    An assembling structure of UV lamp for microwave-oven}
    [13] The present invention relates to a microwave oven, and in particular, the upper and lower sides of the ultraviolet lamp which is installed on the cooking chamber of the microwave and sterilizes the inside of the cooking chamber by a cover, and the ultraviolet lamp is attached to the holder for the glow lamp. By fixing it, the installation work of the ultraviolet lamp is simplified, and the electrode and the connecting piece of the ultraviolet lamp are sealed from the outside, thereby preventing damage or short-circuiting of the electrode and the connecting piece due to steam generated during cooking.
    [14] In general, unlike microwave cooking utensils by heat conduction or heat radiation, microwaves are cooked as a dielectric heating according to the translational movement of water molecules contained in the food, and microwaves are prepared by applying high voltage electricity to an ultra-high frequency oscillator tube called magnetron. The food is cooked by the ultra-high frequency generated by the addition.
    [15] In particular, the microwave oven heats the inside and the outside of the food at the same time, which greatly reduces the thawing or cooking time of the food by high thermal efficiency, and reduces the loss of nutritional value during the cooking, thawing and warming of the food. It is widely used due to its advantages such as cooking in a container.
    [16] Such microwave ovens are equipped with a magnetron and a high voltage transformer to generate microwaves, a circuit for controlling the operation of the microwave and a cooling fan, and the like, and the side of the electric chamber requires cooking. While providing a storage space for food, a cooking chamber is provided to heat the food according to the diffusion of microwaves.
    [17] On the other hand, the microwave oven having such a structure, the food containing water is cooked due to the nature of use, while the food is scattered from the container during the cooking process of the microwave provides a favorable environment for the growth of bacteria inside the cooking chamber.
    [18] Therefore, since there is a high possibility of the growth of bacteria harmful to the human body inside the cooking chamber of the microwave, recently, by installing an ultraviolet lamp having a sterilization characteristic by a specific wavelength inside the cooking chamber, various bacteria in the cooking chamber are sterilized. Microwave ovens are being used for hygienic cooking.
    [19] 1 is a view illustrating an example of a microwave oven 400 in which an ultraviolet lamp 100 is installed on the ceiling plate 310 of the cooking chamber 450 as described above, and the conventional microwave oven 400 is a cooking chamber. The ceiling plate 310 of 450 is recessed in an upward direction, and the ultraviolet lamp 100 is mounted inside the space above the ceiling plate 310.
    [20] The UV lamp 100 has a ceiling plate 310 in which both ends are supported by sockets 350 having internally connected contacts for connecting to electrodes of the UV lamp 100, such as sockets of a conventional fluorescent lamp. It is mounted horizontally from the top of the.
    [21] On the other hand, the microwave oven 400 is a food containing moisture is cooked because a large amount of water is emitted during the cooking process, as described above the water emitted from the food space between the ultraviolet lamp 100 and the socket 350 In the case of condensation, not only the electrode and the contact are damaged, but also short circuit occurs due to the condensed water.
    [22] However, the conventional socket 350 has a structure in which the contact surface with the ultraviolet lamp 100 is open and condensed with a problem such that metal parts such as electrodes and contacts are damaged by moisture emitted during the cooking of food. The short circuit caused by moisture causes a problem of a safety accident.
    [23] In particular, since the conventional socket 350 has to fasten the screw through a narrow space in the coupling process with the ceiling plate 310, the workability is reduced, which requires a lot of manpower and time.
    [24] The present invention is to solve the conventional problems as described above, the technical problem of the present invention is installed on the upper part of the cooking chamber of the microwave oven to support the lower sides of the ultraviolet lamp to sterilize the inside of the cooking chamber by the cover, By fixing the UV lamp according to the attachment of the holder for the glow lamp, the installation of the UV lamp is simplified and the electrode of the UV lamp is sealed from the outside to prevent damage or short circuit of the electrode by steam generated during cooking. It is to provide means that can be.
    [25] Technical problem of the present invention as described above,
    [26] In the combined structure of the ultraviolet lamp provided on the cooking chamber ceiling plate of the microwave oven to sterilize the inside of the cooking chamber,
    [27] On one side of the cover attached to the cooking chamber ceiling plate of the microwave oven, a through hole having a flat surface is formed in the upper and lower portions so that the fixing cap of the UV lamp holder is inserted, and in the other end, a square incision hole having an opening in the upper portion is formed. In addition, the side surface of the cover is formed with a rectangular cut hole is achieved by providing a coupling structure of the ultraviolet lamp for microwave oven, characterized in that made of a structure in close contact with the holder for the glow lamp.
    [28] Hereinafter, the coupling structure of the ultraviolet lamp for microwave oven according to the present invention will be described in detail with the accompanying drawings.
