[0050] As a commonly used cooking appliance, electric pressure cookers are increasingly widely used in various cooking scenarios due to their advantages such as fast cooking and good cooking results.

[0051] During the cooking process, sometimes it is necessary to add water to the cooking cavity. For example, when cooking meat or beans, the water in the cooking cavity evaporates quickly, and water needs to be added to the cooking cavity in time during the cooking process to help the meat or beans continue to stew; for another example, when stewing soup, such as stewing pig's trotters and cow's trotters, the soup evaporates quickly during the stewing process, and an appropriate amount of water needs to be added during the cooking process to maintain the flavor and richness of the soup.

[0052] However, in the related art, since the electric pressure cooker is in a high-pressure state during cooking, due to the effect of high pressure, when adding water, the user needs to first turn off the heating of the electric pressure cooker, then control the pressure relief valve to release the pressure in the cooking cavity, and then open the cover to add water to the cooking cavity after the pressure relief is completed. The water adding process is cumbersome. At the same time, this way of adding water also forces the food in the cooking cavity to reduce pressure and cool down during cooking, which makes the taste and flavor of the food worse; and after adding water and closing the cover, the cooking appliance needs to continue to heat and increase the pressure, which prolongs the cooking time of the food.

[0053] Therefore, in the related art, when the cooking cavity of the cooking appliance is in a high pressure state, there is a technical problem that it is difficult to inject water into the cooking cavity of the cooking appliance. The embodiment of the present application provides a cooking appliance that can at least solve the above technical problem to a certain extent.

[0054] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0055] The embodiment of the present application provides a cooking appliance 10. The cooking appliance 10 provided by the embodiment of the present application is capable of injecting water into the cooking cavity 300 when the cooking cavity 300 is in a high-pressure state.

[0056] like Figure 1As shown, the cooking utensil 10 includes a pot body 200 and a cover body 100, and the pot body 200 and the cover body 100 form a cooking cavity 300. The cooking cavity 300 is used to store food, and a heating device and the like are also provided in the pot body 200, which are used to heat the food in the cooking cavity 300 so as to cook the food in the cooking cavity 300. The pot body 200 includes a main body and a container, and the heating device and the like are installed on the main body, and the food is placed in the container, and the cover body 200 and the container form the cooking cavity 300. The pot body 200 can be a base, and the bottom of the container is placed on the base. The pot body 200 can also have a containing cavity, and the bottom of the container can be placed in the installation cavity, or all the containers can be contained in the containing cavity.

[0057] The cooking appliance 10 further includes a water injection module 400, such as Figure 2 As shown, the water injection module 400 includes a mounting seat 410 and a valve core member 420 . The mounting seat 410 is mounted on the pot body 200 or the cover body 100 . The mounting seat 410 has a flow channel 412 and a water inlet 413 and a water outlet 414 connected to the flow channel 412 . The water outlet 414 is located in the cooking cavity 300 .

[0058] It should be understood that the water inlet 413 of the water injection module 400 is used to communicate with the water source, so that the water source can enter the flow channel 412 through the water inlet 413 and then flow to the water outlet 414. The water outlet 414 is located in the cooking cavity 300, so that the water discharged from the water outlet 414 can enter the cooking cavity 300 to achieve the function of injecting water into the cooking cavity 300. Since the cover body 100 and the pot body 200 form the cooking cavity 300, the mounting seat 410 can be installed on both the pot body 200 and the cover body 100, which is not limited in the present application, as long as the water outlet 414 can be located in the cooking cavity 300 after installation.

[0059] The pot body 200 and the cover body 100 may be connected to form the cooking cavity 300. For example, after the cover body 100 is aligned with the pot body 200, it is rotated at a certain angle and snapped onto the pot body. For another example, one side of the cover body 100 is rotatably connected to one side of the pot body 200, and the other side of the cover body 100 is snap-connected to the other side of the pot body 200. The pot body 200 and the cover body 100 may also not be connected to form the cooking cavity 300. For example, the cover body 100 is directly placed on the pot body 200 to form the cooking cavity 300 with the pot body 200.

[0060] Specifically, the main body and the cover 100 may be connected to form a receiving cavity, and the container is placed in the receiving cavity. For example, after the cover 100 is aligned with the main body, it is rotated to a certain angle and snapped onto the main body. The cover 100 covers the container and forms a cooking cavity 300 with the container. For another example, one side of the cover 100 is rotatably connected to one side of the main body, and the other side of the cover 100 is snap-connected to the other side of the main body. The cover 100 and the main body and the container may also be unconnected, for example: the cover 100 directly covers the opening of the container and forms a cooking cavity 300 with the container. The mounting seat 410 is the mounting base of the valve core member 420, which can provide support and limit for the valve core member 420. The valve core member 420 of the water injection module 400 is installed in the flow channel 412. Under the action of the air pressure in the cooking cavity 300, the valve core member 420 can disconnect the water inlet 413 and the water outlet 414.

[0061] The water inlet 413 and the water outlet 414 are disconnected, which means that the water inlet 413 and the water outlet 414 are not connected. Under the action of the air pressure in the cooking cavity 300, the valve core 420 can block any one of the water inlet 413, the flow channel 412 or the water outlet 414, so that the water inlet 413 and the water outlet 414 are not connected, so that the gas in the cooking cavity 300 will not be discharged from the water inlet 413, so that the cooking appliance 10 can achieve the functions of pressurization and pressure maintenance; at the same time, when the cooking appliance 10 is cooking food, the food in the cooking cavity 300 will not or will be difficult to enter the water injection module 400, so as to avoid blockage of the water injection module 400 and ensure that the water injection function of the water injection module 400 can be achieved. When water is injected, under the action of water pressure, the water flow pushes the valve core 420 to move in the direction from the water inlet 413 to the water outlet 414. The water inlet 413 and the water outlet 414 are connected, so that the water flow entering the water inlet 413 can be discharged through the water outlet 414 and enter the cooking cavity 300.

[0062] The cooking utensil 10 of the present application can inject water into the cooking cavity 300 when the cooking cavity 300 is under pressure. When injecting water, there is no need to vent or reduce the pressure in the cooking cavity 300, nor is there any need to open the cover body 100. When injecting water, water can be injected through the water inlet 413, which simplifies the process of replenishing water during cooking of the cooking utensil 10, helps to ensure the taste of food, saves cooking time, and is convenient for users.

[0063] There are various ways for the valve core member 420 to disconnect the water inlet 413 and the water outlet 414, which are not limited in the present application.

[0064] For example, in some embodiments, the valve core 420 disconnects the water inlet 413 and the water outlet 414 by blocking the water inlet 413. Fig. 9As shown, the valve core member 420 is a spherical member, which is located in the flow channel 412. There is a gap between the flow channel 412 and the valve core member 420. Under the action of the air pressure in the cooking cavity 300, the valve core member 420 will move toward the water inlet 413 and block the water inlet 413, so that gas or food will not be discharged through the water inlet 413. When the air pressure in the cooking cavity 300 is low or water is injected, as shown in FIG. Fig.10 As shown, the valve core 420 moves downward under the action of gravity or water pressure, unblocking the water inlet 413, so that the water inlet 413 and the water outlet 414 are connected, so that the water injection function of the cooking cavity 300 can be realized.

[0065] For example, in some embodiments, the valve core 420 disconnects the water inlet 413 and the water outlet 414 by blocking the water outlet 414. Fig.11 As shown in FIG. 4 , the lower end of the valve core member 420 can extend out of the water outlet 414. Under the action of the air pressure in the cooking chamber 300, the lower end of the valve core member 420 will move toward the water outlet 414 until the lower end of the valve core member 420 blocks the water outlet 414, so that gas or food will not be discharged through the water inlet 413. When the air pressure in the cooking chamber 300 is low or water is injected, as shown in FIG. Fig.12 As shown, the valve core 420 moves downward under the action of gravity or water pressure, unblocking the water outlet 414, so that the water inlet 413 and the water outlet 414 are connected, so that the water injection function of the cooking cavity 300 can be realized.

[0066] For example, in some embodiments, the valve core 420 disconnects the water inlet 413 and the water outlet 414 by blocking the flow channel 412. Figure 2 , Figure 4 and Figure 5 As shown, the mounting seat 410 includes a valve seat 416 and a joint 417 connected to the valve seat 416, the water inlet 413 is arranged on the joint 417, the water outlet 414 is arranged on the valve seat 416, the flow channel 412 includes a first flow channel 4121 arranged in the joint 417 and a second flow channel 4122 in the valve seat 416, and the valve core 420 can block the first flow channel 4121 to disconnect the water inlet 413 and the water outlet 414. After such a design, the mounting seat 410 is composed of two parts connected by the valve seat 416 and the joint 417, and has a split structural design, which helps to simplify the processing technology and processing difficulty of the mounting seat 410. It should be understood that the first flow channel 4121 and the second flow channel 4122 are connected, so that the water entering the water inlet 413 flows into the first flow channel 4121, then enters the second flow channel 4122, and finally flows out from the water outlet 414. The connector 417 is used to connect to the connecting pipe 700 for transporting water flow.

[0067] The present application will hereinafter provide a specific explanation by taking the example of the valve core member 420 disconnecting the water inlet 413 and the water outlet 414 by blocking the first flow channel 4121 .

[0068] The connection between the valve seat 416 and the joint 417 is various, such as bonding, clamping, threaded connection, etc., which is not limited in this application. Figure 4 and Figure 5 As shown, an external thread is provided on the outer wall of the connector 417 near the valve seat 416, and an internal thread is provided on the inner wall of the second flow channel 4122 of the valve seat 416. The side of the valve seat 416 provided with the external thread is located in the second flow channel 4122 and is threadedly connected to the connector 417. The threaded connection method is not only convenient for connecting and disassembling the valve seat 416 and the connector 417, but also during the connection process, the bite of the thread will produce a certain sealing effect, so the sealing performance of the valve seat 416 and the connector 417 after connection can be guaranteed to a certain extent.

[0069] The valve core member 420 can be installed in the valve seat 416 or in the joint 417, which is not limited in the present application.

[0070] In some embodiments, Figure 2 As shown, the valve core member 420 is arranged in the valve seat 416. With such a design, the valve core member 420 is located in the second flow channel 4122 of the valve seat 416. When installing the valve core member 420, the valve core member 420 is first installed in the second flow channel 4122, and then the joint 417 is installed on the valve seat 416. Under the action of the joint 417, the valve core member 420 is limited in the valve seat 416.

[0071] In some embodiments, Figure 2 As shown, the valve core component 420 includes a first sealing component 422 and a valve core body 423 . The first sealing component 422 is installed on the valve core body 423 . The first sealing component 422 can block the first flow channel 4121 .

[0072] After such design, the valve core member 420 is composed of a first sealing member 422 and a valve core body 423, which is convenient for processing the valve core member 420, so that the first sealing member 422 and the valve core body 423 can be made of different materials, which helps the valve core member 420 to meet both the pressure-bearing requirements and the sealing performance requirements. The first sealing member 422 blocks the first flow channel 4121, so the first sealing member 422 can be made of a material with good sealing performance such as rubber; under the action of air pressure, the valve core member 420 will bear a certain amount of pressure, so the valve core body 423 can be made of a material with high strength and low density such as aluminum to ensure the strength of the valve core member 420, reduce the weight of the valve core member 420, and ensure that the valve core member 420 can float smoothly under the action of air pressure and block the first flow channel 4121.

[0073] There are various ways to connect the first sealing member 422 and the valve core body 423, such as bonding, clamping, etc., which are not limited here.

[0074] In some embodiments, the first sealing member 422 and the valve core body 423 are disposed in the second flow channel 4122 and are spaced apart from the second flow channel 4122. That is, there is a gap between the first sealing member 422 and the valve core body 423 and the inner wall of the second flow channel 4122, so that when the water injection module 400 is injected with water, the water flow can flow toward the water outlet 414 through the gap.

[0075] In some embodiments, the distance between the first seal 422 and the second flow channel 4122 is less than 2 mm. The first seal 422 is disposed in the second flow channel 4122. If the distance between the first seal 422 and the second flow channel 4122 is less than 2 mm, it means that the distance between the outer peripheral surface of the first seal 422 and the inner wall of the second flow channel 4122 is less than 2 mm, that is, the gap between the first seal 422 and the second flow channel 4122 is less than 2 mm. The larger the gap between the first seal 422 and the second flow channel 4122, the greater the flow rate of water during water injection, which is more helpful to improve the efficiency of water injection. However, if the gap between the first seal 422 and the second flow channel 4122 is too large, during the process of increasing the pressure of the cooking appliance 10, the gas will more easily overflow the cooking cavity 300 through the gap, making it difficult for the valve core 420 to move upward to block the first flow channel 4121 under the action of gas pressure. The distance between the first sealing member 422 and the second flow channel 4122 is less than 2 mm, which helps to ensure that the first sealing member 422 can smoothly block the first flow channel 4121 under the action of air pressure while ensuring that the water injection module 400 can inject water smoothly.

[0076] In some embodiments, the minimum gap between the valve core body 423 and the second flow channel 4122 is greater than 1 mm. Similarly, the valve core body 423 is disposed in the second flow channel 4122, and the minimum gap between the valve core body 423 and the second flow channel 4122 is greater than 1 mm, which means that the distance between the outer peripheral surface of the valve core body 423 and the inner wall of the second flow channel 4122 is greater than 1 mm, that is, the gap between the valve core body 423 and the second flow channel 4122 is greater than 1 mm. If the gap between the valve core body 423 and the second flow channel 4122 is too small, it will produce greater resistance to the water flow, reduce the water injection flow rate of the water flow, and thus reduce the water injection efficiency. The minimum gap between the valve core body 423 and the second flow channel 4122 is greater than 1 mm, which helps to ensure the efficiency of water injection of the water injection module 400. In some embodiments, under the condition that the valve core member 420 opens the water inlet 413 and the water outlet 414, the distance between the first sealing member 422 and the joint 417 is less than 2 mm. That is to say, when the water injection module 400 injects water, the first sealing member 422 moves toward the water outlet 414 under the action of water pressure to release the blockage of the first flow channel 4121. At this time, the maximum distance between the first sealing member 422 and the joint 417 is 2 mm. When the water injection module 400 injects water, the larger the distance between the first sealing member 422 and the joint 417, the greater the flow rate of water, which is more helpful to improve the efficiency of water injection. However, if the distance between the first sealing member 422 and the joint 417 is too large, after the water injection stops, the gas in the cooking cavity 300 will be more likely to overflow the cooking cavity 300 through the gap, making it difficult for the valve core member 420 to quickly move upward to block the first flow channel 4121 under the action of air pressure. The 2 mm spacing design here not only ensures the water injection efficiency during water injection, but also ensures that when the water injection stops, the valve core member 420 can quickly respond to the air pressure and quickly block the first flow channel 4121.

[0077] In some embodiments, Figure 2 As shown, the valve core member 420 also includes a reset member 424, which is connected to the valve core body 423 and the valve seat 416. The reset member 424 can be compressed when the water injection module 400 is injected with water, and the reset member 424 can provide the valve core member 420 with a restoring force to seal the first flow channel 4121.

[0078] That is to say, the reset member 424 can help the valve core member 420 to reset more quickly to block the first flow channel 4121. When water is injected, the valve core member 420 is affected by the impact of the water flow and will move toward the water outlet 414, thereby compressing the reset member 424, so that the water inlet 413 and the water outlet 414 are connected; when the water injection module 400 stops injecting water, the valve core member 420 is no longer affected by the impact of the water flow. Under the action of the restoring force of the reset member 424 (under the action of the reset member 424 restoring deformation), the valve core body 423 and the first sealing member 422 will be pushed toward the water inlet 413 to quickly block the first flow channel 4121.

[0079] With this design, under high pressure, the reset member 424 can assist the air pressure in blocking the first flow channel 4121 , thereby improving the performance of the valve core member 420 in blocking the first flow channel 4121 .

[0080] At the same time, after such a design, the valve core member 420 of the water injection module 400 is no longer limited to disconnecting the water inlet 413 and the water outlet 414 (i.e. blocking the first flow channel 4121) under the action of air pressure. The valve core member 420 of the water injection module 400 can also disconnect the water inlet 413 and the water outlet 414 (i.e. blocking the first flow channel 4121) under the action of the reset member 424, so that the valve core member 420 of the cooking utensil 10 can successfully block the first flow channel 4121 even if it is not under high pressure, so that the water injection module 400 can disconnect the water inlet 413 and the water outlet 414 in different cooking modes, thereby ensuring the stable operation of the cooking utensil 10.

[0081] The reset member 424 may be a spring, an elastic rubber block, etc., which is not limited in the present application.

[0082] In some embodiments, Figure 6 As shown, the valve core body 423 is provided with a resisting portion 4231, and the reset member 424 is in contact with the resisting portion 4231. The reset member 424 is resisted on the resisting portion 4231, so that a force is applied to the reset member 424 through the resisting portion 4231, or the force applied by the reset member 424 to the valve core body 423 is received through the resisting portion 4231.

[0083] In some embodiments, Figure 6 As shown, there are multiple abutting parts 4231, and the multiple abutting parts 4231 are arranged around the valve core body 423, and two adjacent abutting parts 4231 are arranged at intervals. After such a design, multiple abutting parts 4231 abut against the reset member 424 at the same time, so that the force applied by the reset member 424 to the valve core body 423 can be evenly distributed on each abutting part 4231, and the force applied by the valve core body 423 to the reset member 424 can be evenly distributed on the reset member 424 through the action of multiple abutting parts 4231, thereby avoiding uneven force on the valve core body 423 or the reset member 424 at a single point, and helping to ensure that the first sealing member 422 smoothly blocks the first flow channel 4121. Two adjacent abutting parts 4231 are arranged at intervals, so that water can flow through the gap between the two adjacent abutting parts 4231, reducing the resistance of the valve core body 423 to the water flow, and helping to improve the water injection efficiency of the water injection module 400.

[0084] In some embodiments, Figure 3As shown, a stop surface 4161 is provided in the second flow channel 4122, and the reset member 424 abuts against the stop surface 4161. The reset member 424 abuts against the stop surface 4161, and the stop surface 4161 provides support and limit for the reset member 424, so that the reset member 424 can smoothly reset the first sealing member 422 and the valve core body 423.

[0085] like Figure 3 and Figure 5 As shown, in some embodiments, the stop surface 4161 is an annular plane, located on the side of the valve seat 416 close to the water outlet 414 and below the abutting portion 4231. Figure 3 and Figure 6 As shown, in some embodiments, the reset member 424 is a spring, which is sleeved on the valve core body 423, with its upper end abutting against the supporting portion 4231 and its lower end abutting against the stop surface 4161, and the spring is always in a compressed state.

[0086] In some embodiments, at least a portion of the valve core body 423 is exposed at the water outlet 414, that is, at least a portion of the valve core body 423 extends out of the water outlet 414. In other words, the valve core body 423 always extends out of the water outlet 414, that is, when the first sealing member 422 blocks the first flow channel 4121 or when the water injection module 400 injects water, the valve core body 423 is partially exposed at the water outlet 414, so that the valve core body 423 can block part of the water outlet 414, which helps to prevent food in the cooking cavity 300 from entering the water outlet 414 and blocking the water outlet 414.

[0087] In some embodiments, Figure 6 As shown, the valve core body 423 is provided with a guide groove 4232, and the guide groove 4232 extends in the direction close to the water outlet 414. The number of guide grooves 4232 is not limited in this application, and can be one or more. On the one hand, the guide groove 4232 can guide the water flow so that the water flow can be discharged from the water outlet 414 more quickly; on the other hand, the design of the guide groove 4232 helps to increase the gap between the valve core body 423 and the second flow channel 4122, reduce the resistance of the water flow in the second flow channel 4122, and thus help to ensure the efficiency of water injection of the water injection module 400.

[0088] In some embodiments, the valve core 420 has a push surface 426 , and when the water injection module 400 is injecting water, the push surface 426 can move toward the water outlet 414 to push impurities in the flow channel 412 out of the water outlet channel 131 from the water outlet 414 .

[0089] When the cooking device 10 is in use, the food in the cooking cavity 300 will inevitably enter the flow channel 412, causing the flow channel 412 to be blocked, thus affecting the efficiency of water injection. After the push-out surface 426 is provided, under water injection conditions, the valve core 420 will move toward the water outlet 414 under the action of water pressure, and the push-out surface 426 thereon will also move toward the water outlet 414, thereby pushing the food in the flow channel 412 out of the water outlet 414, thus eliminating the situation where the food blocks the flow channel 412 to a certain extent, and ensuring the efficiency of water injection of the water injection module 400.

[0090] In some embodiments, when the water injection module 400 is injecting water, the valve core body 423 can at least partially extend out of the water outlet 414. It should be understood that the valve core body 423 can at least partially extend out of the water outlet 414 in the following two situations:

[0091] 1. The valve core body 423 always extends out of the water outlet 414, that is, when the first sealing member 422 blocks the first flow channel 4121, the valve core body 423 is partially exposed at the water outlet 414. When the water injection module 400 is injecting water, the valve core body 423 continues to extend out of the water outlet 414 under the action of water pressure.

[0092] 2. If Figure 2 As shown, when the water injection module 400 is water-injected, the valve core body 423 extends out of the water outlet 414. Figure 3 As shown, when the water injection module 400 is not injected with water, the valve core body 423 is not exposed at the water outlet 414 .

[0093] In the first case, the valve core body 423 always extends out of the water outlet 414, so that the valve core body 423 can block part of the water outlet 414, which helps to prevent the food in the cooking cavity 300 from entering the water outlet 414 and blocking the water outlet 414. In the second case, the water injection module 400 extends out of the water outlet 414 only when water is injected, so that the food in the water outlet 414 can be pushed out during the water injection process, and the water outlet 414 is unblocked, which helps to smoothly realize the water injection function.

[0094] In some embodiments, Figure 2 and 6 As shown, the push-out surface 426 includes a first push-out surface 4261 and / or a second push-out surface 4262, the first push-out surface 4261 is arranged around the outer peripheral wall of the valve core member 420, and the second push-out surface 4262 is the end surface of the valve core member 420 facing the water outlet 414. In other words, the push-out surface 426 may have only the first push-out surface 4261, or only the second push-out surface 4262, or both the first push-out surface 4261 and the second push-out surface 4262.

[0095] The first push-out surface 4261 may be a circumferential surface, which is disposed on the outer peripheral wall of the valve core member 420 in an axial ring around the valve core member 420. The first push-out surface 4261 may also be provided with a plurality of Figure 6 As shown in FIG. 1 , a plurality of first push-out surfaces 4261 are arranged on the outer peripheral wall of the valve core member 420 around the axial spacing ring of the valve core member 420. The plurality of first push-out surfaces 4261 work together to push the impurities located in the flow channel 412 and in the circumferential direction of the valve core member 420. The second push-out surface 4262 is the end surface of the valve core member 420 facing the water outlet 414, as shown in FIG. Figure 6 As shown, that is, the lower end surface of the valve core 420, the second push surface 4262 pushes out the impurities below the second push surface 4262. The cooperation between the first push surface 4261 and the second push surface 4262 helps to push out all the impurities in the flow channel 412.

[0096] In some embodiments, the first push surface 4261 is tilted, and along the direction of water flow, the axial distance between the first push surface 4261 and the valve core member 420 gradually decreases. Figure 6 When the water injection module 400 is injecting water, the valve core 420 moves along the direction of the water flow under the action of the water flow, thereby driving the first push surface 4261 to move along the direction of the water flow. Since the first push surface 4261 is designed to be inclined, when the first push surface 4261 moves along the direction of the water flow, the distance between the first push surface 4261 and the water outlet 414 gradually decreases, so that impurities around the valve core 420 are gradually pushed out, which helps to improve the degree of circumferential cleanliness of the valve core 420.

[0097] In some embodiments, the projection of the pushing surface 426 in the direction of the water outlet 414 at least partially overlaps with the water outlet 414, so that impurities in the flow channel 412 can be smoothly pushed out from the water outlet 414, ensuring the cleaning effect.

[0098] In some embodiments, Figure 3 As shown, the mounting seat 410 is mounted on the cover 100, and the water injection module 400 includes a second sealing member 430, which is sleeved on the mounting seat 410 to seal the gap between the mounting seat 410 and the cover 100. The second sealing member 430 is provided so that the water injection module 400 and the cover 100 are tightly connected, thereby ensuring the airtightness of the cooking cavity 300. At the same time, after such a design, when the pressure in the cooking cavity 300 exceeds the safe pressure, the second sealing member 430 can be deformed, so that a gap is generated between the second sealing member 430 and the cover 100, so as to relieve the pressure and exhaust the cooking cavity 300, thereby avoiding excessive pressure and explosion of the pressure cooker, and effectively ensuring the safety of the cooking device 10.

[0099] In some embodiments, a spring sheet 440 is further disposed above the second sealing member 430, and a spring washer 450 is disposed below the second sealing member 430. The spring sheet 440 and the spring washer 450 are both sleeved on the mounting seat 410, and the second sealing member 430 is located between the spring sheet 440 and the spring washer 450. Under the action of the spring washer 450, the upper end surface of the spring sheet 440 abuts against the mounting seat 410, and the lower end surface abuts against the second sealing member 430. The lower end of the spring washer 450 abuts against the mounting seat 410, and the upper end abuts against the second sealing member 430. In some embodiments, such as Figure 7 As shown, the cooking appliance 10 further includes a water tank 500, a water pump 600 and a connecting pipe 700. The connecting pipe 700 connects the water tank 500 and the water inlet 413 of the water injection module 400, and the water pump 600 is installed on the water tank 500 or the connecting pipe 700. Through the design of the water tank 500, the water pump 600 and the connecting pipe 700, the cooking appliance 10 can store water through the water tank 500, pump the water in the water tank 500 into the water inlet 413 through the water pump 600, and then discharge it from the water outlet 414, so that the functions of the cooking appliance 10 are more diverse, which is helpful for users to use the cooking appliance 10.

[0100] In some embodiments, Figure 8 As shown, the cover body 100 includes a cover body 140 and a cover assembly 110, and the cover assembly 110 includes a cover body 120 and a handle 130. The cover body 140 is installed on the cover body 140, and the handle 130 is installed on the cover body 120. The handle 130 has a water outlet channel 131, and the water outlet 414 is connected to the water outlet channel 131. After such a design, when water needs to be injected during the cooking process, the water discharged from the water outlet 414 enters the water outlet channel 131 of the handle 130, and then is discharged into the cooking cavity 300 through the water outlet channel 131, so that the water flow can pass through the handle 130 and be injected into the cooking cavity 300. The handle 130 integrates the functions of holding and injecting water at the same time, which helps to simplify the structure of the cover body 100. The operator can install or remove the cover assembly 110 by holding the handle 130. In some embodiments, such as Figure 5 and Figure 8 As shown, the mounting seat 410 has a clamping portion 411, which is installed in the water outlet channel 131 and clamped with the inner wall of the water outlet channel 131. When the cover plate assembly 110 needs to be installed, the handle 130 is held and the water outlet channel 131 is clamped outside the clamping portion 411; when the cover plate assembly is disassembled, the handle 130 is held and the water outlet channel 131 is pulled out from the clamping portion 411.

[0101] like Figure 5 As shown, in some embodiments, the clamping portion 411 protrudes from the peripheral wall of the mounting seat 410 , and the size of the clamping portion 411 is larger than the cross-sectional size of the water outlet channel 131 so that the clamping portion 411 can be clamped in the water outlet channel 131 .

[0102] The working principle of the cooking device 10 of the present application is introduced as follows:

[0103] like Figure 3 As shown, during the cooking process of the cooking utensil 10, the first sealing member 422 on the valve core member 420 will abut against the lower end surface of the joint 417 under the action of the reset member 424 or the combined action of the reset member 424 and the air pressure in the cooking cavity 300, thereby blocking the first flow channel 4121 and preventing the food, water, gas, etc. in the cooking cavity from being discharged through the first flow channel 4121, thereby ensuring the smooth cooking of the food.

[0104] like Figure 2 As shown, when the cooking cavity 300 needs to be filled with water, the water pump 600 works to pump the water in the water tank 500 into the connecting pipe 700, and then enters the first flow channel 4121 through the water inlet 413. The water flow has water pressure, which will exert a downward force on the first sealing member 422, driving the valve core member 420 to move downward to release the blockage of the first sealing member 422, and the water flow will enter the second flow channel 4122 through the first flow channel 4121, and finally be discharged from the water outlet 414. During the water filling process, the valve core member 420 moves downward and extends out of the water outlet 414 to push out the food and other impurities blocked in the second flow channel 4122 to ensure smooth water flow.

[0105] When the cooking chamber 300 is filled with water, the water pump 600 stops working. At this time, the water flow no longer applies a downward force to the first sealing member 422. The first sealing member 422 will abut against the lower end surface of the joint 417 under the action of the reset member 424 or the combined action of the reset member 424 and the air pressure in the cooking chamber 300, thereby blocking the first flow channel 4121.

[0106] To summarize, in the cooking utensil 10 provided in the embodiment of the present application, under the action of the air pressure in the cooking cavity 300, the valve core member 420 can block any one of the water inlet 413, the flow channel 412 or the water outlet 414, so that the water inlet 413 and the water outlet 414 are not connected, so that the gas in the cooking cavity 300 will not be discharged from the water inlet 413, so that the cooking utensil 10 can achieve the functions of pressurization and pressure maintenance; at the same time, when the cooking utensil 10 is cooking food, the food in the cooking cavity 300 will not or will be difficult to enter the water injection module 400, so as to avoid blockage of the water injection module 400 and ensure that the water injection function of the water injection module 400 can be achieved. When water is injected, under the action of water pressure, the water flow pushes the valve core 420 to move, so that the water inlet 413 and the water outlet 414 are connected in the direction from the water inlet 413 to the water outlet 414, so that the water flow entering the water inlet 413 can be discharged through the water outlet 414 and enter the cooking cavity 300. The cooking utensil 10 of the present application can inject water into the cooking cavity 300 under the condition that the cooking cavity 300 has pressure. When injecting water, there is no need to exhaust or reduce the pressure of the cooking cavity 300, and there is no need to open the cover 100. When injecting water, the water flow can be injected through the water inlet 413, which simplifies the process of replenishing water in the middle of cooking of the cooking utensil 10, helps to ensure the taste of food, saves cooking time, and is convenient for users.
