Description

Description: TECHNICAL FIELD The present invention relates to a stove, and more particularly to improvement of a push button arranged on the front surface of a main body case of the stove.

[Prior Art] Conventionally, there has been a stove provided with an operation knob for operating an opening / closing valve of a fuel passage on an operation panel arranged on a front surface of a main body case.

In such a stove, for example, a gas stove in which a push button for operating an on-off valve is arranged in a state of protruding forward in an opening of a front panel of a main body case is also proposed (Japanese Utility Model Publication No. 60-91952). ). In this gas stove, when a certain operating force is applied to the touch portion of the push button, the push button is rotated about a certain fulcrum to drive the operating rod of the open / close valve, thereby shifting the open / close valve to the open side. Therefore, the fuel gas is supplied to the burner head of the gas burner.

[Problems to be Solved by the Invention] However, in the above-described conventional gas stove, since a small push button that is arranged on a part of the front panel is provided, the area of the touch portion of the push button is very small. It was in the range. In addition, the push button requires a large operating force to operate the on-off valve that is in the closed state when the gas stove is not used, but in the case of a push button with a very small touch area, one finger can be used. You must operate the push button by touching the touch part. For this reason, it may be difficult for a user having a weak operating force to perform the ignition operation of the gas burner. Therefore, in such a gas stove, there is a problem that it is very difficult for the user to operate the push button.

Further, since the conventional push button is disposed in the opening of the front panel so as to project forward, the front surface of the main body case has an uneven shape. For this reason, it cannot be said that the front shape has a simple design, and it has been a cause of impairing aesthetics.

The present invention can easily operate the push button,
Moreover, the aim is to provide a stove with a beautiful appearance.

[Means for Solving the Problem] The invention according to claim 1 is a main body case, a heat source attached to the main body case, an opening / closing means for opening and closing a passage for supplying energy to the heat source, and the main body. A stove arranged in a case and provided with a push button for operating the opening / closing means, wherein the push button partitions a front surface of the main body case in a width direction, and an upper end of the push button is rotatable with respect to the main body case. A movable partition plate supported and swinging about an upper end thereof, the movable partition plate forming a part of a front panel of the main body case, and the front part from the main body case when not operated. In the state of being lifted, a technical means is used which is located on the same plane as the other part of the front panel of the main body case.

A flat plate-shaped grill door may be provided on the front surface of the main body case, and a flat plate-shaped touch portion located on the same plane as the grill door when not in operation may be provided on the push button.

Further, the push button may be provided with a biasing unit that biases the lower end portion of the one movable partition plate in a direction in which the lower end portion of the one movable partition plate is separated from the main body case forward.

Further, the main body case may be provided with an operation lever that operates differently from the push button, and the push button may be formed with an insertion hole for inserting the operation lever in a horizontal direction.

[Operation] According to the invention described in claim 1, the push button is configured by the movable partition plate that partitions the front surface of the main body case in the width direction. Since the movable partition plate, which is the push button, is provided so as to be flush with the other part of the front panel of the main body case in a state of being lifted forward from the main body case when not operated, The area is very wide compared to the conventional one. Further, since the push button constitutes a part of the front panel of the main body case, the front surface of the main body case does not have an uneven shape.

[Effects of the Invention] Since the push button can be operated by touching it with a plurality of fingers or palms, the push button can be easily operated. Therefore, the opening / closing means operates accurately.

In addition, since the front surface of the main body case has a planar shape, the front surface can have a very simple design, and thus it is possible to provide a stove with an excellent appearance.

The end piece 29 is located on the side of the push button 5 and covers the space S in which the push button 5 appears and disappears from the side. Further, since this embodiment is the table gas stove 1 with grilled fish grill, the space S is covered from the side by the grill chamber side wall 24a like the end piece 29.

The gas burner 3 is the heat source of the present invention and has an air hole 31, a mixing tube 32 and a burner head 33. The mixing pipe 32 is provided with a fuel gas and an air hole 31 ejected from a nozzle 44 described later.
Mix with the air sucked in from inside. Burner head
33 is arranged in a state of protruding above the opening 25 of the ceiling plate 22 and has flame holes appropriately arranged. Also,
A thermocouple 34, which generates an electromotive force when heat generated by a flame is detected, is arranged beside the burner head 33. The gas burner 3 ejects the air-fuel mixture that has passed through the mixing pipe 32 and reached the burner head 33 from the flame holes to burn the air-fuel mixture.

The gas shutoff valve 4 is the opening / closing means of the present invention, and is a body fixed to the main body case 2 via a mounting bracket (not shown).
At 40, a gas passage 41 for supplying fuel gas to the gas burner 3 is formed. The gas passage 41 is a passage of the present invention, in which a tubular member 43 communicating with the gas supply pipe 42 is fitted on the inlet side, and a nozzle 44 for ejecting fuel gas into the gas burner 3 is fitted on the outlet side.

A first valve body 45 and a second valve body 46 are arranged in the body 40.

The first valve body 45 and the second valve body 46 open the gas passage 41 when the operating rods 47, 48 move to the left side in the drawing. The first valve body 45 and the second valve body 46 close the gas passage 41 when the operating rods 47 and 48 return to the positions shown in FIG. Further, when the operation rods 47 and 48 are brought into contact with the operation rod 49 which is in contact with the push button 5, the operation rods 47 and 48 are operated.
Move in conjunction with 49. A spring 50 for urging the operating rod 49 to the right side in the drawing is arranged between the operating rod 49 and the body 40.

The operating rod 49 is set at three positions of a starting end position A, an end position B, and an intermediate position C by a known push-push mechanism P.

At the starting end position A, since the operating rod 49 does not push the operating rods 47 and 48, the operating rods 47 and 48 do not move and the first valve body 45 and the second valve body are not moved.
The gas passage 41 is closed by 46.

At the terminal position B, since the operating rod 49 pushes both the operating rods 47 and 48, the operating rods 47 and 48 move and the first valve body 45 and the second valve body 46 open the gas passage 41 and the gas passage 41. The fuel gas that has entered from the inlet 41a flows through both the first passage 41b and the second passage 41c to the outlet 41d.

At the intermediate position C, the first valve body 45 closes the second passage 41c, but the first passage 41b is opened, so that the throttle valve 7 adjusts the throttle of the fuel gas.

The plurality of push buttons 5 are a plurality of movable partition plates (movable panels) that partition the front surface of the main body case 2 in the width direction, and are made of resin and have a flat plate shape when not pressed by the user (non-operated). It has a large flat plate-shaped touch portion 51 located on the same plane as the grill door 24 and the fixed partition plate (fixed panel) 91. In addition, the fixed partition plate 91 is the main body case 2
It constitutes the other part of the front panel 9 and is attached to the front surface of the front frame portion 23.

The plurality of push buttons 5 are provided in front of the front frame portion 23 of the main body case 2 from the upper end portion to the lower end portion so as to be wide, and along the shape of the front frame portion 23. When the push buttons 5 are not pressed, the main body case 2
It is arranged so as to be positioned on the same plane as the grill door 24 and the fixed partition plate 91 (initial position) in a state of being slightly raised from the front frame portion 23 toward the front. On the back side of the upper portion of the push button 5, there is formed a support shaft 52 rotatably (swingably) arranged on a support portion 26 provided on the upper portion of the front frame portion 23. Then, an insertion hole 53 through which the operation lever 61 is inserted is formed in the left and right direction on the upper portion of the push button 5.
In addition, between the lower back side of the push button 5 and the front frame portion 23,
A spring 54 is provided.

The spring 54 is a coil spring for returning the push button 5 to the initial position, and is a biasing means for biasing the lower end portion of the push button 5 in the direction away from the front frame portion 23 of the main body case 2 forward. . Further, the back side of the lower part of the push button 5 is pushed by the spring force of the spring 54.
An engaging piece 55 that engages with an engaging hole 27 formed in the front frame portion 23 is integrally formed so as not to separate from the front frame portion 23. And, on the back side of the central part of the push button 5, the front frame part
A bulging portion 56 bulging in the 23 direction is formed. The operating rod 49 of the gas cutoff valve 4 is always in contact with the bulging portion 56. Therefore, in this embodiment, the push button 5 takes the forward position by the spring 54 even if the operating rod 49 is held at the intermediate position C by the push / push mechanism P. However, the bulging portion 56 and the operating rod 49 may be connected to each other so that the operating rod 49 can be moved forward and backward in accordance with the retracted state of the operating rod 49. in this case,
The spring 54 is unnecessary. When the second valve body 46 is replaced with a normal valve body, or when a normal valve body is added, the valve is opened when the operating rod 49 is locked at the intermediate position C by the push / push mechanism P. It will be in the state where it was done.

The iris operation knob 6 includes an operation lever 61, a shaft 62 and a pin 63.
And operates the throttle valve 7 and the damper 8.

The throttle valve 7 is operated by sliding the throttle control knob 6
Through the operation lever 61 that swings around 62 and the pin 63 that is rotated by this operation lever 61, the displacement is changed in the vertical direction to change the degree of throttling of the first passage 41b of the gas passage 41.

The damper 8 changes the opening degree of the air hole 31 of the gas burner 3.

Therefore, the operation lever 61 also has a function of moving the damper 8 and adjusting the amount of air flowing into the gas burner 3 by shifting the insertion hole 53 of the push button 5 in the left-right direction.

The operation of the table gas stove 1 of this embodiment will be described with reference to FIGS.

The conventional push button is arranged in the opening of the front panel so as to project forward, and the front surface of the main body case has an uneven shape. Therefore, the plurality of push buttons 5 of this embodiment are arranged so as to form the front panel 9 of the main body case 2 together with the fixed partition plate 91. For this reason, the front surface shape of the main body case 2 does not become uneven, and the front surface shape of the main body case 2 becomes a planar shape,
The front shape can be very simple. Therefore, it is possible to provide the table gas stove 1 having an excellent appearance.

The touch portion 51 of the push button 5 forming a part of the front panel 9 of the main body case 2 is formed in the size of an adult's palm. For this reason, the range of the touch section 51 is extremely wide as compared with the touch section of the conventional push button. That is, the user can touch the touch portion 51 with a plurality of fingers or a palm. Therefore, even a user having a weak operating force can easily push the push button 5 by overcoming the spring force of the spring 54 or the like.

As described above, when the user presses the push button 5, the operating rod 49 of the gas cutoff valve 4 that is in contact with the bulging portion 56 formed on the back side of the push button 5 overcomes the spring force of the spring 50 and is illustrated. It moves to the left and contacts the operating rod 47.
Therefore, the operating rod 47 also moves in the leftward direction in the drawing in conjunction with the push button 5, so that the first valve body 45 opens the first passage 41b of the gas passage 41 formed in the body 40. As a result, even if the throttle valve 7 is in the throttled state, the second passage 41c is opened while the push button 5 is being pressed, so that a large amount of fuel gas is supplied to the gas burner 3 and ignition is easy. At this time, since the operating rod 49 is also in contact with the operating rod 48, the second valve body 46 opens the gas passage 41. The second valve body 46 is composed of an electromagnetic safety valve, and is kept open even if the push button 5 is released by the electromotive force generated by heating the thermocouple 34 by the flame.

Therefore, the fuel gas is ejected from the gas supply pipe 42 into the gas burner 3 through the tubular member 43, the gas passage 41 and the nozzle 44. Therefore, air is sucked through the air holes 31 due to the suction effect of the fuel gas ejected from the nozzle 44. After that, the air-fuel mixture of the fuel gas and the air reaches the burner head 33 through the mixing pipe 32, and is ejected from a large number of flame holes and burned.

(Modification) In the present embodiment, the present invention is used for the table gas stove having a plurality of gas burners, but the present invention may be used for the stove having one burner.

In this embodiment, the fuel gas is used as the energy (fuel), but liquid fuel may be used as the fuel. Moreover, you may use an electric heater as a heat source.

In the present embodiment, the touch portion of the push button has a doglegged plate shape, but the push button 5 is the front panel 9 of the main body case 2.
Any shape may be used as long as it constitutes a part (movable partition plate).

In this embodiment, the gas cutoff valve is used as the opening / closing means, but the shape, operation and structure can be freely changed as long as the passage for supplying the fuel to the burner is opened / closed and operated by the push button. Further, as the opening / closing means, a switch that connects and disconnects the electric heater and the power source when the heat source is the electric heater is used.
