[0026] And / or, the cover is further provided with an upper heating element, and the control module is electrically connected to the upper heating element, and the control module is configured to control the upper heating element to stop heating when the detection module detects that the rice soup in the third path is boiling.

[0027] The electric rice cooker is provided with at least one detection module in the corresponding area of the inner container in the annular direction of the height space region formed by the bottom of the inner cavity in the vertical direction from the position of one fourth of the vertical height distance H0 of the inner cavity to the position of two thirds of the vertical height distance H0 of the inner cavity, to detect the liquid level in the inner cavity.

[0028] Compared with the prior art, the electric rice cooker has the following beneficial effects:

[0029] In the present scheme, the inner container is provided in a transparent structure, and the detection module is provided to detect the boiling state of the rice soup in the inner cavity by detecting the light passing through the transparent structure of the inner container and entering and exiting the inner cavity, which can not only detect a large range of the rice soup, but also more accurately detect the boiling height of the rice soup in the inner cavity.

[0030] In the present scheme, the third path formed by the detection module in the inner cavity has a vertical height position and a vertical height distance from the exhaust inlet, which can not only make the rice soup boil to a certain extent to fully cook the rice in the rice soup, but also prevent the rice soup from boiling into the exhaust inlet position during boiling, thereby achieving a better anti-overflow effect.

[0031] In the present scheme, the vertical height distance between the third path and the exhaust inlet is set, which can timely control the working state or working parameter of the lower heating element when the rice soup boils to the third path position, and the rice soup will continue to boil under inertia and then fall back, and the rice soup will not easily boil into the exhaust inlet position under the vertical height distance, thereby achieving a better anti-overflow effect based on the detection information of the detection module.

[0032] In the scheme, the position distribution and structure setting of the first path, the second path and the third path realize that the detection light can effectively form the path through which it passes, and further realize that the detection range area of the detection of the boiling rice soup in the pot cavity is larger. The detection light path structure is beneficial to realize that the detection light is stably received, and further realize that the stability and accuracy of the detection of the detection module on the rice soup are improved.

[0033] In the scheme, the position setting of the emitting part and the receiving part realizes that the receiving part can receive the detection light emitted by the emitting part in the horizontal direction, can more accurately receive the different intensities of the detection light, and further realizes that the detection module more accurately detects the boiling state or boiling height of the rice soup in the pot cavity, and the third path forms a larger detection area range for detecting the rice soup.

[0034] In the scheme, the position distribution setting of the emitting part, the receiving part, the first path, the second path and the third path of the detection module realizes that the detection light can only enter the pot cavity through the transparent structure of the inner container, and can also be received by the receiving part through the transparent structure of the inner container, and cannot be received by reflecting the detection light, so that the detection light can be stably received by the receiving part, and further realizes that the stability and accuracy of the detection of the detection module on the boiling rice soup are improved, and the detection area range for detecting the rice soup in the pot cavity is larger in the horizontal direction, and further improves the accuracy of the detection module for detecting the rice soup.

[0035] In the scheme, the structure setting of the plurality of detection modules realizes that a larger detection range can be effectively formed in the annular direction of the inner container, and a more accurate detection result can be formed. By limiting the cross distribution structure of the plurality of third paths or the length value of the third path, the boiling rice soup can be detected in a larger range in the pot cavity, and the stability and accuracy of the detection of the rice soup are better.

[0036] In the scheme, the structure setting of the first path or the second path in the corresponding area of the transparent structure of the inner container realizes that the detection light is perpendicular to the vertical direction when passing through the area. This effectively reduces the diffusion of the detection light in the vertical direction, realizes that the detection light can be effectively concentrated to pass through the transparent structure of the area, realizes that the rice soup in the pot cavity is accurately and stably detected, and the receiving part can stably and effectively receive the detection light.

[0037] In the scheme, the liquid level in the pot cavity can also be detected based on the transparent structure of the inner container and the detection module, and after detecting the liquid level information, the working state or working parameter of the lower heating element is controlled and adjusted according to the detection information of the detection module, so as to achieve better cooking effect and anti-overflow effect.

[0038] In the scheme, the control module can control and adjust the working state and working parameter of the lower heating element in time based on the detection information of the detection module, that is, the information of the rice soup, such as cooking heating time, heating power, etc., so as to indirectly control the rice soup boiling effect in the pot cavity and the overall cooking time by adjusting the lower heating element in time, thereby realizing the shortening of the cooking time and the improvement of the anti-overflow effect.

[0043] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model will be further described in combination with specific embodiments.

[0044] Embodiment: An electric rice cooker of the utility model, such as Figs. 1 to 3 As shown in the figure, the electric rice cooker can cook rice, and in order to prevent the problem of rice soup overflow during the cooking of rice, especially to prevent the problem of rice soup overflow during the cooking of rice, porridge, etc., the inner container 3 is set as a transparent structure and a detection module 4 is set to detect the boiling state of the rice soup in a large range, so as to control the working state or working parameter of the lower heating element 201 in time during the cooking process, and thus achieve better anti-overflow effect, wherein the structure of the detection module 4 of the scheme realizes a larger detection range of the boiling detection of the rice soup, and the detection result is more accurate, which greatly improves the effect of using the electric rice cooker to cook rice.

[0045] The electric rice cooker of the scheme comprises a cooker body 2, a cooker cover 1 and an inner container 3, the inner container 3 is arranged to be detachably mounted on the cooker body 2, which is convenient for users to install or remove the inner container 3, the inner container 3 is provided with a cooker cavity 301, which is used to contain water and rice for cooking rice, wherein the cooker cover 1 is used to form an opening and closing structure of the cooker cavity 301, mainly the cooker cover 1 is arranged to be rotatable relative to the cooker body 2, the cooker cover 1 forms a closed state on the cooker body 2 or forms an open state relative to the cooker body 2, thereby forming a closing structure or an opening structure of the cooker cavity 301, the inner container 3 is arranged to be a transparent structure, which can form a structure for detecting the passing of light, realizing that the detection light can pass through the transparent structure of the inner container 3 to enter the cooker cavity 301, or the detection light is emitted from the cooker cavity 301 to the outside of the inner container 3 through the transparent structure of the inner container 3, and the upper part of the inner container 3 is provided with a convex edge part 302 which is a convex structure towards the outside of the side part of the inner container 3, the inner container 3 is arranged to be a circular structure in the annular direction, the convex edge part 302 is correspondingly arranged to be an annular ring structure, the convex edge part 302 is convenient for users to carry the inner container 3, or the convex edge part 302 can also form a support structure for placing the inner container 3 on the cooker body 2, wherein the structure for detecting the boiling height of the rice soup in the cooker cavity 301 or the liquid level in the cooker cavity 301 is arranged with a detection module 4 on the region position of the transparent structure region of the inner container 3 on the cooker body 2, and the detection module 4 is arranged at the outside position of the side part of the inner container 3 in the annular direction, mainly the detection module 4 is arranged on the outside region position of the side part of the inner container 3 in the annular direction to form a structure for detecting the rice soup or the liquid level in the cooker cavity 301, the detection module 4 can form a structure for emitting detection light and can form a structure for receiving detection light, specifically, the detection module 4 is arranged to pass through the transparent structure of the inner container 3 to enter the cooker cavity 301, thereby forming a structure for detecting at least the boiling rice soup in the cooker cavity 301, when the detection module 4 emits detection light, the detection light is emitted from the outside of the inner container 3 and enters the cooker cavity 301 through the transparent structure of the inner container 3, at this time the detection light can detect the rice soup or the liquid level in the cooker cavity 301, the liquid level is the water level, when the detection light passes through in the cooker cavity 301 of the inner container 3, a third path 3011 is formed in the cooker cavity 301 for detecting the rice soup when the detection light passes through in the cooker cavity 301, the third path 3011 is the path of the detection light passing through in the cooker cavity 301, the third path 3011 is arranged below the convex edge part 302, thereby forming a certain distance height space region between the detection light and the convex edge part 302 in the vertical direction, which can form a structure for preventing the rice soup from continuously boiling upwards to the outside of the cooker cover 1, even in the state of inertial boiling of the rice soup, it can also form a backfall after boiling a certain height in the height space region, thereby not boiling to the outside of the cooker cover 1, whereinAn exhaust inlet 101 is arranged at the lower end surface of the cover 1, and the exhaust inlet 101 is arranged in communication with the cavity 301 and in communication with the external environment space of the cover 1 to form a structure that allows air in the cavity 301 to flow to the outside of the electric rice cooker. To prevent the rice soup from entering the exhaust inlet 101 when it is boiling, the detection module 4 is arranged to detect the light in the third path 3011 to limit the position of the third path 3011. When the cover 1 is closed, the vertical height distance H1 from the third path 3011 to the exhaust inlet 101 is less than one third of the vertical height distance H0 of the cavity 301. This allows the cavity 301 to have a high height space for fully boiling the rice and rice soup, and the rice soup can effectively boil. When the rice soup boils to the third path 3011, there is still a certain height space above the third path 3011 for the rice soup to boil. The vertical height distance H2 from the third path 3011 to the top surface of the inner container 3 is less than or equal to the vertical height distance H1. This allows the exhaust inlet 101 to be located above the top surface of the inner container 3, so that the rice soup is not easy to enter the exhaust inlet 101 when it is boiling, and the rice soup is not easy to boil out of the cavity 301. This can effectively prevent the rice soup from boiling to the outside of the cover 1.

[0046] The cover 1 is provided with a liner, and the lower end surface of the liner is located above the cavity 301 to directly communicate with the cavity 301. When the liner is closed, the liner is located directly above the cavity 301 to form a structure that blocks steam and temperature. The exhaust inlet 101 is arranged on the liner and penetrates the thickness of the liner from the lower end surface of the liner to the upper surface to form a through hole. The through hole is the exhaust inlet 101, which can be used to discharge steam in the cavity 301 to the outside. If the boiling state of the rice soup in the cavity 301 cannot be well controlled, the rice soup will boil through the exhaust inlet 101 to the outside of the cover 1, which will cause the rice soup to overflow.

[0047] Optionally, the inner container 3 is transparent, which is made of glass or high borosilicate material.

[0048] The specific structure part of the detection module 4 in the scheme is provided with a first path 303 formed on the transparent structure of the inner container 3 when the detection light passes through from the outside of the inner container 3 to the pot cavity 301, the first path 303 forms the passing of the detection light emitted by the detection module 4, mainly forms the detection light emitted from the outside of one side position of the inner container 3 and then passing through the first path 303 to enter the pot cavity 301, and the second path 304 is formed on the transparent structure of the inner container 3 when the detection light passes through from the pot cavity 301 to the outside of the inner container 3, when the detection light passes through the pot cavity 301 from one side position to the other side position of the inner container 3 along the third path 3011, at this time the detection light passes through the transparent structure of the inner container 3 from the inside of the pot cavity 301 to the outside of the inner container 3 along the direction of the third path 3011, and the second path 304 is formed on the transparent structure of the inner container 3, when the detection light in the pot cavity 301 continues to emit along the third path 3011, it will pass through the second path 304 on the transparent structure of the inner container 3 and be emitted to the outside of the other side of the inner container 3 and enter the detection module 4 to be received, thereby forming the emission and reception structure of the detection light, the first path 303 and the second path 304 are arranged in a spaced distribution structure in the annular direction of the inner container 3, and the detection light forms a certain detection area range when passing through the pot cavity 301 by the spaced distribution structure, so that the detection light can cover a certain detection area range in the pot cavity 301 before being emitted to the outside of the inner container 3 through the transparent structure of the inner container 3, thereby forming the structure of the detection path of the detection light. The detection area range of the rice soup is large, and the rice soup can be more accurately detected when the rice soup boils over to determine whether the rice soup boils over to the third path 3011 position.

[0049] The first path 303 and the second path 304 are located below the convex edge portion 302 in the vertical direction, so that the detection light can not pass through the convex edge portion 302, and the detection light can avoid the problem of deviation of the detection accuracy of the detection module 4 caused by the dirt of the convex edge portion 302, and the first path 303 and the second path 304 are located below the convex edge portion 302 to form a certain height distance between the top surface of the inner container 3, which can form a buffer space area for the inertia boiling of the rice soup, thereby effectively preventing the rice soup from overflowing when the rice soup boils over to the exhaust inlet 101 position.

[0050] In order to further improve the accuracy and stability of the detection of the detection module 4, the first path 303 and the second path 304 are arranged in a spaced distribution structure relative to the third path 3011 at different side positions of the third path 3011. The different side positions are mainly arranged at positions not on the same side, such as not simultaneously on the left side of the third path 3011, not simultaneously on the right side of the third path 3011, not simultaneously on the upper side of the third path 3011, not simultaneously on the lower side of the third path 3011, not simultaneously on the front side of the third path 3011, and not simultaneously on the rear side of the third path 3011. Specifically, the first path 303 and the second path 304 can be arranged on the left and right sides of the third path 3011, or the first path 303 and the second path 304 can be arranged on the front and rear sides of the third path 3011, to form a structure in which the first path 303 and the second path 304 are not simultaneously on the same side of the third path 3011. In this way, the detection light forms a third path 3011 with a longer path length after entering the pot cavity 301, so that the length range of the third path 3011 can cover the diameter of the pot cavity 301 in the annular direction, thereby forming a larger detection range for the detection light passing through the third path 3011 to detect the rice soup, and achieving a larger and more accurate detection effect.

[0051] Alternatively, in order to further improve the accuracy and stability of the detection of the detection module 4, the first path 303 and the second path 304 are arranged in a spaced distribution structure relative to the third path 3011 at different side positions of the third path 3011. The different side positions are mainly arranged at positions not on the same side, such as not simultaneously on the left side of the third path 3011, not simultaneously on the right side of the third path 3011, not simultaneously on the upper side of the third path 3011, not simultaneously on the lower side of the third path 3011, not simultaneously on the front side of the third path 3011, and not simultaneously on the rear side of the third path 3011. Specifically, the first path 303 and the second path 304 can be arranged on the left and right sides of the third path 3011, or the first path 303 and the second path 304 can be arranged on the front and rear sides of the third path 3011, to form a structure in which the first path 303 and the second path 304 are not simultaneously on the same side of the third path 3011. In this way, the detection light forms a third path 3011 with a longer path length after entering the pot cavity 301, so that the length range of the third path 3011 can cover the diameter of the pot cavity 301 in the annular direction, thereby forming a larger detection range for the detection light passing through the third path 3011 to detect the rice soup, and achieving a larger and more accurate detection effect.

[0052] Or, the first path 303 and / or the second path 304 are arranged in a structure that extends vertically in the vertical direction and extends in an arc shape in the annular direction of the inner container 3 on the corresponding area of the transparent structure of the inner container 3, so that at least part of the detection light passes through the transparent structure of the inner container 3 in a structure that is perpendicular to the vertical direction on the area of the transparent structure of the inner container 3 for detecting light to pass through; that is, the position of the area of the first path 303 or the second path 304 on the inner container 3 is arranged in a structure that extends in an arc shape in the annular direction of the inner container 3 and in a structure that extends vertically in the vertical direction, so that the detection light enters the pot cavity 301 in a structure that is perpendicular to the vertically extending structure when passing through the area position, so that the detection light passes through the vertically extending structure on the area position perpendicularly, which is beneficial for the detection light to stably pass through the first path 303 on the transparent structure on the inner container 3 to enter the pot cavity 301, or for the detection light to stably pass through the second path 304 on the transparent structure on the inner container 3 to be received by the receiving part 402, thereby improving the detection module 4 to stably and accurately detect whether the boiling rice soup in the pot cavity 301 is located above the third path 3011, and the slight diffusion of the detection light when passing through the arc-shaped extending structure in the annular direction of the area position is also beneficial for the detection light to stably and effectively pass through the first path 303 and enter the pot cavity 301 in a structure of slight diffusion, and also beneficial for the detection light to stably and effectively pass through the second path 304 and be received by the receiving part 402 in a structure of slight diffusion, thereby improving the effect of detecting the rice soup in the third path 3011, and improving the area range of the receiving part 402 to receive the detection light so that the detection area range is larger, thereby preventing the problem of the detection light being unable to be stably received by the receiving part 402 due to excessive diffusion or reflection.

[0053] Or, in order to further improve the accuracy and stability of the detection module 4 to detect the rice soup, the projection area formed by the projection of the exhaust inlet 101 towards the downward direction is at least partially overlapped with the third path 3011, so that at least a part of the third path 3011 is located directly below the exhaust inlet 101. When the detection light passes through the inner cavity 301, at least a part of the detection light is located directly below the exhaust inlet 101. When the inner cavity 301 is filled with the rice soup, the detection light can more stably and effectively detect the rice soup. Because the exhaust inlet 101 is in communication with the inner cavity 301, when the rice soup is stirred upwards, it will be stirred towards the position of the exhaust inlet 101. Because the position of the exhaust inlet 101 is also in communication with the external environment of the pot cover 1, a path for air flow is formed. During the process of the rice soup being stirred towards the position of the exhaust inlet 101, the third path 3011 formed by the detection light is located below the exhaust inlet 101, which can more easily detect the rice soup. Therefore, the detection module 4 can improve the timeliness and accuracy of detecting the rice soup.

[0054] The detection module 4 of the scheme includes a transmitting part 401 for transmitting detection light and a receiving part 402 for receiving detection light. The transmitting part 401 and the receiving part 402 are arranged on the outside of the side of the inner container 3 and are arranged in a spaced distribution structure on different sides of the pot cavity 301. The transmitting part 401 can be located on one side of the pot cavity 301 and outside the inner container 3, and the receiving part 402 can be located on the other side of the pot cavity 301 and outside the inner container 3, forming a spaced distribution structure of the transmitting part 401 and the receiving part 402 in the annular direction of the inner container 3. The structure of the transmitting part 401 and the receiving part 402 is configured such that the first path 303 is located on one side of the transmitting part 401, and the second path 304 is located on one side of the receiving part 402. The first path 303 is mainly located on the transparent structure of the inner container 3 near one side of the transmitting part 401, and the second path 304 is mainly located on the transparent structure of the inner container 3 near one side of the receiving part 402. The detection light passes through the first path 303, the third path 3011 and the second path 304 to form the process of emission and reception, and detects whether the rice soup in the pot cavity 301 is in the state of boiling up and located above the third path 3011 during the emission process. When the detection light is emitted from the side of the inner container 3 near the transmitting part 401 towards the pot cavity 301, it is formed as passing through the first path 303. The first path 303 is a part of the transparent structure of the inner container 3. When the detection light is emitted from the side of the inner container 3 near the receiving part 402 from the inside of the pot cavity 301 towards the receiving part 402, it is formed as passing through the second path 304. The second path 304 is also a part of the transparent structure of the inner container 3. That is, the first path 303 and the second path 304 are both parts of the transparent structure of the inner container 3 for the passage of detection light, but their positions on the transparent structure of the inner container 3 are different, forming a spaced distribution structure in the annular direction of the inner container 3. The structure of the first path 303 and the second path 304 formed by the detection light passing through the pot cavity 301 forms a certain detection area range, so that the detection light can only be emitted to the outside of the inner container 3 through the transparent structure of the inner container 3 after covering a certain detection area range in the pot cavity 301. The structure of the detection light passing through the path formed by the transmitting part 401 and the receiving part 402 not only realizes a large detection area range for the rice soup, but also realizes more accurate detection of the boiling height of the rice soup in the pot cavity 301. The installation and arrangement structure of the detection module 4 is simple and reliable.

[0055] Optionally, the detection module 4 can be an infrared sensor, and the detection light is infrared light.

[0056] In the scheme, the detection module 4 is installed in the corresponding area to detect the rice soup bubble overflowing in the inner pot 301, mainly to detect whether the rice soup bubble will form the third path 3011 in the corresponding area to be submerged or blocked, the emitting part 401 emits detection light to enter the inner pot 301 through the transparent structure of the inner pot 3, and finally a part of the detection light passes through the transparent structure of the inner pot 3 in the forward direction to be received by the receiving part 402, and then according to the intensity of the detection light received by the receiving part 402, it is judged whether there is an overflowing rice soup bubble in the inner pot 301. Specifically, when there is no overflowing rice soup in the inner pot 301 or the overflowing rice soup bubble does not reach the third path 3011 position in the inner pot 301, the detection light passes through the air in the inner pot 301 at this time, and the receiving part 402 receives the detection light emitted by the emitting part 401. The intensity is strong, most of the detection light emitted by the emitting part 401 directly passes through the transparent structure area position of the inner pot 3 close to the emitting part 401, the inner pot 301, the transparent structure area position of the inner pot 3 close to the receiving part 402, and is received by the receiving part 402, and then the receiving part 402 receives the detection light with strong intensity. When the overflowing rice soup bubble in the inner pot 301 reaches the third path 3011 position, the detection light passing through the third path 3011 is blocked by the rice soup bubble at this time, a part of the detection light will be diffused or reflected due to the rice soup bubble. Therefore, only a small part of the detection light passes through the transparent structure of the inner pot 3 and is received by the receiving part 402, and the intensity of the detection light received by the receiving part 402 is weak. Therefore, the detection module 4 can obtain that the rice soup bubble is overflowing to form a detection light on the third path 3011. Block or submerge, that is, the overflowing rice soup bubble has been detected, at this time the cooking parameters of the electric rice cooker can be controlled to realize the rice soup bubble falling back or the rice soup bubble not overflowing to a higher height, that is, better anti-overflow effect can be achieved, and the rice soup is effectively prevented from overflowing to the outer pot 2.

[0057] In order to further improve the stability and accuracy of the receiving part 402 receiving the detection light emitted by the emitting part 401, the emitting part 401 and the receiving part 402 are arranged in a positive relative distribution structure with respect to the pot cavity 301, so that when the detection light emitted by the emitting part 401 passes through the first path 303, the third path 3011 and the second path 304 in turn, the receiving part 402 can positively receive the detection light. At this time, the emitting part 401 and the receiving part 402 are respectively located at both sides of the pot cavity 301 and are arranged in a positive relative distribution structure. In this way, the accuracy of the receiving part 402 receiving the detection light emitted by the emitting part 401 can be improved, and a positive relative receiving detection light structure is formed. The positive relative structure can better receive detection light of different intensities. When the detection module 4 detects the boiling height of the rice soup in the pot cavity 301, the emitting part 401 emits detection light. The detection light passes through the first path 303, the third path 3011 and the second path 304 in turn. In the third path 3011, the detection light passes through the air in the pot cavity 301 or the rice soup in the pot cavity 301. Finally, the detection light is positively incident into the receiving part 402 through the second path 304 and is received by the receiving part 402. The receiving part 402 can better and more accurately receive the detection light, thereby improving the stability and accuracy of the detection module 4 detecting the boiling height of the rice soup.

[0058] Alternatively, in order to further improve the stability and accuracy of the receiving part 402 receiving the detection light emitted by the emitting part 401, at least part of the detection light emitted by the emitting part 401 and the detection light received by the receiving part 402 is arranged in the same horizontal structure, so that at least part of the emitting part 401 and the receiving part 402 is arranged in a positive relative structure. At this time, the emitting part 401 and the receiving part 402 are respectively located at both sides of the pot cavity 301 and are arranged in a distribution structure on the same horizontal plane. In this way, the accuracy of the receiving part 402 receiving the detection light emitted by the emitting part 401 can be improved, and the emitting part 401 and the receiving part 402 are arranged in a positive relative structure on the same horizontal plane. The positive relative structure on the same horizontal plane can better receive detection light of different intensities. When the detection module 4 detects the boiling height of the rice soup in the pot cavity 301, the emitting part 401 emits detection light. The detection light passes through the first path 303, the third path 3011 and the second path 304 in turn. In the third path 3011, the detection light passes through the air in the pot cavity 301 or the rice soup in the pot cavity 301. Finally, the detection light is positively incident into the receiving part 402 along the same horizontal plane through the second path 304 and is received by the receiving part 402. The receiving part 402 can better and more accurately receive the detection light, thereby improving the stability and accuracy of the detection module 4 detecting the boiling height of the rice soup.

[0059] In the scheme, in order to further improve the effect that the rice soup in the pot cavity 301 is not easy to surge to the exhaust inlet 101 position even if there is inertia, the vertical height distance H1 is greater than or equal to 10mm and less than or equal to 30mm, and the size of the vertical height distance H1 is set to realize that under this vertical height distance, not only can the rice soup be in a certain surging state to realize the effect that the rice is fully cooked in the rice soup, but also the rice soup will not surge to the exhaust inlet 101 position during the surging process and the process of continuous surging under inertia, thereby realizing a better anti-overflow effect.

[0060] In the scheme, in order to further improve the effect that the rice soup in the pot cavity 301 is not easy to surge to the exhaust inlet 101 position even if there is inertia, the vertical height distance H1 is greater than or equal to 15mm and less than or equal to 20mm, and the size of the vertical height distance H1 is set to realize that under this vertical height distance, not only can the rice soup be in a certain surging state to realize the effect that the rice is fully cooked in the rice soup, but also the rice soup will not surge to the exhaust inlet 101 position during the surging process and the process of continuous surging under inertia, thereby realizing a better anti-overflow effect.

[0061] In the scheme, in order to realize that the detection module 4 can more accurately detect the rice soup and realize a better anti-overflow effect, the vertical height distance H2 is greater than or equal to 8mm and less than or equal to 15mm, and the setting of the vertical height distance realizes that the detection module 4 can be located below the convex edge part 302 to stably detect the rice soup in the pot cavity 301, and at the same time, the pot cavity 301 has a higher height space distance to cook and surge the rice, which not only can make the rice soup in a certain surging state to realize the effect that the rice is fully cooked in the rice soup, but also can make the rice soup not surge to the exhaust inlet 101 position during the surging process and the process of continuous surging under inertia, thereby realizing a better anti-overflow effect.

[0062] In the present scheme, for the structure part of detecting whether the rice soup in the inner cavity 301 spills into the third path 3011 position in the detection module 4, when the third path 3011 is submerged by the rice soup spilling in the inner cavity 301, the intensity of the detection light received by the receiving part 402 is less than the intensity of the detection light received by the receiving part 402 when the third path 3011 is not submerged by the rice soup spilling in the inner cavity 301, and when the third path 3011 is submerged by the rice soup spilling in the inner cavity 301, the detection light in the inner cavity 301 is configured as a structure that passes through the rice soup, that is, when the detection light does not pass through the rice soup in the inner cavity 301, that is, the spilling height of the rice soup in the inner cavity 301 does not reach the third path 3011 position, the intensity of the detection light that the receiving part 402 can receive at this time is relatively large, and when the detection light passes through the rice soup in the inner cavity 301, that is, the spilling height of the rice soup at this time reaches the position of the third path 3011, the intensity of the detection light that the receiving part 402 can receive at this time is relatively small. Mainly, in the process of the detection light passing through the rice soup, part of the detection light will diffuse or reflect, resulting in that the intensity of the detection light received by the receiving part 402 through the transparent structure of the inner container 3 is small. In this process, the intensity of the detection light will decrease because it passes through the rice soup, and only a small part of the detection light is received by the receiving part 402 in this process. Therefore, the intensity of the detection light received by the receiving part 402 can be used to judge whether there is rice soup at the third path 3011 position in the inner cavity 301, and further judge whether the spilling height of the rice soup in the inner cavity 301 is above the third path 3011 position.

[0063] In order to further increase the detection area range of the detection module 4 in the inner cavity 301 for detecting the rice soup and further improve the stability and accuracy of the detection, in the present scheme, the number of detection modules 4 is set to be multiple, and the multiple detection modules 4 are arranged in a spaced distribution structure in the annular direction of the inner container 3. The multiple detection modules 4 form a larger detection area range in the annular direction of the inner container 3. The detection light emitted by the multiple detection modules 4 passes through the transparent structure of the inner container 3 in different directions in the annular direction of the inner container 3 and enters the inner cavity 301. In this way, the multiple detection lights emitted separately form a larger detection area range, so that when the rice soup spills in the area position outside the center of the inner cavity 301, the detection module 4 can accurately detect whether the rice soup spills to the third path 3011 position, and effectively improve the detection area range of the detection of the rice soup.

[0064] Specifically, at least one part of the two detection modules 4 in the adjacent structure can form a third path 3011 in the inner pot 3, and the third path 3011 is formed in the inner pot 3. The detection light emitted by the two detection modules 4 in the adjacent structure in the annular direction of the inner pot 3 forms a third path 3011 in the inner pot 3. The two third paths 3011 form a cross structure in the inner pot 301, that is, the two detection lights form a cross structure in the inner pot 301. This can realize a larger detection area range in the horizontal direction of the inner pot 301, and the detection light has a larger coverage range in the horizontal direction. It can detect the rice soup in a larger area range in the inner pot 301 to detect whether the rice soup boils over to the third path 3011 position in time, stably and reliably.

[0065] Specifically, at least one part of the two detection modules 4 in the adjacent structure can form a third path 3011 in the inner pot 3, and the third path 3011 is formed in the inner pot 3. The detection light emitted by the two detection modules 4 in the adjacent structure in the annular direction of the inner pot 3 forms a third path 3011 in the inner pot 3. The two third paths 3011 form a cross structure in the inner pot 301, that is, the two detection lights form a cross structure in the inner pot 301. This can realize a larger detection area range in the horizontal direction of the inner pot 301, and the detection light has a larger coverage range in the horizontal direction. It can detect the rice soup in a larger area range in the inner pot 301 to detect whether the rice soup boils over to the third path 3011 position in time, stably and reliably.

[0066] In the scheme, for the heating structure part of the inner container 3, a lower heating element 201 is arranged on the pot body 2, the lower heating element 201 heats the lower region of the inner container 3, the lower heating element 201 is located on the lower side of the inner container 3 and is electrically connected with the control module, the control module is at least used to control the working state or working parameter of the heating element when the detection module 4 detects that there is a boiling rice soup on the third path 3011, when the electric rice cooker starts to work, the detection module 4 detects the rice soup in the pot cavity 301 and feeds back the detection information, the control module adjusts the working state or working parameter of the lower heating element 201 based on the detection information, so as to control the change of the working state or working parameter of the lower heating element 201 to better cook rice based on the boiling state or boiling height of the detected rice soup, wherein the working state can be continuous heating or stopping heating of the lower heating element 201, the working parameter can be increasing or decreasing the heating power of the lower heating element 201, and the overall cooking time of the cooking mode is adjusted based on the detection information of the detection module 4, so as to complete the rice cooking in a more reasonable and shorter time under the boiling state of the rice soup detected by the detection module 4, and better anti-overflow effect can also be achieved to prevent the boiling rice soup from overflowing to the pot cover 1 or outside the pot cover 1.

[0067] And / or, for the heating structure of the pot cavity 301, an upper heating element can also be arranged on the pot cover 1, the upper heating element generates heat when working to heat the pot cavity 301, that is, the heat generated by the upper heating element enters the pot cavity 301 from the upper opening position of the pot cavity 301 to form the effect of heating the space region in the pot cavity 301, the control module is arranged in electrical connection with the upper heating element, and the control module is at least used to make the upper heating element not heat when the detection module 4 detects that there is a boiling rice soup on the third path 3011, that is, when the detection module 4 detects that the rice soup boils to the third path 3011 position, the upper heating element stops heating at this time, so as to prevent the heat generated by the upper heating element from guiding the rice soup to boil upward into the exhaust inlet 101, or even boil to the outside of the pot cover 1, and at the same time, the upper heating element stops heating at this time, which can make the region position below the upper heating element in the pot cavity 301 form a temperature difference to make the rice soup more easily dissipate or break, thereby forming a certain defoaming effect, so as to achieve better anti-overflow effect.

[0068] In the scheme, in order to realize the detection of the liquid level in the pot cavity 301, at least one detection module 4 is arranged on the corresponding area position of the pot body 2 in the annular direction of the inner container 3, which is located at the position of the height space region formed between the position of one fourth of the vertical height distance H0 of the pot cavity 301 from the bottom surface of the pot cavity 301 facing upward to the position of two thirds of the vertical height distance H0 of the pot cavity 301 from the bottom surface of the pot cavity 301 facing upward, so as to detect the liquid level in the pot cavity 301. The detection module 4 is arranged to realize the detection of the liquid level by the detection light. At this time, the detection module 4 is mainly used to detect whether the liquid in the pot cavity 301 is submerged in the third path 3011 and located above the third path 3011. The detection module 4 located below the detection module 4 for detecting the rice soup in the pot cavity 301 is arranged in at least two detection modules 4 in the vertical height direction of the pot cavity 301. The detection module 4 located below is used to detect the liquid level in the pot cavity 301, and the detection module 4 located above is used to detect the height of the rice soup in the pot cavity 301. The detection module 4 is used to realize the detection of the liquid level in the pot cavity 301 by the detection light penetrating through the transparent structure of the inner container 3 and entering and exiting the pot cavity 301. The liquid level in the pot cavity 301 can be more accurately detected, the installation structure of the detection module 4 is simpler, and the cooking parameters of the electric rice cooker can be controlled according to the liquid level information detected by the detection module 4, so as to realize better anti-overflow effect and cooking effect.

[0069] In the structure part of detecting the liquid level in the pot cavity 301 by setting the detection module 4, the detection module 4 for detecting the liquid level forms the first path 303 and the second path 304 on the transparent structure of the inner container 3, and forms the third path 3011 in the pot cavity 301. In the structure part of detecting whether the liquid level is above the position of the third path 3011 by the detection module 4 through the detection light, the intensity of the detection light received by the receiving part 402 when the third path 3011 is submerged by the liquid in the pot cavity 301 is less than the intensity of the detection light received by the receiving part 402 when the third path 3011 is not submerged by the liquid in the pot cavity 301, and the structure in which the intensity of the detection light decreases when the third path 3011 is submerged by the liquid in the pot cavity 301 is formed; that is, the intensity of the detection light that can be received by the receiving part 402 when the detection light does not pass through the liquid in the pot cavity 301 is relatively large, and the intensity of the detection light that can be received by the receiving part 402 when the detection light passes through the liquid in the pot cavity 301 is relatively small. Mainly, part of the detection light is diffused or reflected during the process of the detection light passing through the liquid, resulting in that the intensity of the detection light received by the receiving part 402 through the transparent structure of the inner container 3 is small. In this process, the intensity of the detection light decreases due to passing through the liquid. In this process, only a small part of the detection light is received by the receiving part 402, so that the intensity of the detection light received by the receiving part 402 can be used to judge whether there is liquid at the position of the third path 3011 in the pot cavity 301, and further judge whether the liquid level height in the pot cavity 301 is above the position of the third path 3011.

[0070] It can be understood that the detection light of the detection module 4 in the scheme can not only detect the rice soup, but also detect the liquid level. Different detection modules 4 at different positions on the pot body 2 can be used to detect the liquid level in the pot cavity 301 and the rice soup in the pot cavity 301, respectively. In the scheme, the height of the third path 3011 corresponds to the installation height of the current detection module 4 that forms the third path 3011, so that the heights of the corresponding third paths 3011 of the detection modules 4 at different positions are different. That is, the height of the third path 3011 for detecting the liquid level in the pot cavity 301 is different from the height of the third path 3011 for detecting the rice soup in the pot cavity 301.

[0071] It can be seen that, in the scheme, the working parameters or the working state of the lower heating element 201 can be adjusted in time according to the information of the height of the rice soup bubble detected by the detection module 4, so as to better cook rice based on the detected height of the rice soup bubble, match more appropriate working parameters based on the detected height of the rice soup bubble, and thus achieve better anti-overflow effect, and match more reasonable cooking time based on the detected height of the rice soup bubble, and thus effectively shorten the cooking time of the rice, and the cooking taste of the rice can be improved.

[0072] The working state and the working parameters of the lower heating element 201 are part of the cooking parameters of the electric rice cooker, and the control module controls the adjustment of the cooking parameters according to the detection information of the detection module 4, thereby achieving better anti-overflow effect and cooking effect.

[0073] The parts not mentioned in the scheme can be realized by adopting or referring to the prior art.

[0074] Working principle: The electric rice cooker of the scheme is used to cook rice. During the cooking process of the rice, the detection module 4 is used to detect the rice soup bubble in the pot cavity 301, mainly to detect the rice soup bubble to achieve better anti-overflow effect. At the same time, the detection range of the rice soup bubble is large and the accuracy is high. Specifically, the structure of the detection module 4 is set to realize the emission of the detection light by the emission part 401. The detection light enters the pot cavity 301 through the transparent structure of the inner container 3. The detection light detects whether the rice soup bubble is on the third path 3011 position through which the detection light passes in the pot cavity 301. The receiving part 402 receives the detection light, and judges whether the rice soup bubble is on the third path 3011 position according to the intensity of the received detection light. Then, the working state or the working parameters of the lower heating element 201 are adjusted according to the detection information of the detection module 4, so as to control and adjust the height of the rice soup bubble, finally achieve better anti-overflow effect, and improve the user experience of using the electric rice cooker.

[0075] Those skilled in the art can understand that the above-mentioned embodiments are specific embodiments for implementing the present application, and in actual application, various changes can be made in form and detail without departing from the spirit and scope of the present application, and all are within the protection scope of the present application.
