DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of the specific technical features in the present invention will not be described separately.

[0035] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0036] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device 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 device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. The term "connected" includes both direct and indirect connections unless otherwise specified.

[0037] In a specific embodiment, the steam valve connection structure is used for any cooking device that may generate steam during heating to discharge the steam in the cooking device. The cooking device that the steam valve connection structure can be used for may be, for example, an electric rice cooker, a pressure cooker or an electric kettle. The cooking device that the steam valve connection structure is used for does not have any impact on the structure of the steam valve connection structure. For the sake of convenience, the following description is based on the example of the steam valve connection structure being used for an electric rice cooker.

[0038] In some embodiments, Figure 1 As shown, the steam valve connection structure 10 includes: a mounting member 100 and a steam valve assembly 200. The mounting member 100 is provided with a first connecting member 110. The mounting member 100 may be a component of the electric rice cooker, and is used to install the steam valve assembly 200 on the electric rice cooker. Specifically, the first connecting member 110 is used to be fixedly connected to the steam valve assembly 200, so as to fix the steam valve assembly 200 to the electric rice cooker.

[0039] The steam valve assembly 200 is used to be fixedly installed with the mounting member 100, so as to discharge the steam in the rice cooker out of the rice cooker, thereby reducing the influence of the water vapor on the taste of the rice. The steam valve assembly 200 includes at least two detachably connected parts, that is, the steam valve assembly 200 is composed of multiple parts spliced ​​in a detachable form. When installing the steam valve assembly 200, all parts of the steam valve assembly 200 need to be fixed to the mounting member 100, so that the steam valve assembly 200 can play the function of discharging steam from the rice cooker. Each part of the steam valve assembly 200 is provided with a second connecting member 210 that can be connected to the first connecting member 110, so that each part of the steam valve assembly 200 is fixedly connected to the mounting member 100 through the second connecting member 210. Among them, the first connecting member 110 and the second connecting member 210 are any structures that can be detachably connected. For example, the first connecting member 110 can be a threaded hole, and the second connecting member 210 can be a bolt or stud corresponding to the threaded hole; the first connecting member 110 can also be a buckle, and the second connecting member 210 can be a slot corresponding to the buckle.

[0040] It should be noted that each second connecting member 210 is connected to the first connecting member 110 at the corresponding position to reliably fix the steam valve assembly 200 to the mounting member 100. If only a part of the steam valve assembly 200 is connected to the mounting member 100, the force between the second connecting member 210 arranged in the part and the first connecting member 110 is insufficient to reliably fix the part to the mounting member 100. Only when all the second connecting members 210 arranged in each part of the steam valve assembly 200 are respectively connected to the first connecting member 110, the force between all the second connecting members 210 and the first connecting member 110 can offset the force that separates the steam valve assembly 200 from the mounting member 100, thereby achieving reliable fixation of the steam valve assembly 200 and the mounting member 100, that is, any part of the steam valve assembly 200 that is not installed will result in the steam valve assembly 200 being unable to be reliably fixed to the mounting member 100, thereby achieving the anti-leaking function of each part of the steam valve assembly 200. At the same time, the steam valve connection structure 10 does not need to be equipped with any additional anti-leakage structure, which reduces the manufacturing cost of the steam valve connection structure 10. Figures 2 to 4 , taking the steam valve assembly 200 fixed below the mounting member 100, the force acting to separate the steam valve assembly 200 from the mounting member 100 as the weight of the steam valve assembly 200 itself, and the steam valve assembly 200 including the first part 220A and the second part 230A that are detachably connected as an example, the principle of anti-leakage installation of each part of the steam valve assembly 200 is exemplarily described. It should be understood that according to the different installation positions of the various parts of the steam valve assembly 200 and the different structures of the second connecting members 210, the force on the steam valve assembly 200 can also be in other forms.

[0041] like Figure 2 As shown, the gravity of the first part 220A is the first gravity G1. In the direction perpendicular to the first gravity G1, the distance between the first mass center O1 of the first part 220A and the second connecting member 210 disposed on the first part 220A is the first distance D1. Figure 1 After the first connecting member 110 in the embodiment is connected, the force between the first connecting member 110 and the second connecting member 210 can provide a first force F1 in the opposite direction to the first gravity G1. At the same time, according to the translation theorem of force, the first gravity G1 also applies a first torque M1 to the first connecting member 110 through the second connecting member 210, wherein the first torque M1=G1×D1. After the first connecting member 110 is subjected to the first torque M1, a second torque M2 in the opposite direction to the first torque M1 is applied to the second connecting member 210. The maximum value of the second torque M2 applied by the first connecting member 110 to the second connecting member 210 is greater than the first torque M1, but the maximum value of the first force F1 applied by the first connecting member 110 to the second connecting member 210 is less than the first gravity G1. Figure 1 The first part 220A is connected with the mounting member 100, and the first part 220A is separated from the mounting member 100 under the action of its own gravity.

[0042] like Figure 3 As shown, the gravity of the second part 230A is the second gravity G2. In the direction perpendicular to the second gravity G2, the distance between the second mass center O2 of the second part 230A and the second connecting member 210 disposed on the second part 230A is the second distance D2. Figure 1 After the first connecting member 110 in the embodiment is connected, the force between the first connecting member 110 and the second connecting member 210 can provide a second force F2 in the opposite direction to the second gravity G2. At the same time, according to the translation theorem of force, the second gravity G2 also applies a third torque M3 to the first connecting member 110 through the second connecting member 210, wherein the first torque M3=G2×D2. After the first connecting member 110 is subjected to the third torque M3, a fourth torque M4 in the opposite direction to the second torque M2 in the opposite direction to the third torque M3 is applied to the second connecting member 210. The maximum value of the second force F2 applied by the first connecting member 110 to the second connecting member 210 is greater than the second gravity G2. The maximum value of the fourth torque M4 applied by the first connecting member 110 to the second connecting member 210 is less than the third torque M3. When the second part 230A is connected to the second connecting member 210 alone, the second part 230A is connected to the second connecting member 210 by the first connecting member 110. Figure 1 When connected to the mounting member 100, the second portion 230A will deflect relative to the mounting member 100 under the action of the third torque M3.

[0043] like Figure 4 As shown, after the first part 220A and the second connecting member 230A are connected, and at the same time Figure 1 After the mounting member 100 is connected, the first mass center O1 and the second mass center O2 are located on the same axis parallel to the direction of gravity. The second connecting member 210 disposed on the first part 220A and the second connecting member 210 disposed on the second part 230A are both connected to Figure 1The first connecting member 110 is connected to the second connecting member 210, and the acting forces between the two second connecting members 210 and the two first connecting members 110 are used to offset the acting force that separates the steam valve assembly 200 from the mounting member 100. Specifically, the maximum value of the resultant force of the first acting force F1 and the second acting force F2 is greater than the sum of the first gravity G1 and the second gravity G2, and the maximum value of the resultant force of the second torque M2 and the fourth torque M4 is greater than the sum of the first torque M1 and the second torque M2. The steam valve assembly 200 will neither be separated from the mounting member 100 under the action of gravity, nor will it be deflected relative to the mounting member 100 under the action of the first torque M1 and the second torque M2. The steam valve assembly 200 can be reliably fixed to the mounting member 100, that is, the steam valve assembly 200 can be reliably fixed to the mounting member only when the first part 220A and the second part 230A are not missing.

[0044] An embodiment of the present invention provides a steam valve connection structure, including a mounting member provided with a first connection member and a steam valve assembly including a plurality of detachably connected parts, wherein each part of the steam valve assembly is provided with a second connection member that can be connected to the first connection member. By providing a second connection member in each part of the steam valve assembly, the steam valve assembly can be reliably fixed to the mounting member only when the second connection member of each part is connected to the first connection member, so that when any part of the steam valve assembly is not installed, the steam valve assembly cannot be reliably fixed to the mounting member, thereby realizing the anti-leaking function of the steam valve assembly. At the same time, this steam valve connection structure does not need to additionally provide any anti-leaking structure, thereby reducing the manufacturing cost of the steam valve connection structure. That is, while preventing part of the steam valve assembly from being missed, the manufacturing cost of the steam valve connection structure is reduced.

[0045] In some embodiments, Figure 1 As shown, the number of first connectors 110 is equal to the number of second connectors 210. When no part of the steam valve assembly 200 is missing, all first connectors 110 are connected to the second connectors 210. If there is a first connector 110 that is not connected to the second connector 210, it means that part of the steam valve assembly 200 is missing. That is, by observing whether there is a first connector 110 that is not connected to the second connector 210, it can be more intuitively determined whether the parts of the steam valve assembly 200 are missing, thereby further avoiding the missing of parts of the steam valve assembly 200.

[0046] In some embodiments, Figure 5As shown, the steam valve assembly includes: a steam valve cover 220 and a steam valve seat 230. The steam valve seat 230 is detachably connected to the steam valve cover 220, and both the steam valve cover 220 and the steam valve seat 230 are provided with a second connecting member 210, and both the steam valve cover 220 and the steam valve seat 230 are directly fixedly connected to the mounting member 100. The steam valve cover 220 is used to be arranged between the steam valve seat 230 and the mounting member 100, that is, after the steam valve assembly 200 is fixed to the mounting member 100, the steam valve cover 220 is located between the steam valve seat 230 and the mounting member 100. Optionally, the second connecting member 210 arranged on the steam valve cover 220 and the second connecting member 210 arranged on the steam valve seat 230 are located on opposite sides of the mass center of the steam valve assembly 200.

[0047] It should be noted that, although both the steam valve cover 220 and the steam valve seat 230 are provided with the second connecting piece 210, the force between the second connecting piece 210 provided on the steam valve cover 220 and the first connecting piece 110 is not sufficient to reliably fix the steam valve cover 220 to the mounting piece 100. Similarly, the force between the second connecting piece 210 provided on the steam valve seat 230 and the first connecting piece 110 is not sufficient to reliably fix the steam valve cover 220 to the mounting piece 100. In the state where the second connecting piece 210 provided on the steam valve cover 220 is connected to the first connecting piece 110 and the second connecting piece 210 provided on the steam valve seat 230 is connected to the first connecting piece 110, the steam valve assembly 200 can be reliably fixed to the mounting piece 100, that is, in the state where the steam valve cover 220 and the steam valve seat 230 are not missing, the steam valve assembly 200 can be fixed to the mounting piece 100. Figure 6 Taking the steam valve assembly 200 fixed to the bottom of the mounting member 100 as an example, the principle that the steam valve cover 220 or the steam valve seat 230 cannot be reliably fixed to the mounting member 100 alone, but the steam valve cover 220 and the steam valve seat 230 can be reliably fixed to the mounting member 100 by connecting them and connecting them to the mounting member 100 at the same time is explained by way of example.

[0048] like Figure 6 As shown, the distance between the second connecting member 210 disposed on the steam valve cover 220 and the mass center axis O1 of the steam valve cover 220 is L1, and the distance between the second connecting member 210 disposed on the steam valve seat 230 and the mass center axis O2 of the steam valve seat 230 is L2. Figure 1 The first force F1 between the first connecting member 110 in the steam valve cover 220 is not less than the gravity G1 of the steam valve cover 220 itself. Although the first force F1 along the gravity direction can offset the gravity G1 of the steam valve cover 220 itself, it prevents the steam valve cover 220 from being Figure 1The mounting piece 100 in the steam valve seat 230 may fall off, but according to the force translation theorem, a first torque M1 may be generated to deflect the steam valve cover 220, so that the steam valve cover 220 cannot be reliably fixed to the mounting piece 100; based on similar reasons, a second force F2 provided between the second connecting piece 210 and the first connecting piece 110 of the steam valve seat 230 is not less than the gravity G2 of the steam valve seat 230 itself, but due to the force translation theorem, a second torque M2 may be generated to deflect the steam valve seat 230, so that the steam valve seat 230 cannot be reliably fixed to the mounting piece 100. The steam valve cover 220 and the steam valve seat 230 are connected and connected to the mounting member 10 at the same time. In the direction of gravity, the resultant force of the first force F1 and the second force F2 is greater than the self-force G1 of the steam valve cover 220 and the self-force G2 of the steam valve seat 230, thereby preventing the steam valve cover 220 and the steam valve seat 230 from falling off the mounting member 100. At the same time, since the second connecting member 210 arranged on the steam valve cover 220 and the second connecting member 210 arranged on the steam valve seat 230 are respectively arranged on opposite sides of the mass center of the steam valve assembly 200, the directions of the first torque M1 and the second torque M2 are opposite, and the first torque M1 and the second torque M2 offset each other, thereby reducing the influence of the first torque M1 and the second torque M2 on the steam valve cover 220 and the steam valve seat 230, preventing the steam valve cover 220 and the steam valve seat 230 from deflecting, and thereby enabling the steam valve cover 220 and the steam valve seat 230 to be reliably fixed to the mounting member. Among them, the first torque M1=G1×L1, the second torque M2=G2×L2. Optionally, the second connecting member 210 is set at the position of the steam valve cover 220 and the steam valve seat 230 according to the position of the mass center axis O1 of the steam valve cover 220 and the mass center axis O2 of the steam valve seat 230, as well as the gravity G1 of the steam valve cover 220 and the gravity G2 of the steam valve seat 230, so that the first torque M1 and the second torque M2 are equal in magnitude and opposite in direction, thereby completely offsetting the first torque M1 and the second torque M2, thereby making the steam valve assembly 200 more reliably fixed to the mounting member 100.

[0049] In some embodiments, Figure 6 As shown, the second connector 210 is arranged at the edge of the steam valve cover 220, and the second connector 210 is arranged at the edge of the steam valve seat 230. Different functional structures need to be arranged in the central area of ​​the steam valve seat 230 and the steam valve cover 220 to realize different functions of the steam valve assembly 200. The second connector 210 is arranged at the edges of the steam valve seat 230 and the steam valve cover 220, which can reduce the possibility of interference between the second connector 210 and these functional structures, thereby making the arrangement of the internal structure of the steam valve assembly 200 more flexible.

[0050] In some embodiments, the second connecting member 210 disposed on the steam valve cover 220 and / or the steam valve seat 230 has a plurality of second connecting members 210 disposed at intervals, for example, Figure 8 As shown, in Figure 7 In the case where the weight of the steam valve assembly 200 is heavy, multiple second connectors 210 are arranged at intervals on the steam valve seat 230, which can make the connection between the steam valve assembly 200 and the mounting member 100 more stable. At the same time, the second connectors 210 are arranged at intervals, which can reduce the possibility of interference between the multiple second connectors 210 during the installation process. It should be noted that the structures of the multiple second connectors 210 arranged at intervals are all second connectors 210 of the same structure, and the structures of the corresponding first connectors 110 are also the same structure, thereby reducing the design difficulty and manufacturing difficulty of the mounting member 100 and the steam valve assembly 200.

[0051] In some embodiments, in combination Fig. 9 and Fig.10 The first connector 110 includes a first sub-connector 111 and a second sub-connector 112, the second connector 210 includes a third sub-connector 211 and a fourth sub-connector 212, the third sub-connector 211 is disposed on the steam valve seat 230 and can be connected to the first sub-connector 111, and the fourth sub-connector 212 is disposed on the steam valve cover 220 and can be connected to the second sub-connector 112. The structure of the first sub-connector 111 is different from that of the second sub-connector 112, and the corresponding structure of the third sub-connector 211 is also different from that of the fourth sub-connector 212. By arranging a third sub-connector 211 and a fourth sub-connector 212 with different structures on the steam valve seat 230 and the steam valve cover 220, the posture of the steam valve assembly 200 installed on the mounting member 100 can be controlled, that is, when the steam valve assembly 200 is installed on the mounting member 100 in a preset posture, the third sub-connector 211 can be connected to the first sub-connector 111, and the fourth sub-connector 212 can be connected to the second sub-connector 112.

[0052] In some embodiments, in combination Fig. 9 and Fig.10, the first sub-connector 111 is a slot, the third sub-connector 211 is a connecting plate that can be inserted into the slot, the second sub-connector 112 is a first clamping member, and the fourth sub-connector 212 is a second clamping member that can be clamped with the first clamping member. In the process of installing the steam valve assembly 200, the connecting plate is first inserted into the slot to form a preliminary positioning between the steam valve assembly 200 and the mounting member 100, and the position of the first clamping member (the second sub-connector 112) is directly opposite to the second clamping member (the fourth sub-connector 212), so that the first clamping member can be clamped with the second clamping member. That is, the first sub-connector 111 and the third sub-connector 211 are used to realize the fixed connection between the steam valve assembly 200 and the mounting member 100, and are also used to realize the preliminary positioning between the steam valve assembly 200 and the mounting member 100, so that by inserting the connecting plate into the slot, the position of the first clamping member corresponds to the position of the second clamping member, and then the first clamping member can be clamped with the second clamping member.

[0053] Optional, combined Fig. 9 and Fig.10 , the thickness of the first sub-connector 111 (slot) is greater than the thickness of the third sub-connector 211 (connecting plate), so as to facilitate the preliminary positioning between the steam valve assembly 200 and the mounting member 100. Specifically, in the process of installing the steam valve assembly 200, the connecting plate is first inserted into the slot. At this time, there is a certain acute angle between the bottom surface of the connecting plate and the top surface of the slot. Then the steam valve assembly 200 is rotated around the contact portion between the bottom surface of the connecting plate and the top surface of the slot, so that the second sub-connector 112 (first clamping member) gradually approaches the fourth sub-connector 212 (second clamping member). The steam valve assembly 200 is continuously rotated until the first clamping member is clamped with the second clamping member, and at the same time, the bottom surface of the connecting plate is fitted with the top surface of the slot, so as to achieve the fixation between the steam valve assembly 200 and the mounting member 100. Optionally, the first clamping member is a slot, and the second clamping member is a buckle that can be inserted into the slot.

[0054] In some embodiments, Fig.11 As shown, the steam valve cover 220 is provided with a third clamping member 221, and the steam valve seat 230 is provided with a fourth clamping member 231, and the fourth clamping member 231 can be engaged with the third clamping member 221, so as to fix the steam valve seat 230 with the steam valve cover 220. Optionally, the third clamping member 221 is a buckle 221A, and the fourth clamping member 231 is a slot. Fig.12 The structure of the fastener 221A and the principle that the fastener 221A can be inserted into the slot and realize the connection between the steam valve seat 230 and the steam valve cover 220 are described. Fig.12As shown, the clip 221A includes an elastic arm 222A and a hook 223A, one end of the elastic arm 222A is fixed to the edge of the steam valve cover 220, and the elastic arm 222A protrudes from the edge of the steam valve cover 220, and the free end of the elastic arm 222A opposite to the end fixedly connected to the edge of the steam valve cover 220 is provided with a hook 223A, and the surface of the hook 223A away from the edge of the steam valve cover 220A is provided with an inclined surface 224A, and the surface of the hook 223A close to the edge of the steam valve cover 220A is a plane. In the process of engaging the steam valve seat 230 with the steam valve cover 220, the steam valve seat 230 and the steam valve cover 220 are brought close to each other by applying an external force, so that the clip 221A is engaged with the slot. Specifically, under the action of external force, the wall surface of the steam valve cover 220 contacts the inclined surface 224A of the hook 223A, and the inclined surface 224A decomposes the pressure applied by the wall surface to the inclined surface 224A into a tangential force extending along the direction of the inclined surface 224A and a positive pressure perpendicular to the direction of the inclined surface 224A. Under the action of the positive pressure, the elastic arm 222A undergoes elastic deformation. At the same time, under the action of the tangential force, the wall surface of the steam valve cover 220 continues to move along the inclined surface 224A, so that the steam valve cover 220 and the steam valve seat 230 continue to approach each other until the hook 223A continues to move to the position of the slot. When the hook 223A moves to the position of the slot, the force exerted by the wall surface of the steam valve cover 220 on the hook 223A disappears. At this time, the elastic arm 222A rebounds under the action of its own elastic force to allow the hook 223A to enter the slot. After the buckle 213 enters the slot, the positive pressure between the plane of the hook 223A and the inner wall of the slot prevents the hook 223A from separating from the slot, thereby preventing the steam valve seat 230 and the steam valve cover 220 from separating, that is, the connection between the steam valve seat 230 and the steam valve cover 220 is achieved.

[0055] In some embodiments, Fig.11As shown, the steam valve cover 220 is further provided with a first positioning structure 222, and the steam valve seat 230 is further provided with a second positioning structure 232. The first positioning structure 222 abuts against the second positioning structure 232, so that the third clamping member 221 is engaged with the fourth clamping member 231. Specifically, the first positioning structure 222 is a positioning groove, and the second positioning structure 232 is a positioning dowel protruding from the steam valve seat 230. The positioning dowel can be inserted into the positioning groove, so as to abut against the positioning groove. The relative position of the positioning groove and the fastener 221A is made to correspond to the relative position of the positioning dowel and the slot, so that when the positioning dowel can be inserted into the positioning groove, the fastener 221A can be engaged with the slot. Optionally, the thickness of the first positioning structure 222 (positioning groove) is greater than the thickness of the second positioning structure 232 (inserted bar), so as to facilitate the preliminary positioning of the steam valve seat 230 and the steam valve cover 220. Specifically, during the assembly of the steam valve seat 230 and the steam valve cover 220, the inserted bar is first inserted into the positioning groove, at which time, there is a certain acute angle between the bottom surface of the inserted bar and the top surface of the positioning groove, and then the steam valve seat 230 or the steam valve cover 220 is rotated around the contact portion between the bottom surface of the inserted bar and the top surface of the positioning groove, so that the third clamping member 221 gradually approaches the fourth clamping member 231. The steam valve seat 230 or the steam valve cover 220 is continuously rotated until the third clamping member 221 is clamped with the fourth clamping member 231, and at the same time, the bottom surface of the inserted bar is fitted with the top surface of the positioning groove, so as to achieve the fixation between the steam valve seat 230 and the steam valve cover 220. In some embodiments, the first positioning structure 222 or the second positioning structure 232 is disposed on the second connector 210, that is, the first positioning structure 222 or the second positioning structure 232 is integrated with the second connector 210 into a whole, thereby making the structure of the steam valve assembly 200 more compact. Optionally, the second connector 210 is disposed on the steam valve cover 220, and the first positioning structure 222 is a positioning groove, and the surface of the second connector 210 is concave to form the positioning groove, thereby integrating the second connector 210 with the first positioning structure 222.

[0056] The embodiment of the present invention further provides a cooking device, which is any cooking device that generates steam during the cooking process or needs to heat food by steam. The cooking device can be, for example, an electric rice cooker, a steam-toaster or a pressure cooker. The structure of the cooking device is exemplarily described below by taking the cooking device as an electric rice cooker as an example.

[0057] In some embodiments, Fig.13 As shown, the cooking device includes: an upper cover 20, a cooking body 30 and Figures 1 to 12The steam valve connection structure 10 shown in any one of the drawings. The upper cover 20 includes an inner cover 21 for facing the cooking body 30, and the mounting member 100 of the steam valve connection structure 10 is fixedly connected to the inner cover 21 to fix the steam valve connection structure 10 to the upper cover 20, wherein the steam valve assembly 200 is located on the side of the inner cover 21 facing the cooking body 30, that is, the steam valve assembly 200 is located below the upper cover 20, and when the upper cover 20 is buckled with the cooking body, the steam valve assembly 200 is located between the upper cover 20 and the cooking body 30. Optionally, the mounting member 100 is integrated with the inner cover 21, that is, the mounting member 100 is the inner cover 21 of the upper cover 20, and there is no need to set the inner cover 21 separately, thereby reducing the manufacturing cost of the cooking device 1.

[0058] A hollow accommodating chamber 32 is provided in the cooking body 30, and the accommodating chamber 32 is used to accommodate rice. When the upper cover 20 is buckled with the cooking body 30, the inner cover 21 of the upper cover 20 covers the opening of the accommodating chamber 32, thereby closing the accommodating chamber 32. At the same time, the steam valve assembly 200 is adjacent to the accommodating chamber 32 or is located in the accommodating chamber 32. During the process of cooking rice, the steam valve assembly 200 is used to guide the water vapor generated during the cooking process out of the accommodating chamber 32 to prevent the pressure in the accommodating chamber 32 from being too high, and during the process of keeping the rice warm, prevent the water vapor from condensing into droplets in the accommodating chamber 32 and falling on the rice, causing the cooked rice to soften under the action of the droplets, so that the taste of the cooked rice is better in line with the needs of users. The cooking body 30 is also provided with a third connecting member 31, and the third connecting member 31 can be connected to the upper cover 20 to fix the cooking body to the upper cover 20. Specifically, as Fig.13 As shown, a hinge shaft 33 is provided on one side of the cooking body 30, and the upper cover 20 is rotatably connected to the cooking body 30 through the hinge shaft 33. The upper cover 20 can rotate around the center of the hinge shaft 33 (the rotation direction is as shown in FIG. Fig.13The cooking body 30 is provided with a fourth connection member 120 that can be connected to the third connection member 31 on the other side of the cooking body 30. When the upper cover 20 rotates to a preset position around the center of the hinge shaft 33, the third connection member 31 can be connected to the fourth connection member 120, thereby connecting the upper cover 20 to the cooking body 30. Optionally, the third connection member 31 is a slot, and the fourth connection member 120 is a hook that can be engaged with the slot. When the upper cover 20 rotates to a preset position around the center of the hinge shaft 33, the hook is engaged with the slot, thereby connecting the upper cover 20 to the cooking body 30. Optionally, the first connector 110 is adjacent to the fourth connector 120, and when the first connector 110 is not connected to the second connector 210, there is interference between the first connector 110 and the fourth connector 120, thereby preventing the third connector 31 from connecting to the fourth connector 120, and further making it impossible for the upper cover 20 to be buckled with the cooking body 30; when the first connector 110 is connected to the second connector 210, the first connector 110 moves to a preset position, and at this time, the interference between the first connector 110 and the fourth connector 31 is eliminated, so that the third connector 31 can be connected to the fourth connector 120, and further making it possible for the upper cover 20 to be buckled with the cooking body 30. That is, the cooking device 1 provided in the embodiment of the present invention can also determine whether there is a missing part of the steam valve assembly 200 by whether the upper cover 20 can be buckled with the cooking body 30.
