Description

[Detailed Description of the Invention] (a) Purpose of the Invention [Field of Industrial Application] This invention relates to a wall-mounted microwave oven, and more specifically to a wall-mounted microwave oven with an improved wall-mounting structure.

[Conventional technology]

Generally, a wall-mounted microwave oven has a main body 3 attached to a mounting plate 2 fixed to a wall 1, as shown in FIG.
The microwave oven body 3 is attached to the mounting plate 2 by hooking the lower end thereof and pressing the microwave oven body 3 in the direction of the arrow.

In this microwave oven, as shown in FIG. This is done by a pair of locking levers 8, 8 which are movably attached to the inner surface of the main body 3 of the rear plate 5 by means of an E-ring 6 and a lever pin 7 along that surface. Specifically, as shown in FIG. 6, the bridge-like protrusion 4 is inserted into the microwave oven main body 3 through the openings 9, 9 provided in the rear plate 5, and the bridge-like protrusion 4 is inserted into the microwave oven body 3. The upper end of the lock lever 8 is inserted into the space 10, and after this insertion, the lower end of the lock lever 8 is fixed to the rear plate 5 with screws 11, and the microwave oven body 3 is fixed to the mounting plate 2.

[Problem that the invention attempts to solve]

However, with the above mounting structure, if the pressing force in the direction of the arrow shown in FIG. 4 is insufficient, the bridge-like space 10 as shown in FIG. 6 is not formed within the main body 3. When the lock lever 8 is moved as shown in FIG. Therefore, the microwave oven body 3 is the mounting plate 2.
One is that the lock lever 8 is inserted into the bridge-like space 10 because the lock lever 8 moves, although the lock lever 8 is not fixed, that is, the lock lever 8 is in a locked state.
There was a risk of being judged incorrectly.

This idea was made in view of the above circumstances,
Its main purpose is to prevent the lock lever from moving with the rear plate if the pressure on the mounting plate of the microwave oven is insufficient, so that the lock lever can only move when the pressure is applied sufficiently. The purpose is to prevent the installer from mistakenly determining that the device is in a locked state.

(b) Structure of the device This device inserts one or more bridge-like protrusions protruding from a mounting plate fixed to a wall into the main body through an opening provided in the rear plate of the microwave oven main body, and In a wall-mounted microwave oven in which the main body is attached to the mounting plate by engaging a locking lever rotatably attached to the rear plate of the main body with a pin in the bridge-like space of the bridge-like projection, the locking lever is A coil spring is wound around the outer circumference of the pin to bias the locking lever toward the inner side of the rear plate's body, and the locking lever is supported so that it can move in the axial direction of the pin. The mounting plate includes a locking protrusion that locks movement, and a push-up protrusion that protrudes into the main body from a through hole provided in the rear plate and pushes the locking lever past the top of the protrusion when the main body is pressed against the mounting plate. This is a wall-mounted microwave oven.

〔Example〕

This invention will be explained in detail below based on the embodiments shown in the figures. Note that this invention is not limited to this.

FIG. 1 is a perspective view of a main part of a wall-mounted microwave oven 12, and FIG. 2 is an enlarged view thereof. Note that the same reference numerals are given to the same components as in the prior art, and the description thereof will be omitted.

A pair of locking protrusions 13, 13 for locking the movement of the lock lever 8 are provided on the inner surface of the microwave oven body 3 closer to the corner than the opening 9 of the rear plate 5. A pair of through holes 14, 14 are provided between the locking projection and the opening 9.

On the other hand, in the mounting plate 2, when the bridge-like protrusion 4 of the mounting plate is engaged with the opening 9 of the rear plate, the through hole 14
A pair of pressing protrusions 15, 15 are provided which engage with each other. A coil spring 16 is inserted into the lever pin 7 and biases the lock lever 8 against the inner surface of the main body 3 of the rear plate 5.

Next, the attachment of the microwave oven main body 3 to the wall will be explained.

First, the rear plate 5 is hooked onto the mounting plate 2 by engaging the opening 9 of the rear plate 5 with the bridge-like protrusion 4 of the mounting plate 2 fixed to the wall 1 as in the conventional case. At this time, when the lock lever 8 attempts to move toward the bridge-like projection 4, it comes into contact with the side surface of the locking projection 13 on the rear plate opening 9 side, as shown in FIG. Ru. Next, when the microwave oven body 3 is further pressed, the second
As shown in the figure and FIG. 3B, the push-up projection 15 of the mounting plate 2 comes into contact with the lock lever 8 and pushes the lock lever 8 up from the rear plate 5 surface over the top of the locking projection 13. When the lock lever 8 is moved in the direction of the arrow in FIG. 2, the lock lever 8 passes over the locking projection 13 and is inserted into the bridge-like space 10 of the bridge-like projection 4 projecting from the rear plate 5.

In this way, the microwave oven main body 3 can be fixed to the mounting plate 2. Therefore, if the pressure on the mounting plate 2 of the microwave oven main body 3 is not sufficient, the movement of the lock lever 8 will be stopped as shown in Fig. 3a, and the installer may mistakenly judge that the microwave oven is in the locked state. disappears.

Note that the number of locking projections 13 and push-up projections 15 is not limited to one pair, and they are provided in correspondence to the number of lock levers 8.

(c) Effect of the invention This invention provides a locking protrusion that locks the movement of the locking lever on the rear plate of the microwave oven body, and when the microwave oven body is pressed against the mounting plate, the locking lever locks. Since the mounting plate is equipped with a push-up protrusion that pushes the locking lever up over the top of the protrusion, if the microwave oven body is not pressed sufficiently against the mounting plate, the locking lever will come into contact with the locking protrusion. This prevents the bone from moving toward the bridge protruding from the posterior plate.
Thereby, it is possible to prevent an erroneous determination that the locking lever has been inserted into the bridge-like space of the bridge-like projection.
