Abstract

PURPOSE:To make a small-sized main body by a method wherein an evaporator and a condensor are integrally bent into a dogleg-shape, a heat exchanger and a drain pipe for the condensor are eliminated. CONSTITUTION:An evaporator 5 and a condensor 6 are connected by an end plate 5a having a dogleg-shape and integrally formed to each other. Indoor air sucked from an indoor air suction port 7 at a front surface passes through the evaporator 5, thereafter the air is supplied by an indoor fan 4a from an indoor air blowing port 8 at a front surface into a room as a cold air. In turn, outdoor air sucked from an outdoor suction port 9 at a rear surface passes through the condensor 6, thereafter the air is discharged as hot air from the outdoor blowing port 10 at a rear surface out of the room by an outdoor fan 4b. Condensed water at the fins of the evaporator 5 is accumulated in a lower water pan 11. The accumulated condensed water passes through a small hole 14, drips onto an upper end of the condensor 6, the water is evaporated again by heat from the condensor 6 and blown out of the room. Accordingly, the water pipe is not required. Since the part of the condensor 6 of the heat exchanger is slightly inclined from a horizontal plane, its vertical sizes can be reduced while keeping an aeration area.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides an integrated sirocco fan having a fan section for an indoor ventilation circuit, a fan section for an outdoor ventilation circuit, an evaporator section and a condenser section. The present invention relates to an integrated air conditioner in which an indoor ventilation duct and an outdoor ventilation duct are configured by an integrated heat exchanger.

2. Description of the Related Art Conventionally, this type of integrated air conditioner has a structure as shown in FIGS. 6 and 7.

That is, in the same figure, 101 is an integrated air 2...-
- The main body of the harmonizer (hereinafter referred to as the main body), 102 is a partition plate made of a heat insulating material, 103 is a through hole provided in the partition plate 102, 104 is a sirocco fan, 105 is an evaporator, 106 is a condenser, 107 108 is an indoor air inlet, 109 is an outdoor air inlet, 110 is an outdoor air outlet, 11
1 is a fan motor, and 112 is a compressor.

The flow of air in the integrated air conditioner configured as above will be explained.

Indoor air sucked in from the indoor suction port 107 provided on the front surface of the main body 101 passes through the evaporator 105 and then passes through the upper part of the sirocco fan 104, that is, the indoor fan section 1.
04a, cool air is supplied into the room from the indoor air outlet 108 provided on the front surface of the main body 10'1.

On the other hand, outdoor air sucked in from the outdoor side suction port 109 on the back side of the main body 101 passes through the condenser 106 and is then connected to the outdoor side outlet provided on the back side of the main body 101 by the lower part of the sirocco fan 104, that is, the outdoor side fan section 104b. 110
Warm air is then exhausted to the outside at a rate of 3 hepates.

Next, condensed water will be explained. The condensed water is sent to the evaporator 105
The water is collected in a water tray 113 installed at the bottom of the room, and then drained outside through a drainage pipe 114.

Problems to be Solved by the Invention However, in the above configuration, there are two heat exchangers, an evaporator and a condenser, and a drainage pipe is required for treating condensed water, which increases the cost. There was a problem.

Means for Solving the Problems In order to solve the above problems, the present invention configures a heat exchanger fan section that connects the evaporator and the condenser with a dogleg-shaped end plate, and connects the evaporator section to the condenser section. A water receptacle having a plurality of small holes and having heat insulating properties is provided above the vessel part and between the evaporator part and the condenser part.

For production The effects of the above configuration are as follows.

Condensed water generated on the surface of the evaporator section travels through the fins of the evaporator section and collects in the water tray. After that, the water passes through a small hole provided in the water tray, drips into the condenser section, is evaporated by the heat of the condenser, and is discharged outside.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4 of the accompanying drawings.

In the figure, 1 is an integrated air conditioner main body (hereinafter referred to as the main body), 2 is a partition plate made of heat insulating material, 3 is a through hole provided in the partition plate 2, 4 is a sirocco fan, and 5 is an evaporator. vessel,
6 is a condenser, 7 is an indoor suction port, 8 is an indoor air outlet, 9
10 is an outdoor air outlet, 11 is a water tray,
12 is a fan motor, and 13 is a compressor. As shown in FIG. 2, the evaporator 5 and condenser 6 have a dogleg shaped end plate 5a
are connected to form an integrated structure. As shown in FIG. 3, there is a water tray 11 below the evaporator 5, and the condenser 6 is installed in the main body 1 so that the upper end of the condenser 6 is below the water tray 11.

The flow of air in the integrated air conditioner configured as above will be explained.

After passing through the evaporator 5, the indoor air sucked in from the indoor suction lower provided on the front surface of the main body 1 is sent to the main body 1 by the upper part of the sirocco fan 4, that is, the indoor fan section 4a.
Cool air is supplied into the room from an indoor air outlet 8 provided on the front surface of the room. - Outdoor air sucked in from the outdoor side suction port 9 provided on the back side of the blade body 1 passes through the condenser 6, and then passes through the lower part of the sirocco fan 4, that is, the outdoor side fan section 4.
An outdoor air outlet 10 provided on the back side of the main body 1 by b
The warm air is then exhausted outside.

Next, condensed water will be explained. The condensed water condensed on the fins of the evaporator 5 is collected in a water tray 11 installed below the evaporator 5.
It accumulates in As shown in FIG. 4, the water tray 11 has a plurality of quadrangular pyramid-shaped depressions #11h, each of which has a small hole 14 at its bottom, so that the condensed water collected in the water tray 11 is drained from the top. It passes through the front small hole 14 and drips onto the upper end of the condenser 6. Thereafter, while flowing along the fins of the condenser 6, it is re-evaporated by the heat of the condenser 6, and is discharged outdoors together with the outdoor air.

Therefore, for condensate treatment, it was necessary to drain 6-7. Water pipes are no longer required.

Further, since the heat of vaporization of the condensed water is obtained from the condenser 6, the condensing ability is improved.
By providing a plurality of condensed water 4, condensed water can be sent to the condenser 6 evenly.

Furthermore, by adopting a dogleg-shaped heat exchanger, in this embodiment, the condenser 6 part of the heat exchanger is slightly tilted from horizontal, so while ensuring the same ventilation area as the conventional one, It is also possible to reduce the size of the main body 1 in the vertical direction.

Further, since a heat insulating material is used for the water tray 11, heat leakage near the boundary between the evaporator 5 and the condenser 6 is prevented.

Note that the shape of the depression lla provided in the water receiving tray 11 is a square pyramid shape in this embodiment, but it may be a cone shape or the like as long as it has a similar function. Further, the number of small holes 14 is not particularly limited. Further, the water tray 11 may be integrated with the partition plate 2.

Effects of the Invention As described above, the present invention provides a combination of an evaporator and a condenser.
7. By integrating the heat exchanger into one mold, the number of drain pipes for condensed water treatment can be reduced, and the main body can be made smaller, resulting in significant cost reductions. It is something that can be achieved.
