Description

Dehumidifier {dehumidifier}

The present invention relates to the improvement of the material and structure of the drain pan, which serves to guide the water dripping from the heat exchanger to the bucket.

Generally, dehumidifier is a generalized device that removes moisture contained in indoor air by using a refrigeration cycle that compresses, condenses, expands and evaporates refrigerant.

These dehumidifiers are dehumidified by absorbing moisture in the indoor air by the rapid temperature drop caused by inhaling the humid air in the room and passing the evaporative heat exchanger at low temperature, and the dehumidified dry air is in a high temperature state. It is equipped with a circulation system which repeats the process of converting to room temperature and returning to the room while passing through a phosphorus condensation heat exchanger.

The refrigeration cycle of the dehumidifier consists of a compressor that compresses the refrigerant gas to a high temperature in order to continuously perform the compression, condensation, expansion, and evaporation of the refrigerant, a condensation heat exchanger that liquefies the refrigerant in a gaseous state, and a refrigerant in a liquid state. It consists of a capillary tube to reduce the pressure, and an evaporative heat exchanger having an endothermic action while passing a low-temperature / low-pressure gas refrigerant.

For reference, the biggest difference between the refrigeration cycle of the dehumidifier and the refrigeration cycle of the air conditioner and the refrigerator is that in the former case, the evaporative heat exchanger and the condensation heat exchanger are installed in close proximity to each other, so that the difference in distance between the two heat exchangers is achieved. There is a structural difference between the two heat exchangers to prevent heat exchange between the two heat exchangers.

1 is an exploded perspective view illustrating an example of a conventional dehumidifier, and FIG. 2 is a combined state diagram of FIG. 1.

As shown in the drawing, a conventional dehumidifier includes a cabinet 10, a grill type front panel 11 installed at an air discharge side of the cabinet 10, the cabinet 10, and a compressor 1. The exterior is comprised by the base plate 12 which is seated.

An air filter 13 is installed inside the cabinet 10 to purify the inlet air toward the air inlet side, and the condensation heat exchanger 14a and the incremental heat exchanger 14b are provided inside the air filter 13. It consists of a heat exchanger unit 14 is dehumidifying action is installed, the front panel 11 side of the heat exchanger unit 14 by sucking the indoor air into the cabin by the rotational force to reduce the air in the cabin to the room The blowing fan 15 is installed.

At this time, the blowing fan 15 is located on the air passage hole 16a formed in the center of the flat shroud (shroud) (16), by the fan mounter 17 is fastened to the shroud (16) Supported.

In addition, a bottom portion of the heat exchanger unit 14 is provided with a barrier “18” having a substantially “c” shape. The barrier 18 collects water falling from the heat exchanger unit 14. Bucket 19 is installed.

At this time, the barrier 18 is provided with a water quantity detection switch (not shown) for detecting a certain amount of water in the bucket 19 to cut off the power supply.

In addition, a drain pan 20 is installed between the heat exchanger unit 14 and the bucket 19 to guide the dehumidifying water flowing from the heat exchanger unit 14 to the bucket 19.

At this time, the upper surface of the drain pan 20 forms an inclined surface 20a to guide the dehumidifying water falling from the heat exchanger unit 14, and discharges the guided dehumidifying water toward the bucket 19 on the inclined surface 20a. The drainage hole 20b is formed.

In addition, an outer protrusion 20e is formed on an outer surface of the extension part 20c formed at both sides of the drain pan 20, and is coupled to the coupling hole 18a formed at both sides of the barrier 18. In addition, an inner protrusion 20d is formed on an inner side surface of the extension part 20c to be coupled to the inclined groove 19a formed on both sides of the upper part of the bucket 19.

The conventional dehumidifier configured as described above operates with the compressor 1 and the blower fan 15 being supplied with power.

Accordingly, while indoor air is introduced into the aircraft by the rotational force of the blower fan 15, the air is rapidly lowered while being passed through the evaporation heat exchanger 14b of the heat exchanger unit 14 positioned on the flow path of the air, and thus contained in the air. Moisture builds up on the evaporative heat exchanger (14b), and as this action is repeated, water droplets are formed and fall into the drain pan (20).

The dehumidifying water dropped into the drain pan 20 is led to the drain hole 20b by the inclined surface 20a formed at an upper portion thereof, and is finally collected into the bucket 19 located at the bottom of the drain pan 20.

At this time, the condensation heat exchanger (14a) serves to prevent moisture from freezing on the evaporation heat exchanger (14b), and serves to convert the lowered air to room temperature through the evaporation heat exchanger (14b). .

On the other hand, the dry air in which the moisture is removed by the above-described process is reduced to the room through the front panel 11 by the rotational force of the blower fan (15).

However, the conventional drain pan 20 as described above has the following problems.

First, since the material of the drain pan 20 is made of synthetic resin (HIPS) having poor thermal insulation, water droplets may form on the bottom surface of the drain pan 20 due to the temperature difference between the cabin and the outside of the cabin.

This causes a subsequent problem in which water droplets formed on the bottom surface of the drain pan 20 leak to the outside of the dehumidifier. This is one of the main problems to be solved in the present invention.

Second, since the drain pan 20 is fastened by a screw to the top of the barrier 18, there is a problem that the coupling labor is increased, which leads to a decrease in productivity.

Third, although the drain pan 20 is made of synthetic resin that is lighter than metal, the weight loss effect is not so great.

Fourth, since the drain pan 20 is made of synthetic resin, it is possible to obtain an effect of reducing driving noise to some extent as compared with the case of metal, but the effect is insignificant. In other words, considering that the dehumidifier has a noise source such as a compressor and a fan motor, low noise remains a problem to be solved.

The present invention has been made to solve the above-mentioned conventional problems, and aims to prevent dew from forming on the drain pan, which is a boundary thereof, due to a temperature difference between the inside and the outside of the dehumidifier.

According to the first aspect of the present invention for achieving the above object,

A heat exchanger unit comprising an evaporative heat exchanger and a condensation heat exchanger; A barrier positioned at a lower portion of the heat exchanger unit, the barrier having an open shape at least rearward and upwardly and having a portion of the bucket inserted through the open rearward; The dehumidifier is coupled to the upper portion of the barrier by an insertion, and one side includes a drain pan of a heat insulating material having a drainage hole to drain water drained from the heat exchanger unit to a bucket.

Moreover, according to the 2nd aspect of this invention,

A heat exchanger unit comprising an evaporative heat exchanger and a condensation heat exchanger; A barrier positioned at a lower portion of the heat exchanger unit, the barrier having an open shape at least rearward and upwardly and having a portion of the bucket inserted through the open rearward; A drain pan coupled to an upper portion of the barrier and having a drain hole at one side to drain water from the heat exchanger unit into a bucket; A dehumidifier is provided, which is installed on the top or bottom surface of the drain pan and comprises an insulation plate having another drainage hole coincident with the drainage hole of the drain pan.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a first embodiment of the dehumidifier according to the present invention.

The dehumidifier of the first embodiment is coupled to the upper portion of the barrier 30 by a press-fit method, and on one side thereof, a drain hole 41 and a downward direction toward the drain hole to drain the water dripping from the heat exchanger unit 14 into the bucket. It comprises a drain pan 40 having a photographic slope 42 together, the drain pan 40 is characterized in that the insulating material.

In this case, the method of coupling the drain pan 40 by press-fitting the upper portion of the barrier 30 may be applied in various forms.

For example, a guide groove is formed at an upper end of the barrier 30 to push the drain pan 40 along the guide groove from the rear of the barrier 30, and as shown in FIG. 3, an upper end of the barrier 30. The step 31 may be formed in the drain pan 40 by inserting the upper part of the barrier 30 into the step 31 and the like.

This method can be combined simply by fitting without a separate fastening means can achieve a reduction in the coupling process and structural simplification.

In addition, although various products having heat resistance and thermal shock resistance are released as the heat insulating material, it is preferable to be a foamed resin such as styrofoam from the viewpoint of economy and light weight.

In addition, the reason why the drain pan 40 is made of a heat insulating material is that the drain pan 40 is installed at the boundary between the inside and the outside of the dehumidifier, so that if the internal temperature and the external temperature difference of the dehumidifier are large, dew may form on the drain pan 40. This is to prevent it.

4 is a second embodiment of the dehumidifier according to the present invention.

The dehumidifier of the second embodiment combines a case 50 having a certain strength to the surface of the drain pan 40 as a way to solve the problem, since the problem may occur in strength when the drain pan 40 is formed of styrofoam only. .

In this case, it is preferable that the case 50 is made of synthetic resin having a low price, light weight, and relatively low thermal conductivity.

In addition, it is necessary to have a drainage hole 51 at a position corresponding to the drainage hole 41 formed in the drain pan 40, which is an essential condition for achieving drainage.

On the other hand, in the first and second embodiments, since the drain pan 40 is made of foamed resin having a weakness in strength, it is impossible to couple the water tank 19 with the drain pan 40 as in the prior art. Therefore, structural improvement that requires the projection 32 to be coupled to the inclined grooves 19a of the bucket 19 on both sides of the inner surface of the barrier 30 in place of the drain pan 40 should be performed in parallel (see FIG. 3). .

5 is a third embodiment of a dehumidifier according to the present invention.

In the dehumidifier of the third embodiment, the drain pan 40 maintains the existing shape, but combines the insulation plate 60 on the top or bottom of the drain pan 40 separately.

Unlike the first and second embodiments, this embodiment is more practical because the drain pan 40 only needs to combine the heat insulating plate 60 while maintaining the existing structure without forming a protrusion separately on the barrier 30.

However, the drain pan 40 should have a coupling portion to allow the heat insulating plate 60 to be coupled. For example, in FIG. 5, a supporting piece 43 is formed on the inner surface of the extension part 40a of the drain pan 40 to form a heat insulating plate. 60 can be inserted between the upper end of the drain pan 40 and the support piece 43.

At this time, in the heat insulating plate 60, drainage is made only when another drainage hole 61 is formed at the same position as the drainage hole 41 formed in the drain pan 40.

6 is a fourth embodiment of the dehumidifier according to the present invention.

In the dehumidifier of the fourth embodiment, a coupling hole 33 is formed in an upper portion of the front surface of the barrier 30, and the coupling hole 33 is provided with a coupling support 70 having a “C” shape. The drain pan 40 is mounted on the support 70.

And, both ends of the drain pan 40 to form a coupling protrusion 44 to obtain a coupling force with the barrier 30, so as to be coupled to another coupling hole 34 previously formed on both sides of the barrier 30. One configuration.

The present invention as described above has the following effects.

First, it is possible to prevent water droplets from forming in the drain pan by blocking heat exchange between the cabin and the outside by using the drain pan itself as a heat insulating material or by separately adding a heat insulating plate to the drain pan.

Second, as the drain pan and the barrier are combined by a fitting method rather than a fastening method, there is an advantage of simplifying the coupling process and reducing components.

Third, since the drain pan is made of foamed resin, the weight loss effect is large.

Fourth, since the drain pan is made of foamed resin, vibration and noise are less than that made of metal or synthetic resin having strength.
