Description

Power supply for microwave ovens with a hood {Power supply device for ventillation hooded microwave oven}

The present invention relates to a microwave oven for hood, and more particularly, when the power cord is detachably configured from the main body of the microwave oven, the microwave oven is configured so that a current can be applied only when the power cord is completely coupled to the microwave oven. Relates to a power supply unit.

The hood-use microwave oven is installed on the upper portion of the gas oven range and has a function of exhausting heat or smoke generated from the gas oven range. FIG. 1 shows a state where a conventional hood-use microwave oven (hereinafter, simply referred to as a microwave oven) is installed. In general, the hood-use microwave oven is installed on the wall surface W at a position corresponding to the upper portion of the gas oven range. That is, the mounting plate 2 is first mounted on the wall surface W, and the main body of the microwave oven is rotated in the direction of the arrow while the lower end of the rear surface of the microwave oven main body 4 for hood is fastened to the mounting plate. After that, the microwave will be completely fixed.

At this time, the cabinet 6 for accommodating the various goods required by a kitchen is provided in the upper part of the said food and microwave oven. Then, the power cord 10 for applying a current to the microwave oven is led out through the mounting hole 8 formed in the bottom surface of the cabinet 6 and then electrically connected to the power source.

In the conventional hood-use microwave oven, since the power cord 10 is integrally assembled to the main body 4 as shown in the figure, the microwave oven is installed directly under the cabinet 6 as described above. In case, the hassle is raised. That is, after supporting the main body 4 to the bottom surface of the mounting plate 2, the power cord 10 should be pulled out through the mounting hole 8 while rotating the main body in the direction of the arrow. Since these two operations must be performed at the same time, it is a reality that the operation of mounting the microwave oven body on the wall surface W is quite difficult and at the same time dangerous.

It is understood that the inconvenience caused when the conventional hood-only microwave oven is mounted is due to the fact that a power cord for applying a current to the microwave oven is integrated in the main body 4 of the microwave oven.

In order to solve the conventional problems as described above, it may be proposed to separate the main body and the power cord of the hood and microwave oven. This will be described based on FIG. 2. As can be seen with reference to Figure 2, according to the present invention, the power cord 30 is configured to be detachable to the main body 20 of the microwave oven. That is, as shown, the power cord 30 is configured to be released in a state separated from the main body 20 of the microwave oven, the inlet (Inlet) socket on the upper portion of the main body 20 of the microwave oven Install (22). The power cord plug 32 provided at one end of the power cord 30 is inserted into the inlet socket 22. Therefore, by inserting the power cord plug 32 into the inlet socket 22, the power cord 30 and the main body 20 of the microwave oven can be electrically connected. And the other side of the power cord 30 is provided with a plug portion 34 that is connected to the normal power plug, it is possible to connect to the power using this plug portion 34. When using the separate power cord 30 as described above, the hood-only microwave oven is completely installed on the wall, and then the power cord 30 is connected to the inlet socket 22 of the microwave oven through the mounting hole of the cabinet. . Therefore, the inconvenience of the power cord can be completely eliminated when installing a hood and microwave oven. 3 is a cross-sectional view of connecting to the main body using the power cord 30 is shown. As shown in the figure, when the power cord plug 32 is inserted into the inlet socket 22, the terminals 22a and 32a provided therein are electrically connected to each other. Current can be supplied to the range.

However, when the power cord 30 and the inlet socket 22 are coupled to each other, if the plug 32 of the power cord 30 is not completely coupled to the inlet socket 22, the heat of resistance may be caused by incomplete electrical connection. This may cause an increase in the risk of fire. In particular, in consideration of the high rated current value used in the microwave oven, the electrical problem caused by such an incomplete connection is a safety problem.

An object of the present invention is to configure the power cord of the microwave oven with a hood, so that the current is not supplied unless the power cord is completely combined with the inlet socket, the problem of stability due to incomplete electrical connection It is to be solved.
