Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an inspection window device that can easily inspect the inside of an air conditioner.

[0002]

[Prior art]

 Air conditioning refers to adjusting the indoor thermal and air environment according to the purpose, and is broadly divided into health air conditioning, which improves livability, and industrial air conditioning, which improves productivity and maintains product quality. Is done. For example, in order to accurately drive a computer or various precision machines installed in a room, it is necessary to keep it constant to prevent malfunction due to a change in room temperature due to a change in atmospheric temperature. Air conditioners are installed.

As shown in FIG. 1, room air taken in from an air inlet 2 provided in a lower portion of an air conditioner 1 passes through an air filter 3 and is taken into a blower 4, and is blown out from an outlet 5 of the blower. If necessary, the temperature of the air is adjusted to a predetermined temperature when passing through a cold / hot water coil 6 in which hot or cold water is circulating. Then, the air is blown into the room from the air outlet 9 provided at the upper part of the air conditioner 1 to maintain the room temperature at a predetermined temperature, and absorbs and removes dust in the room air to clean the room air. It prevents erroneous operations and maintains a good working environment.

The coarse dust floating in the air is first removed by the air filter 3, and then the fine dust is removed by the cold / hot water coil 6, which is stored in a drain pan 7 provided below the cold / hot water coil 6. The drain water is collected in a drain tank (not shown) through a drain pipe 8 connected to a drain port (not shown) provided in a drain pan.

However, when large cotton dust or the like contained in the air enters the drain pan 7, the drain port is clogged and the drain water does not flow into the drain pipe 8 and overflows. In some cases, the float switch (not shown) does not operate and the water supply does not stop, so that the drain water overflows from the drain pan 7 and floods the floor in the room.

[0006] In this case, if it is delayed to notice the overflow, the water drops from the ceiling downstairs, and the water enters the computer and various precision devices to cause a failure. In the event of such a flood accident, there was a problem that a great deal of time was required for its recovery.

Since the conventional air conditioner 1 generally does not have a window for internal inspection, it is not possible to directly check the dirt condition in the air conditioner from the outside. For this reason, the panel 11 constituting the main body of the air conditioner, that is, the bolts 11 fixing the four corners of the side plate 10 are removed and inspected and cleaned at regular intervals, and the four corners of the side plate are bolted again. It is stopped and maintenance work is being performed. Thus, when inspecting and cleaning the air conditioner, the preliminary work of removing and attaching the side plates 10 one by one has to be performed, so that the work efficiency of maintenance and inspection is extremely poor.

[0008]

[Problems to be solved by the invention]

 If the side panel 10 of the air conditioner 1 does not have the inspection window as described above, the inside dirt state cannot be determined unless the side panel 10 is removed. Furthermore, the dirt condition inside the air conditioner 1 differs depending on the installation location of the air conditioner, the use environment, and the like. As described above, in order to perform maintenance and inspection without confirming the degree of contamination, it was necessary to remove the side plate 10 and perform internal inspection and cleaning for maintenance and inspection in a short period of time. For this reason, there was a problem that maintenance operation was inevitably increased and maintenance and inspection costs were required.

In view of such circumstances, the present invention is a state in which an air conditioner is driven by an inspection window device which is installed in an inspection hole provided in a side plate of the air conditioner so that an internal inspection can be easily performed. The purpose of the present invention is to provide an inspection window device for an air conditioner that allows an operator to easily perform an internal inspection while directly checking the state of the air conditioner.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention provides a mounting substrate having a stopper provided at a lower portion of a vertically provided guide groove on both sides of a front surface and having small mounting holes formed on both sides of an opening provided at a central portion. Forming an inspection window at the center portion to match the opening of the mounting board, providing mounting holes on both sides of the inspection window at positions matching the mounting small holes, and accommodating both side ends in the guide groove. An air conditioner comprising: a synthetic rubber plate to be attached to the front surface of the mounting substrate and a transparent cover body made of transparent resin and having a handle at the top of the front surface and accommodated vertically in the guide groove of the mounting substrate. Attach the mounting board with the inspection window and opening aligned with the inspection hole provided in the side plate of the side plate with screws, and move the transparent cover body that opens and closes the inspection window up and down in the guide groove. Characterized by being accommodated as much as possible. .

Further, the guide grooves provided on both sides of the front surface of the mounting board according to the present invention are provided with stoppers formed by bending a protruding piece continuously provided below a front folded piece constituting the guide groove. It is characterized by becoming.

Still further, the synthetic rubber plate according to the present invention is colored in the same color as a side plate of an air conditioner and is adhered and fixed to a front surface of the mounting board.

According to the above means, the following effects can be obtained. That is, the transparent cover body, which is vertically movable within the guide groove of the mounting board, receives a negative pressure from the inside during the operation of the air conditioner and adheres tightly to the synthetic rubber plate. Absent. Also, since the inside of the air conditioner can be checked through the transparent cover, if the drain port of the drain van is likely to be clogged, lift the transparent cover while the air conditioner is running, open the inspection window, and insert your hand. Simple maintenance and inspection can be performed, such as taking out dust and the like, and flooding accidents can be prevented.

Although the synthetic rubber plate may be a simple black rubber plate, the color may be different from that of the side plate, which may cause a sense of incongruity and make it impossible to work. In this case, if it is formed in the same color as the side of the air conditioner, you can work calmly without any discomfort. Furthermore, if a synthetic rubber plate is adhered to the front surface of the mounting board with an adhesive, the number of parts handled on site is reduced, and the workability is facilitated without the synthetic rubber plate falling off the mounting board. .
