Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a cassette stove.

(Prior art) In order to set the gas cylinder used in a cassette stove so that the gas in the gas cylinder is discharged from the valve nozzle, a mechanism is required to push the valve nozzle against a spring that is always acting in the valve closing direction. Conventionally, in order to push in the cylinder from the rear end, a cylinder attaching/detaching device consisting of a slide lever and its operating mechanism had to be installed, making a cassette-type stove complicated. In addition, the operation was troublesome because it was necessary to hold the nozzle side and the bottom of the cylinder in two places to attach and detach the cylinder.

(Technical Problem) The present invention was made in order to solve the above-mentioned points.The problem is that the gas cylinder can be installed more reliably without the need for a complicated cylinder attachment/detaching device, and is better than the conventional attachment/detachment device. The purpose is to make it easy to install, and to significantly simplify the structure of the stove, thereby reducing costs.

(Technical means) In order to achieve the above-mentioned problem, the present invention provides a stove body 1.
This is a cassette stove in which the gas cylinder 13 is attached by pushing the nozzle side of the gas cylinder 13 into the substantially cylindrical socket 3 of the governor 2 installed at the 0. guide protrusions 1 and 7 which are formed into engagement ports 5 and 6 and which engage into the engagement ports 5 and 6 when the gas cylinder 13 is correctly installed in the socket 3;
are respectively installed on the outer periphery of the socket 3, and when the guide protrusions 1 and 7 are engaged with the engagement ports 5 and 6,
Further, grooves 1a and 7 that can be engaged with the edges of the engagement ports 5 and 6 in order to hold the gas cylinder with the flange 4.
The guide protrusions 1, 7 are provided with hook portions 8, 9 having a diameter of "a".

(Embodiment) To explain with reference to the illustrated embodiment, the gas cylinder 13 to be used has a flange 4 at the tip thereof, and a notched engagement opening 5 for positioning is provided therein. This notch-shaped engagement opening 5 corresponds to the direction of the bent end of the siphon pipe 14, as shown in FIG.

The stove body 10 has a governor 2 at one corner, and the gas cylinder 1 is placed inside the cylindrical socket 3.
In order to fit the valve nozzle 15 of No. 3 in a pushed state, the following engagement and holding structure is provided.

Two guide protrusions are provided in the embodiment, and one guide protrusion 1 that engages with the notch-shaped engagement opening 5 is located on the upper outer periphery of the cylindrical socket 3 as in the conventional one, but the other guide protrusion 7 is provided at a position approximately 180 degrees apart from this, that is, at the bottom of the outer periphery of the socket 3.

One of the guide protrusions 1 has a width ₁ that allows it to engage only one of the engagement ports 5, and after engagement, it enters the groove 1a, which is an engagement means provided at the base of the guide protrusion 1, and locks the hook at the tip of the protrusion. It is set so as to be hooked on and engaged with the portion 8. Since the groove 1a engages with the side of the notched engagement opening 5 at the pushed-in position where the valve nozzle 15 opens, the flange 4 is subjected to the action force of the nozzle biasing spring. In order to counter this and withstand repeated attachment and detachment, the flange 4 is preferably made to have higher strength than conventional ones.

The other guide protrusion 7 has a width ₂ that allows it to engage only the other engagement opening 6, and further engages with a groove 7a provided at the base of the guide protrusion 7 as an engagement means after engagement. Therefore, the hook portion 9 at the tip of the projection engages with the edge of the window frame-shaped engagement opening 6. Both guide protrusions 1, 7
are distinguished by shape, with one side shaped like a notch and the other side shaped like a window frame, and the widths are set to ₁ > ₂ , and the width ₃ of the notch-like engagement port 5 and the width ₄ of the window-like engagement port 6 are _3.
> ₄ and ₁ > ₄ to prevent accidental engagement with each other. The number of the guide protrusions 1, 7 and the engagement ports 5, 6 is not limited to two, but may be three or more. If the number is increased, the stability will be increased, but it will become more troublesome to attach and detach, so two or three locations are preferable. In each figure, 16 indicates a gas discharge pipe provided in the governor 2, 17 indicates a burner installation portion to be connected thereto, and 18 indicates a heat radiation port.

(Operation of the invention) In the cut stove constructed as described above, the tip valve nozzle 15 of the gas cylinder 13 is applied to the socket 3 of the governor 2, and the notch-like engagement portion 5 is attached to one of the guide protrusions 1 attached to the governor 2. , the other engaging port 6 is engaged with the other side protrusion, and the groove 1 is further inserted into the groove 1.
By rotating the entire gas cylinder 13 to the depths of the gas cylinders a and 7a, it can be hooked onto the hooks 8 and 9, and the gas cylinder 13 can be permanently held in the state where the valve nozzle is opened.

(Effects of the invention) Therefore, according to the invention, the gas cylinder 13 can be attached and detached from the gas stove at the flange 4, so there is no need for a complicated cylinder attachment/detachment device as in the past, and the structure of the cassette stove can be changed. It is possible to significantly simplify the process, and as a result, the cost can be significantly reduced. In particular, since the gas cylinder 13 is set by engaging only the flange 4, it is not necessary to operate with both hands as in the conventional case, and it is easy to attach and detach with one hand. Since the gas cylinder pair itself can use the conventional notch-shaped engagement port 5, the only modification required is to provide another engagement port 6, and implementation is easy. Furthermore, since the structure is simple and easy to operate, unreasonable handling operations are less likely to occur, reducing the risk of gas leakage and increasing safety.
