Description

{A mounting structure of a door for microwave oven}

The present invention relates to a microwave oven, and more particularly, to a door assembly structure of a microwave oven, which maintains a uniform gap between a door fixed to one end of a front panel and a control panel to improve the appearance of the product. It is about.

In general, microwaves oscillate from a magnetron (high frequency of 2450MHz) is irradiated to food (dielectric), and the molecules of food are actively collided with each other according to the frequency of the irradiated microwaves. Dielectric heating is used to heat and cook by heating.

That is, as the polarity of the electric field is converted in the state where the food is placed in the electric field, the arrangement of the molecules in the electric equilibrium state is changed according to the change in the frequency polarity, thereby causing the molecules to friction and generate heat.

As shown in FIG. 1, the microwave oven is formed by an outer panel 20, a front panel 30, and a back panel (not shown) surrounding the outside of the cavity 10. A cavity 10 is partitioned into a cooking chamber A, which is a space for heating and cooking food, and a machine room B, which is a space in which various electric parts of a microwave oven are mounted.

Here, the mechanical chamber (B) is provided with a magnetron for generating microwaves (not shown), a waveguide for guiding microwaves into the cooking chamber (A), and electrical components such as a high voltage transformer for supplying power to the magnetron. The front surface of the (B) is provided with an operation unit (C) for setting the operation control and cooking time and cooking conditions according to the food, and the control panel 40 covering the operation unit (C) to the front panel 30 It is stuck.

In addition, a tray 50 is seated on the bottom side of the cooking chamber A to allow food and cooking containers to be cooked therein.

Therefore, the microwave oven configured as described above operates the operation unit C in a state in which the user seats a cooking container containing food or food to be cooked in the tray 50 for cooking, thereby controlling cooking time and cooking conditions. After setting, when the power is turned on, microwaves are emitted from the magnetron and microwaves are irradiated to the cooking chamber A according to the guide of the waveguide, and the irradiated microwaves are seated on the tray 50 in the cooking chamber A. By irradiating the food evenly, the food is heated and cooked.

On the other hand, in the above, the door 60 for opening and closing the opening of the cooking chamber (A) is fixed to one side of the front panel 30, the control panel 40 and a constant gap (GAP) on the front of the cooking chamber (A). It is assembled to have.

However, in assembling the door 60 so that the gap between the door 60 and the control panel 40 is uniform in order to improve the appearance of the product in the related art, the door 60, as shown in FIG. And assembling using a jig 70 having the same thickness as the width a of the gap so that the gap between the control panel 40 and the control panel 40 is uniform. There was a problem.

Accordingly, the present invention is to solve the above problems, an object of the present invention to improve the appearance of the product by maintaining a uniform gap (GAP) between the door and the control panel without using a jig. In addition, to provide a door assembly structure of the microwave oven to improve the assembly productivity.

In order to achieve the above object, the present invention provides a door assembly structure of a microwave oven in which a door for opening and closing an opening of a cooking compartment is fixed to one side of a front panel and assembled to have a predetermined gap with a control panel. A plurality of spacers are formed between the door and the control panel to serve as a jig to uniformly maintain the gap between the door and the control panel.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a perspective view showing a state where the spacer is provided with a projection according to the present invention, Figure 4 is a perspective view showing a state in which the door with a spacer is assembled and closed according to the invention, Figure 5 is a part of Figure 4 As a plan view, it shows a state where the spacer is in contact with the door and the control panel.

In the drawings, the same components as those in the related art are denoted by the same names and the same reference numerals, and detailed description thereof will be omitted.

As shown in FIG. 3, a cavity is formed into a cooking chamber A, which is a space in which food is heated and cooked by the cavity 10, and a machine room B, which is a space in which various electric components of a microwave oven are mounted. The exterior is formed by the outer panel 20 and the front panel 30 surrounding the outside of the cavity 10, the tray 50 for seating and cooking food is seated in the cooking chamber A, The front surface of the machine room B is provided with an operation unit C for setting food cooking time and cooking conditions, and a control panel 40 covering the operation unit C is fixed to the front panel 30. .

Of course, the machine room (B) is provided with electrical components such as magnetron, waveguide, and high voltage transformer (not shown).

In this case, the door 60 is hinged to the front panel 30 of the cooking chamber A. When the door 60 is assembled to one end of the front panel 30, the door 60 and the control panel are assembled. A plurality of spacing protrusions 1 are formed on one side of the door 60 to support the gap between the 40.

Here, the spacer protrusion 1 may be formed on one side of the control panel 40 without being limited to the one side of the door 60.

That is, the spacer protrusion 1 serves as a jig to uniformly maintain the upper and lower gaps between the door 60 and the control panel 40 at the time of assembling the door 60. What is necessary is to be located between the control panel 40.

Therefore, when the spaced protrusion 1 is used at the time of assembling the door 60 as described above, the trouble of matching the gap between the door 60 and the control panel 40 by using the conventional jig 70 is eliminated. However, the gap between the door 60 and the control panel 30 can be maintained uniformly, thereby improving the assembly of the door 60 and thus improving the productivity and appearance of the product.

As described above, according to the present invention, the spacer is formed to be located between the door and the control panel to maintain the gap between the door and the control panel while the spacer is acting as a jig when assembling the door, jig at the time of door assembly As it is not necessary to use, assembling is facilitated, productivity is improved, and the gap between the door and the control panel can be maintained uniformly, thereby improving the appearance quality of the product.
