Description

Dual type dryer {DUAL TYPE DRYER}

The present invention relates to a dryer, and more particularly, to a dual type dryer including a main dryer having a relatively large capacity and an auxiliary dryer having a relatively small capacity.

The dryer is a device for drying clothes and is a device for removing moisture from clothes by supplying dry hot air to clothes.

Generally, a dryer generally uses an electric heater, a gas heater, and a heat pump as a heat source for heating the air. Thus, the dryer can be divided according to the type of heat source.

Also, the dryer can be divided by the air flow system. The exhaust-type dryer is a dryer for discharging hot and humid air after moisture is removed from the clothes, and the circulating dryer is a dryer that recycles hot and humid air through circulation without discharging it to the outside. The circulating type dryer is used after condensing moisture in hot and humid air and then heating it again. Such a circulation type dryer can be referred to as a condensation type dryer.

According to the condensing system, the condensing dryer can be divided into a water-cooled dryer, an air-cooled dryer, and a heat pump dryer.

Of course, in recent years, a lot of techniques have been disclosed for a dryer in which an exhaust-type dryer and a circulating-type dryer are implemented in a complex manner, so it may not be easy to distinguish between an exhaust-type dryer and a circulation type dryer.

In addition, the dryer can be variously divided according to the shape of the laundry receiving portion accommodating the clothes to be dried. The horizontal drum drum dryer can be referred to as a drum type drum in which the laundry accommodating portion rotates with respect to the horizontal axis, and the vertical drum drum dryer can be referred to as a drum drum type drum rotating around the vertical axis. Further, a dryer having a laundry accommodating portion fixed in the cabinet may be referred to as a cabinet dryer or a refresher.

Generally, a large number of circulating drum dryers are used at home. Conventionally, a heater dryer using an electric heater as a heating source of air has been widely used. However, in recent years, the spread of a heat pump dryer using a refrigeration cycle is increasing.

Hereinafter, a general heater dryer and a heat pump dryer will be described.

1 is a conceptual view briefly showing an example of a heater dryer.

As shown in Fig. 1, the heater dryer includes a drum 10 and an air circulating part 20 for circulating air through the drum. Air discharged from the drum through the air circulation unit 20 flows into the drum again. Thus, the air circulates through the air circulation unit 20. [ A drying fan (50) is provided for circulating the air. The drying fan (50) is provided in the air circulation unit (20) to generate a flow of air.

The air circulation unit 20 may include a separate duct, and a part of the flow channel may be formed at the base of the dryer. In addition, the drum 10 may also be a part of the air circulation part.

In order to dry the laundry in the drum 10, the air is heated through the heater 60, that is, the electric heater. The heated air flows into the drum 10 to remove moisture from the laundry.

And the air that has become hot and humid is discharged from the drum and flows into the condenser 40. Of course, a filter 30 may be provided between the drum 10 and the condenser 40 to remove foreign substances such as lint in the air. Such a filter can be called a lint filter.

The high temperature and high humidity air condenses moisture in the condenser (40) to dry air. In the condenser 40, hot and humid air is heat-exchanged with low-temperature outside air. At this time, moisture in hot and humid air is condensed and removed.

 The condenser 40 may be equipped with a cooling fan 45 for the inflow and outflow of outside low-temperature air. The cooling fan (45) is provided in the cooling flow path (46).

The cooling channel may be configured to supply outside air to the condenser 40 and then discharge the outside air to the outside of the dryer. As a result, in the heater dryer, the condenser 40 may be configured to cross the air circulation unit 20 and the cooling flow path 46.

The low temperature dry air discharged from the condenser (40) is heated through the heater (60) and converted into hot dry air. The high-temperature dry air flows into the drum 10 again.

Therefore, the air circulates through the drum 10, the condenser 40, the drying fan 50, and the heater 60, and drying is performed through heating and condensation of the circulating air.

The dryer shown in FIG. 1 is a blower type dryer because it blows air from the rear of the drum 10 to the drum 10, and on the basis of the illustrated drum 10, And the left side corresponds to the rear side of the dryer. Therefore, air for drying is substantially introduced into the rear of the drum 10, and then discharged to the front of the drum 10. [

FIG. 2 is a plan view schematically showing the arrangement relationship of the main components of the dryer shown in FIG. 1 based on the dryer base 70.

The drum 10 and the heater 60, which are not directly mounted on the base 70, are omitted. It can be said that the upper part of the dryer 70 and the lower part of the dryer 70 correspond to the front of the dryer 70 as shown in FIG.

A condenser 40 is provided on the left side of the dryer base 70 and a cooling fan 45, a motor 55 and a drying fan 50 are provided on the right side. The motor 55 may be provided to drive the drying fan 50.

1, the drying fan 50 may be provided between the filter 30 and the condenser 40, as shown in FIG. 1, in which the drying fan 50 is installed in front of the dryer 10 and below the drum 10. In this case, . ≪ / RTI >

In the example shown in FIG. 2, the drying fan 50 sucks air in the drum 10 in front of the drum 10, so that it can be called a suction type dryer.

That is, the drying fan 50 can be divided into a suction type dryer and a blower type dryer depending on the position of the drum 10 in front of or behind the drum 10 in relation to the drum 10 or the heater.

The flow of air will be described with reference to FIGS. 1 and 2. FIG.

The air introduced into the drum 10 is discharged through the front of the drum 10, descends and flows into the condenser 40. The air discharged from the condenser (40) rises and flows back into the drum (10) through the rear of the drum. These ducts may be connected to the drum 10 or the base 70 to form an overall air circulation unit 20. The air circulation unit 20 may include a plurality of ducts.

The outside air is introduced into the dryer through the cooling flow path 46 from the rear of the dryer and supplied to the condenser 40.

The external air supplied to the condenser 40 is heat-exchanged with the circulating air in the condenser 40, and then discharged to the side of the dryer. That is, as the cooling fan 45 is driven, outside air is introduced through the cooling channel 46 and then discharged. Of course, in order to increase the heat exchange efficiency, the flow direction of the circulating air in the condenser 40 and the flow direction of the external air may be vertical.

3 is a conceptual view briefly showing an example of a heat pump dryer.

As shown in FIG. 3, the heat pump dryer includes a drum 10 and an air circulation unit 20 for circulating air through the drum 10. The air discharged from the drum 10 through the air circulation unit 20 is condensed and heated and flows into the drum 10 again. Thus, the air circulates through the air circulation unit 20. [

A drying fan (50) is provided for circulating the air. The drying fan (50) is provided in the air circulation unit (20) to generate a flow of air.

In order to dry the clothes in the drum 10, air is heated and cooled through the heat pump system 80. The heat pump system 80 is one refrigeration cycle using refrigerant. Thus, the heat pump system 80 includes a refrigerant line 82, an evaporative heat exchanger 81, a compressor 83, a condenser heat exchanger 84 and an expansion means 85.

Specifically, the refrigerant flows through the refrigerant pipe 82 in the order of the evaporative heat exchanger 81, the compressor 83, the condenser heat exchanger 84, and the expansion means 85 in this order.

In the evaporating heat exchanger (81), the refrigerant absorbs heat and evaporates. Accordingly, the evaporating heat exchanger 81 cools the circulating air through the heat exchange between the refrigerant and the circulating air to condense the moisture. Therefore, from the viewpoint of circulating air, the evaporation heat exchanger 81 can be regarded as a condenser corresponding to the condenser 40 of the heater dryer.

In the condensing heat exchanger (84), the refrigerant radiates heat and condenses. Accordingly, the condensing heat exchanger 84 heats the circulating air through heat exchange between the refrigerant and the circulating air. Therefore, from the viewpoint of the circulating air, the condensing heat exchanger 84 can be referred to as a heater corresponding to the heater 60 of the heater drier.

Accordingly, the condensation process and the heating process of the circulating air are performed while passing through the heat pump system 80, and the circulated air flows into the drum 10 again. Of course, a filter 30 may be provided between the drum 10 and the evaporative heat exchanger 81 to remove foreign matter such as lint in the air.

On the other hand, on the drum 10 shown in FIG. 3, the right side corresponds to the front side of the dryer and the left side corresponds to the rear side of the dryer. Similarly, the dryer shown in FIG. 3 is a blow type dryer because the drying fan 50 is positioned behind the drum 10 and blows air into the drum 10. However, the dryer shown in Fig. 4 can be referred to as a suction type dryer as described above.

FIG. 4 is a plan view schematically showing the arrangement relationship of the main components of the dryer shown in FIG. 3 with reference to the dryer base 70. The drum 10 which is not directly mounted on the base 70 is omitted. It can be said that the upper part corresponds to the front side of the dryer and the lower part corresponds to the front side of the dryer with reference to the base 70 shown in Fig.

The evaporator 81 and the condensing heat exchanger 84 are provided on the left side of the dryer base 70 and the expansion device 85, the compressor 83, the motor 55 and the drying fan 50 are provided on the right side. Respectively. The motor 55 may be provided to drive the drying fan 50.

The flow of air will be described with reference to FIGS. 3 and 4. FIG.

The air inside the drum is discharged from the drum through the front of the drum by the suction force of the drying fan (50). The outflowed air descends and the moisture is removed and heated through the evaporating heat exchanger 81 and the condensing heat exchanger 84. Thereafter, the air ascends and flows into the drum through the rear of the drum 10. [

Since the cooling and heating of circulating air is performed through the heat pump system 80, the heat pump dryer does not need to have the cooling fan 45 or the cooling channel 46 as in the heater drier.

Such a heat pump dryer can be said to have the same filtering, condensation, and heating processes as the above-described heater dryer and circulating air. However, it can be said that the method of heating and condensation is different. The heater 60 of the heater drier and the condenser 40 correspond to the condensing heat exchanger 84 and the evaporation heat exchanger 81 of the heat pump dryer, respectively. The heater (60) and the condensing heat exchanger (84) are configured to heat the circulating air, and thus can be referred to as a heater. The condenser 40 and the evaporating heat exchanger 81 are condensers because they are configured to condense the circulating air.

As described above, the air circulating unit 20 for circulating air including the drum in the heater dryer and the heat pump dryer can be said to be substantially the same. And the mechanism and structure for drying are very similar.

On the other hand, the spread of a dual type washing machine having two washing units in one washing machine is spreading.

The dual type washing machine is equipped with a large capacity washing machine and a washing machine having a relatively small capacity in a single washing machine.

The dual type washing machine may use one washing unit depending on the weight of the laundry or the type of laundry, or may divide the washing type according to the type of laundry and operate both washing units at the same time.

The present invention relates to a dual type dryer that can be used in pairs with a dual type washer.

An object of the present invention is to provide a dryer having a main drying unit having a relatively large capacity and an auxiliary drying unit having a relatively small capacity.

Another object of the present invention is to provide a dryer in which the main drying unit and the auxiliary drying unit are integrated into one cabinet and can be used independently.

Another object of the present invention is to provide a dryer in which laundry can be uniformly dried by controlling the air flow of the auxiliary drying unit.

To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a horizontal drum type main drying unit comprising: A cabinet type auxiliary drying unit disposed on an upper portion of the main drying unit and having an opening / closing door on an upper surface thereof; A cabinet for integrally enclosing the main drying unit and the auxiliary drying unit; And an operation panel disposed on a front surface of the auxiliary drying unit.

Preferably, the cabinet includes a side plate on both sides, and an intermediate plate that crosses between the main drying unit and the auxiliary drying unit and connects the side plates on both sides, and integrally integrates the main drying unit and the auxiliary drying unit to provide structural rigidity .

The side plate may be divided into a lower side plate corresponding to a side surface of the main drying unit and an upper side plate corresponding to a side surface of the auxiliary drying unit,

The auxiliary drying unit includes a laundry accommodating portion for providing a space for accommodating laundry, a blowing fan for introducing the outside air into the laundry accommodating portion, an electric heater for heating the air introduced into the laundry accommodating portion, A temperature sensor for measuring the temperature of the heated air, and a filter for blocking foreign substances contained in the outside air introduced into the laundry receiving portion.

It is preferable that the blowing fan, the electric heater, the temperature sensor, and the filter are disposed in a machine room behind the laundry receiving portion.

In this case, the rear surface of the auxiliary drying unit may protrude rearward from the rear surface of the main drying unit to have a stepped surface parallel to the bottom surface, and an inlet port for introducing outside air into the fan may be disposed on the stepped surface .

Preferably, the filter is disposed in parallel with the inlet of the intake passage, and the filter is detachably attachable to a rear surface of the laundry receiving portion, that is, a surface defining the rear of the laundry receiving portion. This surface is a position where the user can conveniently access from the front of the dryer through the laundry receiving portion provided in the upper portion of the dryer.

The opening / closing door of the auxiliary drying unit may include a first door hinged to a rear surface of the laundry receiving unit, and a second door hinged to the first door. Since the divided folding door structure is disposed on the main drying unit, it is possible to reduce the inconvenience of door opening and closing that may occur when a user having a small height is used.

The opening and closing door of the auxiliary drying unit may include sealing means for sealing the gap with the laundry receiving unit, and the sealing means may be provided in the entire area of the opening and closing door or only in a part of the area.

The auxiliary drying unit may further include an exhaust flow path for guiding the discharge of the air in the laundry accommodating portion. In this case, the inlet of the exhaust flow path and the outlet of the intake flow path may be arranged in different areas up and down (Arranged), and can be arranged in different areas in front and rear.

The dryer according to the present invention has a main drying unit for drying a large capacity and an auxiliary drying unit for drying a small capacity so that they can be operated simultaneously or individually according to the user's choice, . In addition, compared to conventional dryers, the operating panel is located at a more convenient location for the user to access and operate, while the auxiliary drying unit is installed, and the space in front of the auxiliary drying unit is utilized to increase the overall volume of the dryer The operation panel can be disposed at a position where the convenience can be enhanced.

In the dryer according to the present invention, the main drying unit is horizontally opened and closed in the form of a drum, and the auxiliary drying unit is opened and closed in a cabinet type so that the laundry can be easily inserted and withdrawn even if it is installed in a limited space.

Such a structure allows the user to independently use the main drying unit and the auxiliary drying unit, so that the drying unit more suitable for the weight of the laundry to be dried can be used in the two drying units depending on the weight of the laundry to be dried, So that the drying section can be selected. In the case of a laundry in which drum type drying is unsuitable, a cabinet type drying part can be used, and drying can be performed by separating into a main drying part and an auxiliary drying part depending on the characteristics of the laundry when drying a large amount of laundry.

In addition, the dryer according to the present invention prevents the wet steam discharged from the auxiliary drying unit from being discharged toward the user side, thereby preventing the user from feeling uncomfortable during use.

Further, the dryer according to the present invention is provided with a stand in the auxiliary dryer, and the heating air is caused to flow in the vertical direction of the stand, thereby improving the drying efficiency.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or preliminary meaning and the inventor shall properly define the concept of the term in order to describe its invention in the best possible way It should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention. It should be noted that the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, It should be understood that various equivalents and modifications are possible.

FIG. 5 is a schematic view showing a schematic configuration of a dual type dryer according to the present invention.

As shown, the dual-type dryer 1000 according to the present invention includes a main drying unit 100 having a relatively large capacity, an auxiliary drying unit 200 having a relatively small capacity, And a control panel 500 for operating the main drying unit 100 and the auxiliary drying unit 200. The cabinet 400 includes a cabinet 400 that surrounds the auxiliary drying unit 200,

It is preferable that the main drying unit 100 is a drum type for drying a large amount of laundry and has advantages in uniform drying of the laundry. However, the main drying unit of the present invention is not necessarily limited to the drum type.

It is preferable that the main drying unit 100 is a horizontal shaft drum type having an opening / closing door 120 on its front side, and the laundry is introduced and discharged through the front surface. However, the arrangement of the axes of the drums can be modified in various ways as long as the technical idea of the invention is not damaged.

The main drying unit 100 may be of a blowing type in which the circulating air is blown to the rear side or a suction type in which the circulating air is sucked in from the front side. Of course, the direction of the circulating air may be different. That is, the structure in which the circulating air moves from the front to the rear is also applicable.

The main drying unit 100 may be an electric heater, a heat pump, or a gas-type heater as a heating means.

The auxiliary drying unit 200 is disposed above the main drying unit 100.

The auxiliary drying unit 200 is provided with an opening / closing door 220 on the upper surface thereof to provide a structure in which the laundry is introduced and discharged through the upper surface.

The auxiliary drying unit 200 is preferably a cabinet type for drying laundry having a relatively small capacity.

In the cabinet type, the laundry is dried by supplying heated air to the inside of the laundry while the laundry is housed therein. By making the laundry accommodating space of a box having a low height, a uniform drying effect can be obtained as a whole.

Meanwhile, the auxiliary drying unit 200 may be provided with a holder 205 for hanging laundry. It is preferable that the cradle 205 is detachable. It is necessary to detach the cradle 205 in order to dry the thick laundry, and it is convenient to remove the cradle 205 when cleaning the inside of the cradle 205. In the illustrated embodiment, the cradle 205 has a grill net shape, but the cradle may be in the form of a perforated plate or screen net.

It is also possible to adjust the mounting height of the cradle 205. This may be accomplished by a structure in which a plurality of pedestals, which are slightly protruded from the inner wall of the auxiliary drying unit, are vertically spaced apart from each other, a cradle is guided by a rail extending in the vertical direction, Or may be a structure that can be fixed at an arbitrary position.

The opening / closing door 220 of the auxiliary drying unit 200 functions to open / close the upper opening surface of the laundry receiving unit 202. The opening and closing door 220 may include a first door 222 hinged to the rear of the laundry receiving portion 202 and a second door 224 hinged to the first door 222.

A structure in which the axes of the two hinges are arranged in parallel to each other and the first door 222 and the second door 224 are folded up in a folding manner is applied to increase the overall height when the opening and closing door 220 is opened So that the opening surface of the laundry receiving portion 202 can be completely opened.

At this time, it is preferable that at least the first door 222 is a transparent or translucent material. This is for checking the presence or absence of laundry in the interior of the first door 222 or checking the drying state.

The main drying unit 100 and the auxiliary drying unit 200 are configured to operate independently. That is, only the main drying unit 100 may be operated, or only the auxiliary drying unit 200 may be operated, and the main drying unit 100 and the auxiliary drying unit 200 may be operated at the same time.

For example, only the main drying unit 100 may be operated to dry a large amount of laundry, and only the auxiliary drying unit 200 may be operated to dry a small amount of laundry. When it is necessary to dry, some of the dried material is put into the auxiliary drying unit 200 and the remaining laundry is put into the main drying unit 100 and then both the auxiliary drying unit 200 and the main drying unit 100 are operated .

The operations of the main drying unit 100 and the auxiliary drying unit 200 are controlled by the operation panel 500.

The operation panel 500 is disposed above the front surface of the dryer 1000. When the operation panel 500 is disposed at the upper part of the front surface of the dryer 1000, the user accessibility is excellent and the operation state can be more easily confirmed.

Meanwhile, the operation panel 500 is connected to the main drying unit 100 by wiring, and is also connected to the auxiliary drying unit 200 by wiring.

However, both the main drying unit 100 and the auxiliary drying unit 200 are parts where heat is generated during operation. The distance between the wiring route and the wiring varies depending on the position of the operation panel 500.

In consideration of these points, the operation panel 500 is preferably disposed on the front side of the auxiliary drying unit 200.

The cabinet 400 forms an outer appearance of the main drying unit 100 and the auxiliary drying unit 200 and plays a role of securing the structural rigidity of the entire dryer 1000.

Since the front surface of the cabinet 400 occupies a large area occupied by the opening and closing door 120 of the main drying unit 100, it is desirable to secure the mechanical rigidity to the side panel.

6 is a view for explaining a cabinet structure of a dual type dryer according to the present invention.

The dual type dryer according to the present invention provides a structure in which the lower main drying unit 100 and the upper auxiliary drying unit 200 are integrated into the cabinet 400.

The cabinet 400 includes a base 450 to which a condenser and a drying fan of a lower main drying unit 100 are fixed and a base 450 that surrounds both sides of the main drying unit 100 and the auxiliary drying unit 200. And an intermediate plate 430 interposed between the main drying unit 100 and the auxiliary drying unit 200 and connecting the both side plates 410 and 420 to each other.

The main drying unit 100 has a box structure formed by the base 450, the side plates 410 and 420 and the intermediate plate 430. The auxiliary drying unit 200 has the two side plates 410 and 420, (430), the structural rigidity is secured by the U-shaped structure opened at the top.

The both side plates 410 and 420 may be divided into lower side plates 410a and 420b forming the side of the main drying unit 100 and upper side plates 410b and 420b forming the side of the auxiliary drying unit 200 have.

By dividing the side plate into the upper side plate and the lower side plate, it is possible to separate the manufacturing process of the main drying unit 100 and the manufacturing process of the auxiliary drying unit 200 in the manufacturing process and have the advantage that parts can be shared.

The dual type dryer according to the present invention has a structure in which the main drying part 100 at the lower part and the auxiliary drying part 200 at the upper part operate independently of each other and the main drying part 100 and the auxiliary drying part 200 The integration is accomplished by a cabinet.

When the side plates 410 and 420 are separated into the lower side plates 410a and 420a forming the side surfaces of the main drying unit 100 and the upper side plates 410a and 420a forming the side surfaces of the auxiliary drying unit 200, 100 and the assembling process of the auxiliary drying unit 200 can be independently separated.

For example, the main drying unit 100 is assembled in the form of a module with the base 450, the lower side plates 410a and 420a and the intermediate plate 430 as a skeleton, and the upper side plates 410b and 420b and the upper plate The auxiliary drying unit may be assembled in a module form, and then the assembled modules may be combined.

In this case, in the case of the front panel constituting the front surface of the dryer, a structure in which a single component is coupled in consideration of design and assembly can be applied. In the case of the side plate, the front side case forming the outer appearance of the front side is advantageously formed integrally without considering the design quality considering the relatively small amount of exposure to the outer side but forming the main appearance in the front side. Of course, also in the case of the front case, the main drying unit and the auxiliary drying unit can be divided.

In terms of assembly, it is possible to manufacture the main drying unit and the auxiliary drying unit in the form of a module, combining the main drying unit and the auxiliary drying unit, and assembling the integral front panel.

As described above, the main drying unit 100 and the auxiliary drying unit 200 are configured to operate independently. The main drying unit may be a drum type, and various types of heaters may be used. As the air circulation structure, a suction type or a blowing type Can be applied.

Hereinafter, various embodiments of the auxiliary drying unit of the dual type dryer according to the present invention will be described.

FIG. 7 is a perspective view for explaining an auxiliary drying unit according to the first embodiment of the present invention, FIG. 8 is a sectional view for explaining the internal structure of the auxiliary drying unit according to the first embodiment of the present invention, FIG. 3 is a view for explaining the air flow of the auxiliary drying unit according to the first embodiment of FIG.

Referring to FIG. 7, the auxiliary drying unit 200 of the dual type dryer according to the present invention is a cabinet type, and includes a laundry receiving unit 202 for receiving laundry, And a machine room M in which a blower fan 240, a drive motor 245, and an intake passage 250 are disposed.

The machine room M is preferably disposed behind the laundry receiving portion 202.

When the machine room M is disposed behind the laundry receiving portion 202, the user can access the laundry receiving portion 202 easily. It also has advantages in terms of design.

On the other hand, the rear surface of the machine room M of the auxiliary drying unit 200 may have a shape protruding rearward from the rear surface of the main drying unit. In other words, the rear surface of the auxiliary drying unit 200 protrudes rearward from the rear surface of the main drying unit 100. This shape can form a stepped surface MB at a lower portion of the machine room M. [ This stepped surface MB is opened toward the bottom surface even if the rear surface of the machine room is in close contact with the installation wall surface.

Therefore, if the inlet 252 is disposed on the stepped surface MB as in the illustrated embodiment, the outside air can flow smoothly through the inlet 252 even if the dryer is installed close to the wall surface.

In addition, due to such a structure, even when the dual type dryer is installed close to the installation wall, the rear surface of the main drying unit 100 can not be separated from the installation wall at a predetermined interval. This has the effect of smoothing the airflow to the rear surface of the main drying unit 100. [

8, a driving motor 245, a blowing fan 240, a heater 270, a temperature sensor 280, a filter 260, an intake passage 250 .

The blower fan 240 is rotated by the driving motor 245. The blowing fan 240 is disposed inside the intake passage 250 to flow air inside the intake passage 250.

When the blowing fan 240 rotates, the outside air is introduced into the intake passage 250 through the intake inlet 252, and then is discharged to the intake outlet 254. The intake port 254 is disposed on the rear surface of the laundry receiving portion 202. Therefore, the outside air is sucked by the operation of the blowing fan 240 and supplied to the laundry receiving portion 202.

The filter 260 is disposed on the downstream side of the intake port 252 on the intake path 250. The filter 260 functions to filter out foreign substances introduced together with the external air. The filter 260 is disposed behind the air inlet 252 rather than the air inlet 252 and is disposed upstream of the fan 240 and the heater 270 to prevent foreign matter or dust from adhering to the fan and the heater. The filter 260 is installed in a direction parallel to the intake port 252 of the intake passage 250.

The filter 260 needs maintenance such as cleaning or replacement at regular intervals. Therefore, in consideration of accessibility for maintenance, it is preferable that the filter 260 is detachably attachable through the rear surface of the laundry receiving portion 202.

A heater 270 and a temperature sensor 280 are disposed inside the intake passage 250.

The heater 270 is preferably an electric heater.

It is preferable to apply an electric heater rather than a gas type heater or a heat pump because a relatively small capacity of the auxiliary drying unit 200 is required. The electric heater is simple in structure and small in size, so that it has a small volume in the dryer and a low cost.

The temperature sensor 280 serves to measure the temperature of the air heated by the heater 270. The temperature sensor 280 is disposed behind the heater 270 on the air flow path to measure the temperature of the air passing through the heater 270 as a factor for controlling the heater and monitor whether the heater is overheated . That is, the temperature sensor 280 measures the temperature of the air flowing in the intake passage 250 and transmits the measured temperature to the controller. The controller adjusts the output of the heater 270 according to the temperature measured by the temperature sensor 280 So that air having a predetermined temperature can be supplied to the laundry receiving unit 202.

On the other hand, when the fan 240 or the drive motor 245 fails to smoothly flow air in the intake passage 250 due to damage or failure, it is feared that a failure or fire may occur due to overheating of the heater 270 . If the temperature measured by the temperature sensor 280 exceeds the reference value, the controller 270 turns off the power of the heater 270, displays an error message, and sounds an alarm. Thus, a visual and / or audible So that the user can be notified.

Referring to FIG. 9, an intake outlet 254 through which the heated air supplied from the machine room M flows is provided on a rear surface of the laundry receiving portion 202.

Preferably, the inlet 254 is disposed in the shape of a transverse slit on the rear surface of the laundry receiving portion 202.

In order to uniformly supply the heated air into the laundry receiving portion 202, the air inlet 254 is formed in a slit-like shape in the lateral direction .

The auxiliary drying unit 200 according to the present embodiment has a structure in which the air introduced into the laundry receiving unit 202 is discharged to the natural exhaust and does not have a separate exhaust flow path.

Air heated in the laundry accommodating portion 202 is introduced and the pressure inside the laundry accommodating portion 202 is increased so that air in the laundry accommodating portion 202 flows into the laundry accommodating portion 202 and the opening / And the like. At this time, it is preferable to provide a sealing means (226, thick line) for preventing natural exhaust from being performed on the front side. This is to prevent hot air from being discharged to the user when there is a user in front of the dryer.

In addition, the air discharged from the rear side of the air flow is moved forward due to the inertia, and the amount of ascending from the portion where the horizontal velocity due to inertia is lowered increases.

When the air that has risen from the front side is directly discharged to the natural exhaust, the heated air may not be smoothly supplied to the rear side.

Therefore, the sealing means 226 is applied to the front portion so that the air can be exhausted while being returned to the rear after reaching the front surface of the laundry receiving portion 202. Here, the front portion may be a portion of the second door 224 of the opening / closing door.

FIG. 10 is a configuration diagram showing an auxiliary drying unit according to a second embodiment of the present invention.

The auxiliary drying unit according to the second embodiment of the present invention is characterized in that two blowing fans 240 are provided to supply more heated air into the laundry receiving unit 202 and to supply the heated air evenly. The heater and the temperature sensor can be arranged downstream of each blowing fan. Of course, unlike the embodiment of the present invention, one blowing fan 240 may be formed long. However, in such a case, a structure for deflection phenomenon of the blowing fan 240 may additionally be required.

As shown in the drawing, a two-axis motor is used as the driving motor 245a, a blowing fan 240 is connected to both axes of the driving motor 245a, a driving motor 245a is provided in the center of the machine room, The heating air can be discharged from the entire rear surface of the laundry receiving portion 202 by being disposed on both sides with the driving motor interposed therebetween. In FIG. 10, a configuration in which one intake outlet 254 is provided in a form elongated laterally is exemplified. That is, one intake port 254 is shared by two blowing fans. However, it is also possible to adopt a structure in which the intake ports are provided one by one corresponding to the blowing fan.

Likewise, the intake ports may be shared by the two blowing fans, or may be arranged so that they are provided individually. If the intake inlet is provided as one, the filter can be made as one, and the filter can be cleaned easily.

FIG. 11 is a configuration diagram illustrating an auxiliary drying unit according to a third embodiment of the present invention.

The auxiliary drying unit 200 according to the third embodiment of the present invention further includes an exhaust flow passage 290 for guiding exhaust.

In this case, it is preferable that the upper opening of the laundry receiving portion 202 and the opening / closing door 220 are entirely sealed by sealing means.

The heated air has a flow rising due to natural convection so that the upper portion has a higher temperature distribution than the lower portion. The sealing means can reduce the discharge of heat to the upper side, thereby improving the drying efficiency.

As shown in the drawing, the inlet 254 may be disposed on the rear side of the laundry receiving portion 202 and the exhaust inlet 292 of the exhaust passage 290 may be disposed on the rear side of the laundry receiving portion 202.

The arrangement is such that the heated air discharged from the inflow outlet 254 pivots from the front surface of the laundry receiving portion 202 and is discharged to the exhaust inlet 292. However, in order to prevent the heated air introduced from the inflow outlet to the inside of the laundry receiving portion to immediately escape to the exhaust inlet, a blow-type air flow structure is applied rather than a suction type air flow, It is desirable to increase the discharge speed of air. It is also possible that a nozzle or vane structure is further provided near the inflow outlet to increase the air discharge speed at the inflow outlet and to enhance the straightness.

In the drawing, the exhaust outlet 294 of the exhaust passage 290 is disposed on the rear surface, but the exhaust outlet 294 may be disposed on the upper surface MS or on the stage surface MS.

In the illustrated embodiment, the inflow outlets 254 and the exhaust inlets 292 are arranged at different positions (diagonal positions) from top to bottom in the back, Or may be arranged in a form separated from left to right at a payout height.

When the inflow outlet 254 and the exhaust inlet 292 are divided vertically, the upper and lower divisions can be made based on the cradle (105 in FIG. 5).

This is to ensure that the flow of air inside is more effectively in contact with the surface of the laundry which is stationary.

It is to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and the scope of the present invention will be indicated by the appended claims rather than by the foregoing detailed description. It is intended that all changes and modifications that come within the meaning and range of equivalency of the claims, as well as any equivalents thereof, be within the scope of the present invention.
