Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an air conditioner that reliably rectifies the air flow flowing through the inside of the machine, produces low noise, and has excellent heat exchange efficiency.

[Conventional technology]

Normally, in a terminal type air conditioner, indoor air is sucked in through a suction port on one side of the machine, heat is exchanged with a heat exchanger inside the machine, and air is sent to each room from the air outlet through an air distribution mechanism such as a duct. Most of these air conditioners used to supply cold and hot air every time they were operated, but the fact that most of these air conditioners had almost direct current airflow inside the machine caused some drawbacks, such as the generation of noise during operation. Ta.

[The problem that the idea aims to solve]

In view of the above-mentioned drawbacks, the present invention forms an air ventilation passage into an L-shaped ventilation passage, and further provides an energy-saving type of air conditioner with very low noise by attaching a mechanism described in detail below to the ventilation passage. The main purpose is to provide a wide range of machines.

[Means to solve the problem]

In order to achieve the above object, the air conditioner according to the present invention has an L-shaped air passage 2 and a heat exchange chamber 6 formed in the body 1, and a blower 5 in the air passage 2.
In addition, mechanical devices such as a heat exchanger 8 and a drain pan 7 are arranged in the heat exchange chamber 6, and a projecting piece 10 is installed at the bent inner corner of the air passage 2.
Its feature is that it extends inside.

Additionally, in addition to the above, a filter mount 11 having a lower bottom surface formed as an inclined surface is protruded from the inner wall portion of the machine casing on the opposite side of the protruding piece 10 extending into the air passage 2, and a filter mount 11 is provided protrudingly from the inner wall portion of the machine casing on the opposite side of the protruding piece 10 extending into the air passage 2. By forming a narrow air passage a in the air, more stable heat exchange efficiency can be obtained.

[Effect]

In the above structure, the indoor air or fresh outside air sucked in from the suction port 3 flows into the L-shaped air passage 2 as shown by the arrow, and this air is removed from the inside of the air passage 2 while removing dust by the plurality of filters 12, 12. It passes through the narrow ventilation path a.

Further, the airflow is constricted in the narrow airflow path a, naturally rectified, and flows back toward the blower 5.

During the above-mentioned air flow, the airflow is diffused by the action of the protruding pieces 10 attached to the two corners of the airflow path, so that the backflow air is evenly distributed throughout the both side blowers 5 and throughout the heat exchanger 8. The air can be distributed approximately equally.

Therefore, it is possible to easily obtain an air conditioner that has extremely good heat exchange efficiency and also has extremely low noise.

〔Example〕

Hereinafter, embodiments of the present invention will be explained in detail with reference to the drawings. 1 is a machine body having a suction port 3 on one upper side and an air outlet 4 on the other side. A blower path 2 is formed, a blower 5 is installed on one side of the lower part, and a heat exchange chamber 6 is formed on the upper side of the blower side of the blower 5, and mechanical devices such as a drain pan 7 and a heat exchanger 8 are arranged in the chamber. do.

Note that the above-mentioned air passage 2 and heat exchange chamber 6 are separated by a partition plate 9.
As shown in the first figure, a protruding piece 10 of an appropriate length is provided at the bent corner of the partition plate 9 on the inside of the air passage 2 so as to protrude into the air passage 2. It becomes.

Further, the present invention has a filter mount 1 having a lower bottom surface formed as an inclined surface 11' at an appropriate angle on the opposite side of the protruding piece 10, that is, on the inner wall portion of the machine casing separated by an appropriate gap.
1 is attached in a protruding manner to form a narrow ventilation path a in a part of the ventilation path 2, and a prefilter,
The number of filters 12 such as a main filter is increased or decreased as appropriate depending on the type of dust, and the filters 12 are arranged obliquely.

In the drawings, reference numerals 3A and 4A indicate preliminary suction ports and blowout ports using dotted lines, and the opening positions are not limited by the installation location of the main body.

[Effect of idea]

As described above, in the air conditioner according to the present invention, the filter mount 11 is provided protrudingly in a part of the L-shaped air passage 2, and a part of the air passage is formed into a narrow air passage a, which circulates inside the air passage 2. Ensure that the air flow is rectified.
Moreover, since the above-mentioned airflow is sent almost uniformly to the double-shaft blower 5 by the action of the protruding piece 10, and the air is applied to the entire heat exchanger 8, the heat exchange efficiency is extremely good. It has various advantages such as energy saving and extremely low noise.
