Abstract

PURPOSE:To decrease assembly time and to enable simplification of mounting and demounting, by providing a suspension tool, secured in parallel to a ceiling surface and provided in a central part with large and small oblong holes, a hook, having a tip bent downward, and a resilient body, exerting a resilient force on a ceiling surface and a grill burner. CONSTITUTION:Mounting of a grill burner 6 is such that a throat part 6a of the grill burner 6 is inserted in a hole 8 of a grill case 5 to support the one side, and the projecting part 4a of a hook 4 is coincided to a position right below a hole 2. The projecting part 4a is inserted from the under side into the hole 2, and by moving the projecting part 4a until the projecting part is collided with the edge of the hole 2, a tip 4c of the projecting part 4a is positioned right above a hole 3. With the grill burner 6 released from a hand, the grill burner is pressed down through the repulsion force of the resilient body 7, and the tip 4c of the projecting part 4a is engaged with the hole 3. The grill burner 6 may be demounted by reversing the mounting procedures. Regulation of longitudinal and horizontal movement is effected by the hole 3 and the tip 4c, and regulation of vertical movement is effected by the resilient body. This constitution enables mounting and demounting of the grill burner through a single hand, decreases assembly time, eliminates the need to disassemble a device for mounting and demounting, and provides excellent maintainability.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to improving the ease of attaching and detaching grill burners of household gas appliances: Fixing grill burners that can improve efficiency during mass production and ease of maintenance during repair. It is related to the device.

Conventional technology To fix the grill burner of current household gas appliances, a part of the fixing device of a sheet metal piece that is provided on the top surface of the grill burner and has a hole in the end surface bent perpendicular to the grill burner is drilled in the ceiling surface of the grill case. A method that is often adopted is to fix a grill burner in a grill case by passing a wire through a slit-like rectangular hole and passing a wire through the hole of the fixing device.

An example of a conventional grill burner fixing device will be described below with reference to the drawings.

Figure 4a shows a grill burner with a grill case and a fixture attached, 9 is a fixture, both ends 9a of which are bent perpendicularly to the grill burner 6, each having a hole 9b at its tip, and a base. 9c is fixed to the center of the upper surface of the grill burner 3. Further, in the side wall 5b of the grill case 5, there is a hole 1o through which the burner throat portion 6a can pass and both ends 9a of the fixture 9 pass.
There are two rectangular shapes on the ceiling surface 5a. FIG. 4 shows the grill burner 6 fixed inside the grill case 6. After passing the burner throw 8a through the hole 8 from inside the grill case 5, both ends 9a of the fixture 9 are passed through the hole 10. ,
A method is used in which the hole 9b is exposed above the ceiling surface 5a of the grill case 5 and the wire rod 11 is passed through the hole 9b to fix the grill burner 6.

Problems to be Solved by the Invention However, with the above configuration, when assembling, the operator has to support the grill burner 6 with one hand in order to expose the holes 9b at both ends 9a of the fixture 9 above the ceiling surface 5a of the grill case 5. In this state, the wire rod 11 is inserted with the other hand, resulting in poor work efficiency. In addition, in order to attach and detach the grill burner 3 during inspection and repair, it is necessary to disassemble the appliance to a state where the wire rod 11 can be attached and detached, resulting in a problem of poor maintainability.

The present invention solves these problems and provides a grill burner fixing device for household gas appliances that reduces assembly time, has a simple structure, can be attached and detached by anyone, and is reliable.

Means for Solving the Problems The grill burner fixing device of the present invention has both ends provided on the ceiling surface inside the grill case, and two large and small parallel pieces, parallel to the ceiling surface and extending downward and spaced apart at a certain distance, in the center. A hanger with a rectangular hole and a protrusion that is smaller than the large hole of the hanger, and its tip is parallel to the grill ceiling surface and fits between the two large and small holes of the hanger. a hook having a length slightly larger than the distance between the two and whose leading edge is bent downward to a thickness greater than the thickness of the hanging device, and fixed to a part of the hook or to the inner ceiling surface of the grill case;
Both ends are bent toward the inner ceiling surface of the grill case or toward the fixing device 1, and the vicinity of the tip is inclined toward the outside and has an elastic body such as a leaf spring that applies elastic force to the inner ceiling surface of the grill case or the grill burner. It is.

Function: With this configuration, the grill burner can be attached and detached easily and reliably by a series of movements using one hand, and there is no need to disassemble the appliance body for attaching and detaching the grill burner.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

(1) is a U-shaped hanging fixture with both ends fixed to the center of the inner surface of the ceiling surface 5a of the grill case 5, and is separated from the ceiling surface by a certain distance and has two parallel rectangles in the parallel center. A hole 2.3 is formed.

4 is a hook fixed to the center of the upper surface of the grill burner 6;
It has a protrusion 4a smaller than the large hole 2 of the hanging tool 1, and its tip 4b is parallel to the ceiling surface 5a inside the grill case and slightly smaller than the distance between the two large and small holes 2.3 of the hanging tool 1. It has a large length, and the leading edge 4c is bent downward to a thickness greater than the thickness of the hanging tool 1. 7 is an elastic body such as a leaf spring fixed to the base of the hook 4, with both ends 7a bent upward;
The vicinity of the tip thereof has a shape that is inclined outward, and this tip abuts against the ceiling surface 5a of the grill case 5 to apply elastic force between the grill case 5 and the grill burner 6. B is a hole formed in the side wall 5b of the grill case 5, through which the grill burner 6 is inserted.
Insert and support the throat part 6a. The operation will be explained below. To install the grill burner 6, first insert the throat part 6a of the grill burner 6 into the hole 8 with one hand to support one side, and then attach the protruding part 4 of the hook 4 as shown in FIG.
Align a directly below hole 2. Next, hole 2 as shown in Figure 3.
Insert the protrusion 4a from below, and then
When the protrusion 4a is moved in the direction of the arrow until it touches the edge of the hole 2, the tip 4c of the protrusion 4a is located directly above the hole 3. After that, remove your hand from the grill burner 6 and the elastic body 7
is pushed down by the elastic force generated when it comes into contact with the ceiling surface 5a of the grill case 5, and the tip 4c of the protrusion 4a
is engaged with the hole 3 as shown in FIG. 3d. The grill burner 6 can be removed in the opposite order to the above-described installation order.

In this way, the movement of the grill burner in the front, back, left and right directions is controlled by the hole 3 and the tip 4c, and the movement in the vertical direction is controlled by the elastic body.

Note that even if the hanging tool 1 may be formed directly on the ceiling surface 5a of the grill case 5, or the elastic body 7 may be fixed on the ceiling surface 5a side of the grill case 5, the above-mentioned effects will be the same.

Effects of the Invention As described above, in the present invention, the grill burner can be attached and detached with a series of one-handed movements, reducing assembly time, and there is no need to disassemble the appliance for attaching and detaching the grill burner, resulting in excellent maintainability.
