Detailed Description

The following detailed description is made of specific embodiments of the present invention with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The present embodiment provides a steam rice cooker, as shown in fig. 1, including a frame 100 and a container. The container comprises a container body 200 and a cover body 300 covering the container body 200, wherein the cover body 300 is provided with a steam input port 310. The frame body 100 comprises a bearing part 110, a supporting part 120 formed by upwards extending the bearing part 110, and a top part 130 extending from the supporting part 120 to the upper part of a container, wherein the top part 130 and the bearing part 110 form an open container taking and placing space, the container is placed on the bearing part 110, a steam generator for leading steam into the container is arranged in the supporting part 120 or the top part 130, a steam outlet 131 of the steam generator is in butt joint with a steam input port 310 of the container, a water tank is further arranged to be connected with the steam generator, and water for cooking is stored in the water tank. The water in the water tank is pumped into the steam generator, the steam generator heats the water to form steam, and the steam enters the container body 200 through the steam outlet 131 and the steam input port 310 to steam-cook the food in the container body 200.

As shown in fig. 2-3, the cover 300 has a steam connector 320 protruding upward, the steam connector 320 is provided with a steam input port 310, and the steam outlet 131 is located on the top 130 and abuts against the steam input port 310 of the steam connector 320. The outer diameter of the steam joint 320 is gradually reduced from bottom to top.

When a user uses the container, the user can easily open the cover 300 by grasping the steam connector 320 with hands, steam enters the container through the steam input port 310 of the steam connector 320 during cooking, and immediately after the cooking is finished, the steam connector 320 is at a high temperature, so that the user can easily scald the user's hands by touching the steam connector 320 for a long time.

The outer diameter of the steam joint 320 is gradually reduced from bottom to top, when fingers grab the side wall of the steam joint 320, the clamping force of the fingers on the steam joint 320 can be divided into a first component force perpendicular to the side wall of the steam joint 320 and a second component force parallel to the side wall of the steam joint 320, when the first component force is larger than the maximum static friction force between the fingers and the side wall of the steam joint 320, the fingers can slide upwards along the side wall of the steam joint 320 and finally break away from the steam joint 320, the outer diameter of the steam joint 320 is gradually reduced from bottom to top, so that the fingers are not easy to grab the steam joint 320, a user is prevented from opening the cover body 300 by grabbing the steam joint 320, the phenomenon that the user contacts the steam joint 320 in a high-temperature state for too long time is avoided, the possibility of scalding the user is reduced, and the safety of the steam cooking container is improved.

As shown in fig. 4, the side wall of the steam joint 320 is an inclined plane 321 which extends from bottom to top and inclines inwards, the inclination angle from the lower end to the upper end of the side wall of the steam joint 320 is consistent, the inclined plane has a simple structure and is convenient to process, and the junction of the side wall and the top wall of the steam joint 320 is provided with a fillet transition to avoid hurting the hand of a user by the sharp-horn-shaped junction.

The included angle between the side wall of the steam joint 320 and the vertical line is greater than or equal to 12 degrees. The larger the angle between the side wall of the steam joint 320 and the vertical line is, the larger the first component force is, the smaller the second component force is, the smaller the maximum static friction which can be formed between the fingers and the side wall of the steam joint 320 is, the less easily the fingers can grasp the steam joint 320, and the higher the safety of the container is. In a specific application, it is not preferable that the larger the included angle is, when the included angle between the sidewall of the steam joint 320 and the vertical line is the largest, the steam joint 320 is tapered to be unfavorable for sealing and butting with the top 130, the top 130 of the steam joint 320 needs to have a plane capable of sealing and butting with the top 130, so that the portion of the steam joint 320 protruding from the upper surface of the cover 300 is preferably in a truncated cone shape, and the included angle between the sidewall of the steam joint 320 and the vertical line is preferably 60 °, such as 15 °, 30 °, 40 ° or 45 °.

The side wall surface of the steam header 320 is smooth. Therefore, the maximum static friction between the fingers and the steam joint 320 is small, so that the fingers are not easy to grasp the steam joint 320, and the safety is improved. The smoother the surface of the side wall, the smaller the corresponding included angle between the side wall and the vertical line can be correspondingly adjusted.

The vapor connector 320 has a sidewall roughness of less than 2 microns, such as 1.5 microns, 1 micron. The side wall of the steam joint 320 with roughness is smooth, fingers are not easy to grasp the steam joint 320, and safety is improved.

In other alternative embodiments, the sidewall of the steam connector 320 has multiple inclined planes from bottom to top, and the multiple inclined planes are all inclined inwards from bottom to top. This is an alternative to the design of steam junction 320, increasing the flexibility of the design of steam junction 320. For example, the sidewall of the steam connector 320 is provided with two sections of slopes, including an upper section slope and a lower section slope, and the included angle between the upper section slope and the vertical line is larger than the included angle between the lower section slope and the vertical line. When the fingers are in a clamping state, the lower end parts of the contact surfaces of the fingers and the steam joint 320 are bent back to the steam joint 320 from top to bottom, the acting force of the fingers on the lower section inclined plane is very limited, and the included angle between the upper section inclined plane and the vertical line is larger, so that the fingers are more difficult to grasp the steam joint 320. Due to the structural characteristics of the fingers, a small section of the lower end of the side wall of the steam connector 320 can be vertical.

In still other alternative embodiments, the sidewalls of the steam junction 320 are convex arcs. The included angle between the tangent line of the arc surface and the vertical line is gradually increased from bottom to top, so that the fingers are more difficult to grasp the steam joint 320. Of course, the sidewall of the steam connector 320 may also be concave.

The height of the steam joint 320 protruding from the cover 300 is less than or equal to 10mm, such as 5mm, 7mm, 8mm, the smaller the protruding height of the steam joint 320 is, the smaller the grabbing force surface formed by fingers and the steam joint 320 is, the less easily the steam joint 320 is grabbed, and the safety is improved.

As shown in fig. 1 and fig. 5, the top 130 has an operation position 132, and the cover 300 has a clearance structure corresponding to the operation position 132. When cooking is completed and the container needs to be taken out of the housing 100, the top 130 needs to be lifted, and the top 130 can be lifted by inserting a finger into the operating position 132 and applying an upward force. The arrangement of the clearance structure enables a larger operation space to be formed between the operation position 132 and the cover body 300, so that the fingers can fully extend into the operation position 132, the fingers can fully contact with the top 130, the phenomenon that the fingers slip with the top 130 due to the fact that the fingers are embedded into the operation position 132 due to too small depth is avoided, and the operation of lifting the top 130 is facilitated.

As shown in fig. 1, the rear end of the top 130 is rotatably connected to the supporting portion 120, and the operating position 132 is disposed at the front end of the top 130. Therefore, the operation position 132 is far away from the rotation fulcrum, a large force arm can be formed, the lifting operation of the top portion 130 is more labor-saving, the lifting operation of the top portion 130 is convenient, and the force application direction is consistent with the rotation direction of the top portion 130. In other alternative embodiments, the top portion 130 may also be vertically lifted, and the top portion 130 is vertically slidably connected to the supporting portion 120.

As shown in fig. 1, 2 and 5, the clearance structure is a sinking platform 330 on the cover 300. The sinking platform 330 is recessed relative to its periphery, so that the upper surface of the cover 300 corresponding to the operation position 132 moves downward, and the cover 300 and the top 130 form a larger space at the operation position 132, which is convenient for the fingers to insert into the operation position 132 to lift the top 130. This space-avoiding structure can be applied to the cover 300 having an arch shape, as well as to the cover 300 having a horizontal shape. In other alternative embodiments, when the cover 300 is arched, that is, the cover 300 is arched upward from the periphery to the center, the local position of the cover 300 is horizontally disposed to form the clearance structure. For the arched cover 300, the larger the arching length is, the higher the arching height is, and the cover 300 corresponding to the operation position 132 is horizontally arranged, so that the arching at the position can be avoided from being too high, the height of the position is reduced to form a yielding space, and the space for inserting fingers into the operation position 132 is increased.

As shown in fig. 2 to 3, the steam connector 320 is disposed on the stage 330, and the steam connector 320 protrudes upward with respect to the surface of the stage 330. Since the distance between the top portion 130 and the carrying portion 110 is fixed, the steam connector 320 is moved downward relative to the rest of the container, thereby increasing the capacity of the container. In other alternative embodiments, the steam connector 320 may be disposed outside the sinking platform 330, since the steam connector 320 needs to be abutted against the top portion 130, the distance from the bearing portion 110 to the steam connector 320 is fixed, and the steam connector 320 is located outside the sinking platform 330, so that the cover 300 needs to be moved downward relative to the frame 100, which reduces the overall capacity of the container.

As shown in fig. 1, the clearance structure extends to the outside of the top portion 130, in this embodiment, the sinking platform 330 extends forward beyond the front end of the top portion 130, and the front end of the top portion 130 is the left end in fig. 1, so that the fingers can be inserted into the operation position 132 more smoothly, and the feeling of oppression is reduced.

As shown in fig. 1 and 2, the steam input port 310 is located at the center of the cover 300, and the clearance structure is symmetrically arranged about the steam input port 310. The front and back symmetry of the cover body 300, the assembly direction of the cover body 300 and the container body 200 is more random, the cover body 300 does not need to be covered according to the unique installation direction, the flexibility of the cooperation of the cover body 300 and the container body 200 is improved, the convenience of operation is improved, and the situation that the clearance structure cannot correspond to the operation position 132 is avoided. In other alternative embodiments, the clearance structure may also extend only to the front end, and due to the structural characteristics of the bearing portion 110, the assembly direction of the container and the frame body 100 is unique, so that the cover body 300 needs to be covered on the container body 200 according to the unique specific direction, and the clearance structure can only function, and the cover body 300 is easy to put back and is troublesome.

As shown in fig. 2, the cover 300 has a left-right length greater than a front-rear width thereof, and the clearance structure has a left-right width less than a front-rear length thereof. Under the condition of ensuring that the avoiding structure is large enough, the left width and the right width of the avoiding structure are prevented from being too large, and the loss of the container capacity is reduced. The left and right sides described herein may correspond to the left and right sides with reference to fig. 3.

As shown in fig. 5, the cover body 300 is provided with an air hole 340, the air hole 340 is located outside the clearance structure, and the air hole 340 is located on the left and/or right of the clearance structure. Just contact when the culinary art, bleeder vent 340 still can have the condition of upwards running off steam, lift top 130 during the operation, if steam flows the easy scald hand in hand, avoid taking shelter from the empty structure and set up the left and right sides of taking shelter from the empty structure with bleeder vent 340, and operation position 132 is located the front end portion of top 130, when lifting top 130 operation like this, the hand just can not pass through bleeder vent 340 top, steam is difficult to flow to the hand, can avoid lifting top 130 like this, scald the hand from the steam that bleeder vent 340 flows.

As shown in fig. 2, the cover 300 is provided with a first magnetic member 322, in this embodiment, the first magnetic member 322 is specifically fixed on the steam connector 320; the top portion 130 is provided with a second magnetic member, and the first magnetic member 322 and the second magnetic member attract each other to seal the joint between the steam outlet 131 and the steam input port 310. Lid 300 and top 130 inhale the piece through magnetism and adsorb and connect for butt joint between them is inseparabler, avoids steam to flow from the gap between the two. One of the first magnetic member 322 and the second magnetic member is a magnet, and the other is a magnet or a member made of a material capable of attracting the magnet, for example, the first magnetic member 322 is a stainless steel sheet, and the second magnetic member is a magnet.

As shown in fig. 2-3 and 6-7, a handle 350 is provided on the cover 300, a locking structure is provided between the handle 350 and the container body 200, and the cover 300 is detachably fixed on the container body 200 through the locking structure. The handle 350 disposed on the cover 300 facilitates the user to grasp the steam connector 320 when opening the cover, thereby avoiding the possibility of scalding the user, and the cover 300 is locked on the container body 200 by the locking structure, thereby avoiding the cover 300 being taken out when lifting the top 130. Because the locking structure is arranged between the handle 350 and the container body 200, when the locking structure is unlocked, a hand is placed on the handle 350 for operation, when unlocking is completed, a user can lift the cover body 300 from the container body 200, and the operation is convenient.

The locking structure includes a locking portion 210 on the container body 200 and a locking groove 351 on the handle 350, and the locking portion 210 is inserted into the locking groove 351. The locking portion 210 and the locking groove 351 are simple in structure and stable in fit. Specifically, the locking portion 210 is a handle protruding from the sidewall of the container body 200. The protrusion of the locking portion 210 relative to the outer surface of the container body 200 can be used as a handle for holding the container body 200, and the structure has two functions, so that the overall structure of the container is simpler and the operation is more convenient. The edge of the cover body 300 is provided with a hinge part, the handle 350 is hinged on the hinge part, the handle 350 is provided with a mounting groove, the hinge part is positioned at the upper end part of the mounting groove, and a gap is formed between the hinge part and the bottom wall of the mounting groove to form the locking groove 351. Thus, the mounting groove and the groove are dual-purpose, the container structure is simplified, and the production cost is reduced.

In other alternative embodiments, the latch 210 may be located on the handle 350 and the latch groove 351 may be located on the container body 200; in addition, a rib for locking may be provided on the container body 200, and a locking hook may be provided on the handle 350, and the locking hook is hooked on the rib to lock the cover 300 and the container body 200.

As shown in fig. 7, the handle 350 is rotatably connected to the cover 300, and when the handle 350 is rotated to the upper limit position, the locking structure is unlocked, and the center of gravity of the handle 350 is located outside the rotation axis of the handle 350. After the cover body 300 is covered on the container body 200, the gravity center of the handle 350 is inevitably positioned at the outer side of the rotation axis, so that the handle 350 can rotate downwards around the axis under the action of the self gravity, the locking structure is naturally locked, the situation that a user forgets the locking operation is avoided, and the operation convenience is also improved.

As shown in fig. 7, the upper end of the handle 350 includes an inner arc surface 352 and an abutting surface 353, the abutting surface 353 is disposed to be biased to the outer side of the handle 350, and when the handle 350 rotates to the upper limit position, the abutting surface 353 of the handle 350 abuts against the side edge of the cover 300. Simple structure like this, spacing effectual, intrados 352 can avoid handle 350 to rotate the time and lid 300 lateral margin to take place to interfere, improves handle 350 pivoted smooth and easy nature. The abutting surface 353 abuts against the lateral edge of the column cover 300 to prevent the handle 350 from rotating further, and prevent the gravity center of the handle 350 from rotating to the inner side of the axis.

When the handle 350 is rotated to the upper limit position, the included angle between the handle 350 and the horizontal plane is less than or equal to 45 degrees, such as 30 degrees, 15 degrees and 10 degrees. Therefore, the user can hold the lower part of the handle 350 by hand, the upward force is convenient, and the natural falling of the handle 350 is also facilitated. In alternative embodiments, the handle 350 may be angled upward more than 45 degrees, such as 60 degrees, but so that the handle 350 is not easily held by hand and easily slides off the handle 350, the handle 350 may be angled downward more than 45 degrees, so long as it is ensured that the closure is unlocked.

As shown in fig. 6-7, when the handle 350 is pivoted to the upper limit position, the handle 350 is inclined upwardly from the inner end to the outer end. Therefore, the upper end of the handle 350 does not need to be too high to be higher than the top surface of the cover body 300, so that the upper end of the handle 350 is prevented from being too abrupt, and the locking structure can be ensured to be unlocked when the handle 350 is at the upper limit position. In other alternative embodiments, when the handle 350 is rotated to the upper limit position, the handle 350 may also be inclined downward from the inner end to the outer end; or, when the handle 350 rotates to the upper limit position, the handle 350 is horizontally arranged.
