The present invention relates to a microwave oven, and more particularly to a lamp holder for supporting a lamp that illuminates the inside of the cavity of the microwave oven.

In general, a microwave oven (MWO) is a device for cooking food by the heat of intermolecular friction generated by disturbing the molecular arrangement of food by using a high frequency (about 2,450 MHz per second) as a heating source.

As shown in FIG. 1, the microwave oven includes a main body 10 including a front case 11 and an outer case 12, an exterior frame 13, and a cavity 20 forming a cooking chamber. And an electrical equipment room 30 in which various electrical equipment parts are installed.

In this case, the front case 11 forms the front surface of the main body 10, and is provided with a cavity door 14 for opening and closing the cavity 20.

In addition, the exterior frame 13 forms the bottom and the rear of the main body 10 and together with the outer case 12 and the front case 11 to protect the cavity 20 and the electric compartment 30 from an external environment. do.

The electrical component is a magnetron 31 that generates microwaves, a high voltage transformer 32 that supplies a high voltage to the magnetron 31, and various electrical components inside the body 10. It is comprised including the blowing fan 33.

In the conventional microwave oven having the above configuration, a lamp 41 for illuminating the inside of the cavity 20 is installed. The lamp 41 operates when the door 14 of the microwave oven is opened or food is being cooked in the cavity 20 so that the user can know the food cooking process.

Recently, many halogen lamps using the same voltage and having improved brightness have been adopted.

2 is a side view showing a lamp holder assembly 40 for fixing a lamp of a conventional general microwave oven.

As shown in the figure, the lamp holder 43 fastened to the lamp cover 42 has a circular cross section, the outer case of the lamp holder 43 is composed of a non-conductive plastic or ceramic. Two pin holes 431 are formed on the surface of the lamp holder 43 to insert the positive and negative pins of the lamp 41, respectively.

The lamp cover 42 is made of a reflective metal material and serves to double the brightness of the lamp 41 together with supporting the lamp holder 43.

The lamp is a halogen lamp, and commonly used incandescent lamps.

3 is a view showing a state in which the halogen lamp 41 is inserted into the lamp holder 43.

As shown in the figure, a worker or a consumer replaces the lamp 41 when the lamp reaches its end of life. When the lamp 41 is replaced, it is preferable that the protective gloves are worn in a state in which the lamp holder assembly 40 is pulled out to cut off the power of the microwave oven.

However, a consumer who uses a microwave oven at home may replace the lamp 41 while the microwave power is applied unconsciously. As shown in the drawing, a finger may be placed on the pin 411 of the lamp 41. The problem of contact and electric shock occurs.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and when the operator or consumer plugs the lamp that illuminates the inside of the microwave oven into the lamp holder, the structure of the microwave oven is improved so as to prevent electric shock. It is an object to provide a lamp holder for a cavity.

In order to achieve the above object, the present invention provides a lamp holder for a cavity of a microwave oven, wherein two pinholes into which a positive pin and a negative pin of a lamp are inserted are formed, and a protective wall made of a non-conductive material is formed around the pinhole. do.

In particular, the height of the protective wall is characterized in that at least 7mm.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of the lamp holder for the cavity of the microwave oven by this invention is demonstrated in detail, referring an accompanying drawing. For reference, in order to avoid duplication of description before describing the configuration of the present invention will be referred to the prior reference numerals as it is for the parts that are consistent with the prior art.

Since the general configuration of the microwave oven in which the lamp holder is mounted has been described in the related art, a separate description thereof will be omitted.

Figure 4 is a perspective view showing a preferred embodiment of the lamp holder for the cavity of the microwave oven according to the present invention.

As shown in the figure, the lamp holder 50 is generally made of a non-conductive plastic or ceramic material, the holder body 51 from which the lead wire 54 is drawn out, and protrudes toward the holder body 51 side; The fastening portion 52, the two pinholes 53 to which the pins 411 of the lamp 41 are inserted and connected, and a protective wall 55 surrounding the pinholes.

The holder body 51 is formed with a lead wire (out of which power is supplied from the outside) and an anode terminal and a cathode terminal to which the pin 411 of the lamp 41 is connected.

Fastening portions 52 protrude from both sides of the holder body 51, and holes 521 are formed in the fastening portions 52, so that the lamp holder 50 is fastened to the lamp cover (not shown). The fastening part hole 521 is configured to be fixed by a screw.

Two pinholes 53 are formed in the front portion of the holder body 51, and a protective wall 55 is formed around the pinhole portion. The inner cross section of the protective wall 55 is preferably formed in a rectangular or elliptical shape so that the pin of the halogen lamp can be easily inserted.

The protective wall 55 is preferably formed at least 7mm.

In addition, the protective wall 55 is preferably made of a ceramic material as well as plastic.

5 is a view illustrating a state in which the lamp 41 is inserted into the lamp holder 50 according to the present invention.

As shown in the figure, the operator or the consumer when the lamp 41 is fitted to the outer wall of the protection wall 55 of the lamp holder 50 and inserts the lamp pin 411 into the pinhole 53 inside the protection wall 55. At this time, after the lamp pin 411 is connected to the pinhole 53, there is no possibility that the pin 411 and the consumer's hand come into contact with the protection wall 55 at all.

That is, from the time when the lamp pin 411 starts to be inserted into the pinhole 53, the lamp pin 411 is disconnected from the outside by the protective wall 55, and the operator's hand is only the exterior glass of the lamp 41. It just comes in contact with

The above configuration eliminates the risk of electric shock even when the microwave oven is powered on when the lamp 41 is replaced.

The above embodiment is merely an example for expressing the technical idea of the present invention in detail, and it is apparent that various modifications may be made to the position, shape, and material of the components within the scope without departing from the technical spirit of the present invention.

When the lamp reaches the end of the life of the microwave oven or when the lamp is broken, the connection between the consumer's hand and the pin of the lamp is prevented. Can prevent the danger of
