Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a wall-mounted microwave oven, and particularly relates to its mounting angle adjustment mechanism.

(b) Prior Art Microwave ovens are heavy, so when the back plate is fixed to a wall, the top often tilts forward due to its own weight. Also, since high-temperature foods are handled, the slope poses a safety problem. Conventionally, the structure to prevent this tilting was to lower bolts from the ceiling and hang the microwave oven from the bolts, but this had the disadvantage that the bolts were exposed, making it unsightly, and the work of hanging the microwave oven was also very time-consuming. It was heavy. Furthermore, in the past,
There were some models that tilted the back surface, which is the mounting surface of the microwave oven, to prevent it from tilting due to its own weight, but this model is fully effective because the inclination changes depending on the wall condition and mounting conditions. It wasn't.

(c) Purpose The invention was made in view of the above circumstances, and aims to provide a wall-mounted microwave oven that is simple and inexpensive, and is equipped with a mounting angle adjustment mechanism that is invisible from the outside.

(D) Structure In this invention, a hexagonal flange nut is incorporated into the lower part of the back of the microwave oven, and its more detailed structure includes a wall attachment part provided at the upper part of the back plate of the equipment box. A part of the oven component panel is overlapped and fixed to the lower inner surface of the back plate, and a space is provided between the overlapped parts, and the part where the space is located is attached to the opposing back plate and oven component panel. , a bolt end protrusion hole and a nut part insertion hole having a structure for preventing rotation of the nut part are respectively provided, and the base part is housed in the space, and the nut part is inserted into the insertion hole of the nut part to form a hexagonal flange nut. There is a wall-mounted microwave oven in which an angle-adjusting bolt is screwed into the nut portion of the hexagonal flange nut such that its end protrudes outward from the bolt end protrusion hole.

(e) Examples Examples of this invention will be described below in detail with reference to the drawings, but this invention is not limited to the following examples.

FIG. 1 shows the wall-mounted microwave oven 1 of this invention attached to a wall 2, FIG. 2 shows the bottom of the microwave 1, and FIG. 3 shows the microwave oven 1 with the bottom plate 3 removed. 4 is a mounting plate separate from the microwave oven 1, and this mounting plate 4
is used as a reinforcing member when the wall surface 2 to which it is attached has low strength, such as a plasterboard, and a receiving portion 5 is provided at the bottom to facilitate the installation work of the microwave oven 1. An oven 7 is constructed within the equipment box 6 of the microwave oven 1, and 8 is a panel for configuring the oven 7. As shown in FIG. 4, the lower part of this panel 8 is bent and overlapped with the inner lower part of the back plate 9 constituting the equipment box 6, and is fixed with screws 10. Hexagonal flange nuts 11 are attached to two locations in the overlapped portion. Bolt end protrusion holes 1 are provided at opposing positions between the back plate 9 and the panel 8.
2 and a rectangular nut part fitting hole 13 are provided, and the peripheral edge of the protruding hole 12 of the back plate 9 is configured to protrude outward by caulking, so that the protruding hole 12 and the fitting hole 13 are A space 14 exists between the overlapping parts at opposing positions. The base portion 15 is housed in this space 14, and the nut portion 16 is inserted into the insertion hole 1.
A hexagonal flange nut 11 is attached in a state where it fits into the inside of the hexagonal flange nut 11. As shown in FIG. 5, the insertion hole 13 is square as described above, and its width is similar to that of the nut portion 16 of the hexagonal flange nut 11.
Since the width is slightly wider than the width of the nut part 1.
This prevents the rotation of hexagonal flange nut 1.
1 is attached in a substantially fixed state. This 6
An angle adjusting bolt 17 is screwed into the nut portion 16 of the square flange nut 11, and its end portion projects outward from the projecting hole 12.

The angle adjustment operation of the microwave oven 1 using the angle adjustment bolt 17 will be explained below, but before that, the mounting structure of the microwave oven 1 on the wall surface 2 will be explained.

First, the mounting plate 4 is attached to the wall surface 2 at a predetermined position with bolts, but in reality, the bolts are fixed to columnar bodies called studs located at predetermined positions on the back surface of the wall surface 2. The microwave oven 1 is attached to the attachment plate 4 attached in this way at the upper part of the back plate 9. This attachment can be done with screws or with a hook mechanism. When it is done with screws, a screw hole is made, and when it is done with a hook mechanism, the hook member is attached to the top of the back plate 9. It is provided as a mounting part (not shown). During this installation, if the lower edge of the overlapping portion of the back plate 9 and panel 8 is placed on the lower receiving portion 5 of the mounting plate 4, this work can be easily performed.

A bottom plate 3 is normally attached to the microwave oven 1. To adjust the angle, first remove the bottom plate 3. Then, screw in the bolt 17 for adjusting the angle. Due to this screwing, the end of the bolt 17 protrudes outward and pushes the mounting plate 4, but since the mounting plate 4 is supported by the wall 2 and maintains a fixed position, the hexagonal flange nut 11 is relatively fixed. Mounting plate 4
It becomes a state of moving away from. As a result, microwave oven 1
The lower part protrudes slightly forward to adjust the angle.

This idea incorporates a hexagonal flange nut between the back plate and panel at the bottom of the back of the microwave oven, but the overlapping structure of the back plate and panel was originally provided as a reinforcement structure for the device. Using that part, a hexagonal flange nut was attached without welding.

(f) Effects This idea is structured as described above, so
The mounting angle can be easily adjusted by removing the bottom plate and using the angle adjustment bolts. Furthermore, since the overlapping portion of the back plate and the panel is used to attach a commercially available hexagonal flange nut, the construction is simple and advantageous in terms of manufacturing and cost. Furthermore, since the angle adjustment bolts and hexagonal flange nuts are normally hidden in the bottom plate of the device, they look good.
