Description

Technical Field

[0001] The invention relates to the technical field of household kitchenware, and in particular to a gas stove which can be lifted and lowered. Background Art

[0002] The gas stoves currently in use can be divided into tabletop gas stoves and embedded gas stoves. The tabletop gas stove can only be placed on the cabinet, and the overall decoration effect is poor. It is easy to scale and accumulate liquid under the tabletop gas stove; the embedded gas stove has a good overall decoration effect, and the stove can be embedded in the cabinet through the chassis. This traditional embedded gas stove, no matter what style, needs to have a panel that can cover the top of the chassis and be inverted on the cabinet countertop, which not only affects the overall appearance of the cabinet, but also easily produces many sanitary dead corners. In addition, if a relatively inferior panel is used, it is also easy to increase safety hazards such as panel explosion. For this reason, the prior art provides a Chinese utility model patent "A Lifting Gas Stove" with patent number ZL201921408244.8 (authorization announcement number CN210511787U), which uses a lifting device to drive the burner up and down, so that the stove has a good planarization effect, but the gas stove only realizes the lifting of the burner burner head, and the pot bracket is still arranged on the stove panel, and the synchronous lifting of the pot bracket and the burner burner head cannot be realized, so further improvements are needed. Summary of the invention

[0003] The first technical problem to be solved by the present invention is to provide a gas stove in which a pot support and a burner head can be raised and lowered synchronously in view of the above-mentioned existing technical status.

[0004] The second technical problem to be solved by the present invention is to provide a gas stove capable of ensuring that the pot support and the burner head are balanced when they are raised or lowered in view of the above-mentioned existing technical status.

[0005] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is as follows: the gas stove comprises a bottom shell having a storage space therein and an open top, and a panel covering the top of the bottom shell, characterized in that the panel is provided with a central hole and peripheral holes located outside the central hole, and further comprises:

[0006] a burner, disposed on the first support plate, arranged in the accommodation space and below the central hole of the panel;

[0007] A pot support, disposed on a second support plate below the first support plate, comprising at least two pot legs connected to the second support plate and located below the peripheral hole; and

[0008] The driving mechanism comprises a driving source and a first connecting rod mechanism and a second connecting rod mechanism respectively connected to the first supporting plate and the second supporting plate to drive the burner and the pot support to move up and down synchronously relative to the panel.

When cooking is not needed, the burner and the pot support move downward synchronously, so as to be flush with the panel to realize the flatness of the panel; when cooking is needed, the burner and the pot support move upward synchronously, and one is fast and the other is slow, that is, the movement speed of the pot support is faster, so that after rising to the right position, the pot support is higher than the burner by a stable distance to form the space required for combustion.

[0013] In order to realize the synchronous rising movement of the burner and the pot support, and one is fast and the other is slow, from the perspective of structural simplicity, preferably, the first connecting seat includes a connecting seat portion that can slide along the guide rail and a connecting portion with a "U"-shaped cross-section, the connecting portion includes a transverse portion connected to the connecting portion and a first vertical portion and a second vertical portion arranged on both sides of the transverse portion, the first vertical portion and the second vertical portion are respectively provided with a first pin shaft hole and a second pin shaft hole that are staggered, the first pin shaft hole is closer to the first plate body or the second plate body than the second pin shaft hole, the first lower end of the first connecting rod is connected to the second pin shaft hole, and the third lower end of the third connecting rod is connected to the first pin shaft hole.

[0014] In order to achieve the first plate body and the second plate body approaching and moving away from each other, preferably, the driving source of the driving mechanism includes a motor and a screw connected to the driving end of the motor, the screw is penetrated by the first plate body and the second plate body, and the threads on the screw corresponding to the movement range of the first plate body and the second plate body are oppositely arranged.

Since the burner and the pot support are lifted and lowered in the vertical direction relative to the bottom shell, only by ensuring the symmetry of the two ends of the first support plate and the second support plate during the lifting process can the absolute level of the first support plate and the second support plate be ensured, otherwise the movement of the mechanism is likely to cause poor movement, noise or even jamming, for this reason, the indexing adjustment parts are provided with at least two first adjustment holes at intervals in the circumferential direction, and correspondingly, the first plate and the second plate are respectively provided with second adjustment holes, and the connecting parts are fastened between the first adjustment holes and the corresponding second adjustment holes, so that the first plate and the second plate are always kept in a balanced state.

[0016] Furthermore, the outer periphery of the adjusting disk is larger than the outer periphery of the screw rod, and the first adjusting hole of the disk is divided into 4 to 8 circumferentially, and correspondingly, the second adjusting hole is also divided into 4 to 8 circumferentially.

[0017] In order to ensure that the second support plate maintains low noise during movement, preferably, the driving source of the driving mechanism is restricted to a driving source bracket with a "U"-shaped cross-section, and the two vertical arms of the driving source bracket extend horizontally to have horizontal portions, and elastic parts are arranged on the horizontal portions and the second support plate.

[0018] Compared with the prior art, the advantages of the present invention are that the burner and the pot support move up and down synchronously regardless of whether they are in the cooking state or the non-cooking state. In the non-cooking state, the burner and the pot support move down synchronously, and the tops of the burner and the pot support are flush with the central hole and the peripheral hole respectively, so that the gas stove panel is in a purely flat state, forming a flat surface for placing objects while having dust-proof and beautiful effects. In the cooking state, the burner and the pot support move up in a direction away from the bottom shell to support the pot, and after rising into place, the pot support is higher than the burner by a stable distance to form a space required for combustion.

[0026] The present invention is further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 The best embodiment of the present invention is shown in FIG. 1 . The gas stove of this embodiment includes a bottom shell 1, which has a storage space and an open top, and a panel 2 covering the top of the bottom shell 1, the panel 2 is provided with a central hole 21 and a peripheral hole 22 located outside the central hole 21, and also includes a burner 3 arranged on a first support plate 31, the burner 3 is arranged in the storage space and is located below the central hole 21 of the panel 2, and a pot support 4 is arranged on a second support plate 41 located below the first support plate 31, including at least two pot legs 42 connected to the second support plate 41 and located below the peripheral hole 22; and a driving mechanism 5 for driving the burner 3 and the pot support 4 to move up and down synchronously relative to the panel 2, the driving mechanism 5 includes a driving source 50 and a plurality of pot legs 42 connected to the second support plate 41 and located below the peripheral hole 22. With the first connecting rod mechanism 51 and the second connecting rod mechanism 52 on the first supporting plate 31 and the second supporting plate 41, the burner 3 and the pot support 4 can be synchronously moved up and down under the driving action of the driving mechanism 5 whether in the cooking state or the non-cooking state. In the non-cooking state, the burner 3 and the pot support 4 are synchronously moved down, and the tops of the burner 3 and the pot support 4 are flush with the central hole 21 and the peripheral hole 22 respectively, so that the gas stove panel 2 is in a purely flat state, forming a flat surface for placing objects while having dust-proof and beautiful effects. In the cooking state, the burner 3 and the pot support 4 move up in a direction away from the bottom shell 1 to support the pot, and after rising into place, the pot support 4 is higher than the burner 3 by a stable distance to form a space required for combustion.

[0028] Specifically, the driving mechanism 5 of this embodiment also includes a first plate body 53 and a second plate body 54 which are arranged on the bottom shell 1 and can be relatively close to and away from each other, a first connecting seat 55 connected to the first plate body 53 and the second plate body 54, and a guide rail 56 for the first connecting seat 55 to slide relative to it. Correspondingly, a second connecting seat 11 for connecting the first connecting rod mechanism 51 and the second connecting rod mechanism 52 is also provided on the bottom shell 1. The first connecting fulcrums of the first connecting rod mechanism 51 and the second connecting rod mechanism 52 are connected to the second connecting seat 11 through their respective corresponding first pin shafts 57, and the second connecting fulcrums of the first connecting rod mechanism 51 and the second connecting rod mechanism 52 are connected to the first connecting seat 55 through their respective corresponding second pin shafts 58, and the third connecting fulcrums of the first connecting rod mechanism 51 and the second connecting rod mechanism 52 are connected to their respective corresponding support plates. The first connecting rod mechanism 51 and the second connecting rod mechanism 52 connected by the first plate body 53 and the second plate body make it possible for the burner 3 and the pot support leg 42 to move upward synchronously when the first plate body 53 and the second plate body are approached to each other; and the first connecting rod mechanism 51 and the second connecting rod mechanism 52 connected by the first plate body 53 and the second plate body make it possible for the burner 3 and the pot support leg 42 to move downward synchronously when the first plate body 53 and the second plate body are moved away from each other. In addition, in order to realize the rising speed of the pot support 4 and the burner 3, one is fast and the other is slow, from the perspective of simple structure, the second connection fulcrums of the first link mechanism 51 and the second link mechanism 52 are connected to the first connection seat 55 through the second pin shaft 58 respectively, wherein the second connection fulcrums of the first link mechanism 51 and the second link mechanism 52 are staggered, and the second connection fulcrum of the second link mechanism 52 is farther away from the first plate body 53 or the second plate body 54 than the first connection fulcrum of the first link mechanism 51, so as to realize: when the burner 3 and the pot support 4 move upward synchronously relative to the panel 2, the pot support 4 moves upward by a greater distance than the burner 3 to form the space required for combustion. When cooking is not needed, the burner 3 and the pot support 4 move downward synchronously, so as to be flush with the panel 2 to realize the flatness of the panel 2; when cooking is needed, the burner 3 and the pot support 4 move upward synchronously, and one is fast and the other is slow, that is, the moving speed of the pot support 4 is faster, so that after rising to the right position, the pot support 4 is higher than the burner 3 by a stable distance to form the space required for combustion.

[0029] Among them, the way in which the first connecting rod mechanism 51 is connected to the first connecting seat 55 and the second connecting seat 11, from the perspective of structural simplicity, the first connecting rod mechanism 51 includes a first connecting rod 511 and a second connecting rod 512, the second upper end 5121 of the second connecting rod 512 is connected to the middle part of the first connecting rod 511, the second lower end 5122 of the second connecting rod 512 is connected to the second connecting seat 11 as a first connecting fulcrum, and the first lower end 5111 of the first connecting rod 511 is connected to the first connecting seat 55 as a second connecting fulcrum, and the first upper end 5112 of the first connecting rod 511 is connected to the first support plate 31. Similarly, from the perspective of structural simplicity, the way in which the first connecting rod mechanism 51 is connected to the first connecting seat 55 and the second connecting seat 11, the second connecting rod mechanism 52 includes a third connecting rod 521 and a fourth connecting rod 522, the fourth upper end 5221 of the fourth connecting rod 522 is connected to the middle part of the third connecting rod 521, the fourth lower end 5222 of the fourth connecting rod 522 is connected to the second connecting seat 11 as a first connecting fulcrum, and the third lower end 5211 of the third connecting rod 521 is connected to the first connecting seat 55 as a second connecting fulcrum, and the third upper end 5212 of the third connecting rod 521 is connected to the second support plate 41. In order to realize the synchronous rising movement of the burner 3 and the pot support, one fast and the other slow, the first connecting seat 55 is adaptively improved in structure, including a connecting seat portion 551 that can slide along the guide rail 56 and a connecting portion 552 with a "U"-shaped cross-section, the connecting portion 552 includes a transverse portion 5521 connected to the connecting portion 552 and a first vertical portion 5522 and a second vertical portion 5523 arranged on both sides of the transverse portion 5521, the first vertical portion 5522 and the second vertical portion 5523 are respectively provided with a first pin shaft hole 5520 and a second pin shaft hole 5530 that are staggered, the first pin shaft hole 5520 is closer to the first plate body 53 or the second plate body 54 than the second pin shaft hole 5530, the first lower end 5111 of the first connecting rod 511 is connected to the second pin shaft hole 5530, and the third lower end 5211 of the third connecting rod 521 is connected to the first pin shaft hole 5520. Finally, in order to achieve the mutual approach and distance between the first plate body 53 and the second plate body 54, preferably, the driving source 50 of the driving mechanism 5 includes a motor 501 and a screw 502 connected to the driving end of the motor 501, and the screw 502 is penetrated through the first plate body 53 and the second plate body 54, and the threads on the screw 502 corresponding to the movement range of the first plate body 53 and the second plate body 54 are oppositely arranged.In addition, since the burner 3 and the pot support 4 are lifted and lowered in the vertical direction relative to the bottom shell 1, only by ensuring the symmetry of the two ends of the first support plate 31 and the second support plate 41 during the lifting process can the absolute levelness of the first support plate 31 and the second support plate 41 be guaranteed. Otherwise, it is very likely to cause poor movement, noise or even jamming during the movement of the mechanism. For this reason, the first plate body 53 and the second plate body 54 are respectively provided with indexing adjustment members 6 at the positions corresponding to the screw rods, and the indexing adjustment member 6 includes an adjustment disk 61 connected to the screw rod 502, and the adjustment disk 61 is circumferentially spaced with at least two first adjustment holes 611. Correspondingly, the first plate body 53 and the second plate body 54 are respectively provided with second adjustment holes 500 adapted to the first adjustment holes 611, and the first plate body 53 and the second plate body 54 are provided with connecting members 5000 connecting the first adjustment hole 611 and the second adjustment hole 500. At least two first adjustment holes 611 are arranged at intervals in the circumferential direction on the indexing adjustment member 6. Correspondingly, the first plate 53 and the second plate 51 are respectively provided with corresponding second adjustment holes 500. The first plate 53 and the second plate 54 are always kept in a balanced state by fastening between the first adjustment hole 611 and the corresponding second adjustment hole 500 through the connecting member 5000. The outer periphery of the adjusting disk 61 is larger than the outer periphery of the screw rod. The first adjustment holes 611 of the disk 61 are divided into 4 to 8 in the circumferential direction. Correspondingly, the second adjustment holes 500 are also divided into 4 to 8 in the circumferential direction. The adjusting disk on the indexing adjustment member 6 is divided into 6 equal parts along the circumference of its disk, or divided into four equal parts or eight equal parts, so that the continuous adjustment accuracy of the threaded hole between the nut and the indexing adjustment member 6 is 1 / 6P (P is the screw pitch. If the first adjustment hole on the indexing adjustment member is divided into eight equal parts, the adjustment accuracy is 1 / 8 pitch. The higher the division, the higher the adjustment accuracy). The graduation adjustment member 6 needs to be adjusted accordingly before the burner 3 and the pot support 4 rise or move down. In addition, in order to ensure that the second support plate 41 maintains low noise during movement, the driving source 50 of the driving mechanism is restricted to a driving source support 510 with a "U"-shaped cross-section. The two vertical arms of the driving source support 510 extend horizontally to have horizontal portions, and elastic members 5200 are provided between the horizontal portions and the second support plate 41.

[0030] In summary, the use process of the gas stove is as follows: the first lower end 5111 of the first connecting rod 511 in the first connecting rod mechanism 51 is used as the second connecting fulcrum and is marked as b, the third connecting fulcrum of the first upper end 5112 of the first connecting rod 511 is marked as d, and the second upper end 5121 of the second connecting rod 512 is connected to the middle part of the first connecting rod 511, and the connection point is marked as f; correspondingly, the third lower end 5211 of the third connecting rod 521 in the second connecting rod mechanism 52 is used as the second connecting fulcrum and is marked as a, the third connecting fulcrum of the third upper end 5212 of the third connecting rod 521 is marked as c, and the fourth upper end 5221 of the fourth connecting rod 522 is connected to the middle part of the third connecting rod 521, and the connection point is marked as e;

[0031] The effect of such arrangement is that when points a and b move on the horizontal axis (i.e., the first connecting seat 55 moves relative to the guide rail 56), points c and d must move on the vertical axis, that is, the longitudinal axis direction does not need the guide rail 56 to ensure that the movement trajectory of points c and d must be on the vertical axis. This structure can well ensure the stability of the rising trajectory of the burner 3 and the pot support 4.

[0032] Figure 4 is the starting state, Figure 5 After the movement, when points a and b move the same distance, points c and d move different distances, thus forming a height difference; Figure 2 As shown in , when a and b move 32.56mm to the right at the same time, c moves up 42mm, d moves up 22mm, and c and d form a height difference of 20mm. This structure can well meet the following requirements: when the gas stove is folded, the pot support 4 and the burner 3 are lowered to be flush with the panel 2 to achieve a flat panel 2; when rising, the burner 3 and the pot support 4 move at the same time, one fast and the other slow, and the pot support 4 moves faster, so that after rising to the right position, the pot support 4 is higher than the burner 3 by a stable distance to form the space required for combustion.
