Hereinafter, operation principles and various embodiments of the disclosure will be described with reference to accompanying drawings.
A clothes care apparatus 1 according to an embodiment of the disclosure may be an apparatus for taking care of a target. For example, the target may include clothes, shoes, or the like.
An accommodating chamber 20 in which the target is accommodated may be provided at an upper part of the clothes care apparatus 1. A machine room 30 where various devices used to generate high-temperature heat for taking care of the target are installed may be provided at a lower part of the accommodating chamber 20. The accommodating chamber 20 and the machine room 30 may be separated from each other.
A heat pump apparatus 40 for supplying high-temperature dry air to the accommodating chamber 20 may be arranged inside the machine room 30. The heat pump apparatus 40 may dehumidify and heat air circulating the accommodating chamber 20. The heat pump apparatus 40 may supply the heated air into the accommodating chamber 20.
Also, a condensed water collecting apparatus 50 configured to collect condensed water generated from the heat pump apparatus 40 may be arranged inside the machine room 30. The condensed water formed on an outer surface of the heat pump apparatus 40 may be collected in the condensed water collecting apparatus 50 through a drain 80.
The heat pump apparatus 40 may include a refrigerant pipe 45 for transmitting a refrigerant circulating the heat pump apparatus 40. The refrigerant circulating through the refrigerant pipe 45 may exchange heat with the air of the accommodating chamber 20, passing through a heat exchanger. For example, the refrigerant circulating the refrigerant pipe 45 may absorb heat while being evaporated in the heat exchanger, thereby dehumidifying the air of the accommodating chamber 20, and may emit heat while being condensed in the heat exchanger, thereby heating the air of the accommodating chamber 20. Accordingly, a refrigerant of a high-temperature state may flow in at least one flow path among the refrigerant pipe 45 of the heat pump apparatus 40, and a refrigerant of a low-temperature state may flow in at least another flow path among the refrigerant pipe 45.
In the clothes care apparatus 1 according to an embodiment of the disclosure, the at least one flow path for transmitting the refrigerant of the high-temperature state among the refrigerant pipe 45 may be provided to pass through the condensed water collecting apparatus 50. The at least one flow path where a high-temperature refrigerant flows may have a high temperature according to heat conduction. The refrigerant pipe 45 of a high temperature passes through a storage space of the condensed water stored in the condensed water collecting apparatus 50, and thus the condensed water may be heated and an evaporation rate of the condensed water may be increased. Accordingly, the refrigerant pipe 45 of the high temperature may operate as a condensed water heating apparatus configured to heat the condensed water stored in the condensed water collecting apparatus 50.
The clothes care apparatus 1 according to an embodiment of the disclosure may heat and evaporate the condensed water by at least one flow path among the refrigerant pipe 45, and thus a process by which a user periodically discharges the condensed water may be omitted. Accordingly, user convenience may be improved. Also, a portion of the refrigerant pipe 45 is used as the condensed water heating apparatus, and thus a pipe for externally discharging the condensed water stored in the condensed water collecting apparatus 50 may not be necessary.
In the disclosure, the clothes care apparatus 1 may correspond to, for example, a dryer, a steam closet, a shoe care apparatus, a clothes wrinkle removing apparatus, or an ironing apparatus.

The heat pump apparatus 40 may include a compressor 41, an evaporator 42, a condenser 43, an expansion apparatus 44, and the refrigerant pipe 45. The compressor 41, evaporator 42, condenser 43, and expansion apparatus 44 are connected to each other through the refrigerant pipe 45 such that a flow path in which the refrigerant circulates is formed. The refrigerant may circulate according to a cycle of the heat pump apparatus 40 while flowing through the refrigerant pipe 45. The heat pump apparatus 40 may dehumidify and heat the air circulating the accommodating chamber 20.
The compressor 41 may adiabatically compress a sucked up gas-phase refrigerant, thereby discharging a high-temperature and high-pressure gas-phase refrigerant. The compressor 41 may include an inverter circuit capable of controlling a driving frequency, and may increase or decrease (change) compression capability, based on an input signal from the processor 110.
The evaporator 42 is a heat exchanger and may exchange heat with the air in the accommodating chamber 20. The air in the accommodating chamber 20 may pass through the evaporator 42 to exchange heat with the refrigerant. The refrigerant may absorb heat of ambient air while being evaporated in the evaporator 42. The air that passes through the evaporator 42 may be cooled down and at the same time, dehumidified, and thus become dry air.
The condenser 43 is a heat exchanger and may exchange heat with the air in the accommodating chamber 20. The air in the accommodating chamber 20 may pass through the condenser 43 to exchange heat with the refrigerant. The refrigerant may emit heat to the ambient air while being condensed in the condenser 43. The air that passes through the condenser 43 may be heated and become high-temperature air.
The expansion apparatus 44 may discharge the decompressed refrigerant by adiabatically expanding the introduced refrigerant.
The refrigerant pipe 45 may circulate the refrigerant by connecting the compressor 41, the evaporator 42, the condenser 43, and the expansion apparatus 44 to each other.

The condensed water collecting apparatus 50 may collect the condensed water generated from the heat pump apparatus 40. The condensed water is water condensed on an outer surface of the evaporator 42, and may be collected in the condensed water collecting apparatus 50 through a drain. According to an embodiment of the disclosure, the condensed water stored in the condensed water collecting apparatus 50 may be heated and evaporated by at least one flow path in a high-temperature state, and thus the condensed water collecting apparatus 50 may not need to be detached from the clothes care apparatus 1.
The processor 110 may generate a control signal for controlling operations of the clothes care apparatus 1. The processor 110 may process data according to a program, instruction, and data stored in a memory, and generate the control signal according to a result of the processing. For example, when a user inputs a command of selecting an operating course, the clothes care apparatus 1 may perform target care corresponding to the selected operating course. The processor 110 may control the heat pump apparatus 40 for the target care.
Referring to
In operation S310, the processor 110 may receive selection on an operating course for taking care of a target in the accommodating chamber 20.
When a user inputs a command of selecting an operating course, the processor 110 may process data according to the selection on the operating course and generate a control signal according to a result of the processing. For example, the operating course may be selected differently according to a clothes type or a shoe type. The operating courses may include a standard course, a quick course, a power course, a clean storage course, and the like.
In operation S320, the processor 110 may control the heat pump apparatus 40 connected to the refrigerant pipe 45 in which a refrigerant circulates, and including the compressor 41, the condenser 43, the expansion apparatus 44, and the evaporator 42, based on the selected operating course.
The processor 110 may control the heat pump apparatus 40 to operate according to the selected operating course. Accordingly, the refrigerant may circulate through the refrigerant pipe 45 of the heat pump apparatus 40. For example, the processor 110 may operate in a condensed water heating state for heating condensed water stored in the condensed water collecting apparatus 50, by at least one flow path passing through the condensed water collecting apparatus 50 among the refrigerant pipe 45.
When a time of the selected operating course is completed, the processor 110 may control the heat pump apparatus 40 not to operate. Accordingly, the refrigerant may not circulate through the refrigerant pipe 45 of the heat pump apparatus 40. For example, the refrigerant of a high-temperature state does not flow in the at least one flow path passing through the condensed water collecting apparatus 50 among the refrigerant pipe 45, and thus the at least one flow path may not be used as a condensed water heating apparatus. At this time, the processor 110 may operate in a condensed water heating stopped state.
Also, when the time of the selected operating course is temporarily stopped, the processor 110 may control the heat pump apparatus 40 not to operate. Accordingly, the processor 110 may operate in the condensed water heating stopped state as described above.
Referring to
The compressor 41, the condenser 43, the expansion apparatus 44, and the evaporator 42 are sequentially connected by the refrigerant pipe 45 such that a flow path in which a refrigerant circulates is formed. The compressor 41, the condenser 43, the expansion apparatus 44, the evaporator 42, and the refrigerant pipe 45 may configure the heat pump apparatus 40.
The compressor 41 and the expansion apparatus 44 may be spatially separated from the evaporator 42 and the condenser 43. The compressor 41 and the expansion apparatus 44 may be arranged outside an air passage 32, and the evaporator 42 and the condenser 43 may be arranged inside the air passage 32. The air passage 32 may be connected to the accommodating chamber 20 through an air vent 31 (see
The refrigerant pipe 45 may include a first flow path 45a, a second flow path 45b, a third flow path 45c, and a fourth flow path 45d. The first flow path 45a may connect the condenser 43 to the compressor 41. The second flow path 45b may connect the expansion apparatus 44 to the condenser 43. The third flow path 45c may connect the evaporator 42 to the expansion apparatus 44. The fourth flow path 45d may connect the compressor 41 to the evaporator 42.
The compressor 41 may be arranged in a hermetic space inside the machine room 30, which is outside the air passage 32. The compressor 41 may transmit the refrigerant to the condenser 43 through the first flow path 45a, and receive the refrigerant from the evaporator 42 through the fourth flow path 45d.
The evaporator 42 may be arranged inside the air passage 32, and may be arranged in a first direction (for example, X-axis direction) with the condenser 43. The evaporator 42 may transmit the refrigerant to the compressor 41 through the fourth flow path 45d, and receive the refrigerant from the expansion apparatus 44 through the third flow path 45c.
The condenser 43 may be arranged inside the air passage 32. The condenser 43 may transmit the refrigerant to the expansion apparatus 44 through the second flow path 45b, and receive the refrigerant from the compressor 41 through the first flow path 45a.
The expansion apparatus 44 may be arranged in the hermetic space in the machine room 30, which is outside the air passage 32. The expansion apparatus 44 may transmit the refrigerant to the evaporator 42 through the third flow path 45c, and receive the refrigerant from the condenser 43 through the second flow path 45b.
The condensed water collecting apparatus 50 may be arranged below the machine room 30. The condensed water collecting apparatus 50 may store the condensed water collected through the drain 80 connected to the outside of the evaporator 42. The condensed water collecting apparatus 50 may be formed in various types to increase an evaporation amount of the condensed water. For example, the condensed water collecting apparatus 50 may be formed to have a wide surface area within a range that does not reach the compressor 41. The wider the surface area of the condensed water collecting apparatus 50, the greater the evaporation amount of the condensed water, because a surface area of the stored condensed water is increased. As another example, the condensed water may be exposed by not providing an upper cover of the condensed water collecting apparatus 50. Accordingly, the evaporation amount of the condensed water may be increased.
According to an embodiment of the disclosure, a process of discharging the condensed water of the condensed water collecting apparatus 50 is omitted, and thus the condensed water collecting apparatus 50 may not need to be detached, or may not need to be detachable, from the clothes care apparatus 1. However, an embodiment of the disclosure is not limited thereto, and the condensed water collecting apparatus 50 may be detached from the clothes care apparatus 1.
The air circulation fan 70 may be arranged in the air passage 32. The air circulation fan 70 may be arranged in the first direction (the X-axis direction) with the evaporator 42 and the condenser 43. The air circulation fan 70 may suck up air introduced to the air passage 32 through the air vent 31, and discharge the air that has passed through the evaporator 42 and the condenser 43 to the accommodating chamber 20 again. The air introduced from the accommodating chamber 20 through the air vent 31 may be dried while passing through the evaporator 42 of the heat pump apparatus 40, heated while passing through the condenser 43, and discharged to the accommodating chamber 20 again. The air circulation fan 70 may circulate an internal air current of the accommodating chamber 20.
In the clothes care apparatus 1 according to an embodiment of the disclosure, the first flow path 45a among the refrigerant pipe 45 may be provided to pass through the inside of the condensed water collecting apparatus 50. The first flow path 45a may pass through a condensed water storage space of the condensed water collecting apparatus 50, and correspond to a condensed water heating apparatus configured to heat the stored condensed water.
As will be described in
For example, the first flow path 45a may extend in the first direction (the X-axis direction) and then extend in a second direction (a Z-axis direction) that is perpendicular to the first direction (the X-axis direction) towards the condensed water collecting apparatus 50. The first flow path 45a may be provided to pass through the condensed water storage space of the condensed water collecting apparatus 50. The portion of the first flow path 45a, which passes through the condensed water storage space of the condensed water collecting apparatus 50, may have a winding shape. Accordingly, a surface area of the first flow path 45a, which contacts the condensed water, may be increased, and thus heating and evaporating of the condensed water by the first flow path 45a may be accelerated.

The accommodating chamber 20, the heat pump apparatus 40, the condensed water collecting apparatus 50, and the processor 110 of the clothes care apparatus 1 have been described above with reference to
The forced air current generating apparatus 60 may be a fan that generates a forced air current in the condensed water collecting apparatus 50. The forced air current generating apparatus 60 may rotate based on a set rotate-per-minute (RPM). The forced air current generating apparatus 60 may increase an air current speed of a surface of the condensed water by generating the forced air current on the surface of the condensed water stored in the condensed water collecting apparatus 50. When the air current speed of the surface of the condensed water is increased, the evaporation amount of the condensed water may be increased. The forced air current generating apparatus 60 may be arranged to face the surface of the condensed water stored in the condensed water collecting apparatus 50, and accelerate evaporation of the condensed water.
The clothes care apparatus 1 according to an embodiment of the disclosure may improve an evaporation rate of the condensed water stored in the condensed water collecting apparatus 50 by including the forced air current generating apparatus 60 and the refrigerant pipe 45 in a high-temperature state, which corresponds to the condensed water heating apparatus.
In general, the evaporation rate is defined by an amount of water evaporated per hour. The evaporation rate may be proportional to an air current speed v around a water surface and proportional to a surface area of water. Also, the evaporation rate may increase as a temperature Twater of water is increased.
According to an embodiment of the disclosure, through an operation of the heat pump apparatus 40, a temperature of the condensed water may be increased through the refrigerant pipe 45 operating as the condensed water heating apparatus, and air flow may be induced around a surface of the condensed water through the forced air current generating apparatus 60. The forced air current generating apparatus 60 may increase the air current speed around the surface of the condensed water. In this case, the evaporation rate of the condensed water may be increased up to 10 times to 20 times compared to a natural evaporation rate, wherein there is no flow in ambient air of the surface of the condensed water and a temperature is similar to a temperature inside the machine room 30. For example, when the natural evaporation rate is about 10 g/h, the increased evaporation rate may be 100 g/h to 200 g/h.
The air circulation fan 70 may be provided between the heat pump apparatus 40 and the accommodating chamber 20 to circulate air. The air circulation fan 70 may rotate based on a pre-determined RPM. The air circulation fan 70 may suck up air introduced from the accommodating chamber 20 through to the air vent 31, and discharge the air that has passed through the heat pump apparatus 40 to the accommodating chamber 20 again.
The temperature sensor 120 may be variously arranged in the machine room 30, and measure an ambient temperature of the temperature sensor 120. For example, the temperature sensor 120 may be arranged close to the condensed water collecting apparatus 50 and measure an ambient temperature of the condensed water stored in the condensed water collecting apparatus 50. Information about the ambient temperature measured by the temperature sensor 120 may be transmitted to the processor 110. The processor 110 may operate in any one of various operating modes according to the ambient temperature measured by the temperature sensor 120. The processor 110 may control the heat pump apparatus 40 according to the operating mode. For example, the processor 110 may operate in a low-temperature mode, a room-temperature mode, or a high-temperature mode according to the ambient temperature.
The humidity sensor 130 may be variously arranged in the machine room 30, and measure ambient humidity of the humidity sensor 130. For example, the humidity sensor 130 may be arranged close to the condensed water collecting apparatus 50 and measure ambient humidity of the condensed water stored in the condensed water collecting apparatus 50. Information about the ambient humidity measured by the humidity sensor 130 may be transmitted to the processor 110. The processor 110 may operate in any one of various operating modes according to the ambient humidity measured by the humidity sensor 130. The processor 110 may control the heat pump apparatus 40 according to the operating mode.
The water level sensor 140 may measure a collected amount of the condensed water stored in the condensed water collecting apparatus 50. Information about the collected amount measured by the water level sensor 140 may be transmitted to the processor 110. The processor 110 may operate in any one of various operating modes according to the collected amount measured by the water level sensor 140. The processor 110 may control the heat pump apparatus 40 according to the operating mode. For example, the processor 110 may operate in an energy-saving mode, a basic mode, a condensed water overload operation, and an emergency operation, according to the measured collected amount.
The processor 110 may control the heat pump apparatus 40 and control the forced air current generating apparatus 60, according to the collected amount of the condensed water collecting apparatus 50, which is measured through the water level sensor 140. For example, when the collected amount is high, the heat pump apparatus 40 and the forced air current generating apparatus 60 may be controlled to be operated. For example, when the collected amount is low, the heat pump apparatus 40 may be controlled to be operated and the forced air current generating apparatus 60 may be controlled to be not operated. Various examples of a control method for the clothes care apparatus 1 will be described below with reference to

The heat pump apparatus 40 includes the compressor 41, the condenser 43, the expansion apparatus 44, and the evaporator 42. The compressor 41, the condenser 43, the expansion apparatus 44, and the evaporator 42 may be connected to each other by the refrigerant pipe 45 to configure a heat pump cycle. The refrigerant may circulate according to the heat pump cycle while flowing through the refrigerant pipe 45.

The compressor 41 compresses the gas-phase refrigerant of a low temperature and low pressure, which flows through the fourth flow path 45d, and discharges the gas-phase refrigerant of a high temperature and high pressure. The discharged gas-phase refrigerant of the high temperature and high pressure is introduced to the condenser 43 through the first flow path 45a, and the gas-phase refrigerant of the high temperature and high pressure may be condensed to the liquid-phase or near-liquid-phase refrigerant of high pressure, which is equal to or less than the condensation temperature, by the condenser 43. The liquid-phase or near-liquid-phase refrigerant of the high pressure, which flows through the second flow path 45b after passing through the condenser 43, is decompressed through the expansion apparatus 44, and the two-phase refrigerant of a low temperature and low pressure, which passed through the expansion apparatus 44, is introduced to the evaporator 42 through the third flow path 45c. In the evaporator 42, the two-phase refrigerant may be evaporated to the gas-phase refrigerant. The gas-phase refrigerant may be discharged from the evaporator 42 through the fourth flow path 45d.
High-temperature humid air in the accommodating chamber 20 may exchange heat with the two-phase refrigerant of the low temperature and low pressure while passing through the evaporator 42. In detail, the two-phase refrigerant of the low temperature and low pressure, which is introduced to the evaporator 42 through the third flow path 45c, may absorb heat from the high-temperature humid air passing through the evaporator 42 and be evaporated as the gas-phase refrigerant, and the high-temperature humid air that passes through the evaporator 42 is cooled down and at the same time, dehumidified to become low-temperature dry air. The gas-phase refrigerant discharged from the evaporator 42 may flow through the fourth flow path 45d.
The low-temperature dry air that passed through the evaporator 42 may be introduced to the condenser 43, and the gas-phase refrigerant of the high temperature and high pressure and the low-temperature dry air may exchange heat in the condenser 43. In detail, the gas-phase refrigerant of the high temperature and high pressure, which is introduced to the condenser 43 through the first flow path 45a, may emit heat while being condensed to the liquid-phase or near-liquid-phase refrigerant, and the low-temperature dry air may be heated by absorbing the heat emitted during a refrigerant condensation process. The gas-phase refrigerant discharged from the condenser 43 may flow through the second flow path 45b.
According to an embodiment of the disclosure, the first flow path 45a that transmits, to the condenser 43, the gas-phase refrigerant of the high temperature and high pressure, which is discharged from the compressor 41, may be provided to pass through the inside of the condensed water collecting apparatus 50. When the first flow path 45a is provided to pass through the inside of the condensed water collecting apparatus 50, the heating of the condensed water stored in the condensed water collecting apparatus 50 may be accelerated, thereby increasing the evaporation amount of the condensed water.
The processor 110 may control the heat pump apparatus 40 to operate according to the operating course. When the heat pump apparatus 40 operates, the first flow path 45a may be used as the condensed water heating apparatus for heating the condensed water of the condensed water collecting apparatus 50, and thus the processor 110 may operate in the condensed water heating state.
Also, the processor 110 may control the heat pump apparatus 40 not to operate when a time of the operating course is completed or the operating course is temporarily stopped. When the heat pump apparatus 40 does not operate, the first flow path 45a is not used as the condensed water heating apparatus, and thus the processor 110 may operate in the condensed water heating stopped state.
The temperature sensor 120, the humidity sensor 130, and the water level sensor 140 may each be provided near the condensed water collecting apparatus 50.
Hereinafter, another example of the clothes care apparatus 1 according to an embodiment of the disclosure will be described with reference to
Referring to
The second flow path 45b-1 may pass through the condensed water storage space of the condensed water collecting apparatus 50, and correspond to the condensed water heating apparatus configured to heat the stored condensed water. The second flow path 45b-1 may be a refrigerant pipe that transmits the liquid-phase or near-liquid-phase refrigerant of high pressure, which is equal to or less than the condensation temperature, discharged from the condenser 43, to the expansion apparatus 44. A temperature of the refrigerant flowing through the second flow path 45b-1 may be lower than a temperature of the refrigerant flowing through a first flow path 45a-1, but may be higher than a temperature of the refrigerant flowing through the third flow path 45c or fourth flow path 45d. In other words, the second flow path 45b-1 may transmit the refrigerant of a relatively high temperature. For example, the temperature of the refrigerant flowing through the second flow path 45b-1 may be higher than a room temperature, but is not limited thereto.
When the clothes care apparatus 1 operates according to an operating mode, the refrigerant circulates through the refrigerant pipe 45 of the heat pump apparatus 40, and because the second flow path 45b-1 transmits the refrigerant of the relatively high temperature, the second flow path 45b-1 may itself be a pipe in a high-temperature state. A portion of the second flow path 45b-1, which passes through the condensed water storage space of the condensed water collecting apparatus 50, may heat and evaporate the condensed water with high-temperature heat.
For example, the second flow path 45b-1 may extend in the first direction (the X-axis direction) near a discharge port of the condenser 43 and a discharge port of the expansion apparatus 44, and then extend in the second direction (the Z-axis direction) perpendicular to the first direction (the X-axis direction) towards the condensed water collecting apparatus 50. The second flow path 45b-1 may be provided to pass through the condensed water storage space of the condensed water collecting apparatus 50. The portion of the second flow path 45b-1 which passes through the condensed water storage space of the condensed water collecting apparatus 50, may have a winding shape. Accordingly, a surface area of the second flow path 45b-1, which contacts the condensed water, may be increased, and thus heating and evaporating of the condensed water by the second flow path 45b-1 may be accelerated.
Meanwhile, according to an embodiment of the disclosure, the first flow path 45a-1 does not extend towards the condensed water collecting apparatus 50, and does not pass through the condensed water collecting apparatus 50, but is not limited thereto. For example, the first flow path 45a-1 may be provided to pass through the condensed water collecting apparatus 50, like the first flow path 45a of
Hereinafter, a control method for the clothes care apparatus 1, according to a value measured by the water level sensor 140, according to an embodiment of the disclosure, will be described with reference to
Referring to
For example, the water level sensor 140 may transmit, to the processor 110, information about the measured collected amount. Upon receiving the measured collected amount, the processor 110 may compare the collected amount with a first reference water level A, a second reference water level B, or a threshold water level C. The processor 110 may control the operating mode of the clothes care apparatus 1, based on a result of comparing the collected amount with the first reference water level A, the second reference water level B, or the threshold water level C. For example, the operating mode may be one of the energy-saving mode, the basic mode, the condensed water overload operation, and the emergency operation.
According to an embodiment of the disclosure, the second reference water level B may be lower than the threshold water level C and higher than the first reference water level A. For example, the threshold water level C is a maximum water level of the condensed water accommodatable in the condensed water collecting apparatus 50, and when the collected amount is equal to or greater than the threshold water level C, the condensed water may overflow from the condensed water collecting apparatus 50. As another example, the threshold water level C may be present outside the condensed water collecting apparatus 50, and detect the condensed water overflowing from the condensed water collecting apparatus 50.
The processor 110 may normally operate the operating course of the clothes care apparatus 1 or temporarily stop the operating course, according to the operating mode. Also, the processor 110 may operate in the condensed water heating state or the condensed water heating stopped state, according to the operating mode. Also, the processor 110 may turn on or off power of the forced air current generating apparatus 60, according to the operating mode.
According to an embodiment of the disclosure, in response to determining that the collected amount is less than the first reference water level A, the processor 110 may control the clothes care apparatus 1 to be in the energy-saving mode. In the energy-saving mode, the processor 110 may control an operation of the heat pump apparatus 40 according to the selected operating course. In other words, the processor 110 may control the heat pump apparatus 40 to operate so as to be normally operated according to the selected operating course of the clothes care apparatus 1.
In the energy-saving mode, the processor 110 may operate in the condensed water heating state as the heat pump apparatus 40 is operated. In the condensed water heating state, at least one flow path, which transmits a refrigerant of a high-temperature state, among the refrigerant pipe 45, may pass through the inside of the condensed water collecting apparatus 50, thereby heating the condensed water. Also, the processor 110 may turn off the power of the forced air current generating apparatus 60. When it is determined that the water level of the collected condensed water is less than the first reference water level A, the processor 110 may control the forced air current generating apparatus 60 not to operate for energy saving. The condensed water less than the first reference water level A may be heated and evaporated by at least one flow path operating as the condensed water heating apparatus.
According to an embodiment of the disclosure, in response to determining that the collected amount is equal to or greater than the first reference water level A and less than the second reference water level B, the processor 110 may control the clothes care apparatus 1 to be in the basic mode. In the basic mode, the processor 110 may control the heat pump apparatus 40 to operate according to the selected operating course. The processor 110 may control the heat pump apparatus 40 to operate so as to be normally operated according to the selected operating course of the clothes care apparatus 1, as in the energy-saving mode.
In the basic mode, the processor 110 may operate in the condensed water heating state, and the at least one flow path, which transmits the refrigerant of the high-temperature state, among the refrigerant pipe 45, may heat the condensed water by passing through the inside of the condensed water collecting apparatus 50. Also, the processor 110 may turn on the power of the forced air current generating apparatus 60. When it is determined that the water level of the collected condensed water is equal to or greater than the first reference water level A and less than the second reference water level B, the processor 110 may control the forced air current generating apparatus 60 to operate. The condensed water equal to or greater than the first reference water level A and less than the second reference water level B may be heated by the at least one flow path operating as the condensed water heating apparatus, and evaporated by the forced air current of the forced air current generating apparatus 60.
According to an embodiment of the disclosure, in response to determining that the collected amount is equal to or greater than the second reference water level B and less than the threshold water level C, the processor 110 may control the clothes care apparatus 1 to the condensed water overload operation. In the condensed water overload operation, the processor 110 may control an operation of the heat pump apparatus 40 according to the selected operating course. The processor 110 may control the heat pump apparatus 40 to operate so as to be normally operated according to the selected operating course of the clothes care apparatus 1, as in the energy-saving mode.
In the condensed water overload operation, the processor 110 may operate in the condensed water heating state, and the at least one flow path, which transmits the refrigerant of the high-temperature state, among the refrigerant pipe 45, may heat the condensed water by passing through the inside of the condensed water collecting apparatus 50. Also, the processor 110 may turn on the power of the forced air current generating apparatus 60. When it is determined that the water level of the collected condensed water is equal to or greater than the second reference water level B and less than the threshold water level C, the processor 110 may control the forced air current generating apparatus 60 to operate.
According to an embodiment of the disclosure, the processor 110 may increase a rotating speed of a fan of the forced air current generating apparatus 60 in the condensed water overload operation, compared to the basic mode. By increasing the rotating speed of the fan, the processor 110 may increase an evaporation speed of the condensed water.
Meanwhile, in the condensed water overload operation, even after a time of the operating course is completed, the processor 110 may turn on the power of the forced air current generating apparatus 60 until the collected amount of the condensed water reaches the second reference water level B. The forced air current generating apparatus 60 may generate the forced air current on the surface of the condensed water so that the collected condensed water is evaporated up to the second reference water level B. When the time of the operating course is completed, the processor 110 no longer operates the heat pump apparatus 40, and thus the at least one flow path may no longer heat the condensed water. Accordingly, the processor 110 may operate in the condensed water heating stopped state.
According to an embodiment of the disclosure, in response to determining that the collected amount is equal to or greater than the threshold water level C, the processor 110 may control the clothes care apparatus 1 to the emergency operation. In the emergency operation, the processor 110 may temporarily stop the operating course of the clothes care apparatus 1 so as to prevent the condensed water stored in the condensed water collecting apparatus 50 from overflowing. When the operating course is proceeded, the condensed water is continuously generated according to the operation of the heat pump apparatus 40, and thus the processor 110 may temporarily stop the operation so as to control the heat pump apparatus 40 not to operate. The processor 110 may evaporate the condensed water through the forced air current generating apparatus 60.
In the emergency operation, the processor 110 may stop the operating course until the collected amount of the condensed water reaches the threshold water level C, and operate the forced air current generating apparatus 60 to accelerate the evaporation of the condensed water. Because the processor 110 does not operate the heat pump apparatus 40, the at least one flow path may not heat the condensed water. Accordingly, the processor 110 may operate in the condensed water heating stopped state.
According to an embodiment of the disclosure, the rotating speed of the fan of the forced air current generating apparatus 60 in the emergency operation may be the same as or greater than that in the condensed water overload operation.
According to an embodiment of the disclosure, the clothes care apparatus 1 may measure the collected amount of the condensed water stored in the condensed water collecting apparatus 50 to adjust the evaporation amount of the condensed water according to situations. When the collected amount of the condensed water is relatively low, the forced air current generating apparatus 60 may not be operated to save energy. When the collected amount of the condensed water is relatively high, the forced air current generating apparatus 60 may be operated even after the operating course is completed or temporarily stopped, so as to increase the evaporation amount of the condensed water.
According to an embodiment of the disclosure, at least one of the energy-saving mode, the basic mode, the condensed water overload operation, or the emergency operation may be omitted. For example, when there is no water level sensor 140 detecting the first reference water level A, the energy-saving mode may be omitted and the processor 110 may perform control according to the basic mode. Also, for example, when there is no water level sensor 140, the processor 110 may operate only in the basic mode. In this case, the condensed water may overflow from the condensed water collecting apparatus 50, and thus caution is required. Also, for example, when there is only the water level sensor 140 detecting the threshold water level C, the processor 110 may operate only in the basic mode and the emergency operation, and the energy-saving mode and the condensed water overload operation may be omitted.

Hereinafter, a control method for the clothes care apparatus 1, according to a value measured by the temperature sensor 120 and the humidity sensor 130, according to an embodiment of the disclosure, will be described with reference to
Referring to
According to an embodiment of the disclosure, the processor 110 may operate in a low-temperature mode when it is determined that the ambient temperature measured by the temperature sensor 120 is less than a first reference temperature X. In the low-temperature mode, the processor 110 may turn on the power of the forced air current generating apparatus 60, regardless of the measured ambient humidity. In the low-temperature mode, the processor 110 operates the heat pump apparatus 40 according to the selected operating course, and thus the at least one flow path transmitting the refrigerant of the high-temperature state may operate as the condensed water heating apparatus. Accordingly, the processor 110 may operate in the condensed water heating state.
According to an embodiment of the disclosure, the processor 110 may control the operation of the forced air current generating apparatus 60, based on the ambient humidity measured by the humidity sensor 130, when the ambient temperature measured by the temperature sensor 120 is relatively high. The processor 110 operates the heat pump apparatus 40 according to the selected operating course, and thus may operate in the condensed water heating state.
For example, the processor 110 may operate in a room-temperature mode when it is determined that the ambient temperature measured by the temperature sensor 120 is equal to or greater than the first reference temperature X. In the room-temperature mode, the processor 110 may control the operation of the forced air current generating apparatus 60, based on the ambient humidity measured by the humidity sensor 130. For example, when the ambient humidity is less than a first reference humidity a, the processor 110 may turn off the power of the forced air current generating apparatus 60. Also, for example, when the ambient humidity is equal to or greater than the first reference humidity a, the processor 110 may turn on the power of the forced air current generating apparatus 60.
Also, for example, the processor 110 may operate in a high-temperature mode when it is determined that the ambient temperature measured by the temperature sensor 120 is equal to or greater than a second reference temperature Y. In the high-temperature mode, the processor 110 may control the operation of the forced air current generating apparatus 60, based on the ambient humidity measured by the humidity sensor 130. For example, when the ambient humidity is less than a second reference humidity 13, the processor 110 may turn off the power of the forced air current generating apparatus 60. Also, for example, when the ambient humidity is equal to or greater than the second reference humidity (3, the processor 110 may turn on the power of the forced air current generating apparatus 60.
In other words, even when the ambient temperature is relatively high, the forced air current generating apparatus 60 may not be operated when humidity is not high, so as to save energy. At this time, the condensed water may be heated and evaporated only through the at least one flow path operating as the condensed water heating apparatus by the heat pump apparatus 40. Also, when the ambient temperature is relatively high and the humidity is high, the forced air current generating apparatus 60 may be operated to increase the evaporation amount of the condensed water. At this time as well, the processor 110 may operate in the condensed water heating state.

The processor 110 may perform the high-temperature mode according to operation S1533. In operation S1531, the processor 110 operates the heat pump apparatus 40 according to the selected operating course, and thus the at least one flow path transmitting the refrigerant of the high-temperature state operates as the condensed water heating apparatus. Accordingly, the processor 110 may operate in the condensed water heating state. Also, in response to determining that the measured ambient temperature is less than the first reference temperature X, the processor 110 may turn off the forced air current generating apparatus 60 in operation S1541.
