Using multiple members
The mainstream method is to build in a desktop type high-frequency heating device. Tabletop cookers require a space for the intake / exhaust of equipment due to the high temperature of the exterior used and
The width of the special box was limited to a module of only 60 cm. Therefore, when a function box such as a cooker or a dish drying cabinet is frequently provided under the hanging cabinet as in recent years, the 60 cm width of the built-in cooker poses a space problem. In addition, the width of the door of the hanging cabinet of the system kitchen is mainly 45 cm, and a cooker having a width of 60 cm has a problem in design. In the conventional method, since a dedicated box is attached and then built-in using members, there is a problem that the construction is complicated and it takes a long time.

[0003] Conventionally, a device such as a cooker or a dish-drying cabinet is usually installed under a hanging cabinet of a system kitchen, and then the installed wall is tile-finished. In the case of tile finishing, the tile attached to the periphery and the periphery of the installed equipment are jointed with cement etc., so the equipment is fixed to the wall and it is extremely difficult to remove it when repairing the equipment etc. There were many issues.

You are. The temperature rise of the exterior of the device due to the temperature rise of the heating chamber 11 is radiated to the surroundings.

[0007]

However, in this configuration, the tabletop type cooking device requires a space for taking in and exhausting the equipment due to the high temperature of the outer casing in use and the width of the exclusive box. Could only make a 60cm module. Therefore, when a function box such as a cooker or a dish drying cabinet is frequently provided under the hanging cabinet as in recent years, the 60 cm width of the built-in cooker poses a space problem. In addition, the width of the door of the hanging cabinet of the system kitchen is mainly 45 cm, and a cooker having a width of 60 cm has a problem in design. In addition, in the conventional method, since it is built in using the member after attaching the special box,
There were problems such as complicated construction and long time. or,
2.

[0031]

As described above, the following effects can be obtained in the built-in type high frequency heating apparatus of the present invention.

(1) By providing a ventilation passage structure that is continuous with the rear wall surface and the upper wall surface of the heating chamber, and that the ventilation from the ventilation device flows to an exhaust port provided in the upper part of the heating chamber, it is possible to form an outer casing of the equipment. The temperature rise can be suppressed, and it can be installed in close contact with a kitchen wall or a cabinet without a dedicated box or other members. This makes it easy to perform the work under the hanging cabinet in a short time.

(2) The blower of the blower is divided into two
By blowing air to the netron and the inverter power supply unit, it is possible to economically cool with one motor, and the width of the equipment can be easily reduced to 45 cm or less.

(3) A ventilation path configuration communicating with the exhaust port is provided between the rear surface and the wall surface of the device, and a power supply connection unit with the indoor wiring is accommodated in the ventilation path configuration section. The reliability in terms of safety can be secured without raising the ambient temperature. Also, after the equipment is installed, the beauty of the system kitchen can be achieved by making the power cable and the like invisible.

(4) The position of the suction port of the blower and the position of the suction port provided on the bottom surface of the exterior are shifted without facing each other, and a suction air passage is provided between the suction port and the suction port to thereby take in air. By the time the outside air such as steam sucked from the mouth passes through the intake air passage and reaches the suction port of the blower , some steam is condensed on the wall of the intake air passage, which has an effect of reducing the amount of intrusion into the blower. .

(5) By providing a ventilation resistor which is bent in a concave shape in the intake ventilation path facing the intake port,
Vapors, dust, etc. sucked from the air inlet are attached to the ventilation resistor to reduce the amount of air entering the blower . In order to enhance the adhesion effect, the ventilation resistor is made concave to provide a plurality of filter effects.

[0037] (6) the upper surface of the air blowing port of the blower long as pop than the lower surface, bending the tip of the upper face, by providing the porous body, water droplets condensed on the blower is the blower opening It is prevented from being scattered to the inverter power supply along the upper surface, which prevents the insulation of the equipment from deteriorating.
By providing a shield plate that covers a part of the inverter power supply, it is possible to prevent water droplets dropped on the shield plate from dropping on the inverter power supply, thereby preventing the insulation of the equipment from deteriorating. Thus, there is an effect that the failure of the device is prevented and the reliability is secured against the invasion of steam or steam entering the device.

(7) As a part of the exterior side plate,
By installing a detachable spacer on the back, after the main unit is installed under the hanging cabinet, the kitchen wall is generally tiled. The portion to be bonded by the joint finish for filling the gap becomes the spacer portion, and when the device is removed, the main body and the spacer portion can be separated, so that the device can be easily removed.

(8) The spacer is provided with two projections on the right and left, and a through hole is provided on the facing exterior side plate, so that the spacer can be attached to the main body and remounted after the appliance has been removed from the kitchen. The projections serve as guides for easy positioning and secure mounting.

(9) Insert the protrusion of the spacer into the through hole of the exterior side plate, and slide the spacer downward.
By forming the protrusion of the spacer to be joined to the exterior side plate, the spacer can be easily fixed to the main body without any member such as a screw at the time of attachment.

(10) After installing the main body under the hanging cabinet, when the main body is removed, even if the spacer is adhered and fixed to the kitchen wall, if the screw fixing the rail is loosened, the main body falls and the protrusion of the spacer is lowered. With the configuration in which the portion is disconnected from the exterior side plate, the device body can be easily removed.

(11) Since the spacer itself is fixed to the kitchen wall by performing a treatment having adhesiveness or tackiness on the back surface of the spacer, a dish drying cabinet or the like is installed adjacent to the equipment body. Even if one side is not bonded by joint finishing, it is securely fixed to the kitchen wall, and when the detached device body is re-attached, it can be securely attached without changing its position.
