Description

[0001] Safety Valve Assembly of Gas Range [0002]

The present invention relates to a safety valve assembly for a gas range, and more particularly, to a safety valve assembly for a gas range, in which a central axis of a shaft and a central axis of a movable member for opening and closing an MPU are formed to be in contact with each other, To a safety valve assembly of a gas range capable of minimizing the loss when switching to a safety valve assembly.

A typical gas range is a cooking appliance that is used in modern kitchens and is a device that provides a heat source for users to cook using gas fuels such as liquefied natural gas (LNG) and liquefied propane gas (LPG).

Such a gas range is supplied with gas through a gas supply pipe from a separate storage container or reservoir where gas fuel is compressed and stored at a high pressure. However, since such a gaseous fuel may be dangerously explosive due to carelessness in use, various safety devices are indispensably required in the gas range in order to prevent this.

In addition to a valve for shutting off the gas in the gas supply pipe, a recent gas range is provided with an MPU (Magnet Power Unit) which can control the supply of gas depending on the situation.

Specifically, the MPU maintains the gas supply path opened by an electromotive force generated when heat is applied to the thermocouple of the gas range. When the heat is not applied to the thermocouple, the MPU shields the gas supply path, . Therefore, it is possible to prevent the gas from being continuously supplied in a state in which no flame is generated in the gas range.

Meanwhile, depending on the type and structure of the gas range, the direction of movement of the levers operated by the user may be different from that of the MPU. In this case, direction changing means for switching the movement of the lever to the driving direction of the MPU is provided.

However, in the related art, there is a problem that a loss occurs in the moving direction switching process because the axis of the lever direction of movement and the MPI driving direction axis are misaligned with each other. Accordingly, there is a problem that the direction changing means is twisted to cause deformation, and the MPU can not perform its function due to malfunction due to deformation.

Also, the structure of the housing for assembling the components is also complicated, and the housing is divided and assembled into a plurality of members, which complicates the molding and assembling process, resulting in a large reduction in yield and a frequent failure .

Therefore, a method for solving the above problems is required.

The moving part 34 is formed with a through hole 35 through which the insertion part 45b of the connecting member 45 passes.

The hinge part 32 extends forward of the moving part 34 and is hingedly connected to the body 10. Particularly, in this embodiment, the hinge portion 32 is rotatably connected to the extending protrusion 18 protruding upward from the body 10 by the rotating shaft member a. Accordingly, the movable conversion member 30 is rotatable about the rotation axis member a.

The pushing portion 36 extends to the rear lower side of the moving portion 34 and rotates about the axis of the hinge portion 30 in accordance with the downward movement of the moving portion 34 to move the moving member 54 Pressure.

4, the moving part 34 is pressed downward by the downward movement of the shaft 5, so that the entire movable shifting member 30 is pushed downward by the downward movement of the hinge 30 And is rotated about the axis. Therefore, the pressing portion 36 moves toward the moving member 54 and moves the moving member 54 forward.

In the foregoing, each component of the present invention has been described in detail, and the details thereof will be described below.

Specifically, the main body portion 12 accommodates the MPU 50 and the moving member 54 to be described later, and a main flow path 12a through which gas flows is formed.

The inlet 14 protrudes from one side of the main body 12 and communicates with the main passage 12a to form an inflow passage 14a through which gas flows.

The outflow portion 15 protrudes from the other side of the main body portion 12 and communicates with the main flow passage 12a to form an outflow channel 15a through which gas flows.

The connecting portion 13 is provided on the upper portion of the main body portion 12 and accommodates a plug 40 to be described later. The connecting passage 13a connects the main passage 12a and the outflow passage 15a. ).

As described above, in the present embodiment, the body 10 forms a flow path of gas connected to the inflow channel 14a, the main channel 12a, the connection channel 13a, and the outflow channel 15a, The gas can be delivered to the MPU 50 side before being transmitted to the plug 40 side.

The flow path of the gas is formed in the direction of the plug 40 from the MPU 50 so that even if the gas does not flow into the plug 40 but the MPU 50 after the flame of the gas range is extinguished, (50) side, and the safety can be greatly improved. This is because, in the case of the MPU 50, the path can be shielded by the sealing member formed of a material such as rubber, compared with the plug 40 which is formed as a whole.

Since the inlet 14 and the outlet 15 are formed on both sides of the main body 12 in which the MPU 50 is accommodated in this embodiment, the flow path of the gas can be simplified, So that it can be easily formed integrally. Therefore, the main body 10, the main body 12, the inflow portion 14, the outflow portion 15, and the connection portion 13 are integrally formed in the body 10 of the present embodiment.

As described above, one embodiment of the present invention has been described, and another embodiment of the present invention will be described below.

FIG. 7 is a side view of a safety switch assembly of a gas range according to another embodiment of the present invention. FIG. 8 is a side view of a safety switch assembly of a gas range according to another embodiment of the present invention. In which the vertical movement of the shaft 5 is converted into the forward and backward movement of the moving member 54. [

In the case of the other embodiments of the present invention shown in FIGS. 7 and 8, all the components are the same as those of the above-described embodiment, but the shape and the driving method of the movable switching member 130 are differently formed.

Specifically, in the present embodiment, the movement switching member 130 includes a moving unit 134 that moves downward in accordance with the downward movement of the shaft 5, and a moving unit 134 that extends toward the rear lower side of the moving unit 134, And a pressing portion 136 for pressing the moving member 54 downward in accordance with the downward movement of the portion 134.

In other words, the movable shifting member 130 of the present embodiment has a shape in which the hinge is omitted in comparison with the movable shifting member of the above-described embodiment, so that the entire movable shifting member 130 is not rotated but vertical Exercise.

More specifically, the moving part 134 of the movement switching member 130 is fixed to the connecting member 45 connected to the shaft 5, so that when the shaft 5 moves downward, The pressing portion 134 and the pressing portion 136 are moved downward together.

At this time, in the present embodiment, the pressing portion 136 is formed at a predetermined angle (?) Inclined rearward of the moving portion 134 to form an angle of at least a right angle with the moving portion 134.

Therefore, when the pressing portion 135 is downward, the pressing portion 135 is gradually moved closer to the moving member 54, so that the moving member 54 is pressed and moved forward.

In this case, the shape of the movable conversion member 130 can be diversified. In this case, however, the movable member 54 is formed so as to have a central axis that is in contact with the central axis of the shaft 5 So that it is possible to minimize the loss in the motion direction switching process.
