the mounting position 12, the top surface of the water tank 2 constitutes part of the exterior surface of the top of the pot cover 1, and the side surfaces of the water tank 2 constitute part of the exterior surface of the side of the pot cover 1. As a result, both the top and side surfaces of the water tank 2 are exposed from the pot cover 1 and constitute the exterior surface of the pot cover 1. Therefore, when removing or placing the water tank 2, the user can grasp the side and top surfaces of the water tank 2 simultaneously. By applying force to the two mutually angled surfaces, the user can more easily apply force and the operation is more comfortable. In this way, the water tank 2 can be easily removed from or mounted to the mounting position 12, which not only facilitates the installation and removal of the water tank 2, but also helps reduce the height of the water tank 2. The height of the water tank 2 can be appropriately reduced so that the top surface of the water tank 2 does not protrude too much from the top surface of the pot cover 1, and can even be made flush with the top surface of the pot cover 1. This greatly reduces the height difference between the top surface of the water tank 2 and the top surface of the pot cover 1, reduces the overall abruptness of the pot cover 1, improves the aesthetics and appearance quality, and reduces the overall volume of the pot cover 1 in the height direction, which helps to miniaturize it.

[0059] Specifically, such as Figure 1 As shown, the water tank 2 is a flat structure. Taking the removal of the water tank 2 as an example, the user can simultaneously grasp the side and top surfaces of the water tank 2 from the edge of the pot lid 1. Because the top and side surfaces are perpendicular or at an angle to each other, this gripping method makes it easier for the user to apply force to the water tank 2. At this time, the user can apply vertical upward force to lift the water tank 2 vertically, apply horizontal force to pull the water tank 2 out horizontally, or apply upward force to tilt the edge of the water tank 2 so that one end is tilted, and then continue to flip the water tank 2 upward to remove it from the pot lid 1. The specific method of removing the water tank 2 is not limited by this utility model.

[0060] It should be noted that the present invention does not limit the positional relationship between the top surface of the water tank 2 and the top surface of the pot cover 1, and it can be one of the following embodiments:

[0061] Implementation method 1: In this implementation method, Figure 2 、 Figure 3 、 Figure 14 As shown, the top surface of the pot cover 1 has a decorative area 11 , the top surface of the decorative area 11 is higher than the installation position 12 , and the top surface of the water tank 2 and the top surface of the decorative area 11 are flush to jointly constitute the top appearance surface of the pot cover 1 .

[0062] By sinking the top surface of the mounting position 12 so that it is lower than the decorative area 11, a gap is formed for the water tank 2. Therefore, after the water tank 2 is installed, the height difference between the mounting position 12 and the decorative area 11 makes up for at least part of the height of the water tank 2, so that the top surface of the water tank 2 can be flush with the decorative area 11, so that the appearance of the top surface of the pot cover 1 is a large plane, which improves the overall appearance and uniformity, reduces the volume of the cooker, and makes the product appearance more in line with the user's impression of the product.

[0063] It should be noted that due to factors such as manufacturing and assembly errors, the top surface of the water tank 2 may not be completely flush with the decorative area 11. The present invention allows for a certain range of height difference between the two due to factors such as errors. Furthermore, the top surface of the pot lid 1 can be horizontal or a slope that gradually rises or falls from one end to the other, as long as the top surface of the water tank 2 and the top surface of the decorative area 11 conform to the overall shape of the pot lid 1.

[0064] Specifically, to further enhance the aesthetics of pot lid 1, the top surface of pot lid 1 can be further enhanced through injection molding, application of a film, or provision of a decorative layer. Similarly, the top surface of water tank 2 can also undergo the aforementioned processing to enhance the overall appearance of pot lid 1. When both the top surface of decorative region 11 and the top surface of water tank 2 are provided with a decorative layer or film, the upper surface of the decorative layer or film on the top surface of water tank 2 is flush with the decorative layer or film on the top surface of pot lid 1.

[0065] Embodiment 2: In this embodiment, the top surface of the water tank 2 is higher or lower than the top surface of the decorative area 11 to form a step structure on the top appearance surface of the pot cover 1. Since the area of ​​the installation position 12 is large, after the water tank 2 is installed, the water tank 2 and the decorative area 11 divide the top surface of the pot cover 1 into two large areas. There is a height difference between the two areas, which can also ensure the appearance quality of the pot cover 1 to a certain extent.

[0066] Preferably, a transparent window is provided on the side of the water tank 2 so that the user can see the amount of water in the water tank 2 from the side of the pot cover 1 .

[0067] Specifically, the arrangement of the mounting position 12 and the decorative area 11 on the top surface of the pot cover 1 can be Figure 1 For example, the decorative area 11 is located at the front of the pot cover 1, and the water tank 2 is installed at the rear of the pot cover 1. Alternatively, the water tank 2 and the decorative area 11 can be arranged side by side. For another example, the installation position 12 surrounds the outer periphery of the decorative area 11, and the water tank 2 is correspondingly configured as a ring structure, which is not limited here.

[0068] In a preferred embodiment, Figure 2 、 Figure 7As shown, the pot cover 1 is provided with an exhaust assembly, and the water tank 2 has a water storage chamber 21 and an exhaust chamber 22 inside. The exhaust assembly is connected to the exhaust chamber 22, and an exhaust port 221 is provided on the top surface of the water tank 2 corresponding to the exhaust chamber 22. The water storage chamber 21 surrounds at least a part of the exhaust chamber 22.

[0069] An exhaust chamber 22 is provided within the water tank 2 and communicates with the exhaust assembly on the pot lid 1, allowing the exhaust assembly to exhaust through the exhaust chamber 22 within the water tank 2. This, on the one hand, allows for a concealed design of the exhaust assembly. When the water tank 2 is installed in the pot lid 1, the user cannot directly see the exhaust assembly from the outside of the pot lid 1, thereby making the pot lid 1 more concise in appearance. On the other hand, the water storage chamber 21 is kept at a relatively low temperature due to the storage of coolant. The coolant surrounding at least a portion of the exhaust chamber 22 can cool the gas within the exhaust chamber 22, causing bubbles that rise with the gas into the exhaust chamber 22 to rupture under the influence of the low temperature, thereby separating the gas and liquid. The liquid then falls back under the influence of gravity, thereby preventing the liquid from being ejected from the outlet of the exhaust chamber 22 and contaminating the pot lid 1. Furthermore, the low temperature can reduce the kinetic energy of the gas flow, thereby reducing the whistling sound of the airflow during the exhaust process, achieving the purpose of exhaust noise and improving the user experience.

[0070] Specifically, such as Figure 7 As shown, a side wall of one side of the water tank 2 is provided with a concave section, and the concave section cooperates with the side wall of the installation position 12 to form an exhaust cavity 22.

[0071] The exhaust assembly includes a pressure relief valve 13 and a float valve 14. The exhaust chamber 22 and the pressure relief valve 13 are arranged in correspondence with each other up and down, so that the pressure relief valve 13 partially extends into the exhaust chamber 22. The float valve 14 and the exhaust chamber 22 are staggered up and down. The pot cover 1 is provided with an air outlet channel 15 connected to the float valve 14. The air outlet channel 15 is connected to one side of the exhaust chamber 22 so that the gas discharged from the float valve 14 enters the exhaust chamber 22 from one side of the exhaust chamber 22.

[0072] Further, if Figure 7 、 Figure 9 、 Figure 12 As shown, the water storage chamber 21 includes a water outlet area 211 and a water return area 212 . The water outlet area 211 is provided with a water outlet 28 , and the water return area 212 is provided with a water return port 29 . The water outlet area 211 and the water return area 212 are arranged on both sides of the exhaust chamber 22 .

[0073] The walls of the exhaust chamber 22 act as a barrier to the liquid in the return water area 212 and the water outlet area 211. Water in the water tank 2 flows out through the water outlet 28 into the cooling chamber 16. The heated liquid in the cooling chamber 16 then flows back into the water tank 2 through the return port. The return port 29 is located in the return water area 212. This allows the higher-temperature liquid to flow back into the water tank 2. Due to the restriction of the walls of the exhaust chamber 22, it is preferentially stored in the return water area 212 and does not flow excessively into the water outlet area 211. This ensures that the water in the water outlet area 211 remains at a relatively low temperature, which is used to cool the pot lid 1. This slows down the mixing of cold water and hot water in the water tank 2 to a certain extent, so that the hot water is concentrated more in the return water area 212, while the cold water is concentrated more in the water outlet area 211, thereby ensuring that the liquid flowing from the water outlet 28 to the pot cover 1 is at a lower temperature, ensuring the temperature difference between the liquid and the pot cover 1, and thus ensuring the water cooling effect, which helps to quickly cool down and relieve pressure, and realize quick opening of the cover.

[0074] Preferably, if Figure 7 As shown, the side wall of the water tank 2 opposite to the exhaust chamber 22 is provided with an inwardly recessed handle 23, and a connecting passage 213 is formed between the wall of the handle 23 and the wall of the exhaust chamber 22, connecting the water outlet area 211 and the return water area 212. The water outlet area 211 and the return water area 212 are connected, which increases the storage capacity of cold water in the water tank 2. When adding water to the water tank 2, the water tank 2 can be completely filled so that cold water is stored in the water outlet area 211 and the return water area 212 at the same time. When hot water flows back into the water tank 2, it first reaches the return water area 212. However, the connecting passage 213 is relatively small, so the hot water in the return water area 212 cannot flow to the water outlet area 211 in large quantities, and can only flow to the water outlet area 211 at a relatively slow speed. At the same time, hot water continuously enters the return water area 212 through the return port, which can also promote the cold water originally in the return water area 212, pressing the cold water in the return water area 212 into the water outlet area 211, and then replenishing cold water into the water outlet area 211, ensuring sufficient water-cooling liquid, so that more cold water flows to the pot cover 1 during the water cooling process.

[0075] Preferably, if Figure 1 、 Figure 10 As shown, a cover plate 3 is provided between the bottom surface of the water tank 2 and the pot cover 1. The water tank 2 is provided with a communication port for communicating with the cooling chamber 16. The cover plate 3 is provided with a water leakage port 36 and a passage 35 provided corresponding to the communication port.

[0076] The connecting port of the water tank 2 is connected to the cooling chamber 16 through the port 35. The setting of the leakage port 36 makes it easy for the coolant leaked from the water tank 2 to the cover plate 3 and the liquid sprayed out during the exhaust process of the exhaust component to flow out through the leakage port 36 and be discharged or collected, avoiding accumulation on the cover plate 3 and reducing the risk of leakage to the bottom of the cover plate 3, thereby ensuring the dryness of the internal components and electrical elements of the pot cover 1 and reducing the risk of malfunction due to water.

[0077] Specifically, the communication port includes a water outlet 28 and a water return port 29. Of course, there can also be one communication port, so that the water outlet and the water return port share one communication port.

[0078] Preferably, a drainage channel is provided inside the pot cover 1 and is connected to the water leakage port 36 so as to drain the liquid flowing out of the water leakage port 36 to the pot cover 1 or the water collecting part of the pot body for collection.

[0079] In one embodiment, a sealing ring is provided at the opening 35 to seal the gap between the connecting port and the opening 35. In another embodiment, an upwardly protruding water retaining rib 351 is provided on the periphery of the opening 35 to prevent liquid leaking onto the cover plate 3 from flowing toward the leaking port 36 and from flowing over the water retaining rib 351 and entering the opening 35.

[0080] Preferably, if Figure 10 As shown, the water leakage port 36 is provided near the exhaust cavity 22 of the water tank 2 so as to collect the liquid sprayed out by the exhaust assembly.

[0081] In one embodiment, if Figure 10 As shown, the cover plate 3 has an upwardly protruding positioning rib 37 , which encloses an accommodating space. The water tank 2 is disposed in the accommodating space. A limiting rib 371 is provided on one side of the positioning rib 37 facing the water tank 2 .

[0082] On the one hand, the positioning ribs 37 can form a position with the water tank 2, allowing the user to quickly align the water tank 2 with the accommodating space and complete the installation of the water tank 2. On the other hand, the positioning ribs 37 can collect the liquid leaking from the water tank 2, preventing the leaked liquid from passing through the cover plate 3 to the bottom of the cover plate 3, and preventing it from overflowing laterally to other areas of the pot cover 1. It also makes it convenient for the user to clean the liquid collected on the cover plate 3. Preferably, the bottom wall of the accommodating space is a flat structure.

[0083] The positioning ribs 37 may be directly engaged with the side wall of the water tank 2, or, as Figure 13 As shown, the bottom of the side wall of the water tank 2 is provided with an inner recess 264 for cooperating with the positioning rib 37, so that after the water tank 2 is installed, the positioning rib 37 is shielded above the positioning rib 37.

[0084] The limiting ribs 371 can be evenly arranged along the circumference of the water tank 2, or can be arranged in the front, back, left, and right directions of the water tank 2, so that the limiting ribs 371 and the outer wall of the water tank 2 form a stop limit to reduce the shaking of the water tank 2.

[0085] Preferably, if Figure 3 、 Figure 4As shown, the water tank 2 can be detachably installed at the mounting position 12, the top surface of the pot cover 1 also has a decorative area 11, and a step surface 32 is provided between the decorative area 11 and the mounting position 12. The water tank 2 has a first mounting end 24 close to the step surface 32, and a second mounting end 25 away from the step surface 32. The first mounting end 24 is provided with a first fixing portion, and the second mounting end 25 is provided with a second fixing portion 251. The step surface 32 is provided with a first matching portion for matching and fixing with the first fixing portion, and the mounting area is provided with a second matching portion 34 for matching and fixing with the second fixing portion 251.

[0086] The first fixing portion and the second fixing portion 251 are located at both ends of the water tank 2 and are respectively fixed to the pot cover 1, which not only fixes the two ends of the water tank 2, but also prevents one end of the water tank 2 from tilting up, and keeps the top surface of the water tank 2 parallel to the top surface of the pot cover 1.

[0087] Specifically, the step surface 32 is a transition surface between the decorative area 11 and the installation position 12. The first fixing portion and the first matching portion cooperate on the vertical step surface 32 to form a vertical limit for the water tank 2. The second fixing portion 251 and the second matching wall cooperate on the horizontal surface of the installation area to form a horizontal limit for the water tank 2, thereby limiting the water tank 2 in multiple directions, improving the fixing stability of the water tank 2, greatly reducing the shaking of the water tank 2, and improving the structural stability.

[0088] Furthermore, if Figures 3 to 5 As shown, the first fixing portion and the second fixing portion 251 are plugged together, and the first fixing portion can reciprocate in the horizontal direction. Figure 4 As shown, a cover plate 3 is provided between the pot cover 1 and the water tank 2, the step surface 32 is provided on the cover plate 3, and the corresponding first matching portion is also provided on the cover plate 3. Similarly, the second matching portion 34 can also be provided on the pot cover 1 or the cover plate 3.

[0089] Specifically, such as Figure 4 As shown, one of the first fixing portion and the first matching portion is a sliding buckle 241, and the other is a plug-in slot 33, and the two are plugged together horizontally. Figure 4 、 Figure 5 As shown, a slider 241 is slidably connected to the water tank 2, and a plug-in slot 33 is provided on the stepped surface 32. The water tank 2 is provided with a slideway 242 for the slider 241 to slide. The slider 241 is also provided with a limit hook 243 to prevent the slider 241 from falling out of the slideway 242. Furthermore, a guide slope 244 is provided on the underside of the slider 241 and / or the plug-in slot 33. Furthermore, an elastic member is provided on the slider 241 to provide a force for the slider 241 to extend toward the plug-in slot 33.

[0090] like Figure 6As shown, the second fixing portion 251 is rotatably connected to the water tank 2 so that the second fixing portion 251 can move relative to the second matching portion 34 to be fixed or released with the second matching portion 34. The side of the water tank 2 is provided with an inwardly recessed hand-picking position 23, and the second fixing portion 251 is provided in the hand-picking position 23.

[0091] Specifically, such as Figure 6 、 Figure 8 、 Figure 11 As shown, the second fixing portion 251 has an operating end 2511, a clamping end 2512, and a connecting portion 2513 located therebetween. The connecting portion 2513 is rotatably connected to the water tank 2 via a rotating shaft. The clamping end 2512 and the second matching portion 34 are both provided with a clamping buckle, and a guide slope 341 is provided on the side opposite the clamping buckle. The connecting portion 2513 is also provided with a torsion spring for providing a downward rotation force to the second fixing portion 251. When the user extends his hand into the hand-picking position 23 to drive the operating end 2511 to rotate upward, the clamping end 2512 below is driven to rotate upward, thereby loosening from the second matching portion 34. At this time, the user can lift or pull out the water tank 2, causing the slider 241 to disengage from the insertion slot 33 along the guide slope 244. At this time, the water tank 2 is detached from the pot cover 1.

[0092] Among them, such as Figure 8 、 Figure 12 As shown, the water tank 2 is provided with a stop rib 262 below the operating end 2511 to limit the user's driving direction of the second fixing portion 251 so that the operating end 2511 can only swing upward. Figure 12 As shown, the box body 26 and the box cover 27 are respectively provided with arc ribs 263. After the two are assembled, the upper and lower arc ribs 263 cooperate to form a fixed position for accommodating the rotating shaft.

[0093] The user can install the water tank 2 in two ways. One is to install the first mounting end 24 first, first tilt the water tank 2 at an inclined angle so that the sliding buckle 241 of the first mounting end 24 is plugged into the plug-in slot 33. At this time, the second mounting end 25 is in a tilted posture, and then press down the second mounting end 25. During the pressing process, the guiding inclined surfaces 341 of the snap buckle cooperate with each other and generate a pushing force, so that the operating member drives the second fixing portion 251 to rotate upward until the second fixing portion 251 passes over the second matching portion 34. The operating member drives the second fixing portion 251 to rotate downward and reset under the action of the torsion spring, so that the two snap buckles are snapped and fixed.

[0094] Another way to install the water tank 2 is to first install the second mounting end 25, and first fix the water tank 2 at an inclined angle so that the second fixing portion 251 of the second mounting end 25 is clamped and fixed with the second matching portion 34. At this time, the first mounting end 24 is in a tilted posture, and then press down the first mounting end 24. During the pressing process, the lower side of the slider 241 contacts the plug-in slot 33 through the guide slope 244, and generates a pushing force on the slider 241, so that the slider 241 passes over the slot wall of the plug-in slot 33 and extends into the plug-in slot 33 to complete the plug-in.

[0095] Specifically, such as Figure 7 、 Figure 8 As shown, the water tank 2 includes a box body 26 and a box cover 27, which can be a separate structure fixed by ultrasonic welding or the like, or can be integrally formed. The side wall of the box body 26 has an inwardly concave recess 261, and the lower side of the box cover 27 cooperates with the recess 261 to form a gripping position 23. Similarly, as Figure 10 As shown, there is a cover plate 3 between the water tank 2 and the top surface of the pot cover 1, and the cover plate 3 is provided with an avoidance notch 38 corresponding to the recessed portion 261 to facilitate the user to insert his fingers into the hand-picking position 23.

[0096] As a preferred embodiment of the present invention, Figure 7 、 Figures 14 to 17 As shown, the water tank 2 is provided with a water outlet 28 and a return water port 29 connected to the cooling chamber 16, and a blocking member 7 is provided at the return water port 29 or the water outlet 28. The blocking member 7 can move relative to the water tank 2 to open or block the return water port 29 or the water outlet 28. The blocking member 7 is provided with a water flow switch 281, and the pot cover 1 is provided with a trigger member for driving the water flow switch 281 to open.

[0097] The blocking member 7 is provided at the water outlet 28 or the water return port 29 and can be moved to open or close the port, so that the water outlet 28 or the water return port 29 can simultaneously realize the communication with the cooling chamber 16 and the function of the user to replenish the coolant into the water tank 2. The user can open the blocking member 7 to replenish the coolant into the water tank 2. After the replenishment is completed, the blocking member 7 is closed. At this time, after the water tank 2 is installed on the pot cover 1, the trigger member triggers the water flow switch 281 of the blocking member 7, so that the port is connected with the cooling chamber 16. This multi-purpose piece simplifies the structure of the water tank 2, reduces the number of openings, reduces the difficulty of sealing and the risk of coolant leakage.

[0098] Specifically, in one embodiment, Figure 7 、 Figure 14 As shown, the blocking member 7 is arranged at the water outlet 28, and the blocking member 7 is rotatably connected to the water tank 2 via a rotating shaft so that the blocking member 7 can be turned over to open or block the water outlet 28. Figure 13As shown, the outer periphery of the water outlet 28 is provided with a groove 265 for accommodating the blocking member 7 to prevent the blocking member 7 from excessively protruding from the surface of the water tank 2. Of course, the blocking member 7 can also open or block the water outlet 28 by moving horizontally or being detachable from the water tank 2, which is not limited here. Figure 17 As shown, the blocking member 7 has a sealing plug 71 inserted into the water outlet 28, and an installation channel 72 for installing the water flow switch 281 is provided inside the sealing plug 71.

[0099] Preferably, the water outlet 28 and the water return port 29 are both arranged on the bottom surface of the water tank 2, so that after the user adds water to the water tank 2 and before installing it on the pot cover 1, if the blocking piece 7 is not sealed in place, leakage will occur at the water outlet 28, prompting the user to adjust the blocking piece 7.

[0100] Specifically, such as Figure 15 As shown, the water flow switch 281 includes a push rod 2812 mounted on the sealing member 7, a first sealing portion 2811 mounted on the top of the push rod 2812, and a first elastic member 2813 sleeved around the outer periphery of the push rod 2812. The first sealing portion 2811 is located within the water tank 2. The elastic force of the first elastic member 2813 causes the push rod 2812 to move downward, causing the first sealing portion 2811 to abut and seal against the rim of the water outlet 28. The pot lid 1 is also provided with a water outlet seat 4, and the trigger member includes a trigger rib 41 mounted on the water outlet seat 4. When the water tank 2 is mounted on the pot lid 1, the trigger rib 41 pushes the push rod 2812 upward, compressing the first elastic member 2813 and causing the first sealing portion 2811 to move upward, opening the water outlet 28.

[0101] Preferably, if Figure 16 As shown, a reflux switch 291 is provided at the return water port 29. The reflux switch 291 includes a second sealing portion 2911 and a second elastic member 2912 located above the second sealing portion 2911. The second sealing portion 2911 is located inside the water tank 2. In the initial state, the second elastic member 2912 pushes the second sealing portion 2911 downward, causing the second sealing portion 2911 to abut and seal against the rim of the return water port 29. During the water-cooling depressurization process, the coolant flow has a certain pressure. Under the action of the water pressure, the coolant pushes the second sealing portion 2911 upward, compressing the second elastic member 2912. The second sealing portion 2911 is separated from the rim of the return water port 29, and the return water port 29 is opened.

[0102] Specifically, the pot lid 1 is provided with a water return seat 5 for docking and communicating with the water return port 29. Both the water return seat 5 and the water outlet seat 4 are provided with a seal 6, and the seal 6 is provided with a barrier portion between the water outlet seat 4 and the water outlet 28, and between the water return seat 5 and the water return port 29, and a plurality of communication holes 61 are spaced apart on the barrier portion.

[0103] like Figure 3As shown, the pot cover 1 is further provided with a water pump 17 , which is arranged below the cover plate 3 , and the cover plate 3 is provided with an upwardly raised avoidance portion 31 corresponding to the water pump 17 .
