Description

  The present invention relates to a tabletop stove equipped with an operation knob.

Conventionally, a tabletop stove used on a table or the like is known. For example, as shown in FIGS. 1 and 2, the cassette stove disclosed in Patent Document 1 uses the fuel gas in the gas cylinder 5 as a heat source, and can be used by being transported to a desktop.
That is, the fuel gas from the gas cylinder 5 is supplied to the gas burner through a flow rate control valve that controls the degree of opening and closing of the gas passage and the governor 4 that is a pressure regulator. An instrument plug knob (operation knob) 14 is connected to the flow rate control valve via an operation shaft, and the gas flow supplied to the gas burner is controlled by rotating the instrument plug knob 14.

JP 2013-76524 A

  By the way, as for the cassette stove placed on the table, the instrument stopper 14 is often arranged on the side surface. For this reason, for example, when picking the instrument plug knob 14 with a finger, since the distance between the table and the instrument plug knob 14 is short, the user may pinch the center of the instrument plug knob 14 and rotate it. In this case, although depending on the power of the user, it is difficult to turn the instrument stopper 14 and it may be difficult to perform a delicate heating and reducing operation. The difficulty of turning such a knob is not limited to a cassette cooker that uses gas as a heat source, but can also be placed on a tabletop, and the same applies to an electric cooker that has an operation knob on the side. .

  In this respect, in order to make the instrument stopper knob 14 easy to turn, the torque characteristic may be reduced. However, in the case of a stove, if the torque characteristic is reduced, when the object or human body hits the instrument stopper 14, the instrument stopper 14 is easily turned around, causing unexpected fire control or stopping. There is also a risk that the stove that should have been heated.

  The present invention has been made in view of the above, and provides a tabletop stove that realizes an operation knob that is easy to turn without changing the torque characteristics of the instrument itself, and that can easily perform a heating operation. For the purpose.

  According to the present invention, the above-described problem is a housing that houses a heat source controller that controls the supply amount of the heat source, and is disposed on a lateral surface of the housing and connected to the heat source controller. A tabletop stove comprising an operation knob adapted to operate the supply amount by rotating, wherein the operation knob protrudes from a lateral surface of the housing and is picked by a finger to perform the operation. The both ends of the knob body formed by extending so as to be spaced apart from the central area, compared to the central area in the axial direction of the rotation, This is solved by a desktop stove with a large protruding dimension.

  According to the above configuration, the knob body that is picked up by the finger and rotated is compared to the central area in the direction of the rotation axis, and is formed at both end portions that are formed to extend away from the central area. However, the protruding dimension is larger. Therefore, it becomes easier for the user to put his / her fingers toward both ends protruding from the central region in the direction of the rotation axis. In other words, the central region in the direction of the rotation axis has a smaller degree of protrusion than both ends, and thus serves as a guiding means for guiding the finger to both ends. Therefore, since the user operates by placing fingers at both ends, the distance from the rotation shaft increases, and the knob body can be easily turned without changing the torque characteristics of the instrument itself.

Preferably, the width of the both end portions increases as the distance from the central region increases.
If it does so, the side surface of both ends will become an inclined surface, and when turning a knob main body, a finger | toe will be easily caught on this inclined surface. Therefore, the force for picking both ends may be weakened, and the picking main body can be easily turned accordingly.

Preferably, a virtues for placing pans are arranged on the casing, and the placing surface for placing the pans of the virtues is formed at a central portion in the longitudinal direction. The width is the largest, and the width becomes narrower from the central portion toward the tip and the base.
Therefore, it is possible to guide the user to select a pot having a preferable size according to the desktop stove used. That is, if small pots are placed only on the tip of the virtues, the pots may fall from the virtues at any moment. On the other hand, when a large pot that exceeds the root is placed on the virtues, the pot becomes unstable, and if the tabletop stove is a cassette stove, the heat of the pot may adversely affect the gas cylinder. is there. For this reason, there is a preferred size for pans placed on a desktop stove. Therefore, the use of pots of this preferred size is visually induced by maximizing the central portion in the longitudinal direction with respect to the width of the mounting surface of Gotoku.

  Preferably, the casing includes a cylinder accommodating portion having a gas cylinder accommodating space and an openable / closable lid that covers the accommodating space, and is adjacent to the cylinder accommodating portion on the casing. And a gas burner for receiving gas from the gas cylinder, and a removable top plate having through holes formed so as to expose the ignition electrodes, and the top plate is rounded at all four corners in plan view. The through hole has a burner hole that exposes the gas burner and an electrode hole that is connected to the burner hole and exposes the electrode. The electrode hole is used for the burner. It is formed in two places opposite to each other of the holes, and the lid body has a protruding portion that protrudes so as to be adjacent to the rounded portion of the top plate when closed. .

Then, since the four corners of the top plate are rounded in plan view, the area of the four corners becomes small, making it difficult for objects and human bodies to hit, and even if it hits it, it is difficult to catch it. Can be prevented.
Moreover, about the through-hole of the top plate which exposes a gas burner and an electrode, the hole for electrodes is formed in the two places where the hole for burners is mutually opposite. Therefore, the electrode can be exposed even if the top plate is rotated 180 degrees, and can be attached to the housing without minding the direction of the top plate. And even if the top plate is rotated 180 degrees in this way, since all the four corners of the top plate are rounded, as described above, it is possible to prevent unexpected movement and rollover of the tabletop stove.
By the way, if all the four corners of the top plate are rounded in this way, a large gap is created between the lid of the cylinder housing part adjacent to the top plate and the corner of the top plate, and food, dust, etc. enter here. Therefore, there is a risk of ignition. However, in the above configuration, the lid has a protruding portion that protrudes so as to be adjacent to the rounded portion of the top plate, so that such a large gap does not occur and the risk of fire can be prevented.

  As described above, the present invention can provide an easy-to-turn operation knob without changing the torque characteristics of the instrument itself, thereby providing a tabletop stove that can be easily controlled.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.
In addition, components having the same reference numerals in the drawings have the same configuration.

1 to 3 show a tabletop stove 1 according to an embodiment of the present invention. FIG. 1 is a perspective view showing a state in which a lid 22 of a cylinder accommodating portion 23 described later is opened, and FIG. FIG. 3 is a plan view of the vicinity of the heat source controller 27 and the operation knob 24 connected thereto in the cylinder accommodating portion 23 of FIG.
Since this tabletop stove 1 has a size and weight that can be carried, it can be used by carrying it on a table or the like of a table. On the tabletop stove 1, pots such as pots, kettles and iron plates are placed and used for cooking. The desktop stove 1 can also be used outdoors such as during camping and earthquakes. The tabletop stove 1 shown in the figure is a tabletop gas stove that uses fuel gas as a heat source, and is also called a portable gas stove, a cassette stove, or the like.

  The tabletop stove 1 includes a gas supply unit 4 that can supply gas by setting a cartridge-type gas cylinder 28, and a gas burner 12 that generates a flame using the gas supplied from the gas supply unit 4 as fuel. It comprises a combustion section 2 provided. The gas supply unit 4 and the combustion unit 2 of the present invention may be separated from each other, but the gas supply unit 4 and the combustion unit 2 of the present embodiment are integrated together by a housing 6.

In the case of this embodiment, the housing 6 is formed by applying heat-resistant coating to steel. However, the housing 6 is not limited thereto, and may be formed of, for example, an enamel having excellent heat resistance. The casing 6 has a substantially rectangular shape as a whole, and a plurality of leg portions 17 are provided on the bottom surface thereof.
And the housing | casing 6 has the cylinder accommodating part 23 in the gas supply part 4 side. The cylinder accommodating part 23 has a space S1 for accommodating the gas cylinder 28 and a lid 22 that can be opened and closed to cover the space S1.
The lid body 22 is rotatable in the R1 direction in the figure around a hinge 25 located at a position away from the combustion unit 2. Therefore, in the open state in which the lid body 22 of FIG. 1 is opened, the lid body 22 is opened facing the combustion section 2 side. In the closed state in which the lid body 22 of FIG. 2 is closed, the end surface 22a opposite to the hinge 25 of the lid body 22 is adjacent to the top plate 34 of the combustion unit 2.

  A heat source controller 27 that controls the supply amount of the heat source is fixed inside the cylinder housing portion 23. As shown in FIG. 3, the heat source controller 27 of the present embodiment includes a cylinder connection part 26 for making the gas cylinder 28 detachable, a flow rate control valve (not shown) for adjusting the degree of opening and closing of the gas flow path, And it has the governor 16 which is a pressure regulator. The gas in the gas cylinder 28 is supplied to the gas burner 12 of FIG. 1 while being mixed with air through the heat source controller 27, the gas conduit 14, and a gas / air mixer (not shown). The In addition, when the gas cylinder 28 is heated and the internal pressure rises abnormally, the cylinder connection part 26 is attached to and detached from the gas cylinder 28 by a magnet so that the safety mechanism is activated and removed.

  As the heat source controller 27 including the flow control valve, the governor 16 and the like, a publicly known one can be used. By rotating, the degree of opening and closing of the flow control valve is changed to supply the heat source (in this embodiment, fuel gas). An operating shaft 18 having a variable amount is provided. An operation knob (also referred to as “instrument plug knob”) 24 is connected to the operation shaft 18. The user can control the gas flow rate (including zero) supplied to the gas burner by rotating the operation knob 24 about the axial direction of the operation shaft 18.

As shown in FIGS. 1 to 3, the operation knob 24 is disposed so as to protrude from a lateral surface (a lateral surface on the front side in the figure) 6 b of the housing 6. Specifically, the operation knob 24 protrudes along the axial direction of the operation shaft 18 from the base 31 connected to the operation shaft 18 and is picked by a finger to rotate (the rotation shaft 18). 1 and a knob main body 30 which is operated in the R direction in FIG.
The base 30 has a plate-like cover disposed substantially parallel to the lateral surface 6 b and a protrusion 19 that rotates as the knob body 30 rotates. Then, when the knob main body 30 is turned, the projecting portion 19 pushes the igniter 38 to generate a pulse voltage, and this pulse voltage discharges the electrode 39 adjacent to the gas burner 12 of the combustion portion 2 to ignite the fuel gas. To do. The operation knob 24 will be described later in detail.

A gas burner 12 that receives fuel gas from a gas cylinder 28 and an ignition electrode 39 are accommodated on the combustion unit 2 side of the housing 6.
On the housing 6, a top plate 34 is disposed adjacent to the cylinder housing portion 23 and having a through hole 37 so as to expose the gas burner 12 and the electrode 39. The top plate 34 has a function of a juice tray that prevents intrusion of spilled trash and garbage into the appliance, and is detachable from the housing 6.

The through hole 37 of the top plate 34 includes a burner hole 40 for exposing the gas burner 12 and an electrode hole 41 for connecting the burner hole 40 to expose the electrode 39. The through-hole 37 is preferably as small as possible since it cannot be spilled if it is too large. Therefore, the burner hole 40 has a circular shape corresponding to the shape of the gas burner 12, and the electrode hole 41 is also a small hole corresponding to the electrode 39, so that the edge of the burner hole 40 is cut out substantially halfway. It has a circular shape.
The peripheral portion of the through hole 37 is a ring-shaped recess 33. The recess 33 is an inclined surface that gradually inclines toward the outer periphery, and can hold spilled parts and the like.

Furthermore, the top plate 34 according to the present embodiment is not only a function of the juice tray, but also serves as a foundation for Gotoku 8.
The five virtues 8 are fixed to the four corners of the upper surface of the top plate 34 and surround the gas burner 12 with four five virtues 8. The Gotoku 8 has a leg portion 36 connected to the top plate 34 and a mounting portion 13 that is formed integrally with the leg portion 36 and on which pans such as a pan, a frying pan, a kettle, and an iron plate are placed. . In addition, although the five virtues 8 of this embodiment are four, three may be sufficient and five or more may be sufficient.
The leg portion 36 has a notch portion 36a in the vicinity of the boundary with the placement portion 13 in order to reduce the weight. The mounting part 13 extends from the upper part of the leg part 36 toward the gas burner 12, and the upper surface thereof becomes the mounting surface 15 on which the pans are placed.

The tabletop stove 1 of the present embodiment has the above characteristics and further has the following characteristics.
[Case and top plate]
First, the housing | casing 6 and the top plate 34 are demonstrated using FIG.1 and FIG.2.
The casing 6 has two rounded corners 6a opposite to the gas supply part 4 having the cylinder accommodating part 23 in plan view (that is, curved so as to protrude outward). doing). Also, the top plate 34 placed on the housing 6 has a rounded corner 34a, similarly to the rounded corner 6a of the housing 6. Accordingly, the tabletop stove 1 has a small area at the corner opposite to the gas supply unit 4 so that it is difficult for objects and human bodies to hit it. .
Furthermore, since the rounded round shape of the top plate 34 is formed at all four corners 34a in plan view, the gas supply part 4 of the tabletop stove 1 can be mounted even if it is rotated 180 degrees and attached to the housing 6. The corner on the opposite side is rounded.

  Further, with respect to the through hole 37 of the top plate 34, the electrode hole 41 is formed at two locations opposite to each other of the burner hole 40. In the case of the figure, two electrode holes 41 and 41 are formed so as to be cut out in a substantially semicircular shape at a position opposite to the edge of the circular electrode hole 41. Accordingly, the through-hole 37 is symmetrical on the side of the one electrode hole 41 and the other electrode hole 41, and the electrode 19 is exposed even if the top plate 34 is rotated 180 degrees, and the direction of the top plate 34 is not observed. It can be attached to the housing 6 without making it. And even if the top plate is rotated 180 degrees in this way, since the four corners 34a of the top plate 34 are all rounded as described above, it is possible to prevent the tabletop stove 1 from being unexpectedly moved or overturned. The number of electrode holes 41 in the figure is two, but may be three or more.

[Cover of cylinder housing part]
Next, the lid body 22 of the cylinder accommodating portion 23 will be described with reference to FIGS. 1 and 2.
The lid body 22 has a projecting portion 43 projecting so as to be adjacent to the rounded portion of the top plate 34 in a closed and closed state. That is, the projecting portions 43 are formed on both end portions in the direction Y orthogonal to the rotation direction R1 on the end surface 22a of the lid body 22 on the top plate 34 side. The edges of the protrusions 43 are shaped along the rounded corners of the four corners of the top plate 34. For this reason, in the closed state of FIG. 2, only a slight gap is generated between the protrusion 43 and the corner 34 a of the top plate 34. Therefore, even if all the four corners 34a of the top plate 34 are rounded, the risk of food, dust, etc. entering between the top plate 34 and the lid 22 can be reduced.
Note that the shape of the protrusion 43 does not completely correspond to the rounded shape of the corner 34a of the top plate 34, and the outer end is rounded. Therefore, the protrusion 43 does not become sharp, and injury in the opened state of FIG. 1 is prevented.

[About the five virtues]
Next, Gotoku 8 will be described mainly with reference to FIG. FIG. 4 is a plan view of Gotoku 8.
As shown in FIG. 4, the placement surface 15 on which the pots of Gotoku 8 are placed has the largest width W1 of the central portion 15a in the longitudinal direction, and gradually increases in width from the central portion 15a toward the tip 15b and the root 15c. Is narrower. When the outer peripheral portion of the pan bottom is placed on the central portion 15a, the central portion 15a is positioned so as not to protrude from the top plate 34 shown in FIG. The top plate 34 is 7-9 cm from the four corners 34a. The maximum width W1 of the central portion 15a in FIG. 4 is about 6 mm, which is about twice the width W2 of the tip 15b and the root 15c, but the present invention is not limited to this. Thereby, the impression which is stabilized by visually placing the pots on the central portion 15a is given to the user, and the user can be guided to select the pots having a preferable size. Therefore, a small pot can be arranged only at the tip 15b to prevent the possibility of falling from the virtues 8, and the use of large pots that protrude from the top plate 34 is suppressed, and the pots are placed on the cylinder accommodating portion 23. It is possible to prevent the gas cylinder from being heated by arranging the gas cylinder.

[About the operation knob]
Next, the operation knob 24 will be described mainly with reference to FIGS. 5A is a side view of the operation knob 24, FIG. 5B is a front view of the operation knob 24, and FIG. 6 is a perspective view of the vicinity of the operation knob 24. FIG.
As described above, the operation knob 24 has a knob main body 30 that protrudes from the lateral surface of the casing and is rotated by being picked by the fingers FG1 and FG2. The knob main body 30 has an axial direction of rotation. (Axial direction of the operation shaft 18) Compared to the projecting dimension D1 of the central region 30a in X, the projecting dimension D2 of both end portions 30b and 30c formed by extending away from the central region 30a is larger. . Accordingly, since the central region 30a has a small degree of protrusion, the fingers FG1, FG2 are guided to both end portions 30b, 30c, and the user naturally moves the fingers FG1, FG1, toward the both end portions 30b, 30c as shown in FIG. FG2 will be assigned. Therefore, the distance between the position of the fingers FG1 and FG2 on which the force is applied and the operation shaft 18 is increased, and the knob body 30 can be easily turned without changing the torque characteristics of the instrument itself. In fact, when an experiment was performed using the conventional operation knob in which the torque characteristics of the instrument itself did not change and the operation knob 24 of the present embodiment, it was possible to obtain an impression that it was easy to turn from 20 out of 20 persons.
The “projection dimension” referred to here is a dimension projecting from the lateral surface of the housing. The “both ends” refer to regions on both sides in the longitudinal direction Y with respect to the central region 30a.

Specifically, in the present embodiment, the protruding dimension D2 of the one end 30b and the other end 30c is the same (however, the configuration of the present invention is not limited to this).
The knob body 30 is generally a column that is long in one direction Y perpendicular to the axial direction X of the operation shaft 18, and has a height dimension H1 along the one direction Y and a central axis direction X. In the drawing, H1 is about 45 mm, D2 is about 15 mm, and W3 is about 13 mm.
And the central area | region 30a of one direction (longitudinal direction) Y of the front facing a user is depressed and formed. The central region 30a may not be greatly recessed as long as it can be clearly seen that both end portions 30b and 30c protrude. For example, in the case of the knob main body 30 shown in the figure, the front surfaces of both end portions 30b and 30c are inclined surfaces 30d that are inclined so as to gradually become deeper toward the central region 30a from both ends in the longitudinal direction Y (toward the housing side). At the same time, the central region 30a is curved and recessed (the maximum recess dimension D3 in the figure is about 2 mm). Thereby, even if the central region 30a is not greatly depressed to the left, a depressed impression can be given to the user. Accordingly, it is possible to prevent a situation in which an object or a person is caught in the depressed central region 30a and the tabletop stove is turned over.

In addition, the widths of the both end portions 30b and 30c gradually increase as the distance from the central region 30a increases. For this reason, both side surfaces 30e and 30e when the knob main body 30 is viewed from the front are similarly inclined ( In the figure, the inclination angle θ is about 2 degrees, but the present invention is not limited to this, and the inclination angle θ can be suitably implemented within about 2 to 5 degrees). In other words, the both side surfaces 30e, 30e are inclined so as to be separated from each other toward the edge in the longitudinal direction Y. Therefore, when the knob body 30 is rotated, the fingers are easily caught on the inclined surface, and the force for pinching the both end portions 30b and 30c may be weakened, and the knob body 30 is easily rotated accordingly.
As shown in FIG. 5 (A), the corners (hereinafter referred to as “casing side corners”) 30f on both sides in the longitudinal direction Y of the knob body 30 are chamfered. And as shown in FIG. 3 which can planarly view this housing | casing side corner | angular part 30f, inner side S2 of the knob | pick main body 30 is a cavity.

Although the embodiment of the present invention is configured in a preferable aspect as described above, the present invention is not limited to this aspect. For example, the desktop stove according to the present embodiment uses fuel gas as a heat source, but may be an electric type.
In addition, the operation knob of the present invention may have the shape shown in FIGS. In these drawings, only the knob main body, which is one of the characteristic parts for the present invention, is indicated by a solid line, and the other parts are indicated by broken lines.
FIGS. 7 to 14 show a first modification, which is substantially the same as the embodiment of FIGS. 1 to 6 (hereinafter referred to as “the above embodiment”), and is inclined on both sides when the knob main body is viewed from the front. The only difference is that the angle is exactly 2 degrees.
FIGS. 15-21 is a 2nd modification, and the upper side at the time of arrange | positioning a longitudinal direction perpendicular | vertical compared with the said embodiment, when the front view of a knob | pick main body is an ellipse shape, a width dimension is slightly small. The difference is that a hole is formed at the end of the. The rear view of the second modification is the same as FIG. 8, and the bottom perspective view is the same as FIG.
22 to 26 show a third modification, which is mainly different from the above-described embodiment in that the depression method in the central region of the knob body is large. The rear view of the third modification is the same as FIG. 8, and the bottom perspective view is the same as FIG.

FIGS. 27 to 76 are fourth to thirteenth modified examples of the knob main body as viewed from the front so that the width dimension gradually increases as the distance from the central region increases as compared to the above embodiment. The difference is that the side surfaces are not inclined, and the following points are mainly different. In the fourth to thirteenth modifications, each rear view is the same as FIG. 8, and each bottom side perspective view is the same as FIG.
27 to 31 of the fourth modification, as compared with the above-described embodiment, the front side of both ends of the knob body is inclined so as to become deeper from the center toward both ends, and the casing side corners are chamfered. The difference is that it is not, and the way of depression in the central area is large.
32 to 36 of the fifth modified example are different from the above embodiment in that both end portions in the longitudinal direction of the knob main body are substantially rectangular and that the depression in the central region is large.
37 to 41 of the sixth modified example are different from the above embodiment in that the front surfaces of both ends of the knob main body are not inclined and the center region is greatly recessed.
42 to 46 of the seventh modification, compared to the above embodiment, the corner on the front side of the knob body is curved, the corner on the housing side is not chamfered, and the depression in the center region Is different.
47 to 51 of the eighth modification are different from the above embodiment in that the front surfaces of both ends of the knob body are curved and the depression in the central region is large.
52 to 56 of the ninth modified example are different from the above embodiment in that the depression method in the central region of the knob body is small.
57 to 61 of the tenth modification, compared to the above-described embodiment, the point that the front faces of both ends of the knob body are inclined so as to be deeper from the center toward both ends, and the depression in the center region is small. The point is different. In the case of the tenth modified example, most of the both end portions have smaller projecting dimensions than the central region, and thus cannot necessarily be said to be a modified example of the above embodiment. However, the depression of the central region does not mean that the fingers cannot be guided at both ends.
62 to 66 of the eleventh modification are different from the above embodiment in that the front surface of both ends of the knob body is curved and the depression in the central region is small.
In FIGS. 67 to 71 of the twelfth modification, compared to the above-described embodiment, the central region of the knob body is not depressed but completely cut out, and there are only both ends, and The difference is that the corners at both ends are rounded. Thus, a knob body having only both ends is also an embodiment of the present invention.
72 to 76 of the thirteenth modification are different from the above embodiment in that only both ends exist and the side surfaces of both ends are inclined, as in the twelfth modification.
