Description

Technical Field

[0001] The utility model relates to the field of kitchen appliances, in particular to an electric rice cooker. Background Art

[0002] Existing electric rice cookers are mainly used to cook rice. When making porridge or rice gruel, it is difficult for users to strictly follow the required rice-to-water ratio when adding water and rice. This easily leads to the problem of rice soup overflowing. In the prior art, in order to solve the problem of rice soup overflowing, a fan is set to blow air into the cooking cavity in the inner pot, mainly blowing air outside the rice cooker into the cooking cavity, cooling the temperature and dispersing the rice soup by blowing, thereby effectively solving the problem of rice soup overflowing. However, in the solution of blowing air into the cooking cavity, the air flow will directly blow the rice, causing odors or particulate matter in the air to easily adhere to the rice, resulting in the rice easily having odor and unclean problems. In particular, when the user is cooking ingredients such as stir-frying in the environment space where the rice cooker is located, the cooking odor, oil smoke, etc. in the air are easily sucked in by the fan and blown onto the rice, causing the rice to have odor and unclean problems, resulting in a poor user experience.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In this solution, an airflow cavity is set in the pot lid, and airflow is set to blow out and flow in the airflow cavity. The blown airflow can effectively cool down and disperse the rice soup bubbles rising in the pot cavity, thereby preventing the rice soup bubbles from overflowing outside the pot lid, effectively solving the problem of rice soup bubbles overflowing.

[0024] In this solution, the airflow in the airflow cavity can be effectively formed to blow from the edge position toward the middle position in a circular direction and achieve cooling and blowing away the rice soup bubbles rising in the pot cavity in the circular direction, which can prevent the rice soup bubbles at any position in the circular direction from overflowing, thereby enabling the rice cooker to better cook porridge or rice gruel.

[0025] In this solution, the structural arrangement of the airflow cavity, the airflow portion, and the exhaust channel enables the airflow to be effectively formed in the airflow cavity to blow along the inclined direction of the airflow channel, and the airflow will not be blown onto the rice in the pot cavity, thereby effectively preventing odors, particulate matter, etc. in the airflow from entering the rice. While achieving the function of cooling and blowing away the rice soup to achieve an anti-overflow effect, it can also ensure that the rice will not have odors or uncleanness problems caused by the airflow.

[0026] In this solution, the structural arrangement of the air flow port, the lower port and the pot cavity ensures that even if the air flow diffuses when it is blown and flowing in the air flow cavity, the flowing air flow will not diffuse into the pot cavity or onto the rice in the pot cavity. The air flow can be concentrated in the air flow cavity to cool down and disperse the rice soup bubbles rising in the pot cavity, which is equivalent to forming an effect of cold air flow above the pot cavity. In this way, the rice soup bubbles in the pot cavity can be quickly defoamed and dispersed, thereby achieving an effective anti-overflow effect. At the same time, the air flow will not contact the rice while achieving a better anti-overflow effect, so that the rice remains clean and original without any odor.

[0027] The airflow chamber, guide member and other structural arrangements of this scheme can effectively guide the airflow diffused in the airflow chamber and the airflow flowing downward from the lower port position to flow upward, thereby effectively preventing the airflow from blowing onto the rice in the pot cavity, and achieving the airflow in the airflow chamber before guidance and being discharged through the airflow channel, thereby effectively preventing odors, particulate matter, etc. in the airflow from entering the rice.

[0028] In this solution, the guide part, guide cavity and other structural settings can effectively guide the diffused airflow and the downward-flowing airflow to flow upward, effectively preventing the airflow from entering the pot cavity and diffusing onto the rice, thereby effectively preventing odors, particulate matter, etc. in the airflow from entering the rice.

[0029] In this solution, the structural settings of the guide member, the drainage part, the drainage cavity and other structural settings can effectively guide the airflow and ultimately guide the airflow to flow upward through the guide part.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0035] Embodiment: The electric rice cooker of the present utility model is as follows Figures 1 to 2 As shown in the structure, the rice cooker is mainly used to cook rice, especially porridge or congee. During the process of cooking porridge or congee, the present invention can effectively solve the problem of rice soup bubbles overflowing. At the same time, in the process of using air flow to cool down and blow away the rice soup bubbles, the air flow will not contact the rice, which can effectively prevent the odor or particulate matter in the air flow from entering the rice, causing the rice to have odor and uncleanness, thereby greatly improving the user experience.

[0036] The electric rice cooker of this scheme comprises a pot body 1 and a pot cover 2, the pot body 1 is provided with a pot cavity 3, the pot cavity 3 is detachably mounted on the pot body 1, the pot cavity 3 is provided with a pot cavity 301, the pot cavity 301 is used to hold rice and water for cooking, the pot cover 2 is arranged to be able to rotate relative to the pot body 1 to form a structure for opening and closing the pot cavity 301, when the electric rice cooker is started to cook, the pot cover 2 is formed to form a closed structure for the pot cavity 301, at this time the pot cover 2 is located directly above the pot cavity 301; wherein, in order to achieve the anti-overflow effect of the rice soup bubbles in the pot cavity 301, to prevent the rice soup bubbles from rising too high and overflowing to the outside of the pot cover 2, The problem occurs. In this solution, an airflow chamber 201 with an annular structure is provided on the pot cover 2. The airflow chamber 201 is arranged to be located above the pot cavity 301 and is connected with the pot cavity 301 in the vertical direction. The airflow chamber 201 has an annular structure for the flow of air to form a blowing effect. The airflow chamber 201 is connected with the pot cavity 301 in the vertical direction to achieve the effect of airflow blowing above the pot cavity 301, thereby achieving cooling of the upper part of the pot cavity 301, forming temperature convection to make the rice soup bubbles rising upward in the pot cavity 301 be cooled, blown away and defoamed, thereby achieving a better anti-overflow effect.

[0037] Among them, an exhaust channel 202 is also provided on the pot lid 2, and the lower port 2021 of the exhaust channel 202 is in a communication structure with the airflow cavity 201, and the upper port 2022 of the exhaust channel 202 is in a communication structure with the outside of the pot body 1, so that the airflow in the airflow cavity 201 can be moved to the position of the lower port 2021 after blowing, so that the airflow can finally move to the upper port 2022 for discharge, thereby forming a path effect of airflow entry, movement, and discharge. The lower port 2021 is mainly set to be located in the middle position or center position of the airflow cavity 201 in the annular structure, so that the airflow on the annular structure can be blown from the outer edge position toward the middle position or center position and then discharged, thereby forming a larger airflow flow path, which can achieve a better anti-overflow effect.

[0038] The specific structure is as follows: an airflow portion 203 is provided at the edge of the airflow cavity 201, and an airflow channel 2031 is provided in the airflow portion 203. The airflow channel 2031 is used for the airflow to flow through and enter the airflow cavity 201. The airflow channel 2031 is set to be located below the lower port 2021 and above the pot cavity 301, so that the airflow forms a blowing flow effect from bottom to top above the pot cavity 301, and the airflow channel 2031 is set to be inclined upward toward the position of the lower port 2021, so that the airflow is blown out through the airflow port 2032 at the end position of the airflow channel 2031 and then forms a structure that flows to the position of the lower port 2021 along an inclined direction above the pot cavity 301. The inclined structure enables the airflow to flow from bottom to obliquely upward along the inclined direction, so that even if there is diffusion in the process of the airflow, The diffused airflow will not enter the pot cavity 301 to contact the rice. The airflow flows in an inclined direction to achieve an anti-overflow effect and is finally discharged from the lower port 2021. At the same time, a guide member 204 is also provided on the pot cover 2. At least a part of the guide member 204 is located in the airflow cavity 201 and extends toward the pot cavity 301. A guide portion 2041 is provided on the guide member 204 to form a structure for guiding the airflow to flow upward so that the airflow will not enter the pot cavity 301. The airflow diffused in the airflow cavity 201 and the airflow flowing downward from the lower port 2021 can be effectively guided to flow upward, thereby effectively preventing the airflow from blowing onto the rice in the pot cavity 301, and realizing that the airflow flows in the airflow cavity 201 before being guided and discharged through the airflow channel 2031, thereby effectively preventing odors, particulate matter, etc. in the airflow from entering the rice.

[0039] Among them, an air flow device can be set in the pot cover 2. The air flow device is mainly a fan. The fan is started to generate air flow, which mainly sucks the air flow outside the rice cooker and blows it onto the air flow part 203, and passes through the air flow channel 2031, and then blows it out through the air flow port 2032 on the air flow channel 2031, so that the air flow is blown into the air flow cavity 201. At this time, the air flow can prevent the rice soup bubbles rising in the pot cavity 301 from overflowing.

[0040] In this solution, in order to further improve the effect of preventing the airflow from entering the pot cavity 301 and contacting the rice, the vertical height formed by the lower port 2021 and the airflow port 2032 in the vertical direction is set to H1, and the vertical height formed by the airflow port 2032 and the top surface of the pot 3 in the vertical direction is set to H2, and H2 is set to be greater than H1, so that when the airflow flows and diffuses in the inclined direction, the diffusion position of the airflow is located above the pot cavity 301, thereby forming a structure in which the airflow does not enter the pot cavity 301 and contact the rice, so that there is a relatively larger vertical height distance between the airflow port 2032 and the highest position of the pot cavity 301, and a relatively smaller vertical height distance between the airflow port 2032 and the lower port 2021. , even if the air flow diffuses when it is blown and flowing in the air flow cavity 201, the flowing air flow will not diffuse into the pot cavity 301. The diffused air flow will only diffuse at a position above the pot cavity 301, and will not diffuse into the pot cavity 301, nor will it diffuse onto the rice in the pot cavity 301. The air flow can be concentrated in the air flow cavity 201 to cool down and disperse the rice soup bubbles rising in the pot cavity 301, which is equivalent to forming an effect of cold air flow above the pot cavity 301. In this way, the rice soup bubbles in the pot cavity 301 can be quickly defoamed and dispersed, thereby achieving an effective anti-overflow effect. At the same time, when achieving a better anti-overflow effect, the air flow will not contact the rice, so that the rice remains clean and original without any odor.

[0041] In this solution, in order to better guide the airflow, the projection area formed by projecting the guide portion 2041 upward in the vertical direction is formed to cover at least a portion of the edge position of the lower port 2021, thereby guiding the airflow diffusing downward near the edge of the lower port 2021 to flow upward, so that the airflow flowing downward near the position of the lower port 2021 can better enter the upper surface of the guide portion 2041 and be concentrated near the upper surface of the guide portion 2041, and The airflow is guided by the guide part 2041 and flows upward along the upper surface of the guide part 2041. The airflow flowing downward is blocked by the guide part 2041 and the flow direction of the airflow is changed to make the airflow flow upward, thereby effectively preventing the airflow from entering the pot cavity 301 and contacting the rice, and achieving the rapid defoaming and dispersion of the rice soup bubbles in the pot cavity 301, thereby achieving an effective anti-overflow effect. At the same time, the airflow will not contact the rice while achieving a better anti-overflow effect, so that the rice remains clean and original without any odor.

[0042] In this solution, the structure of the guide member 204 is provided with a main body 2042 on the guide member 204, and the upper end of the main body 2042 is installed on the pot cover 2 or on the cavity wall of the airflow cavity 201, and the guide portion 2041 is arranged to be annular in structure around the main body 2042. The guide portion 2041 with an annular structure can be formed to guide the airflow in the entire annular direction, and the guide portion 2041 is arranged to extend upward and be arranged to be inclined upward to guide the airflow to flow upward or obliquely upward, and finally be blown to the position of the lower port 2021 by the airflow blown out of the airflow port 2032, wherein the upward inclined structure of the guide portion 2041 can better guide the airflow to move in the inclined direction, and prevent the airflow from entering the pot cavity 301 downward to contact the rice. Specifically, a guide cavity with an annular structure is formed between the guide portion 2041 and the main body 2042, so that the airflow in the guide cavity flows upward along the guide portion 2041. When the air flow port 2032 moves in the air flow cavity 201 along the inclined direction to the vicinity of the lower port 2021, part of the air flow will flow downward due to collision or failure to enter the lower port 2021 in time. At this time, the air flow enters the guide cavity downward along the extension direction of the main body 2042. After the air flow is concentrated in the guide cavity, it forms a flow upward or obliquely upward along the inclined direction of the guide portion 2041, so that the guide member 204 guides the air flow upward so that the air flow does not enter the pot cavity 301 downward and contact the rice. In the above process, the air flow is concentrated in the guide cavity and guided to flow upward, so that the air flow can be better blown into the lower port 2021 for discharge outward, and the rice soup bubbles in the pot cavity 301 are quickly defoamed and dispersed, thereby achieving an effective anti-overflow effect. At the same time, when achieving a better anti-overflow effect, the air flow will not contact the rice, so that the rice remains clean and original without any odor.

[0043] In this solution, in order to achieve better airflow to cool down, disperse and defoam the rising rice soup bubbles, a plurality of airflow parts 203 are provided on the edge position of the airflow chamber 201 on the annular structure. The plurality of airflow parts 203 blow out airflow in multiple directions from the outer edge position of the airflow chamber 201 toward the lower port 2021 at the middle position or the center position on the annular structure of the airflow chamber 201. The plurality of airflow parts 203 are distributed in an interval structure along the annular direction. The airflows blown out by the plurality of airflow parts 203 are all formed into a structure that flows in an inclined direction toward the position of the lower port 2021, thereby forming a structure for blowing out airflow at multiple different positions within the range of the annular structure formed above the pot cavity 301, thereby achieving cooling, dispersing and defoaming the upward surging rice soup bubbles in the entire annular direction, thereby achieving a better anti-overflow effect.

[0044] In this solution, in order to further prevent the diffused airflow from entering the pot cavity 301 and contacting the rice, at least a portion of the lower end of the guide member 204 is located in the pot cavity 301, so that a larger height distance range can be provided in the vertical direction to guide the diffused airflow and guide it to flow upward. The end position of the guide member 204 in the extension direction is provided above the position of two-thirds from bottom to top on the height distance H0 formed by the pot cavity 301 in the vertical direction. This not only allows the airflow port 2032 and the guide portion 2041 to have a certain height range in the vertical direction to better guide the diffused airflow, but also makes it difficult for rice bubbles to enter the guide cavity during the upward process. Some rice bubbles may surge upward along the outer surface of the guide portion 2041, but will also be cooled, blown away and defoamed by the airflow in time. This not only further prevents the diffused airflow from entering the pot cavity 301 and contacting the rice, but also prevents the rice bubbles from surging into the guide cavity.

[0045] Preferably, the end position of the guide portion 2041 in the extending direction is arranged above a position three-quarters of the height distance H0 formed by the pot cavity 301 in the vertical direction from bottom to top.

[0046] In this solution, in order to better guide the airflow to flow upward, the end position of the guide part 2041 in the inclined direction is set below the airflow outlet 2032, so that the end position of the guide part 2041 has a certain height distance range from the airflow outlet 2032 in the vertical direction, so that the airflow will not be blocked by the guide part 2041 even if there is airflow diffusion when moving along the inclined direction. At the same time, the airflow blown out of the airflow outlet 2032 is not easily blocked by the guide part 2041 and flows downward during the movement in the airflow cavity 201, but will continue to flow along the inclined direction to the position of the lower port 2021. Only near the position of the lower port 2021 will part of the airflow flow downward. This part of the airflow will be redirected by the guide part 2041 to flow upward, and will eventually be driven by the airflow blown out of the airflow outlet 2032 to continue to flow to the position of the lower port 2021 to be discharged outward, thereby achieving a better guiding effect of the airflow.

[0047] Alternatively, in this solution, in order to better guide the airflow to flow upward, the end position of the guide portion 2041 in the inclined direction is set below the airflow outlet 2032 and inside the pot cavity 301. In this way, the end position of the guide portion 2041 has a larger height distance range from the airflow outlet 2032 in the vertical direction, so that the airflow will not be blocked by the guide portion 2041 even if there is airflow diffusion when moving along the inclined direction. At the same time, the airflow blown out of the airflow outlet 2032 is not easily blocked by the guide portion 2041 and flows downward during the process of moving in the airflow cavity 201, but will continue to flow along the inclined direction to the position of the lower port 2021. Only near the position of the lower port 2021 will part of the airflow flow downward. This part of the airflow will be redirected by the guide portion 2041 to flow upward, and will eventually be driven by the airflow blown out of the airflow outlet 2032 to continue to flow to the position of the lower port 2021 to be discharged outward, thereby achieving a better guiding flow effect of the airflow.

[0048] In order to prevent the rice soup from surging into the diversion cavity during the process of being defoamed and diffused, in this solution, a blocking portion 2043 is provided at the edge of the inclined structure of the diversion portion 2041. The blocking portion 2043 also has an annular structure in the annular direction. The blocking portion 2043 is set to be a structure extending horizontally or an inclined structure extending downward, so that when the rice soup in the pot cavity 301 surges upward, the blocking portion 2043 forms a blocking structure for the surging rice soup. The blocking portion 2043 is directed away from the diversion cavity. The blocking portion 2043 extends in the direction of the flow portion 2041, or may extend in the direction of the airflow port 2032. The extended blocking portion 2043 forms a blocking structure in the vertical direction. When the rice soup bubbles continue to flow upward along the guide portion 2041 during the process of being cooled and blown away to defoam, they can be blocked by the blocking portion 2043. The rice soup bubbles blocked by the blocking portion 2043 will fall back downward and be continuously blown by the airflow to be cooled, defoamed and blown away, thereby further improving the defoaming effect of the rice soup bubbles and improving the effect of preventing the rice soup bubbles from overflowing.

[0049] In this solution, since the airflow cavity 201 is annular in structure, airflows in different directions will collide when flowing to the vicinity of the lower port 2021, causing part of the airflow to flow downward. In order to better guide the part of the airflow to flow downward and redirect it to flow upward, a guide portion 20421 with an arc-shaped structure in the vertical direction is provided on the main body 2042 to guide the airflow to flow downward along the outer surface of the arc-shaped structure in the vertical direction, and the guide portion 20421 is set to be annular in structure. The guide portion 20421 is annular in structure. The airflow flowing in different directions to the vicinity of the lower port 2021 is guided in the annular direction, and the airflow is guided to flow downward along the arc structure of the guide portion 20421 and enter the guide cavity. The airflow entering the guide cavity will be redirected by the guide portion 2041 to flow upward, and the airflow blown out by the airflow port 2032 is blown to the position of the lower port 2021 to be discharged outward through the lower port 2021. Among them, the guide portion 20421 is provided with multiple guide ports 20422, multiple guide ports 20423, and multiple guide ports 20424. The openings 20422 are spaced and distributed along the annular direction, and a plurality of drainage openings 20422 are formed at a plurality of positions in the annular direction to allow the airflow to flow through, and the drainage openings 20422 are arranged to be connected inwardly with the lower opening 2021 and to be connected outwardly with the airflow cavity 201, so that the airflow flows from the airflow cavity 201 through the drainage openings 20422 into the position of the lower opening 2021, and the airflow blown out of the airflow opening 2032 is blown in an oblique direction in the airflow cavity 201, and the airflow is blown onto the drainage portion 20421. At the same time, part of the airflow enters the lower port 2021 through the drainage port 20422 and is discharged outward, and part of the airflow flows downward on the arc structure of the drainage portion 20421 and enters the guide cavity, and is concentrated in the guide cavity and redirected by the guide portion 2041 to flow upward, and then is blown to the drainage portion 20421 by the airflow. In this process, the airflow will not enter the pot cavity 301 to contact the rice, so that the airflow can be better discharged, and can be better guided and finally discharged outward through the lower port 2021.

[0050] Optionally, the drainage port 20422 is configured to have an elliptical structure, with the long side of the drainage port 20422 in the vertical direction and the short side of the drainage port 20422 in the annular direction, so that the airflow can better enter the lower port 2021.

[0051] In order to further prevent the air flow from being blown into the pot cavity 301 and contacting the rice, in this solution, a drainage cavity 20423 is provided in the main body 2042. The projection area formed by projecting the drainage cavity 20423 upward in the vertical direction constitutes a covering structure for the lower port 2021. The drainage cavity 20423 is mainly used to collect the downward-flowing air flow. It can be understood that when the air flow blows to a position near the lower port 2021, at this time, due to the collision between different air flows in the annular direction and the air flow that does not enter the lower port 2021 in time will be blocked to change the flow direction and flow downward. The setting of the drainage cavity 20423 allows the downward-flowing air flow to enter the drainage cavity 20423 without diffusing into the pot cavity 301, thereby achieving the air flow to be concentrated after entering the drainage cavity 20423 and finally flow upward to enter the lower port 2021 for discharge outward, which can effectively prevent the air flow from being blown into the pot cavity 301 and contacting the rice.

[0052] Among them, the specific structural part of the drainage cavity 20423 is that the upper end position of the drainage cavity 20423 is set to be connected with the drainage port 20422 and the lower port 2021, so that the airflow entering the position near the lower port 2021 through the drainage port 20422 and the airflow that does not enter the lower port 2021 in time at the position of the lower port 2021 can flow downward into the drainage cavity 20423, and the lower end position of the drainage cavity 20423 is set to be a closed structure that is not connected to the airflow cavity 201 or the pot cavity 301, so that the airflow entering the drainage cavity 20423 can only flow upward into the lower port 202 1 position, when the downward-flowing airflow is concentrated in the drainage chamber 20423, it will be blocked by the closed structure at the lower end of the drainage chamber 20423 as it flows downward, so that the airflow will flow upward, and after being blocked, it will enter the lower port 2021 upward to be discharged outward. At the same time, the drainage port 20422 will continue to enter the airflow to blow toward the lower port 2021, so that the airflow in the drainage chamber 20423 will not diffuse outward through the drainage port 20422, but will be concentrated to enter the lower port 2021 upward to be discharged, thereby effectively preventing the airflow from being blown into the pot cavity 301 and contacting the rice.

[0053] Optionally, the main body 2042 is configured to have a hollow structure, and the hollow structure is used to form a cavity of the drainage cavity 20423, thereby concentrating the downward-flowing airflow.

[0054] Anything not mentioned in this plan can be achieved by adopting or drawing on existing technologies.

[0055] Working principle: The electric rice cooker of this scheme is mainly used for cooking rice, especially for cooking porridge and rice gruel. When the pot cover 2 forms a closed structure for the pot cavity 301, the pot cover 2 is closed on the pot body 1 to form a closed structure for the pot cavity 301. At this time, the electric rice cooker can start working, and the airflow device in the pot cover 2 works to generate airflow into the airflow cavity 201. The airflow blows and flows in the airflow cavity 201 to cool down and blow away the rice soup bubbles rising in the pot cavity 301, thereby achieving an overflow prevention effect. At the same time, the airflow will eventually be discharged to the outside of the electric rice cooker through the exhaust channel 202. During the process of the airflow blowing out in the airflow cavity 201, the airflow will not diffuse into the pot cavity 301, so that the airflow will not contact the rice in the pot cavity 301. The partially diffused airflow and the downward-flowing airflow will eventually flow upward under the guidance of the guide member 204, and finally be discharged outward through the airflow channel 2031. During the whole process, the odor or particulate matter in the airflow will not come into contact with the rice, so that the rice will not be contaminated by the airflow. Especially when the rice cooker is working in an environment with thick oil smoke, if the airflow inhaled by the airflow device blows onto the rice in the pot cavity 301, the rice will be contaminated by the oil smoke in the airflow, resulting in odor, etc., making the rice lose its original flavor and initial clean state. The structure of this solution can prevent the airflow from coming into contact with the rice during the overflow prevention process, and the rice can maintain its original flavor. This solution can effectively prevent odor, particulate matter, etc. in the airflow from entering the rice.
