The present invention relates to a dehumidifier, and more particularly, to a desiccant dehumidifier. More particularly, the present invention relates to a desiccant dehumidifier in which the installation state of the desiccant dehumidifier can be changed as desired by the user, and the internal configuration of the desiccant dehumidifier can be simplified and manufactured smaller.

A typical desiccant dehumidifier is a dehumidifier that absorbs moisture in the air at room temperature and uses the property of an absorbent material in which moisture is evaporated when heat is applied. Specifically, the moisture absorbent material is manufactured in the form of a roller, and moisture is absorbed in a portion of the desiccant roller which is placed at a predetermined position during the operation of causing the desiccant roller to rotate, and in another portion of the desiccant roller which is placed at another position. It is a home appliance that allows moisture to evaporate, thereby removing internal moisture of the system.

The desiccant dehumidifier may be divided into a wall-hung type used by hanging on a wall and a floor-mounted type used by being placed on an indoor floor. In addition, there is a difference in the structure and handling of the condensate drainage according to the form of the desiccant dehumidifier, the wall-hanging type to make the air containing the moisture to be directly exhausted by drilling a hole in the wall while the dehumidifier is mounted on the wall, the floor In the stationary type, a separate condensate tray is further formed on the bottom of the desiccant dehumidifier, and when the condensate is collected at a predetermined level, the condensate tray is removed to discard the condensate.

However, depending on the indoor environment and humidity conditions and the user's preference, the user may wish to use the dehumidifier on a wall in some cases, and in some cases, to use it on the floor. Therefore, although a dehumidifier having a variable installation state is required even for the same dehumidifier, no dehumidifier structure capable of meeting such a demand has been introduced.

In addition, the desiccant dehumidifier, together with the desiccant roller, a heat-generating heater, a condenser to allow moisture containing air to be condensed by external air, and hot air passing through the condenser and the hot part of the desiccant The heat exchanger performs heat exchange by contacting the hot air by passing heat through it, the condensate receiver for receiving condensate, the regenerative blower to which the air volume is applied in the direction of removing moisture, and the internal air of the system. A dehumidifier blower is included to force inflow / outflow. In particular, air is forcedly flowed by the regenerative blower and the dehumidification blower, so that moisture in the air is transferred to the desiccant roller or the desiccant roller is dried.

However, the conventional desiccant dehumidifier has a disadvantage in that the internal structure of the dehumidifier is complicated and heavy because the regenerative blower and the dehumidification blower are driven by separate driving motors.

The present invention is proposed to solve the above problems, and an object of the present invention is to propose a dehumidifier capable of more actively satisfying a user's preference by allowing the installation state of the dehumidifier to be changed to a state desired by the user.

In addition, it is an object of the present invention to propose a dehumidifier in which the air flow inside the dehumidifier is performed by a single fan motor, where the configuration of the dehumidifier can be made smaller and lighter.

The dehumidifier according to the present invention for achieving the above object is a dehumidifier body; A dehumidification roller provided in the dehumidifier body; A regeneration flow path through which the air to be moistened passes through the first region of the dehumidification roller; A condenser in which moisture is condensed in the air flowing through the regeneration flow path; A suction passage through which the dehumidified air flows through the second region of the dehumidification roller; A heat exchanger in which air passing through the suction passage and air flowing into the first region exchange with each other; A regenerative blower for blowing air to the first region; A dehumidifying blower for blowing air to the second area; A condensate receiver selectively coupled to one side of the dehumidifier body to collect condensate generated by the condenser; And a plurality of flow paths formed at an outlet end of the condenser and an inlet end of the heat exchanger.

According to another aspect of the present invention, a dehumidifier includes: a dehumidifying passage through which air for adding moisture to a dehumidifying roller is flown in the dehumidifier; A regeneration flow path for removing moisture from the dehumidification roller; A dehumidifying blower for forcing air to flow inside the dehumidifying passage; A regeneration blower to force air to flow in the regeneration flow path; A condensate receiver selectively mounted to the dehumidifier; And a single fan motor configured to rotate the dehumidification blower and the regeneration blower together. When the condensate receiver is installed in the dehumidifier, the regeneration flow path is operated in a closed circuit, and the condensate receiver is removed from the dehumidifier. The regeneration flow path is characterized in that it is operated in an open circuit.

According to the present invention, the installation state of the dehumidifier can be varied, and the dehumidifier can be obtained in an advantage that the size and weight can be reduced.

 Hereinafter, with reference to the drawings propose a specific embodiment of the present invention. However, the spirit of the present invention is not limited to the embodiments in which the present invention is presented, and those skilled in the art who understand the spirit of the present invention are not included in the spirit of the present invention by adding, changing, or deleting elements within the scope of the same spirit. The embodiment may be easily proposed.

1 is a structural diagram of a desiccant dehumidifier according to the spirit of the present invention.

Referring to FIG. 1, the desiccant dehumidifier according to the present invention forms an exterior of a dehumidifier and includes a dehumidifier main body 1 in which a plurality of parts are mounted, and water dehumidified in the dehumidifier is located at a lower side of the dehumidifier main body 1. There is a condensate receiver (2) to be collected. The condensate receiver 2 is a part which is selectively mounted with respect to the dehumidifier main body 1, and when the dehumidifier main body 1 is installed by the wall, it is removed from the dehumidifier main body 1, and the dehumidifier main body 1 is bottom-mounted. When installed, it is mounted to the dehumidifier main body 1 to collect the condensate.

In detail, a dehumidifying roller 3 made of desiccant material is formed inside the dehumidifier main body 1 so that moisture is kept at room temperature and moisture is emitted in a high temperature atmosphere. In particular, the dehumidification roller (3) is divided into two parts, the region of the dehumidification roller is shown in the plan view of the dehumidification roller of FIG.

Referring to FIG. 2, first, a moisture absorption region 31 in which moisture is absorbed while the internal air of a system at room temperature passes, and moisture accumulated in the dehumidification roller 3 while passing through the moisture absorption region 31 are exposed to heat. It is the drying zone 32 which is evaporated by. Of course, each of the areas 31 and 32 described above is not fixed to a specific position of the dehumidification roller 3, but the dehumidification roller at the relative position where the dehumidification roller 3 is placed as the dehumidification roller 3 is rotated. (3) It is divided by function of specific part.

Air suitable for performing the functions of each region passes through each of the regions 31 and 32, and the state of the air flowing through the regions 31 and 32 will be described later.

Referring back to FIG. 1, a regeneration flow path 20 circulating inside the dehumidifier main body 1 in a closed loop and a suction flow path 8 through which internal air of a system requiring dehumidification are sucked. And a discharge passage 11 through which the air dehumidified in the dehumidifier main body 1 is discharged again into the system. The suction flow path 8 and the discharge flow path 11 may be referred to as dehumidification flow paths because the air is discharged again into the system in a state where the air inside the system is sucked and moisture is removed.

First, the operation of the dehumidifier main body 1 will be described based on the flow order of the suction flow path 8. After the low-temperature, high-humidity air is sucked through the suction channel 8, the high-temperature, high-humidity air inside the regeneration channel 20 flowing through the other conduit of the condenser 6 passes through the condenser 6. To condense. During the flow of the inside of the condenser 6 through the suction flow path 8, the latent heat of condensation is absorbed to form a state of medium temperature and high humidity.

The air passing through the condenser 6 passes through the moisture absorption zone 31 of the dehumidification roller 3 to remove moisture, and the state is in a medium temperature and low humidity state. The air flows into the heat exchanger 7 to perform heat exchange to deprive heat. After the temperature is further lowered, the air is discharged into the system via the dehumidifying blower 10 and the discharge passage 11. The dehumidifying blower 10 will easily guess a negative pressure atmosphere in which air flows into the dehumidifier main body 1 from the inside of the system.

In addition, the operation of the dehumidifier main body 1 will be described sequentially with respect to the air circulating inside the dehumidifier main body 1 through the regeneration flow path 20. While passing through the heat exchanger 7, heat is absorbed to form air of medium temperature and low humidity to be guided to the regenerative blower 4. The medium-temperature and low-humidity air blown through the regenerative blower (4) is formed in an atmosphere of high temperature and low humidity while passing through the heater (5), and then flows into the drying area (32) of the dehumidification roller (3) so that moisture of desiccant Allow to evaporate into the air. Then, the air passing through the dehumidification roller (3) is changed into a state of high temperature and high humidity and flows into the condenser (6). While passing through the drying area 32, latent heat of moisture is absorbed and heat inside the drying area 32 is absorbed.

During the passage of the condenser 6, heat exchange with low-temperature, high-humidity air in the suction channel 8 is performed to condense. Therefore, moisture is taken away and changed into the state of low temperature and low humidity before entering the heat exchanger 7.

The low temperature and low humidity air delivered to the heat exchanger 7 is exchanged with the medium and low humidity air of the suction flow path 8 passing through the heat exchanger 7 to be converted into the air of the medium and low humidity, and then regenerated blower again. Flows into (4).

In addition, in the present invention, the condensate receiver 2 may be separated, so that the dehumidified water may be conveniently removed to the outside. The condensate receiver 2 may be used when the dehumidifier main body 1 is used as a bottom type. It is used to collect condensate. And, when the dehumidifier is used as a wall-hung type to be removed from the dehumidifier body (1).

In particular, in the state in which the condensate receiver 2 is removed, water and air condensed in the condenser 6 are discharged to the outside and the air in the room is directly introduced into the dehumidifier. As a result, when the condensate receiver 2 is removed and the dehumidifier is used as a wall-mounted type, the regeneration flow path 20 is operated in an open circuit, and the regeneration channel is mounted when the condensate receiver 2 is mounted and the dehumidifier is used as a bottom type. 20 is operated in a closed circuit.

When the condensate receiver 2 as shown is fixed to the dehumidifier main body 1 and separated, a separate structure is further required to operate the dehumidifier. In particular, a flow path through which the condenser 6 and the heat exchanger 7 are interconnected will vary. This will be described in detail below.

First, the regeneration-side discharge passage discharged from the condenser 6 has a first regeneration-side discharge passage 21 and a second regeneration-side discharge passage in order to change the connection state depending on whether the condensate receiver 2 is coupled. 22) are formed respectively. The first regeneration-side discharge passage 21 is a passage through which the condensed water and air condensed in the condenser 6 are discharged to the outside through the wall (see 29 in FIG. 4) as a whole when the condensate receiver 2 is removed. The second regeneration-side discharge passage 22 is a passage for allowing the water condensed in the condenser 6 to fall into the condensate receiver 5 while the condensate receiver 2 is mounted.

In addition, a first switch 12 connected to the condensate receiver 2 is further formed in order to change the conduit state of the regeneration-side discharge passages 21 and 22 according to whether the condensate receiver 2 is mounted. . When the condensate receiver 2 is mounted by the first switch 12, the first regeneration-side discharge passage 21 is blocked.

In addition, the regeneration side suction flow path flowing into the heat exchanger 7 includes the first regeneration side suction flow path 23 and the second regeneration side suction in order to change the connection state depending on whether the condensate receiver 2 is coupled. Flow paths 24 are formed, respectively.

The first regeneration side suction flow path 23 is a flow path through which air flows when the indoor air is directly sucked into the heat exchanger 7 while the condensate receiver 2 is removed. In addition, the second regeneration-side suction passage 24 is a passage for allowing air condensed in the condenser 6 to remove moisture from the condenser 6 while the condensate receiver 2 is mounted. In addition, the second switch 13 and the second switch 13 is connected to the condensate receiver (2) in order to change the pipeline state of the regeneration-side suction flow paths (23) and (24) depending on whether the condensate receiver (2) is mounted. Three switches 14 are further formed.

The second switch 13 is operated so that the valve 25 is opened when the condensate receiver 2 is mounted so that the second regeneration side suction passage 24 is opened. Of course, when the condensate receiver 2 is removed, the second switch 13 acts to close the valve 25 so that the second regeneration side suction passage 24 is closed. In addition, when the condensate receiver 2 is removed, the third switch 14 opens the first regeneration-side suction passage 23 so that the internal air of the system requiring dehumidification flows directly into the heat exchanger 7. Be sure to

On the other hand, the dehumidifying blower 10 and the regenerative blower 4 are combined with a rotating shaft 27 extending from a single fan motor 28. Therefore, when the operation of the dehumidifier starts and the fan motor 28 is rotated, the dehumidification blower 10 and the regeneration blower 4 are rotated together. As such, the regenerative blower 4 and the dehumidification blower 10 are operated by a single fan motor 28 so that the space required for installing one fan motor is not required, and the size of the dehumidifier can be reduced. You can get the advantages.

In addition, the position on the flow path in which the blowers 10 and 4 can be placed is not limited to the position as shown in the drawing, and may be formed anywhere as long as air can stably flow in the flow path inside the dehumidifier. have. For example, the blowers 10 and 4 are formed immediately before the air is sucked into the heat exchanger 7, thereby allowing the air to be forcedly blown.

Figure 3 shows the flow path structure when the dehumidifier according to the present invention is installed in a bottom mounting type, Figure 4 shows the flow path structure when it is installed in a wall-hung type. In these figures, only the case where the fluid flows through the inside of the flow path is shown, and when the fluid does not flow, the illustration is omitted simply.

Referring to Fig. 3, when the dehumidifier is installed in the bottom type, the condensate receiver 2 is mounted. At this time, the first regeneration-side discharge passage 21 is closed by the first switch 12, and condensed water drops through the second regeneration-side discharge passage 22. In addition, since the second regeneration side suction passage 24 is opened by the second switch 12 and the valve 25, and the first regeneration side suction passage 23 is closed by the third switch 14, The air from which the condensed water is removed by the condenser 6 flows into the heat exchanger 7.

As a result, since the condenser 6 and the heat exchanger 7 are connected by a predetermined flow path, the regeneration flow path 20 is eventually operated in a closed circuit.

Referring to Fig. 4, when the dehumidifier is installed in a wall-mounted type, the condensate receiver 2 is removed. At this time, the first regeneration-side discharge passage 22 is opened by the first switch 12, and condensed water and air are discharged through the first regeneration-side discharge passage 21. Of course, the condensed water and air flowing through the first regeneration-side discharge passage 21 pass through the wall surface 29 and are discharged directly to the outside. Since the second regeneration side suction passage 24 is closed by the second switch 12 and the valve 25, and the first regeneration side suction passage 23 is opened by the third switch 14, The internal air of the system flows directly into the heat exchanger (7).

At this time, the condenser 6 and the heat exchanger 7 are not connected to each other, and the internal air of the system is introduced into the heat exchanger 7, and the air inside the dehumidifier is discharged to the outside by the condenser 6. The regeneration flow path 20 is eventually operated in an open circuit.

When the dehumidifier is installed as a wall-mounted as described above, there is an advantage that the user's convenience is improved because the user does not need to empty the condensed water at regular intervals.

5 is a view showing another embodiment according to the spirit of the present invention.

Referring to FIG. 5, the present embodiment is mostly the same as the other embodiments described above, except that the positional relationship between the dehumidifying blower 10, the regenerative blower 4, and the fan motor 28 is different. There is only a difference. In detail, in one embodiment, the dehumidifying blower 10 and the regenerative blower 4 are formed on both sides of the fan motor. The dehumidification blower 10 and the regeneration blower 4 are connected.

In such a configuration, since the blowers 4 and 10 are connected to the fan motor 28, the degree of freedom in arrangement of the fan motor 28 and the blowers 4 and 10 is further increased, and the dehumidifier space The internal configuration of the dehumidifier can be obtained in various configurations depending on the shape and arrangement can be obtained.

By the desiccant dehumidifier as proposed, since the dehumidifier of the same mechanism can be installed in a wall-hung or floor mounted type, the user's convenience can be improved.                     

In addition, since the fan inside the dehumidifier can be driven by a single fan motor, there is an advantage that the internal configuration of the dehumidifier can be configured to be more compact and lighter.
