There is provided an air conditioner that ventilates while exchanging heat with the air that is exhausted. In the above-mentioned air / air conditioner, in order to remove dust and the like contained in the indoor air, an indoor air circulation duct for circulating the indoor air through a filter or the like is provided, and further, from this indoor air circulation duct There was a system in which indoor air was distributed to the exhaust air and the return air by connecting the branch duct to the exhaust duct. However, in this air conditioner, there is a problem in that the size of the entire air conditioner increases because the dispersed devices are connected by ducts.

On the other hand, as disclosed in Japanese Patent Laid-Open No. 62-194133, a heat exchanger 95 is provided in the air conditioner body 90.
A connecting air passage 93 that connects the air supply side air passage 91 and the exhaust air side air passage 92 intersecting with each other is provided, and a part of the exhaust air side air passage 92, a connecting air passage 93 and a part of the air supply side air passage 91. There is also provided an indoor air circulation air passage 94 configured by a path flowing through. However, in this air conditioner, the differential pressure between the air supply side air passage 91 and the exhaust air side air passage 92 changes due to the effect of clogging of the filter 96, for example, and thus the balance between air supply and exhaust air. There was a problem that it was easy to collapse.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above technical problems and to provide an air conditioner which can maintain a good balance between air supply and exhaust and can be downsized.

[0005]

The air conditioner according to claim 1 for achieving the above object comprises a heat exchanger for exchanging heat between the air supply from the outside and the exhaust air from the room, and an electric machine. An air conditioner main body that combines at least one of a dust collector, a deodorizer, and a humidifier, and an air supply side air passage that guides the air from the outside to the room and an exhaust side that guides the air inside the room to the outside. An air passage and an indoor air circulation air passage that circulates the indoor air in a state independent of the air supply side air passage and the exhaust air side air passage are provided, and the air supply side air passage downstream portion of the heat exchanger in the air blowing direction. Is extended to the downstream side in the air blowing direction with the air passage width narrowed by the diaphragm partition that is inclined with respect to the air blowing direction, and the indoor air circulation air passage is the air passage of the air supply side air passage. It is attached to the narrowed part, and the air intake of the indoor air circulation air passage is air-conditioned. The end face of the apparatus main body, in a position facing the partition plate throttle above is characterized in that in the direction perpendicular to the blowing direction of the air supply is opened.

[0006]

According to the above construction, in the air conditioner body,
Since the indoor air circulation air passage is provided independently of the air supply side air passage and the air exhaust side air passage, it is easy to maintain a predetermined balance between the air supply amount and the exhaust amount. Moreover, since the indoor air circulation air passage is provided side by side in the portion where the passage width of the air supply side air passage is narrowed, the entire air conditioner can be downsized.

Further, since the intake port of the indoor air circulation air passage is opposed to the diaphragm partition plate for narrowing the air supply side air passage, the supply air is blown from the intake port into the indoor air circulation air passage. The air in the room introduced along the direction orthogonal to the direction,
The diaphragm partition plate guides the air in a direction parallel to the air blowing direction. Therefore, the diaphragm partition plate for restricting the air supply side air passage can also serve as a guide plate that smoothly changes the direction of the flow in the indoor air circulation air passage.

An attached hole 31 as an attached portion corresponding to 30 and an attached hole 51 as an attached portion corresponding to the side edge side attachment member 50 are provided.
By screwing the nuts into the mounting screws 60 that penetrate the through holes of the upper edge side mounting member 30 and the mounting holes 31, the upper surfaces of both casings are screwed together. Further, the nuts are screwed into the mounting screws 60 penetrating the through holes of the side edge side mounting member 50 and the mounted holes 51, so that the side surfaces of both casings are screwed together. The lower edge side attachment member 40 hooks the hook portion at the tip thereof to the lower edge portion of the casing to cooperate with the other attachment members 30 and 50 to attach the casings to each other.

[0020] FIGS. 6-8, the step of connecting the casing to each other, are sequentially shown as an example the case of a connection between the casing Vc and the casing Cc electrostatic precipitator machine unit CU of the basic unit VU. First, as shown in FIG. 6, both casings Vc and Cc are placed on the ceiling surface or the like, and as shown in FIG. 7, the right casing Cc is lifted and brought close to the left casing Vc. In this state, the height of the right casing Cc allows the upper edge side mounting member 30 of the left casing Vc to enter.
Moreover, the height is such that the lower edge side mounting member 40 of the right casing Cc can be inserted into the left casing Vc. Then, by lowering the left casing Cc until it comes into contact with the ceiling surface while bringing the right casing Cc close to the left casing Vc, the through hole of the upper edge side mounting member 30 of the left casing Vc becomes smaller than that of the right casing Cc. It is aligned with the mounting hole 31. Also,
The lower edge side mounting member 40 of the right casing Cc is engaged with the lower edge of the left casing Vc. Further, the through hole of the side edge side attachment member 50 of the left casing Vc is aligned with the attached hole 51 of the right casing Cc, and is screwed.

With reference to FIG. 9, the upper edge side mounting member 30 and the mounting hole 31 regulate the order in which the units are combined, and exclude unfavorable combinations from the free combinations of the units. The positions are offset from each other so that The distance between the pair of upper edge side mounting members 30 is set to the pitch b or c, and the pair of mounting holes 3
As the distance between 0s, two types are provided: one that is compatible only with the pitch b and one that is compatible with both the pitch b and the pitch c. In the former case, each of the pair of attached holes 30 is formed by a circular hole, and in the latter case, one of the pair of attached holes 30 is (b-
It has a long hole longer than c).

In FIG. 9, the matching relationship of the combination order of each unit is shown by a solid arrow, and the non-matching relationship is shown by a broken arrow. As shown in FIG. 9, while the distance to what on edge attachment member 30 of the humidifier unit HU is pitch c, a pair of electric precipitator machine unit CU and deodorizer unit DU No and if the mounting holes 31 distance is set only to the pitch b, thereby, humidifier unit HU electric precipitator machine unit CU and deodorizer unit DU
It is prevented from being arranged on the upstream side in the air blowing direction. This is because if the humidifier unit HU is arranged on the upstream side, the humidified and moist air will be the electrostatic precipitator.
This is to prevent the occurrence of a failure such as loss of electrical insulation due to the flow in the machine unit CU or the deodorizer unit DU, and to prevent this. On the other hand, the humidifier unit HU and the blower unit FU have one attached hole 31 as a long hole so that they can be arranged on the downstream side in the blowing direction of any other unit. Further, deodorizer unit DU is restricted so as not to be located upstream of the electrostatic precipitator machine unit CU.

According to this embodiment, the air conditioner body A
Since the indoor air circulation air passage 17 is provided inside the air supply passage 15 and the exhaust air passage 16 independently of each other, it is easy to maintain a predetermined balance between the air supply amount and the exhaust amount. .
Further, the air supply side air passage 15 can be directly connected to the air conditioner for cooling and heating by a duct. Moreover, the air passage 1 on the air supply side
In the portion where the passage width of 5 is narrowed, the indoor air circulation air passage 17
Since it is installed side by side, the entire air conditioner can be downsized.

Further, the suction port 1 of the indoor air circulation air passage 17
0a denotes a diaphragm partition plate 70 for restricting the air supply side air passage 15
The air in the room introduced from the suction port 10a into the indoor air circulation air passage 17 along the direction orthogonal to the air blowing direction of the air is blown by the diaphragm partition plate 70. Guided in a direction parallel to the direction. Therefore, in the diaphragm partition plate 70 for restricting the air supply side air passage 15,
The function of smoothly changing the direction of the flow in the indoor air circulation air passage 17 can be shared, and the structure can be simplified.

Further, a composite unit is constructed by connecting at least one unit selected from the electrostatic precipitator unit CU, the deodorizer unit DU, the humidifier unit HU and the blower unit FU in series to the basic unit VU. Therefore, it is possible to realize an air conditioner in which only desired units are freely combined. Moreover, since the casings of the units are connected by the mounting members instead of connecting the units by ducts as in the conventional case, the size of the entire air conditioner can be reduced.

In the above embodiment, the air conditioner is constructed as a composite unit of each unit, but it may be constructed as a single unit composed of an integral casing. Further, the blower fans 20 and 21 can be arranged in the air supply second space 9 and the circulation first space 10 of the basic unit VU respectively without providing the blower unit FU.

Further, each mounting member 30, 40, 50
Can be formed integrally with the casing, and various modifications can be made without departing from the scope of the invention.

[0028]

As described above, according to the air conditioner of the present invention, the indoor air circulation air passage is provided in the air conditioner main body independently of the air supply side air passage and the exhaust side air passage. Therefore, it is easy to maintain a predetermined balance between the air supply amount and the exhaust amount. Moreover, since the indoor air circulation air passage is provided side by side in the portion where the passage width of the air supply side air passage is narrowed, the entire air conditioner can be downsized.

Further, the diaphragm partition plate for restricting the air supply side air passage can also serve as a guide plate for smoothly changing the direction of the flow in the indoor air circulation air passage. The structure can be simplified, and the air conditioner can be downsized.
