[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a refrigerator, a refrigerator / freezer-type freezer, a freezer-type freezer, a freezer-only food stocker, a showcase, an indoor beverage vending machine for business use, a water cooler, a juice cooler, etc. Dust and dust are prevented from entering through the lower gap of the electrical equipment where the capacitor and the electrical wiring connecting them are exposed to prevent dust and dirt from accumulating on the exposed part. It is also related to the intrusion prevention frame for dust and dirt.

[0002]

[Prior art]

 Conventionally, compressors, fan motors, condensers, and electrical wiring that connects them are built into the bottom of the main unit, and partially exposed electric devices such as refrigerators radiate heat from each function toward the floor from the bottom of the main unit. There is a gap between the bottom of the main unit and the floor because it is forcedly cooled by a forced fan.Dust and dust infiltrate through the gap and collect on the exposed part, or the intake part of a fan motor or condenser. The heat dissipation effect is reduced due to the attachment to the refrigerator, and the cooling power is reduced especially in the case of refrigerators, resulting in the waste of power consumption, which in turn induces a short circuit in the electrical wiring, etc. Was becoming.

For these reasons, it is necessary to regularly remove and clean dust and debris accumulated by moving refrigerators, but mainly housewives and children, and more recent refrigerating cabinets. Since it is almost impossible to move refrigerators with the increase in size of the equipment and it is a place that is difficult for human eyes to touch, there is a strong tendency to leave it alone. They had the disadvantage that harmful insects such as cockroaches and 20-day rodents entered and combined with the accumulated dust and debris, the lower gap of the refrigerators became an unsanitary environment.

[0004]

[Problems to be solved by the device]

 The present invention prevents dust, dirt, and pests from entering from the lower clearance of an electric device, and prevents dust and dirt from accumulating on externally exposed parts such as a compressor, a fan motor, a condenser, and electric wiring connecting them. By eliminating the need for periodical removal and cleaning work, improving the hygiene of the lower clearance, and preventing functional deterioration and failure due to accumulated dust, dirt, and pests that have entered, it is possible to save electricity and electricity. It is intended to provide a frame for preventing intrusion of dust, dust, etc. into the lower clearance of an electric device in order to improve the life of the device.

[0005]

[Means for Solving the Problems]

 The present invention is based on the above-mentioned conventional technology, and in view of the problem that dust, dust, and pests intruding from the lower clearance adversely affect electric devices such as refrigerators, the L-shaped corner plates are arranged at the four corners, and A side plate is placed between the mold corner plates, and both ends of the side plates are slidably mounted on the corner members of the L-shaped corner plate to allow expansion and contraction. The above-mentioned drawbacks cannot be solved by closing the lower gap by enclosing it and closing the lower gap to prevent invasion of dust, dust, pests and the like from the lower gap.

[0006]

[Action]

 In the present invention, by making it expandable and contractible, it can be used for all sizes of electric equipment, and the main body is set so as to surround the lower gap of the electric equipment, and the inner surface of the L-shaped corner plate and the side plate. To prevent the ingress of dust, dirt, pests, etc. by closing the lower gap until it comes into contact with the outer surface of the electrical equipment, and the infiltration of dust, dirt, etc. by the mesh part of the side plate. The ventilation is good.

Further, in the case where the back corner of the electric device M is largely chamfered, the fitting plate 21, which matches the clearance of the right triangle formed by the chamfered surface and the rear L-shaped corner plates 3 and 3a, 21a is fitted in the fitting grooves 20, 20a of the rear L-shaped corner plates 3, 3a to close the above gap.

Further, the side plates 4, 4a ... Having the net portions 23, 23a ... Have good air permeability, and only fresh air from which dust, dust, etc. have been removed by the net portions 23, 23a. It is being fed into the gap S.

[0024]

[Effect of device]

 In short, according to the present invention, the side plates 4, 4a ... Are arranged between the L-shaped corner plates 2, 2a, 3, 3a arranged at the four corners, and both end portions of the side plates 4, 4a. Since it is slidably attached to 2a, 3 and 3a, the lower gap S can be closed by setting the main body 1 so as to enclose the lower gap S and contracting it, so that dust, dust and pests from the lower gap S can be closed. Can prevent the intrusion of dust, thus eliminating the need for regular removal and cleaning work of dust, dust and pests, and improving the hygiene of the lower clearance S, which is caused by accumulated dust, dust and pests that have entered. By preventing the deterioration of function and the occurrence of failure, it is possible to save power and improve the life of the electric device M.

Further, since each L-shaped corner plate 2, 2a, 3, 3a can be divided and assembled into the corner members 5, 5a, the corner members 5, 5a can be slid on both end portions of each side plate 4, 4a. When mounted on its own, the side plates 4, 4a ... In this state are substantially flat plate-shaped, and therefore the main body 1 is not bulky even in the disassembled state, and is therefore easy to handle during transportation and assembly.

Further, since the net portions 23, 23a ... Are provided in the openings 22, 22a ... Provided in the side plates 4, 4a ..., the air permeability is good and dust, dust, etc. are eliminated by the net portions 23, 23a. Since fresh air flows into the lower clearance S from the outside, the cooling effect of the refrigerators can be further improved, which is a great practical effect.
