AI Technical Summary
During the working process, the steam is sprayed with water, resulting in waste of heat, insufficient water absorption of food, and a decrease in the quality of cooking. The discharged steam condenses into liquid or soup sticks to the lid of the pot, causing the rice cooker to stain.
A new type of rice cooker exhaust hole is designed, including the exhaust port and the exhaust chamber of the upper half. The exhaust port is inclined 60 degrees upwards, and the lower half is equipped with an air inlet port, a water return valve and an air inlet cavity. The steam is discharged after condensing through the inlet cavity and the exhaust chamber twice. The water return valve causes the condensation water to flow back into the pot.
It effectively eliminates the phenomenon of water spraying during the working process of the rice cooker, reduces power consumption, and the cooked rice is softer and more delicious, and the exhaust port is rotatable, making it safer and more reliable to use and easy to clean.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of household electric cookers, in particular to a novel exhaust hole for an electric rice cooker. Background Art
[0002] The steam exhaust method of the existing electric rice cooker is straight exhaust and straight out when working, and the steam exhaust port is round at the bottom and flat at the top. This structure will cause the steam to be ejected together with the water in the pot during the operation of the electric rice cooker, which not only wastes heat and thus consumes more electricity, but also causes the food in the pot to absorb insufficient water, and the cooked rice is easy to be sandwiched and undercooked, and in more serious cases, it will cause the pot to burn, which causes a certain amount of food waste. In addition, the exhaust port with a round bottom and a flat top structure will also cool the discharged steam into liquid or soup that adheres to the surface of the pot cover, dirtying the surface of the electric rice cooker and causing a lot of trouble for consumers. Summary of the invention
[0003] In view of the deficiencies in the prior art, the utility model provides a novel electric rice cooker exhaust hole which has a simpler structure, is easier to process and assemble, improves the quality of rice cooking, and is easy to clean.
[0004] The utility model comprises an electric rice cooker lid and an exhaust hole, wherein the upper part of the exhaust hole is provided with an exhaust port and an exhaust cavity, the exhaust port is communicated with the exhaust cavity, the exhaust port opens obliquely upward, and the upper part of the exhaust hole is connected with an upper buckle of the electric rice cooker lid; the lower part of the exhaust hole is provided with an air inlet and a water reflux valve and an air inlet cavity communicated with the former two, a baffle is provided above the air inlet, a channel is provided on the top of the air inlet cavity and communicated with the exhaust cavity, and the channel is not opposite to the air inlet in a vertical direction.
[0005] The upper part of the exhaust hole is in the shape of a hemisphere, connected to the upper part of the electric rice cooker lid through a middle elastic buckle, and can rotate, and the exhaust port is inclined upward by 60 degrees. The opening shape of the air inlet is set to be a semicircular shape, and the baffle is also set to be a semicircular shape of the same size. The air inlet, the water reflux valve bracket, the air inlet cavity, the channel and the baffle are all connected to the cover body of the electric rice cooker lid.
[0006] Beneficial effects: 1. Prevent water spraying during operation of the rice cooker; 2. Part of the steam and heat energy reflux to form a small amount of pressure, making the cooked rice softer and more delicious, reducing power consumption; 3. The rotatable steam port is safer and more reliable to use. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 This is a cross-sectional view of the structure of the utility model;
[0008] Figure 2 This is the appearance diagram of the utility model;
[0009] Figure 3Schematic diagram of the exhaust cavity structure of the present utility model. Specific embodiments
[0010] The present utility model will be further described below with reference to the accompanying drawings.
[0011] In the accompanying drawings, the present utility model mainly consists of a rice cooker lid 1, an exhaust hole 2, an exhaust port 3, an exhaust cavity 4, an air inlet 5, a water return valve 6, an air inlet cavity 7, a baffle 8, a channel 9 and an elastic buckle 10.
[0012] As Figure 1 and 2 shown, the present utility model includes a rice cooker lid 1 and an exhaust hole 2. The upper half of the exhaust hole 2 is provided with an exhaust port 3 and an exhaust cavity 4 communicating with the exhaust port 3. The opening direction of the exhaust port 3 is obliquely upward. The upper half of the exhaust hole 2 is snap-connected to the upper part of the rice cooker lid 1; the lower half of the exhaust hole 2 is provided with an air inlet 5, a water return valve 6 and an air inlet cavity 7 communicating with the former two. A baffle 8 is arranged above the air inlet 5. A channel 9 is arranged at the top of the air inlet cavity 7 and communicates with the exhaust cavity 4. The channel 9 is not opposite to the air inlet 5 in the vertical direction.
[0013] When the rice cooker heats up to generate steam, the steam will enter the air inlet cavity 7 along the air inlet 5 and rebound completely and diffusely through the baffle 8. When the air inlet cavity 7 is filled with steam and generates pressure, the steam in the air inlet cavity 7 will then enter the exhaust cavity 4 along the channel 9. When the exhaust cavity 4 is filled with steam and generates pressure, it will then be discharged obliquely upward from the exhaust port 3 away from the lid. Obviously, there are 4 effects: 1. The gas coming out of the exhaust port 3 is discharged after being fully condensed twice in the exhaust cavity 4 and the air inlet cavity 7; 2. Especially, the exhaust cavity 4 is a structure protruding from the lid, and the effect of condensing steam with low temperature is good; 3. The air inlet 5 and the channel 9 are arranged not to be opposite in the vertical direction and the baffle 8 are provided to prevent the steam at the air inlet 5 from directly entering the exhaust cavity or some steam from directly spraying out with water from the exhaust port 3; 4. The water condensed from the two cavities flows back into the rice cooker inner pot through the water return valve 6. The above 4 effects effectively and completely prevent the phenomenon of water spraying during the working process of the rice cooker and avoid the appearance of cooking stains on the lid. At the same time, compared with the existing technology, the exhaust of this utility model adds 3 folds and two exhaust (air inlet) cavities, so that a partial exhaust reflux is generated during the working process of the rice cooker to form a trace amount of pressure, making the cooked rice softer and more delicious; in addition, part of the heat also flows back with the condensed water in the two cavities through the water return valve 6, further reducing power consumption.
[0014] As Figure 3As shown in the figure, for aesthetic purposes and to enhance the heat dissipation effect, the upper half of the exhaust hole 2 is designed in the shape of a hemisphere. It is connected to the upper surface of the rice cooker lid 1 by a middle elastic buckle 10 and can rotate. This structure not only facilitates disassembly, assembly, and cleaning, but more importantly, the rotatable exhaust port 3 can change the steam discharge direction as required, making it safer and more reliable to use. The exhaust port 3 is most aesthetically pleasing and practical when it is tilted upward by 60 degrees.
[0015] To facilitate the more uniform and rapid diffusion of steam in the intake cavity, the opening shape of the intake port 5 is set as a semi-circular shape, and the baffle 8 is also a semi-circle of the same size. The intake port 5, the bracket of the water return valve 6, the intake cavity 7, the channel 9, and the baffle 8 are all assembled from injection-molded parts of the rice cooker lid 1 and are integrated with the lid, eliminating the need for additional processing. For the entire exhaust hole, only the air-blocking rubber pad of the water return valve 6 and the upper half sphere of the exhaust hole need to be injection-molded separately, which facilitates disassembly, assembly, and cleaning, and also greatly saves materials and assembly time.
