[0001] The present application relates to the technical field of kitchen utensils, and particularly to a cooking appliance. Background Art
[0002] In related technologies, in order to obtain more nutritious and easier-to-absorb and digest staple foods such as rice, some cooking appliances, such as rice cookers, etc., utilize the relationship between heating and the pressure in the cooking cavity during the cooking process to collect soup such as rice soup into a rice soup collection container.
[0003] There are two ways to set up the rice soup collection container. One is an internal rice soup collection container set inside the cooking appliance, and the other is an external rice soup collection container set outside the cooking appliance. The internal rice soup collection container will occupy the space of the cooking cavity. For the external rice soup collection container, since the soup with a higher concentration is generally close to the bottom of the ingredients, it is difficult for this part of the soup to flow up into the external rice soup collection container.

[0009] In one implementation, the liquid discharge channel includes a pressure control cavity and a first channel and a second channel respectively communicated with the pressure control cavity. The first channel extends along a first direction and is communicated with the cooking cavity, and the second channel extends along a second direction intersecting the first direction and is communicated with the liquid collection port. The pressure control member is movably disposed in the pressure control cavity.
[0010] In one embodiment, the included angle between the first direction and the direction of gravity of the cooking appliance is 0° to 10°.
[0011] In one embodiment, the first channel has an air inlet communicating with the pressure control chamber. When the pressure control member is in the first position, the pressure control member blocks the air inlet so that the liquid discharge channel is in the blocked state; when the pressure control member moves from the first position to the second position, the pressure control member avoids the air inlet so that the liquid discharge channel switches to the conducting state.
[0012] In one embodiment, the ratio of the gravity of the pressure control member to the cross-sectional area of the air inlet is not less than the pressure in the cooking cavity when the pressure control member is in the second position.
[0013] In one embodiment, the main body includes a limiting portion located at the connection between the second channel and the pressure control chamber to limit the movement of the pressure control member in the second direction.
[0014] In one embodiment, the main body has an observation port communicating with the pressure control chamber. The pressure control member is exposed at the observation port. The pressure control and discharge structure includes a light-transmitting window disposed at the observation port.

[0016] In one embodiment, one of the mounting seat and the mounting cover forms a sealing groove, and the other has a sealing portion. The main body further includes a sealing member disposed in the sealing groove. The sealing portion contacts the sealing member by extending into the sealing groove to achieve sealing between the mounting seat and the mounting cover.
[0017] In one embodiment, the cooking appliance further includes a housing.

The inner pot is disposed in the housing, and the pressure control and discharge structure is disposed on the pot lid.
[0018] In one embodiment, the pot lid forms a mounting groove that is recessed in a direction approaching the housing, and the main body is disposed in the mounting groove.
[0019] In one embodiment, the pot lid has an avoidance port communicating with the cooking cavity, and at least part of the structure of the main body passes through the avoidance port so that the liquid discharge channel communicates with the cooking cavity.

The pressure-controlled discharge structure includes a main body having a liquid discharge channel and a pressure control member movably disposed on the main body. The liquid discharge channel communicates with the cooking cavity and the liquid collection port of the liquid collection container. Since the pressure control member can block or conduct the liquid discharge channel through movement, when the pressure control member is in the first position, the pressure control member can increase the pressure in the cooking cavity by blocking the liquid discharge channel. When the pressure in the cooking cavity reaches a certain level, not only can the pressure control member move to the second position to conduct the liquid discharge channel, but also the soup in the cooking cavity, especially the soup near the bottom of the food material, can surge to the liquid discharge channel under the action of pressure and be discharged into the liquid collection container located outside the outer shell through the liquid discharge channel. Therefore, the cooking appliance of the embodiment of the present application has a good soup collection effect. Description of the Drawings

[0031] In the description of the embodiments of the present application, it should be noted that the term "height direction" is based on the Figure 3 described orientation or positional relationship, wherein the "gravity direction" is the downward direction based on the Figure 3 "height direction" in the Figure 5 The terms "first direction" and "second direction" are based on the orientation or positional relationship shown in the Figure 5 These orientation terms are only for convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the embodiments of the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0032] The embodiments of the present application provide a cooking appliance, which may be a cooking appliance such as a rice cooker or an electric pressure cooker. For the convenience of description, the present application takes a rice cooker as an example for description.
[0033] Please refer to Figures 1 to 6 , the cooking appliance includes an inner pot 30, a liquid collection structure 40 and a pressure control and discharge structure 10.
[0034] The liquid collection structure 40 is arranged outside the inner pot 30, and the liquid collection structure 40 includes a liquid collection container 41 having a liquid collection port 41a. The pressure control and discharge structure 10 is used to discharge the soup in the inner pot 30 during the cooking process.
[0035] The inner pot 30 is a container for cooking ingredients such as rice, and the liquid collection structure 40 is used to collect the soup such as rice soup generated during the cooking process. Taking the cooking of rice as an example, during the cooking process, after the rice and water mixture in the inner pot 30 is heated to boiling, the rice soup can flow into the liquid collection container 41 from the liquid collection port 41a through the pressure control and discharge structure 10.
[0036] Please continue to refer to Figures 1 to 3, the liquid collecting structure 40 is arranged outside the inner container 30. That is to say, for a cooking appliance with a housing 20, the liquid collecting structure in the embodiment of the present application can be arranged together with the inner container 30 inside the housing 20 of the cooking appliance, or can be arranged outside the housing 20. Please refer to Figures 1 to 3 , arranging the liquid collecting structure 40 outside the housing 20 can not occupy the internal space of the housing 20 and does not affect the volume of the inner container 30.
[0037] The pressure control and discharge structure 10 includes a main body 11 having a liquid discharge channel 11a and a pressure control member 12 movably arranged on the main body 11. The liquid discharge channel 11a is respectively communicated with the cooking cavity 30a and the liquid collecting port 41a. The pressure control and discharge structure 10 has a blocking state in which the pressure control member 12 blocks the liquid discharge channel 11a and a conducting state in which the pressure control member 12 conducts the liquid discharge channel 11a. The pressure control member 12 moves from the first position to the second position under the action of the pressure in the cooking cavity 30a, so that the pressure control and discharge structure 10 switches from the blocking state to the conducting state.
[0038] The liquid discharge channel 11a is used to discharge the soup from the cooking cavity 30a into the liquid collecting container 41.
[0039] The pressure control member 12 is used to block or conduct the liquid discharge channel 11a. The blocking state means that the pressure control member 12 blocks the liquid discharge channel 11a, and the cooking cavity 30a and the liquid collecting port 41a cannot be communicated through the liquid discharge channel 11a. The conducting state means that the pressure control member 12 conducts the liquid discharge channel 11a, and the cooking cavity 30a and the liquid collecting port 41a are communicated through the liquid discharge channel 11a.
[0040] Specifically, please refer to Figures 3 to 6 , when the pressure control member 12 is in the first position, the pressure control and discharge structure 10 is in the blocking state. When the pressure in the cooking cavity 30a is greater than the gravity of the pressure control member 12, since the cooking cavity 30a and the liquid discharge channel 11a are communicated, the pressure in the cooking cavity 30a can make the pressure control member 12 move from the first position to the second position, so that the pressure control and discharge structure 10 switches from the blocking state to the conducting state. When the pressure in the cooking cavity 30a is less than the gravity of the pressure control member 12, the pressure control member 12 returns from the second position to the first position, so that the pressure control and discharge structure 10 switches from the conducting state to the blocking state.
[0041] Since the pressure control member 12 can block or conduct the liquid discharge channel 11a through movement, when the pressure control member 12 is in the first position, the pressure control member 12 can increase the pressure in the cooking cavity 30a by blocking the liquid discharge channel 11a. When the pressure in the cooking cavity 30a reaches a certain level, it can not only cause the pressure control member 12 to move to the second position to conduct the liquid discharge channel 11a, but also cause the soup in the cooking cavity 30a, especially the soup near the bottom of the food material, to surge into the liquid discharge channel 11a under the action of pressure and be discharged into the liquid collection container 41 located outside the housing 20 through the liquid discharge channel 11a. Therefore, the cooker of the embodiment of the present application has a good soup collection effect.
[0042] In one embodiment, please refer to Figures 4 to 6 , the liquid discharge channel 11a may include a pressure control cavity 11a1 and a first channel 11a2 and a second channel 11a3 respectively communicating with the pressure control cavity 11a1. The first channel 11a2 extends along a first direction and communicates with the cooking cavity 30a, and the second channel 11a3 extends along a second direction intersecting the first direction and communicates with the liquid collection port 41a. The pressure control member 12 is movably disposed in the pressure control cavity 11a1.
[0043] The first channel 11a2 is used to communicate with the cooking cavity 30a, the second channel 11a3 is used to communicate with the liquid collection port 41a, and the pressure control cavity 11a1 is used to accommodate the pressure control member 12. That is, the pressure control member 12 moves between the first position and the second position in the pressure control cavity 11a1, thereby blocking or conducting the liquid discharge channel 11a. Wherein, when the pressure control member 12 is in the second position, the first channel 11a2, the pressure control cavity 11a1 and the second channel 11a3 are communicated, and the soup can surge out of the cooking cavity 30a and flow into the liquid collection container 41 through the first channel 11a2, the pressure control cavity 11a1 and the second channel 11a3 in sequence. By providing the pressure control cavity 11a1, the first channel 11a2 and the second channel 11a3, the soup in the cooking cavity 30a can flow into the liquid collection container 41 more smoothly.
[0044] To facilitate the movement of the pressure control member 12 from the first position to the second position under the action of pressure, exemplarily, the included angle between the first direction and the gravity direction of the cooking appliance can be 0° to 10° (including the end values). That is, the first direction can coincide with the gravity direction, which is equivalent to the first direction being the gravity direction, or the first channel 11a2 extends along the gravity direction. The first direction can also be inclined at a certain angle relative to the gravity direction, but the first channel 11a2 generally extends along the gravity direction.
[0045] Please continue to refer to Figure 5 and Figure 6, the first channel 11a2 has an air inlet 11a21 communicating with the pressure control chamber 11a1. When the pressure control member 12 is in the first position, the pressure control member 12 can block the air inlet 11a21 to make the liquid discharge channel 11a in a blocked state. When the pressure control member 12 moves from the first position to the second position, the pressure control member 12 avoids the air inlet 11a21 to switch the liquid discharge channel 11a to a conducting state.
[0046] The air inlet 11a21 refers to the connection between the first channel 11a2 and the pressure control chamber 11a1. The outer dimension of the pressure control member 12 can be larger than the inner diameter of the air inlet 11a21 so that the pressure control member 12 can not only block the air inlet 11a21 but also stay in the pressure control chamber 11a1.
[0047] To ensure that the pressure control member 12 can be relatively stably in the second position to maintain the discharge of the soup, more preferably, the pressure in the cooking chamber 30a can be controlled above 800 Pa. In addition, the ratio of the gravity of the pressure control member to the cross-sectional area of the air inlet is not less than the pressure in the cooking chamber when the pressure control member is in the second position. Specifically, the mass of the pressure control member 12 is m, the acceleration due to gravity is g, and the cross-sectional area of the air inlet 11a21 is S. The gravity of the pressure control member 12 and the cross-sectional area of the air inlet 11a21 can satisfy the following relationship:
[0048]
[0049] Among them, the gravity of the pressure control member 12 is the product of the mass and the acceleration due to gravity.
[0050] The shape of the pressure control member 12 is not limited. Exemplarily, please refer to Figures 4 to 6 , the pressure control member 12 can be a sphere. In another embodiment, the pressure control member 12 can also be a polyhedron.
[0051] Please refer to Figure 5 and Figure 6 , the main body 11 can also be provided with a limiting portion 111. The limiting portion 111 is located at the connection between the second channel 11a3 and the pressure control chamber 11a1 to limit the movement of the pressure control member 12 in the second direction. That is to say, the limiting portion 111 can prevent the pressure control member 12 from sliding into the second channel 11a3.
[0052] Please continue to refer to Figures 4 to 6 , the main body 11 can also be provided with an observation port 11b communicating with the pressure control chamber 11a1. The pressure control member 12 is exposed at the observation port 11b. The pressure control and discharge structure 10 includes a light-transmitting window 13, and the light-transmitting window 13 is arranged at the observation port 11b.
[0053] The light-transmitting window 13 refers to a window through which light can pass so that the user can observe the pressure control member 12 in the pressure control chamber 11a1.
[0054] The installation positions of the observation port 11b and the light-transmitting window 13 are not limited. Exemplarily, please refer to Figure 2 , Figures 4 to 6 , the observation port 11b and the light-transmitting window 13 can be arranged on the side of the main body 11 facing away from the pot lid 22 to facilitate the user to observe the position state of the pressure control member 12.
[0055] The connection manner between the light-transmitting window 13 and the main body 11 is not limited. Exemplarily, the light-transmitting window 13 is snap-connected to the main body 11.
[0056] By providing the light-transmitting window 13, not only can the user judge the blocking or conduction condition of the liquid discharge channel 11a through the light-transmitting window 13, so as to judge the pressure condition in the cooking cavity 30a, but also the pressure leakage in the cooking cavity 30a can be prevented without affecting the line of sight.
[0057] In one embodiment, please refer to Figure 5 and Figure 6 , the main body 11 may include an installation cover 114 and an installation seat 113 having a first channel 11a2. The installation seat 113 and the installation cover 114 jointly enclose a pressure control cavity 11a1 and a second channel 11a3.
[0058] The connection manner between the installation seat 113 and the installation cover 114 is not limited. Exemplarily, the installation seat 113 and the installation cover 114 may be detachably connected to facilitate the user to disassemble, wash and replace the pressure control member 12.
[0059] Furthermore, one of the installation seat 113 and the installation cover 114 may be formed with a sealing groove 114a, and the other has a sealing portion 1131. The main body 11 further includes a sealing member 112 disposed in the sealing groove 114a. The sealing portion 1131 contacts the sealing member 112 by extending into the sealing groove 114a to achieve the sealing between the installation seat 113 and the installation cover 114.
[0060] Exemplarily, please refer to Figure 5 and Figure 6 , it may be that the installation seat 113 has the sealing portion 1131 and the installation cover 114 has the sealing groove 114a. In another embodiment, it may also be that the installation seat 113 has a seal and the installation cover 114 has a sealing portion.
[0061] By making the sealing portion 1131 extend into the sealing groove 114a to contact the sealing member 112, both the connection stability between the installation seat 113 and the installation cover 114 can be ensured, and the sealing between the installation seat 113 and the installation cover 114 can be ensured, preventing the soup from leaking out from the gap between the installation seat 113 and the installation cover 114.
[0062] In one embodiment, please refer to Figures 1 to 3, the cooking appliance may further include a housing 20, which includes a housing 21 with an opening at the top and a pot lid 22 that is openably and closably covered at the opening. The inner pot 30 is disposed within the housing 21, and the pressure control and discharge structure 10 is disposed on the pot lid 22.
[0063] The pressure control and discharge structure 10 may be disposed outside the pot lid 22 or inside the pot lid 22. Disposing the pressure control and discharge structure on the pot lid 22 can avoid occupying the internal space of the housing 20 and does not affect the volume of the inner pot 30.
[0064] Please refer to Figure 2 , the pot lid 22 may form a mounting groove 22a that is recessed in a direction approaching the housing 21, and the main body 11 is disposed within the mounting groove 22a. This can make the structure of the cooking appliance more compact, and at the same time, the mounting groove 22a can restrict the displacement of the main body 11.
[0065] Please continue to refer to Figure 4 , the pot lid 22 may have an avoidance opening communicating with the cooking cavity 30a, and at least part of the structure of the main body 11 passes through the avoidance opening so that the liquid discharge channel 11a communicates with the cooking cavity 30a.
[0066] At least part of the structure of the main body 11 passing through the avoidance opening can fix the main body 11 on the pot lid 22. For an embodiment where the main body 11 includes a mounting cover 114 and a mounting seat 113 having a first channel 11a2, the part of the mounting seat 113 having the first channel 11a2 may pass through the avoidance opening, so that the first channel 11a2 communicates with the liquid discharge channel 11a.
[0067] Exemplarily, please refer to Figure 4 , the pressure control and discharge structure 10 may further include a discharge pipe 14 having a liquid guide channel 14a. The discharge pipe 14 passes through the avoidance opening, and part of the structure of the discharge pipe 14 extends into the cooking cavity 30a. The liquid discharge channel 11a communicates with the cooking cavity 30a through the liquid guide channel 14a.
[0068] The discharge pipe 14 is used to introduce the soup in the cooking cavity 30a into the liquid discharge channel 11a. Specifically, under the action of high temperature and high pressure, the soup in the cooking cavity 30a surges into the liquid guide channel 14a of the discharge pipe 14. Since the liquid guide channel 14a communicates with the liquid discharge channel 11a, the soup can enter the liquid discharge channel 11a through the liquid guide channel 14a and then be discharged into the liquid collection container 41. Part of the structure of the discharge pipe 14 extending into the cooking cavity 30a can further facilitate the soup in the cooking cavity to enter the liquid guide channel 14a.
[0069] In one embodiment, please refer to Figures 4 to 6, the main body 11 includes a liquid discharge port 11c communicating with the liquid discharge channel 11a, and the part of the main body 11 having the liquid discharge port 11c protrudes from one side of the pot lid 22 so that the liquid discharge port 11c is located above the liquid collection port 41a in the height direction of the cooking appliance.
[0070] The part provided with the liquid discharge port 11c protrudes from one side of the pot lid 22, that is, the liquid discharge port 11c is located on the protruding part. Such a setting can facilitate the alignment of the liquid collection port 41a with the liquid discharge port 11c.
