DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0039] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0041] With the advancement of technology, the functions of cooking utensils are becoming more and more perfect. In some usage scenarios, it is necessary to add water to the cooking cavity during cooking. For example, when cooking meat or beans, the water in the cooking cavity evaporates quickly, and it is necessary to add water to the cooking cavity in time during cooking 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 cooking to maintain the flavor and richness of the soup. In some usage scenarios, water is added to the cooking cavity before cooking. For example, some cooking utensils have a timed cooking function. The user puts the food to be cooked into the cooking cavity in advance, and then sets the cooking time through the control panel on the cooking appliance. When the set time is reached, the cooking appliance automatically fills water into the cooking cavity, and then turns on the heating device to heat and cook.

[0042] The cooking device is provided with a water outlet connected to the cooking cavity, so that water flow outside the cooking cavity can be successfully added into the cooking cavity.

[0043] However, as cooking progresses, the food and water in the cooking chamber are in a boiling state, and rice, seaweed and other foods can easily enter the flow channel through the water outlet, causing the flow channel to be blocked, resulting in a smaller amount of water out of the water outlet, or the flow channel is completely blocked and the water outlet cannot discharge water at all. In addition, food residues in the flow channel are prone to spoilage and odor, affecting the use. In the related art, users usually use tools such as wire to clean and dredge the flow channel, which is cumbersome to clean and inconvenience to users.

[0044] Therefore, in the related art, the cooking utensils have the technical problem that the flow channel is blocked and it is inconvenient to clean. The embodiment of the present application provides a cooking utensil, which can at least solve the above technical problem to a certain extent.

[0045] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0046] The embodiment of the present application provides a cooking utensil 10. The cooking utensil 10 provided in the embodiment of the present application can push out impurities in a flow channel when water is injected, thereby clearing the flow channel.

[0047] like Figure 1 As 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.

[0048] The pot body 200 includes a main body and a container, a heating device and other structures are installed on the main body, food is placed in the container, and the cover 200 and the container form a 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 accommodating cavity, and the bottom of the container can be placed in the installation cavity, or all the containers can be accommodated in the accommodating cavity.

[0049] 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 200. 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.

[0050] 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 at 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, 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.

[0051] The cooking appliance 10 further includes a water injection module 400, such as Figure 2As 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. The mounting seat 410 is the mounting base of the valve core member 420, and can provide support and limit for the valve core member 420.

[0052] 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.

[0053] The valve core 420 is installed in the flow channel 412 and has a push surface 426. When the water injection module 400 is injected with 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.

[0054] During the use of the cooking device 10, the food in the cooking cavity 300 will inevitably enter the flow channel 412 through the water outlet 414, causing the flow channel 412 to be blocked, affecting the efficiency of water injection. After the push-out surface 426 is set, when the water injection module 400 is injected with water, the valve core 420 will be affected by the water flow and move toward the water outlet 414, thereby driving the push-out surface 426 thereon to move toward the water outlet 414, and then the food in the flow channel 412 can be pushed out from the water outlet 414, which to a certain extent eliminates the situation where the food blocks the flow channel 412, ensures the efficiency of water injection of the water injection module 400, and ensures the hygiene of the cooking device 10. After such a design, the valve core 420 is automatically driven by the water flow to push out the push-out surface 426 to clean the flow channel 412, and there is no need to manually clean the water injection module 400 with tools. The cooking device 10 can be automatically cleaned, which is more convenient and more efficient.

[0055] In some embodiments, at least a portion of the valve core member 420 is exposed at the water outlet 414, that is, at least a portion of the valve core member 420 extends out of the water outlet 414. In other words, the valve core member 420 always extends out of the water outlet 414, that is, when the water injection module 400 injects water or when the water injection module 400 does not inject water, the valve core member 420 is partially exposed at the water outlet 414, so that the valve core member 420 can block a portion of the water outlet 414, which helps to prevent the food in the cooking cavity 300 from entering the flow channel 412 through the water outlet 414 and blocking the flow channel 412.

[0056] In some embodiments, when the water injection module 400 is injecting water, at least a portion of the valve core member 420 can extend from the flow channel 412 to the outside of the water outlet 414. It should be understood that at least a portion of the valve core member 420 can extend from the flow channel 412 to the outside of the water outlet 414 in the following two situations:

[0057] 1. The valve core 420 always extends out of the water outlet 414, that is, when the water injection module 400 injects water, the valve core 420 is partially exposed at the water outlet 414; when the water injection module 400 injects water, the valve core 420 continues to extend out of the water outlet 414 under the action of water pressure.

[0058] 2. If Figure 2 As shown, when the water injection module 400 is water-injected, the valve core 420 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 member 420 is not exposed at the water outlet 414. When the water injection module 400 is injected with water, the valve core member 420 partially extends out of the water outlet 414, which helps to push all the food remaining in the flow channel 412 out of the flow channel 412 through the water outlet 414, helps to ensure the self-cleaning effect of the valve core member 420, and helps to ensure the smooth realization of the water injection function.

[0059] 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.

[0060] 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 6As shown, in some embodiments, four first push-out surfaces 4261 are provided. Multiple first push-out surfaces 4261 are provided on the outer peripheral wall of the valve core member 420 around the axial spacing ring of the valve core member 420. Multiple first push-out surfaces 4261 work together to push 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, the second push surface 4262 pushes out the impurities below the second push surface 4262, that is, the lower end surface of the valve core 420. 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, ensuring the self-cleaning effect of the valve core 420.

[0061] 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.

[0062] 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.

[0063] In some embodiments, Figure 6 As shown, a plurality of first push-out surfaces 4261 are provided, and the plurality of first push-out surfaces 4261 are provided on the outer peripheral wall of the valve core member 420 around the axial spacing ring of the valve core member 420; on the valve core member 420, a guide groove 4232 is opened between two adjacent first push-out surfaces 4261, and the guide groove 4232 extends toward the direction close to the water outlet 414.

[0064] That is, around the axial direction of the valve core 420, the first push surface 4261 and the guide groove 4232 are arranged in sequence in the manner of first push surface 4261-guide groove 4232-first push surface 4261-guide groove 4232. This design helps to ensure the circumferential cleaning effect of the valve core 420 while ensuring the flow rate of water injection of the water injection module 400.

[0065] After such design, the number of the first push-out surface 4261 and the guide groove 4232 is the same, and the number of the first push-out surface 4261 and the guide groove 4232 is not limited in this application. 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 420 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.

[0066] The second pushing surface 4262 may be a curved surface, which is not limited in the present application.

[0067] In some embodiments, such as Figure 2 and Figure 6 As shown, the second push surface 4262 is a plane and perpendicular to the axis of the flow channel 412. After such a design, since the second push surface 4262 is a plane and perpendicular to the axis of the flow channel 412, when pushing, the entire second push surface 4262 can more comprehensively contact and act on the blockage, the thrust is more concentrated, and the cleaning effect is better.

[0068] In some embodiments, Figure 2 As shown, the valve core member 420 includes a first sealing member 422 installed in the flow channel 412, a valve core body 423 and a reset member 424. The first sealing member 422 is installed on the valve core body 423, and the reset member 424 is connected to the valve core body 423 and the mounting seat 410. The reset member 424 can be compressed under the condition of water injection module 400, and the reset member 424 can provide the first sealing member 422 with a restoring force to seal the first flow channel 4121, so as to disconnect the water inlet 413 and the water outlet 414.

[0069] 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. With this design, when the water injection module 400 is not filled with water, under the action of the reset member 424, the valve core body 423 drives the first sealing member 422 to press against the mounting seat 410, so that the first flow channel 4121 is sealed, thereby disconnecting the water inlet 413 and the water outlet 414.

[0070] In this way, when the cooking utensil 10 is cooking food, due to the sealing effect of the first sealing component 422, the food in the cooking cavity 300 will not or will hardly enter the water injection module 400, thereby avoiding blockage and contamination of the water injection module 400 to a certain extent, ensuring that the water injection function of the water injection module 400 can be realized, and also ensuring the cleanliness and hygiene of the water injection module 400; in this way, when the cooking utensil is a high-pressure cooking utensil, due to the sealing effect of the first sealing component 422, 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.

[0071] When the water injection module 400 is injecting water, under the action of water pressure, the water flow pushes the first sealing component 422 and the valve core body 423 to move and the reset component 424 to compress, so that there is a gap between the first sealing component 422 and the flow channel 412, 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, thereby entering the cooking cavity 300 and realizing the water injection function.

[0072] In summary, after such design, the cooking utensil 10, through the action of the valve core member 420, makes the flow channel 412 in a normally closed state, thereby ensuring the smooth realization of the pressurization and pressure-maintaining functions of the cooking utensil, so that the food in the cooking cavity 300 will not or is difficult to enter the water injection module 400, and to a certain extent, avoids the blockage and pollution of the water injection module 400, ensures that the water injection function of the water injection module 400 can be realized, and also ensures the cleanliness and hygiene of the water injection module 400; at the same time, under the action of the water flow, the water inlet 413 and the water outlet 414 are in a connected state, so that the cooking utensil 10 of the present application can inject water into the cooking cavity under pressure conditions, and when injecting water, there is no need to exhaust or reduce the pressure of the cooking cavity 300, nor is there any need to open the cover body 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 the food, saves cooking time, and is convenient for users to use.

[0073] The valve core member 420 includes a first sealing member 422 and a valve core body 423, which can facilitate the processing of 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 to make the valve core member 420 meet both the pressure bearing requirements and the sealing performance requirements. Specifically, the first sealing member 422 seals 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 the reset member 424 and the air pressure in the cooking cavity 300, the valve core member 420 will bear a certain force, 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, while reducing the weight of the valve core member 420, ensuring that the valve core member 420 can smoothly move upward under the action of the reset member 424 and drive the first sealing member 422 to block the flow channel 412.

[0074] 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.

[0075] In some embodiments, Figure 2 , Figure 4 and Figure 5As 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, and 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; the valve core member 420 is arranged in the second flow channel 4122 of the valve seat 416, the reset member 424 is connected to the valve core body 423 and the valve seat 416, and the first sealing member 422 can seal the first flow channel 4121 to disconnect the water inlet 413 and the water outlet 414.

[0076] After such design, the mounting seat 410 is composed of two parts, the valve seat 416 and the joint 417, which are connected and formed in a split structural design, which helps to simplify the processing technology and processing difficulty of the mounting seat 410. After such design, 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. 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 joint 417 is used to connect with the connecting pipe 700 for transporting water flow.

[0077] 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.

[0078] It should be noted that when the first seal 422 and the valve core body 423 are arranged in the second flow channel 4122, there is a gap between the first seal 422, the valve core body 423 and the second flow channel 4122, so that when the water injection module 400 is injected with water, the water flow can flow through the gap toward the water outlet 414, thereby successfully realizing the function of injecting water into the cooking cavity 300.

[0079] In some embodiments, the minimum gap between the valve core body 423 and the second flow channel 4122 is greater than 1 mm. The valve core body 423 is disposed in the second flow channel 4122. If the minimum gap between the valve core body 423 and the second flow channel 4122 is greater than 1 mm, it means that the distance between the outer circumferential 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 in the circumferential direction 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.

[0080] In some embodiments, when the valve core 420 opens the water inlet 413 and the water outlet 414, the distance between the first seal 422 and the joint 417 is less than 2 mm. That is, when the water injection module 400 injects water, the first seal 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 seal 422 and the joint 417 is 2 mm. When the water injection module 400 injects water, the larger the distance between the first seal 422 and the joint 417, the smaller the resistance to the water flow, the larger the flow rate of the water flow, and the more helpful it is to improve the efficiency of water injection. However, if the distance between the first seal 422 and the joint 417 is too large, after the water injection stops, the first seal 422 takes a long time to reset and block the first flow channel 4121 under the action of the reset member, and the gas, food, etc. in the cooking cavity 300 can easily overflow the cooking cavity 300 through the gap between the first seal 422 and the joint 414. The 2 mm spacing design here not only ensures the water injection efficiency during water injection, but also ensures that when the water injection is stopped, the valve core member 420 can be quickly reset under the action of the reset member 424 to quickly block the first flow channel 4121.

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

[0082] The spring has good elasticity and low cost, such as 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. Along the expansion and contraction direction of the spring, one side of the spring abuts against the valve core body 423, and the other side abuts against the valve seat 416. Figure 2 As shown, the upper end of the spring abuts against the valve core body 423 , and the lower end abuts against the valve seat 416 .

[0083] In some embodiments, Figure 6As shown, the valve core body 423 is provided with a resisting portion 4231, and the spring abuts against the resisting portion 4231. The spring abuts against the resisting portion 4231 to apply a force to the reset member 424 through the resisting portion 4231, or to withstand the force applied by the spring to the valve core body 423 through the resisting portion 4231.

[0084] 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 spring at the same time, so that the force applied by the spring 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 spring can be evenly distributed on the spring through the action of multiple abutting parts 4231, thereby avoiding uneven force on the valve core body 423 or the spring 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.

[0085] In some embodiments, Figure 6 As shown in FIG. 4 , the gap between two adjacent abutting portions 4231 and the guide groove 4232 between adjacent first pushing surfaces 4261 are aligned along the flow direction of the water flow. Figure 6 As shown, four abutting portions 4231 are provided to form four gaps, and four first pushing surfaces 4261 are provided to form four guide grooves 4232. In the vertical direction, the four gaps are respectively aligned with the four guide grooves 4232. This design allows water to directly enter the guide groove 4232 after passing through the gap between two adjacent abutting portions 4231, which helps to reduce the resistance of the valve core body 423 to the water flow and improve the efficiency of water injection of the water injection module.

[0086] In some embodiments, Figure 3 As 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 spring abuts against the stop surface 4161, and the stop surface 4161 provides support and limitation for the spring, so that the reset member 424 can smoothly reset the first sealing member 422 and the valve core body 423.

[0087] like Figure 3 and Figure 5 As shown, in some embodiments, the stop surface 4161 is an annular plane, located on a side of the valve seat 416 close to the water outlet 414 and below the abutting portion 4231 .

[0088] In some embodiments, 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.

[0089] 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.

[0090] In some embodiments, Figure 3 As shown, a spring sheet 440 is further arranged above the second sealing member 430, and a spring washer 450 is arranged below the second sealing member 430. Both the spring sheet 440 and the spring washer 450 are 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, 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.

[0091] In some embodiments, Figure 8As 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.

[0092] 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 .

[0093] The working principle of the cooking device 10 of the present application is introduced as follows:

[0094] 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, under the action of the reset member 424, abut against the lower end surface of the joint 417, blocking the first flow channel 4121, 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.

[0095] 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. The water flows through the first flow channel 4121 into the second flow channel 4122, and finally discharges from the water outlet 414. During the water injection process, the valve core member 420 drives the push-out surface 426 thereon to move downward and extend 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.

[0096] When the cooking chamber 300 is filled with water, the water pump 600 stops working. At this time, the water flow no longer exerts a downward force on 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 to block the first flow channel 4121.

[0097] See also Fig. 9 As shown, based on the same inventive concept, the embodiment of the present application also provides a water injection device cleaning method, which can control the water pump 600 to run intermittently to flush out the blockage in the water outlet 414. The water injection device cleaning method provided in the embodiment of the present application is applied to the above-mentioned cooking utensil 10.

[0098] The water injection device cleaning method comprises the following steps:

[0099] Step S100, obtaining a cleaning instruction.

[0100] The cleaning instruction indicates that the current flow channel 412 or the water outlet 414 is blocked, and the flow channel 412 or the water outlet 414 needs to be cleaned and unblocked.

[0101] The cleaning instruction may be triggered by the user or automatically by the cooking appliance 10 .

[0102] Among them, for user triggering, the user can observe the blockage of the flow channel 412 and the water outlet 414 of the water injection module 400, and when it is found that the flow channel 412 and the water outlet 414 have food residue or blockage and need to be cleaned, the user can click the cleaning button on the control panel of the cooking appliance 10 to trigger the cleaning instruction. Of course, it is not limited to clicking the cleaning button on the control panel to trigger the cleaning instruction. For example, some cooking utensils 10 are equipped with a remote control panel, and the user can also click the cleaning button on the remote control panel to trigger the cleaning instruction. For another example, some cooking utensils 10 have an Internet connection function and can be connected to mobile phones, tablets, computers and other devices. The user can click the cleaning function on these devices to trigger the cleaning instruction.

[0103] The cooking appliance 10 may be automatically triggered by automatically detecting the blockage of the flow channel 412 and the water outlet 414. When the flow channel 412 is detected to be blocked and needs to be unblocked or cleaned, the cleaning instruction is automatically triggered. The following examples are provided for illustration:

[0104] Example 1: In some embodiments, the temperature value in the cooking cavity 300 is obtained. If the temperature value in the cooking cavity 300 is greater than or equal to the dry-boiling temperature value of the cooking appliance 10, a cleaning instruction is triggered.

[0105] When no water is added to the cooking cavity 300 of the cooking device 10 or the amount of water added does not meet the requirement, the temperature in the cooking cavity 300 will rise rapidly due to the lack of heat absorption by evaporation of water.

[0106] If the temperature exceeds the dry-boiling temperature value, it means that there is no water in the cooking cavity 300, and the flow channel 412 or the water outlet 414 is blocked, resulting in the water injection device not injecting enough water into the cooking cavity 300 or the water injection device not injecting water at all. Therefore, when the temperature value of the cooking cavity 300 is greater than or equal to the dry-boiling temperature value of the cooking device 10, the cleaning instruction can be automatically triggered to make the water pump 600 intermittently run a set number of times to dredge the flow channel 412 or the water outlet 414 of the water injection module 400.

[0107] The dry-boiling temperature value of the cooking utensil 10 is different according to the type and size of the cooking utensil 10, and the user can design it according to the adaptability of the specific cooking utensil 10. Generally speaking, when the cooking utensil 10 is an electric pressure cooker, its dry-boiling temperature value is generally set to 120°C-150°C.

[0108] In some embodiments, if the temperature value in the cooking cavity 300 is greater than or equal to the dry-burning temperature value of the cooking utensil 10, the heating to the cooking cavity 300 is stopped. That is, when the temperature value in the cooking cavity 300 is greater than or equal to the dry-burning temperature value of the cooking utensil 10, the cleaning instruction is triggered and the heating of the cooking utensil 10 is stopped at the same time to avoid the melting of the inner pot and the burning of food, so as to improve the safety of the cooking utensil 10.

[0109] Example 2: In some embodiments, the operating current of the water pump 600 is obtained when the water pump 600 is running; if the operating current of the water pump 600 is greater than the set current, the cleaning instruction is triggered.

[0110] When the water injection device is not blocked, the operating current of the water pump 600 is usually stable. When the water injection device is blocked, the resistance encountered by the water flow increases. In order to overcome this resistance, the water pump 600 needs to consume more energy, so the current will become larger. Therefore, when the operating current of the water pump 600 is greater than the set current, it means that the flow channel 412 or the water outlet 414 is blocked and needs to be unblocked and cleaned, thus triggering the cleaning instruction. The set current value is related to the structure of the water injection device, etc. The user can set it adaptively according to the specific situation.

[0111] In some embodiments, the cleaning current of the water pump 600 is set to be greater than the operating current during cleaning. That is, if the operating current of the water pump 600 is greater than the set current, the cleaning instruction will be triggered. During cleaning, the cleaning current of the water pump 600 is greater than the operating current, so that the pressure of the water flow increases, thereby increasing the impact force of the water flow on the valve core 420, so that the valve core 420 can drive the push surface 426 thereon to move along the direction of the water flow, so as to push the obstruction in the flow channel 412 or the water outlet 414 out of the water outlet 414.

[0112] Generally, the more serious the blockage of the flow channel 412 or the water outlet 414 is, the greater the operating current of the water pump 600 is. Therefore, the cleaning current of the water pump 600 can be matched according to the operating current of the water pump. In other words, the more serious the blockage is, the greater the cleaning current of the water pump 600 is, so that the water flow pressure is greater, so that the impact force of the water flow on the valve core 420 is greater, so as to dredge the blockage in the flow channel 412 or the water outlet 414.

[0113] For example, if the current is set to 0.5A, if the working current of the water pump 600 is 0.5-1A at this time, the flow channel 412 or the water outlet 414 is blocked and the blockage is not serious, then the cleaning current of the water pump 600 when cleaning is 2A; if the working current of the water pump 600 is 1-2A at this time, then the flow channel 412 or the water outlet 414 is blocked and the blockage is relatively serious, then the cleaning current of the water pump 600 when cleaning is 3A; if the working current of the water pump 600 is greater than 2A at this time, then the flow channel 412 or the water outlet 414 is seriously blocked, then the cleaning current of the water pump 600 when cleaning is 5A.

[0114] Step S200, controlling the water pump 600 to intermittently run a set number of times according to the cleaning instruction.

[0115] The intermittent operation of the water pump 600 means that within a certain time interval, the water pump 600 runs for a first preset time and then stops for a second preset time, and then runs for the first preset time and then stops for the second preset time, and repeats this process. When the cleaning instruction is obtained, the water pump 600 is controlled to run intermittently until it runs for a set number of times.

[0116] The water pump 600 is operated intermittently for multiple times, so that the water flow intermittently impacts the obstruction. The intermittent impact mode makes the water flow alternate between impact and stillness, which can effectively use the vibration of water to loosen the obstruction in the flow channel 412, so that the obstruction is flushed out by the water flow, and then the water injection module 400 is unblocked, which helps to improve the flow rate of water injection of the water injection module 400, thereby ensuring the efficiency of water injection of the water injection module 400, and at the same time helps to ensure the hygiene of the cooking utensil 10. At the same time, the valve core member 420 will move toward the direction of the water outlet 414 under the impact of the water flow, compressing the reset member 424; when the water injection module 400 stops injecting water, the valve core member 420 is no longer impacted by the water flow, and under the action of the restoring force of the reset member 424, the reset member 424 will push the valve core member 420 to move toward the direction of the water inlet 413, so that the valve core member 420 returns to the initial state, that is, the position before water injection. In this way, the intermittent operation of the water pump 600 will drive the water to be pumped out intermittently, thereby causing the valve core member 420 to reciprocate in the flow channel 412 under the action of the water flow and the reset member 424 . The reciprocating movement of the valve core member 412 drives the first pushing surface 4261 and the second pushing surface 4262 thereon to also reciprocate, thereby loosening the blockage in the flow channel 412 or the water outlet 414. The first pushing surface 4261 continuously pushes out the blockage in the circumferential direction of the valve core member 412, and the second pushing surface 4262 continuously pushes out the blockage located on the side of the second pushing surface 4262 facing the water outlet 414. The first pushing surface 4261 and the second pushing surface 4262 cooperate with each other to push out all the impurities in the flow channel 412 and the water outlet 414, thereby effectively loosening the blockage in the flow channel 412, and at the same time continuously pushing out the impurities in the flow channel 412 from the water outlet 414. In addition, the flow of water causes the blockage to be flushed out, thereby cleaning and unblocking the flow channel 412.

[0117] The first preset time is too short, which may cause the valve core member 420 to be unable to move toward the water outlet 414, or cause the valve core member 420 to move a short distance toward the water outlet 414, and fail to play the role of pushing out the blockage; the second preset time is too short, which may cause the valve core member 420 to reset a short distance.

[0118] Therefore, the first preset time and the second preset time affect the amplitude of the reciprocating motion of the valve core member 420. It is necessary to strictly control the first preset time for starting the water pump 600 and the second preset time for stopping so that the amplitude of the reciprocating motion of the valve core member 412 in the flow channel 412 meets the requirement of pushing out the blockage in the flow channel 412.

[0119] The specific values ​​of the first preset time and the second preset time are related to the power of the water pump 600, the cross-sectional area of ​​the flow channel 412, the size of the valve core component 420, etc. The first preset time and the second preset time are set according to the power of the water pump 600, the cross-sectional area of ​​the flow channel 412, the size of the valve core component 420, etc., to ensure that the amplitude of the reciprocating motion of the valve core component 412 in the flow channel 412 meets the requirement of pushing out the blockage in the flow channel 412.

[0120] In some embodiments, the valve core member 420 disconnects the water inlet 413 and the water outlet 414 under the combined action of the reset member 424 and the air pressure in the cooking cavity 300. At this time, the water pressure value of the water pump 600 should be greater than the air pressure in the cooking cavity 300 and the restoring force of the reset member 424. That is, the force exerted by the water flow on the valve core member 420 is greater than the combined force of the gas in the cooking cavity 300 and the reset member 424 on the valve core member 420, so that the water flow can smoothly push the valve core member 420 to move toward the water outlet 414, so that the water inlet 413 and the water outlet 414 are connected, so that the obstruction in the flow channel 412 can be pushed out by the valve core member 420.

[0121] Wherein, step S200 may include step S210 and step S220.

[0122] If the cooking device 10 is not used for a long time, the residual water in the connecting pipe 700 will deteriorate and smell, and the water contains a large number of bacteria, which will affect the use of the cooking device 10. The set number of intermittent operations of the water pump 600 can be determined according to the single water injection volume of the water injection module 400 and the total capacity of the connecting pipe 700, so that after the water pump 600 is intermittently operated for the set number of times, the residual water in the connecting pipe 700 can be completely pumped out.

[0123] like Fig.10 As shown, in some embodiments, determining the set number of intermittent operations of the water pump 600 includes the following steps:

[0124] S210, calculating the single water injection volume of the water injection module 400 according to the running time of the water pump 600.

[0125] The single water injection volume V1 of the water pump 600 is equal to the single operation time T of the water pump 600 multiplied by the water flow rate Q, that is, V1=Q×T1.

[0126] S220, determining the set number of times according to the single water injection volume and the total capacity of the connecting pipe 700.

[0127] So that after the water pump 600 runs a set number of times, the residual water previously remaining in the connecting pipe 700 can be completely pumped out.

[0128] like Fig.11 As shown, step S220 may include step S221 and step S222.

[0129] S221, determining the minimum number of times the water pump 600 operates according to the single water injection volume and the total capacity of the connecting pipe 700. The minimum number is equal to the total capacity of the connecting pipe 700 divided by the single water injection volume. If the number of times the water pump 600 operates is less than the minimum number, the residual water in the connecting pipe 700 cannot be completely pumped out. If the number of times the water pump 600 operates is greater than the minimum number, the residual water in the connecting pipe 700 can be completely pumped out.

[0130] S222, set any positive integer greater than the minimum number as the set number. For example, if the minimum number is calculated to be 2.1, then the number is set to an integer greater than 3, so that the residual water previously remaining in the connecting pipe 700 is completely pumped out, and the control of the water pump 600 is facilitated.

[0131] With this design, if the cooking appliance 10 has not been used for a long time, the user can issue a cleaning command before the cooking appliance 10 is officially cooked and heated, so that the water pump 600 can run intermittently for a set number of times. Since the set number of times is greater than the minimum number of times, after the water pump 600 has run intermittently for the set number of times, the residual water remaining in the connecting pipe 700 can be completely pumped out, thereby preventing the residual water in the connecting pipe 700 from contaminating the food in the cooking cavity 300 when the cooking appliance 10 is officially cooking.

[0132] The specific set number of times the water pump 600 operates can also be set by the user. The user observes the blockage of the flow channel 412 and adaptively sets the set number of times. Of course, the operating number of the water pump 600 can also be automatically set by the cooking appliance 10 according to the blockage of the flow channel 412. Several possible implementation methods are listed below for illustration:

[0133] Method 1, automatically matching the specified set times according to the running current of the water pump 600. The blockage degree of the flow channel 412 is positively correlated with the working current of the water pump 600. Generally speaking, the more serious the blockage of the flow channel 412 or the water outlet 414 is, the greater the running current of the water pump 600. Therefore, the corresponding running times can be matched according to the running current of the water pump 600. For example, when the running current of the water pump 600 is less than 1A, the water pump 600 is intermittently operated 5 times; when the running current of the water pump 600 is 1-2A, the water pump 600 is intermittently operated 10 times; when the running current of the water pump 600 is 2-4A, the water pump 600 is intermittently operated 20 times; when the running current of the water pump 600 is 6-8A, the water pump 600 is intermittently operated 30 times; when the running current of the water pump 600 is greater than 8A, the water pump 600 is intermittently operated 60 times. It should be understood that the above numerical values ​​are not actual values ​​of real measurements, but are randomly selected to illustrate the control principle of method one.

[0134] Method 2: Automatically match the specified set times according to the water output volume of the water injection module 400 in the same time. The blockage degree of the water injection device and the water output of the water injection module 400 in the same time are negatively correlated. Generally speaking, the more serious the blockage of the flow channel 412 or the water outlet 414, the less water output of the water injection module 400 in the same time. Therefore, the corresponding operation times can be matched according to the water output of the water injection module 400 in the same time. For example, in the same time, if the water output of the water injection module 400 is less than 100ml, the water pump 600 is intermittently operated 100 times; if the water output of the water injection module 400 is 100-200ml, the water pump 600 is intermittently operated 50 times; if the water output of the water injection module 400 is 200-300ml, the water pump 600 is intermittently operated 40 times; if the water output of the water injection module 400 is 300-400ml, the water pump 600 is intermittently operated 30 times; if the water output of the water injection module 400 is greater than 600ml, the water pump 600 is intermittently operated 10 times. It should be understood that the above values ​​are not actual values ​​of real measurements, but are randomly selected to illustrate the control principle of the second method.

[0135] Method three, automatically matching the specified set times according to the flow rate of the water outflow from the water injection module 400 under the same operating current. When the operating current of the water pump 600 is constant, the blockage degree of the water injection device and the flow rate of the water flow are negatively correlated. Generally speaking, the more serious the blockage of the flow channel 412 or the water outlet 414, the smaller the flow rate of the water flow under the same operating current. Therefore, the specified number of operations is matched according to the flow rate of the water outflow from the water injection module 400 under the same operating current. For example, under the same operating current, if the flow rate of the water flow in the water injection module 400 is less than 10ml / s, the water pump 600 is intermittently operated 100 times; if the flow rate of the water flow in the water injection module 400 is 10ml / s-20ml / s, the water pump 600 is intermittently operated 50 times; if the flow rate of the water flow in the water injection module 400 is 20ml / s-30ml / s, the water pump 600 is intermittently operated 40 times; if the flow rate of the water flow in the water injection module 400 is 30ml / s-40ml / s, the water pump 600 is intermittently operated 30 times; if the flow rate of the water flow in the water injection module 400 is greater than 40ml / s, the water pump 600 is intermittently operated 10 times. It should be understood that the above values ​​are not actual values ​​of real measurements, but are randomly selected to illustrate the control principle of mode three.
