Description

[Detailed Description of the Invention] The present invention relates to a dehumidifier equipped with an electric air cleaning device.

A conventional dehumidifier will be explained with reference to FIG.

Reference numeral 1 denotes a housing, which has an air suction port 1a and a discharge port 1b formed at the upper portions of both sides.

A flexible porous air filter 2 is attached along the suction port 1a.

3 is an evaporator, 4 is a propeller fan, 5 is a fan motor,
6 is a condenser, which is arranged in this order.

Reference numeral 7 denotes a dew pan, which is placed directly below the evaporator 3.

8 is a dew storage tank, and 9 is a compressor. As is well known, when the compressor 9 is operated, the evaporator 3 becomes low temperature and the condenser 6
becomes high temperature and dehumidifies the moisture in the indoor air sent by the rotation of the propeller fan 4.

In this case, when the indoor air passes through the air filter 2, dust is removed.

However, simply placing the flexible porous air filter 2 in the ventilation path makes it difficult to remove fine dust, soot, cigarette smoke, bacteria, viruses, lumps, and the like.

For this reason, it is conceivable to incorporate an electric air purifier into a dehumidifier, but improvements in safety and dust removal efficiency are strongly desired.

The present invention has been made based on this point.

In other words, in a dehumidifier that has a refrigeration cycle consisting of an evaporator, a compressor, etc. inside the housing, and also has an air blower such as a fan and a fan motor, the evaporator, condenser, and fan are The above-mentioned requirements are satisfied by arranging the electrostatic precipitators in sequence and by arranging an electrostatic precipitator charged at a high voltage in the gap between the condenser and the fan.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

Reference numeral 10 denotes a synthetic resin casing, which has opposing grill-shaped air intake Oa and air discharge ports 10b formed on the upper sides of both sides.

Reference numeral 11 denotes a Saran net air filter, which is arranged along the inside of the air suction port 10a.

12 is an evaporator, and 13 is a condenser, which are arranged in parallel.

A propeller fan 14 is directly connected to a fan motor 15.

Then, the evaporator 12. Condenser 13
．． A propeller fan 14 and a fan motor 15 are arranged in this order.

16 is an electric type electric purifier, and an insulator 1 is attached to the mounting frame 16a.
6b, the electrostatic precipitator 16C is installed in the gap between the condenser 13 and the propeller fan 14 through the opening 10C' provided on the upper surface of the case 10, and It is provided so that it can be attached and detached freely.

17 is a high voltage generator, and 30
A high voltage of about 00 to 5000 V is supplied.

18 is a micro switch, and a push rod 18 is attached to the top surface of the housing 10.
A protrudes and is set so as to close the power supply circuit of the high pressure generator 17 when the electric air purifier 16 is attached.

Reference numeral 19 denotes a dew pan, which is placed directly below the evaporator 12.

20 is a bag storage tank, and 21 is a compressor.

Therefore, during dehumidification operation, the compressor 21 and fan motor 15
to be energized.

Therefore, the evaporator 12, which together with the compressor 21 constitutes a refrigeration cycle, becomes low temperature, the condenser 13 becomes high temperature, and the fan 14 rotates to circulate the indoor air as shown by the solid line arrow.

Therefore, the indoor air is first removed from large particles by the air filter 11, then cooled and dehumidified by the evaporator 12, and then returned to the original room temperature by the condenser 13 to perform the same dehumidifying operation as before.

Next, in normal dehumidifying operation, the compressor 21 is not energized, but the fan motor 15 and the high pressure generator 17 are energized, so that the electrostatic precipitator 16C is charged to a high voltage, and the indoor air is Therefore, it circulates as shown by the solid line arrow.

Therefore, large dust particles are first removed from the indoor air by the air filter 11, and then fine dust, soot, and cigarette smoke are removed by the electrostatic precipitator 16C.

Since bacteria, viruses, dust, etc. are removed, the room can be kept sanitary.

According to the present invention, the electrostatic precipitator 16C is charged to a high voltage.
Since it is housed in the gap between the condenser 13 and the propeller fan 14, there is no risk of electric shock from inserting a hand or the like from the outside, making it extremely safe.

Furthermore, during electrohumidification, dehumidification operation and dust removal operation can be performed at the same time, but in this case, the dry air after dehumidification is transferred to the electrostatic precipitator 16.
Since the dust is removed by C, the dust removal efficiency is high.

According to this embodiment, the electrostatic precipitator 16C is detachably attached to the casing 10, and the microswitch 18, which is opened and closed by this attachment and detachment, is connected to the power circuit of the electrostatic precipitator 16C, which further improves safety. can be increased.

Moreover, since the electrostatic precipitator 16C is composed of a metal charged body 16d connected to the high-pressure generator 17 and a porous synthetic resin charged body 16e that is in contact with the metal charged body 16d and has flexibility, The charged resin body 16e can be removed and cleaned.

As explained above, according to the present invention, it is possible to provide a dehumidifier with an air purifying device that is highly safe and highly efficient in removing dust.
