Description

Pot support of gas-cooker, gas-cooker and callus on sole of pot support of gas-cooker

[ technical field ] A method for producing a semiconductor device

The invention relates to the field of gas cookers, in particular to a pot support of a gas cooker, a gas cooker with the pot support and a foot pad of the pot support of the gas cooker.

[ background of the invention ]

The pot support of the gas range is used to support a cooking appliance, and is generally made of a high temperature resistant metal due to its proximity to a fire source. The pot support is generally placed on a metal drip pan or directly on a panel made of metal, glass or ceramic. The pan support is affected by the deformation of the panel or the liquid containing plate or the manufacturing tolerance, and the pan support is difficult to avoid slight shaking after being placed on the liquid containing plate or the panel. In order to avoid shaking of the pan support and scratching of the panel by the pan support, most manufacturers install foot pads at the bottom of the pan support.

However, the foot pad is easy to fall off, and has become a common problem in the gas stove industry. For some foot pads which are more stable and are not easy to fall off, the foot pads have complex structures, the installation mode is relatively complicated, for example, the viscose-curing process is adopted, the installation time is long, the type of the applicable pot support is limited, and once the foot pads fall off, a user cannot install the foot pads.

Unless otherwise supported by sufficient evidence, the prior art described herein is not meant to be an admission that such prior art is widely known to those of ordinary skill in the art to which the invention pertains prior to the filing date of this application.

[ summary of the invention ]

An object of the present invention is to provide an improved pot support of a gas range, a gas range including the pot support, and a foot pad of the pot support of the gas range, in view of at least one of the above technical problems.

Another object of the present invention is to provide a pot support of a gas range, a gas range including the pot support, and a foot pad of the pot support of the gas range, which are not easily detached during use, in order to solve at least one of the above technical problems.

In order to achieve at least one of the above technical objects, the present invention proposes a technical solution such as the following embodiments: a pot support of a gas stove comprises a support body and a plurality of foot pads connected to the bottom of the support body, wherein in the use state of the pot support, a part of the support body playing a supporting role is placed on a supporting surface, wherein the part of the support body playing the supporting role comprises two grooves formed from different openings, and the extending directions of the two grooves are intersected; the foot pad comprises two embedded parts which are respectively matched with the two grooves, and the two embedded parts are mutually connected; in a use state of the pan support, each of the insertion portions is inserted into one of the grooves, and at least a part of the foot pad protrudes beyond the support body in a direction facing the support surface.

In the scheme, the two grooves are formed by opening different openings, the depth of each groove is not limited by the manufacturing process, and the depth of each groove can be made deeper, so that the foot pad is connected more firmly and is not easy to fall off. It is relatively easy for the footbed to manufacture inserts that fit deeper grooves, and the footbed is easily demolded.

The groove can be formed by milling or cutting, and the manufacturing process has no requirement on the width of the groove; the channel may also be formed in the body of the bracket by an integral molding process, such as stamping. Such manufacturing processes often require that the width of the channel be greater than the thickness of the stent body. The foot pad can be completely manufactured by an injection molding process.

Each groove and the embedding part matched with the groove mutually have acting force, and the extending directions of the two grooves are crossed, so that the acting force between the foot pad and the groove comprises a force in the horizontal direction and a force in the vertical direction or can be decomposed into a component force in the horizontal direction and a component force in the vertical direction. Thereby, on these two directions of level and vertical, all powerful effect is on the callus on the sole to act on respectively on two embedding parts of interconnect, so, two embedding parts are each other to be drawn back, thereby the connection of callus on the sole is more firm, is difficult for droing. Compared with the mode that the foot pad is connected through the groove formed by only one opening, the scheme of the invention has the obvious advantages of more firm connection and less possibility of falling off.

It should be explained that "the footpad includes two embedded parts respectively matched with the two grooves" means that the shape and the extending direction of the embedded parts are matched with the corresponding grooves. In particular, the thickness dimension of the insert part is slightly larger than the width of the groove, so that in the assembled state the insert part is at least partially in a compressed state. The extending direction of the embedded part is coincident with or approximately the same as the extending direction of the groove.

The expression "the two inserts are connected to one another" is to be understood to mean that the two inserts can be connected directly or indirectly.

By "each of the insert portions is inserted into one of the grooves" it is understood that the footpad is deformed such that each of the insert portions is inserted into one of the grooves, such that in an assembled state the insert portions are at least partially in a compressed or tensioned state. For example, the insert may be inserted into the groove with an interference fit, thereby creating a resilient compression between the surfaces of the insert to achieve a secure connection.

In one possible embodiment of the invention, the hardness of the foot pad is 60-70 HRB. It is verified that when the hardness is 60 to 70HRB, the foot pad can be easily installed without using a tool, and the foot pad is not easily detached, so that in an embodiment of the present invention, the foot pad can be manufactured by using rubber having a hardness within the above range. The hardness is above HRB70, and the foot pad is required to be installed by a tool. Where HRB refers to the B scale in Rockwell hardness measurement (HR).

In a possible embodiment of the present invention, a portion of the bracket body located between the two grooves is defined as a tongue portion, the tongue portion includes two corner portions adjacent to the two grooves, respectively, an angle formed by two edges enclosing the corner portions is defined as α, and a value of α is in a range of 0 ° < α ≦ 90 °, since the tongue portion has two corner portions, and the angle formed by the two edges enclosing the corner portions is an acute angle or a right angle, each corner portion plays a role in holding the foot pad portion covering the corner portion in an assembled state, that is, one corner portion plays a role in holding one embedded portion and the other corner portion also plays a role in holding the other embedded portion, so that the foot pad is held in two different directions, and since the two embedded portions are connected to each other, holding forces in two different directions are mutually restricted, and thus the foot pad is not easy to fall off.

It should be noted that "the angle formed by two edges enclosing said corner" is a measure of the amount by which one edge enclosing said corner must be rotated to overlap the other edge enclosing said corner.

In one possible implementation mode of the invention, the value range of α is more than or equal to α <90 degrees, and the value range is verified to be convenient for installation and not easy to fall off on one hand, and for the foot pad matched and connected with the groove, the angle range enables the foot pad manufactured by an injection molding process to be easier to demould.

In a possible embodiment of the invention, the foot pad has an open receiving cavity, and a portion of the bracket body located between the two grooves defines a tongue portion, and the tongue portion is received in the receiving cavity in the use state of the pan bracket. Thus, in the use state of the footbed, the footbed completely covers the tongue. The design can improve the strength of the foot pad, does not have a relatively weak part, and is not easy to break or damage in the using process. Meanwhile, the foot pad completely covers the tongue part, so that the foot pad can be ensured to exceed the bracket body in the direction facing the supporting surface, and the bracket body is prevented from directly contacting the supporting surface.

In a possible embodiment of the invention, the receiving space has a shape adapted to the tongue. Therefore, in an assembling state, the accommodating cavity is better matched with the tongue, and the tongue can play a better limiting role in the foot pad, so that the foot pad is not easy to separate from the support body.

In a possible embodiment of the invention, the foot pad comprises an inlet and a wall enclosing the receiving chamber, the two insert parts each adjoin the inlet and the insert part forms part of the wall. By the design, the whole foot pad forms a cavity structure, the structural strength is good, and the foot pad is not easy to break. When the foot pad is in use, the foot pad is sleeved on the tongue, namely, the foot pad is sleeved on the tongue after entering the groove, and the tongue limits the foot pad and is not easy to fall off.

In order to further improve the positioning effect on the foot pad, in a possible embodiment of the invention, the extending direction of the groove is a straight line, or the extending direction of the groove is a curve or a broken line, wherein an angle formed by the extending direction of the groove at the opening and the extending direction of the tail end of the groove is defined as β, and the value range of β is β or more than 90 degrees, so that the clamping effect on the foot pad is further increased, and the foot pad is less prone to falling off.

The "angle formed by the extending direction of the groove at the opening and the extending direction of the tail end of the groove" refers to a measure of the amount of rotation which is necessary when the extending direction of the groove at the opening and the extending direction of the tail end of the groove are overlapped.

In a possible embodiment of the invention, the supporting portion of the stent body is a structure extending straight, and/or the groove is formed at a corner of the stent body. The straight extending structure can facilitate the processing of the groove. And the groove is formed at the corner of the bracket body, and the corner structure of the bracket body has larger space, so that the foot pad is more convenient to mount.

In a possible embodiment of the invention, the bracket body comprises a frame and a plurality of support legs dispersedly connected to the frame, the supporting part of the bracket body is the frame, and the groove is arranged on the frame; alternatively, the supporting portion of the bracket body is the leg, and the groove is provided on the leg.

In one possible embodiment of the invention, the frame is rectangular or circular; when the frame is rectangular, the two grooves are formed on two adjacent sides of the frame, respectively. Not only can be convenient for processing the groove, but also is convenient for installing the foot pad.

In a possible embodiment of the invention, the shape of the foot pad is L-shaped, triangular or Christmas tree. The Christmas tree shape is in a shape of more than two layers (including two layers) of structures.

In order to further prevent the insertion portion from coming out of the corresponding groove, in one possible embodiment of the invention, the width of the groove increases inward along the extending direction of the groove.

Based on the technical purpose of the invention, the invention also provides the gas stove of the embodiment, which comprises the pot support of the gas stove of any one embodiment.

In addition, the present invention provides a foot pad of a pot holder for a gas range, for example, in an embodiment in which the pot holder includes a holder body, a supporting portion of the holder body is placed on one supporting surface, the supporting portion of the holder body includes two grooves opened from different openings, extending directions of the two grooves intersect, wherein the foot pad includes two insertion portions respectively fitted to the two grooves, and the two insertion portions are connected to each other; in a use state of the foot pad, each of the embedding portions is inserted into one of the grooves, and at least a part of the foot pad is beyond the bracket body in a direction facing the support surface.

In one possible embodiment of the invention, the foot pad has an open receiving space, the foot pad comprises an inlet and a wall enclosing the receiving space, the two insert parts each adjoin the inlet, and the insert parts form part of the wall.

In one possible embodiment of the invention, an angle formed by the embedded portion and a wall body adjacent to the embedded portion in a longitudinal section passing through the two embedded portions is defined as γ, and a range of γ is 0 ° < γ ≦ 90 °. Therefore, the foot pad is clamped with the edge of the groove in the use state by the structure, so that the foot pad is limited. And, two embedding parts all block with the slot card respectively from the equidirectional, two embedding parts are spacing each other, are drawn back each other. Thus, the connection of the footpad is firmer.

The term "angle between the insert and the wall adjacent to the insert" is understood to mean a measure of the amount of rotation of the wall adjacent to the insert when rotated to at least partially overlap the insert.

[ detailed description ] embodiments

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

First, please refer to fig. 1 to 7, wherein fig. 1 is a perspective view of a pot support according to a first embodiment of the present invention; FIG. 2 is an enlarged view of area B of FIG. 1; fig. 3 is a sectional view of a pot support according to a first embodiment of the present invention; FIG. 4 is an enlarged view of area C of FIG. 3; FIG. 5 is a schematic view of a stent body according to a first embodiment of the present invention; FIG. 6 is a perspective view of a footpad in accordance with a first embodiment of the present invention; fig. 7 is a cross-sectional view of a footpad in accordance with a first embodiment of the present invention.

The pot support 1 of the gas range of the present embodiment includes a support body 2 and a plurality of foot pads 300 connected to the bottom of the support body 2. Wherein, the bracket body 2 is made of metal material, and the foot pad 300 is made of rubber material.

Further, the stand body 2 includes a frame 10 and four legs 20 dispersedly connected to the frame 10. In the use state of the wok stand 1, the supporting parts of the stand body 2 are the feet 20. The four feet 20 rest on a support surface S in the use position of the pot support 1. Each leg 20 is of a straight extending configuration perpendicular to the support surface S. The support surface S may be the upper surface of the panel of the gas range or the surface of the liquid containing tray.

In this embodiment, the frame 10 is a circular frame, which can reflect part of the heat generated by the burner to the heating area, so as to reduce the heat loss of the combustion, and is called as a shaped pan support.

In the present embodiment, as shown in fig. 5, each leg 20 includes two grooves (groove 21 and groove 22) opened from different openings (opening 201 and opening 202), and the extending direction 21a of the groove 21 and the extending direction 22a of the groove 22 intersect. Two grooves on each leg 20 are formed at the corners of the legs 20. In this embodiment, the

grooves

21 and 22 on each leg are disposed on one of the outward facing corners of the legs 20.

Referring to fig. 4 and also to fig. 5, the

grooves

21 and 22 are arranged such that the legs 20 form a tongue-like structure. So here we define the part of the stent body 2 between the groove 21 and the groove 22 as the tongue 29. The tongue 29 includes two corner portions, i.e., a corner portion 291 and a corner portion 292, adjacent to the groove 21 and the groove 22, respectively.

In this embodiment, the two edges defining the corner 291 are the edge 293 and the edge 294, respectively, and the angle between the edge 293 and the edge 294 is designated as α, and α in this embodiment is 70 °.

The foot pad will be described in detail below. The footpad 300 includes two insertion portions, i.e., an insertion portion 310 and an insertion portion 320, which are respectively fitted into the

grooves

21 and 22. The insertion portion 310 and the insertion portion 320 are connected to each other. As shown in fig. 1 to 4, in the use state of the pan support 1, each insertion portion is inserted into one groove, i.e., the insertion portion 310 is inserted into the groove 21, the insertion portion 320 is inserted into the groove 22, and at least a part of the foot pad 300 protrudes beyond the support body 2 in a direction facing the support surface S. Referring to fig. 3 and 4, the wall 340 at the bottom of the foot pad 300 is a wall facing the supporting surface S when the pot support 1 is in use. Under the user state of pot support 1, wall body 340 is the edge that surpasss the stabilizer blade 20 bottom to callus on the sole 300 can play and prevent support body 2 fish tail panel, solves the problem that the pot support rocked because the panel warp.

In the use state of the pot rack 1, the floor mat 300 of the present embodiment does not go beyond the rack body 2 in the direction perpendicular to the supporting surface S, and, as shown in fig. 4, the floor mat 300 is flush with the edges of the legs 20 in the direction perpendicular to the supporting surface S.

In this embodiment, the foot pad 300 is made of rubber with a hardness of 60-70 HRB. As shown in Figs. 6 and 7, the footpad 300 of the present embodiment has an L-shaped, or boot-type, outer shape. The footpad 300 has an open receiving chamber 301. Specifically, the footpad 300 includes an inlet 300a and a wall 300b enclosing a receiving cavity 301. The insertion portion 310 and the insertion portion 320 are adjacent to the inlet 300a, respectively, and the insertion portion 310 and the insertion portion 320 constitute a part of the wall body 300 b.

Referring back to fig. 4, in the use state of the pot holder 1, the tongue portion 29 is accommodated in the accommodating cavity 301. As can be seen from fig. 4, the receiving space 301 has a shape adapted to the tongue 29. Specifically, as shown in fig. 7, on a longitudinal section passing through the insertion portion 310 and the insertion portion 320, adjacent to the insertion portion 310 is a wall body 330, an angle formed by the insertion portion 310 and the wall body 330 is denoted by γ 1, and γ 1 in this embodiment is 70 °. Adjacent to the insert 320 is a wall 340, and the angle formed by the insert 320 and the wall 340 is denoted by γ 2, where γ 2 is 60 ° in this embodiment.

As shown in fig. 4, in the use state of the pot support 1, the corner 291 acts as a limit for the foot pad, so that the corner 291 exerts a force F1 on the foot pad 300, which force F1 can be decomposed into a component in the x-direction and a component in the z-direction. The corner 292 also serves as a limit for the foot pad, and the corner 292 provides a force F2 for the foot pad 300, which F2 can also be decomposed into a component in the x-direction and a component in the z-direction. Wherein the x-direction can be regarded as a direction horizontally towards the interior of the pot support and the z-direction can be regarded as a direction opposite to the direction of gravity.

Therefore, when the foot pad 300 is to be detached from the bracket body 2, the embedded portion 310 is to be moved downward (i.e., toward the opposite direction of the z direction) against at least the component force F1 in the z direction; the embedded portion 320 is moved at least to the right (i.e., in the opposite direction to the x-direction) against the component force of the force F2 in the x-direction. Because the inlay 310 is interconnected to the inlay 320, the footpad 300 is a unitary structure, and downward movement of the inlay 310 is also subject to resistance from the inlay 320, i.e., the inlay 310 is also subject to a force component in the z-direction of F2. Through the above force analysis, it can be seen that the insertion portion 310 is difficult to be separated from the groove 21 in the use state of the pot holder. Likewise, the rightward movement of the embedded portion 320 is also affected by the resistance from the embedded portion 310, i.e., the embedded portion 320 is also affected by the component force of F1 in the x direction. Therefore, the insertion part 320 is hardly separated from the groove 22 even in the use state of the pot holder. In conclusion, once the foot pad is installed in place, the foot pad is not easy to fall off from the bracket body.

Further, as shown in fig. 4 and 5, the groove 21 extends linearly, and the width increases inward in the extending direction 21a of the groove 21. The grooves 22 also extend linearly, and the width of the grooves 22 increases inward along the extending direction 22a of the grooves 22. The advantage of this design is, the width of slot is big or small inside, and for the embedding part of inserting into the slot through the deformation, the deeper the slot the position corresponds the size of embedding part bigger, and the embedding part is more difficult to break away from corresponding slot after the installation.

Referring to fig. 8 and 9 again, wherein fig. 8 is a partial schematic view of a stent body according to a second embodiment of the invention; fig. 9 is a partial schematic view of a pan support according to a second embodiment of the invention. The same or similar structures in the second embodiment as in the first embodiment are labeled with the same or similar labels, and the functions and actions thereof are the same or similar, and are not repeated herein. The present embodiment is different from the first embodiment in that the specific shapes of the

grooves

23 and 24 are different from those of the

grooves

21 and 22. The

trenches

23 and 24 are trenches extending substantially at the same width. As mentioned above, the width of the

grooves

21 and 22 increases inward along the extending direction of the grooves.

Further, in the use state of the pot holder 1, the foot pad 400 of the present embodiment protrudes beyond the holder body 2 in a direction perpendicular to the supporting surface S, and as shown in fig. 9, the foot pad 400 protrudes beyond the edge of the leg 20 in a direction perpendicular to the supporting surface S.

The tongue 29 likewise comprises two

corner portions

291 and 292, the two edges surrounding the corner portion 291 being at an angle α, in this embodiment α being 80 °, the two edges surrounding the corner portion 292 also being at an angle 80 °, also indicated as α in fig. 7.

The stand body of the present embodiment includes a frame 10 and a plurality of legs 20 dispersedly coupled to the frame 10. The frame 10 is a flat extending frame and is a part of the bracket body for supporting. In the use state of the pot support, the frame 10 is placed on the support surface S.

The frame 10 is a rectangular frame comprising four sides, indicated in turn by

reference numerals

10a, 10b, 10c, 10 d. One foot pad 500 is installed at the intersection of every two adjacent sides, in other words, each foot pad 50 is installed at the corner of the frame 10.

The frame 10 comprises two grooves, namely a groove 11 and a groove 12, opening from different openings. Taking region D in fig. 11 as an example, the groove 11 is formed on the side 10D of the frame 10, and the opening of the groove 12 is formed on the side 10 a.

The

grooves

11 and 12 extend in an L-shaped broken line, wherein the angle between the direction of the groove 11 at the opening and the direction of the groove 11 at the end is indicated at β, in this embodiment β is 90 °, the angle between the direction of the groove 12 at the opening and the direction of the groove 12 at the end is also 90 °, also indicated at β in fig. 13.

The portion of the frame 10 between the

grooves

11 and 12 is defined as a tongue 19, the tongue 19 comprising a corner 191 and a corner 192, wherein the corner 191 is adjacent to the groove 11 and the corner 192 is adjacent to the groove 12, the angle between the two edges bounding the corner 191 is 90 °, α in fig. 12, the angle between the two edges bounding the corner 192 is also 90 °, α in fig. 12.

As shown in fig. 14, the foot pad 500 is shaped like a Christmas tree, and referring again to fig. 15, the foot pad 500 has an open receiving chamber 501. Foot pad 500 includes an inlet 500a and a wall 500b enclosing a receiving cavity 501. The insertion portion 510 and the insertion portion 520 are adjacent to the inlet 500a, respectively, and the insertion portion 510 and the insertion portion 520 constitute a part of the wall body 500 b.

As shown in fig. 15, the

insert portions

510 and 520 are L-shaped in a longitudinal section of the footpad passing through the

insert portions

510 and 520. In the longitudinal section, adjacent to the insertion portion 510 is a wall 530, adjacent to the insertion portion 520 is a wall 540, an angle formed by the insertion portion 510 and the wall 530 is 90 °, and an angle formed by the insertion portion 520 and the wall 540 is also 90 °. For ease of assembly, the intersection of insert 510 and wall 530 is rounded, as is the intersection of insert 520 and wall 540.

In the use state of the pot holder, the L-shaped embedding part 510 is inserted into the L-shaped groove 11, the L-shaped embedding part 520 is inserted into the L-shaped groove 12, and the tongue 19 is accommodated in the accommodating cavity 501. Wherein the receiving cavity 501 has a shape adapted to the tongue 19. Also, the foot pad 500 is beyond the bottom of the frame 10 in a direction facing the support surface S.

Due to the formation of the groove 11, a protrusion 15 is formed on the frame 10 adjacent to the groove 11, and likewise, a protrusion 16 is formed on the frame 10 adjacent to the groove 12. Taking fig. 12 as an example, in the use state of the pot holder, the embedded portion 510 is blocked by the protrusion 15, and in order to fall off the embedded portion 510 from the groove 11, at least the force in the y direction acting on the embedded portion 510 by the protrusion 15 and the force in the x direction acting on the embedded portion 510 by the tongue 19 need to be overcome. That is, the embedding portion 510 receives at least forces from directions parallel to the x-direction and the y-direction on the supporting surface S, which intersect and are perpendicular to each other. At least to overcome these two forces, the insert 510 may be disengaged from the groove 11, which is a small probability event in normal use of the pot support.

Similarly, the insert portion 520 is blocked by the protrusion 16, and the insert portion 520 is required to be removed from the groove 12 at least against the force in the x direction applied to the insert portion 520 by the protrusion 16 and the force in the y direction applied to the insert portion 520 by the tongue portion 19. That is, the insert portion 520 is also subjected to forces from the x-direction and the y-direction, and the insert portion 520 is removed from the groove only by overcoming at least the above forces. Therefore, the insertion part 520 is very difficult to be separated from the groove 12 in the use state of the pot holder.

The above are only three embodiments of the invention, however, many more embodiments of the invention can be derived by modifying and combining them.

For example, the

grooves

21 and 22 in the first embodiment may be provided on the frame 10 shown in fig. 10, and the footpad 300 in the first embodiment may be correspondingly mounted on the frame shown in fig. 10. Similarly, the two

grooves

23 and 24 of the second embodiment may be formed on the frame 10 shown in FIG. 10, and the footpad 400 of the second embodiment may be correspondingly mounted on the frame shown in FIG. 10. While the two

grooves

11 and 12 of the third embodiment can also be provided on the legs 20 shown in the first or second embodiment, the foot pad 500 of the third embodiment can correspondingly also be mounted on the legs 20 shown in the first or second embodiment.

Since the illustrated embodiments are limited, some embodiments will be described using a summary language, for example, the angle formed by two edges surrounding a corner is defined as α within a range of 0 ° < α ° or less than 90 °, so that the foot pad can be well prevented from falling off, in practical applications, α is preferably within a range of 60 ° < α <90 °, so that not only the foot pad can be well prevented from falling off, but also the groove can be conveniently processed.

For another example, when the extending direction of the groove is a curved line or a broken line, the angle formed by the extending direction of the groove at the opening and the extending direction of the end of the groove is defined as β, and the value range can be β ≥ 90 °.

Also, for example, in a longitudinal section passing through the two insertion portions, an angle formed by the insertion portion and a wall body adjacent to the insertion portion is defined as γ, and a value of γ may be in a range of 0 ° < γ ≦ 90 °.

The various embodiments of the individual components described in connection with fig. 1 to 15 may be combined with each other in any given way to achieve the advantages of the invention.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
