Description

[Detailed description of the invention] The present invention aims to provide an air conditioner that does not have an internal lighting device and allows the internal operating status to be easily inspected from outside without stopping the operation. purpose.

Conventionally, the viewing window for internal inspection in this type of air conditioner has been a rectangular window of about 20 x 30 cm or a round window of about 17.5 cm in diameter at a predetermined position. The walls of the container are provided with thermal insulation measures.

However, in the case of the rectangular window, the area of the viewing part is relatively large, so even if there is no lighting device installed inside the container, the interior can be illuminated with a flashlight or the like from outside the viewing window. Although it has the advantage of being able to easily see the inside of the vessel through the same viewing window, on the other hand, the glass area of the viewing window (0.2 x 0.3 = 0.06 m ² )
Heat loss is large due to the large amount of heat, and since air that has been cooled or heated by an air cooler or air heater is often passing through the container, heat transfer and radiation between the outside and outside of the container can occur through the glass surface of the viewing window. There is a heat transfer loss due to this, which not only reduces the efficiency of the air conditioner but also causes a large loss of energy.

Therefore, in order to eliminate the above disadvantage, it can be solved by reducing the size of the viewing window, but as mentioned above, in the case of a small-diameter round viewing window, the area is smaller than the former, so the heat loss is higher. However, when viewing the inside of a container without an illumination device, it becomes extremely difficult to illuminate the inside of the container with a flashlight through the observation window while visually viewing the inside of the container through the same window.

The present invention eliminates the above-mentioned conventional inconveniences, makes it possible to easily inspect the inside of the air conditioner from the outside, targets air conditioners that do not have a lighting device inside the air conditioner, and creates a unit with less heat loss. The air conditioner 1 is characterized in that two or more comparatively small viewing windows 2 for internal inspection are arranged at appropriate positions on the side wall surface of the air conditioner 1.

Embodiments of the present invention will be described with reference to the drawings.

In the drawing, 1 indicates a mixing box 1a, a filter 1b, a communication box 1c, a connecting canvas 1d, a coil box 1e, and a fan box 1.
It is a unit type air conditioner consisting of a combination of f, and the appropriate places on the side wall, that is, in the illustrated example, a filter, a humidifying part,
Two viewing windows 2 are provided at easy-to-see positions for inspection of the fan, and each viewing window 2 is closed with a transparent glass, through which the inside of the device can be inspected.

The size of each viewing window 2 is smaller than that of the conventional one, about 10 cm in diameter, and two or more viewing windows 2 are provided at one location.

Thus, when inspecting the inside of the vessel, the inside of the vessel is illuminated with a flashlight through one of the viewing windows 2 installed at the inspection point, and inspection can be easily made from the other viewing window 2, depending on the size of the viewing window. In comparison with the conventional example regarding heat loss, the area of one square window of 20 x 30 cm in the conventional example is 0.06 m ² 〃 Round window with a diameter of 17.5 cm 〃 〃 〃 〃 〃 0.023 m ² The proposed design has a diameter of 10.0 cm 〃 2 〃 0.016 m ² For example, compared to the area of 1 piece with a diameter of 15 cm, which is 0.018 m ² , the area for two pieces in this invention is small, so the heat loss due to heat transfer and heat radiation is proportionally small. Moreover, even if the diameter of each viewing window is small, the provision of two viewing windows is advantageous because one can be used for illumination and the other for inspection.

In this way, according to the present invention, two or more viewing windows 2 are provided at each location of the air conditioner 1 that requires inspection.
Because of the arrangement of the windows, it is much more convenient to use than the conventional case where one window is set up in an advantageous position for illumination and the other window is for inspection, inspection is accurate, and individual The size of the window can be smaller than the conventional one, and there is less heat loss than the conventional one, so the operation can be stopped in an air conditioner that does not have an internal lighting device without reducing the air conditioning efficiency. This has the effect of making it easier and more accurate to inspect the inside of the container from the outside.
