Description

Dehumidifier {DEHUMIDIFIER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifier, and more particularly, to a dehumidifier capable of improving the regeneration efficiency by making the regeneration path of the regeneration air the shortest and making the regeneration air come into direct contact with the heating wire of the heater.

Generally, the dehumidifier causes the dehumidification rotor to circulate in the process of moisture absorption and drying regeneration by using two air paths composed of a regeneration path and a dehumidifying path.

In the dehumidifying path, the outside air is sucked into the dehumidifier by the dehumidifying fan, and when the dehumidification air passes through the desorption rotor, moisture is absorbed by the desiccant material in the desorption rotor and is changed into dry air and discharged.

At this time, the moisture absorption rotor absorbs moisture in the outside air and becomes very wet, thus affecting the re-dehumidifying effect of the moisture absorption rotor.

Therefore, the hygroscopic rotor is dried and regenerated by using the regeneration path, so that the hygroscopic rotor maintains good dehumidification performance.

In the regeneration path, the regeneration air is closed in circulation. The regeneration air at a high temperature after being heated by the heater removes the moisture of the moisture absorption rotor while passing through the moisture absorption rotor, and at the same time, It changes.

The high-temperature, high-humidity regeneration air is condensed by the condenser, and the water is liquefied and discharged, and then returned to the heater. Thus, the reproduction path is circulated.

The regeneration air enters the heater from the bottom surface of the heater case, leaves the heater again after the temperature rises, and enters the moisture absorption rotor.

In the conventional heater case, a plurality of vent holes are provided at the bottom portion, and the regeneration air enters the heating device through the vent holes and comes into contact with the heating line.

However, since the positional relationship between the plurality of ventilation holes and the heating line of the heater case is generally deviated, the regeneration air must flow through a certain distance in the heater to be in contact with the heating line.

Also, some of the air for regeneration can not make contact with the heating line at all, and there is a problem in that the regeneration efficiency is deteriorated because the heating air is directly discharged from the heater after receiving only the heat radiation.

 Also, most of the dehumidifiers have a structure in which the water tank in which the condensed water is stored by condensing by the condenser is manually drawn out, so that the structure of the dehumidifier is complicated and it is easy to slip off during use.

An object of the present invention is to provide a dehumidifier capable of improving the regeneration efficiency by making the regeneration path of the regeneration air as the shortest and bringing the regeneration air into direct contact with the heating line of the heater .

It is also an object of the present invention to provide a dehumidifier having a structure in which a water tank in which liquid condensed by a condenser is stored can be easily drawn out without dropping.

A heater for a dehumidifier according to the present invention includes a heater case having a heating device, a case having an opening, and a cover, and pores corresponding to the heating line of the heating device are provided on the bottom surface of the heater case. The pores ensure that all the regeneration air is directly heated by direct contact with the heating line so that the regeneration air comes into contact with the heating line immediately when the regeneration air passes through the pores.

In one refinement of the invention, the side adjacent to the back of the case of the opening and two sides adjacent to the side are closed by the heater case. In this case, all the regeneration air is forced to enter the heater case from the front side of the heater case through the pores, and is heated by the heating wire of the heating device.

In a further modified form of the present invention, a thermistor for sensing the temperature of the heater is further provided on the front surface of the case.

The dehumidifier of the present invention includes the front cover, the rear cover, and the dehumidifier main body between the front cover and the rear cover.

In a modified form of the dehumidifier of the present invention, the base is detachably connected to the combination of the water tank cover and the reservoir through the lower engagement member.

The method of controlling the moisture absorption rotor of the dehumidifier of the present invention rotates the moisture absorption rotor along the direction in which the heater is separated from the first condenser.

According to an embodiment of the present invention, a ventilation hole is formed on the bottom surface of the heater case in correspondence with the heating line of the heating device. When the regeneration air passes through the ventilation hole, the heating air comes into contact with the heating line, The moisture of the moisture absorption rotor is effectively removed from the air by improving the heating efficiency of the heater to improve the dehumidification performance of the entire dehumidifier.

Hereinafter, the present invention will be described in more detail by combining the drawings and specific embodiments. The following examples are merely illustrative of the present invention and are not intended to limit the scope of the present invention. Various modifications of the various equivalent forms of the invention by those skilled in the art are within the scope of the claims of this application.

1 is an exploded perspective view of a dehumidifier according to an embodiment of the present invention.

1, the dehumidifier is composed of a front cover 1, a rear cover 2, an upper cover 6 and a reservoir 5, as viewed from the outside.

The front cover 1 is provided with an air inlet 3 at one side along a long side and a detachable filter net 4 is installed at the air inlet 3. The filter net (4) collects foreign matter such as dust in the air sucked from the air inlet (3) and prevents the foreign matter from flowing into the dehumidifier.

The dehumidifier main body 8 is surrounded by the front cover 1, the rear cover 2, the upper cover 6 and the reservoir 5, It is installed directly below to accommodate condensate.

A blind 7 is provided between the upper cover 6 and the dehumidifier main body 8 and the blind 7 corresponds to the air outlet 9 provided in the upper cover 6, 7) can be used to change the direction of the dry air to be discharged.

2 is an exploded perspective view of a dehumidifier main body according to an embodiment of the present invention.

As shown in FIG. 2, the dehumidifier main body 8 includes a first condenser 10 and a heater 11 on a plane almost closest to the front cover 1. A moisture absorption rotor (12) is installed just behind the first condenser (10) and the heater (11).

The moisture absorption rotor (12) is installed in a cavity between the flat plate type front case (13) and the rear case (14). And a second condenser 15 is installed above the front case 13.

 The dehumidifying fan 17 is located in the cavity surrounded by the fan front cover 16 and the fan rear cover 18 and is rotated by the motor 19 provided in the fan rear cover 18. [ An air passage is formed in the lower portion of the dehumidifier main body 8 and a base 24 having a first interface 20 and a regeneration fan 23 is provided. A water tank cover (21) is provided between the base (24) and the reservoir (5).

The dehumidifier according to an embodiment of the present invention also has two air movement paths composed of a regeneration path and a dehumidifying path.

The dehumidifying path of the dehumidifier according to an embodiment of the present invention removes moisture in the outside air and at the same time the temperature of the outside air is relatively low. .

3, external air flows through the air intake port 3 located at one side of the front cover 1 through the filter net 4, under the action of the dehumidification fan 17 as a suction force, It is sucked into the dehumidifier.

First, the outside air passes from the front to the rear of the first condenser 10, where the outside air realizes heat exchange with the reconditioning air having a relatively high temperature due to the relatively low temperature characteristic, Lt; / RTI > Next, the outside air passes through the moisture absorption rotor 12, and the moisture absorption rotor 12 is composed of a plurality of hygroscopic elements in the rear case 14 and the rear case 14.

These hygroscopic elements include an adsorption-type inorganic hygroscopic agent such as silica gel, zeolite, molecular sieve or salts, or an ion-exchange resin hygroscopic agent, or a combination thereof. The moisture absorption rotor 12 is installed in the front case 13 and rotates at a uniform speed by the motor.

When the outside air passes through the moisture absorption rotor (12), it is dried by the moisture absorber in the hygroscopic element. The dried outside air is discharged from the dehumidifier through the air outlet 9 formed in the upper cover along the upper opening of the cavity in which the dehumidifying fan 17 is located by the dehumidification fan 17.

As shown in Fig. 3, the air for regeneration in the regeneration path circulates through the inside of the dehumidifier, thereby constantly drying the dehumidifying element that absorbs moisture, thereby restoring the dehumidifying ability of the dehumidifying element. The first condenser 10 is comprised of a plurality of vertically arranged condensing tubes and the lower end of the first condenser 10 is inserted into the first interface 20 of the base 24.

3, the regeneration air flows from the upper side downward into the condensation tube of the first condenser 10, and the outside air flows from the front to the rear of the first condenser 10 ) Of the condensation tube.

The temperature of the air for regeneration is lowered after heat exchange and is continuously condensed in the process of moving downward to form condensation on the inner wall of the condensing tube. These condensates fall downward by their own gravity, pass through the first interface 20, collect in the drain 36 of the base 24, and fall into the reservoir 5. [

The regeneration air passes through the first condenser 10 and enters the base 24 from the first interface 20 by the action of the regeneration fan 23 so that the air in the base 24 And then reaches the second interface 25.

The second interface (25) communicates with the bottom portion of the reconditioning air passage (22). The regeneration fan 23 is installed at the lower part of the regeneration air passage 22 and the air inlet surface of the regeneration fan 23 directly faces the second interface 25.

The regeneration air enters the regeneration air passage 22 located on the side of the dehumidifying fan 17 from below and is guided upward to the upper part. The regeneration air enters the second condenser 15 through the front opening of the upper portion of the regeneration air passage 22 and flows into the second condenser 15 through the regeneration air heated by the heater 11, Thereby realizing heat exchange. The second condenser (15) is composed of a plurality of transverse condensing tubes arranged in the transverse direction.

At this time, the air for regeneration passes through the second condenser 15 outside the condenser arranged in the transverse direction of the second condenser 15 from the rear to the front, To the heater 11 through the heater 11.

4, the heater 11 is composed of a fan-shaped outer case 26, a heater case 27, a heating device 28, and a cover 29. The cover 29 is fixed to the fan-shaped outer case 26 through a screw to form a cavity to receive the heating device 28 and the heater case 27. The heater case 27 has an opening in its rear surface, a cross-section of a pentagonal structure, and all five sides thereof are tightly surrounded by a mica plate. The heating device 28 has the same outline as the heater case 27 and is fixed in the heater case 27 as a set. The heater case 27 is open toward the rear surface of the cover 29 and corresponds to the opening 29a of the cover 29. [

Due to the good heat insulation performance of the mica, the amount of heat radiated by the heating device, for example, the heating wire 28, is basically limited within the heater case 27. The air for regeneration enters the case 26 of the heater 11 from the opening 30 on the upper side of the fan-shaped outer case 26.

5, one side of the heater case 27 closes the side adjacent to the opening 30 on the upper side of the fan-shaped outer case 26 and the two sides adjacent to the side, (30), that is, the side far from the moisture absorption rotor (12) is opened and used as an inlet for regeneration air.

According to such a configuration, the air for regeneration can only enter the heater 11 from the side near the front surface of the heater case 27. [ Therefore, all of the air for regeneration is forced to enter the heater case 27 through the vent hole 31 from the front of the heater case 27, and is heated by the thermal radiation generated by the heater 28.

Since the conventional heater has a gap between the heater case 27 and the front case 26, after the air for regeneration enters the front case 26 from the opening 30, The heater case 27 can not be heated sufficiently.

A thermistor 33 for sensing the temperature of the heater 11 is further provided on the front surface of the front case 26.

A ventilation hole 31 corresponding to the heating device, that is, the heating line 28 is provided substantially below the heater case 27 in a substantially parallel manner. The ventilation holes 31 are parallel to each other and the ventilation holes 31 are directly opposed to the heating line of the heating device 28.

The air for regeneration enters the heater case 27 through the vent hole 31 from the front of the heater case 27 and comes into direct contact with the heating device 28, Upon entering the case 27, the heating unit 28 is brought into contact with the heating wire of the heating unit 28 to raise the temperature.

Conventionally, pores are provided irregularly below the heater case, and the air for regeneration comes into contact with the heating wire after entering the heater case 27 through the irregularly installed pores. Since the distance between the air for regeneration and the heating line is relatively long, the heater is quickly removed after receiving a relatively low heat radiation.

However, according to the present embodiment, since the heater case 27 corresponding to the heating line of the heating device is provided, the regeneration air is brought close to the heating line, and the heating line is heated at relatively high temperature, Thereby improving the heating efficiency of the air.

3, the air for regeneration is heated by the heater 11 and then flows backward from the opening of the cover 29 and passes through the moisture absorption rotor 12 vertically. The moisture of the moisture absorption rotor (12) is evaporated by the high temperature thermal radiation of the heating line, and is removed by the high temperature regeneration air, thereby restoring the dehumidification ability.

After passing through the moisture absorption rotor (12), the high-temperature, humid air for regeneration enters the second condenser (15) through the swirling passage (32).

In the second condenser (15), the high temperature humid air for regeneration conducts heat exchange with the regeneration air coming out of the regeneration air passage (22).

6, when viewed from the front, the moisture absorption rotor 12 is arranged between the heater 11 and the first condenser 10 toward the first condenser 10 from the heater 11, It rotates counterclockwise. Therefore, the portion of the moisture absorption rotor 12 immediately heated by the heater 11 can reach the first condenser 10 after a relatively long distance.

The portion of the moisture absorption rotor 12 immediately heated by the heater 11 can be sufficiently cooled over a relatively long distance and the moisture is sufficiently evaporated. When the moisture absorption rotor 12 of this portion reaches the first condenser 10 side, evaporation and the remaining moisture are comparatively less and it is more advantageous to reduce the influence of moisture evaporated in the moisture absorption rotor 12 to the dehumidification effect.

On the contrary, if the moisture absorption rotor 12 rotates in the clockwise direction, the portion of the moisture absorption rotor 12 immediately heated by the heater enters the condensation region of the first condenser 10 in a high temperature state, There is a relatively large amount of water, which affects the dehumidifying effect of the dehumidifier.

As shown in FIG. 7, the condensed water generated in the regeneration path is collected in the base 24. The condensed water flows into the water inlet 35 of the water tank cover 21 through the drain port 36 at the center of the base 24 and is finally collected in the reservoir 5 below the water tank cover 21. [ The reservoir 5 is fixed to the lower side of the water tank cover 21 and is integrated with the water tank cover 21.

8, the water tank cover 21 has a handle 34, and the inlet 35 is located at a central position of the handle 34. As shown in FIG. The handle 34 is long and thin and has arc-shaped protrusions 38 at both ends thereof. The inlet (35) is somewhat higher than the handle (34).

A pair of engaging members 37 are provided on the surface of the base 24 of the dehumidifier. The engaging members 37 correspond to the projections 38 at both ends of the handle 34.

As shown in FIG. 9, the engaging member 37 has a screw hole 39 in the vertical direction for connecting with the base 24. A guide groove 40 is provided on one side of the two engaging members 37 facing each other so as to be matched with the projections 38. The guide groove 40 has not only a horizontal portion, And a vertical portion perpendicular to the horizontal portion is further provided. And a guide portion 41 is provided at the entrance side of the guide groove 40.

It should be noted that the directions of the guide portions 41 of the two engaging members 37 are opposite to each other. The water tank cover 21 is first rotated so that the projection 38 of the water tank cover 21 is guided by the guide 36. Then, (41) and slides on the horizontal portion of the guide groove (40), and continues to rotate until the vertical portion of the guide groove (40) becomes clogged. Conversely, the combination of the water tank cover 21 and the reservoir 5 can be separated.

Thus, the dehumidifier has two modes of drainage, manual and automatic. The water tank cover 21 and the reservoir 5 are engaged with the protrusion 38 via the engaging member 37 and fixed under the base 24 until the condensate is filled . The combination of the water tank cover 21 and the reservoir 5 is artificially separated and the reservoir 5 is manually lifted using the handle 34 of the water tank cover 21 I pour out the water.

When working in the automatic drain mode, the water tank cover 21 and the reservoir 5 are first removed, and the hose is connected to the drain port 36 to discharge the condensed water through the hose.
