Background
Laundry drying appliances (e.g., clothes dryers, clothes washers, etc.) typically include a laundry drum for receiving laundry to be dried and a drying air duct external to and in communication with the laundry drum for blowing a drying air flow through the drying air duct into the laundry drum.

Detailed Description
Fig. 1 is a schematic structural view of a clothes drying apparatus according to one embodiment of the present invention. Referring to fig. 1, the clothes drying apparatus 1 may generally include a cabinet 10 having a laundry taking hole for putting and taking laundry into and out of the cabinet. The laundry taking-in and-out hole is provided with a door body 11 connected to the cabinet 10 to selectively open and/or close the laundry taking-in and-out hole.
Fig. 2 is a schematic structural view of a clothes drying apparatus according to an embodiment of the present invention with a cabinet removed. Referring to fig. 2, the clothes drying apparatus 1 generally further includes a clothes receiving drum disposed in the cabinet 10, a driving device 12, and a drying duct 20. The laundry holding drum may include an outer drum 31 and an inner drum (not shown) for holding laundry to be dried. The driving device 12 is used for controllably driving the inner cylinder to rotate, so that the inner cylinder can be rotatably arranged in the outer cylinder 31. In particular, the driving means 12 may be a driving motor mounted behind the laundry containing drum. The drying duct 20 is used for blowing a drying air flow into the laundry holding drum during the drying process to dry the laundry in the laundry holding drum. In an embodiment of the present invention, the drying air flow may be a low humidity air flow.
In particular, the laundry drying apparatus 1 further comprises a heat exchanging device 50 having a heat absorbing part and a heat radiating part, to which heat of the heat absorbing part of the heat exchanging device 50 can be rapidly transferred. The heat absorbing part is disposed in the drying duct 20 to absorb heat from air in the laundry receiving drum to condense the air. The heat radiating portion is disposed outside the drying duct 20 to radiate heat from the heat absorbing portion. Since a large amount of water vapor is carried by the air flowing out of the clothes containing drum, after the heat absorption part absorbs the heat in the air (including sensible heat of the air and latent heat of the water vapor), the water vapor carried in the air is condensed into liquid water, so that the condensed air becomes relatively dry to enter the clothes containing drum again to dry the clothes. The heat absorbed by the heat absorbing part of the heat exchanging device 50 can be quickly transferred to the heat radiating part and dissipated by the heat radiating part.
In particular, the laundry drying apparatus 1 further comprises liquid cooling means 40 for containing a cooling liquid. The liquid cooling device 40 is disposed outside the drying air duct 20, and is configured to dissipate heat of the heat releasing portion of the heat exchanging device 50 into the cooling liquid contained in the liquid cooling device 40, and discharge the cooling liquid out of the clothes drying apparatus 1. That is, the heat radiating portion of the heat exchanging device 50 can exchange heat with the coolant contained in the liquid cooling device 40, so that the heat of the heat radiating portion is transferred to the coolant and can be discharged out of the drying apparatus along with the coolant. Because the temperature difference between the cooling liquid and the heat release part is larger, the heat of the heat release part is quickly released, so that the heat exchange efficiency of the whole heat exchange device 50 is improved, the high condensation efficiency is realized on the water vapor carried by the damp and hot air discharged from the clothes containing cylinder, the clothes drying time is shortened, and the energy consumption in the clothes drying process is reduced.
In some embodiments of the present invention, the liquid cooling device 40 may be a water cooling device, and the cooling liquid used therein may be cooling water, that is, the cooling water is used to absorb heat of the heat releasing portion of the heat exchanging device 50. The liquid cooling device 40 can introduce cooling water directly through the water inlet of the drying apparatus 1 and discharge the cooling water through the water outlet of the drying apparatus 1. It will be appreciated by those skilled in the art that in other embodiments of the present invention, the liquid cooling device 40 may also absorb heat from the heat radiating portion by using other cooling media, and the source of the cooling media may be a container or the like placed outside the clothes drying apparatus 1.
Fig. 3 is a schematic structural view of a heat exchanging device and a liquid cooling device of a clothes drying apparatus according to one embodiment of the present invention. In order to facilitate observing the position relationship between the heat exchange device and the drying air duct 20, fig. 3 also shows a part of the duct wall of the drying air duct 20. In some embodiments of the present invention, the liquid cooling device 40 may comprise a liquid cooling box 41 having a liquid inlet 411 and a liquid outlet 412, and the cooling liquid may continuously or intermittently enter and exit the liquid cooling box 41 through the liquid inlet 411 and the liquid outlet 412. In order to facilitate the observation of the structure inside the liquid-cooling box 41, a part of the side wall of the liquid-cooling box 41 is omitted in fig. 3. The heat radiating portion of the heat exchanger 50 is provided inside the liquid-cooling tank 41 so as to directly contact the coolant in the liquid-cooling tank 41 and exchange heat. Specifically, the liquid-cooled cartridge 41 has a volume that can contain a volume of cooling liquid therein. For example, the coolant may fill more than two-thirds of the total volume of the liquid-cooled box 41 or almost fill the entire inner cavity of the liquid-cooled box 41, so that the entire heat radiating portion provided inside the liquid-cooled box is in contact with the coolant, thereby maximizing the contact area between the heat radiating portion and the coolant and performing rapid and efficient heat exchange between the two. The liquid inlet 411 may be connected to a water inlet channel of the clothes drying apparatus 1 or an external cooling liquid supply source through a connecting pipe, and the liquid outlet 412 may be connected to a water discharge channel of the clothes drying apparatus 1 or a liquid discharge channel additionally provided to the clothes drying apparatus 1 through a connecting pipe.
Further, the liquid inlet 411 may be disposed at an upper portion of a first sidewall 41a of the liquid-cooling box 41, and the liquid outlet 412 may be disposed at a lower portion of a second sidewall 41b of the liquid-cooling box 41, wherein the first sidewall and the second sidewall are two oppositely disposed sidewalls of the liquid-cooling box 41. Therefore, the external cooling liquid can conveniently flow into the liquid cooling box 41 through the liquid inlet 411, and the cooling liquid can fully contact with the heat release part of the heat exchange device 50 and then flow out of the liquid cooling box 41.
Fig. 4 is a block diagram illustrating a partial module structure of a clothes drying apparatus according to an embodiment of the present invention. In some embodiments of the invention, the laundry drying apparatus 1 further comprises a liquid inlet valve 61 and a liquid outlet valve 62. The inlet valve 61 is configured to allow a controlled flow of external cooling fluid into the cryocassette 41 through the inlet port 411, and the outlet valve 62 is configured to allow a controlled discharge of cooling fluid from the cryocassette 41 through the outlet port 412. That is, the purpose of injecting the coolant into the liquid-cooling box 41 and storing it in the liquid-cooling box 41 or discharging the coolant in the liquid-cooling box 41 out of the clothes drying apparatus can be achieved by controlling the states of the liquid inlet valve 61 and the liquid outlet valve 62. In other words, the clothes drying apparatus 1 according to the embodiment of the present invention may store a certain amount of the coolant in the liquid-cooling box 41, and periodically replace the coolant in the liquid-cooling box 41 through the liquid inlet valve 61 and the liquid outlet valve 62. Therefore, in the clothes drying process of the clothes drying equipment 1, the cooling liquid in the liquid cooling box 41 which does not reach the preset temperature can be continuously utilized, so that the cooling liquid stored in the liquid cooling box 41 can absorb the heat of the heat radiating part of the heat exchange device 50 for a long time.
Specifically. The liquid inlet valve 61 may be disposed in the liquid inlet 411 or the liquid inlet pipeline of the liquid cooling box 41, and the liquid outlet valve 62 may be disposed in the liquid outlet 412 or the liquid outlet pipeline of the liquid cooling box 41.
Further, the clothes drying apparatus 1 further comprises a temperature sensor 63 and a control device 64. The temperature sensor 63 is configured to detect the temperature of the coolant inside the coolant tank 41. The control device 64 is configured to control the open/close state of the liquid inlet valve 61 and/or the liquid outlet valve 62 according to the temperature of the coolant in the liquid-cooling cartridge 41. So that the liquid inlet valve 61 and the liquid outlet valve 62 are kept closed when the temperature of the coolant is lower than the preset temperature to continue to absorb the heat of the heat radiating portion using the coolant. When the temperature of the cooling liquid is higher than the preset temperature, the liquid inlet valve 61 and the liquid outlet valve 62 can be opened simultaneously, or the liquid outlet valve 62 is opened first to discharge the cooling liquid with higher temperature completely, then the liquid inlet valve 61 is opened, and the cooling liquid with lower external temperature is introduced. That is, the coolant in the liquid cooling box 41 can be intermittently discharged, and the coolant can be fully utilized, so that the consumption of the coolant in the clothes drying process of the clothes drying equipment 1 can be reduced as much as possible, and the energy can be saved to the maximum extent. Specifically, the temperature sensor 63 may be installed at an arbitrary position inside the liquid-cooling box 41 which is not in contact with the second heat exchanging fin, and the temperature sensor 63 may be directly in contact with the cooling liquid, thereby detecting the temperature thereof.
In some embodiments of the present invention, the heat exchanging device 50 includes a heat pipe 51 having an evaporation section and a condensation section, a first heat exchanging fin set 52 disposed at the evaporation section, and a second heat exchanging fin set 53 disposed at the condensation section. The evaporation section and the first heat exchanging fin group 52 form a heat absorbing part of the heat exchanging device 50, and the condensation section and the second heat exchanging fin group 53 form a heat emitting part of the heat exchanging device 50. That is, the evaporation section of the heat pipe 51 passes through the wall of the drying air duct 20 and extends into the drying air duct 20, and the first heat exchanging fin set 52 passing through the evaporation section is located in the drying air duct 20. The condensation section of the heat pipe 51 penetrates through the wall surface of the liquid cooling box 41 and extends into the liquid cooling box 41, and the second heat exchange fin group 53 penetrating through the condensation section is positioned in the liquid cooling box 41. The first heat exchanging fin group 52 can enlarge the contact area between the evaporation section of the heat pipe 51 and the air, thereby improving the heat exchanging efficiency of the heat absorbing part of the heat exchanging device 50. The second heat exchanging fin group 53 can enlarge the contact area between the condensation section of the heat pipe 51 and the cooling liquid, thereby improving the heat exchanging efficiency of the heat releasing part of the heat exchanging device 50 and further improving the overall heat exchanging efficiency of the heat exchanging device 50.
Specifically, the heat exchanging device 50 may include a plurality of heat pipes 51, the first heat exchanging fin group 52 may include a plurality of first heat exchanging fins assembled in parallel, through holes are opened at corresponding positions of the plurality of first heat exchanging fins, and evaporation sections of the plurality of heat pipes 51 penetrate through the through holes of the plurality of first heat exchanging fins and are fixedly assembled with the first heat exchanging fins. Similarly, the second heat exchanging fin group 53 may include a plurality of second heat exchanging fins assembled in parallel, through holes are opened at corresponding positions of the plurality of second heat exchanging fins, and the condensing sections of the plurality of heat pipes 51 penetrate through the through holes of the plurality of second heat exchanging fins and are fixedly assembled with the second heat exchanging fins.
The heat pipe is a heat transfer device with high heat transfer efficiency (the heat transfer capacity of the heat pipe is far superior to that of any known metal), and the heat pipe rapidly transfers the heat of the heating body to the outside of the heating body by utilizing the heat conduction principle and the rapid heat transfer property of the phase change medium. In the embodiment of the invention, the heat exchange device in the form of the heat pipe is adopted, so that heat in the hot and humid air in the clothes containing cylinder can be quickly dissipated, and the condensation efficiency of the heat exchange device is further improved.
According to the working characteristics of the heat pipe, the heat pipe can be divided into an evaporation section, a heat insulation section and a condensation section. When the evaporation section of the heat pipe is heated (i.e. when heat is absorbed from the outside), the working medium in the heat pipe is heated and evaporated into steam. The steam flows to the condensation section of the heat pipe under the action of pressure difference, latent heat is released at the condensation section to become condensate, and heat is dissipated through the liquid absorption core and the pipe wall of the condensation section, so that the heat is transferred from high temperature to low temperature. The condensate flows back to the evaporation section under the capillary force of the wick. It should be understood by those skilled in the art that the evaporation section and the condensation section of the heat pipe 51 in the embodiment of the present invention are referred to relative to the state of the working medium inside the heat pipe 51, that is, the section of the heat pipe 51 absorbing heat to evaporate the working medium therein into vapor is the evaporation section, and the section of the gaseous working medium releasing latent heat to become condensate is the condensation section.
Further, the material of the tube body of the heat pipe 51 may be copper, copper alloy, aluminum alloy, stainless steel or other materials, so as to ensure the heat conduction efficiency of the heat exchange device 50.
In some embodiments of the invention, the liquid-cooled cartridge 41 may be generally rectangular parallelepiped, defining a generally rectangular parallelepiped interior space region therein. The plurality of second heat exchange fins of the second heat exchange fin group 53 may be arranged at intervals in the liquid cooling box 41, and the extending direction of each second heat exchange fin is perpendicular to the first side wall 41a and the second side wall 41b of the liquid cooling box 41, on one hand, the coolant in the liquid cooling box 41 can be in uniform contact with the plurality of second heat exchange fins, on the other hand, the resistance of the second heat exchange fins to the coolant can be reduced, and the coolant in the liquid cooling box 41 can flow out through the liquid discharge port 412. Specifically, in the embodiment of the present invention, the first side wall 41a and the second side wall 41b each extend in the vertical direction, and the second heat exchange fins extend in the horizontal direction.
In other embodiments of the present invention, the liquid cooling box 41 may also be a hollow box body with an oblate, oval or other cross section, and the first side wall 41a and the second side wall 41b may be curved surfaces, in which case the second heat exchanging fins may also extend in the horizontal direction.
In some embodiments of the present invention, referring to fig. 2 and 3, drying duct 20 has a supply air outlet 21 for supplying a high-temperature and low-humidity drying air flow into the laundry drum and a return air outlet 22 for receiving a high-temperature and high-humidity air flow from the laundry drum. The heat absorbing part of the heat exchanging device 50 is disposed in a section of the drying duct 20 adjacent to the return air inlet 22 thereof so as to exchange heat with the heat absorbing part when the high temperature and high humidity gas just flows out of the laundry-accommodating drum. The first heat exchanging fins of the first heat exchanging fin set 52 are arranged at intervals, and the extending direction of each of the first heat exchanging fins is parallel to the air flowing direction in the section of the drying air duct 20 adjacent to the air return opening 22 thereof. Specifically, the plurality of first heat exchange fins of the first heat exchange fin group 52 extend in the horizontal plane, and the air in the section of the drying air duct 20 adjacent to the air return opening 22 flows along the horizontal direction through the gaps between the plurality of first heat exchange fins, so that on one hand, the uniformity of the contact between the air and the first heat exchange fins can be ensured, on the other hand, the air flow resistance in the drying air duct 20 is reduced, and the noise of the clothes drying device 1 in the clothes drying process is reduced to a certain extent.
Further, the liquid cooling device 40 can be disposed above the section of the drying air duct 20 adjacent to the air return opening 22 thereof, so as to avoid occupying other space in the casing 10, and make the structure of the clothes drying apparatus 1 more compact.
In some embodiments of the present invention, the supply opening 21 of the drying duct 20 may be located at an upper side of the front of the tub 31, and the return opening 22 of the drying duct 20 may be located at a lower side of the rear of the tub 31, the upper side of the front of the tub 31 and the lower side of the rear of the tub 31 being diagonally opposite to each other. That is, the supply port 21 and the return port 22 may be located approximately at two corner positions of a diagonal line of an axial section of the outer tube 31 through its central axis. Therefore, the hot air entering the clothes containing barrel from the air supply opening 21 can flow through the longest path in the clothes containing barrel as much as possible, so that the contact time of the hot air and the clothes to be dried in the clothes containing barrel is prolonged, the clothes drying effect is improved, and the clothes drying time is shortened. Specifically, the air supply opening 21 may be located at the upper side of the neck of the outer tube 31, and the air return opening 22 may be located at the lower side of the bottom of the outer tube 31 and near the edge of the bottom of the outer tube 31. In other embodiments of the present invention, the air supply opening 21 and the air return opening 22 may be located at other positions diagonally opposite to the outer cylinder 31 in order to facilitate installation of the drying duct 20 and other structures in the cabinet 10.
In order to circulate the air between the laundry drum and the drying air duct 20 quickly and efficiently, in some embodiments of the invention, the laundry drying apparatus 1 further comprises a circulation fan 70. The circulating fan 70 is disposed in the drying duct 20 and located downstream of the heat absorbing portion of the heat exchanging device 50. The circulating fan 70 is used for driving drying air flow to circulate between the drying air duct 20 and the clothes containing drum, so as to accelerate the clothes drying process of the clothes drying device 1.
In some embodiments of the present invention, in order to make the drying air flow evaporate the moisture in the laundry more effectively, the clothes drying apparatus 1 further comprises a heating device 80. The heating device 80 is disposed in the drying air duct 20 and located downstream of the heat absorbing portion of the heat exchanging device 50, and is configured to heat the air flowing through the heating device, so that the air forms hot air with a temperature higher than the ambient temperature. That is, the heating device 80 may increase the temperature of the drying air flow entering the laundry drum. The heating device 80 is located at the downstream of the heat absorption part of the heat exchange device 50 in the drying air duct 20, that is, the heat exchange device 50 condenses the air flow from the clothes containing cylinder, and then the heating device 80 heats the condensed air flow, so that the moisture in the air flow from the clothes containing cylinder is prevented from being evaporated again in the heating process and entering the clothes containing cylinder to affect the clothes drying effect.
Further, the heating device 80 may be connected to the control device 64 to intermittently initiate the heating operation under the control of the control device 64. For example, when the temperature of the drying airflow fed into the clothes holding drum is higher than the first preset temperature, the heating device 80 may be stopped to prevent the drying airflow from being damaged by the over-high temperature. When the temperature of the drying air flow fed into the laundry drum is lower than the second preset temperature, the device 80 may be heated to continue the heating operation of the air flowing therethrough. In some embodiments of the present invention, the first predetermined temperature may be 130 ℃ for example, and the second predetermined temperature may be 90 ℃ for example.
In some embodiments of the present invention, the drying duct 20 may include an upstream section 20a provided with a heat absorbing portion of the heat exchanging device 50, a downstream section 20c provided with the circulation fan 70 and the heating device 80, and an intermediate section 20b between the upstream section 20a and the downstream section 20 c. The upstream section 20a communicates directly with the return air opening 22, and the downstream section 20c communicates directly with the supply air opening 21. The downstream section 20c extends parallel to the central axis direction of the laundry drum, and at least part of the intermediate section 20b is perpendicular to the downstream section 20 c. Therefore, the drying air duct 20 can be prevented from turning at a large angle, and the drying air flow can flow rapidly in the drying air duct 20.
Specifically, the downstream section 20c of drying duct 20 may be located above the side of the laundry drum and extend in a substantially horizontal direction. The circulator blower 70 is located at the forward end of the downstream section 20c adjacent the intermediate section 20b, and the heating device 80 is located downstream of the circulator blower 70. Downstream section 20c of drying duct 20 may be generally flat tubular, and heating device 80 may be an S-shaped tubular heater secured within downstream section 20 c. The middle section 20b and the downstream section 20c of the drying duct 20 may constitute a substantially L-shaped duct, at least a portion of the middle section 20b may extend downward perpendicular to the downstream section 20c, and the upstream section 20a may extend in a horizontal plane perpendicular to the central axis of the laundry receiving drum.
Fig. 5 is a schematic flow chart of a drying method of a drying apparatus according to an embodiment of the present invention. The clothes drying method of the clothes drying equipment 1 in the embodiment of the invention comprises the following steps:
supplying a drying air flow into a laundry drum of the laundry drying apparatus 1 to dry the laundry in the laundry drum with the drying air flow;
the heat absorption part of the heat exchange device 50 of the clothes drying equipment 1 is utilized to absorb the heat in the air from the clothes containing cylinder so as to condense the heat;
dissipating the heat of the heat radiating part of the heat exchanging device 50 to the cooling liquid contained in the liquid cooling device 40 by using the liquid cooling device 40 of the clothes drying equipment 1; and
the cooling liquid carrying the heat of the heat radiating part is discharged out of the clothes drying apparatus 1.
In the process of drying the laundry using the hot air, the air in the laundry container may sequentially pass through a portion of the heat exchanging device 50 and the heating device 80 in the drying duct 20, and then return to the inside of the laundry container to be continuously circulated.
Fig. 6 is a schematic flow chart of a drying method of a drying apparatus according to another embodiment of the present invention. Referring to fig. 5 and 6, the step of discharging the coolant carrying the heat of the heat radiating part out of the clothes drying apparatus 1 includes:
detecting the temperature of the cooling liquid in the liquid cooling device 40; and
when the measured temperature of the cooling liquid is higher than the preset temperature, the cooling liquid in the liquid cooling device 40 is discharged to the outside of the drying apparatus 1, and the cooling liquid having a temperature lower than the preset temperature is replenished to the liquid cooling device 40.
When the temperature of the cooling liquid is lower than the preset temperature, the temperature of the cooling liquid is lower than that of the air flowing out of the clothes containing drum, and the cooling liquid has higher heat absorption potential, so that the heat of the heat radiating part can be continuously absorbed. When the temperature of the cooling liquid is lower than the preset temperature, the potential of the cooling liquid for absorbing heat is reduced, which indirectly affects the heat exchange efficiency of the heat exchange device 50, and further affects the condensation efficiency of condensing the water vapor contained in the air flowing out of the clothes containing cylinder. Specifically, the preset temperature may range from 40 ℃ to 55 ℃.
According to an embodiment of the laundry drying apparatus 1 of the present invention, the temperature of the cooling liquid inside the liquid-cooling box 41 can be detected by the temperature sensor 63. The open and close states of the liquid inlet valve 61 and/or the liquid outlet valve 62 are controlled by the control device 64, so that the cooling liquid in the liquid cooling device 40 is discharged to the outside of the drying apparatus 1, and the cooling liquid with the temperature lower than the preset temperature is replenished to the liquid cooling device 40.
Further, the drying method of the drying apparatus 1 further includes:

status parameters of the level switch located in the liquid cooling box 41 of the liquid cooling device 40.
That is, in order to be able to accurately control the amount of cooling liquid in the liquid-cooled box 41, the laundry drying apparatus 1 further comprises a flow sensor located in the inlet flow path of the liquid cooling device 40 and/or a level switch located in the liquid-cooled box 41.
When the liquid-cooling box 41 is replenished with the cooling liquid, the liquid-cooling box 41 can be replenished with the cooling liquid at a constant flow rate by controlling the liquid inlet valve 61, and then the replenishment time of the cooling liquid is controlled by the control device 64, so that the amount of the cooling liquid replenished in the liquid-cooling box 41 can be determined.
The flow sensor may sense the flow rate of the cooling fluid flowing therethrough, thereby directly determining the amount of cooling fluid replenished in the liquid-cooled cartridge 41 by the flow rate of the cooling fluid flowing through the inlet flow path.
The level switch may be provided at a fixed position in the liquid-cooled cartridge 41 so that it can be determined that the amount of cooling liquid in the liquid-cooled cartridge 41 reaches a fixed threshold when the cooling liquid rises to the fixed position.
