[0066] At present, most automatic rice cookers on the market adopt an inner pot rice washing method, which adopts a water washing method. During the water washing process, the rice washing water in the inner pot needs to be discharged. If the bottom drainage method is adopted, the waterproof performance of the inner pot is difficult to guarantee. Therefore, a rice washing tube needs to be extended from the upper cover of the cooking utensil into the inner pot to discharge the rice washing water after cleaning. The existing rice washing tube is usually a hard tube, which cannot be extended or retracted, resulting in a high requirement for the installation space of the upper cover of the cooking utensil.

[0067] In order to solve the above problems, the present invention provides a control method of an upper cover assembly 100, an upper cover assembly 100 and a cooking appliance 1000. Figure 1 A partial structural perspective diagram of an embodiment of an upper cover assembly provided by the present invention; Figure 2 for Figure 1 A three-dimensional schematic diagram of the driving member after it moves in the second direction; Figure 3 A partial structural perspective diagram of another embodiment of the upper cover assembly provided by the present invention; Figure 4 for Figure 3 A three-dimensional schematic diagram of the driving member after it moves in the second direction; Figure 5 A partial structural perspective diagram of an embodiment of a cooking utensil provided by the present invention; Figure 6 It is a cross-sectional schematic diagram when the discharge valve is in the initial position in the water washing state; Figure 7 It is a cross-sectional schematic diagram when the discharge valve is in the discharge position in the water washing state; Figure 8 It is a schematic diagram of the structure of a control device for a hardware operating environment involved in an embodiment of the present invention.

[0068] See also Figure 1 to Figure 2 The upper cover assembly 100 includes a cover body 1, a cleaning assembly, a driving mechanism and a control device. The cleaning assembly includes a hose 7 and a pumping device. One end of the hose 7 is fixedly connected to the cover body 1, and the other end of the hose 7 has a storage position for being stored in the cover body 1 and a working position for extending out of the cover body 1; the control device is electrically connected to the pumping device.

[0069] In the solution of the present application, the existing straight tube is replaced by a telescopic tube. In this way, when the rice needs to be washed, the control device can control the other end of the hose 7 to move to the working position. Then, through the control of the control device, after washing is completed, the pumping device is controlled to pump water through the telescopic tube, thereby completing the discharge of rice washing water, so that the rice is washed in the inner cavity of the cooking utensil 1000. When washing is not required, the other end of the hose 7 is stored in the cover body 1, thereby reducing the space requirement for installing the upper cover assembly 100.

[0070] It should be emphasized that the specific form of the telescopic tube is not limited, and the telescopic tube itself can be telescopic and deformable. The user can directly lower one end of the telescopic tube to the bottom of the inner cavity of the cooking utensil 1000. Of course, a driving mechanism can also be provided, and the control device is electrically connected to the driving mechanism, so that the driving mechanism is driven to move under the control of the control device, and one end of the telescopic tube is lowered to the bottom of the inner cavity of the cooking utensil 1000. This is not limited here.

[0071] The telescopic tube can be used to suck and drain the rice washing water in the inner cavity after the cleaning is completed. At the beginning of the cleaning, the cleaning water can also be injected into the inner cavity through the telescopic tube. Of course, the water is fed from the bottom at this time, and the cleaning effect on the rice may not be good. Therefore, the upper cover assembly 100 also includes a water inlet assembly, and the water inlet assembly includes a water inlet provided on the upper cover, so that water flows from the upper cover into the inner cavity, thereby feeding water from the top to enhance the cleaning effect on the rice. During the cleaning process, a blowing device can also be used to blow air into the inner cavity through the telescopic tube, thereby enhancing the cleaning effect on the rice.

[0072] Furthermore, the telescopic tube includes a hose 7, and the upper cover assembly 100 also includes a driving mechanism, including a driving member 4, and the driving member 4 has an active stroke, so that when the driving member 4 is in the active stroke, the other end of the hose 7 is driven to move between the storage position and the working position, and the driving mechanism is electrically connected to the control device. In this way, fully automatic tube placement and collection can be achieved, which reduces user operations and improves user experience.

[0073] The upper cover assembly 100 also includes a feeding bin 2 and a discharge valve 3. The feeding bin 2 is provided with a discharge port 2a. The discharge valve 3 is movably arranged along a first direction and has an initial position and a discharge position. In the initial position, the discharge valve 3 seals the discharge port 2a. In the discharge position, the discharge valve 3 opens the discharge port 2a. The driving mechanism includes a driving member 4, and the driving member 4 is used to directly drive the discharge valve 3 to move from the initial position to the discharge position during its movable stroke.

[0074] In the technical solution provided by the present invention, the feed opening 2a of the feeding bin 2 is controlled to be opened and closed by the feed valve 3, and the way to drive the feed valve 3 to open is to drive the driving member 4 to move, so that the feed valve 3 can be directly driven to move along the first direction, and the driving form structure is simple. When air washing is realized, after the granular food in the feeding bin 2 is removed by the flowing airflow, the feed opening 2a can be opened by driving the driving member 4 to move along the second direction. When water washing is realized, a hose 7 connected to the water supply pipe can be provided on the cover body 1, and the upper end of the hose 7 is fixedly connected to the cover body 1, and the middle part of the hose 7 is located on the side of the driving member 4 in the second direction. When the driving member 4 moves along the second direction, it can not only realize driving the feed valve 3 to move to open the feed opening 2a, but also drive the middle part of the hose 7 to bend toward the second direction, so that the lower end of the hose 7 moves in the first direction to discharge rice washing water, so as to provide an upper cover assembly 100 with a simple driving structure and capable of taking into account both water washing and air washing.

[0075] Specifically, in order to simplify the feeding structure, in this embodiment, the feeding port 2a is provided at the bottom of the feeding bin 2, the feeding valve 3 is movably provided in the up-down direction, and the driving member 4 is movably provided in the transverse direction. In this way, when the cover 1 is provided on the opening of the pot 200, the cover 1 extends in the horizontal direction. In order to facilitate the arrangement of the driving member 4 so that the cover 1 has a smaller volume, the driving member 4 is movably provided in the transverse direction. In this way, the moving direction of the driving member 4 can be consistent with the extending direction of the cover 1, avoiding the need for the cover 1 to be thickened. And when the granular food in the feeding bin 2 needs to enter the pot 200, its gravity can be directly utilized so that the granular food falls directly into the pot 200 through the feeding port 2a, simplifying the components for driving the granular food to the feeding port 2a.

[0076] Specifically, in this embodiment, the driving member 4 has a downward driving surface 411, and the discharge valve 3 has an upward abutting surface 311. At least one of the driving surface 411 and the abutting surface 311 is inclined. In the lateral movement stroke of the driving member 4, the driving surface 411 abuts against the abutting surface 311 to drive the discharge valve 3 to move downward. In this way, the lateral movement stroke is directly converted into a downward movement stroke through the inclined surface guidance by means of the inclined surface abutment, and the driving structure is simple.

[0077] Specifically, in this embodiment, the driving member 4 includes a first protrusion 41, and a downward driving surface 411 is provided at the bottom of the first protrusion 41; the unloading valve 3 includes a second protrusion 31, and an upward abutting surface 311 is provided at the top of the second protrusion 31; the driving surface 411 and the abutting surface 311 are at least inclined, and in the lateral movement of the driving member 4, the driving surface 411 is abutted against the abutting surface 311 to drive the unloading valve 3 to move downward.

[0078] It should be noted that when the first protrusion 41 is located on the left side of the second protrusion 31, the driving member 4 is driven to the right, so that the driving surface 411 and the abutting surface 311 gradually approach each other. When the driving surface 411 is inclined, the driving surface 411 is arranged to extend in a direction inclined upward from left to right. When the abutting surface 311 is inclined, the abutting surface 311 is also arranged to extend in a direction inclined upward from left to right. Of course, the driving surface 411 and the abutting surface 311 can also be arranged to extend in a direction inclined upward from left to right. In this way, when the driving surface 411 and the abutting surface 311 are in contact with each other, the downwardly movable discharge valve 3 is driven to move downward due to the guidance of the inclined surface.

[0079] Of course, it is understandable that when the first convex portion 41 is located on the right side of the second convex portion 31, the driving surface 411 and / or the abutting surface 311 are configured to extend in a direction inclined downward from left to right. This can also ensure that when the driving surface 411 abuts against the abutting surface 311, the unloading valve 3 is driven to move downward.

[0080] It can also be understood that, when the inclination angle of the inclined surface is set smaller, when the driving stroke of the driving member 4 is constant, the downward movable stroke of the discharge valve 3 is also smaller, and vice versa, the downward movable stroke of the discharge valve 3 is larger. The inclination angle of the driving surface 411 and / or the abutting surface 311 can be reasonably set according to the distance of the lateral movable stroke of the driving member 4, the distance that the driving surface 411 and / or the abutting surface 311 can maintain the abutting relationship, and the distance of the downward movable stroke of the discharge valve 3.

[0081] Further, in order to enable the driving member 4 to drive the unloading valve 3 smoothly, and to avoid the first protrusion 41 abutting against the second protrusion 31, when the first protrusion 41 is not located at the geometric center of the driving member 4, the downward force transmitted to the unloading valve 3 by the second protrusion 31 is not vertically downward, so that the driving member 4 and the unloading valve 3 are easily stuck, therefore, in this embodiment, two first protrusions 41 are provided, and the two first protrusions 41 are respectively provided on both sides of the driving member 4 in the horizontal direction; two second protrusions 31 are provided, and the two second protrusions 31 are spaced apart in the longitudinal direction; each first protrusion 41 is provided corresponding to one second protrusion 31. It can be understood that the two first protrusions 41 are arranged in an axisymmetric manner, so that the force acting on the unloading valve 3 can be relatively balanced through two sets of inclined surfaces, so as to avoid the unloading valve 3 from tilting, thereby causing the unloading valve 3 to be stuck between the driving member 4 and the unloading valve 3.

[0082] It should be noted that the lateral movement of the rack can be driven manually or electrically. When driven manually, it can be achieved by directly pushing the rack to move horizontally. Of course, in order to facilitate user use, cooking can be more intelligent.

[0083] For further information, see Figures 1 to 4 In this embodiment, the driving member 4 includes a rack extending in the transverse direction; the driving mechanism also includes a gear 5, which is rotatably mounted on the cover body 1, and the gear 5 is meshed with the rack to drive the rack to move in the transverse direction. In this way, by simply setting a driving motor so that the driving motor is coaxially connected to the gear 5, the rotation of the gear 5 can be converted into the transverse movement of the rack. The rack has a simple structure and low manufacturing cost, and the driving motor and gear 5 that drive the rack to move have a simple structure and occupy a small space on the cover body 1, so that the upper cover assembly 100 does not need to be set too large or too thick, which does not conform to the modern trend of thin and light design.

[0084] Furthermore, in this embodiment, the driving mechanism also includes a driving motor, and the driving motor has an output shaft, and the output shaft is coaxially connected to the gear 5 to drive the gear 5 to rotate synchronously with the output shaft. With such a configuration, a control device can be set. When the user inputs cooking parameters and it is necessary to start driving the rack to move horizontally, the control device controls the rotation of the driving motor, thereby achieving automatic control.

[0085] Furthermore, in order to enable the unloading valve 3 to automatically switch from the unloading position to the initial position, in the present embodiment, the unloading structure further includes an elastic member 6, which is disposed between the unloading valve 3 and the cover body 1, and is used to provide a reset force when the unloading valve 3 switches from the unloading position to the initial position. The elastic member 6 can be configured as a tension spring, and when the first protrusion 41 of the driving member 4 approaches the second protrusion 31, the unloading valve 3 overcomes the tension of the tension spring and moves downward, and the tension spring further deforms to store elastic potential energy, and when the external force driving the driving member 4 to move horizontally disappears, the tension spring restores the deformation, and drives the unloading valve 3 to move upward, so that the unloading valve 3 can automatically switch from the unloading position to the initial position.

[0086] Furthermore, in another embodiment, the middle of the hose 7 is located on one side of the drive member 4 in the lateral direction, and the drive member 4 is used to drive the middle of the hose 7 to bend in the lateral direction during the lateral movement, so that the lower end of the hose 7 moves upward and downward. In this way, the lateral movement of the drive member 4 determines the length of the lateral bending of the hose 7, so that the lower end of the hose 7 can be close to or away from the bottom of the pot.

[0087] It is understandable that when the discharge valve 3 is opened downward, the granular food is controlled to flow from the discharge port 2a into the pot 200. At this time, the lower end of the hose 7 needs to move downward to the bottom of the pot to facilitate the drainage of the rice washing water at the bottom of the pot after washing the rice. When the discharge valve 3 is closed upward, the purpose is to form a closed cooking space in the pot 200. At this time, the lower end of the hose 7 needs to move upward until it is stored on the cover 1.

[0088] Since the movements of the hose 7 and the discharge valve 3 are controlled by the movement direction of the driving member 4, it is necessary to match the positional relationship between the driving member 4, the discharge valve 3 and the hose 7. When the driving surface 411 and / or the abutting surface 311 are arranged to extend in an upwardly inclined direction from left to right, the hose 7 is arranged on the left side of the driving member 4. In this way, when the driving member 4 moves to the right, the driving member 4 abuts against the discharge valve 3 to move downward, and at the same time, the bending length of the hose 7 in the lateral direction is reduced, and the lower end of the hose 7 moves in a direction close to the bottom of the pot. When the driving member 4 moves to the left, the elastic member 6 drives the discharge valve 3 to move upward, and at the same time, the bending length of the hose 7 in the lateral direction is lengthened, and the lower end of the hose 7 moves in a direction away from the bottom of the pot.

[0089] Of course, when the first protrusion 41 is located on the right side of the second protrusion 31, the driving surface 411 and / or the abutting surface 311 are arranged to extend in a direction inclined downward from left to right, and the hose 7 is arranged on the right side of the driving member 4, so that the synchronous coordination of the discharge valve 3 and the hose 7 can also be achieved.

[0090] Furthermore, since the material of the hose 7 is soft, it can avoid interference with other components during bending or straightening. Figures 5 to 7 In this embodiment, the material discharging structure further includes two limiting parts installed on the driving member 4, the two limiting parts are arranged at intervals, and a limiting space is formed between the two limiting parts, and the middle part of the hose 7 is passed through the limiting space. In this way, the two limiting parts are arranged at the position where the hose 7 needs to be limited, so that the hose 7 can move and bend along the set area.

[0091] Specifically, in this embodiment, each of the limiting parts includes a roller 8. In this way, the side wall of the hose 7 abuts against the roller 8, and the roller 8 not only limits the hose 7, but also provides assistance during the movement of the hose 7 to prevent the hose 7 from moving unsmoothly.

[0092] Further, in order to enable the upper cover assembly 100 to better realize the universality of the water washing mode and the air washing mode, please refer to Figure 7 In this embodiment, the discharge valve 3 is penetrated by a through hole 3a in the up and down directions; the hose 7 is penetrated by the through hole 3a, and a blocking portion 91 is provided at the lower end of the hose 7, and the blocking portion 91 is used to block the through hole 3a. It should be noted that, in the water washing mode, the aperture of the through hole 3a is set to be larger than the diameter of the hose 7 to facilitate the up and down movement of the hose 7. However, when the cooking utensil 1000 starts to work, in order to prevent the food or high-temperature steam in the pot 200 from entering the internal space between the discharge valve and the cover body 1 through the through hole 3a, the blocking portion 91 seals and blocks the through hole 3a after the food is washed, so that the pot 200 and the cover body 1 can be enclosed to form a closed cooking cavity.

[0093] In this way, when it is necessary to switch to the air washing mode, it is only necessary to choose to install the unloading valve 3 without the through hole 3a when installing the unloading valve 3. When it is necessary to switch to the water washing mode, it is only necessary to choose to install the unloading valve 3 with the through hole 3a, and then install the hose 7 through the through hole 3a. In this way, by installing different types of unloading valves 3, the driving mechanism can be used universally to realize the normal procedures of unloading and washing granular food materials, so that the upper cover assembly 100 has strong versatility.

[0094] For further information, see Figure 7 In this embodiment, the cleaning assembly further includes a counterweight 92 disposed at the lower end of the hose 7. When the weight of the hose 7 is relatively light, the counterweight 92 facilitates the lower end of the hose 7 to extend into the bottom of the pot.

[0095] It is understandable that the sealing portion 91 and the counterweight block 92 can be separately provided or integrally provided. When the sealing portion 91 and the counterweight block 92 are integrally provided, the through hole 3a can be sealed while allowing the lower end of the hose 7 to extend into the bottom of the pot.

[0096] Furthermore, due to the material of the hose 7 itself, it is easy to generate excessive friction with other adjacent components, and the movement is restricted. In order to make the hose 7 smooth during the movement, a plurality of rollers 8 can be provided. However, when the number of rollers 8 is too large, the internal space is larger. Therefore, please refer to Figures 4 to 7 In this embodiment, the cleaning assembly further includes a sliding spring 10 sleeved on the peripheral side of the hose 7. Since the sliding spring 10 has a smooth surface and has a small friction force with other components, the movement of the hose 7 is prevented from being restricted, and the sliding spring 10 is retractable along the extension direction of the hose 7. Therefore, when the driving member 4 moves horizontally, the sliding spring 10 can be retracted and adapted to the positions of the surrounding components in real time, without affecting the normal operation of the hose 7.

[0097] It is understandable that the hose 7 can also be configured as a partially elastic and retractable structure. When the drive member 4 moves laterally, the hose 7 can adaptively retract and adjust part of the structure according to the morphological characteristics of the surrounding components, thereby not affecting the normal working activities of the hose 7.

[0098] Furthermore, in this embodiment, the discharge valve 3 is detachably mounted on the discharge port 2a, and the cleaning assembly is detachably mounted on the cover body 1. In this way, it is convenient for manufacturers to assemble the discharge valve 3 or the cleaning assembly according to the user's preferences. Of course, when selling the cooking utensil 1000 including the upper cover assembly 100, accessories that are feasible for both air washing and water washing can be distributed. The user selects the required cleaning method to disassemble the unnecessary discharge valve 3 and install the required accessories. At the same time, it is also convenient to replace another type of discharge valve 3 when the discharge valve 3 adapted to one of the cleaning methods fails.

[0099] Furthermore, in order to ensure the sealing of the discharge valve 3 and the discharge port 2a of the feeding bin 2, and to ensure that the airflow generated during the air washing process will not leak out from the gap with the washed impurities, please refer to Figure 5 and Figure 7In the present embodiment, the unloading structure further includes an annular sealing portion 11, which is arranged around the circumference of the unloading valve 3 or on the inner circumference of the unloading port 2a. The material of the annular sealing portion 11 is set as elastic components such as rubber or silicone, so that in the initial position, the annular sealing portion 11 can be deformed appropriately to seal the gap between the unloading valve 3 and the feeding bin 2.

[0100] See also Figure 3 to Figure 4 The upper cover assembly 100 also includes a detection device, which is used to detect the position of the discharge valve 3 and / or the other end of the hose 7. With this arrangement, the position of the discharge valve 3 and / or the other end of the hose 7 can be detected in real time. When a cleaning instruction is received, when the other end of the hose 7 is not in the working position, the driving member 4 is controlled to move to drive the discharge valve 3 to move to the discharge position, thereby ensuring that the hose 7 can extend to the bottom of the inner cavity of the cooking utensil 1000, thereby ensuring the suction and drainage effect of the hose 7 after cleaning.

[0101] During the cooking process, it can be used to detect whether the discharge valve 3 is in the initial position. When it is not in the initial position, the driving member 4 is controlled to move to drive the discharge valve 3 to move to the initial position, thereby preventing steam from entering the feeding bin 2.

[0102] The specific implementation form of the detection device is not limited, and it can be a photoelectric sensor, a reed switch, a micro switch, etc., which is not limited here.

[0103] Specifically, two detection switches are arranged at intervals along the second direction, and the detection switches are provided with a triggering portion and are located on the peripheral side of the driving member 4. The two detection switches include a first detection switch 50 and a second detection switch 51; the driving member 4 is provided with two grooves 52 and a protrusion 53 at intervals along the second direction, wherein, when the driving member 4 drives the other end of the hose 7 to move to the storage position, the triggering portion of the first detection switch 50 is inserted into one of the grooves 52, and when the driving member 4 drives the discharge valve 3 to move to the discharge position, the triggering portion of the first detection switch 50 is inserted into the other groove 52, and when the driving member 4 drives the other end of the hose 7 to move to the storage position, or when the driving member 4 drives the discharge valve 3 to move to the discharge position, the triggering portion of the second detection switch 51 abuts against the protrusion 53.

[0104] It can be understood that, since the unloading valve 3 is closed first and then the other end of the telescopic tube is stored, when the other end of the telescopic tube is in the storage position, the unloading valve 3 is necessarily in the initial position, and the other end of the telescopic tube is first moved to the working position. Therefore, when the unloading valve 3 is in the unloading position, the other end of the telescopic tube is necessarily in the working position.

[0105] The positions of the two grooves 52 can be determined by first installing the first detection switch 50, and when the driving member 4 drives the other end of the hose 7 to move to the storage position, a groove 52 is provided at a position of the driving member 4 corresponding to the touch portion of the first detection switch 50, thereby contacting and pressing the touch portion of the first detection switch 50, so that the state of the first detection switch 50 changes from open to closed. Similarly, the setting of the other groove 52 can be that when the driving member 4 drives the discharge valve 3 to move to the discharge position, a groove 52 is provided at a position of the driving member 4 corresponding to the touch portion of the first detection switch 50, thereby contacting and pressing the touch portion of the first detection switch 50, so that the state of the first detection switch 50 changes from open to closed. With this setting, when the driving member 4 drives the other end of the hose 7 to move to the storage position, or when the driving member 4 drives the discharge valve 3 to move to the discharge position, the first detection switch 5 0 changes from an open state to a closed state. At this time, when the driving member 4 drives the other end of the hose 7 to move to the storage position, and when the driving member 4 drives the discharge valve 3 to move to the discharge position, in one of the two positions, the second detection switch 51 abuts against the protrusion 53, thereby switching from a closed state to an open state, and in the other position, the second detection switch 51 does not abut against the protrusion 53 and remains in a closed state. Therefore, when the state of the first detection switch 50 is switched to a closed state, it can be determined that the driving member 4 drives the other end of the hose 7 to move to the storage position or the driving member 4 drives the discharge valve 3 to move to the discharge position, and then according to whether the state of the second detection switch 51 is closed or open, it is further determined whether the driving member 4 drives the other end of the hose 7 to move to the storage position or the driving member 4 drives the discharge valve 3 to move to the discharge position, thereby detecting the positions of the discharge valve 3 and the telescopic tube.

[0106] See also Figure 8, the control device includes: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0107] The present invention also provides a cooking utensil 1000, which includes a pot 200 and an upper cover assembly 100. The upper cover assembly 100 is arranged to cover the opening of the pot 200. Since the cooking utensil 1000 includes the upper cover assembly 100, the specific structure of the upper cover assembly 100 refers to the above-mentioned embodiment. Since the upper cover assembly 100 of the cooking utensil 1000 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0108] Specifically, in this embodiment, the cooking utensil 1000 includes a fully automatic rice cooker, which includes a material storage component and a liquid storage component. The material storage component is provided with a discharge port, which is connected to the feed port of the feeding bin 2 so that the granular food in the material storage component can enter the feeding bin 2; the liquid storage component is provided with a water outlet, which is connected to the pot 200 so that the water in the liquid storage component can enter the pot 200.

[0109] When installing the discharge valve 3 of the cooking utensil 1000, if the air washing method is selected, the discharge valve 3 without the through hole 3a can be installed, and the discharge valve 3 is installed to the discharge port 2a of the feeding bin 2. The discharge valve 3 seals the discharge port 2a, and the air inlet of the feeding bin 2 is connected with the air supply fan, and the air supply fan forms a flowing airflow in the feeding bin 2. An impurity discharge port connected to the outside is also provided on the feeding bin 2, and a filter is provided at the impurity discharge port to filter and retain the granular food in the feeding bin 2. The flowing airflow enables the impurities to be discharged from the impurity discharge port. After washing the granular food, the driving member 4 drives the discharge valve 3 to move downward, the discharge port 2a is opened, and the granular food falls from the discharge port 2a into the pot 200 to complete the air washing.

[0110] If it is necessary to switch to a water washing method, the discharge valve 3 in the above-mentioned air washing mode can be disassembled and the cleaning component can be installed, that is, the discharge valve 3 with the through hole 3a can be installed at the discharge port 2a, and then the hose 7 is connected to the water supply pipe and the drain pipe, and the hose 7 is passed around the side of the driving member 4 in the lateral direction and then passed downward to the through hole 3a. When it is necessary to clean the granular food, the driving member 4 is driven to move to the right, at which time the discharge valve 3 moves downward, the discharge port 2a is opened, and the granular food falls into the pot 200 from the discharge port 2a. At the same time, the lower end of the hose 7 extends toward the bottom of the pot, and the water supply pipe supplies water, so that the granular food is immersed in water. After cleaning, the water begins to be drained out through the hose 7. After the water is drained, before the subsequent cooking process is required, the driving member 4 is driven to move to the left, at which time the discharge valve 3 moves upward, the discharge port 2a is closed, and at the same time, the driving member 4 drives the hose 7 to bend horizontally for storage. Finally, the sealing portion 91 seals the through hole 3a, so that a closed cooking space is formed in the pot 200.

[0111] Then, the water in the liquid storage component automatically enters the cooker 200 through the water outlet, and then heating and cooking can be started according to the needs of the user.

[0112] To achieve this, please refer to Fig. 9 The present application also proposes a control method for an upper cover assembly 100, wherein the upper cover assembly 100 comprises a cover body 1, a cleaning assembly and a control device; the cleaning assembly comprises a pumping device and a telescopic tube, one end of the telescopic tube is fixedly connected to the cover body 1 and connected to the pumping device, and the other end of the telescopic tube is telescopically arranged to have a storage position for storing in the cover body 1 and a working position for extending out of the cover body 1, and the control device is electrically connected to the pumping device;

[0113] The control method comprises:

[0114] Step S100: at the beginning of cleaning or during cleaning, controlling the other end of the telescopic tube to move to the working position;

[0115] Specifically, controlling the other end of the telescopic tube to move to the working position may be by issuing a prompt message so that the user can move the other end of the telescopic tube to the working position, or by setting a driving mechanism and controlling the movement of the driving mechanism to drive the other end of the telescopic tube to move to the working position, etc., which is not limited here. The movement of the other end of the telescopic tube may rely on the telescopic extension of the telescopic tube itself to move the other end of the telescopic tube, or the telescopic tube itself may be non-retractable and rely on the drive of the driving member 4 to change the length of the portion inside the cover body 1, thereby achieving the purpose of moving the other end of the telescopic tube, which is not limited here.

[0116] It should be noted that since the main purpose of the telescopic tube is to drain water, it needs to extend to the bottom of the inner cavity of the cooking utensil 1000 so as to absorb water from the bottom. Therefore, when a cleaning instruction is received, the other end of the telescopic tube is controlled to move to the working position, and the other end can be moved to the bottom of the inner cavity of the cooking utensil 1000 simply and stably, avoiding interference from rice water.

[0117] At the beginning of the cleaning process, cleaning water can also be injected into the inner cavity through the telescopic tube. Of course, water is introduced from the bottom at this time, and the cleaning effect on the rice may not be good. Therefore, the upper cover assembly 100 also includes a water inlet assembly, and the water inlet assembly includes a water inlet provided on the upper cover, so that water flows from the upper cover into the inner cavity, thereby entering the water at the top to enhance the cleaning effect on the rice. During the cleaning process, an air blowing device can also be used to blow air into the inner cavity through the telescopic tube to enhance the cleaning effect on the rice.

[0118] Step S200: After cleaning is completed, the pumping device is controlled to pump water through the telescopic tube.

[0119] It should be noted that the specific implementation form of the water pumping device is not limited, and it only needs to be able to generate negative pressure in the telescopic tube to perform suction. In this embodiment, the water pumping device is a water pump.

[0120] In the technical solution provided by the present invention, the existing straight tube is replaced by a telescopic tube. In this arrangement, when the rice needs to be washed with water, the control device can control the other end of the hose 7 to move to the working position, so that the rice is washed with water in the inner cavity of the cooking utensil 1000. When washing with water is not required, the other end of the hose 7 is stored in the cover body 1, thereby reducing the space requirement for installing the upper cover assembly 100.

[0121] Further, the telescopic tube includes a hose 7, and the upper cover assembly 100 also includes a driving mechanism, the driving mechanism includes a driving member 4, and the driving member 4 has a movable stroke, so that when the driving member 4 is in the movable stroke, the other end of the hose 7 is driven to move between the storage position and the working position, and the driving mechanism is electrically connected to the control device;

[0122] The step S100 includes:

[0123] Step S110: At the beginning of cleaning or during cleaning, the driving member 4 is controlled to move within the moving stroke to drive the other end of the hose 7 to move to the working position.

[0124] It should be noted that the form in which the driving member 4 drives the other end of the hose 7 to move is not limited. The hose 7 may be rolled up on the driving member 4, so that the other end of the hose 7 can be moved by the rotation of the driving member 4. It may be the form of movement of the driving motor and the rack mentioned above, etc., which is not limited here.

[0125] In the solution of this embodiment, by setting the telescopic tube as a hose 7 and providing a driving mechanism, under the control of the control device, when a cleaning instruction is received, the driving member 4 is controlled to move on the active stroke to drive the other end of the hose 7 to move to the working position, thereby avoiding user operation and realizing the tube retracting and releasing fully automatically.

[0126] At the same time, the upper cover assembly 100 also includes a feeding bin 2 and a discharge valve 3. A discharge port 2a is provided at the bottom of the feeding bin 2. The discharge valve 3 is movably provided along a first direction and has an initial position and a discharge position. In the initial position, the discharge valve 3 seals the discharge port 2a. In the discharge position, the discharge valve 3 opens the discharge port 2a. The driving member 4 is used to drive the discharge valve 3 to move between the initial position and the discharge position during its movable stroke.

[0127] At the beginning of the cleaning step or during the cleaning process, before or at the same time as controlling the other end of the telescopic tube to move to the working position, the control method of the upper cover assembly 100 further includes:

[0128] Step S300: Control the driving member 4 to move to drive the unloading valve 3 to move to the unloading position, so that the food in the storage box enters the cooking cavity.

[0129] In the technical solution provided by the present invention, the discharge port 2a of the feeding bin 2 is controlled to open and close by the discharge valve 3, and the discharge valve 3 is driven to open by driving the driving member 4 to move, so that the discharge valve 3 can be directly driven to move along the first direction, and the driving form structure is simple. When washing with water, a hose 7 connected to a water supply pipe can be provided on the cover body 1, and the upper end of the hose 7 is fixedly connected to the cover body 1, and the middle part of the hose 7 is located on the side of the driving member 4 in the second direction. When the driving member 4 is active, it can not only drive the discharge valve 3 to move to open the discharge port 2a, but also drive the middle part of the hose 7 to bend, so that the lower end of the hose 7 moves in the first direction, and discharge the rice washing water, so as to provide an upper cover assembly 100 with a simple driving structure and capable of taking into account both water washing and air washing.

[0130] It should be noted that the opening of the discharge valve 3 and the extension of the other end of the hose 7 can be performed simultaneously, or the discharge valve 3 can be opened first and then the other end of the hose 7 can be extended, or the other end of the hose 7 can be extended first and then the discharge valve 3 can be opened, and no limitation is made here.

[0131] In one embodiment, since the drainage is performed in the form of suction, it is necessary to ensure that the other end of the hose 7 falls to the bottom of the inner cavity of the cooking utensil 1000 to ensure the drainage effect. Therefore, the control method further includes:

[0132] Step S310: After driving the other end of the hose 7 to move to the working position, the driving member 4 is controlled to move to drive the discharge valve 3 to move to the discharge position.

[0133] In this embodiment, the other end of the hose 7 is first driven to move to the working position, and then the driving member 4 is controlled to move to drive the discharge valve 3 to move to the discharge position. This can effectively prevent the rice from falling first, resulting in the other end of the hose 7 being unable to fall to the bottom of the inner cavity of the cooking utensil 1000. This ensures that the other end of the hose 7 can fall to the bottom of the inner cavity of the cooking utensil 1000, thereby ensuring the drainage effect.

[0134] For details, please refer to Fig.10 The driving of the other end of the hose 7 and the driving of the discharge valve 3 may be performed simultaneously or separately, which is not limited here. The activity stroke of the driving member 4 includes a first activity stroke for driving the hose 7 and a second activity stroke for driving the hose 7 and the discharge valve 3 at the same time. At the beginning or during the cleaning process, the step of controlling the driving member 4 to move on the activity stroke to drive the other end of the hose 7 to move to the working position includes:

[0135] Step S111: at the beginning of cleaning or during cleaning, controlling the driving member 4 to perform a first movable stroke to move the other end of the hose 7 to the working position;

[0136] The step of controlling the driving member 4 to move to drive the unloading valve 3 to move to the unloading position so that the food in the storage box enters the cooking cavity includes:

[0137] Step S311: controlling the driving member 4 to perform a second moving stroke, and driving the unloading valve 3 to move to the unloading position.

[0138] In this embodiment, when the cleaning instruction is received, the driving member 4 is first controlled to perform a first moving stroke. At this time, the other end of the hose 7 can be moved to the working position, that is, to the bottom of the inner cavity of the cooking utensil 1000 without opening the discharge valve 3. Then, the driving member 4 is controlled to perform a second moving stroke to drive the discharge valve 3 to move to the discharge position. At this time, the other end of the hose 7 is at the bottom of the inner cavity. When the driving member 4 continues to move, the position of the other end of the hose 7 will not continue to change. The discharge valve 3 moves to the discharge position, opens the discharge port 2a, and allows the rice in the feeding bin 2 to fall from the discharge port 2a. Then, water is injected into the inner cavity to start the cleaning process of the rice. After the cleaning is completed, the sewage is sucked out through the other end of the hose 7. Finally, the driving member 4 moves in the opposite direction, first closes the feeding bin 2, and then retracts the other end of the hose 7 to complete the entire cleaning process.

[0139] In order to simply and effectively drive the driving member 4 to move, the driving mechanism further includes a driving motor, the driving motor is electrically connected to the control device, the driving member 4 includes a rack extending along the second direction, and the driving motor is connected to the rack via a gear 5;

[0140] The step of controlling the driving member 4 to move to drive the unloading valve 3 to move to the unloading position so that the food in the storage box enters the cooking cavity includes:

[0141] Step S312: first controlling the motor to rotate by a first preset angle to move the other end of the hose 7 to the working position;

[0142] Step S313: Control the motor to rotate to a second preset angle to move the discharge valve 3 to the discharge position.

[0143] In the solution of this embodiment, the driving mechanism also includes a driving motor, and the driving motor has an output shaft, and the output shaft is coaxially connected to the gear 5 to drive the gear 5 to rotate synchronously with the output shaft. In this way, when the user inputs cooking parameters, when it is necessary to start driving the rack to move horizontally, the control device controls the driving motor to rotate, thereby realizing automatic control. By controlling the rotation angle of the motor, the extension or retraction of the hose 7 and the discharge valve 3 can be controlled, and the operation is simple.

[0144] It can be understood that after receiving the cleaning instruction, the motor can be directly controlled to rotate to a third preset angle, which is the sum of the first preset angle and the second preset angle. The motor can be rotated forward and reversely by the third preset angle to simultaneously control the movement of the discharge valve 3 and the other end of the hose 7, directly moving the other end of the hose 7 to the working position and the discharge valve 3 to the discharge position, or simultaneously retracting the discharge valve 3 and the other end of the hose 7. The operation is simple.

[0145] In order to prevent the unloading valve 3 from being in the unloading position during cooking, thereby causing steam to enter the rice unloading bin during cooking, causing water to enter the rice inlet pipe and the rice unloading bin, and causing rice grains to stick together and become moldy, in one embodiment, after the step of controlling the driving member 4 to move to drive the unloading valve 3 to move to the unloading position so that the food in the storage box enters the cooking chamber, the method further includes:

[0146] Step S400: After cleaning is completed, the driving member 4 is controlled to move to drive the discharge valve 3 to return to the initial position.

[0147] In this embodiment, after cleaning is completed, the driving member 4 is controlled to move to drive the discharge valve 3 to return to the initial position, ensuring that the discharge valve 3 is in the initial position during the subsequent cooking process and can seal the feeding bin 2, thereby preventing steam from entering the lower rice bin during cooking, causing water to enter the rice inlet pipe and the lower rice bin, and causing the rice grains to stick together and become moldy.

[0148] In order to prevent the hose 7 from staying in the inner cavity of the cooking utensil 1000 during cooking, thereby affecting the cooking of the rice, or preventing the rice from sticking to the outer surface of the hose 7, thereby making it difficult to clean, in one embodiment, after step S200, the following steps are further included:

[0149] Step S500: After the water is pumped out, the driving member 4 is controlled to move, so as to drive the other end of the hose 7 to move to the storage position.

[0150] In this embodiment, after the water is pumped out, the driving member 4 is controlled to move to drive the other end of the hose 7 to move to the storage position, thereby effectively preventing the hose 7 from staying in the inner cavity of the cooking utensil 1000 and affecting the cooking of rice, or preventing the rice from sticking to the outer surface of the hose 7.

[0151] In order to detect the position of the other end of the hose 7, the upper cover assembly 100 further includes a detection device, which is used to detect the position of the other end of the hose 7. Before the step of controlling the driving member 4 to move on the moving stroke to drive the other end of the hose 7 to move to the working position at the beginning of cleaning or during cleaning, the control method further includes:

[0152] Acquiring detection information of the detection device;

[0153] When a cleaning instruction is received, judging whether the other end of the hose 7 is in the working position according to the detection information;

[0154] When the other end of the hose 7 is not in the working position, the driving member 4 is controlled to move to drive the hose 7 to move to the working position.

[0155] In the scheme of the present implementation, by setting the detection device, the detection device can detect the position of the other end of the hose 7. When a cleaning instruction is received, when the other end of the hose 7 is not in the working position, the driving member 4 is controlled to move to drive the discharge valve 3 to move to the discharge position, thereby ensuring that the hose 7 can extend to the bottom of the inner cavity of the cooking utensil 1000, thereby ensuring the suction and drainage effect of the hose 7 after cleaning.

[0156] Of course, the detection device can also be used to detect the position of the discharge valve 3. During the cooking process, it can be used to detect whether the discharge valve 3 is in the initial position. When it is not in the initial position, the driving member 4 is controlled to move to drive the discharge valve 3 to the initial position, thereby preventing steam from entering the feeding bin 2.

[0157] At the same time, in order to enhance the cleaning effect of the rice, the cleaning component further includes a blowing device, which is used to blow air into the hose 7. After the step of controlling the other end of the telescopic tube to move to the working position when receiving the cleaning instruction, it also includes:

[0158] Step S600: During the cleaning process, the air blowing device is controlled to blow air into the telescopic tube.

[0159] In this embodiment, the blowing device is controlled to blow air into the telescopic tube, so that bubbles can be generated in the water during the process of washing the rice, thereby strengthening the relative movement between the rice and the water and improving the cleaning effect of the rice. In addition, the gas is blown out from the bottom, and the bubbles will move from the bottom to the liquid surface. The movement path is long, and the stirring effect on the rice is good.

[0160] In addition, it should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or system. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or system including the element.
