Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an air conditioner that is incorporated into partition furniture or the like to air condition two rooms.

[Background technology]

When heating and cooling a living room, it is more efficient to blow cold air from the top and hot air from the bottom. However, conventional furniture built-in air conditioners are built into the upper or lower part of the furniture, resulting in poor heating or cooling efficiency.

Furthermore, conventionally, when air-conditioning two rooms, a separate air conditioner is installed in each room, which poses a problem of high cost. Therefore, we came up with the idea of storing it in a partition furniture and using a single air conditioner to air condition the rooms on both sides. However, if an air conditioner is manufactured exclusively for two rooms, there are problems in that the number of models increases, production efficiency decreases, and inventory management is inconvenient.

[Purpose of the invention]

This invention provides an air conditioner that can perform both heating and cooling efficiently, can be used for two rooms or one room depending on whether or not an adapter is attached, and can improve productivity by standardizing parts. The purpose is to

[Disclosure of the invention]

The air conditioner of the present invention includes a main rise duct having an upper entrance and a lower entrance at the upper and lower sides of the front, a first air passage through which the main rise duct is opened to the upper entrance, and a second air passage through which the main rise duct is opened to the lower entrance. a partition wall that partitions the main upright duct into two; an air conditioner main body that protrudes from the lower side of the main rising duct and houses a blower means and a heating and cooling means; an air path switching device connected to the first air path and the second air path; and an air path switching device provided along the back side of the main rising duct and partitioned internally into an upper air path and a lower air path, and the upper air path and a separate room air-conditioning adapter having an upper separate room entrance and exit and a lower separate room entrance that open to a lower air passage; The adapter includes a first adapter communication section and a second adapter communication section that communicate with the air path.

According to the structure of the present invention, since a separate room air conditioning adapter is provided on the back side of the main rising duct and communicates with this main rising duct, two rooms can be air-conditioned simultaneously by one unit. Furthermore, if a separate room air conditioning adapter is not attached, it can be used as an air conditioner for one room. Therefore, productivity can be improved by standardizing parts.

In addition, an upper entrance and a lower entrance are provided above and below the main rising duct, and the inlet and outlet of the air conditioner main body can be switched to the first and second air paths opened to the upper and lower entrances, respectively. Since it is connected to the air conditioner, cold air can be blown from the upper entrance and warm air can be blown from the lower entrance. Therefore, both heating and cooling can be performed efficiently.

Furthermore, the inside of the separate room air conditioning adapter is partitioned into an upper air passage and a lower air passage, each of which is communicated with the first air passage and the second air passage of the main rising duct, and an upper separate room entrance and a lower separate room entrance are provided. The room on the side of the separate air conditioning adapter can be both heated and cooled efficiently, just like the room on the main rising duct side.

Furthermore, since the main rising duct extending vertically and the separate room air conditioning adapter are located in front and behind each other, and the air conditioner main body protrudes from the lower side of the main rising duct, it is possible, for example, to partition the main rising duct and the separate room air conditioning adapter. Install it in the gap between furniture,

The front surface of the lower air passage 105 is closed by the back surface of the main rising duct 3 and the air conditioner main body 9, and communicates with the second adapter communication section 102 of the main rising duct 3 through a horizontal communication duct 108. The horizontal communication duct 108 is integrally attached to the separate room air conditioning adapter 100, and is connected to the second communication section connection port 109.
and a lower air passage communication port 110.

As shown in FIGS. 4 and 5, the air conditioner main body 9 houses a heating and cooling means 8 and a blowing means 7,
It also includes an air path switching device 12 that switches the suction port 11 and the air outlet 10 to each other and connects the first air path 4 and the second air path 5. Air conditioner body 9
A blowing chamber 9b is provided above the main chamber 9a that accommodates the blowing means 7 and the heat exchange means 8 through a horizontal partition plate 14 (see FIG. 5), and a filter 15 is installed on the rising duct 3 side of the main chamber 9a. A suction chamber 9c is provided through the suction chamber 9c. The air blowing means 7 is composed of a fan such as a Sirotskov fan, and a fan case outlet 7a thereof opens into the horizontal partition plate 14. Heating and cooling means 8
consists of a heat exchanger 8a interposed between the filter 15 and the blowing means 7, and a heat medium heating and cooling device (not shown) such as a heat pump type that circulates a heat medium through the heat exchanger 8a.

The blowout chamber 9b and the suction port 9c communicate with each other through a switching chamber 9d, and the blowout port 10 and the suction port 11 of the air conditioner body 9 are formed by opening the blowout chamber 9b and the suction chamber 9c into the switching chamber 9d.

The switching chamber 9d is divided into two in the front and back by a vertical partition plate 16 following the partition wall 6 of the rising duct 3, and a first damper 17 and a second damper 18 are provided in each divided switching chamber. The first damper 17 and the second damper 18 are each rotatably supported at their base ends, and are connected to the air outlet 10 at a vertical angle and to the air inlet 1 at a horizontal angle.

(b) Cooling or heating only the second room 202, (c) Both rooms 20
1,202 can be operated in three modes: cooling or heating at the same time.

In this way, both rooms 201 and 202 are heated and cooled, but the cold air is sent to the upper entrance and the upper separate room entrance.
Since the hot air is blown out from the lower entrance/exit 2 and the lower separate room entrance/exit 107, efficient air conditioning can be obtained both during cooling and heating. That is,
Efficient heating and cooling can be achieved by utilizing the temperature distribution in the room (heating air accumulates at the top and cold air accumulates at the bottom).
In addition, the overall thermal circulation in the room can be improved.

In addition, in the air conditioner having this configuration, the main rise duct 3 extending vertically and the separate room air conditioning adapter 100 are located in front and behind each other, and the air conditioner main body 9 is made to protrude from the lower side surface of the main rise duct 3.

Since the air conditioner of the present invention is provided with a separate room air conditioning adapter that communicates with the main rise duct on the back of the main rise duct, one unit can air condition two rooms at the same time. Furthermore, if a separate room air conditioning adapter is not attached, it can be used as an air conditioner for one room. Therefore, productivity can be improved by standardizing parts.

In addition, an upper entrance and a lower entrance are provided above and below the main rising duct, and the inlet and outlet of the air conditioner body can be switched to the first and second air passages opened to the upper and lower entrances, respectively. Since it is connected to the air conditioner, cold air can be blown from the upper entrance and warm air can be blown from the lower entrance. Therefore, both heating and cooling can be performed efficiently.

Furthermore, the inside of the separate room air conditioning adapter is partitioned into an upper air passage and a lower air passage, each of which is communicated with the first air passage and the second air passage of the main rising duct, and an upper separate room entrance and a lower separate room entrance are provided. The room on the side of the separate air conditioning adapter can be both heated and cooled efficiently, just like the room on the main rising duct side.

Furthermore, since the main rising duct extending vertically and the separate room air conditioning adapter are located in front and behind each other, and the main body of the air conditioner protrudes from the lower side of the main rising duct, for example, the main rising duct and the separate room air conditioning adapter It can be installed in the gap between partition furniture, and the air conditioner main body can be stored in the partition furniture, which has the effect of fitting well with the furniture.
