Abstract

PURPOSE:To be able to easily switch a product of one type between feed air specification and exhaust air specification, by providing a bulkhead between an indoor unit and an outdoor unit as well as to provide an opening on the bulkhead, by providing a two-wings damper to the opening, and by providing a shutter on the side of an indoor fan. CONSTITUTION:At the time of exhaust air specification, a lower opening 36b of a shutter 40 fitted to an indoor fan 26 is closed. When the opening 36b is closed, a damper 38 is opened to the position shown by an actual line. Most of air is passed through an indoor heat exchanger 25 by the indoor fan 26 and is diffused from an indoor diffuser 28, but part of air flows to an outdoor unit 35 as shown by an arrow sign A, flowing in the outdoor unit 35 from an outdoor feed air port 33, routed through an outdoor heat exchanger 31 by an outdoor fan 32, and is discharged to the outside together with outdoor air. When feed air specification is required, a fixing screw 44 is taken off, and the shutter 40 is reversely fitted down-side up. When the upper opening 36a of a bulkhead 30 is shut and the damper 38 is opened, most of the outdoor air flowing in from the outdoor feed air port 33 is discharged to the outdoors from the outdoor discharge port 34 by the outdoor fan 32.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a ventilation system for a wall-penetrating individual air conditioner.

2. Description of the Related Art Conventionally, a wall-penetrating individual air conditioner installed in a verimeter zone of a building or the like has a configuration as shown in FIGS. 3 and 6. In the system shown in FIG. 4, a louver 2 and a sleeve 3 are provided on the outside of an outer wall 1, and a main body 4 of an individual air conditioner is housed in the sleeve 3. 6 and indoor blower 6
an indoor unit section 7 provided with an outdoor heat exchanger 8 and an outdoor blower 9; and an outdoor unit section 1o provided with an outdoor heat exchanger 8 and an outdoor blower 9; has been established. An opening 12 is provided below the partition plate 11, and a damper 13 for opening and closing the opening 12 is provided. When outdoor air is to be supplied, the damper 13 is opened (dotted line position in the figure), and air flows in from the outdoor air supply port 14 to the outdoor blower 9. It passes through the outdoor heat exchanger 8 and is blown out through the outdoor air outlet 16, but a part of the air at this time flows into the indoor unit section 7 through the opening 12 and mixes with the indoor air that has flowed in through the indoor suction port 16. and indoor blower6. It passes through the indoor heat exchanger 5 and is blown into the room through the indoor air outlet 17, thereby supplying outdoor fresh air into the room, thereby creating an individual air conditioner with air supply specifications.

On the other hand, the air conditioner shown in FIG. 6 has an opening 18 above the partition plate 11 of the main body 4 of the same type for exhausting indoor air, and the damper 13 is opened (dotted line position in the figure). Accordingly, while the indoor air flowing in from the indoor suction port 16 passes through the indoor blower 6, a part of the indoor air along with the air flowing in from the outdoor air supply port 14 passes through the outdoor heat exchanger 8 and reaches the outdoor air outlet. From 15 onwards, the air was blown outside.
As a result, indoor air is exhausted outdoors.

As shown in FIGS. 4 and 6, the wall-penetrating air conditioner in which the indoor unit part 7 and the outdoor unit part 1o are provided in front and behind each other with a partition plate 11 interposed therebetween is conventionally used in buildings, etc. Depending on the building conditions, we have air supply specification products shown in Figure 4 and exhaust specification products shown in Figure 5, depending on whether the purpose of the building is air supply or exhaust. The product model was selected.

Problems to be Solved by the Invention In such a conventional configuration, it is necessary to decide at the architectural design stage whether to use an exhaust specification product or an air supply specification product. (Fig. 4), or a grip specification product (Fig. 4).
Figure 5) is selected, shipped, and installed in the perimeter zone. However, once the installation is delivered to the site or after the installation is completed, due to changes in the user's requests due to changes in the building environment, the air supply specification product (Fig. 4) is replaced with the exhaust specification product (Fig. 5). ) or vice versa, it takes a lot of effort to replace the specified product. In particular, if a request for a change is made after the installation has almost been completed by penetrating the wall, there is a problem in that it requires work such as removal and transportation, which takes a lot of time and effort.

The present invention solves these problems, and aims to provide an air conditioner that can be easily converted to either the air supply specification or the exhaust specification.

Means for Solving the Problem In order to solve this problem, the present invention provides an indoor unit having an indoor heat exchanger and an indoor blower, an outdoor unit having an outdoor heat exchanger and an outdoor blower, and an indoor unit having an indoor heat exchanger and an indoor blower. In a wall-penetrating individual air conditioner equipped with a partition plate that partitions a unit part and the outdoor unit part, an opening is provided in the center of the partition plate, dampers of both wings are provided in the opening, and an indoor blower is provided. , formed in an L shape so that when the dampers of both wings are opened, either the opening above the partition plate opening or the lower opening below the partition plate opening is closed, with the center of the partition plate opening serving as a fulcrum. It is equipped with a shielding plate.

Effect With this configuration, when setting the exhaust specification product, the indoor blower is installed so that the shielding plate fixed to the indoor blower covers the lower side of the opening of the partition plate, and exhaust is performed.
In addition, when setting the air supply specification product, use a shielding plate fixed to the indoor blower to cover the upper side of the opening to supply air, and select either the exhaust specification product or the air supply specification product. This will be done by.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. In FIG. 1, reference numeral 21 denotes the main body of the wall-through air conditioner, which is housed inside a sleeve 23 fixed through an outer wall 22, and a louver 24 is provided on the outside.

This main body 21 is an indoor heat exchanger 26. an indoor unit section 29 that includes an indoor blower 26 and an indoor suction port 27 on the lower side and an indoor air outlet 28 on the upper side; and an outdoor heat exchanger 31 that is provided within the sleeve 23 with a partition plate 30 interposed therebetween. An outdoor air supply port 33 equipped with an outdoor blower 32 and facing the louver 24
and an outdoor unit section 35 having an outdoor air outlet 34.

An opening 36 communicating with the outdoor unit 36 and the indoor unit 29 is provided in the center of the partition plate 30, and a mounting plate 37 for the outdoor blower 32 is located approximately at the horizontal center of this opening 36. A double-winged damper 38 is provided which operates at an angle of about 46 degrees to open and close the opening 36.

In FIG. 3, the indoor blower 26 includes an indoor blower 2
6 and the mounting plate 39 has an L-shaped opening 36 on the partition plate 30 side.
A shielding plate 40 is provided to shield the upper opening 36a, or to be attached upside down in the vertical direction to shield the lower opening 36b. The shielding plate 4o is provided to be slightly larger than the area of the upper opening 36a and the area of the lower opening 3eb so that it can be shielded.

41 and 42 are holes for fixing the indoor blower 26 integrated with the mounting plate 39 on the sides of the partition plate 30. Also 4
3 is a damper motor.

In the above configuration, if there is a request for an exhaust specification product due to architectural conditions or style, the shielding plate 40 attached to the indoor fan 26 closes the lower opening 36b, as shown in FIG. do. That is, the lower opening aeb is shielded by the shielding plate 4o fixed to the mounting plate 39 with the fixing screws 44. This shielding allows the damper 38
When it opens to the solid line position in Fig. 1, the indoor suction port 27 opens.
Most of the indoor air that has entered the room passes through the indoor blower 26, the indoor heat exchanger 26, and is blown out from the indoor air outlet 28, but some air flows through the upper opening 36a as shown by arrow A. It flows into the outdoor unit part 36, flows into the outdoor air supply port 33, passes through the outdoor heat exchanger 31 by the outdoor blower 32, and is exhausted together with the outdoor air blown out from the outdoor air outlet 34. Configure as a product.

Next, if there is a request from the user for an air supply specification product, as shown in Figure 2, take out the indoor blower 26 from the indoor unit section 29 side, remove the fixing screws 44, and cover the Reverse the plate 4o and install it facing upward. That is, by fixing the long piece of the L-shaped shielding plate 40 upward with the fixing screw 44 and then fixing the indoor blower 26, the upper opening 36a of the partition plate 3o is shielded.

As a result, when the damper 38 is opened to the solid line position in FIG. Although it is blown out from the outlet 34 to the outdoors, some of the air flows through the lower opening 36b to the indoor unit section 29 as shown by arrow B in FIG. Air is supplied together with indoor air that passes through the exchanger 26 and is blown out from the indoor air outlet 28, and is configured as an air supply specification product.

As a result, it is possible to select between an exhaust specification product and an air supply specification product using the single wall penetrating individual air conditioner 21 even after installation.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, a partition plate is provided between the indoor unit section and the outdoor unit section, and an opening is provided in the partition plate. Since a shielding plate was installed on the indoor blower side with dampers on both wings to close either the opening above or below the center of the opening, the indoor blower could be attached and removed from the indoor side and the shielding plate could be installed. By simply changing the mounting direction of the plates, a single individual air conditioner can be used for either exhaust or supply air. Therefore, when it becomes necessary to change the specifications of a building or other building due to changes in the environment, it is easy to adapt to either specification on-site, and furthermore, changes can be easily made even after the installation is complete. It exhibits effects such as:
