detailed description

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The following is described by reference to the drawings The embodiments described are illustrative and are not intended to limit the invention.

A lid assembly 10 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

As shown in FIGS. 1 to 6, a lid assembly 10 according to an embodiment of the present invention includes a lid 100, a lid 120, a float 200, a knob slider 410, and a linkage slider 420.

The cover 120 is disposed inside the lid 100, wherein the inner and outer directions are for the cooking appliance having the lid assembly 10, in other words, the lid 120 is located on the lower side of the lid 100 when the lid assembly 10 is closed. The float 200 is movably mounted on the cover plate 120. The float 200 is provided with an exhaust passage 220. The two ends of the exhaust passage 220 extend to the two ends of the float 200 to form an intake port 210 and an exhaust port 230, respectively. The air inlet 210 is located at the lower end of the float 200 and the exhaust port 230 is located at the upper end of the float 200. The air inlet 210 is movable as the float 200 moves between an open position below the cover plate 120 and a closed position above the cover plate 120.

The knob slider 410 is rotatably mounted on the lid 100 between the lid opening position and the closing position, and the knob slider 410 is driven to rotate by a knob (not shown) on the lid 100. The linkage slider 420 is interlocked with the knob slider 410, and the linkage slider 420 presses the float 200 when the knob slider 410 is rotated from the closed position to the opening position to keep the air inlet 210 of the float 200 at In the open position, the linkage slider 420 releases the float 200 when the knob slider 410 is rotated from the open position to the closed position to allow the air inlet 210 to move with the float 200 when the float 200 is pressurized. Describe the closed position.

Specifically, the interlocking slider 420 is linearly movably mounted on the lid 100 between the pressing position and the releasing position and is interlocked with the knob slider 410. In other words, the rotational movement of the knob slider 410 can be converted into a linear motion of the linkage slider 420, wherein the linear motion trajectory of the linkage slider 420 can be restrained by providing a guide rib or the like in the lid 100.

When the lid is opened again after opening the lid during cooking and cooking, the knob slider 410 is turned to the opening position (as shown in FIGS. 1 and 2), and the knob slider 410 drives the linkage slider 420 to move to the position. In the pressing position, the linkage slider 420 presses the float 200, and the air inlet 210 moves down to the open position with the float 200, that is, under the cover plate 120, and the space inside the pot communicates with the external environment to reduce the hot air in the pot to push the float upward. The force of 200, in turn, reduces the friction between the linkage slider 420 and the float 200 during the screwing to facilitate the screwing of the closure, and the operation can be completed by simply rotating the knob slider 410 with one hand.

When the knob slider 410 is in the closing position (as shown in FIG. 5 and FIG. 6), the knob slider 410 drives the linkage slider 420 to move to the release position, and the linkage slider 420 does not generate a direction to the float 200. After the pressure is applied, the float 200 is lifted by the pressure in the pot, and the air inlet 210 is raised to the closed position, and the space inside the pot is blocked from the external environment to ensure airtightness in the closed state, and due to the float 200 When the pressure in the pot is raised, the interlocking slider 420 is stopped by the float 200 and cannot be moved to the pressing position, and the knob slider 410 cannot be turned to the opening position to realize the cover protection function.

The lid assembly 10 according to the embodiment of the present invention is provided with a float 200 that can move up and down, and the float 200 is provided with an air inlet 210 that can move up and down with the float 200, so that the air inlet 210 can be located at the cover Below 120 The open position moves between a closed position above the cover plate 120. Therefore, when the lid is opened again after the lid is opened during the cooking and cooking process, the air inlet 210 located in the open position can be utilized to sequentially pass the inner space of the pot through the air inlet 210, the exhaust passage 220, and the exhaust port 230 to the outside. The environment is connected, and the hot air in the pot is discharged through the curved arrow shown in Fig. 2, so that the pressure in the pot is close to the external environment pressure, which can greatly reduce the force of the hot gas in the pot to push the float 200 upward, thereby reducing the interference and facilitating the screwing. The cover not only makes the screwing more labor-saving and smooth, but also can be completed with one hand, the operation is simpler, and the cover protection function is realized at the same time. The lid assembly 10 according to the embodiment of the present invention has the advantages of convenient sealing in a hot state, simple operation, and the like.

It should be understood by those skilled in the art that the lid assembly 10 according to the embodiment of the present invention can also be provided with a zero pressure float 500, that is, the float 200 and the zero pressure float 500 are two different floats, and the zero pressure float 500 is used for detecting. The pressure in the pot is transmitted to signal the heating parameters.

A lid assembly 10 in accordance with an embodiment of the present invention is described below with reference to the drawings.

As shown in FIGS. 1 to 6, a lid assembly 10 according to an embodiment of the present invention includes a lid 100, a lid 120, and a float 200.

Specifically, as shown in FIGS. 2, 4, and 6, the exhaust passage 220 extends in the axial direction of the float 200, and the intake port 210 and the exhaust port 230 respectively extend in the radial direction of the float 200 and are adjacent to the float 200, respectively. Both ends. For example, the float 200 may be disposed to move up and down, and the exhaust passage 220 extends in the up and down direction. The intake port 210 is plural and disposed at the lower end of the float 200 at equal intervals along the circumferential direction of the float 200, and the exhaust port 230 is plural. Further, they are provided at the upper end of the float 200 at equal intervals along the circumferential direction of the float 200.

In some specific examples of the present invention, as shown in FIGS. 1 to 6, the knob slider 410 first enters an idle stroke when the cover position is rotated toward the closed position, in other words, the knob slider 410. The entire stroke of the block from the open position to the closed position includes an idle stroke, and the swing slider 410 first enters the idle stroke when rotating from the open position to the closed position. During the idle stroke, the interlocking slider 420 and the knob slider 410 are not interlocked, and the air inlet 210 of the float 200 is maintained in the open position.

Specifically, when the cover is opened during cooking and cooking, the knob slider 410 is located at the opening position (as shown in FIGS. 1 and 2), and the float 200 is pressed by the linkage slider 420, and the float 200 is advanced. The air port 210 is exposed from below the cover plate 120, and the space inside the pot communicates with the outside atmosphere to release the pressure in the pot to solve the problem of difficulty in closing the cover.

In this state, the rotary hand is rotated. Since the pressure in the pot is the same as the external environment pressure, the fasteners on the lid 100 (not shown) are not subjected to the pressure of the steam, that is, the fasteners are in the low position, and the teeth and the pot are pressed. A gap is left between the teeth (not shown), and the knob can be smoothly rotated. The knob slider 410 rotates from the opening position to the closing position by the rotation of the hand and first enters the idle stroke, that is, from FIG. 1 to FIG. 3, which shows the critical point of the idle stroke, that is, continues to rotate. Will turn out the empty trip. During the idle stroke, the rotation of the knob slider 410 does not interlock with the linkage slider 420, the linkage slider 420 always presses the float 200, and the air inlet 210 is always kept open (as shown in FIG. 4). Therefore, the pressure in the pot is always the same as the external environment pressure, and the knob is always in a flexible state of rotation. In this process, the fasteners and the teeth can be mutually The separated state is rotated to a state of being engaged with each other (the nip and the teeth of the nip state also have a gap in the height direction). When the rotation of the hand is continued, the knob slider 410 rotates out of the idle stroke, that is, from FIG. 3 to FIG. 5, in the process, the linkage slider 420 gradually removes the pressure on the float 200, and the float 200 is pressurized in the pot. Gradually, the air inlet 210 moves to the closed position (as shown in FIG. 6), and finally the space inside the pot is blocked from the external environment to complete the closing.

Thus, an idle stroke is designed in the stroke of the knob slider 410 from the open position to the closed position, in which the rotation of the rotary slider 410 and the linkage slider 420 are not linked, that is, the rotary hand The rotation of the slider 410 does not interlock with the float 200, and the air inlet 210 of the float 200 is maintained in the open position to ensure smooth rotation of the knob, and effectively solves the problem of the screwing in the pot after the hot state is closed. The problem. It can be understood that the stroke of the knob slider 410 from the closed position to the open position can also include an idle stroke or no idle stroke. The figure shows an example that does not include an idle stroke, ie The knob slider 410 is always interlocked with the float 200 during the transition from the closed position to the open position.

Optionally, the idle stroke accounts for 50%-80% of the entire rotational stroke of the knob slider 410 from the open position to the closed position. That is, the rotation angle of the knob slider 410 from the opening position to the closing position is β (as shown in FIG. 5), and the maximum rotation angle of the knob slider 410 in the idle stroke is α. (As shown in FIG. 3), wherein α/β=50%-80%, thereby controlling the timing of the float 200 to rise and fall by adjusting the rotation angle of the idle stroke, thereby controlling the timing of the exhaust, and ensuring smooth rotation.

In some embodiments of the present invention, as shown in FIG. 1 , FIG. 3 and FIG. 5 , the interlocking slider 420 is provided with spaced apart open cover driving ribs 421 and closing driving ribs 422 , and the rotating hand slider 410 is disposed There is an open cover transmission portion for pushing the cover driving rib 421 and a cover transmission portion 413 for urging the cover driving rib 422.

Optionally, the knob slider 410 is provided with a transmission slot 411. The cover transmission portion 412 is disposed on the inner wall surface of the transmission slot 411, and the cover transmission portion 413 is disposed on the outer wall surface of the knob slider 410, and the cover is opened. The driving rib 421 is located in the transmission groove 411, and the closing driving rib 422 is located outside the transmission groove 411. The transmission groove 411 is a closed-loop groove whose edge is closed and whose cross-sectional area is larger than the cross-sectional area of the opening cover rib 421, and the transmission groove 411 penetrates the knob slider in the thickness direction of the knob slider 410.

Wherein, when the knob slider 410 is in the opening position, the distance between the inner wall surface of the transmission slot 411 opposite to the opening cover transmission portion 412 and the opening cover transmission rib 421 is greater than or equal to the cover transmission portion 413 and the cover transmission. The distance between the parts 413.

Preferably, the opening cover transmission portion 412 is constituted by a part of the inner wall surface of the transmission groove 411, and the closing cover transmission portion 413 is constituted by a part of the outer wall surface of the knob slider 410.

Specifically, when the knob slider 410 is turned from the closed position to the open position (from FIG. 5 to FIG. 1), the open cover transmission portion 412 of the inner wall surface of the transmission groove 411 is pushed by the open cover transmission rib. 421 to push the linkage slider 420 to the position shown in FIG.

When the knob slider 410 is turned from the open cover position to the closed position and is located within the idle stroke (from FIG. 1 to 3), since the cross-sectional area of the transmission groove 411 is larger than the cross-sectional area of the opening cover rib 421, and the distance between the inner wall surface of the transmission groove 411 opposite to the opening cover transmission portion 412 and the opening cover transmission rib 421 is greater than or The distance between the cover transmission portion 413 and the cover transmission portion 413 is changed, and the transmission groove 411 moves relative to the cover opening rib 421, that is, the inner wall surface of the transmission groove 411 does not push the cover opening rib 421, and the knob slider 410 The outer wall surface does not push the cover driving rib 422, the linkage slider 420 and the knob slider 410 do not interlock, and the linkage slider 420 is stationary. When the knob slider 410 is turned from the opening position to the closing position and is outside the idle stroke (from FIG. 3 to FIG. 5), the closing transmission portion 413 of the outer wall surface of the knob slider 410 is pushed. The drive rib 422 is closed to push the linkage slider 420 to the position shown in FIG.

Therefore, it can be realized that the knob slider 410 and the linkage slider 420 are interlocked outside the idle stroke and do not interlock in the idle stroke, and the structure is simple and the transmission is stable. It can be understood here that the outer contour shape of the knob slider 410, the shape of the transmission groove 411, and the relative positions of the opening cover rib 421 and the cover transmission rib 422 can be set according to the requirements for the idle stroke in practical applications.

It will be understood by those skilled in the art that the knob slider 410 is rotated from the open state to the closed state (from FIG. 1 to FIG. 5), and passes through the state shown in FIG. The knob slider 410 is turned from the closed state to the open state (from FIG. 5 to FIG. 1) without going through the state shown in FIG.

In some embodiments of the present invention, as shown in FIG. 1 , FIG. 3 and FIG. 5 , the surface of the opening cover rib 421 facing the opening cover transmission portion 412 and the direction of the cover transmission rib 422 facing the cover transmission portion 413 The surface is a curved surface. For example, the cross-section of the open cover rib 421 is semi-circular, and the cross-section of the cover rib 422 is circular. Since the rotary slider 410 is linked with the linkage slider 420, The rotational motion of the knob slider 410 is converted into the linear motion of the interlocking slider 420, so that the contact portions of the two are rotated, and the friction can be reduced by providing the curved surface on the opening cover rib 421 and the cover driving rib 422. The force makes the movement of the knob slider 410 and the linkage slider 420 smoother, and the transmission is stable and the loss is small.

In some specific examples of the present invention, as shown in FIGS. 2, 4, and 6, the surface of the interlocking slider 420 facing the float 200 is provided with a guiding slope 423 and a pressing plane 424 connected to the guiding slope 423. The float 200 is gradually pressed down to the open position by the guide ramp 423 as the knob slider 410 is rotated from the closed position to the open position, and is finally pressed by the pressing plane 424.

Specifically, when the interlocking slider 420 is moved from the releasing position to the pressing position (moving from FIG. 6 to FIG. 2), the float 200 is gradually moved downward under the pressure of the guiding inclined surface 423, and the air inlet 210 reaches the open position and the float is floated. The 200 is pressed by the pressing plane 424 to maintain the air inlet 210 in the open position, preventing the float 200 from rising back without operating the knob slider 410.

Further, as shown in FIG. 2, FIG. 4 and FIG. 6, the lid 100 is provided with a float ram 240 that can move up and down and is located above the float 200, and the linkage slider 420 is covered by the knob slider 410. The float 200 is depressed by the float ram 240 as the position is rotated toward the open position to maintain the air inlet 210 of the float 200 in the open position. Pot cover assembly 10 further includes an elastic member 300 coupled to the float ram 240 and the lid 100, respectively, for providing an elastic stress that urges the float struts 240 upward. When the knob slider 410 is turned to the closing position, the linkage slider 420 is moved to the release position, the float ejector 240 is bounced by the elastic member 300, and the float ejector 240 is moved away from the float 200 and reserved with the float 200. For the space in which the float 200 rises, at this time, if the pressure is raised in the pot, the float 200 rises under the pressure in the pot, and the intake port 210 is closed.

Advantageously, as shown in FIG. 2, FIG. 4 and FIG. 6, the upper end of the float ejector 240 is provided with a stop cap 241, and the elastic member 300 is sleeved on the float ejector 240 and the two ends respectively abut against the lid 100 ( For example, the inner cover 110) and the spring on the stop cap 241 not only realize the reset function of the elastic member 300 to the float 200, but also can realize the mounting and positioning of the elastic member 300.

In some embodiments of the invention, as shown in Figures 2, 4 and 6, the lid 100 includes an outer lid (not shown) and an inner lid 110.

The inner cover 110 is disposed in the outer cover, and the knob slider 410, the linkage slider 420 and the elastic member 300 are disposed between the outer cover and the inner cover 110, and the two ends of the elastic member 300 and the inner cover 110 respectively It is connected to the float ejector 240. The cover 120 is disposed below the inner cover 110, and the float 200 is movably mounted on the cover 120.

Specifically, as shown in FIG. 2, FIG. 4 and FIG. 6, the cover plate 120 is provided with a float through hole 122 and a mounting seat 121 communicating with the float through hole 122. The float 200 is movably mounted on the mount 121. Up and through the float through hole 122, the float 200 can be movably mounted on the cover plate 120, and the movement track of the float 200 can be guided, thereby improving the stability of the movement of the float 200.
