It should be understood that the specific embodiments described herein are only used for interpreting this application and are not intended to limit this application.

To avoid unnecessary duplication, various possible combination methods of each specific technical feature in this application will not be separately described.

The descriptions of the related orientations "above", "below", "outside", and "inside" are all orientations in the normal use state. The "left" and "right" directions indicate the left and right directions shown in the specific corresponding schematic diagram, and it should be understood that they may or may not be the left and right directions in the normal use state.

[0020] Note that "comprising", "including", or any other variation thereof means covering non-exclusive inclusion. A process, method, article, or device containing a series of elements includes, in addition to those elements, other elements not explicitly listed, or elements inherent to such a process, method, article, or device. When there are no more restrictions, the element limited by the phrase "including one" does not exclude the existence of another same element in the process, method, article, or device containing this element.

[0021] This application provides a lid assembly and a cooking device. The lid assembly can be applied as a pot lid to cooking devices such as rice cookers, steamers, and electric pressure cookers. Note that the application scenario type of this application does not limit the lid assembly structure itself of this application. For the convenience of description, hereinafter, the case where the lid assembly is applied to a rice cooker will be taken as an example to specifically describe the lid assembly.

[0022] In an embodiment of the present application, as shown in FIGS. 1 and 2, the cooking apparatus 1 includes a lid assembly 10 and a main body 20 for cooking. The main body 20 has a cooking chamber 20A with one end open, and the lid assembly 10 can be used to open and close the opening of the cooking chamber 20A. The lid assembly 10 includes an upper lid 11 and a ventilation device 12. Specifically, as shown in FIG. 2, the upper lid 11 may be an integral member for covering the main body of the cooking apparatus 1 to open and close the cooking chamber 20A, or the upper lid 11 may be connected via a plurality of members to form a lid for opening and closing the cooking chamber 20A. For example, the upper lid 11 may include a front lid and a rear lid installed from the outside to the inside. The front lid and the rear lid form a chamber, and the chamber can be used to install various components such as a display panel assembly and a ventilation device. The upper lid 11 may be a part of the above-described lid for opening and closing the cooking chamber 20A. For example, the upper lid 11 may be a front lid. Hereinafter, the upper lid 11 is introduced as the front lid of the lid. It can be understood by those skilled in the art that the specific configuration and form of the upper lid 11 do not affect the limitation on the lid assembly of the present application.

[0023] As shown in FIG. 1, the upper cover 11 has a first mounting region S1 and a second mounting region S2 whose projections on the first plane are separated by a first preset value. The first plane is perpendicular to the thickness direction of the upper cover 11. Specifically, the upper cover 11 may be a substantially thin-walled member having a constant wall thickness, that is, the thickness of the upper cover 11. In a normal use state, the thickness direction of the upper cover 11 as shown in FIG. 2 may be the vertical direction. When the first plane is perpendicular to the thickness direction of the upper cover 11, the direction of the first plane may be substantially the horizontal plane direction. The upper cover 11 has a certain area and can form a projection surface on the first plane. Hereinafter, the surface of the upper cover 11 that can form a projection surface on the first plane is called the surface to be projected. The surface to be projected is divided into a plurality of functional regions according to the size and / or position of the area, so as to effectively distinguish different functional regions. Exemplarily, the surface to be projected of the upper cover 11 may have a first mounting region S1 and a second mounting region S2 that are spaced apart. The separation distance can be flexibly set according to actual needs. The specific separation distance between the two regions can be indicated by the smallest distance between points on these two regions. The area of the first mounting region S1 and the area of the second mounting region S2 may be the same or different. The specific size of the area can be flexibly set according to the actual size of the surface to be projected. The shapes of the first mounting region S1 and the second mounting region S2 can also be flexibly set according to actual needs and are not specifically limited here.

[0024] As shown in FIG. 1, a through hole 11A for discharging steam is formed in the first mounting region S1. Specifically, the upper lid 11 located in the first mounting region S1 can be directly recessed as a through hole 11A communicating with the external environment in the chamber, and the through hole 11A can be used as a steam passage for discharging the steam generated in the main body 20 of the cooking device 1 to the external environment. The specific form of steam discharge can be set flexibly. Optionally, the through hole 11A can directly extend into the cooking chamber 20A through the back lid. In this way, the steam generated in the cooking chamber 20A can be directly discharged to the outside through the through hole 11A. Optionally, a connecting pipe is installed at one end of the through hole 11A close to the cooking chamber 20A, and the connecting pipe can communicate with the cooking chamber 20A. That is, the steam can directly contact the wall surface of the through hole 11A. Optionally, the steam does not have to directly contact the wall surface of the through hole 11A. For example, a steam valve as an independent member can be installed in the through hole 11A, and the steam in the cooking chamber can be discharged through the steam valve.

[0025] As can be understood, when grains such as rice are husked, their surfaces oxidize, generating substances with an old taste. Taking rice as an example, the surface of the husked rice oxidizes to become old rice. During the cooking process, the substances with an old taste in the old rice are released in gaseous form, resulting in the cooked rice having an old taste and a poor texture. As shown in Figure 3, a ventilation device can be installed in the cooking device 1. The ventilation device may be a member having the function of blowing air into the cooking chamber 20A. That is, the ventilation device can continuously suck the air flow in the external environment into the cooking chamber 20A. Under the action of the pressure difference, at least a part of the gas in the cooking chamber 20A can be discharged to the external environment through the steam passage (the arrows in Figure 3 indicate the flow path of the air flow). In this way, originally, at least a part of the gas with an old taste in the cooking chamber 20A can be replaced by the newly incoming fresh air, realizing the exchange of gas in the cooking chamber 20A, that is, ventilation. Thereby, the old taste of the cooked rice is reduced, the effect of removing the old taste is achieved, and the texture of the cooked rice is improved. The ventilation device may also be a member having the function of exhausting air from the cooking chamber 20A. The gas in the cooking chamber 20A can be continuously extracted and discharged to the external environment, and an air intake opening communicating with the external environment can be opened in the cooking device. In this way, the air in the external environment can be replenished and enter the cooking chamber 20A through the air intake opening. In this way, the effect of ventilation can also be achieved.

[0026] As shown in Figure 1, the ventilation device 12 is used to generate an air flow and is connected to the upper lid 11. Specifically, the ventilation device 12 is located in the chamber of the lid assembly 10 and is connected to the upper lid 11. The ventilation device 12 can generate an air flow in the operating state, disturbing the gas in the cooking chamber 20A and realizing ventilation.

[0027] As shown in FIG. 1, the ventilation device 12 is provided in the second mounting area S2. Specifically, when the ventilation device 12 is arranged in the second mounting area S2 and the ventilation device 12 is energized in the operating state, when steam enters the ventilation device 12, the condensed water formed after the steam is cooled may cause a failure of the ventilation device 12 such as a short circuit. The first mounting area S1 and the second mounting area S2 are separated by a first preset value. By separating the two areas and maintaining a certain distance, the steam discharged from the through hole 11A located in the first mounting area S1 is less likely to enter the ventilation device 12 located in the second mounting area S2. Thereby, the stability and service life of the ventilation device 12 in the operating state are effectively improved. In addition, the ventilation device 12 can be provided at any position other than the first mounting area S1 on the projected surface of the upper cover 11. In this way, the flexibility and selectability of the installation position of the ventilation device 12 can be effectively improved.

[0028] The lid assembly of the present application includes an upper lid and a ventilation device. The upper lid has a first mounting area and a second mounting area whose projections on the first plane are separated by a first preset value. A through hole for discharging steam is opened in the first mounting area, and the ventilation device is provided in the second mounting area. By providing the steam discharge area and the ventilation device in different areas, the ventilation device is separated from the steam discharge area. Thereby, the possibility of steam entering the ventilation device is effectively reduced, and further, the stability and service life of the ventilation device in the operating state are effectively improved. Moreover, the ventilation device can be provided at any position other than the steam discharge area, and the flexibility and selectability of the installation position of the ventilation device are effectively improved.

[0029] In some embodiments, the first preset value is 20 mm or more. Specifically, the distance by which the first mounting region S1 and the second mounting region S2 are separated should not be too small. If it is too small, the vapor discharged from the first mounting region S1 is likely to escape to the ventilation device 12 located in the second mounting region S2, and the condensed water formed after the vapor condenses raises the humidity inside the ventilation device 12 too much, affecting its normal operation and service life, and ultimately causing failures such as short circuits. Exemplarily, the distance by which the first mounting region S1 and the second mounting region S2 are separated may be 20 mm or more. By limiting the distance between the two mounting regions, the stability and service life of the ventilation device in its operating state can be further effectively improved. Specifically, the boundary of the first mounting region S1 contains countless points, which can be denoted as the set of points A, and the boundary of the second mounting region S2 also contains countless points, which can be denoted as the set of points B. The distance between the first mounting region S1 and the second mounting region S2 is the minimum value of the length of the line connecting point A and point B. That is, the distances between the boundaries of the first mounting region S1 and the second mounting region S2 are all equal to or greater than the minimum value.

[0030] In some embodiments, as shown in FIG. 1, the upper cover 11 further has a third mounting area S3, and the third mounting area S3 is installed at a distance from both the first mounting area S1 and the second mounting area S2. Specifically, the projection surface of the upper cover 11 can be divided into more regions, each region of the upper cover 11 can be fully utilized, and the diversity of the functions of the cover assembly 10 can be enhanced. Exemplarily, according to actual needs, the projection surface of the upper cover 11 can be divided into three regions installed at intervals, which are the first mounting area S1, the second mounting area S2, and the third mounting area S3 respectively. The third mounting area S3 is used to install the control panel 13, and the user can perform a series of operations such as function selection, switching, on and off in this area. Optionally, the control panel 13 can display the relevant operation parameters of the cooking device, and the operation parameters include the operating time, operating mode, operating state, etc. of the cooking device. The shapes of the three regions may be the same or different, the areas of the three regions may be the same or different, and the relative positions of the three regions are arbitrary. By dividing the projection surface of the upper cover into three regions with different functions, the functional regions of each region can be more clearly divided.

[0031] In some embodiments, the second mounting region S2 and the third mounting region S3 are separated by a second preset value. The meaning of the distance between the second mounting region S2 and the third mounting region S3 is similar to the definition of the distance between the first mounting region S1 and the second mounting region S2, that is, the minimum value of the distance between two points on the boundary between the second mounting region S2 and the third mounting region S3. Specifically, when the ventilation device 12 located in the second mounting region S2 is operating, it forms a flow region of air flow in the second mounting region S2. Since the ventilation device 12 communicates with the cooking chamber 20A, when the cooking device 1 is operating, some of the steam generated in the cooking chamber 20A may enter the air flow passage of the ventilation device 12, so the humidity in the second mounting region S2 increases. Since the control panel 13 installed in the third mounting region S3 is an electrical element, a humid environment may affect the normal operation of the control panel 13. From the perspective of the safety and stability of the use of the control panel 13, the distance between the second mounting region S2 and the third mounting region S3 should not be too small. Exemplarily, the distance between the second mounting region S2 and the third mounting region S3 may be 20 mm or more. Optionally, the second mounting region S2 is located between the first mounting region S1 and the third mounting region S3. Exemplarily, in the case of the flip-type cooking device 1, the lid assembly 10 is rotatably connected to the main body 20 by a hinge assembly. The first mounting region S1 can be installed close to the position of the hinge assembly, and the third mounting region S3 can be installed away from the position of the hinge assembly. In the normal use state, the hinge assembly is located at the rear of the cooking device 1 (the upper position as shown in FIG. 1), and the user is located in front of the cooking device 1 (the lower position as shown in FIG. 1). That is, the first mounting region S1 can be installed close to the rear of the upper lid 11, and the third mounting region S3 can be installed close to the front of the upper lid 11. In this way, the third mounting region S3 is closest to the operation range of the user, making it easy for the user to operate. Also, since the first mounting region S1 is far from the user, the risk of the steam from the first mounting region S1 scalding the user can be effectively reduced. By limiting the distance between the two mounting regions, the stability, safety, and service life of the control panel in the operating state are improved.

[0032] In some embodiments, as shown in FIG. 1, the ventilation device 12 includes an air flow generating device 121 for generating an air flow in an operating state. Specifically, the air flow generating device 121 may be a fan having an air blowing function or a pump body having an air exhausting function, and both can generate an air flow in an operating state. Preferably, the air flow generating device 121 which is a device having an air blowing function is adopted and will be described later. The air flow generating device 121 is directly provided in the chamber in the form of an impeller, and an air supply port is opened in the upper cover 11. The air flow generating device 121 can make the chamber in a negative pressure in an operating state, suck external air into the chamber through the air supply port, and form an air flow (the arrow in FIG. 1 indicates the flow path of the air flow). The air flow generating device 121 may be in the structural form of an impeller and a housing. The housing itself forms an air passage, the impeller is provided in the housing, and the air flow generating device 121 can suck external air directly into the air passage to form an air flow in an operating state. The air flow generating device 121 may be directly communicated with the cooking chamber 20A. As shown in FIG. 1, a guide member 123 is installed. One end of the guide member 123 is communicated with the air flow generating device 121, and the other end of the guide member 123 is communicated with the cooking chamber 20A. So as to ventilate the cooking chamber 20A, the guide member 123 can lead out the air flow generated by the air flow generating device 121 from the upper cover 11. For the blowing form, the guide member 123 leads out the external air flow from the upper cover 11 to the cooking chamber 20A. For the air exhausting form, the air flow in the cooking chamber 20A is led out to the upper cover 11 by the guide member 123 and then led out to the external environment from the upper cover 11. By installing the ventilation device as a specific air flow generating device, the air flow generating device can generate an air flow in an operating state, disturb the gas in the cooking chamber, and realize ventilation.

[0033] In some embodiments, the control panel 13 can control the operation of the air flow generating device 121. Specifically, the control panel 13 is electrically connected to the air flow generating device 121, and the control panel 13 controls the operation or stop of the air flow generating device 121. As can be understood, since the air flow generating device 121 is located inside the chamber, when the cooking device 1 is in an operating state, it is difficult for the user to determine whether the air flow generating device 121 is operating or operating normally, that is, it is difficult for the user to determine whether the cooking device 1 is performing a ventilation operation or a normal ventilation operation. When the user opens the lid assembly 10 in a ventilated state, it will affect the removal effect. Optionally, the control panel 13 is further used to display the operating state of the air flow generating device 121. The operating state of the air flow generating device 121 includes at least one of information such as during operation or non-operation of the ventilation device, and operating parameters. The operating parameters include operating elapsed time, operating speed, operating power, etc. By electrically connecting the control panel and the air flow generating device, the user can control the operation of the air flow generating device by the control panel and directly display the operating state of the air flow generating device by the control panel. The user can easily know the ventilation state of the cooking device, thereby selecting a reasonable timing to open the lid and improving the cooking effect of the cooking device.

[0034] In some other embodiments, the air flow operating state of the air flow generating device may be displayed by other means. As shown in FIG. 1, the ventilation device 12 communicates with the air flow generating device 121 and further includes a visualization assembly 122 for displaying the air flow. Specifically, the visualization assembly 122 may be a mechanical and movable member, and the operating state of the air flow generating device 121 is determined through its movement state.

[0035] Optionally, as shown in FIG. 4, the visualization assembly 122 includes a moving member 1221 and a transparent cover 1222. The moving member 1221 is pushed and moved by the airflow generated by the airflow generating device 121. Specifically, the moving member 1221 is connected to the upper cover 11, which may be a direct connection or an indirect connection. An air passage is also formed in the visualization assembly 122, which communicates with the air passage of the airflow generating device 121. The air passage of the visualization assembly 122 may be an air passage that is completely independent of the upper cover 11 and formed by the visualization assembly 122 itself, or an air passage that is partially formed by the upper cover 11. The moving member 1221 is provided in the air passage of the visualization assembly 122, and the airflow from the airflow generating device 121 can push the moving member 1221 to move within the air passage of the visualization assembly 122. The specific movement form may be rotation, swinging, floating, etc. Exemplarily, the moving member 1221 may be a blade or a turbine rotatably connected to the upper cover 11, and the moving member 1221 is pushed by the airflow and is rotatable relative to the upper cover 11.

[0036] As shown in FIG. 4, the transparent cover 1222 is provided above the moving member 1221 so as to observe the movement of the moving member 1221. Specifically, the user can observe the movement state of the moving member 1221 through the transparent cover 1222. For example, when the user observes through the transparent cover 1222 that the moving member 1221 is moving, it indicates that there is an airflow in the air passage of the visualization assembly 122, that is, the airflow generating device 121 is in an operating state and the cooking device 1 is in a ventilation state. When the user observes through the transparent cover 1222 that the moving member 1221 is not moving, it indicates that the airflow generating device 121 is not operating and the cooking device 1 is not ventilating. When the user observes through the transparent cover 1222 that the moving member 1221 is rotating at a high speed, it indicates that the cooking device 1 is ventilating quickly. When the user observes through the transparent cover 1222 that the moving member 1221 is rotating at a low speed, it indicates that the cooking device 1 is ventilating at a low speed. That is, the user can know the operating state of the cooking device 1 by directly observing the movement state of the moving member 1221 under the transparent cover 1222.

[0037] The visualization assembly is installed as a specific structural form of the moving member and the transparent cover, indirectly displaying the operating state of the air flow generating device in a mechanical movement manner, and further judging the operating state of the cooking device. This installation method has a simple structure and high reliability.

[0038] In some embodiments, the visualization assembly 122 is a part of the structure of the upper cover 11 itself, that is, a part of the visualization assembly 122 is constituted by the upper cover 11. Specifically, as shown in FIG. 4, a first storage chamber 11B for housing the moving member 1221 is formed in the upper cover 11, and the transparent cover 1222 is fixedly connected to the upper cover 11 to seal the opening at one end of the first storage chamber 11B. Specifically, the transparent cover 1222 seals the opening, and the first storage chamber 11B may be the air duct of the visualization assembly 122 and communicates with the air duct of the air flow generating device 121. The air flow from the air duct of the air flow generating device 121 is blown into the first storage chamber 11B, thereby pushing and moving the moving member 1221 provided in the first storage chamber 11B. That is, the upper cover forms a through hole and a first storage chamber with one end open by its own structure. In this way, the components of the cover assembly can be installed with fewer parts, and the structure can be simplified.

[0039] In some other embodiments, the visualization assembly 122 is independent of the structure of the upper cover 11 itself. Specifically, as shown in FIG. 5, the visualization assembly 122 includes a housing 1223, and the housing 1223 forms a second storage chamber 122A for housing the moving member 1221. Specifically, the housing 1223 is surrounded by a second storage chamber 122A having an opening at one end, and the housing 1223 is fixedly connected to the upper cover 11. The fixed connection method may be adhesion, engagement, connection by a fastener, etc., and the upper cover 11 supports and positions the housing 1223. The transparent cover 1222 is connected to the housing 1223 to seal the opening at one end of the second storage chamber 122A. A complete visualization assembly structure can be formed by the housing, the moving member, and the transparent cover. Compared with the integrally formed installation method, this structure is more flexible in installation and is also useful for component replacement.

[0040] Optionally, as shown in FIGS. 4 and 5, the lid assembly 10 further includes a seal spacer 14. Specifically, due to the sealing and isolating effect of the seal spacer 14, the risk that the water vapor discharged from the first mounting area S1 enters the first storage chamber 11B or the second storage chamber 122A can be effectively reduced, and the stability and reliability of the operation of the lid assembly 10 can be improved.

[0041] As described above, this is only a preferred embodiment of the present application and is not intended to limit the protection scope of the present application.
