Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a so-called cassette-type gas stove that uses a small gas cylinder as a combustion source in which a small gas cylinder is detachably incorporated, and in particular, one that has a handheld handle on the side of the body. It is related to.

(Prior technology) This type of cassette type gas stove was first developed in 1983.
It is known from Publication No. -81502.

This device has a combustion section on the front side of the vessel, and a gas cylinder storage section on the back side of the combustion section.

The accommodating portion has an access port at the bottom of the container, and an operating member for connecting and disconnecting the gas cylinder to the combustion appliance is provided as a lid member that is removably fitted to the access port.

(Problem to be solved by the invention) However, in the conventional structure, when a gas cylinder is housed in the container and connected to a combustion appliance, and when the connection is broken to take out or replace the gas cylinder, it is difficult to do so each time. Since the device must be tilted or upside down, the work is time-consuming and inconvenient to use.

To solve this problem, it is conceivable to provide the insertion/exit port and the operation member for connection/disconnection on the back or side surface of the container body. However, if such a configuration is simply used, the lids and operating members of the loading/unloading ports often interfere with the carrying handle of the container, which is kept lying down except when the container is being carried. Since it gets in the way, it is still inconvenient to use.

Therefore, the present invention takes advantage of the fact that the handbag handle is regulated in position so that it is not affected by the combustion part, and makes improvements in relation to the installation positions of the opening and operating member and the positional regulation of the handbag handle. The object of the present invention is to provide a cassette-type gas stove that can solve the above-mentioned conventional problems.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a combustion section on the front side of a body used to house gas cylinders, and an opening for the gas cylinders to be opened and closed at the lower part of the back side. It is provided with a lid, and an operating member for connecting or disconnecting the gas cylinder to the combustion appliance is provided at the lower side of the body, and a carrying handle connects both ends of the gas cylinder to the inlet/outlet on the side of the body and the operating member. The handheld handle is pivoted at a higher level than the installation height, and the range of rotation about the pivoted handle is tilted slightly backwards from the upright position, and the back of the device does not reach the position of the loading/unloading port or operating member. It is characterized by being regulated between a prone position and a prone position to the side.

(Function) According to the above structure of the present invention, since the gas cylinder inlet/outlet is provided at the lower part of the back of the container,
You can open and close the lid and put in and take out the gas cylinder without having to topple or turn the container upside down.The operating member is also located at the bottom of the side of the container, so there is no need to topple or turn the container upside down. The gas cylinder housed inside the container can be connected to or disconnected from the combustion appliance by simply operating the gas cylinder.

Both ends of the handbag handle are pivotally supported on the upper part of the device body, and the range of rotation of the handbag handle around the pivot support ranges from an upright state to a slightly backwardly tilted handheld position, the opening and the operation Thermal safety of the handheld handle is ensured because it is restricted between the prone position and the position where it does not reach the parts, and is not rotated to a position where it is exposed to combustion heat from the combustion part on the front side. Since it is not rotated to a position that interferes with the loading/unloading port or the operating member, it can be stored in a position that does not interfere with the work and does not interfere with the operation.

These hot air release structures and the heat shield plate 36 prevent the inside of the vessel 3 from becoming abnormally heated due to the combustion heat of the gas, and prevent the inside of the vessel 3 from being heated as a fuel source. Thermal safety of gas cylinders 51 and the like is ensured.

On the front of the vessel body 3, a protective net 48 that largely encloses the front part of the upright chamber 1 and the upper part of the overhanging chamber 2 can be attached and detached by using its own elasticity and fitting the wire end 48a into the mounting hole of the vessel body 3. installed on.

The gas cylinder 51 is connected to the burner unit 21 on the bottom plate 9.
It is designed to be loaded at the bottom of the upright chamber 1 at the rear of the installation section. Gas cylinder 51 on bottom plate 9
A concave portion 52 is formed in the portion where the gas cylinder 51 is loaded so that the gas cylinder 51 can be received and stabilized. A gas pressure regulator 54 having a cylinder connection port 53 as shown in FIG. 2 is installed near one end of the concave portion 52 of the bottom plate 9.

The gas pressure regulator 54 regulates the pressure of the gas flowing out from the gas cylinder 51 connected to the cylinder connection port 53 and sends it to the pipe line 55. The conduit 55 is connected to the back side of one side of the top plate 5 of the upright chamber 1 through a metal fitting 56 with a screw 57.
It is connected to an instrument socket 59 with a gas passage blocking mechanism 58 attached thereto, communicates with another pipe 60 via the instrument socket 59 and the gas passage blocking mechanism, and is connected to the burner unit 21 through the pipe 60 after pressure regulation. It is designed to deliver gas of

The appliance pot 59 has an operation knob 6 on the top of the top plate 5.
It is opened by pushing and turning the operating rod 62 holding 1,
The supply gas sent from the pipe line 55 is sent to the pipe line 60. An automatic ignition mechanism 63 that is activated during the opening operation is assembled in the appliance pot 59, and a spark plug 64 of the automatic ignition mechanism 63 is assembled.
As shown in Figures 1 and 2, burner unit 2
It is arranged close to the flame port 21a of No. 1. As a result, the automatic ignition mechanism 63 is activated by the spark plug 64.
A spark discharge is caused at the flame port 21a, and the gas flowing out from the flame port 21a is ignited when the appliance pot 59 is opened.

The gas passage shutoff mechanism 58 is a known one, and is connected to a known tip-over switch 71 and a flameless detection sensor 72 for detecting a flameless state by an electric circuit 73. When these detect the tip-over of the container 3 or a flameless state, they are activated.
Separately from the appliance cock 59, the communication path between the pipeline 55 and the pipeline 60 is cut off to cut off the gas supply, and combustion in the event of a fall or the outflow of flameless gas, i.e., the outflow of raw gas, is immediately stopped.

The overturning switch 71 is provided next to the burner unit 21 on the bottom plate 9, but the burner unit 21 is covered with a heat shield cover 74 provided on the bottom plate 9 on both the left and right sides, the back side, and the top surface. , the thermal influence from around the burner unit 21 is alleviated. The heat shielding cover 74 is constructed by fitting the bent pieces 74f provided at two places on the lower end of one side into the holes in the bottom surface 9 and bending and locking them on the back side of the bottom surface 9. The top plate 7 is attached to the supporting metal fittings 118, which are attached to the sides of the unit, and one of which has two upper prongs attached to which the spark plug 64 is attached, and the other end of which is bent by fitting into the hole 74f of the heat shield cover 74.
By fixing 4a with screws 119, the bottom surface 9

The heat shielding cover 74 forms a passage 75 between its top plate 74a and the top plate 7 of the overhanging chamber 2, and the upwardly bent edge 74b formed at the front edge of the top plate 74a restricts ventilation in the front part of the passage 75. The upward airflow generated under the top plate 7 is reflected by the reflecting plate 36.
The hot air can be actively guided to the back side of the hot air passage 42, and the heat dissipation from the burner unit 21 to the inside of the vessel 3 is further suppressed by the cover. The front side opening of the heat shielding cover 74 and the opening 74c and notches 74d and 74e in the peripheral wall are formed on the bottom plate 9.
Together with the ventilation holes 47 and the like provided therein, it serves as a supply path for gas combustion air.

An operating lever 82 of a cylinder setting mechanism 81 is pivotally attached to the side surface of the gas pressure regulator 54 via a shaft 83, and an operating portion 82a protrudes to one side of the container body 3. As shown in FIGS. 1 and 2, the cylinder setting mechanism 81 is applied from below to the bottom of the recess 52 of the bottom plate 9, and both front and rear ends 83a and 83b are attached to the recess 52.
A cylinder pressing slide plate 83 is slidably mounted on the upper surface through a window 84, and an operating lever 82 is connected to a front end 83a of the cylinder pressing slide plate 83 via a shaft 85 and a cam hole (not shown). By moving the operating lever 82 up and down about a shaft 83, the phone pressing slide plate 83 is moved back and forth.

The cylinder pressing slide plate 83 has a cylinder pressing piece 83c bent upward at the rear end 83b.
When the gas cylinder 51 is moved forward toward the gas pressure regulator 54 side, the cylinder pressing piece 83c presses the gas cylinder 51 located in the concave portion 52 toward the gas pressure regulator 54 side to connect it to the cylinder connection port 53, and vice versa. When the gas cylinder 51 is moved backward, the pressure connection of the gas cylinder 51 is released. The cylinder pressing slide plate 83 is biased in the direction of releasing the cylinder pressing connection by a spring 86 acting between it and the bottom plate 9, and the cylinder pressing connection state is determined by the shaft 85 connecting the operating lever 82 and the cam hole. Relationships have become more stable.

An inlet/outlet 91 for the gas cylinder 51 is provided at the lower part of the back surface of the container body 3, and a door 92 for opening and closing the door 92 is pivotally connected to the lower part of both side edges of the inlet/outlet 91 by a shaft 93 so as to be freely openable and closable. The upper end of the door 92 is the entrance 9
A leaf spring 94 is attached to the upper part of the door 92 at a bent edge 91b that is bent inward from the stepped edge 91a, and the closed position is regulated by contacting the stepped edge 91a formed on the upper edge of the door 92. are elastically engaged with each other to be elastically locked in the closed position.
At the center of the upper end of the door 92 is a finger hole 9 for opening the door.
5 is provided.

For example, a thermostat 1 for detecting abnormal temperature rise is installed on the back of the heat shield plate 41 where it is easy to detect abnormal temperature rise of the container body 3.
01 is provided as a single unit, and even when the thermostat 101 detects an abnormal temperature rise by incorporating it into the electric circuit 73, the gas passage cutoff mechanism 5 is connected through the electric circuit 73.
8 to immediately stop the gas supply to the burner unit 21. Therefore, when an abnormal temperature rise occurs due to abnormal combustion, etc., the thermostat 101 can quickly detect it and cut off the gas supply to stop the combustion.
Thermal safety can be thoroughly measured.

The container body 3 has a handle 11 made of synthetic resin for carrying.
It is said to be convenient to carry as it has 1. The handle 111 has mounting arms 111b bent at right angles formed integrally with both ends of a horizontal grip portion 111a, and a mounting shaft 111c integrally formed on the inner surface of the end of each mounting arm 111b.
Utilizing the elasticity of 1, it is rotatably fitted on both sides of the side peripheral wall 3a of the container body 3, so that it can be freely folded down.

The handle 111 is a grip portion 111a when carried by hand.
is located at the top of the vessel body 3, and if left as is, it will be exposed to hot air during use and will easily suffer thermal deterioration. Therefore, the rotation of the handle 111 is restricted by a stopper 112 so that the handle 111 is normally tilted slightly backward as shown by the imaginary line in FIG. Incidentally, when the cassette cylinder 51 is loaded into the container body 3, the lower rear end of the container body 3 is lowered due to its own weight, so that the container body 3 can be maintained in an upright hand-held position.
If you let go of the handle 111 after carrying it in your hand, the handle 111 will naturally fall backwards and close to the group part 111a.
is arranged so that it automatically escapes from the upper part of the container body 3. Furthermore, if the handle 111 falls backward, depending on its position, the grip part 111a may enter the opening/closing path of the door 92 and obstruct the opening/closing operation, or it may hang over the ventilation hole 45 on the back of the container 3 and be exposed to the heat generated therefrom. Therefore, the handle 111 is adjusted to the tilted position using the stopper 113 as shown in FIG. It is regulated as follows.

Figure 8 shows handle 1 that includes such rotation restriction.
11 shows the structure of the pivot support 117. This shaft support 117 is made by elastically fitting a synthetic resin bushing 114 as shown in FIGS. The mounting shaft 111c of the handle 111 is fitted into the mounting hole 114a. At this time, even if the handle 111 is up and down, the mounting shaft 111c is prevented from coming into contact with metal parts and being damaged.
The stoppers 112, 113 are integrally formed on the handle 111, and the rotation can be restricted without damaging the handle 111 by contact with a protrusion 111d integrally formed on the inner surface of the mounting arm 111a of the handle 111. .

Each stopper 112, 113 is stabilized by fitting the bent portions 112a, 113a integrally formed at the tip into the hole 115 in the side peripheral wall 3a of the container body 3, and restricts the rotation of the handle 111 about the pivot support 117. We are making sure to do this.

The mounting shaft 111c is integrally formed with retaining pieces 111e at two locations in the diametrical direction.
Expansion notch 11 formed in the mounting hole 114a of No. 4
The mounting shaft 111c can be inserted into and removed from the mounting hole 114a only at the rotational position where the retaining piece 4b and the retaining piece 111e are aligned.

The grip portion 111a of the handle 111, which has fallen to the rear of the container body 3, protrudes somewhat from the back surface of the container body 3. Therefore, even if the container 3 is carelessly pressed against the wall of a room, a safe gap will always be left between the container 3 and the wall due to the protrusion of the grip portion 111a. This prevents the ventilation hole 45 on the back surface of the container body 3 from being blocked.

A cut-and-raised piece 121 is provided on a part of the heat shield plate 41, and even if an attempt is made to insert a spare gas cylinder 51 into the upright chamber 1, the cut-and-raised piece 12 obstructs the insertion of the spare gas cylinder 51 into the upright chamber 1.
This prevents the door 92 from being closed because it cannot be stored tightly. This prevents the danger of using the stove with the spare gas cylinder 51 stored.

(Effect of the invention) According to the invention, since it has the above-mentioned structure and operation, it is possible to open and close the lid of the gas cylinder inlet/outlet, to put in and take out the gas cylinder from the container, to exchange gas cylinders, and to change the gas cylinder stored in the container. Connecting to and opening the connection to a combustion appliance using an operating member can be carried out as is, without the appliance being turned over or upside down, and regardless of the rotational position of the handbag handle. It is convenient to use, and at the same time it can ensure thermal safety from the combustion part of the handbag handle.
