Description

[Detailed Description of the Invention] This invention relates to a wall-mounted microwave oven and aims to facilitate maintenance and inspection of the microwave oven main body housed in an outer case.

Conventionally, a wall-mounted microwave oven is constructed as shown in FIGS.
is inserted and stored in the exterior case 2 through its front opening. When the microwave oven main body 3 is inserted into the outer case 2, a wind tunnel 4 is formed between the microwave oven main body 3 and an air intake port 5 and an indoor grill 6 formed on the lower and upper front surfaces of the outer case 2.
are connected to the wind tunnel 4, respectively, and an exhaust duct 7 to the outdoors above the exterior case 2 is provided to communicate with the wind tunnel 4. And outer case 2
When the fan 8 installed in the microwave oven is driven, the air taken in from the intake port 5 passes through the wind tunnel 4 and is discharged from the exhaust duct 7 or indoor grill 6 along with the smoke, heat, or odor generated from the microwave oven body 3. Here, switching between the exhaust duct 7 and the indoor grill 6 is performed by a flapper-shaped switching valve 9. Further, an electrical component storage section 11 is formed on the right side of the microwave oven body 3, that is, behind the control panel 10, and the storage section 11 includes a high-voltage transformer 12, a high-voltage capacitor 13, magnetron 14,
A blower motor 15 and the like are stored in this storage section 11.
is closed by a side plate 16 to protect various electrical components inside from heat, dust, etc. Note that the side plate 16 is attached to the microwave oven body 3 using 7 to 9 screws 17 in order to prevent chattering noise.
is fixed to the right side of the

By the way, in this type of microwave oven, it is necessary to remove the side plate 16 from the microwave oven main body 3 during maintenance and inspection of the microwave oven main body 3, but according to the conventional microwave oven,
Since the side plate 16 is fixed with screws 17 around its entire circumference, it is necessary to pull out the microwave oven body 3 from the outer case 2 in the direction of the bold arrow, that is, forward, and then remove the side plate 16, which is extremely labor-intensive. Furthermore, since the microwave oven body 3 normally weighs around 30 kg, it requires a large number of people to pull out the drawer, making service more difficult.

This invention was made with the above points in mind, and in a microwave oven in which the microwave oven main body is housed in an exterior case fixed to a wall, a flange extending rearward is formed on the rear surface of the microwave oven main body. At the same time, a U-shaped folded part is formed on the rear edge of the side plate of the microwave oven main body to be engaged with the flange, and the folded part of the side plate is engaged with the flange, and substantially the front half of the side plate is formed. This is a microwave oven in which the microwave oven is screwed to the microwave oven main body.

Therefore, during services such as maintenance and inspection,
The side plate can be easily removed by simply pulling out almost the front half of the microwave oven from the outer case, removing the screws on the side plate, moving the side plate slightly backwards, and pulling out the folded part from the flange. There is no need to remove the microwave oven body from the outer case, and there is no need for multiple people.
The service can be performed easily and easily.

Next, this idea will be described in the fourth section showing one example of it.
This will be explained with reference to the drawings below.

In these drawings, the same symbols as above indicate the same parts, 18 is a flange formed by bending the right edge of the rear plate of the microwave oven main body 3 at a right angle rearward, and 19 is a flange formed on the right side of the microwave oven main body 3. Side plate 16'
U-shaped planar folded portions 20 and 21 formed by folding back the rear edge from the inside to the front and secured to the flange 18 are formed on the rear side edge by folding the rear side edge forward from the inside, and the folded portions 20 and 21 respectively extend from the upper and lower side edges and the front side edge of the side plate 16'. These are bent pieces formed by bending at right angles, and the rigidity of the side plate 16' is improved by each bent piece 20, 21. 22 is side plate 1
There are three screw holes provided on the outer periphery of the front half of the microwave oven 6'. By fastening the side plate 16' to the right side surface of the microwave oven main body 3, the side plate 16' is securely and firmly fixed to the right side surface of the microwave oven main body 3, thereby preventing the generation of chattering noise.

Therefore, according to the embodiment, when servicing the microwave oven main body 3, such as maintenance or inspection, the microwave oven main body 3 is pulled out approximately half forward from the outer case 2, and the three screws 17 for fixing the side plate 16' are removed. After removal, the side plate 16' can be removed by pushing only the side plate 16' backward and pulling out the folded part 19 from the flange 18, so there is no need to take out the whole microwave oven body 3, and there is no need to remove the side plate 16'. There is no need for multiple people to carry out the pull-out operation; one person is sufficient, and since the side plate 16' can be fixed with only three screws 17, the side plate 16' can be quickly attached and removed.
Workability is improved, and services such as maintenance and inspection can be performed easily and easily.
