Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an improvement in the structure of a dehumidifier with a cooling function.

<Prior Art> One type of dehumidifier has a cooling function. However, in the conventional dehumidifier with cooling function, as shown in Figs. It is cooled by the evaporator 5, and the moisture in the air is condensed to perform dehumidification. Dry cold air is fan 4b
The air is sent to the condenser 6 side, heated by the condenser 6, becomes room temperature air, and is sent out from the air outlet 7 to the outside of the main body. Water droplets condensed by the evaporator 5 are collected in a drainage container 8. The drainage container 8 is installed below the evaporator 5 and directly below the drainage tray 9,
The water can be taken out from the drainage container outlet 10 and the accumulated water can be thrown away. The electric motor 3 and the fan 4 are installed on the partition plate 11 so that the direction of air flow is horizontal.
In addition, the refrigerant used in the evaporator 5 and condenser 6 is expanded and heat-absorbed in the evaporator 5 by the compressor 12 installed at the inner bottom of the main body box 1, and is condensed and heat-radiated in the condenser 6. The compressor 12 is reached.
This is the so-called refrigeration cycle. Compressor 12
is installed in the lower part of the main body box 1. Furthermore, two openings 13a, 13 are provided in the upper top plate 13 of the main body box 1.
b, and an opening/closing plate 14 and an insertion plate 15 are attached to them, respectively. The opening/closing plate 14 has one end rotatably fixed to the periphery of the opening 13a by a hinge or the like, and can perform opening/closing operations like a door. The insertion plate 15 has the opening 13
It is slidably attached and detached so as to cover the area b. During dehumidification, the openings 13a and 13b are closed by the opening/closing plate 14 and the insertion plate 15, respectively, and the air sucked into the machine from the suction port 2 passes through the evaporator 5, fans 4a and 4b, and condenser 6. It is adapted to be sent out from the air outlet 7. Next, when performing dehumidification and cooling at the same time, the opening/closing plate 14 is opened, and the insertion plate 15 is removed from the opening 13b of the top plate 13, so as to close the gap 11a between the electric motor 3 on the partition plate 11 and the top plate 13. Partition plate 11 and top plate 13
Insert/attach between. As a result, the air taken in through the intake port 2 is cooled through the evaporator 5 and becomes cold, dry air, which is then transferred to the main body box.
The fan 4 exits the machine from the opening 13a of the upper top plate 13.
Sent by a. Also, air from outside the machine flows in through the opening 13b from which the insertion plate 15 is removed by the fan 4b, cools the condenser 6, and is sent out from the air outlet 7.

With the above configuration, when dehumidifying only, the air after dehumidification is sent out in only one direction, so care must be taken not to block the air outlet during installation, and the indoor air In order to increase circulation efficiency, it was necessary to consider the interior layout and the location of the dehumidifier. Furthermore, switching between dehumidifying only and dehumidifying and cooling at the same time requires opening the opening/closing plate 14 or changing the installation position of the insertion plate 15, making the operation somewhat difficult. In addition, since the openings 13a and 13b are provided on the outer surface of the upper top plate 13 of the main body box 1, the openings 13a and 13b are unsightly, and dust and dirt can easily enter, which has been a problem.

<Purpose of the invention> The present invention focuses on the above-mentioned drawbacks and aims to improve these various problems.

<Structure of the invention> The dehumidifier of the invention comprises an air passage, an opening/closing plate, a switching lever, and an air outlet in the upper part of a main body box containing an evaporator, a condenser, a compressor, a motor fan, a drainage container, etc.

<Example> FIGS. 3 and 4 show longitudinal sectional views of an example of the dehumidifier of the present invention. The evaporator 5 and condenser 6 provided in the upper part of the main body box are covered by casings 16a and 16b, respectively, and the space between the two casings, that is, the upper part of the main body box is partitioned by a partition plate 11 in the center. There is. An electric motor 3 is attached to the partition plate, and fans 4a and 4b are provided on both sides of the electric motor 3, facing the evaporator side and the condenser side, respectively. Further, an opening/closing plate 14 and a switching lever 14a are installed above between both casings so as to be able to come into contact with and separate from the partition plate 11, respectively. Furthermore, air passages 17a and 17b are provided in the upper part of the main body box 1 between the top plate 13 and the casings 16a and 16b, respectively, and are configured to be openable and closable by the opening and closing plate 14. FIG. 5 shows an example of the shape and configuration of the opening/closing plate 14 in an enlarged exploded manner. The opening/closing plate 1
4 is rotatably connected to the switching lever 14a via a connecting rod 14b. The connection between the opening and closing plate 14 and the connecting rod 14b is achieved by fitting an engaging protrusion 14f provided at one end of the connecting rod 14d into an engaging hole 14e in the side wall of the locking hole 14d provided in the opening and closing plate 14. , measures are taken to prevent air from leaking from the locking hole 14d. Next, switch lever 1
4a and the connecting rod 14b are connected by the switching lever 14.
The engagement hole 14g provided at one end of a and the connecting rod 14
The engagement hole 14h provided at one end of b is connected to the rotation shaft 1.
4c, it is rotatably attached.

<Function> With the above-described structure, the dehumidifier of the present invention allows, during dehumidification, as shown in FIG. It flows upward along the partition plate 11 and is sent out of the machine from the air outlet 7c provided in the opening of the top plate 13 of the main body box. At this time, the opening/closing plate 14 is held vertically, that is, in close contact with the casings 16a, 16b, so as to close the passages 17a, 17b. Also, the air sucked in from the suction port 2b passes through the condenser 6 surrounded by the casing 16b, and is sent to the upper air outlet 7 by the fan 4b.
It is sent out of the aircraft from c. As a result, the cold dry air cooled and dehumidified by the evaporator 5,
It is mixed with warm air heated by the condenser 6,
This will circulate the room as dry air that is close to room temperature.

Next, when performing dehumidification and cooling at the same time, as shown in FIG. 4, pull up the switching lever 14a and move the opening/closing plate 14 to close the air outlet 7c and allow air to flow into the air passages 17a and 17b. do. The air sucked in through the suction port 2a is cooled and dehumidified through the evaporator 5, and becomes cold, dry air, which is then sent out of the machine from the air outlet 7a through the air passage 17a. Also, the air sucked in from the suction port 2b is heated through the condenser 6, becomes warm air, and passes through the air passage 17b to the air outlet 7b.
sent out of the aircraft. In this way, since cold dry air and warm air are sent out in opposite directions from separate outlets, it is possible to perform cooling as well as dehumidification.

<Effects of the invention> The dehumidifier of the invention can be easily operated by moving the switching lever 14a up and down to open and close the opening/closing plate that comes into contact with and separates from the partition plate that partitions the evaporator side and the condenser side in the main body box. The flow direction of dehumidification and warm air can be controlled, and when dehumidification and cooling are performed at the same time, cold air and warm air are sent out from opposite directions.
The indoor air circulation efficiency is improved, and highly efficient dehumidification and cooling can be performed.
