Description

Clothes treating apparatus

Technical Field

The present invention relates to a laundry treating apparatus.

Background

In general, a laundry treating apparatus is an apparatus for treating various kinds of work with respect to laundry, and its concept encompasses a washing apparatus for washing laundry, a drying apparatus for drying wet laundry, a laundry care apparatus (refresher) for removing odor or wrinkles from laundry, and the like.

Some existing laundry treating apparatuses are designed to include: a drum providing a space for accommodating laundry; a driving unit that rotates the drum; and a supply part supplying steam or hot wind to the drum. In the laundry treating apparatus having the above-described structure, since steam or hot air needs to be supplied to the laundry while the drum is rotating (the laundry introduced into the drum is not in a flat state), wrinkles may be left in the laundry.

In order to solve the problems as described above, there is an existing laundry treating apparatus designed in such a manner that it includes: a box body; a first chamber provided inside the cabinet to provide a space for accommodating laundry; a second chamber provided inside the case to provide a space separated from the first chamber; a supply unit provided in the second chamber and supplying steam or hot air to the first chamber; a support body provided inside the first chamber to hang laundry inside the first chamber; and a driving part which moves the support main body inside the first chamber (granted patent No. 10-1674942).

The clothes treatment device with the structure can enable clothes in an unfolded state to shake in the first chamber, thereby solving the problem of the existing device (the problem that wrinkles are left on the clothes). However, there is a disadvantage in that vibration and noise may be generated due to the movement of the support portion.

Disclosure of Invention

An object of the present invention is to provide a laundry treating apparatus capable of removing wrinkles of a drying object such as laundry.

Another object of the present invention is to provide a laundry treating apparatus capable of minimizing vibration and noise.

The weight member may be constituted by a mass body in which a region of the driven portion on a side opposite to a side on which the arm projects is made heavier than a region on the same side as the side on which the arm projects.

The weight member may be a semicircular mass body or a fan-shaped mass body fixed to either one of an upper surface and a lower surface of the driven portion.

The weight may be formed of a mass body fixed to a circumferential surface of the driven portion.

The conversion part may include: a groove fixed to the support body at a lower portion of the arm; and a fastening part having one end fixed to the arm and the other end inserted into the groove; the groove may be disposed in a direction orthogonal with respect to a moving direction of the support body.

The length of the groove may be the same as the diameter of the rotation trajectory of the fastening part, or the length of the groove may be greater than the diameter of the rotation trajectory of the fastening part.

The driving part may be formed of a driving gear rotated by a motor, and the driven part may be formed of a driven gear rotated by the driving gear.

When the upper face of the driven gear is divided into a gear first region located at a side where the arm protrudes and a gear second region located at a side opposite to the side where the arm protrudes by using a straight line passing through the rotation center of the driven gear, the weight member may be disposed at the gear second region.

The content described in the present specification is not intended to limit the scope of the present invention. Like reference numerals refer to like parts throughout the specification.

As shown in fig. 1, the laundry treating apparatus 100 includes: a box body 1; a drying chamber 2 provided inside the cabinet and providing a space for accommodating drying objects such as laundry; and a support part 5 provided in the drying chamber 2, and capable of maintaining laundry in a spread state in the drying chamber 2.

As shown in fig. 2, the laundry treating apparatus 100 may be provided with: a first chamber 3 (mechanical chamber) located at a lower portion of the drying chamber 2; and a second chamber 4 located at an upper portion of the drying chamber 2.

The first chamber 3 and the second chamber 4 may be provided inside the casing 1 or outside the casing. Fig. 2 is a view showing an example in which the first chamber 3 is provided inside the casing 1 and is located at a lower portion of the drying chamber 2, and the second chamber 4 is provided inside the casing 1 and is located at an upper portion of the drying chamber 2. The first chamber and the second chamber may be provided to form a sealed space, or may be provided to form a space in which at least one surface is exposed to the outside.

One surface 11 (front surface) of the casing 1 may be provided with a first communication hole 111 communicating with the drying chamber 2 and a second communication hole 112 communicating with the first chamber 3 (see fig. 1). In the foregoing aspect 11, a door 13 is provided, and the door 13 may be provided so as to be able to open and close all of the first communication hole 111 and the second communication hole 112.

A control panel 14 may be provided at the door 13. The control panel 14 may be provided with: an input part for receiving a control command required for the operation of the laundry treatment apparatus 100 from a user; and a display unit for displaying the control command selectable by the user and the operation process of the control command selected by the user.

31, 32, 34, 35, and the

supply portions

31, 32, 34, 35 may supply at least one of air and moisture (steam, mist, or the like) to the drying chamber 2. A cover 113 may be provided to the second communication hole 112 to prevent the supply portion from being exposed to the outside (to prevent a safety accident) when the door 13 opens the first communication hole 111. The cover 113 (machine chamber door) is detachably fixed to the housing 1, and the cover 113 may be formed in any shape or structure as long as it can close the second communication hole 112.

The drying chamber 2 may include: a front chamber surface 21 provided with an inlet 211; an upper chamber surface 24 fixed to an upper end of the front surface of the chamber and forming an upper surface of the drying chamber; a chamber bottom surface 23 fixed to a lower end of the front surface of the chamber to form a bottom surface of the drying chamber; a chamber rear face 22 connecting the chamber upper face and the chamber bottom face, forming a rear face of the drying chamber.

The inlet 211 is provided to communicate with the first communication hole 111. Since the input port 211 is exposed to the outside of the cabinet when the door 13 opens the first communication hole 111, a user can input laundry into the drying chamber 2 or take laundry out of the drying chamber 2 through the input port 211.

The chamber bottom surface 23 may be provided as a wall (partition wall) that partitions the drying chamber 2 and the first chamber 3. The chamber bottom 23 may be provided with a discharge port 231, an air supply port 232, and a moisture supply port 233 for communicating the drying chamber 2 and the first chamber 3.

The exhaust port 231 may be a through hole that guides air inside the drying chamber 2 to the first chamber 3, and the air supply port 232 and the moisture supply port 233 may be provided as through holes that guide air and moisture supplied from the

supply parts

31, 32, 34, 35 to the drying chamber 2.

The

supply parts

31, 32, 34, 35 may include at least one of the air supply part 31 and the moisture supply part 34, and fig. 2 shows a case where the supply parts are all included including the air supply part 31 and the moisture supply part 34.

The air supply part 31 is a unit that supplies air to the drying chamber 2, and may include: a duct 311 connecting the discharge port 231 and the air supply port 232; and a fan 312 disposed inside the duct 311.

In the case where the air supply part 31 is provided to supply the heated air to the drying chamber 2, a heat exchange part 32 may be further provided inside the duct 311.

The heat exchanging portion 32 includes: a first heat exchanger 321 (evaporator) that condenses air by absorbing heat from the air flowing into the duct 311; and a second heat exchanger 322 (condenser) heating air by supplying heat to the air passing through the first heat exchanger. The first heat exchanger and the second heat exchanger are connected to each other by a refrigerant pipe 327 forming a refrigerant circulation flow path, and the refrigerant pipe 327 is provided with a compressor 325 for compressing refrigerant and a pressure regulator 326 for regulating the pressure of refrigerant circulating through the refrigerant pipe.

The moisture supply part 34 may include: a storage unit 341 that stores water; a heater 343 which is provided inside the storage unit and heats water; and a supply pipe 345 guiding the steam inside the storage part 341 to the moisture supply port 233. The heater 343 may be constituted by a resistor that generates heat when power is applied.

The storage part 341 may be provided to receive water from the water supply part 35 provided to the cover 113. That is, the water supply part 35 may include: a water tank 351 detachably provided to the cover 113 and storing water; a connection pipe 353 connecting the water tank 351 to the storage part 341; and a valve 356 controlling opening and closing of the connection pipe.

The support portion 5 is a unit for maintaining the laundry in a spread state inside the drying chamber 2. As shown in fig. 3, the support part 5 may include: a support body 51 positioned inside the drying chamber 2, the hanger H1 being placed on the support body 51; and a driving part D for supplying power required for the movement of the support body 51 inside the drying chamber 2.

The support body 51 may be a bar (bar) parallel to a width direction (Y-axis direction) of the drying chamber. The upper surface (the surface facing the upper surface of the chamber) of the support main 51 may be provided with a plurality of receiving grooves 513 for receiving the hooks H2 of the hangers.

One end of the support body 51 may be connected to the chamber upper surface 24 through a first connection body 511, and the other end of the support body 51 may be connected to the chamber upper surface 24 through a second connection body 512. Preferably, the first and second connecting

bodies

511 and 512 are made of an elastic material such as rubber so as to minimize the restriction of the movement of the supporting body 51 by the connecting bodies 511 and 512 (in order to minimize the power consumption of the driving part).

The first and second connecting

bodies

511 and 512 may be directly fixed to the chamber upper surface 24, or may be fixed to a fixing portion 52 provided in the second chamber 4. If the connecting

bodies

511 and 512 are not directly fixed to the chamber upper surface 24 but fixed to the fixing portion 52, vibration transmitted to the drying chamber 2 when the supporting body 51 moves (e.g., reciprocating motion parallel to the Y-axis direction) can be reduced.

When the connecting

bodies

511 and 512 are fixed to the fixing portion 52, the chamber upper surface 24 needs to be provided with a first through-hole 241 through which the first connecting body 511 passes and a second through-hole 242 through which the second connecting body 512 passes. Further, it is preferable that a gasket (gasset) is provided at each of the through

holes

241 and 242 to prevent the air or moisture supplied to the drying chamber 2 from being discharged to the second chamber 4. The shape or structure of the gasket may be differently set as long as it can block each through-hole.

The support body 51 is reciprocated inside the drying chamber 2 by the driving part D, and the term "reciprocation" used in the present specification includes not only a linear motion in which the support body reciprocates along the X-axis or the Y-axis but also a case in which the support body 51 performs a circular motion in the X-Y plane.

The driving part D may include: a driving part 54 provided with a motor 541; a driven part 55 provided with a rotating shaft 552 rotated by the power supplied from the driving part; and a conversion part 57 converting a rotational motion of the rotation shaft 552 into a reciprocating motion of the support main body 51.

The motor 541 of the driving part may be disposed to be fixed to the fixing part 52 to be located in the second chamber 4. A driving pulley 543 may be fixed to a rotation shaft 542 (motor shaft) of the motor.

The rotation shaft 552 of the driven portion is provided to penetrate the fixed portion 52 and the chamber upper surface 24. That is, the fixed portion 52 is provided with a fixed portion first through hole 521 through which the rotary shaft 552 passes, the chamber upper surface 24 is provided with an upper surface through hole, and the rotary shaft 552 is inserted into the fixed portion first through hole 521 and the upper surface through hole, and has one end positioned in the drying chamber 2 and the other end positioned in the second chamber 4.

The driven portion 55 is provided with a driven pulley 551 and an arm 553 fixed to both ends of the rotating shaft 552. The driven pulley 551 is fixed to one end of the rotary shaft 552 at the second chamber 4, and the arm 553 is fixed to one end of the rotary shaft 552 at the drying chamber 2. As shown in fig. 4, the arm 553 may be formed of a rod (bar) having one end (fixed end) fixed to the rotation shaft 552.

As shown in fig. 3, the driving pulley 543 and the driven pulley 551 are connected by a belt 56. Accordingly, as shown in fig. 4, when the motor shaft 542 rotates, the free end of the arm 553 fixed to one end of the rotation shaft 552 rotates inside the drying chamber 2.

Unlike the drawings, the driving pulley 543 may be replaced with a driving gear, and the driven pulley 551 may be replaced with a driven gear. In this case, the driving gear and the driven gear need to be engaged with each other (a belt is an unnecessary structure).

The conversion section 57 may include: a groove 573 fixed to the support body 51 at a lower portion of the arm 553; and a fastening portion 571 having one end fixed to the arm 553 and the other end (free end) inserted into the groove 573.

As shown in fig. 4, the grooves 573 may be provided in a direction (X-axis direction) orthogonal to the support body 51. In this case, the movement of the support body 51 depends on the length of the groove 573 and the diameter of the rotation trajectory T formed when the fastening portion 571 rotates.

That is, if the length L of the grooves 573 is set to be equal to or greater than the diameter of the rotation locus T of the fastening part 571, the support body 51 makes a linear reciprocating motion in the width direction (Y-axis direction) of the drying chamber 2 when the arm 553 rotates. If the fastening part 571 moves along the rotation locus T, a resultant force F of a force a orthogonal to the component of the groove and a force B parallel to the component of the groove acts on the groove 573. However, if the diameter L of the groove is equal to or greater than the diameter of the rotation trajectory T, the support body 51 is moved only by the force a orthogonal to the components of the groove, and thus, the support body 51 is linearly reciprocated along the Y-axis under the rod as in fig. 4.

On the other hand, if the length L of the groove 573 is set to be smaller than the diameter of the rotation trajectory T of the fastening part 571, the support body 51 performs a reciprocating motion forming an elliptical trajectory in the X-Y plane when the arm 553 rotates.

Unlike the drawing, the grooves 573 may also be provided in a direction (Y-axis direction) parallel to the support body 51. In this case, if the length L of the groove 573 is set to be equal to or greater than the diameter of the rotation locus T of the fastening part 571, the support body 51 can linearly reciprocate in the depth direction (X-axis direction) of the drying chamber 2 when the arm 553 rotates (preferably, the positions of the connection body and the through-hole are changed). However, if the length L of the groove 573 is set to be smaller than the diameter of the rotation trajectory T of the fastening part 571, the support body 51 performs a reciprocating motion forming an elliptical trajectory in the X-Y plane when the arm 553 rotates.

The laundry treating apparatus 100 having the above-described structure may separate dust such as particles of bad smell from the laundry received in the drying chamber 2 by shaking the support main body 51 when the rotation shaft 552 rotates. In addition, if the supporting body 51 is shaken during the supply of air or moisture through the

supply parts

31, 32, 34, 35, an effect of removing wrinkles generated on the laundry may also be expected.

However, the laundry treating apparatus 100 configured only by the above-described structure may have a problem in that the vibration of the drying chamber 2 increases as the reciprocating period of the supporting body 51 becomes smaller. In order to minimize the vibration of the drying chamber 2 caused by the movement of the support main body 51, a vibration control part 6 for suppressing the vibration caused by the support main body 51 may be further provided at the support part 5.

As described with reference to fig. 5, the vibration control unit 6 may be configured by a weight (weight) fixed to the driven unit 55 so as to be positioned on a side (+ Y-axis direction) opposite to a side (Y-axis direction) on which the arm 553 protrudes from the rotary shaft 552.

The weight member may be constituted by a mass body in which a region R2 on the opposite side (+ Y-axis direction) to the side where the arm protrudes in the region of the driven pulley 551 has a weight larger than a region R1 on the side where the arm protrudes (-Y-axis direction).

That is, when the upper face of the driven pulley 551 is divided into a pulley first region R1 located at a side where the arm protrudes and a pulley second region R2 located at a side opposite to the side where the arm protrudes by a straight line passing through the rotation center 552 of the driven pulley, the weight member may be disposed at the pulley second region R2.

When the vibration control portion 6 as described above is provided at the driven pulley 551, the vibration generated when the support body 51 reciprocates overlaps with the vibration generated when the weight block rotates (overlap that attenuates a part of the vibration caused by the support body is generated). If the vibration caused by the supporting body 51 and the vibration caused by the weight are overlapped, the maximum amplitude of the supporting body 51 can be reduced, and thus the laundry treating apparatus 100 provided with the vibration control part 6 can minimize the vibration of the drying chamber 2 and the cabinet 1.

The weight may be a semicircular or fan-shaped mass fixed to either the upper or lower surface of the driven pulley 551, and fig. 5 shows an example of a semicircular mass fixed to the upper surface of the driven pulley 551.

Unlike the drawings, the weight member may be a mass fixed to the circumferential surface of the driven pulley 551. In this case, the weight may be composed of a mass body fixed to a region (pulley circumferential surface second region) forming an edge of the pulley second region R2 among circumferential surfaces (pulley circumferential surface first region, pulley circumferential surface second region) of the driven pulley 551.

On the other hand, even when the driving portion 54 is provided with a driving gear and the driven portion 55 is provided with a driven gear, the weight needs to be fixed in the gear second region. That is, when the upper face of the driven gear is divided into a gear first region located on the side where the arm protrudes and a gear second region located on the side opposite to the side where the arm protrudes by a straight line passing through the rotation center of the driven gear, the weight block needs to be fixed to the gear second region.

Further, when the circumferential surface of the driven gear is divided into a first region of the circumferential surface of the gear located on the side where the arm protrudes and a second region of the circumferential surface of the gear located on the opposite side to the side where the arm protrudes by a straight line passing through the rotation center of the driven gear, the weight may be provided in the second region of the circumferential surface of the gear.

The present invention may be modified in various forms, and therefore the scope of the present invention is not limited to the above embodiments.
