Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a clothing processing device. Background Art

[0002] Clothes processing devices such as dryers and washer-dryers are household appliances that use electricity to generate heat to dry clothes. As consumers' living standards improve, their requirements for clothing processing devices are also getting higher and higher.

[0003] A clothing processing device typically comprises a housing, a drum assembly, and a drying duct. The drum assembly is located within the housing and comprises an outer drum and an inner drum, with the inner drum forming a clothing processing chamber. The drying duct is located on the outer wall of the outer drum, with both ends of the drying duct communicating with the clothing processing chamber. A heater is installed within the drying duct to create a dry airflow circulation within the drying duct, outer drum, and inner drum, drying the clothes within the clothing processing chamber.

[0004] Current laundry processing devices typically only have a water inlet located at the top of the outer drum's rear wall, providing condensed water to the rear wall to cool it and condense the air flowing through it. However, this approach suffers from low condensation efficiency and uneven condensation, which can lead to low drying efficiency. Utility Model Content

[0005] The purpose of the present utility model is to provide a clothes processing device to optimize the condensation structure on the rear wall of the outer drum in the clothes processing device and improve the condensation efficiency.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] According to one aspect of the present invention, the present invention provides a clothes processing device, comprising:

[0008] a housing forming an outer shell of the laundry treating device;

[0009] An outer cylinder is provided in the box body, and a return air port is provided on the rear wall of the outer cylinder;

[0010] an inner drum rotatably disposed in the outer drum, wherein a clothes processing chamber is formed in the inner drum;

[0011] a drying duct assembly, disposed outside the outer drum, for providing drying airflow into the clothing processing chamber; a drying duct assembly is formed with one end of the drying duct communicating with the return air port and the other end communicating with the clothing processing chamber, so that airflow circulates through the drying duct, the clothing processing chamber, and the return air port;

[0012] A condensation pan is provided on the rear wall inside the outer cylinder, with an overflow gap space formed between the condensation pan and the rear wall of the outer cylinder, and the airflow circulates through the condensation pan;

[0013] a top water inlet, provided on the rear wall of the outer cylinder; the top water inlet is provided in the top area of ​​the back side of the condensation pan, the top water inlet is communicated with the flow gap space, so that the condensed water provided by the top water inlet flows into the flow gap space;

[0014] a first water inlet, provided on the rear wall of the outer cylinder and on the back side of the condensation pan; the first water inlet is in communication with the flow gap space, so that condensed water provided by the first water inlet flows into the flow gap space;

[0015] Wherein, a straight line passing through the axis of the condensation tray along the height direction of the clothes processing device is a first reference line, and a plane passing through the first reference line along the depth direction of the clothes processing device is a first reference plane;

[0016] A straight line passing through the axis of the condensation tray along the width direction of the laundry processing device is a second reference line, and a plane passing through the second reference line along the depth direction of the laundry processing device is a second reference plane;

[0017] The first water inlet and the return air outlet are respectively arranged on opposite sides of the first reference surface, and the first water inlet and the return air outlet are arranged above the second reference surface;

[0018] The top water inlet and the first water inlet are configured to respectively provide condensed water to the flow gap spaces in different areas on the back side of the condensation pan.

[0019] The above technical solution has the following advantages or beneficial effects: by forming a flow gap space between the rear wall of the condensation pan and the rear wall inside the outer cylinder, external condensed water can flow into the flow gap space. In this way, the condensed water entering the flow gap space can achieve surface contact heat exchange with the condensation pan, cooling the condensation pan and improving the cooling efficiency of the condensation pan. This allows the condensation pan to maintain a low temperature and continuously exchange heat with the hot and humid air, thereby enabling the condensation pan to continuously condense and dehumidify the hot and humid air, thereby improving the condensation efficiency of the hot and humid air.

[0020] By providing condensed water to the flow gap space in the area below it through the top water inlet, most areas of the condensation tray can be condensed. By providing condensed water to the flow gap space in the area below it through the first water inlet, the condensation tray can be partially condensed, which is beneficial to increase the contact area between the condensed water and the condensation tray, thereby improving the cooling effect of the condensation tray and avoiding waste of water resources.

[0021] In addition, during the clothes drying process, the top water inlet and the first water inlet can be controlled separately to determine whether to provide condensation water to the flow gap space. For example, the top water inlet and the first water inlet provide condensation water at the same time, the top water inlet continuously provides condensation water in conjunction with the first water inlet intermittently providing condensation water, or the top water inlet provides condensation water alone, or the top water inlet and the first water inlet stop providing condensation water at the same time, thereby intelligently adjusting the condensation efficiency of the condensation water on the condensation tray, intelligently adjusting and controlling the temperature of the condensation tray to keep the condensation tray at a low temperature, and achieving the effect of saving water and improving efficiency.

[0022] In some embodiments of the present application, a water channel is formed between the condensation pan and the rear wall of the outer cylinder, and the water channel is connected to the flow gap space; the top water inlet is connected to the water channel, and the condensed water provided by the top water inlet can flow into the water channel and flow to the flow gap space below it through the water channel; the first water inlet is connected to the water channel, and the condensed water provided by the first water inlet can flow into the water channel and flow to the flow gap space below it through the water channel.

[0023] The above technical solution has the following advantages or beneficial effects: the flow gap space is connected through the water channel, and the top water inlet is connected to the water channel, and the first water inlet is connected to the water channel, so that the condensed water provided by the top water inlet and the first water inlet can flow quickly along the water channel to different areas of the condensation tray and the flow gap space, which can increase the dispersion speed of the condensed water and the speed at which the condensed water enters the flow gap space, which is conducive to saving water resources and avoiding waste of water resources.

[0024] In some embodiments of the present application, the water channel is recessed and formed on the back side of the condensation tray; and condensation ribs arranged corresponding to the water channel are formed on the front wall of the condensation tray.

[0029] The above-mentioned technical solution has the following advantages or beneficial effects: multiple first water channels are connected through the second water channel, so that the water inlet can be connected only to the first water channel or only to the second water channel, so that the condensed water can flow in the first water channel and the second water channel respectively, which can increase the dispersion speed of the condensed water in the first water channel and the second water channel, and thus increase the speed at which the condensed water enters the flow gap space.

[0030] In some embodiments of the present application, the bottom edge of the flow gap space is connected to the inner space of the outer tube; the condensed water in the flow gap space can flow into the inner space of the outer tube through the bottom edge thereof.

[0031] The above technical solution has the following advantages or beneficial effects: when the water inlet provides condensed water into the flow-through gap space, the condensed water can flow downward along the flow-through gap space, flow through the bottom edge of the flow-through gap space into the interior space of the outer tube, and can be discharged through the bottom area of ​​the outer tube. In addition, the condensed water in the flow-through gap space flows through its bottom edge into the interior space of the outer tube, allowing the condensed water provided by the water inlet to smoothly enter the flow-through gap space.

[0032] In some embodiments of the present application, in the front-to-back direction of the outer cylinder, the width of the flow gap space ranges from 0.1 mm to 0.3 mm.

[0033] The above technical solution has the following advantages or beneficial effects: through the structural design of the width of the flow gap space ranging from 0.1mm to 0.3mm, the condensed water can not only smoothly enter the flow gap space, ensuring the flow rate of the condensed water in the flow gap space; but also a small amount of condensed water can be distributed in a larger area of ​​the flow gap space, thereby increasing the contact area between the condensed water and the condensation plate.

[0034] In some embodiments of the present application, an angle between a line connecting the first water inlet and the axis of the condensation tray and the first reference line is between 20° and 45°.

[0035] The above technical solution has the following advantages or beneficial effects: by setting the angle between the line connecting the first water inlet and the axis of the condensation tray and the first reference line in the range of 20° to 45°, it is possible to maintain a sufficient distance between the top water inlet and the first water inlet, and to maintain a sufficient height of the first water inlet, so that the first water inlet is located as much as possible in the top area of ​​the back side of the condensation tray, which is beneficial to increase the contact area and contact area between the condensed water provided by the top water inlet and the first water inlet and the back side of the condensation tray, and is beneficial to make the temperature distribution of the condensation tray uniform.

[0039] The above technical solution has the following advantages or beneficial effects: by utilizing the temperature sensor to contact the back of the condensation tray, the temperature of the condensation tray can be detected and monitored in real time.

[0040] In some embodiments of the present application, the condensation plate includes a shielding portion, which is arranged at the return air outlet and covers at least a portion of the return air outlet; a plurality of ventilation holes are provided on the shielding portion, and the ventilation holes connect the return air outlet and the internal space of the outer cylinder.

[0041] The above technical solution has the following advantages or beneficial effects: Through the structural design of the shielding portion and the ventilation holes, during the clothes drying process, air inside the outer drum can enter the return air port through the ventilation holes of the shielding portion and then enter the drying air duct, thereby improving air circulation efficiency. When air flows through the ventilation holes of the shielding portion, the shielding portion can also condense and dehumidify the air passing through it.

[0042] According to another aspect of the present invention, the present invention provides a clothes processing device, comprising:

[0043] a housing forming an outer shell of the laundry treating device;

[0044] An outer cylinder is provided in the box body, and a return air port is provided on the rear wall of the outer cylinder;

[0046] a drying duct assembly, disposed outside the outer drum, for providing drying airflow into the clothing processing chamber; a drying duct assembly is formed with one end of the drying duct communicating with the return air port and the other end communicating with the clothing processing chamber, so that airflow circulates through the drying duct, the clothing processing chamber, and the return air port;

[0047] A condensation pan is provided on the rear wall inside the outer cylinder, with an overflow gap space formed between the condensation pan and the rear wall of the outer cylinder, and the airflow circulates through the condensation pan;

[0053] The top water inlet, the first water inlet, and the second water inlet are configured to respectively provide condensed water to the overflow gap spaces in different areas on the back side of the condensation pan.

[0054] The above technical solution has the following advantages or beneficial effects: by forming a flow gap space between the rear wall of the condensation pan and the rear wall inside the outer cylinder, external condensed water can flow into the flow gap space. In this way, the condensed water entering the flow gap space can achieve surface contact heat exchange with the condensation pan, cooling the condensation pan and improving the cooling efficiency of the condensation pan. This allows the condensation pan to maintain a low temperature and continuously exchange heat with the hot and humid air, thereby enabling the condensation pan to continuously condense and dehumidify the hot and humid air, thereby improving the condensation efficiency of the hot and humid air.

[0055] By providing condensed water to the flow gap space in the area below it through the top water inlet, most areas of the condensation tray can be condensed.

[0092] Figure 1 This is a structural diagram of a clothing processing device according to some embodiments of the present invention.

[0093] like Figure 1 As shown, the laundry treatment device provided in an embodiment of the present invention may include a housing 1. The housing 1 may be configured as an external housing for the laundry treatment device. The housing 1 may typically have a hollow rectangular structure. It should be noted that in other embodiments, the external shape of the housing 1 may be designed as desired and is not limited herein. The interior of the housing 1 may be used to provide installation space.

[0094] In some embodiments, a clothing inlet (not shown) may be provided on the front side wall of the box 1. The clothing inlet may be connected to the interior space of the box 1. Clothes may be placed into the box 1 through the clothing inlet for washing.

[0095] See also Figures 1 to 2As shown, in some embodiments, a door cover 11 may be provided on the front side wall of the box body 1. The door cover 11 can be used to open and close the clothing input port on the front side wall of the box body 1, and then the space inside the box body 1 can be opened and closed through the door cover 11.

[0096] In some embodiments, the door cover 11 can be connected to the box body 1 through a hinge, and the door cover 11 can rotate around the axis of the hinge to open and close the door cover 11 and open and close the clothing input port.

[0097] Figure 2 It is a structural diagram of the drum assembly 2 and the drying air duct assembly 3 of some embodiments of the present invention.

[0098] like Figures 1 to 2 As shown, the clothing processing device may include a drum assembly 2. The drum assembly 2 may be arranged in the housing 1. The drum assembly 2 may extend along the front-to-back direction of the housing 1. A clothing processing chamber 20 may be formed in the drum assembly 2. A barrel opening may be formed on the front end surface of the drum assembly 2. The barrel opening is connected to the inside of the clothing processing chamber 20. The barrel opening is opposite to the clothing input port of the housing 1 and the door cover 11. After the door cover 11 is opened, clothing can be sequentially placed into the clothing processing chamber 20 in the drum assembly 2 through the clothing input port on the front side of the housing 1 and the barrel opening at the front end of the drum assembly 2 to perform operations such as clothing washing and clothing dehydration. When the housing 1 is closed, the housing 1 can simultaneously close the clothing input port and the clothing processing chamber 20.

[0099] In some embodiments, the drum assembly 2 may include an outer drum 21. The outer drum 21 may be disposed inside the housing 1. The outer drum 21 may be configured as a tub for holding wash water. The interior space of the outer drum 21 may be used to hold wash liquid, such as water, detergent, softener, and the like.

[0100] In some embodiments, the drum assembly 2 may include an inner drum 22. The inner drum 22 may be arranged inside the outer drum 21. The clothing processing chamber 20 may be formed inside the inner drum 22. The clothing processing chamber 20 in the inner drum 22 is used to hold the clothes to be washed. A water hole (not shown in the figure) may be provided on the peripheral wall of the inner drum 22. The clothing processing chamber 20 may be connected to the space between the inner drum 22 and the outer drum 21 through the water hole. The washing liquid in the outer drum 21 can enter the clothing processing chamber 20 in the inner drum 22 through the water hole, that is, the washing liquid in the space between the inner drum 22 and the outer drum 21 can enter the clothing processing chamber 20 in the inner drum 22 through the water hole.

[0101] In some embodiments, the inner drum 22 can be rotatably disposed within the outer drum 21. When the inner drum 22 rotates relative to the outer drum 21, the inner drum 22 can drive the clothes to rotate relative to the outer drum 21, thereby achieving a washing function for the clothes within the clothes processing chamber 20 in the inner drum 22 and improving the uniformity of washing and dehydrating the clothes.

[0102] It should be noted that, in other embodiments, the clothing processing chamber 20 can also be used for drying clothing, such as a clothes dryer or a washer-dryer.

[0103] In some embodiments, the outer cylinder 21 and the inner cylinder 22 may also be coaxially arranged inside and outside. The front ends of the outer cylinder 21 and the front ends of the inner cylinder 22 may be provided with openings arranged opposite to each other. The front end openings of the outer cylinder 21 and the front end openings of the inner cylinder 22 may be combined to form the cylinder mouth of the cylinder assembly 2.

[0104] like Figure 2 As shown, in some embodiments, a drive device (not shown), such as a drive motor, may be provided within the housing 1. The drive device may be located outside the outer drum 21. The drive device may also be located within the housing 1. The output end of the drive device is in transmission connection with the inner drum 22. When the drive device is able to drive the inner drum 22 to rotate relative to the outer drum 21, the laundry processing chamber 20 in the inner drum 22 can be washed or dehydrated.

[0105] It should be noted that, in some other embodiments, the output end of the driving device may also be connected to the inner cylinder 22 through a transmission device.

[0106] In some embodiments, the drum assembly 2 may include a door seal 23. The door seal 23 may be located at the front end of the drum assembly 2. The door seal 23 may be annular in shape. The door seal 23 may be located between the clothing inlet and the opening of the drum assembly 2. The door seal 23 may be used to seal the gap between the clothing inlet of the housing 1 and the opening of the drum assembly 2. In this way, the door seal 23 may prevent wash water in the drum assembly 2 from entering the interior of the housing 1.

[0107] In some embodiments, the door seal 23 can be made of an elastic sealing material. The door seal 23 has an annular structure and is arranged around the circumference of the clothing inlet and the circumference of the barrel opening of the drum assembly 2. The circumferential edge of the front end of the door seal 23 is sealed with the circumferential edge of the clothing inlet of the housing 1, and the circumferential edge of the rear end of the door seal 23 is sealed with the circumferential edge of the barrel opening of the outer barrel 21, thereby sealing the gap between the clothing inlet of the housing 1 and the barrel opening of the outer barrel 21. In this way, when the cabinet door closes the clothing inlet on the front side of the housing 1, the door seal 23 can prevent water in the clothing treatment chamber 20 from entering the housing 1, and at the same time, the cabinet door can prevent water in the clothing treatment chamber 20 from overflowing from the clothing inlet of the housing 1.

[0109] like Figure 2 and Figure 3As shown, in some embodiments, the laundry processing device may include a drying duct assembly 3. The drying duct assembly 3 may be disposed within the housing 1. The drying duct assembly 3 may be disposed outside the drum assembly 2. A drying duct (not shown) may be disposed within the drying duct assembly 3. The drying duct is configured to provide a drying airflow into the laundry processing chamber 20, thereby drying the laundry in the laundry processing chamber 20 and achieving a laundry drying function.

[0110] like Figure 3 As shown, in some embodiments, an air inlet 24 may be provided on the outer wall of the drum assembly 2. The air inlet 24 may be located at the door seal 23. The air inlet 24 may communicate with the opening of the inner drum 22, thereby connecting the air inlet 24 to the laundry processing chamber 20 within the inner drum 22. One end of the drying duct may communicate with the air inlet 24. In this way, the drying airflow within the drying duct may enter the laundry processing chamber 20 through the air inlet 24, drying the laundry within the laundry processing chamber 20.

[0111] It should be noted that, in some other embodiments, the air inlet 24 may also be provided at other positions on the outer wall of the cylinder assembly 2 , such as other positions on the outer wall of the outer cylinder 21 .

[0112] In some embodiments, a return air vent 25 may be provided on the outer wall of the drum assembly 2. The return air vent 25 may be provided on the rear wall of the outer drum 21. The return air vent 25 may pass through the interior space of the outer drum 21, thereby connecting the return air vent 25 to the laundry processing chamber 20 within the inner drum 22. The other end of the drying air duct may be connected to the return air hole 43 of the return air vent 25.

[0113] In this way, when the drying duct provides drying airflow to the laundry processing chamber 20 through the air inlet 24, the air in the laundry processing chamber 20 can enter the outer drum 21 and return to the drying duct through the return air outlet 25, thereby achieving a circulation of drying airflow in the drying duct and the laundry processing chamber 20. In this way, the airflow can circulate in the drying duct, the air inlet 24, the laundry processing chamber 20, and the return air outlet 25, achieving a circulation of air between the drying duct and the laundry processing chamber 20.

[0114] It should be noted that, in some other embodiments, the return air port 25 may also be provided at other positions on the outer wall of the cylinder assembly 2 , such as other positions on the outer wall of the outer cylinder 21 .

[0115] like Figure 2 and Figure 3As shown, in some embodiments, the drying duct assembly 3 may include a fan 31. The fan 31 may be provided in the drying duct. The fan 31 is configured to provide wind force for the circulation of the drying air flow. The fan 31 may be provided at one end of the drying duct close to the return air port 25. The suction side of the fan 31 may be set in the direction of the return air port 25. The outlet side of the fan 31 may be set in the direction of the air inlet 24. In this way, when the fan 31 is running, the suction side of the fan 31 may form a negative pressure suction force, and then the air inside the outer drum 21 and the clothing processing chamber 20 may be extracted through the return air port 25. The extracted air enters the drying duct and is then transported to the clothing processing chamber 20 through the air inlet 24.

[0116] It should be noted that, in some other embodiments, the fan 31 may also be arranged at other positions of the drying air duct.

[0117] like Figure 2 and Figure 3 As shown, in some embodiments, the drying duct assembly 3 may include a heating element 32. The heating element 32 may be provided in the drying duct. The heating element 32 may be a heating device such as a heating tube. The heating element 32 may heat the air in the drying duct. The heating element 32 may generate a high-temperature drying airflow in the drying duct. In this way, when the heating element 32 is heating, the wind force of the fan 31 may blow the drying airflow in the drying duct through the air inlet 24 into the clothing processing chamber 20, thereby realizing the clothing drying function in the clothing processing chamber 20.

[0118] In some embodiments, the end of the heating element 32 can be exposed to the outer wall of the drying duct assembly 3. In this way, the end of the heating element 32 can be connected to the power supply through a wire, and then the heating element 32 can be powered by the power supply.

[0119] In some embodiments, the heating element 32 can be located at one end of the drying duct near the air inlet 24. The heating element 32 can also be located on the side of the fan 31 near the air inlet 24. The heating element 32 can also be located on the outlet side of the fan 31. In this way, the fan 31 can draw air from the laundry processing chamber 20 into the drying duct through the return air vent 25. The heating element 32 then heats the air entering the drying duct, and the resulting dry airflow is then fed into the laundry processing chamber 20 through the air inlet 24.

[0120] It should be noted that, in some other embodiments, the heating element 32 may also be arranged at other positions of the drying air duct.

[0121] Figure 4 2 is a structural diagram of the outer cylinder 21 of some embodiments of the present invention. Figure 5 yes Figure 4 A decomposition diagram of .

[0122] like Figure 4 and Figure 5 As shown, in some embodiments, the laundry processing device may include a condensation tray 4. The condensation tray 4 may be located on the rear wall of the outer tub 21. The condensation tray 4 can be used to condense air flowing through the condensation tray 4. During the laundry drying process, the dry airflow contacts the wet laundry in the laundry processing chamber 20, generating a large amount of hot and humid air. When the hot and humid air in the laundry processing chamber 20 enters the outer tub 21 and flows into the drying duct through the return air vent 25, the hot and humid air can flow over the surface of the condensation tray 4, pre-cooling the hot and humid air. Simultaneously, moisture in the hot and humid air can condense on the surface of the condensation tray 4, flowing down along the surface of the condensation tray 4 to the bottom area of ​​the outer tub 21 and then discharged through the drain port. In this way, the condensation tray 4 can condense and cool the hot and humid air in the laundry processing chamber 20, removing moisture from the air. This allows the dry air with less moisture to be reheated into the drying duct, where it is reheated to a high-temperature dry airflow. This is then re-delivered into the laundry processing chamber 20 through the air inlet 24 to dry the laundry, thereby improving drying efficiency.

[0123] like Figure 4 and Figure 5 As shown, in some embodiments, a bearing seat 211 may be provided at the center of the rear wall of the outer cylinder 21. A transmission shaft (not shown) may be provided within the bearing seat 211. The transmission shaft may be rotatably disposed within the bearing seat 211. The outer end of the transmission shaft may be in driving connection with a drive device. The inner end of the transmission shaft may be connected to the rear wall of the inner cylinder 22. In this manner, the drive device may drive the inner cylinder 22 to rotate via the transmission shaft, causing the inner cylinder 22 to rotate relative to the outer cylinder 21.

[0124] like Figure 4 and Figure 5 As shown, in some embodiments, the condensation pan 4 may be an annular structure, such as a circular ring structure, and the condensation pan 4 may be arranged around the circumference of the bearing seat 211 .

[0125] like Figure 5 As shown, in some embodiments, the condensation pan 4 can be detachably fixed to the rear wall inside the outer cylinder 21. A first fixing hole 212 can be provided on the rear wall inside the outer cylinder 21. The first fixing hole 212 can be a countersunk hole. A second fixing hole 41 can be provided on the condensation pan 4. The second fixing hole 41 can be a through hole extending forward and backward, and the second fixing hole 41 can pass through the condensation pan 4 forward and backward. The second fixing hole 41 can be arranged corresponding to the first fixing hole 212. In this way, a screw can be inserted into the second fixing hole 41 of the condensation pan 4, and the screw can be fixed in the first fixing hole 212, thereby detachably fixing the condensation pan 4 to the rear wall inside the outer cylinder 21.

[0126] In some embodiments, a plurality of first fixing holes 212 may be provided on the rear wall inside the outer cylinder 21. The plurality of first fixing holes 212 may be arranged at intervals. A plurality of second fixing holes 41 may be provided on the condensation pan 4. The plurality of second fixing holes 41 are arranged corresponding to the plurality of first fixing holes 212. In this way, by using a plurality of screws in conjunction with the plurality of first fixing holes 212 and the plurality of second fixing holes 41, the condensation pan 4 can be stably fixed to the rear wall inside the outer cylinder 21, preventing the condensation pan 4 from moving, thereby improving the stability and firmness of the installation of the condensation pan 4. In addition, the number and position of the first fixing holes 212 and the second fixing holes 41 can be adjusted as needed and are not limited here.

[0127] It should be noted that, in some other embodiments, the condensation pan 4 can also be welded and fixed on the rear wall inside the outer cylinder 21. Alternatively, the condensation pan 4 can also be integrally formed on the rear wall inside the outer cylinder 21.

[0128] like Figure 4 and Figure 5 As shown, in some embodiments, the condensation pan 4 can be made of metal. In this way, the condensation pan 4 made of metal has good thermal conductivity and can improve the condensation efficiency of hot and humid air.

[0129] In some embodiments, the outer cylinder 21 can be made of plastic and can be formed by injection molding. The outer cylinder 21 formed by injection molding can reduce costs.

[0130] It should be noted that, in some other embodiments, the outer cylinder 21 may also be made of metal, so that the inner wall of the outer cylinder 21 can also condense and cool the hot and humid air inside it.

[0131] Figure 6 yes Figure 4 A front view of . Figure 7 yes Figure 6 The structural diagram in which the condensation tray 4 is removed.

[0132] like Figure 6 and Figure 7 As shown, in some embodiments, the condensation tray 4 may include a shielding portion 42. The return air outlet 25 may be recessed on the rear wall inside the outer cylinder 21. When the condensation tray 4 is installed on the rear wall inside the outer cylinder 21, the shielding portion 42 may be provided at the return air outlet 25, and the shielding portion 42 may cover at least a portion of the return air outlet 25. The area not covered by the shielding portion 42 may form a return air hole 43. The return air hole 43 may connect the internal space of the outer cylinder 21 and the return air outlet 25. In this way, the air inside the outer cylinder 21 may enter the return air outlet 25 through the return air hole 43, and then enter the interior of the drying air duct. When the air flows through the shielding portion 42, the shielding portion 42 may also condense and dehumidify the air flowing through.

[0133] In some embodiments, a plurality of ventilation holes 421 may be provided on the shielding portion 42. The ventilation holes 421 connect the return air port 25 and the internal space of the outer cylinder 21. The plurality of ventilation holes 421 may be arranged at intervals. In this way, the air inside the outer cylinder 21 can enter the return air port 25 through the ventilation holes 421 of the shielding portion 42, and then enter the drying air duct, thereby improving the air circulation efficiency. When the air flows through the ventilation holes 421 of the shielding portion 42, the shielding portion 42 can also condense and dehumidify the air flowing through. In addition, the size, shape and number of the ventilation holes 421 can be adjusted and set as needed, and no specific restrictions are made here.

[0134] It should be noted that, in some other embodiments, the shielding portion 42 may cover the entire return air port 25. In this case, the air inside the outer cylinder 21 may only enter the return air port 25 through the vents 421 and then enter the drying air duct.

[0135] Figure 8 yes Figure 2 A rear view of . Figure 9 yes Figure 8 Middle AA section view. Figure 10 yes Figure 9 Enlarged structural diagram of the D area in the middle.

[0136] like Figure 6 and Figure 10 As shown, in some embodiments, a flow gap space 40 can be formed between the rear wall of the condensation pan 4 and the rear wall inside the outer cylinder 21. Cooler condensate outside the outer cylinder 21 can flow into this flow gap space 40. Thus, the condensate entering the flow gap space 40 can achieve surface-to-surface heat exchange with the condensation pan 4, cooling the condensation pan 4 and improving the cooling efficiency of the condensation pan 4. This allows the condensation pan 4 to maintain a relatively low temperature and continuously exchange heat with the hot and humid air, thereby enabling the condensation pan 4 to continuously condense and dehumidify the hot and humid air, thereby improving the condensation efficiency and uniformity of the hot and humid air.

[0137] like Figure 10 As shown, in some embodiments, the flow-through gap space 40 can be a narrow gap space in the front-to-back direction of the outer cylinder 21. In this way, by providing a smaller flow rate of condensed water, the condensed water can be distributed in a larger portion of the flow-through gap space 40, which is beneficial for increasing the contact area between the condensed water and the condensate pan 4, thereby improving the cooling effect of the condensate pan 4 and avoiding water waste.

[0138] In some embodiments, the width of the flow gap space 40 can be less than 0.3 mm in the front-to-back direction of the outer cylinder 21. Thus, by utilizing a structural design in which the width of the flow gap space 40 can be less than 0.3 mm, a small amount of condensed water can be distributed over a larger area of ​​the flow gap space 40, thereby increasing the contact area between the condensed water and the condensate pan 4, saving water and effectively avoiding water waste.

[0139] In some embodiments, the width of the flow gap space 40 in the front-to-back direction of the outer cylinder 21 can be greater than 0.1 mm. In this way, by making the width of the flow gap space 40 greater than 0.1 mm, the condensed water can smoothly enter the flow gap space 40 and be distributed along the flow gap space 40 to other areas of the flow gap space 40, thereby ensuring the flow rate of the condensed water in the flow gap space 40. In some embodiments, the width of the flow gap space 40 in the front-to-back direction of the outer cylinder 21 ranges from 0.1 mm to 0.3 mm. In this way, by designing the width of the flow gap space 40 to range from 0.1 mm to 0.3 mm, the condensed water can smoothly enter the flow gap space 40, thereby ensuring the flow rate of the condensed water in the flow gap space 40; and a small amount of condensed water can be distributed in a larger area of ​​the flow gap space 40, thereby increasing the contact area between the condensed water and the condensation pan 4.

[0140] In some embodiments, the width of the flow clearance space 40 can be maintained at 0.2 mm in the front-to-back direction of the outer cylinder 21. The back of the condensation pan 4 can be arranged at intervals in front of the rear wall of the outer cylinder 21 so that the width of the flow clearance space 40 can be maintained at 0.2 mm.

[0141] like Figure 5 and Figure 9 As shown, in some embodiments, the range of the flow gap space 40 can be arranged in the entire back side area of ​​the condensation pan 4. In this way, the condensed water in the flow gap space 40 and the condensation pan 4 can have a larger contact area.

[0142] It should be noted that, in other embodiments, the scope of the flow gap space 40 may be smaller than the back side area of ​​the condensation pan 4. The scope and area of ​​the flow gap space 40 may be adjusted as needed and are not specifically limited herein.

[0143] like Figure 5 、 Figure 7 and Figure 10As shown, in some embodiments, a water inlet may be provided on the rear wall of the outer tub 21. The water inlet may be configured to supply condensed water to the flow-through gap space 40. The water inlet may be in communication with the flow-through gap space 40. In this way, condensed water outside the outer tub 21 may enter the flow-through gap space 40 through the water inlet. During the clothes drying process, the water inlet may be controlled to open or close, thereby regulating and controlling the temperature of the condensation pan 4 to maintain a low temperature.

[0144] like Figure 7 and Figure 8 As shown, in some embodiments, the laundry treatment device may include a water inlet valve. The water inlet valve may be arranged in correspondence with the water inlet. The water inlet valve may be configured to open and close the water inlet. Thus, the water inlet can be actively controlled to open or close via the water inlet valve. In conjunction with a corresponding laundry drying program, a corresponding opening or closing program for the water inlet valve can be set to intelligently adjust and control the temperature of the condensation tray 4 to maintain a low temperature.

[0145] It should be noted that in some other embodiments, the water inlet valve can also be used to control the water flow rate and water inlet speed at the water inlet. In this way, the water inlet valve can also actively adjust and control the flow rate and speed of condensed water entering the flow gap space 40 at the water inlet. By setting a corresponding condensed water flow rate and speed adjustment program at the water inlet valve in conjunction with the corresponding clothes drying program, the temperature of the condensate pan 4 can also be intelligently adjusted and controlled to maintain a low temperature.

[0146] In some embodiments, the water inlet valve can be a low-flow valve or a small-flow valve. In this way, the water inlet can provide a small flow of condensed water into the overflow gap space 40, avoiding water resource waste.

[0147] like Figure 7 and Figure 8 As shown, in some embodiments, the laundry treatment device may include a water inlet pipe. The water inlet pipe may be disposed between the water inlet and the water inlet valve. One end of the water inlet pipe may be connected to the water inlet. The other end of the water inlet pipe may be connected to the outlet of the water inlet valve. The inlet of the water inlet valve may be connected to an external water source. In this way, the external water source can supply water to the water inlet through the water inlet valve and the water inlet pipe, thereby enabling the water inlet to provide condensed water into the flow gap space 40.

[0148] like Figure 7 and Figure 8As shown, in some embodiments, the laundry processing device may include multiple water inlets. The multiple water inlets may be arranged at intervals on the rear wall of the outer drum 21. The multiple water inlets may be connected to different areas of the flow-through gap space 40. In this way, different water inlets can supply water to different areas of the flow-through gap space 40, thereby increasing the water inflow rate into the flow-through gap space 40 and improving the cooling efficiency of the condensation pan 4, thereby facilitating the adjustment and control of the temperature of the condensation pan 4 to maintain a low temperature.

[0149] In some embodiments, the laundry treatment device may include multiple water inlet valves. These multiple water inlet valves may be arranged corresponding to multiple water inlets. The multiple water inlet valves may be positioned at corresponding water inlets. In this way, different water inlet valves can control the opening and closing of different water inlets, thereby intelligently regulating and controlling the temperature of the condensation pan 4 to maintain a low temperature.

[0150] In some embodiments, the laundry treatment device may include a plurality of water inlet pipes. The plurality of water inlet pipes may be arranged corresponding to the plurality of water inlets. The plurality of water inlet pipes may be arranged between the drinking water inlet and the water inlet valve.

[0151] like Figure 4 and Figure 5 As shown, in some embodiments, the bottom edge of the overflow gap space 40 can be connected to the interior space of the outer tube 21. Condensed water in the overflow gap space 40 can flow into the interior space of the outer tube 21 through its bottom edge. In this way, when the water inlet provides condensed water to the overflow gap space 40, the condensed water can flow downward along the overflow gap space 40, flow into the interior space of the outer tube 21 through the bottom edge of the overflow gap space 40, and can be discharged through the bottom area of ​​the outer tube 21. In addition, the condensed water in the overflow gap space 40 flows into the interior space of the outer tube 21 through its bottom edge, allowing the condensed water provided by the water inlet to smoothly enter the overflow gap space 40.

[0152] It should be noted that in some other embodiments, the edges at other locations around the flow gap space 40 can also be connected to the internal space of the outer tube 21. In this way, when the water inlet provides condensed water into the flow gap space 40, the condensed water can flow downward along the flow gap space 40 and flow into the internal space of the outer tube 21 through the edges at other locations.

[0153] like Figure 7 and Figure 10As shown, in some embodiments, the multiple water inlets may include a top water inlet 2131. The top water inlet 2131 may be provided on the rear wall of the outer cylinder 21. The top water inlet 2131 may be provided in the top area of ​​the back side of the condensation pan 4. The top water inlet 2131 may be connected to the top area of ​​the flow gap space 40. In this way, the condensed water provided by the top water inlet 2131 can flow into the flow gap space 40 in the area below it, and can flow from the top area of ​​the flow gap space 40 to other areas below it, thereby allowing the condensed water to contact most areas of the entire back side of the condensation pan 4, thereby improving the condensation effect of the condensation pan 4.

[0154] like Figure 7 As shown, in some embodiments, a straight line passing through the axis of the condensation pan along the height direction of the laundry processing device is a first reference line L1, and a plane passing through the first reference line L1 along the depth direction of the laundry processing device is a first reference plane M1. The top water inlet 2131 can be located at the first reference plane M1. The top water inlet 2131 can be located in the top area on the back side of the condensation pan 4. In this way, the condensed water provided by the top water inlet 2131 can flow to the two side areas below it, thereby improving the uniformity of the condensed water distribution in the flow gap space and increasing the flow rate of the condensed water in the flow gap space.

[0155] like Figure 7 and Figure 10 As shown, in some embodiments, the top water inlet 2131 can be designed as a groove. The groove can be recessed and formed on the side wall of the rear wall inside the outer cylinder 21 facing the condensation pan 4. In this way, through the groove design of the top water inlet 2131, the connection area between the top water inlet 2131 and the overflow gap space 40 can be increased. When the top water inlet 2131 provides condensed water to the overflow gap space 40, the condensed water can flow from the peripheral edge of the groove structure to different areas of the overflow gap space 40, which is beneficial to increase the flow speed and flow area of ​​the condensed water in the overflow gap space 40. In addition, the size of the groove can be adjusted as needed and is not limited here.

[0156] like Figure 7 and Figure 8 As shown, in some embodiments, the multiple water inlet valves may include a top water inlet valve 51. The top water inlet valve 51 may be arranged corresponding to the top water inlet 2131. The top water inlet valve 51 may be configured to open and close the top water inlet 2131. The top water inlet valve 51 may also be used to control the water flow rate and water flow rate of the top water inlet 2131. In this way, the top water inlet valve 51 can actively control the opening or closing of the top water inlet 2131, and can also actively adjust and control the flow rate and speed of condensed water entering the flow gap space 40 at the top water inlet 2131.

[0157] In some embodiments, the multiple water inlet pipes may include a top water inlet pipe 61. The top water inlet pipe 61 may be disposed between the top water inlet 2131 and the top water inlet valve 51. One end of the top water inlet pipe 61 may be in communication with the top water inlet 2131. The other end of the top water inlet pipe 61 may be in communication with the outlet of the top water inlet valve 51. The inlet of the top water inlet valve 51 may be connected to an external water source. In this manner, the external water source may supply water to the top water inlet 2131 through the top water inlet valve 51 and the top water inlet pipe 61, thereby enabling the top water inlet 2131 to provide condensed water to the flow gap space 40.

[0158] like Figure 8 and Figure 10 As shown, in some embodiments, a top connecting pipe 213 extending upward is provided at the top of the rear wall of the outer cylinder 21. The groove structure formed by the top water inlet 2131 can be arranged below the top connecting pipe 213. The lower end of the top connecting pipe 213 can be communicated with the top water inlet 2131, and the upper end of the top connecting pipe 213 can be communicated with the top water inlet pipe 61. The top water inlet pipe 61 is sleeved and fixed on the top connecting pipe 213. In this way, when installing the top water inlet pipe 61, the top water inlet pipe 61 can be aligned and sleeved with the top connecting pipe 213, which facilitates the installation and disassembly of the top water inlet pipe 61 and helps to improve the installation efficiency.

[0160] like Figure 7 、 Figure 8 、 Figure 11 and Figure 12 As shown, in some embodiments, the plurality of water inlets may include a first water inlet 2141. The first water inlet 2141 may be disposed on the rear wall of the outer cylinder 21. The first water inlet 2141 may be disposed on the back side of the condensation pan 4. The first water inlet 2141 may be disposed on a side of the condensation pan 4 in a lateral direction. The first water inlet 2141 may be disposed on one side of the first reference plane M1.

[0161] The first water inlet 2141 can be connected to the area of ​​the flow gap space 40 near the first water inlet 2141. In this way, the condensed water provided by the first water inlet 2141 can flow into the flow gap space 40 in the area below it, and can flow from the area on one side of the flow gap space 40 to other areas below it, thereby allowing the condensed water to contact a portion of one side of the condensation pan 4, thereby locally condensing the condensation pan 4.

[0162] like Figure 7 、 Figure 8 and Figure 12As shown, in some embodiments, the multiple water inlet valves may include a first water inlet valve 52. The first water inlet valve 52 may be arranged corresponding to the first water inlet 2141. The first water inlet valve 52 may be configured to open and close the first water inlet 2141. The first water inlet valve 52 may also be used to control the water flow rate and water flow rate of the first water inlet 2141. In this way, the first water inlet valve 52 can actively control the opening or closing of the first water inlet 2141, and can also actively adjust and control the flow rate and speed of condensed water entering the flow gap space 40 at the first water inlet 2141.

[0163] In some embodiments, the plurality of water inlet pipes may include a first water inlet pipe 62. The first water inlet pipe 62 may be disposed between the first water inlet 2141 and the first water inlet valve 52. One end of the first water inlet pipe 62 may be in communication with the first water inlet 2141. The other end of the first water inlet pipe 62 may be in communication with the outlet of the first water inlet valve 52. The inlet of the first water inlet valve 52 may be connected to an external water source. In this manner, the external water source may supply water to the first water inlet 2141 through the first water inlet valve 52 and the first water inlet pipe 62, thereby enabling the first water inlet 2141 to provide condensed water into the flow gap space 40.

[0164] like Figure 8 and Figure 12 As shown, in some embodiments, a first connecting pipe 214 extending rearward is protruded from a lateral side area of ​​the rear wall of the outer cylinder 21. The first water inlet 2141 can be formed at the front end of the first connecting pipe 214. The front end of the first connecting pipe 214 can be connected to the flow gap space 40 through the first water inlet 2141, and the rear end of the first connecting pipe 214 can be connected to the first water inlet pipe 62. The first water inlet pipe 62 can be sleeved and fixed on the first connecting pipe 214. In this way, when installing the first water inlet pipe 62, the first water inlet pipe 62 can be aligned and sleeved with the first connecting pipe 214, which facilitates the installation and removal of the first water inlet pipe 62 and helps to improve the installation efficiency.

[0166] like Figure 7 、 Figure 8 、 Figure 13 and Figure 14As shown, in some embodiments, the plurality of water inlets may include a second water inlet 2151. The second water inlet 2151 may be disposed on the rear wall of the outer cylinder 21. The second water inlet 2151 may be disposed on the back side of the condensation pan 4. The second water inlet 2151 may be disposed on the other side of the condensation pan 4 in the transverse direction. The second water inlet 2151 may be disposed on a side of the first reference plane M1 away from the first water inlet 2141.

[0167] The second water inlet 2151 can be connected to the area of ​​the flow gap space 40 on the side close to the second water inlet 2151. In this way, the condensed water provided by the second water inlet 2151 can flow into the flow gap space 40 in the area below it, and can flow from the other side of the flow gap space 40 to other areas below it, thereby allowing the condensed water to contact a portion of the other side of the condensation pan 4, thereby locally condensing the condensation pan 4.

[0168] In some embodiments, the first water inlet 2141 and the second water inlet 2151 can be provided on opposite sides of the first reference plane M1. In this way, the condensation pan 4 on opposite sides of the first reference plane M1 can be partially condensed by the first water inlet and the second water inlet 2151, thereby condensing the local areas on opposite sides of the condensation pan 4. Figure 7 、 Figure 8 and Figure 14 As shown, in some embodiments, the multiple water inlet valves may include a second water inlet valve 53. The second water inlet valve 53 may be arranged corresponding to the second water inlet 2151. The second water inlet valve 53 may be configured to open and close the second water inlet 2151. The second water inlet valve 53 may also be used to control the water flow rate and water flow rate of the second water inlet 2151. In this way, the second water inlet valve 53 can actively control the opening or closing of the second water inlet 2151, and can also actively adjust and control the flow rate and speed of condensed water entering the flow gap space 40 at the second water inlet 2151.

[0169] In some embodiments, the plurality of water inlet pipes may include a second water inlet pipe 63. The second water inlet pipe 63 may be disposed between the second water inlet 2151 and the second water inlet valve 53. One end of the second water inlet pipe 63 may be in communication with the second water inlet 2151. The other end of the second water inlet pipe 63 may be in communication with the outlet of the second water inlet valve 53. The inlet of the second water inlet valve 53 may be connected to an external water source. In this manner, the external water source may supply water to the second water inlet 2151 through the second water inlet valve 53 and the second water inlet pipe 63, thereby enabling the second water inlet 2151 to provide condensed water into the flow gap space 40.

[0170] like Figure 8 and Figure 14As shown, in some embodiments, a second connecting pipe 215 extending rearward is protruded from a lateral side area of ​​the rear wall of the outer cylinder 21. A second water inlet 2151 can be formed at a front end of the second connecting pipe 215. The front end of the second connecting pipe 215 can be connected to the flow gap space 40 through the second water inlet 2151, and the rear end of the second connecting pipe 215 can be connected to the second water inlet pipe 63. The second water inlet pipe 63 can be sleeved and fixed on the second connecting pipe 215. In this way, when installing the second water inlet pipe 63, the second water inlet pipe 63 can be aligned and sleeved with the second connecting pipe 215, which facilitates the installation and removal of the second water inlet pipe 63 and helps improve installation efficiency.

[0171] like Figure 6 、 Figure 7 and Figure 8 As shown, as mentioned above, in some embodiments, when the multiple water inlets include the top water inlet 2131, the first water inlet 2141 and the second water inlet 2151, during the drying process, the temperature of the condensation tray 4 can be monitored in real time, and the opening and closing states of the top water inlet 2131, the first water inlet 2141 and the second water inlet 2151 can be autonomously controlled according to the real-time temperature state of the condensation tray 4, thereby intelligently adjusting the cooling efficiency of the condensation water on the condensation tray 4, intelligently adjusting and controlling the temperature of the condensation tray 4, so that the condensation tray 4 remains in a low temperature state, and achieving the effect of saving water and improving efficiency.

[0172] For example, during the drying process, the temperature of the condensation tray 4 may be divided into a first temperature interval, a second temperature interval, a third temperature interval, and a fourth temperature interval from high to low according to the temperature of the condensation tray 4 .

[0173] When the temperature of condensate pan 4 is in the highest first temperature range, top water inlet 2131, first water inlet 2141, and second water inlet 2151 can be opened simultaneously. This allows continuous condensation over a large portion of condensate pan 4 through top water inlet 2131, while first water inlet 2141 and second water inlet 2151 provide localized condensation over condensate pan 4 on opposite sides of first reference plane M1. At this point, top water inlet 2131, first water inlet 2141, and second water inlet 2151 continuously cooperate, achieving the highest cooling efficiency for condensate pan 4.

[0174] When the temperature of condensate pan 4 drops to the second temperature range, top water inlet 2131 can remain open, while first water inlet 2141 and second water inlet 2151 can be opened alternately. This allows continuous condensation over a large portion of condensate pan 4 through top water inlet 2131, while localized condensation over condensate pan 4 on opposite sides of first reference plane M1 is achieved alternately through first water inlet 2141 and second water inlet 2151. At this point, the alternating operation of first water inlet 2141 and second water inlet 2151 reduces the cooling efficiency of condensate pan 4 and the required cooling capacity of the condensate pan. This ensures continuous condensation in the condensate pan, helps maintain a uniform temperature distribution over condensate pan 4, and helps conserve water and prevent waste.

[0175] When the temperature of condensate pan 4 drops to the third temperature range, top water inlet 2131 can remain open, while first water inlet 2141 and second water inlet 2151 can remain closed. This allows condensation to continue over a large portion of condensate pan 4 through top water inlet 2131 alone. At this point, the cooling efficiency of condensate pan 4 continues to decrease, and top water inlet 2131 is sufficient to maintain the cooling of condensate pan 4. This ensures continuous condensation in condensate pan 4, further conserving water and preventing water waste.

[0176] When the temperature of the condensation pan 4 drops to the fourth temperature range, the top water inlet 2131, the first water inlet 2141 and the second water inlet 2151 can be closed, so that the condensation pan 4 can be kept at a continuous low temperature.

[0177] like Figure 7 and Figure 8As shown, in some embodiments, a straight line passing through the axis of the condenser pan 4 along the width direction of the laundry treatment device is a second reference line L2, and a plane passing through the second reference line L2 along the depth direction of the laundry treatment device is a second reference plane M2. When the multiple water inlets include a top water inlet 2131, a first water inlet 2141, and a second water inlet 2151, the top water inlet 2131 can be located at the top area of ​​the rear wall of the outer tub 21, and the first water inlet 2141 and the second water inlet 2151 can be located on opposite sides of the first reference plane M1. The first water inlet 2141 and the second water inlet 2151 can be located on the second reference plane M2. The first water inlet 2141 and the second water inlet 2151 can be located on opposite sides of the center of the rear wall of the outer tub 21. In this way, the first water inlet 2141 and the second water inlet 2151 can be distributed at 90° to the left and right sides of the top water inlet 2131, so that the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be 90°, and the angle β between the line connecting the second water inlet 2151 and the axis of the condensation pan 4 and the first reference line L1 can be 90°. In this way, the top water inlet 2131, the first water inlet 2141, and the second water inlet 2151 can be relatively evenly distributed on the back side of the condensation pan 4, which helps to increase the contact area between the condensed water and the condensation pan 4, thereby improving the cooling effect on the condensation pan 4 and avoiding water waste.

[0178] In some embodiments, the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be between 85° and 95°. This allows the first water inlet 214 to be positioned within a certain range above and below the second reference plane M2, ensuring that the top water inlet 2131, the first water inlet 2141, and the second water inlet 2151 are relatively evenly distributed on the back side of the condensation pan 4. This also reduces the precision requirements for the position of the first water inlet 2141, thereby reducing manufacturing difficulty and cost.

[0179] In some embodiments, the angle β between the line connecting the second water inlet 2151 and the axis of the condensation pan 4 and the first reference line L1 can be between 85° and 95°. This allows the second water inlet 2151 to be positioned within a certain range above and below the second reference plane M2, ensuring a relatively even distribution of the top water inlet 2131, the first water inlet 2141, and the second water inlet 2151 on the back side of the condensation pan 4. This also reduces the precision requirements for the positioning of the second water inlet 2151, thereby reducing manufacturing complexity and costs. In some embodiments, the second water inlet 2151 and the return air inlet 25 can be located on the same side of the first reference plane M1. The second water inlet 2151 can be located below the return air inlet 25.

[0180] In some embodiments, when the multiple water inlets include a top water inlet 2131, a first water inlet 2141, and a second water inlet 2151, the top water inlet 2131 can be located on the first reference plane M1. The top water inlet 2131 can be located at the top region of the back of the outer cylinder 21. The first water inlet 2141 can be located above the second reference plane M2. The second water inlet 2151 can be located above the second reference plane M2. Furthermore, the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be greater than 85°. Furthermore, the angle α between the line connecting the second water inlet 2151 and the axis of the condensation pan 4 and the first reference line L1 can be greater than 85°. In this way, a sufficient distance can be maintained between the top water inlet 2131 and the first water inlet 2141, which helps to increase the contact area and contact surface between the condensed water provided by the top water inlet 2131 and the first water inlet 2141 and the back side of the condensation pan 4, thereby facilitating a uniform temperature distribution on the condensation pan 4. A sufficient distance can also be maintained between the top water inlet 2131 and the second water inlet 2151, which helps to increase the contact area and contact surface between the condensed water provided by the top water inlet 2131 and the second water inlet 2151 and the back side of the condensation pan 4, thereby facilitating a uniform temperature distribution on the condensation pan 4.

[0181] In some embodiments, when the multiple water inlets include a top water inlet 2131, a first water inlet 2141, and a second water inlet 2151, the top water inlet 2131 can be located on the first reference plane M1. The top water inlet 2131 can be located in the top area of ​​the back of the outer cylinder 21. The first water inlet 2141 can be located below the second reference plane M2. The second water inlet 2151 can be located below the second reference plane M2. Furthermore, the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be less than 95°. Furthermore, the angle α between the line connecting the second water inlet 2151 and the axis of the condensation pan 4 and the first reference line L1 can be less than 95°. This ensures that the first water inlet 2141 is at a sufficient height, which helps increase the contact area and surface area between the condensed water provided by the first water inlet 2141 and the back of the condensation pan 4, thereby facilitating uniform temperature distribution on the condensation pan 4. The second water inlet 2151 can be kept at a sufficient height, which is beneficial to increasing the contact area and contact surface between the condensed water provided by the second water inlet 2151 and the back side of the condensation pan 4, and is beneficial to making the temperature distribution of the condensation pan 4 uniform.

[0182] like Figure 7 and Figure 8 As shown, in some embodiments, the laundry processing device may include a temperature sensor 7. The temperature sensor 7 may be disposed on the rear wall of the outer tub 21. One end of the temperature sensor 7 may extend into the interior of the outer tub 21 and contact the back of the condensation pan 4, thereby detecting and monitoring the temperature of the condensation pan 4 in real time.

[0183] In some embodiments, when the multiple water inlets include top water inlet 2131, first water inlet 2141, and second water inlet 2151, temperature sensor 7 can be located at a position on the back of condensation pan 4, away from top water inlet 2131, first water inlet 2141, and second water inlet 2151. One end of temperature sensor 7 can contact the bottom area of ​​the back of condensation pan 4. In this way, the bottom area of ​​the back of condensation pan 4 can be the farthest area from top water inlet 2131, first water inlet 2141, and second water inlet 2151, and can be the location where temperature sensor 7 can more accurately detect the temperature of condensation pan 4.

[0184] It should be noted that, in other embodiments, one end of the temperature sensor 7 may also be in contact with other partial areas of the back of the condensation pan 4 to detect and monitor the temperature of the condensation pan 4 .

[0185] Figure 15 yes Figure 7 Structural diagrams in other embodiments.

[0186] like Figure 15 As shown, in some embodiments, the multiple water inlets are two water inlets, including a top water inlet 2131 and a first water inlet 2141. In this embodiment, the second water inlet 2151 is not provided. In this case, during the drying process, when the temperature of the condensation tray 4 is high, the top water inlet 2131 and the first water inlet 2141 can simultaneously provide condensed water to the flow gap space 40. In this way, the condensed water provided by the top water inlet 2131 can flow into the flow gap space 40 in the area below it, thereby condensing the majority of the condensation tray 4. The condensed water provided by the first water inlet 2141 can flow into the flow gap space 40 in the area below it, thereby condensing the condensation tray 4 in a local area. The two working together can improve the cooling efficiency of the condensation tray 4 and quickly cool the condensation tray 4.

[0187] In some embodiments, when the temperature of the condensate pan 4 decreases, the top water inlet 2131 can continue to supply condensate to the flow gap space 40, and the first water inlet 2141 can intermittently supply condensate to the flow gap space 40. In this way, the top water inlet 2131 continuously condenses most of the condensate pan 4, while the first water inlet 2141 intermittently condenses part of the condensate pan 4. This can reduce the amount of water entering the first water inlet 2141, thereby saving water. At the same time, the condensate pan 4 can continue to be condensed, so that the temperature of the condensate pan 4 continues to decrease.

[0188] In some embodiments, as the temperature of the condensate pan 4 continues to decrease, the top water inlet 2131 can continue to supply condensate to the flow gap space 40, while the first water inlet 2141 can stop supplying condensate to the flow gap space 40. In this way, by continuing to condense the majority of the condensate pan 4 only through the top water inlet 2131, the amount of water entering the first water inlet 2141 can be further reduced, further conserving water, while still maintaining condensation in the condensate pan 4 and allowing the condensate pan 4 to continue to cool.

[0189] In some embodiments, when the temperature of the condensate pan 4 continues to decrease, the top water inlet 2131 and the first water inlet 2141 can stop supplying condensate to the flow gap space 40. In this way, when the temperature of the condensate pan 4 is lower than the preset temperature, condensate does not need to be supplied to the flow gap space 40.

[0190] like Figure 15 As shown, as mentioned above, in some embodiments, when the multiple water inlets only include the top water inlet 2131 and the first water inlet 2141, during the drying process, the temperature of the condensation tray 4 can be monitored in real time, and the opening and closing states of the top water inlet 2131 and the first water inlet 2141 can be autonomously controlled according to the real-time temperature state of the condensation tray 4, thereby intelligently adjusting the cooling efficiency of the condensation water on the condensation tray 4, intelligently adjusting and controlling the temperature of the condensation tray 4, so that the condensation tray 4 remains in a low temperature state, and achieving the effect of saving water and improving efficiency.

[0191] For example, during the drying process, the temperature of the condensation tray 4 may be divided into a first temperature interval, a second temperature interval, a third temperature interval, and a fourth temperature interval from high to low according to the temperature of the condensation tray 4 .

[0192] When the temperature of the condensation pan 4 is in the highest first temperature range, the top water inlet 2131 and the first water inlet 2141 can be opened at the same time. At this time, the cooling efficiency of the condensation pan 4 by the condensed water is the highest.

[0193] When the temperature of the condensation pan 4 drops to the second temperature range, the top water inlet 2131 can remain open and the first water inlet 2141 can be opened intermittently. At this time, the cooling efficiency of the condensation pan 4 by the condensed water is relatively reduced.

[0194] When the temperature of the condensation pan 4 drops to the third temperature range, the top water inlet 2131 can remain open and the first water inlet 2141 can be closed. At this time, the cooling efficiency of the condensation pan 4 by the condensed water continues to decrease.

[0195] When the temperature of the condensation pan 4 drops to the fourth temperature range, the top water inlet 2131 and the first water inlet 2141 can be closed, so that the condensation pan 4 is kept in a low temperature state.

[0196] like Figure 15As shown, as previously described, in some embodiments, when the multiple water inlets include only the top water inlet 2131 and the first water inlet 2141, the top water inlet 2131 can be located on the first reference plane M1, or in the top region of the back of the outer cylinder 21. The first water inlet 2141 can be located above the second reference plane M2. Furthermore, the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be greater than 20°. This maintains a sufficient distance between the top water inlet 2131 and the first water inlet 2141, facilitating increased contact area between the condensed water provided by the top water inlet 2131 and the first water inlet 2141 and the back of the condensation pan 4, thereby facilitating uniform temperature distribution on the condensation pan 4.

[0197] In some embodiments, when the multiple water inlets include only the top water inlet 2131 and the first water inlet 2141, the top water inlet 2131 can be located on the first reference plane M1, or in the top region of the back of the outer cylinder 21. The first water inlet 2141 can be located above the second reference plane M2. Furthermore, the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be less than 45°. This ensures that the first water inlet 2141 is at a sufficient height, positioned as close as possible to the top region of the back side of the condensation pan 4. This helps increase the contact area and surface area between the condensed water provided by the first water inlet 2141 and the back side of the condensation pan 4, thereby facilitating uniform temperature distribution on the condensation pan 4.

[0198] In some embodiments, when the multiple water inlets include only the top water inlet 2131 and the first water inlet 2141, the top water inlet 2131 can be located on the first reference plane M1, or in the top region of the back of the outer cylinder 21. The first water inlet 2141 can be located above the second reference plane M2. Furthermore, the angle α between the line connecting the first water inlet 2141 and the axis of the condensation pan 4 and the first reference line L1 can be between 20° and 45°. This ensures a sufficient distance between the top water inlet 2131 and the first water inlet 2141, while also ensuring a sufficient height for the first water inlet 2141 to be located as close to the top region of the back of the condensation pan 4 as possible. This helps increase the contact area between the condensed water provided by the top water inlet 2131 and the first water inlet 2141 and the back of the condensation pan 4, thereby facilitating a uniform temperature distribution on the condensation pan 4.

[0199] In some embodiments, the return air vent 25 can be located on the other side of the first reference plane M1. The first water inlet 2141 and the return air vent 25 can be located on opposite sides of the first reference plane M1. This prevents the first water inlet 2141 and the return air vent 25 from being located on the same side, thus preventing the return air vent 25 from affecting the position of the first water inlet 2141.

[0200] Figure 16 yes Figure 5 A structural diagram of the condensation tray 4. Figure 17 yes Figure 16 The structure of the condensation plate 4 is shown from another perspective.

[0201] like Figure 10 、 Figure 16 and Figure 17 As shown, in some embodiments, the back side of the condensation pan 4 may be recessed toward the front side thereof to form a water channel 44. The water channel 44 may be enclosed in the area between the back side of the condensation pan 4 and the rear wall of the outer cylinder 21. The water channel 44 may communicate with the flow-through gap space 40. The water channel 44 may be arranged in the area where the flow-through gap space 40 is located. A water inlet may communicate with the water channel 44. The water inlet may be configured to supply condensed water to the water channel 44.

[0202] Thus, when the water inlet valve is opened and condensed water is supplied from the water inlet, the condensed water supplied from the water inlet can flow into the waterway channel 44, flow to the waterway channel 44 below it, and flow through the edge of the waterway channel 44 to the flow gap space 40 below it, thereby allowing the water inlet to supply condensed water to the flow gap space 40. In addition, the condensed water supplied from the water inlet can flow quickly along the waterway channel 44 to different areas of the condensation pan 4 and the flow gap space 40, thereby increasing the dispersion speed of the condensed water and the speed at which the condensed water enters the flow gap space 40.

[0203] It should be noted that, in some other embodiments, the water channel 44 may be recessed on the rear wall inside the outer cylinder 21 , or the water channel 44 may be enclosed between the rear condensation pan 4 and the rear wall of the outer cylinder 21 .

[0204] like Figure 10As shown, in some embodiments, the top water inlet 2131 is connected to the water channel 44 in the top area of ​​the back side of the condensation pan 4. The condensed water provided by the top water inlet 2131 can flow into the water channel 44 in the top area of ​​the back side of the condensation pan 4 and then flow into the flow gap space 40 below it through the water channel 44. In this way, the condensed water provided by the top water inlet 2131 can flow into the flow gap space 40 below through the water channel 44 in the top area, improving the dispersion efficiency of the condensed water. In turn, the condensed water can contact and condense in various areas on the back side of the condensation pan 4, which is conducive to achieving condensation in most areas of the condensation pan 4.

[0205] like Figure 12 As shown, in some embodiments, the first water inlet 2141 is connected to the water channel 44 in the lateral side area of ​​the back side of the condensation pan 4. The condensed water provided by the first water inlet 2141 can flow into the water channel 44 in the lateral side area of ​​the back side of the condensation pan 4 and then flow into the flow gap space 40 below it through the water channel 44. In this way, the condensed water provided by the first water inlet 2141 can flow into the flow gap space 40 below through the water channel 44 in the side area, thereby improving the dispersion efficiency of the condensed water and allowing the condensed water to contact and condense in the side area of ​​the back side of the condensation pan 4, which is conducive to achieving local condensation in the side area of ​​the condensation pan 4.

[0206] like Figure 14 As shown, in some embodiments, the second water inlet 2151 is connected to the water channel 44 in the other lateral region of the back side of the condensation pan 4. The condensed water provided by the second water inlet 2151 can flow into the water channel 44 in the other lateral region of the back side of the condensation pan 4 and then flow through the water channel 44 into the flow gap space 40 below. In this way, the condensed water provided by the second water inlet 2151 can flow through the water channel 44 in the other lateral region into the flow gap space 40 below, improving the dispersion efficiency of the condensed water. This allows the condensed water to contact and condense in the other lateral region of the back side of the condensation pan 4, thereby facilitating the localized condensation of the other lateral region of the condensation pan 4.

[0207] Figure 18 yes Figure 16 rear view.

[0208] like Figure 17 and Figure 18 As shown, in some embodiments, the plurality of water channels 44 may include an annular first water channel 441. The first water channel 441 may be arranged around the center of the condensate pan 4. The first water channel 441 may be arranged around the center of the rear wall of the outer cylinder 21. As such, as the condensate flows along the first water channel 441, it can be quickly dispersed to various areas on the back side of the condensate pan 4 and can quickly disperse into the flow gap space 40.

[0209] In some embodiments, multiple first water channels 441 may be provided. Multiple first water channels 441 may be sequentially spaced around the center of the condensate pan 4. In this manner, condensed water can flow simultaneously along multiple first water channels 441, thereby further increasing the dispersion rate of the condensed water and the speed at which the condensed water enters the flow gap space 40.

[0210] like Figure 17 and Figure 18 As shown, in some embodiments, a first water channel 441 can be arranged at the edge of the condensation pan 4 near the annular center. Another first water channel 441 can be arranged at the peripheral edge of the condensation pan 4. In this way, when the condensed water flows along the first water channel 441, it can be further dispersed to various areas on the back side of the condensation pan 4, which can further increase the speed at which the condensed water enters the flow gap space 40.

[0211] like Figure 17 and Figure 18 As shown, in some embodiments, the plurality of waterway channels 44 may include a second waterway channel 442. The second waterway channel 442 may be disposed between the plurality of first waterway channels 441. The second waterway channel 442 may extend radially along the condensate pan 4. The second waterway channel 442 may connect two adjacent first waterway channels 441. The second waterway channel 442 may also connect multiple adjacent first waterway channels 441. In this manner, the water inlet may be connected only to the first waterway channel 441 or only to the second waterway channel 442, allowing condensed water provided by the water inlet to flow through both the first waterway channel 441 and the second waterway channel 442.

[0212] In some embodiments, the plurality of water channels 44 may include a plurality of second water channels 442. The plurality of second water channels 442 may be circumferentially spaced around the center of the condensate pan 4. The plurality of second water channels 442 may be connected to the plurality of first water channels 441, respectively. This can increase the rate at which condensed water provided by the water inlet is dispersed through the first and second water channels 441, 442, thereby increasing the rate at which the condensed water enters the flow gap space 40.

[0213] Figure 19 yes Figure 16 Front view of .

[0214] like Figure 10 、 Figure 16 and Figure 19 As shown, in some embodiments, the front wall of the condensation pan 4 may be formed with condensation ribs 45 protruding toward the front side thereof and arranged corresponding to the water channel 44. The condensation ribs 45 can increase the contact area between the condensation pan 4 and the hot and humid air, thereby improving the condensation efficiency of the condensation pan 4 for the hot and humid air.

[0215] In some embodiments, the water channel 44 and the condensation ribs 45 can be integrally stamped on the rear and front walls of the condensation pan 4. This allows for simple and convenient stamping of the water channel 44 and the condensation ribs 45 on the condensation pan 4, simplifying the processing of the condensation pan 4 and improving production efficiency.

[0216] like Figure 16 and Figure 19 As shown, in some embodiments, the condensation ribs 45 may include a first condensation rib 451. The first condensation rib 451 may be provided on the front wall of the condensation pan 4. The first condensation rib 451 may be arranged corresponding to the first water channel 441. The first condensation rib 451 may be arranged around the center of the condensation pan 4.

[0217] In some embodiments, a plurality of first condensation ribs 451 may be provided, and the plurality of first condensation ribs 451 may be arranged in a one-to-one correspondence with the plurality of first waterway channels 441 .

[0218] like Figure 16 and Figure 19 As shown, in some embodiments, the condensation rib 45 may include a second condensation rib 452. The second condensation rib 452 may be formed on the front wall of the condensation pan 4. The second condensation rib 452 may be arranged corresponding to the second waterway channel 442. The second condensation rib 452 may extend in the radial direction of the condensation pan 4.

[0219] In some embodiments, a plurality of second condensation ribs 452 may be provided, and the plurality of second condensation ribs 452 may be arranged in a one-to-one correspondence with the plurality of second waterway channels 442 .

[0220] like Figure 17 and Figure 18 As shown, in some embodiments, a plurality of support portions 46 may be provided protruding from the back of the condensation pan 4. The plurality of support portions 46 may be arranged at intervals. When the condensation pan 4 is fixed to the front side of the rear wall of the outer cylinder 21, the plurality of support portions 46 may abut against the rear wall of the outer cylinder 21, thereby forming a flow gap space 40 of a certain width between the back of the condensation pan 4 and the rear wall of the outer cylinder 21.

[0221] In some embodiments, the protruding heights of the multiple support portions 46 can be the same. The protruding heights of the multiple support portions 46 can be between 0.1 mm and 0.3 mm. For example, the protruding height of the support portions 46 can be 0.2 mm. In this way, when the condensation pan 4 abuts against the rear wall of the outer cylinder 21 via the multiple support portions 46, a flow clearance space 40 with a width of 0.1 mm to 0.3 mm can be formed between the back surface of the condensation pan 4 and the rear wall of the outer cylinder 21.

[0222] It should be noted that, in some other embodiments, multiple support portions 46 may also be provided on the rear wall of the outer cylinder 21. When the condensation pan 4 is fixed to the front side of the rear wall of the outer cylinder 21, the condensation pan 4 can abut against the multiple support portions 46. That is, the condensation pan 4 can abut against the rear wall of the outer cylinder 21 via the multiple support portions 46, thereby forming a flow gap space 40 of a certain width between the back side of the condensation pan 4 and the rear wall of the outer cylinder 21.

[0223] like Figure 17 As shown, in some embodiments, the support portion 46 can be annular. The support portion 46 can be arranged around the peripheral edge of the second fixing hole 41. Alternatively, the second fixing hole 41 can be arranged through the center of the support portion 46. In this way, when a screw is inserted into the second fixing hole 41 of the condensation pan 4 and fixed in the first fixing hole 212, the support portion 46 can abut against the rear wall of the outer cylinder 21, thereby maintaining a stable distance between the back of the condensation pan 4 and the rear wall of the outer cylinder 21, and thus maintaining a stable gap width of the flow clearance space 40.

[0224] like Figure 7 As shown, in some embodiments, the return air outlet 25 can be provided on one side of the top water inlet 2131 on the rear wall inside the outer cylinder 21. An isolation rib 216 can be protrudingly provided on the rear wall inside the outer cylinder 21. The isolation rib 216 can be provided between the top water inlet 2131 and the return air outlet 25. The isolation rib 216 can be arranged in a long strip shape. The isolation rib 216 can be used to isolate the top water inlet 2131 and the return air outlet 25. In this way, when the top water inlet 2131 provides condensed water to the overflow gap space 40, the isolation rib 216 can effectively prevent the condensed water at the top water inlet 2131 from flowing into the return air outlet 25.

[0225] In some embodiments of the present application, the laundry treatment device may include a control unit. The control unit may be electrically connected to the temperature sensor 7.

The operating states of the first water inlet valve and the second water inlet valve can be switched and controlled based on the real-time temperature of the condensate pan.

[0235] In some embodiments of the present application, the operating states of the top water inlet valve, the first water inlet valve, and the second water inlet valve can be switched and controlled according to the real-time temperature of the condensation tray.

[0236] In some embodiments of the present application, the working state may include an on state. The working state may include a off state. The working state may include an on state and a off state.

[0237] When the water inlet valve is in the open state, the corresponding water inlet provides condensed water. When the water inlet valve is in the closed state, the corresponding water inlet stops providing condensed water.

[0238] In some embodiments of the present application, when the top water inlet valve is in an open state, the corresponding top water inlet provides condensed water. When the top water inlet valve is in a closed state, the corresponding top water inlet stops providing condensed water.

[0240] In some embodiments of the present application, when the second water inlet valve is in an open state, the corresponding second water inlet provides condensed water, and when the second water inlet valve is in a closed state, the corresponding second water inlet stops providing condensed water.

[0241] Figure 20 This is a flowchart of steps that can be executed by the control unit of some embodiments of the present invention.

[0242] like Figure 20 As shown, in some embodiments of the present application, the control unit may be configured to execute the following S110-S190:

[0243] S110: If it is detected that the real-time temperature of the temperature sensor is above the first set temperature, the top water inlet valve, the first water inlet valve and the second water inlet valve are controlled to open.

[0244] S110, obtaining the real-time temperature of the temperature sensor.

[0245] S120, determining whether the real-time temperature of the temperature sensor is above a first set temperature.

[0246] S130: If the answer is yes, the top water inlet valve, the first water inlet valve and the second water inlet valve are controlled to open.

[0247] S140 , determining whether the real-time temperature of the temperature sensor is within a temperature range between a first set temperature and a second set temperature.

[0248] S150: If the answer is yes, the top water inlet valve is controlled to be opened, and the first water inlet valve and the second water inlet valve are controlled to be opened alternately according to the first set frequency.

[0249] S160: Determine whether the real-time temperature of the temperature sensor is within a temperature range between the second set temperature and the third set temperature.

[0250] S170: If the answer is yes, the top water inlet valve, the first water inlet valve and the second water inlet valve are alternately opened according to the second set frequency control.

[0251] S180, determining whether the real-time temperature of the temperature sensor is below a third set temperature.

[0252] S190: If the answer is yes, the top water inlet valve, the first water inlet valve and the second water inlet valve are controlled to be closed.

[0253] The above S110-S190 are respectively described in detail below.

[0254] In S110 , the temperature sensor may be used to detect the temperature of the condensation pan. The real-time temperature of the temperature sensor may reflect the real-time temperature of the condensation pan.

[0255] In S120-S130, in some embodiments of the present application, if it is detected that the real-time temperature of the temperature sensor is above the first set temperature, indicating that the current temperature of the condensation tray is too high, the top water inlet valve, the first water inlet valve and the second water inlet valve can be controlled to open.

[0256] In some embodiments of the present application, the first set temperature may be 50 degrees Celsius. The first set temperature may also be 55 degrees Celsius. This embodiment does not limit the specific value of the first set temperature.

[0257] In some embodiments of the present application, the first temperature range may be above the first set temperature.

[0258] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be above 50 degrees Celsius, indicating that the current temperature of the condensation tray is too high, the top water inlet valve, the first water inlet valve and the second water inlet valve can be controlled to open.

[0259] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be above the first set temperature, indicating that the current temperature of the condensation tray is too high, the top water inlet valve, the first water inlet valve and the second water inlet valve can be controlled to open to effectively reduce the temperature of the condensation tray. By effectively reducing the temperature of the condensation tray, the heat exchange efficiency of the condensation tray can be improved, thereby improving the condensation efficiency of the condensation tray.

[0260] In S140-S150, in some embodiments of the present application, if it is detected that the real-time temperature of the temperature sensor is in the temperature range between the first set temperature and the second set temperature, indicating that the current temperature of the condensation tray is high but not too high, the top water inlet valve can be controlled to be opened, and the first water inlet valve and the second water inlet valve can be controlled to be opened alternately according to the first set frequency.

[0261] In some embodiments of the present application, the second set temperature is lower than the first set temperature.

[0262] In some embodiments of the present application, a temperature range between the first set temperature and the second set temperature may serve as the second temperature range.

[0263] In some embodiments of the present application, the second set temperature may be 30 degrees Celsius. The second set temperature may be 40 degrees Celsius. This embodiment does not limit the specific value of the second set temperature.

[0264] In some embodiments of the present application, the first set frequency may be 30 seconds. The first set frequency may be 35 seconds. This embodiment does not limit the specific value of the first set frequency.

[0265] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range of 30 degrees Celsius to 50 degrees Celsius, indicating that the current temperature of the condensation tray is high but not too high, the top water inlet valve can be controlled to open, and the first water inlet valve and the second water inlet valve can be controlled to open alternately at a frequency of 30 seconds.

[0266] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be within the temperature range of the first set temperature and the second set temperature, indicating that the current temperature of the condensation tray is high but not too high, the top water inlet valve can be controlled to open, and the first water inlet valve and the second water inlet valve can be controlled to open alternately according to the first set frequency. This can ensure that the temperature of the condensation tray is effectively lowered while avoiding all water inlet valves being in the open state all the time and causing water waste.

[0267] In S160-S170, in some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range between the second set temperature and the third set temperature, indicating that the current temperature of the condensation pan is not high but not too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be alternately opened according to the second set frequency control.

[0268] In some embodiments of the present application, the third set temperature is lower than the second set temperature.

[0269] In some embodiments of the present application, a temperature range between the second set temperature and the third set temperature may serve as the third temperature range.

[0270] In some embodiments of the present application, the third set temperature may be 20 degrees Celsius. The third set temperature may be 25 degrees Celsius. This embodiment does not limit the specific value of the third set temperature.

[0271] In some embodiments of the present application, the second set frequency is greater than the first set frequency.

[0272] In some embodiments of the present application, the second set frequency may be 45 seconds. The second set frequency may be 50 seconds. This embodiment does not limit the specific value of the second set frequency.

[0273] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range of 20 degrees Celsius to 30 degrees Celsius, indicating that the current temperature of the condensation tray is not high but not too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be alternately opened at a frequency of 45 seconds.

[0274] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be in the temperature range between the second set temperature and the third set temperature, indicating that the current temperature of the condensation tray is not high but not too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be alternately opened according to the second set frequency control, thereby ensuring that the temperature of the condensation tray is effectively lowered while avoiding all water inlet valves being in the open state all the time and causing water waste.

[0275] In S180-S190, if it is detected that the real-time temperature of the temperature sensor is below the third set temperature, indicating that the current temperature of the condensation tray is too low, the top water inlet valve, the first water inlet valve and the second water inlet valve may be controlled to be closed.

[0276] In some embodiments of the present application, the temperature below the third set temperature can be used as the fourth temperature interval.

[0277] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be below 20 degrees Celsius, indicating that the current temperature of the condensation tray is too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be controlled to close.

[0278] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be below the third set temperature, indicating that the current temperature of the condensation tray is too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be controlled to close, thereby ensuring the condensation efficiency of the condensation tray while avoiding waste of water resources.

[0279] In some embodiments of the present application, the control unit may be configured to execute the following:

[0280] If the control simultaneously opens the top water inlet valve, the first water inlet valve and the second water inlet valve for more than a first set time, and detects that the temperature of the temperature sensor still reaches above the set temperature limit, the control will issue an alarm.

[0281] Furthermore, in some embodiments of the present application, the first set duration may be 10 minutes. The first set duration may be 15 minutes. This embodiment does not limit the specific value of the first set duration.

[0282] In some embodiments of the present application, the set temperature limit value may be 50 degrees Celsius. The set temperature limit value may be 40 degrees Celsius. This embodiment does not limit the specific value of the set temperature limit value.

[0283] In some embodiments of the present application, if the top water inlet valve, the first water inlet valve and the second water inlet valve are controlled to be opened simultaneously for more than 10 minutes, and the temperature of the temperature sensor is detected to be still above 50 degrees Celsius, indicating that the condensate may be flowing out abnormally at this time, an alarm can be controlled to alert the user of the abnormal situation.

[0284] From the above, it can be seen that if the top water inlet valve, the first water inlet valve and the second water inlet valve are opened at the same time for more than the first set time, but the temperature of the condensation tray still reaches above the set temperature limit, indicating that the condensation water may be abnormal at this time, an alarm can be controlled to remind the user of the abnormal situation.

[0285] Figure 21This is a flowchart of steps that can be executed by the control unit of other embodiments of the present invention.

[0286] like Figure 21 As shown, in some embodiments of the present application, the control unit may be configured to execute the following S210-S230:

[0287] S210, obtaining the real-time temperature of the temperature sensor at a first moment and the real-time temperature at a second moment; the first moment and the second moment are separated by a second set time period.

[0288] S220: Determine whether the difference between the real-time temperature at the first moment and the real-time temperature at the second moment is below a preset temperature change value.

[0289] S230: If it is detected that the difference is below the temperature change value, the control generates an alarm.

[0290] The above S210-S230 are respectively described in detail below.

[0291] In S210, in some embodiments of the present application, the real-time temperature of the temperature sensor at the first moment may be obtained. The real-time temperature of the temperature sensor at the second moment may be obtained.

[0292] In some embodiments of the present application, the first moment and the second moment may be separated by a second set time period.

[0293] In some embodiments of the present application, the second set time length may be 5 minutes. The second set time length may be 3 minutes. This embodiment does not limit the specific value of the second set time length.

[0294] In S220 , in some embodiments of the present application, a difference between the real-time temperature of the temperature sensor at the first moment and the real-time temperature at the second moment may be calculated.

[0295] In some embodiments of the present application, the difference may be equal to the real-time temperature of the temperature sensor at the first moment minus the real-time temperature at the second moment.

[0296] In some embodiments of the present application, the difference may be equal to the real-time temperature of the temperature sensor at the second moment minus the real-time temperature of the temperature sensor at the first moment.

[0297] In some embodiments of the present application, the preset temperature change value may be 3 degrees Celsius. The preset temperature change value may be 5 degrees Celsius. This embodiment does not limit the specific value of the temperature change value.

[0298] In some embodiments of the present application, a difference between the real-time temperature of the temperature sensor at a first moment and the real-time temperature at a second moment may be calculated, and it may be determined whether the difference is below a preset temperature change value.

[0299] In S230 , if it is detected that the difference is below the temperature change value, indicating that the temperature sensor may be faulty, an alarm may be controlled to alert the user of the abnormal situation.

[0300] In some embodiments of the present application, the real-time temperature of the temperature sensor at a first moment and the real-time temperature at a second moment can be obtained, where the interval between the first moment and the second moment is 5 minutes. If the difference is detected to be below 3 degrees Celsius, it indicates that the temperature sensor may have failed at this time, and an alarm can be controlled to alert the user of the abnormal situation.

[0301] As can be seen from the above S210-S230, the real-time temperature of the temperature sensor at the first moment and the real-time temperature at the second moment are obtained, wherein the first moment and the second moment are separated by a second set time period, and it is determined whether the difference between the real-time temperature at the first moment and the real-time temperature at the second moment is below a preset temperature change value. If it is detected that the difference is below the temperature change value, it indicates that the temperature sensor may have failed at this time, and an alarm can be controlled to alert the user that an abnormal situation has occurred.

[0302] In some embodiments of the present application, the control unit may be configured to execute the following:

[0303] The water level of the condensed water is obtained, and the working states of the top water inlet valve, the first water inlet valve and the second water inlet valve are switched and controlled according to the water level.

[0304] Furthermore, in some embodiments of the present application, the water level of the condensed water can be obtained by a water level sensor.

[0305] In some embodiments of the present application, a pressure sensor may be provided at the bottom of the condensed water collection container, and the water level of the condensed water may be indirectly obtained through the pressure sensor.

[0306] In some embodiments of the present application, if it is detected that the water level of the condensed water is too high, the top water inlet valve, the first water inlet valve, and the second water inlet valve may be closed.

[0307] In some embodiments of the present application, if the condensed water level is detected to be high, the opening of at most one water inlet valve may be limited. If the condensed water level is detected to be high, the opening of only the top water inlet valve may be limited. If the condensed water level is detected to be high, the opening of only the first water inlet valve may be limited. If the condensed water level is detected to be high, the opening of only the second water inlet valve may be limited.

[0308] In some embodiments of the present application, if the condensed water level is detected to be low, opening of two water inlet valves may be limited to a maximum of two. If the condensed water level is detected to be low, opening of the top water inlet valve and the first water inlet valve may be limited to a maximum of two. If the condensed water level is detected to be low, opening of the top water inlet valve and the second water inlet valve may be limited to a maximum of two. If the condensed water level is detected to be low, opening of the first water inlet valve and the second water inlet valve may be limited to a maximum of two.

[0309] In some embodiments of the present application, if it is detected that the water level of the condensed water is too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be freely controlled to open.

[0310] From the above, it can be seen that the water level of the condensed water is obtained, and the working states of the top water inlet valve, the first water inlet valve and the second water inlet valve can be switched and controlled according to the water level, so as to avoid the water level of the condensed water being too high, but failing to close the water inlet valve in time, resulting in wetting the clothes in the inner drum.

[0311] In other embodiments of the present application, the control unit may be configured to execute the following:

[0312] The water level of the condensed water is obtained, and the working states of the first water inlet valve and the second water inlet valve are switched and controlled according to the water level.

[0313] Furthermore, in some embodiments of the present application, if the condensed water level is detected to be high, the opening of at most one water inlet valve may be limited. If the condensed water level is detected to be high, the opening of only the first water inlet valve may be limited. If the condensed water level is detected to be high, the opening of only the second water inlet valve may be limited.

[0314] In some embodiments of the present application, if it is detected that the water level of the condensed water is low, the first water inlet valve and the second water inlet valve can be freely controlled to open.

[0315] From the above, it can be seen that the water level of the condensed water is obtained, and the working states of the first water inlet valve and the second water inlet valve can be switched and controlled according to the water level, so as to avoid the water level of the condensed water being too high, but failing to close the water inlet valve in time, resulting in wetting the clothes in the inner drum.

[0316] Figure 22 This is a flowchart of steps that can be executed by the control unit of other embodiments of the present invention.

[0317] like Figure 22 As shown, in some embodiments of the present application, the control unit may be configured to execute the following S310-S350:

[0318] S310, obtaining the water level of condensed water.

[0319] S320: Determine whether the water level is above a first safety water level and below a maximum protection water level.

[0320] S330: If the answer is yes, the top water inlet valve is controlled to open.

[0321] S340: Determine whether the water level is above the maximum protection water level.

[0322] S350: If the answer is yes, the top water inlet valve, the first water inlet valve and the second water inlet valve are controlled to be closed.

[0323] The above S310-S350 are respectively described in detail below.

[0324] In S310 , in some embodiments of the present application, the water level of the condensed water may be acquired by a water level sensor.

[0325] In some embodiments of the present application, a pressure sensor may be provided at the bottom of the condensed water collection container, and the water level of the condensed water may be indirectly obtained through the pressure sensor.

[0326] In S320 - S330 , in some embodiments of the present application, if it is detected that the water level is above the first safe water level, it indicates that the current water level is relatively high.

[0327] In some embodiments of the present application, if the water level is detected to be below the highest protection water level, it indicates that the current water level is not too high.

[0328] In some embodiments of the present application, if it is detected that the water level reaches above the first safety water level and is below the maximum protection water level, indicating that the current water level is high but not too high, the opening of at most one water inlet valve can be limited to avoid the condensed water level being too high and wetting the clothes in the inner drum.

[0329] In some embodiments of the present application, in order to effectively condense the entire condensate pan and effectively reduce the temperature of the condensate pan, if it is detected that the water level reaches above the first safe water level and is below the highest protection water level, the top water inlet valve can be controlled to open.

[0330] In some embodiments of the present application, the first safe water level may be lower than the maximum protection water level. The first safe water level may be lower than the bottom height of the inner tube. The maximum protection water level may be lower than the bottom height of the inner tube.

[0331] In some embodiments of the present application, the first safe water level may be 7 cm below the bottom height of the inner tube. The first safe water level may be 6 cm below the bottom height of the inner tube. This embodiment does not limit the specific value of the first safe water level.

[0332] In some embodiments of the present application, the maximum protection water level may be 5 cm below the bottom height of the inner tube. The maximum protection water level may be 3 cm below the bottom height of the inner tube. This embodiment does not limit the specific value of the maximum protection water level.

[0333] From the above, it can be seen that if the water level is detected to be above the first safe water level and below the highest protection water level, the top water inlet valve can be controlled to open. On the one hand, it can prevent the condensed water level from being too high and wetting the clothes in the inner drum. On the other hand, by opening the top water inlet valve, the entire condensation tray can be effectively condensed, which can more effectively reduce the temperature of the condensation tray.

[0334] In S340-S350, if it is detected that the water level is above the maximum protection water level, it indicates that the current water level is too high.

[0335] From the above, it can be seen that if the water level is detected to be above the maximum protection water level, the top water inlet valve, the first water inlet valve and the second water inlet valve can be controlled to close, thereby effectively preventing the water level of the condensed water from further increasing and wetting the clothes in the inner drum.

[0336] Figure 23 This is a flowchart of steps that can be executed by the control unit of other embodiments of the present invention.

[0337] like Figure 23 As shown, in some embodiments of the present application, the control unit may be configured to execute the following S410-S450:

[0338] S410, obtaining the water level of condensed water.

[0339] S420: Determine whether the water level is above a second safe water level.

[0340] S430: If the answer is yes, drain the water to lower the water level to below the second safe water level.

[0341] S440: Acquire the real-time temperature of the temperature sensor.

[0342] S450: According to the real-time temperature of the temperature sensor, the working states of the top water inlet valve, the first water inlet valve, and the second water inlet valve are switched and controlled.

[0343] The above S410-S450 are respectively described in detail below.

[0344] In S410 , in some embodiments of the present application, the water level of the condensed water may be acquired by a water level sensor.

[0345] In some embodiments of the present application, a pressure sensor may be provided at the bottom of the condensed water collection container, and the water level of the condensed water may be indirectly obtained through the pressure sensor.

[0346] In S420-S430, in some embodiments of the present application, before the control unit executes switching control of the respective working states of the top water inlet valve, the first water inlet valve and the second water inlet valve according to the real-time temperature of the temperature sensor, the water level of the condensed water can be detected.

[0347] In some embodiments of the present application, if the water level is detected to be above the second safety water level, it indicates that the current water level is not low. In order to avoid the condensed water level being too high and wetting the clothes in the inner drum when controlling the opening of the water inlet valve, the condensed water can be controlled to be discharged.

[0348] In some embodiments of the present application, drainage may be controlled to drain the water level to below a second safe water level.

[0349] In some embodiments of the present application, the second safe water level is lower than the first safe water level.

[0350] In some embodiments of the present application, the second safety water level may be 10 cm below the bottom height of the inner tube. The second safety water level may be 8 cm below the bottom height of the inner tube. This embodiment does not limit the specific value of the second safety water level.

[0351] From the above, it can be seen that before the working states of the top water inlet valve, the first water inlet valve and the second water inlet valve are switched and controlled according to the real-time temperature of the temperature sensor, if it is detected that the water level reaches above the second safety water level, where the second safety water level is lower than the first safety water level, the drainage can be controlled to drain the water level to below the second safety water level, thereby avoiding the condensed water level being too high and wetting the clothes in the inner drum when the water inlet valve is controlled to be opened.

[0352] In S440 , the temperature sensor may be used to detect the temperature of the condensation pan. The real-time temperature of the temperature sensor may reflect the real-time temperature of the condensation pan.

[0353] In S450, when the water inlet valve is in the open state, the corresponding water inlet provides condensed water. When the water inlet valve is in the closed state, the corresponding water inlet stops providing condensed water.

[0354] In some embodiments of the present application, when the top water inlet valve is in an open state, the corresponding top water inlet provides condensed water. When the top water inlet valve is in a closed state, the corresponding top water inlet stops providing condensed water.

[0355] In some embodiments of the present application, when the first water inlet valve is in an open state, the corresponding first water inlet provides condensed water, and when the first water inlet valve is in a closed state, the corresponding first water inlet stops providing condensed water.

[0357] Figure 24 This is a flowchart of steps that can be executed by the control unit of other embodiments of the present invention.

[0358] like Figure 24 As shown, in some other embodiments of the present application, the control unit may be configured to execute the following S510-S590:

[0359] S510: Acquire the real-time temperature of the temperature sensor.

[0360] S520: Determine whether the real-time temperature of the temperature sensor is above a fourth set temperature.

[0361] S530: If the answer is yes, the first water inlet valve and the second water inlet valve are controlled to be opened.

[0362] S540: Determine whether the real-time temperature of the temperature sensor is within a temperature range between a fourth set temperature and a fifth set temperature.

[0363] S550: If the answer is yes, the first water inlet valve and the second water inlet valve are alternately opened according to the third set frequency control.

[0364] S560: Determine whether the real-time temperature of the temperature sensor is within a temperature range between a fifth set temperature and a sixth set temperature.

[0365] S570: If the answer is yes, the first water inlet valve and the second water inlet valve are alternately opened according to the fourth set frequency control.

[0366] S580: Determine whether the real-time temperature of the temperature sensor is below a sixth set temperature.

[0367] S590: If the answer is yes, the first water inlet valve and the second water inlet valve are controlled to be closed.

[0368] The above S510-S590 are respectively described in detail below.

[0369] In S510, the temperature sensor may be used to detect the temperature of the condensation pan. The real-time temperature of the temperature sensor may reflect the real-time temperature of the condensation pan.

[0370] In S520-S530, in some embodiments of the present application, if it is detected that the real-time temperature of the temperature sensor is above the fourth set temperature, indicating that the current temperature of the condensation tray is too high, the first water inlet valve and the second water inlet valve can be controlled to open.

[0371] In some embodiments of the present application, the fourth set temperature may be 40 degrees Celsius. The fourth set temperature may also be 50 degrees Celsius. This embodiment does not limit the specific value of the fourth set temperature.

[0372] In some embodiments of the present application, the temperature above the fourth set temperature can be used as the first temperature interval.

[0373] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be above 40 degrees Celsius, indicating that the current temperature of the condensation tray is too high, the first water inlet valve and the second water inlet valve may be controlled to open.

[0374] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be above the fourth set temperature, indicating that the current temperature of the condensation tray is too high, the first water inlet valve and the second water inlet valve can be controlled to open to effectively reduce the temperature of the condensation tray. By effectively reducing the temperature of the condensation tray, the heat exchange efficiency of the condensation tray can be improved, thereby improving the condensation efficiency of the condensation tray.

[0375] In S540-S550, in some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range between the fourth set temperature and the fifth set temperature, indicating that the current temperature of the condensation tray is high but not too high, the first water inlet valve and the second water inlet valve can be alternately opened according to the third set frequency control.

[0376] In some embodiments of the present application, the fifth set temperature is lower than the fourth set temperature.

[0377] In some embodiments of the present application, the temperature range between the fourth set temperature and the fifth set temperature can be used as the second temperature range.

[0378] In some embodiments of the present application, the fifth set temperature may be 30 degrees Celsius. The fifth set temperature may be 35 degrees Celsius. This embodiment does not limit the specific value of the fifth set temperature.

[0379] In some embodiments of the present application, the third set frequency may be 30 seconds. The third set frequency may be 35 seconds. This embodiment does not limit the specific value of the third set frequency.

[0380] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range of 30 degrees Celsius to 40 degrees Celsius, indicating that the current temperature of the condensation tray is high but not too high, the first water inlet valve and the second water inlet valve can be alternately opened at a frequency of 30 seconds.

[0381] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be in the temperature range between the fourth set temperature and the fifth set temperature, indicating that the current temperature of the condensation tray is high but not too high, the first water inlet valve and the second water inlet valve can be alternately opened according to the third set frequency control, thereby ensuring that the temperature of the condensation tray is effectively lowered while avoiding all water inlet valves being in the open state all the time and causing water waste.

[0382] In S560-S570, in some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range between the fifth set temperature and the sixth set temperature, indicating that the current temperature of the condensation pan is not high but not too low, the top water inlet valve, the first water inlet valve and the second water inlet valve can be alternately opened according to the fourth set frequency control.

[0383] In some embodiments of the present application, the sixth set temperature is lower than the fifth set temperature.

[0384] In some embodiments of the present application, the temperature range between the fifth set temperature and the sixth set temperature can serve as the third temperature range.

[0385] In some embodiments of the present application, the sixth set temperature may be 20 degrees Celsius. The sixth set temperature may be 25 degrees Celsius. This embodiment does not limit the specific value of the sixth set temperature.

[0386] In some embodiments of the present application, the fourth set frequency is greater than the third set frequency.

[0387] In some embodiments of the present application, the fourth set frequency may be 45 seconds. The fourth set frequency may be 50 seconds. This embodiment does not limit the specific value of the fourth set frequency.

[0388] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be in the temperature range of 20 degrees Celsius to 30 degrees Celsius, indicating that the current temperature of the condensation tray is not high but not too low, the first water inlet valve and the second water inlet valve can be alternately opened at a frequency of 45 seconds.

[0389] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be in the temperature range of the fifth set temperature and the sixth set temperature, indicating that the current temperature of the condensation tray is not high but not too low, the first water inlet valve and the second water inlet valve can be alternately opened according to the fourth set frequency control, thereby ensuring that the temperature of the condensation tray is effectively lowered while avoiding all water inlet valves being in the open state all the time and causing water waste.

[0390] In S580-S590, if it is detected that the real-time temperature of the temperature sensor is below the sixth set temperature, indicating that the current temperature of the condensation tray is too low, the first water inlet valve and the second water inlet valve may be controlled to be closed.

[0391] In some embodiments of the present application, the temperature below the sixth set temperature can be used as the fourth temperature interval.

[0392] In some embodiments of the present application, if the real-time temperature of the temperature sensor is detected to be below 20 degrees Celsius, indicating that the current temperature of the condensation tray is too low, the first water inlet valve and the second water inlet valve may be controlled to be closed.

[0393] From the above, it can be seen that if the real-time temperature of the temperature sensor is detected to be below the sixth set temperature, indicating that the current temperature of the condensation tray is too low, the first water inlet valve and the second water inlet valve can be controlled to be closed, thereby ensuring the condensation efficiency of the condensation tray while avoiding waste of water resources.

[0394] In other embodiments of the present application, the control unit may be configured to execute the following:

[0395] If the control simultaneously opens the first water inlet valve and the second water inlet valve for more than the third set time, and the temperature of the temperature sensor is still detected to be above the set temperature limit, the control will issue an alarm.

[0396] As can be seen from the above, in some embodiments of the present application, the third set time length can be 10 minutes. The third set time length can be 15 minutes. This embodiment does not limit the specific value of the third set time length.

[0397] In some embodiments of the present application, the set temperature limit value may be 50 degrees Celsius. The set temperature limit value may be 40 degrees Celsius. This embodiment does not limit the specific value of the set temperature limit value.

[0398] In some embodiments of the present application, if the first water inlet valve and the second water inlet valve are controlled to be opened simultaneously for more than 10 minutes, and the temperature of the temperature sensor is detected to be still above 50 degrees Celsius, indicating that the condensation water may be abnormally discharged at this time, an alarm can be controlled to remind the user that an abnormal situation has occurred.

[0399] From the above, it can be seen that if the first water inlet valve and the second water inlet valve are opened at the same time for more than the third set time, but the temperature of the condensation tray still reaches above the set temperature limit, it indicates that the condensation water may be abnormal at this time, and an alarm can be controlled to remind the user of the abnormal situation.

Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
