Description

Dehumidifier {Dehumidifier}

The present invention relates to a dehumidifier, and more particularly to a dehumidifier that can be used in a narrow space.

The dehumidifier is generally placed in a corner of the room, and the room air sucked from the intake port is cooled and dehumidified in an evaporator installed inside the main body, and the air dehumidified in the evaporator is reheated to a condenser to take out the room as dry air.

In addition, the dehumidifier is generally a compressor, condenser, evaporator, constituting a refrigeration cycle,

Component parts, such as an expansion valve, are accommodated inside. In the dehumidifier, moisture in the indoor air dehumidified by the evaporator is accumulated in a dehumidifying water tank disposed under the main body case, and is configured to take out and drain the dehumidifying water tank at an appropriate time.

In addition, the dehumidifier is generally formed in a shape in which an air inlet is provided in the front face, the width dimension seen from the front side is large, and the depth dimension (dimension of front and rear direction) is small.

However, in a dehumidifier with a large dimension in the width direction as seen from the front, when the dehumidifier is installed in a narrow space such as a closet or a gap between the furniture and the furniture, the intake vents face the futons and furniture in the closet. Is blocked, there is a problem that the amount of ventilation is reduced, dehumidification ability is lowered.

By solving such a problem, as in the dehumidifier described in Japanese Patent Application Laid-Open No. 2000-220867, the width of the front view of the dehumidifier is reduced, the dimensions in the front and rear directions are increased, and the intake port is increased. It is proposed to install the dehumidification water tank in the front part and the rear part, and to be able to extract from the front.

This conventional dehumidifier solves the problems of the previous dehumidifiers as described above. However, in the case of the surrounding situation, for example, when the front and rear surfaces are blocked, the intake vent is blocked and cannot be dehumidified. There is.

The present invention is devised to solve such a problem more completely, and even if any three surfaces of the front, rear, left, and right sides are blocked by obstacles such as walls or furniture, it is possible to intake into the cabin and dehumidify. It may be aimed at providing a dehumidifier.

In order to achieve the above object, the dehumidifier according to the present invention is formed to be thin and long in the front and rear direction, and the front and rear parts are moved forward or rearward as compared with the width of the middle part in the front and rear direction. A main body case having a narrow width, a blower for supplying and exhausting air, a compressor for compressing a refrigerant, an evaporator for cooling and dehumidifying the air drawn into the blower, a condenser for reheating the air dehumidified with the evaporator, A dehumidification water tank for storing moisture in the air dehumidified by the evaporator, a blowout port for discharging the air reheated by the condenser, two intake ports formed on the left and right sides of the narrow part of the main body case, The rear portion has an intake port formed from the rear side of the narrow portion to one side portion, and the evaporator, the condenser and the blower are the main body case. In terms of the side of the inlet of the narrow width portion formed in the portion that is arranged to achieve the heat in the lateral direction.

If comprised in this way, even if the surface of arbitrary three directions is blocked, inhalation to an inside of a plane can be attained and dehumidification operation can be performed. In addition, in the following description, the inlet port formed over the one side part from the back part of the narrow part in the back part of the main body case is described about the case of the inlet port formed over the right side part part from the back part of the narrow part in the main body case back part. However, when this intake port is formed from the rear side to the left side surface portion, the left and right symmetric intake is enabled, and the essence of the invention is the same. It will be described in detail below.

That is, when only the right side surface of the dehumidifier is open, the indoor air from the intake port formed in the right side surface of the narrow part in the whole body case and from the intake port formed from the rear side of the narrow part in the rear part of the body case to the right side surface part In addition, when only the left side of the dehumidifier is open, indoor air can be taken in from the intake port formed in the left side portion of the narrow portion of the main body case. In addition, when only the rear surface of the dehumidifier is open, indoor air can be taken in from the intake port formed over the left side surface portion at the rear portion of the narrow portion in the rear portion of the main body case.

In addition, when only the front side of the dehumidifier is opened, indoor air can be taken in from the two intake ports formed in the left and right side portions of the narrow portion of the entire body case.

In addition, the dehumidifying water tank may be stored in the lower portion of the main body case in the drawer type from the front.

In such a configuration, when the dehumidification water accumulated in the dehumidification water tank is drained, the dehumidification tank can be taken out directly from the front without draining the dehumidifier itself from a narrow installation place or the like, and the dehumidification water can be drained.

Moreover, the side part of a blower side among two intake ports in all of the said main body cases.

It is also possible to install an ultraviolet lamp unit disposed in all of the body cases so as to be sucked in the inlet formed in the air passage and passed before the air is sucked into the evaporator.

In this way, the intake air can be sterilized.

In addition, a louver molded in one resin can be provided in the inlet port formed from the rear surface of the narrow portion to the one side portion in the rear portion of the main body case.

If comprised in this way, two surfaces of louvers can be comprised as one continuous component. Therefore, the mold production cost and the part cost of one part can be almost omitted. In this case, since the corner portion is formed at an obtuse angle from the rear side to the one side portion, the positional fitting or attachment of the louvers integrally becomes easy.

Moreover, the louver molded integrally with the said resin can be formed in the corner part between a back side part and a side part part, and the blind plate part which does not have a louver.

If comprised in this way, the intensity | strength of a corner part can be improved.

Moreover, the connection steel of a back part and a side part in the inner surface side of the corner part formed in this shielding board part

The reinforcing rib which improves a figure may be formed integrally.

If comprised in this way, the intensity | strength of a corner part can be improved further.

Moreover, you may integrally shape the pin-shaped protrusion ring for hanging the air filter which consists of a flexible porous resin plate in the appropriate multiple places on the inner surface of the said integrally formed louver.

When comprised in this way, the air filter which consists of a flexible porous resin plate easily

It is possible to hang, and the manufacturing cost of hanging equipment becomes low.

In addition, the blower is an up-and-down blower type blower in which the housing of the half of the axial direction is called an uptake-out housing, and the housing of the other half is a downtake-out housing. It may be comprised so that it may be comprised from the upper blow-out port formed in the upper part of a main body case, and the lower blow-out port formed in the lower part of a main body case so that it may communicate with the lower take-out housing.

With this configuration, it is easy to supply dehumidified air in a desired direction by providing a plurality of blowout ports. In the above-described conventional dehumidifier (see Japanese Patent Application Laid-Open No. 2000-220867), a blowout port is formed only in the upper surface portion of the main body case, and it was difficult to supply dehumidifying air to the lower portion. The fault is solved.

The lower ejection outlet may be provided with one horizontal vane whose upper end is rotatably supported on the upper portion of the lower ejection outlet.

This configuration makes it possible to blow off dehumidifying air directly toward the bottom surface, and in particular, to improve the drying effect of the bottom surface and the like.

Moreover, you may provide one lower blade | wing with the lower end part rotationally supported by the lower outlet part below.

In this way, it becomes possible to blow dry air to the object from the bottom surface to the inclined upper direction in the horizontal direction, and can dry a wide range of objects.

In addition, the lower part of the lower outlet has an intermediate portion rotatably supported by the middle height portion of the lower outlet.

One horizontal vane may be provided. In this configuration, it is possible to directly blow out the air at an angle to the bottom surface, and also to directly blow out the dehumidifying air to the object above the inclination, and to dry a wider range of objects.
