Description

Clothing processing unit {LAUNDRY TREATMENT APPARATUS}

The present invention relates to a clothes treating apparatus having a function of drying clothes or bedding.

The apparatus for treating clothes refers to all devices that manage or process clothes, such as washing, drying, or removing wrinkles in clothes or bedding, such as at home or at a laundry. The clothes handling apparatus includes a washing machine, a dryer, a washing machine and a dryer.

A washing machine is a device for washing clothes or bedding, etc., and a dryer is a device for drying the clothes or bedding by removing moisture. The washing machine and dryer are devices that combine washing and drying functions.

Among them, in particular, the dryer supplies hot air to a treatment object such as clothes or bedding put into a drum (or tub) to evaporate moisture contained in the treatment object. The moisture of the object to be evaporated from the drum and the air exiting the drum contain the moisture of the object to be treated at a high temperature and high humidity. At this time, the type of dryer is classified into a condensation type and an exhaust type according to a method of treating the high temperature and high humidity air.

The condenser dryer condenses the moisture contained in the hot humid air through heat exchange while circulating without discharging the hot humid air to the outside. In contrast, the exhaust dryer directly discharges hot and humid air to the outside. The condensation dryers have a structure for treating condensed water, and the exhaust dryers have a structural difference from each other in that they have a structure for exhausting air.

The condensation dryer has a circulation passage for removing moisture from the air discharged from the drum and then heating it to enter the drum. Conventionally, since a circulation fan is disposed on a circulation passage perpendicular to the evaporator in front of the evaporator, a large flow path resistance is generated, and there is a problem that the heat exchange efficiency is low because the flow does not uniformly flow into the evaporator.

In order to solve this problem, it is necessary to simplify the circulation passage and to optimize the layout of various components on the base cabinet.

On the other hand, when the circulation fan is disposed behind the condenser, the condensed water on the bottom surface of the circulation passage may be scattered by the suction force of the circulation fan. In this case, the condenser may be cooled by the condensate to lower the efficiency of the condenser, or the condensate may be introduced into the circulation fan to adversely affect driving reliability. Therefore, while providing a space in which the evaporator and the condenser is spaced apart from the bottom surface, there is a need for a study of a new structure of the water cover that can limit the condensed water by the suction force of the circulation fan.

In addition, as described above, condensed water may be introduced into the circulation fan by suction force of the circulation fan. If the condensate is not drained, it adversely affects the driving reliability of the circulation fan. Therefore, the condensate introduced to the circulation fan must be provided to smoothly drain the condensate.

On the other hand, for assembly convenience, the circulation fan and the motor for driving the circulation fan are installed in the base cabinet as one assembly. As described above, when the circulation flow path is simply changed, the installation structure of the circulation fan-motor needs to be appropriately changed in response to the change.

In addition, according to the shape of the circulation fan, the noise, air volume, etc. generated during rotation is different. Therefore, it is necessary to study the optimum design conditions of the circulation fan to have a low noise, high airflow performance.

Meanwhile, after moisture is removed from the evaporator, the air heated in the condenser is introduced into the rear opening of the drum by blowing the circulation fan. A rear duct connector is provided to guide the air passing through the circulation fan to the rear opening of the drum. do.

The door 1020 may include a light transmitting unit. Therefore, even when the door 1020 is closed, the inside of the drum 1030 may be visually exposed through the light transmitting portion.

The drum 1030 is rotatably installed in the cabinet 1010. The drum 1030 is formed in a hollow cylindrical shape that is open to the front and rear, the front opening 1030 ′ of the drum 1030 is in communication with the clothes inlet 1011, the object to be processed in the drum 1030 It is configured to be accommodated.

A circulation passage 1200 is connected to the front opening 1030 ′ and the rear opening 1030 ″ of the drum 1030 so that air is formed in the drum 1030 and the closed loop 1200 by the circulation passage 1200. The humid air discharged through the front opening 1030 ′ of the drum 1030 is passed through the evaporator 1110 on the circulation passage 1200 to remove moisture and is heated through the condenser 1130. This high temperature dry air is introduced into the drum 1030 through the rear opening 1030 ″ of the drum 1030 to dry the object to be treated.

The outer circumferential surface of the roller 1060 in contact with the outer circumferential surface of the drum 1030 may be formed of an elastic material (for example, rubber).

Underneath the drum 1030 are heat pump cycle devices 1100. The lower side of the drum 1030 here means the space between the lower part of the drum 1030 and the base cabinet 1310. Heat pump cycle devices 1100 refer to devices that configure the cycle to sequentially evaporate-compress-condense-expand the refrigerant. When the heat pump cycle apparatuses 1100 are operated, the air is hot dried while sequentially exchanging heat with the evaporator 1110 and the condenser 1130.

An evaporator 1110 and a condenser 1130 are disposed on the circulation passage 1200 for heat exchange with air flowing along the circulation passage 1200. In the base cabinet 1310, a base flow path part 1310 ′ forming a part of the circulation flow path 1200 is formed.

The base flow path part 1310 ′ includes a heat exchange part 1312 in which an evaporator 1110 and a condenser 1130 are arranged for heat exchange. A guide part 1311 is provided at the front of the heat exchange part 1312 to guide the inflow of air into the heat exchange part 1312, and the air passing through the heat exchange part 1312 is blown in the rear of the heat exchange part 1312.

In addition, after the circulation fan is installed in the circulation fan accommodating part, the cover member 1330 is disposed to cover a portion opened to the rear of the circulation fan accommodating part. This completes the flow passage leading from the opening 1311 ′ of the guide portion 1311 to the exhaust port 1313 ″ of the circulation fan accommodating portion 1313. The flow passage forms an outlet duct 1210 and an inlet duct 1220. In connection, it may be referred to as a connection duct 1230 (see FIG. 2).

The front duct connector 1210 is configured to connect the front opening 1030 ′ of the drum 1030 and the guide portion 1311, and the rear duct connector 1220 is a rear opening 1030 ″ of the drum 1030. And the circulation fan accommodating portion 1313. The front duct connector 1210 may be referred to as an outlet duct in that it forms a flow path through which air inside the drum 1030 is discharged. 1220 may be referred to as an inlet duct in that it forms a flow path through which air is introduced into the drum 1030.

The air to be treated and dried in the drum 1030 is introduced into the heat exchange part 1312 through the guide part 1311 of the front duct connector 1220 and the base flow path part 1310 ′. Water is removed from the heat exchange unit 1312 and heated air is introduced into the drum 1030 through the rear duct connector 1220 by the circulation fan 1710.

Meanwhile, a flow path defined by the front duct connector 1210 and the guide part 1311 around the heat exchange part 1312 may be referred to as a first flow path, and the circulation fan accommodating part 1313 and the rear duct connector ( The flow path defined by 1220 may be referred to as a third flow path. Here, the flow path defined by the heat exchange unit 1312 may be referred to as a second flow path. That is, the air inside the drum 1030 is discharged through the first channel, the water is removed from the second channel and then reheated, and then flows back into the drum 1030 through the third channel.

The first flow path forms a path through which air discharged from the front opening 1030 ′ of the drum flows, and extends downward toward one side of the base cabinet 1310. The second flow path extends in a straight line toward the rear of one side of the base cabinet 1310. The third passage extends upward from one side of the base cabinet 1310 to connect the second passage and the vent 1050 ′ formed in the rear supporter 1050.

That is, the second passage and the third passage are disposed on one side of the base cabinet 1310. Therefore, a simpler circulation passage 1200 may be implemented than a conventional circulation passage in which the direction of the base cabinet 1310 is changed from one side to the other side.

The third passage includes a circulation fan 1710 which is disposed to face the second passage and sucks air that has passed through the second passage and blows the air to the vent of the rear supporter 1050.

The base cabinet 1310 is formed with a base flow path portion that forms part of the first flow path, the second flow path, and the third flow path. This will be described later.

When the air flowing along the circulation passage 1200 exchanges heat with the evaporator 1110, condensate is generated. More specifically, when the temperature of the air decreases due to heat exchange in the evaporator 1110, the amount of saturated water vapor that the air may contain decreases. Since the air recovered through the front duct connector 1210 contains moisture exceeding the amount of saturated water vapor, condensed water is inevitably generated.

The water pump 1440 (refer to FIG. 4) is provided in the clothes processing apparatus 1000. The water pump 1440 may be installed in the base cabinet 1310. The water pump 1440 moves the condensate to the bucket 1410, and the water bucket 1410 collects the condensate.

In FIG. 1, a circuit board is installed on a side wall of a cabinet 1010 corresponding to an upper right side of a drum 1030 opposite to the bucket 1410. Considering that the condensate is collected in the water tank 1410, the air containing moisture flows in the circulation passage 1200, and that electrical products such as circuit boards and devices are vulnerable to water, It is preferable to be spaced apart from the water tank 1410 or the circulation passage 1200 as far as possible.

FIG. 2 is a conceptual diagram illustrating the circulation of air through the drum 1030 and the circulation passage 1200 shown in FIG. 1. In FIG. 2, the left side corresponds to the front F of the drum 1030, and the right side corresponds to the rear R of the drum 1030.

In order to dry the processing object put into the drum 1030, the high temperature dry air is supplied to the inside of the drum 1030, the air to dry the clothes is recovered again to remove moisture and heated, the drum 1030 The process of resupply should be repeated. In order to repeat this process in a condensation dryer, air must be continuously circulated through the drum 1030. The air is circulated through the drum 1030 and the circulation passage 1200.

The inlet duct 1220 extends upwardly from the connecting duct 1230 to cover the rear surface of the rear supporter 1050 and communicates with the vent 1050 ′ formed in the rear supporter 1050. The rear surface of the rear supporter 1050 refers to the surface facing the rear of the clothes processing apparatus 1000. Hot dry air is supplied into the drum 1030 through the vent 1050 '.

Since the drum 1030 and the connecting duct 1230 are arranged to be spaced apart from each other along the vertical direction, the inlet duct 1220 is toward the rear of the drum 1030 from the connecting duct 1230 disposed below the drum 1030. Extend upwards. The inlet duct 1220 may also extend in the vertical direction like the outlet duct 1210, but the length of the vertical extension of the inlet duct 1220 in the connection structure is longer than that of the outlet duct 1210.

The front duct connector 1210 is equipped with a communication hole 1040". The opening 1311 'formed in the base cabinet 1310, the opening defined by the base flow path part 1310', and the front cover 1321 are connected.

The front duct connector 1210 extends downwardly from the communication hole 1040 ". In this figure, the front duct connector 1210 is shown including the filter guide 1211 and the duct connector 1212. This figure is shown. Alternatively, the front duct connector 1210 may be formed of a single member.

The filter guide 1211 is mounted on the front supporter 1040 and inserted into the communication hole 1040 ". The filter guide 1211 may be mounted on the circumference of the front supporter 1040. The filter guide 1211 The filter unit 1240 is detachably coupled therein and configured to filter lint in the air discharged through the front opening 1030 ′ of the drum 1030.

The filter unit 1240 may include a plurality of filters. In this figure, the inner filter 1242 is inserted into the outer filter 1241, and the outer filter 1241 is inserted into the filter guide 1211 to be arranged to penetrate the communication hole 1040 ″. The number of holes of the mesh net per unit area of the outer filter 1241 and the inner filter 1242 may be configured differently.

One side of the duct connector 1212 may extend downwardly inclined toward the opening 1311 ′ formed at one side of the base cabinet 1310.

4 is a perspective view illustrating main components mounted on the base cabinet 1310 and the base cabinet 1310 illustrated in FIG. 1, and FIG. 5 illustrates the main components illustrated in FIG. 4 separated from the base cabinet 1310. 6 is a plan view of the base cabinet 1310 illustrated in FIG. 5.

4 to 6, a base cabinet 1310 is disposed below the drum 1030 to provide a space in which various components are mounted, including the heat pump cycle devices 1100. The bottom surface of the base cabinet 1310 may form the bottom surface of the clothing processing apparatus 1000.

The base cabinet 1310 includes a drum motor mounting unit 1314, a compressor mounting unit 1315, a base flow path unit 1310 ′, and a condensate recovery unit 1316. The drum motor mounting unit 1314 and the compressor mounting unit 1315 are disposed on one side of the base flow path unit 1310 ′. In this embodiment, it is shown that the drum motor mounting portion 1314 and the compressor mounting portion 1315 are disposed at the left front and the rear of the base flow path portion 1310 ', respectively.

The drum motor mounting unit 1314 is equipped with a drum motor 1800 for generating a driving force for rotating the drum 1030. A drum (not shown) for transmitting the driving force of the drum motor 1800 to the drum 1030 may be connected to the drum motor 1800. The belt is disposed to surround the outer circumference of the drum 1030.

Pulleys 1810 and springs (not shown) may be used to adjust the tension on the belt.

Pulley 1810 may be configured to apply a certain tension to the belt. The pulley 1810 is rotatably configured to a bracket (not shown) mounted to the drum motor mounting unit 1314 or the drum motor mounting unit 1314.

In order to adjust the tension of the belt, the drum motor 1800 may be rotated within a predetermined angle range around one axis, and then may be configured to be retractable to an initial position by an elastic force of a spring. To this end, the drum motor 1800 is configured to be rotatable about one axis of the drum motor mounting unit 1314, and the spring may be connected to the drum motor mounting unit 1314 and the drum motor 1800, respectively.

A blowing fan 1820 may be mounted on the shaft of the drum motor 1800. In this embodiment, the belt is connected to the shaft provided on one side of the drum motor 1800, it is shown that the blower fan 1820 is mounted on the shaft provided on the other side of the drum motor 1800. Shafts provided on both sides of the drum motor 1800 rotate in the same direction and at the same speed.

When two shafts are provided in one driving motor 1730, the driving force 1730 has many advantages in terms of improving power consumption of the clothes treating apparatus 1000. Basically, compared to the case where the driving motor 1730 for rotating the drum 1030 and the driving motor 1730 for rotating the blower fan 1820 are respectively provided, power consumption is reduced by half.

In particular, the time point at which rotation of the blower fan 1820 is required is the same as the time point at which the drum 1030 rotates. This is because hot dry air is supplied to the drum 1030 while the drum 1030 is rotating, and hot and humid air may leak from the drum 1030. Therefore, a state in which rotation of one of the drum 1030 and the blower fan 1820 is unnecessary does not occur.

In the present embodiment, it is shown that the blowing fan 1820 is configured as an axial fan, and is configured to blow air toward the front of the cabinet 1010. However, the present invention is not necessarily limited thereto. For example, the blowing fan 1820 may be configured as a sirocco fan.

The blowing fan 1820 is rotated according to the driving of the drum motor 1800 to blow air in the internal space between the cabinet 1010 and the drum 1030. Therefore, air leaking finely into the gap between the drum 1030 and the front supporter 1040 and the gap between the drum 1030 and the rear supporter 1050 causes the internal fan to flow through the internal space. do. Therefore, the occurrence of condensation caused by the stagnation of air can be reduced.

Meanwhile, the heat dissipation fan may be mounted on the circuit board constituting the controller. The heat dissipation fan dissipates the elements mounted on the circuit board, and forms a circulating flow that circulates air in the internal space between the cabinet 1010 and the drum 1030 together with the blower fan 1820. The heat dissipation fan may be positioned above the base flow path part 1310 ′ and may be configured to blow air downward, that is, toward the base flow path part 1310 ′.

The heat dissipation fan may be disposed on an opposite side of the blower fan 1820 based on the center of the drum 1030 to form a circulating flow surrounding the drum 1030 together with the blower fan 1820. For example, a blowing fan 1820 may be disposed at a lower left side of the drum 1030, and a heat radiating fan may be disposed at an upper right side of the drum 1030.

In the cabinet 1010, an exhaust fan 1730 is installed to discharge air in the space between the cabinet 1010 and the drum 1030 to the outside. That is, the air leaked from the drum 1030 is exhausted to the outside while continuously flowing by the blowing fan 1820 and the heat radiation fan (not shown). The exhaust fan 1730 may be located behind the heat radiating fan. In the present embodiment, it is shown that the exhaust fan 1730 is provided on the rear wall of the cabinet 1010 located behind the heat radiating fan.

The compressor mounting unit 1315 is equipped with a compressor 1120 for generating compressed air for heat exchange. The compressor 1120 is an element constituting the heat pump cycle devices 1100, but does not need to be installed in the base flow path part 1310 ′ because it does not directly exchange heat with air. Rather, since the compressor 1120 may interfere with the flow of air if the compressor 1120 is installed in the base flow path part 1310 ', the compressor 1120 is preferably installed outside the base flow path part 1310'.

The refrigerant is evaporated (liquid-> gas) while absorbing heat from the evaporator 1110, and the refrigerant is brought into the compressor 1120 at a low temperature and low pressure gas state. The gas-liquid separator 1140 is installed upstream of the compressor 1120 based on the flow of the refrigerant. The gas-liquid separator 1140 separates the refrigerant flowing into the compressor 1120 into the gaseous phase and the liquid phase, so that only the refrigerant in the gas phase flows into the compressor 1120. According to this, the problem that the liquid refrigerant flows into the compressor 1120 and causes a failure or a decrease in efficiency can be prevented.

The compressor mounting unit 1315 is provided with at least three fixed ribs 1315 'for fixing the compressor 1120. In order to reduce vibration, the fixed rib 1315 ′ may extend through the compressor mounting portion 1315 to the rear surface. The fixed rib 1315 'extending to the rear surface is configured not to touch the bottom surface.

The compressor mounting unit 1315 may be provided with support ribs 1315 ″ for supporting the compressor 1120. The support ribs 1315 ″ are centers of virtual polygons formed by connecting a plurality of fixed ribs 1315 '. It may consist of a combination of portions extending radially from and portions concentric to said center.

A compressor cooling fan 1720 may be installed adjacent to the compressor 1120. The compressor cooling fan 1720 is configured to blow air or blow air toward the compressor 1120. The temperature of the compressor 1120 may be lowered by the compressor cooling fan 1720, and as a result, the compression efficiency may be improved. In this embodiment, it is shown that the compressor cooling fan 1720 is installed on the rear wall of the cabinet 1010 located behind the compressor 1120.

The base flow path part 1310 ′ forms part of the circulation flow path 1200. Based on the air flow, the base flow path part 1310 ′ is divided into a guide part 1311, a heat exchange part 1312, and a circulation fan accommodating part 1313. An evaporator 1110 and a condenser 1130 are disposed in the heat exchange part 1312, and a circulation fan 1710 is disposed in the circulation fan accommodating part 1313 to face the condenser 1130.

The guide part 1311 corresponds to a portion into which air discharged from the front opening 1030 ′ of the drum 1030 flows. An opening opened upward is formed in the guide part 1311, and the opening communicates with the front duct connector 1210. The air flowing downward through the front duct connector 1210 is redirected from the guide portion 1311 to the rear of the base cabinet 1310 and flows into the heat exchange portion 1312.

The heat exchange unit 1312 corresponds to a portion where an evaporator 1110 for removing moisture of air introduced from the guide unit 1311 and a condenser 1130 for heating the air from which the moisture is removed are installed. The heat exchange part 1312 may extend in a straight line from the front of the base cabinet 1310 toward the rear.

The refrigerant compressed by the compressor 1120 becomes a high temperature and high pressure and flows to the condenser 1130. In the condenser 1130, the refrigerant liquefies while releasing heat. The liquefied high pressure refrigerant is depressurized in an expander (not shown). The low temperature low pressure liquid refrigerant enters the evaporator 1110.

The circulation fan accommodating part 1313 corresponds to a portion in which the circulation fan 1710 for sucking and blowing air passing through the heat exchange part 1312 is accommodated. The circulation fan 1710 is disposed so that the rotating shaft faces the condenser 1130 and the evaporator 1110, and is composed of a sirocco fan that blows the air in front of the air, that is, the condenser 1130, to the side.

The hot dry air passing through the condenser 1130 is supplied to the drum 1030 through the rear duct connector 1220 via the blower fan 1820 receiving portion. The hot dry air supplied to the drum 1030 evaporates the moisture of the object to be treated and becomes hot and humid air. The high temperature and high humidity air is recovered through the front duct connector 1210, and heat exchanges with the refrigerant in the evaporator 1110 to become low temperature air. At this time, as the temperature of the air is lowered, the amount of saturated water vapor of the air is reduced, and the moisture contained in the air is condensed. Subsequently, the low temperature dry air is heat-exchanged with the refrigerant in the condenser 1130 to become the high temperature dry air and is supplied to the drum 1030 again.

The evaporator 1110, the condenser 1130, and the circulation fan 1710 mounted on the base flow path part 1310 ′ are eccentrically positioned to one side from the center of the base cabinet 1310.

The bottom surface of the heat exchange part 1312 is formed to be inclined downward toward the rear. In addition, the bottom surface of the base passage 1310 ′ in which the condenser 1130 is disposed is inclined downward toward one side of the condenser 1130 in which the communication hole 1316 ′ is formed. Due to this inclined structure, the condensed water dropped to the bottom surface of the heat exchange part 1312 in which the evaporator 1110 is disposed flows toward the bottom surface of the heat exchange part 1312 in which the condenser 1130 is disposed, and then communicates with the communication hole 1316 ′. It may be introduced into the condensate recovery unit 1316 through.

Below the evaporator 1110 is a U trap. The U trap includes a trap groove 1312 'formed on the bottom surface of the heat exchanger 1312 on which the evaporator 1110 is disposed, and a trap film 1930 extending downward from the water cover 1900 and inserted into the trap groove 1312'.

However, the end of the trap film 1930 is configured not to touch the bottom surface of the trap groove 1312 '. As a result, a U-shaped space is formed in the trap groove 1312 'by the end of the trap film 1930.

The condensate generated in the evaporator 1110 falls to the bottom surface and flows backward by the above-described inclined structure. Here, some of the moving condensate is introduced into the trap groove 1312 'to fill the trap groove 1312' with condensate.

An end portion of the trap film 1930 extending into the trap groove 1312 ′ is immersed in the condensed water collected in the trap groove 1312 ′. Therefore, the space between the lower part of the evaporator 1110 and the bottom surface of the base flow path part 1310 'is completely blocked by the condensed water trapped by the trap film 1930 and the trap groove 1312'.

The leakage of air to the bottom of the evaporator 1110 by this U trap can be prevented. That is, the U trap seals a flow path formed under the evaporator 1110 so that most of the air flowing through the guide part 1311 and into the heat exchange part 1312 may participate in heat exchange with the evaporator 1110. Therefore, the condensation efficiency of the air passing through the evaporator 1110 may be improved.
