Detailed Description

The following is a description of the technical solution of the present invention in steps with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Referring to fig. 1-8, fig. 1-8 show embodiments of the present invention.

The embodiment shows steam heating cooking appliances, specifically steam heating electric rice cooker, the electric rice cooker includes a body 10, a pot body 20, a pot cover 30 covering the pot body 20, a steam generating device 40 is arranged in the body 10, a steam inlet hole 31 and a steam outlet hole 32 are arranged on the pot cover 30, a steam guide pipe 50 is arranged on the steam inlet hole 31, the steam guide pipe 50 has a connecting part 51 close to the end of the pot cover 30 and an air outlet part 53 far away from the end of the pot cover 30 , an air outlet 531 is arranged on the air outlet part 53, and the pipe diameter of the air outlet part 53 is smaller than that of the connecting part 51.

During cooking, the pot body 20 is placed on the machine body 10, the pot cover 30 on the pot body 20 and the pot body 20 are covered to form a cooking cavity, the steam generating device 40 in the machine body 10 works to generate steam, the steam reaches the pot cover 30 through the steam pipeline 41 and enters the steam guide pipe 50 through the steam inlet hole 31 in the pot cover 30, and finally the steam guide pipe 50 introduces the steam into the cooking cavity to heat food materials in the cooking cavity.

Specifically, during cooking, the steam guide pipe 50 extends below the liquid level in the cooking cavity. Taking cooked rice as an example, when the steam is discharged from the steam guide pipe 50, high-temperature bubbles are formed, the high-temperature bubbles float in the rice milk, and the rice milk is fully contacted with the rice milk in the floating process and transfers heat to the rice milk, so that the rice milk is heated and boiled. In addition, in the floating process, the whole rice milk can form rolling action due to the driving of the bubbles, so that the rice milk far away from the steam guide pipe 50 can be heated by contacting the flowing rice milk with the high-temperature bubbles.

The process of the steam discharging out of the steam guide pipe 50 is that the steam at the air outlet 531 is pushed by the air pressure in the steam guide pipe 50, so that the steam at the air outlet 531 overcomes the rice milk hydraulic pressure and enters the rice milk. Therefore, the air pressure in the steam guide pipe 50 determines the distance of the bubbles from the air outlet 531, and the bubbles can reach a place farther from the steam guide pipe 50 to start floating up the bubbles the greater the air pressure in the steam guide pipe 50. It should be noted that the distance at which the bubbles escape from the air outlet 531 refers to the moving distance of the bubbles in the air outlet direction of the air outlet 531, i.e., the distance of the bubbles from the steam guide pipe 50.

In this embodiment, the pipe diameter of steam guide pipe 50 is very little compared in the internal diameter of whole culinary art chamber, the bubble is far away from the distance of gas outlet 531, the movement track of bubble is big more, the bubble is more to the scope that the rice milk promoted, the range of rice milk motion is bigger, it is more to form mobile rice milk, the effect that the rice milk rolled is better, thereby make the rice milk at each position in the culinary art intracavity can both flow and can carry out the contact with the bubble and be heated, the rice milk in the culinary art intracavity is heated more evenly, it is shorter during the culinary art, the rice taste of cooking out is better.

When the air pressure in the steam guide pipe 50 is small, steam is separated from the air outlet 531 to form bubbles to float upwards, only the rice milk at the accessory of the steam guide pipe 50 flows to be heated, the rice milk far away from the steam guide pipe 50 is heated a little, and therefore the rice milk in the cooking cavity is heated unevenly, and the taste of cooked rice is not ideal enough.

In this embodiment, the steam guide pipe 50 has a connection part 51 near the pot cover 30 end and an air outlet part 53 far from the pot cover 30 end, the pipe diameter of the air outlet part 53 is smaller than that of the connection part 51, the air outlet 531 is arranged on the air outlet part 53. the steam guide pipe 50 into which the steam enters from the steam inlet hole 31 on the pot cover 30 firstly enters the connection part 51, then passes through the air outlet part 53 and is discharged out of the steam guide pipe 50 from the air outlet 531 on the air outlet part 53. because the pipe diameter of the air outlet part 53 is smaller than that of the connection part 51, the flow rate of the steam is increased when the steam enters from the connection part 51 to the air outlet part 53, and the steam pressure in the air outlet part 53 is increased.

In order to make the steam flow from the connecting portion 51 to the air outlet portion 53 smoother, in the present embodiment, a transition portion 52 is disposed between the connecting portion 51 and the air outlet portion 53, and the pipe diameter of the transition portion 52 is gradually reduced from the connecting portion 51 to the air outlet portion 53. The transition part 52 enables the whole steam guide pipe 50 to be in a conical drop pipe shape, namely, the pipe wall between the connecting part 51 and the air outlet part 53 is an inclined wall, when steam flows to the air outlet part 53 from the connecting part 51, no large flow resistance exists, the flowing smoothness is guaranteed, and the air outlet effect of the steam guide pipe 50 is good.

, when the cover 30 and the body 20 are covered, the steam guide tube 50 is located in the central area of the cooking cavity of the body 20. when the steam guide tube 50 is located in the central area of the cooking cavity of the body 20, the steam is scattered from the center of the cooking cavity for heating, the rice milk in the cooking cavity is heated more evenly, and no heating dead angle exists.

In the present embodiment, the bottom of the outlet part 53 of the steam guide pipe 50 is closed, and the outlet 531 is provided on the sidewall of the outlet part 53. The steam guide pipe 50 is inserted into the rice milk when the pot cover 30 is closed with the pot body 20, and the steam guide pipe 50 is subjected to resistance of the rice milk in the process of being inserted into the rice milk, and the stress surface of the steam guide pipe is mainly the bottom of the steam guide part, namely the bottom of the air outlet part 53. If the air outlet 531 is arranged at the bottom of the air outlet part 53, rice grains in the rice milk are easily blocked on the air outlet 531 in the process of inserting the steam guide pipe 50 into the rice milk, and the normal air outlet of the steam is influenced.

In this embodiment, the bottom of the steam guide pipe 50 is closed, and the air outlet 531 is disposed on the sidewall of the air outlet portion 53, so that rice grains in the rice milk can be effectively prevented from entering the steam guide pipe 50, and the rice grains in the rice milk are prevented from being stuck at the air outlet 531.

, if the air outlet 531 of the air outlet part 53 is located 1-3 cm. below the liquid level of the cooking cavity, if the air outlet 531 of the air outlet part 53 is located less than 1cm below the liquid level, the sprayed steam impacts the liquid level when the steam is introduced too fast, the liquid at the air outlet 531 may scatter around, the steam discharged from the air outlet 531 cannot fully contact with the liquid, the cooking time is slow, if the air outlet 531 of the steam guide pipe 50 is located more than 3cm below the liquid level, the steam forms a large amount of foam below the liquid level, the foam rises above the liquid level from the liquid level, and the inner wall of the pot body 20 above the liquid level is adhered with a large amount of food to be cooked, so that the user experience is affected.

Step , the aperture of air outlet 531 is set between 1mm to 3mm, for example, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, when the aperture of air outlet 531 is smaller than 1mm, the air outlet pressure at air outlet 531 is too large, the noise generated at air outlet 531 is large, when the aperture of air outlet 531 is larger than 3mm, the aperture of air outlet 531 is too large, rice grains in rice milk easily enter into steam guide tube 50, resulting in difficulty in cleaning, in addition, rice grains in rice milk are also easily stuck on air outlet 531, which affects normal air outlet of air outlet 531.

In the present embodiment, after the steam enters the steam guide pipe 50 through the steam pipeline 41, the steam flows in along the radial direction of the steam guide pipe 50. since the bottom of the steam guide pipe 50 is closed, the air outlet 531 is located at the side of the air outlet portion 53, the flowing-in steam meets the inner side of the bottom wall of the air outlet portion 53 and is turned to flow back, and finally flows out of the air outlet 531 under the action of the air pressure, obviously, the bottom wall of the air outlet portion 53 has -determined reduction effect on the impact force of the steam, which results in -determined attenuation of the force of the steam ejected from the air outlet 531.

Preferably, in this embodiment, a guiding structure 533 is disposed between the inner side of the bottom wall of the air outlet portion 53 and the inner side of the side wall of the air outlet portion 53, the guiding structure 533 may be a connecting arc surface between the inner side of the bottom wall of the air outlet portion 53 and the inner side of the side wall of the air outlet portion 53, or a connecting inclined surface between the inner side of the bottom wall of the air outlet portion 53 and the inner side of the side wall of the air outlet portion 53, when the inrush steam blocks the bottom wall of the air outlet portion 53, the guiding structure 533 guides the steam flowing back and flows into the air outlet 531 to be discharged.

Step , the number of the air outlets 531 is multiple, and the air outlets 531 are circumferentially arranged along the circumferential direction of the air outlet part 53. thus, when the steam is sprayed out from the air outlets 531, the steam is in an annular spraying shape, the rice milk in each direction in the cooking cavity can be driven by the air bubbles, the rolling effect is formed, the rolling effect of the rice milk is good, and the rice milk is uniformly heated.

After the steam is sprayed from the air outlets 531, the air pressure of the steam is greater than the pressure of the rice milk, air bubbles expand, the expansion of the air bubbles is increased, the occupied space of the air bubbles is increased, the air bubbles sprayed from the adjacent air outlets 531 collide with each other under the condition of smaller space, so that the elastic force of part of spraying is counteracted, the air bubbles cannot reach the area far away from the air outlets 531, and the uniform heating of the rice milk is not facilitated.

In this embodiment, the adjacent air outlets 531 are arranged in a staggered manner in the pipe diameter direction of the steam guide pipe 50, and the staggered arrangement means that the height positions of the adjacent air outlets 531 are not and the adjacent air outlets 531 are not overlapped or not overlapped completely in the radial direction of the steam guide pipe 50, so that the bubbles generated by the adjacent air outlets 531 can be ejected in a staggered manner from top to bottom in , and the collision between the bubbles is reduced, in addition, the area of the air outlet 531 on the air outlet part 53 can be increased in , so that more air outlets 531 are arranged on the air outlet part 53, and in , the steam is ejected from the air outlets 531 in a staggered manner from top to bottom, and the rice milk is pushed to flow in two directions from top to bottom, so that the rice milk forms an interactive convection effect, the rice milk rolls more sufficiently, and the rice milk is heated more.

When the air outlets 531 are arranged in a vertically staggered manner, steam flows to the air outlets 531 above the steam guide pipe 50 after entering the steam guide pipe 50, part of the steam is firstly discharged from the air outlets 531 at the upper part, the rest of the steam does not flow until the discharged steam flows continuously, and the steam is discharged from the air outlets 531 below the steam guide pipe 50. obviously, the pressure on the steam discharged from the air outlets 531 above the steam guide pipe 50 is large, the spraying effect is good, the pressure on the steam discharged from the air outlets 531 below the steam guide pipe 50 is small, and the spraying effect has -determined attenuation.

In the embodiment, the projections of the air outlets 531 arranged in the air outlet part 53 in a vertically staggered manner on the circumference of the air outlet part 53 at least are partially overlapped, so that the area of the air outlets 531 arranged on the air outlet part 53 can be increased in the aspect of , and in addition, in the aspect of , because the height difference of the vertically staggered air outlets 531 is not large, the attenuation of the jet force of the steam jetted by the air outlets 531 below is small, and then the effect that the steam jetted by the staggered air outlets 531 pushes the rice milk to form the interactive convection can be ensured.

In this embodiment, the steam guide pipe 50 is inserted into the rice milk during cooking, so as to make the process of inserting the steam guide pipe 50 into the rice milk more smooth, and also to make the lid 30 open after the rice is cooked, and the influence of the steam guide pipe 50 on the smoothness of the rice after pulling out the rice is small, the steam guide pipe 50 of this embodiment is provided with an avoiding structure 532 between the bottom wall and the side wall of the air outlet 53, the avoiding structure 532 is used to reduce the resistance of inserting the steam guide pipe 50 into the rice milk, and in addition, is used to push the solid food material to move through the avoiding structure 532 when cooking the solid food material such as meat and bone, and a path channel is opened for inserting the steam guide pipe 50 into the cooking cavity.

In , the avoiding structure 532 may be an arc transition portion 52 between the bottom wall and the side wall of the air outlet portion 53, the arc transition portion 52 disposed between the bottom wall and the side wall of the air outlet portion 53 makes the bottom of the steam guide tube 50 approximately spherical, and when the spherical bottom contacts the solid food material, the food material will receive a component force moving to the side portion, so that the steam guide tube 50 can push away the food material to be inserted into the cooking cavity, thereby ensuring that the steam guide tube 50 can be smoothly inserted into the cooking cavity, the lid 30 can be smoothly covered with the pot body 20, and the use by the user is facilitated.

In another embodiments, the avoiding structure 532 may be a slope transition portion 52 formed by directly connecting the bottom wall and the side wall of the air outlet portion 53, the slope transition portion 52 is directly formed on the bottom wall and the side wall of the air outlet portion 53, when the steam guide pipe 50 is inserted into the rice milk, the rice milk is separated along the slope transition portion 52, the slope transition portion 52 serves to separate the liquid level, and the steam guide pipe 50 is less resistant to being inserted into the cooking cavity.

In addition, the arrangement of the avoiding structure 532 enables the overall external contour curve of the steam guide pipe 50 to be softer and smoother, the appearance is more attractive, and in addition, when the steam guide pipe 50 is inserted into rice milk or pulled out of rice, the process is smoother and the influence on the flatness of the rice is small in .

In this embodiment, the steam guide pipe 50 is sealed and fixed with the pot cover 30 through the connection portion 51, and the connection manner is detachable, such as fastening or clamping, so that the user can conveniently detach the steam guide pipe 50 and clean the steam guide pipe 50.

In addition, when cooking is completed, the operation of the steam generating device needs to be stopped before the cover is opened, the steam generating device 40 stops continuously delivering high-temperature steam to the steam pipeline 41 after stopping operation, the heat preservation performance of the steam pipeline 41 cannot be objectively guaranteed to be perfect, and the heat of the high-temperature steam in the steam pipeline 41 gradually loses. Therefore, high-temperature steam in the steam pipeline 41 can be gradually condensed, the air pressure in the steam pipeline 41 is reduced, when the air pressure in the steam pipeline 41 is smaller than the air pressure in the cooking cavity, the pressure difference between the inside and the outside of the steam pipeline 41 can squeeze soup and the like in the cooking cavity into the steam pipeline 41, the phenomenon of suck-back of the steam pipeline 41 is formed, and great inconvenience is brought to cleaning of a user.

In order to solve the above problem, in the present embodiment, the anti-suck-back hole 54 is formed on the steam guide pipe 50, the anti-suck-back hole 54 is formed above the liquid level of the cooking cavity, the anti-suck-back hole 54 is communicated with the steam pipeline 41, when the steam generating device 40 stops working and the inside of the steam pipeline 41 is in a negative pressure state, the gas at the upper part of the cooking cavity will enter the steam pipeline 41 prior to the liquid at the bottom of the cooking cavity, so as to balance the pressure difference between the inside and the outside of the steam pipeline 41, thereby preventing the liquid in the cooking cavity from being sucked back into the steam.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
