The effectiveness of clothing drying has become a major concern. Utility Model Content

[0003] In view of this, the present application aims to provide a clothing processing device that helps to improve the heat exchange efficiency of airflow and also helps to increase the airflow path, so that the heat exchange of airflow is more complete, thereby helping to improve the drying effect of clothing.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a garment processing device, comprising:

[0006] Box;

[0007] A cylindrical assembly is disposed inside the box, the cylindrical assembly having a clothing processing chamber, and an air inlet and an air outlet communicating with the clothing processing chamber;

[0008] A base is disposed above the cylindrical assembly. The base has an air duct, and a return air inlet and an air supply inlet connected to the air duct. The return air inlet is connected to the air outlet, and the air supply inlet is connected to the air inlet.

[0009] A heat exchange assembly is disposed within the air duct;

[0010] An impeller is disposed on the base and upstream of the heat exchange assembly along the airflow direction;

[0011] In a plane projection perpendicular to the height of the garment processing equipment, the projection of the impeller and the projection of the air outlet are respectively located in two areas diagonally arranged on the housing.

[0012] In some implementations, the return air inlet faces the bottom side of the base, and the impeller is located above the return air inlet.

[0013] In some implementations, the axis of rotation of the impeller is parallel to the height direction of the garment processing device.

[0014] In some implementations, the base includes a volute, the impeller is disposed inside the volute, and the return air inlet is disposed on the bottom wall of the volute.

[0015] In some implementations, the volute is provided with an outlet facing the windward side of the heat exchange assembly.

[0016] In some embodiments, the garment handling device includes a detergent dispenser arranged in a front-to-back direction with the impeller, and the impeller is located behind the detergent dispenser.

[0017] In some implementations, in a plane projection perpendicular to the height of the clothing processing device, the projected outline of the housing is divided into four regions by a first reference line and a second reference line. The detergent box, the impeller, and the air outlet are located in different regions. The first reference line is parallel to the front-back direction of the clothing processing device, the second reference line is parallel to the left-right direction of the clothing processing device, and the first reference line and the second reference line pass through the center of the housing.

[0018] In some embodiments, the heat exchange assembly includes a condensation dehumidification structure and a heating structure, the condensation dehumidification structure and the heating structure being arranged along the left-right direction of the clothing processing equipment, and the heating structure being located downstream of the condensation dehumidification structure along the airflow direction;

[0019] In a plane projection perpendicular to the height of the garment processing device, the heating structure and the impeller are located on opposite sides of a first reference line, wherein the first reference line is parallel to the front-back direction of the garment processing device and passes through the center of the housing.

[0020] In some embodiments, the heating structure includes a condenser arranged in the left-right direction of the garment processing equipment and an electric auxiliary heating device located downstream of the condenser in the direction of airflow.

[0021] In some embodiments, the condensation dehumidification structure includes an evaporator and a spray device, the spray device being used to supply liquid to the windward side of the evaporator or the evaporator, so that the liquid comes into contact with the airflow flowing through the air duct for heat exchange.

[0022] In some embodiments, the condensation dehumidification structure further includes a liquid cooling device for circulating coolant, the liquid cooling device being located upstream of the evaporator along the airflow direction, and the spray device being used to supply liquid toward the liquid cooling device.

[0023] The garment processing device provided in this application embodiment has an impeller located upstream of the heat exchange assembly along the airflow direction. During rotation, the impeller generates a significant negative pressure at the return air inlet. The hot, humid airflow from the garment processing chamber enters the air duct through the return air inlet, while a positive pressure is generated on the air inlet side of the impeller's heat exchange assembly. This provides a strong driving force for the airflow through the heat exchange assembly, ensuring sufficient speed and flow rate, thereby improving heat exchange efficiency and garment drying performance. Furthermore, because the impeller is located upstream of the heat exchange assembly, the heated airflow does not pass through it, which also aids in heat dissipation and extends the impeller's lifespan.

[0024] The clothing processing device provided in this application embodiment has the projection of the impeller and the projection of the air outlet located in two areas diagonally arranged in the housing, which makes the distance between the impeller and the air outlet greater, thereby helping to increase the flow path of the airflow, making the heat exchange of the airflow more complete, and helping to improve the heat exchange effect of the airflow, thereby improving the drying effect of the clothing.

It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0036] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0037] Please see Figure 1 and Figure 2 This application provides a garment processing device. The garment processing device includes a housing 10, a cylindrical assembly 20, a base 30, and a heat exchange assembly.

[0038] It is understandable that there are no restrictions on the type of garment processing equipment; for example, it can be a dryer, a washer-dryer combo, or a washer-dryer set. Garment processing equipment must at least be able to perform a drying function independently.

[0039] The cylindrical assembly 20 is housed within the housing 10. The housing 10 is used to house the cylindrical assembly 20.

[0040] The tube assembly 20 has a clothing handling chamber 21, and an air inlet 22 and an air outlet communicating with the clothing handling chamber 21. The clothing handling chamber 21 is used to hold clothing.

[0041] The location of the air inlet 22 is not limited. For example, the garment processing equipment includes a door seal ring 70, which is located at the front end of the drum assembly 20, and the air inlet 22 is located on the door seal ring 70. In some embodiments, the air inlet 22 is located on the upper part of the door seal ring 70. Here, the upper part of the door seal ring 70 refers to a part that is higher than the center of the door seal ring 70.

[0042] The location of the air outlet is not limited. For example, the air outlet can be located on the side wall of the cylindrical assembly 20 or on the rear wall of the cylindrical assembly 20.

[0043] The base 30 is located above the cylindrical assembly 20. The base 30 has an air duct 31, and a return air inlet 32 ​​and an air supply inlet 33 connected to the air duct 31. The return air inlet 32 ​​is connected to the air outlet, and the air supply inlet 33 is connected to the air inlet 22.

[0044] It is understandable that the return air inlet 32 ​​is connected to the air outlet. This connection can be either direct or separated. The return air inlet 32 ​​and the air outlet can be connected by a straight or curved pipe. No specific restrictions are imposed here, as long as the airflow can flow from the air outlet to the return air inlet 32.

[0045] The air outlet 33 is connected to the air inlet 22. This connection can be either direct or spaced out. The air outlet 33 and the air inlet 22 can be connected by a straight or curved pipe. No particular limitation is made here, as long as the airflow can flow from the air outlet 33 to the air inlet 22.

[0046] The heat exchange assembly is located inside the air duct 31. The heat exchange assembly is used to exchange heat with the airflow passing through the air duct 31, thereby achieving condensation, dehumidification, and heating of the airflow.

[0047] The drying principle of the clothing processing equipment provided in this application embodiment is as follows: the hot and humid airflow in the clothing processing chamber 21 flows from the air outlet to the air return port 32, and then enters the air duct 31. The heat exchange component in the air duct 31 first condenses and dehumidifies the hot and humid airflow, and then heats it. The heated dry hot airflow flows from the air supply port 33 to the air inlet 22, and then flows into the clothing processing chamber 21. When the dry hot airflow exchanges heat with the clothing, it becomes hot and humid airflow. The hot and humid airflow flows from the air outlet to the air return port 32 again. This cycle is repeated to achieve continuous drying of clothing.

[0048] In some embodiments, the garment processing device includes an impeller disposed on the base 30 and upstream of the heat exchange assembly along the airflow direction. During rotation, the impeller generates a significant negative pressure at the return air inlet 32, allowing the hot, humid airflow within the garment processing chamber 21 to enter the air duct 31 more quickly and in larger quantities from the return air inlet 32. Furthermore, the impeller generates positive pressure on the air inlet side of the heat exchange assembly, providing a strong driving force for the airflow through the heat exchange assembly. This ensures the speed and flow rate of the airflow through the heat exchange assembly, thereby improving the heat exchange efficiency and enhancing the garment drying effect. Additionally, because the impeller is located upstream of the heat exchange assembly, the hot airflow heated by the heat exchange assembly does not flow through the impeller, which also helps dissipate heat from the impeller and extends its service life.

[0049] Please see Figure 6 In a plane projection perpendicular to the height of the garment processing equipment, the projection of the impeller and the projection of the air outlet 33 are located in two diagonally opposite areas of the housing 10. That is, the diagonal arrangement of the impeller and air outlet 33 increases the distance between them, thus lengthening the airflow path and allowing for more thorough heat exchange, thereby improving the heat exchange effect and ultimately enhancing the garment drying performance.

[0050] It should be noted that you should refer to [link / reference]. Figure 6 In a plane projection perpendicular to the height of the garment processing equipment, the projected outline of the housing 10 is divided into four regions by the vertical first reference line L1 and the second reference line L2. These four regions can also be understood as the four quadrants of a Cartesian coordinate system in mathematics. The first reference line L1 is parallel to the front-back direction of the garment processing equipment, and the second reference line L2 is parallel to the left-right direction of the garment processing equipment. The first reference line L1 and the second reference line L2 pass through the center of the housing 10.

[0051] The box 10 includes a left side panel, a right side panel, a front panel, and a rear panel. The projected outline of the box 10 refers to the outline of the quadrilateral frame formed by the top edges of the left side panel, the right side panel, the front panel, and the rear panel.

[0052] Two regions arranged diagonally refer to two regions that are diagonally opposite each other among the four regions. For example, if the four quadrants are arranged clockwise as first quadrant 30a, second quadrant 30b, third quadrant 30c, and fourth quadrant 30d, the two regions arranged diagonally can be first quadrant 30a and third quadrant 30c, or second quadrant 30b and fourth quadrant 30d.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the front-to-back direction is indicated by d1, which includes both front-to-back and back-to-front directions; the left-to-right direction is indicated by d2, which includes both left-to-right and right-to-left directions. For example... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the height direction is the direction indicated by d3, which includes both the top-down direction and the bottom-up direction.

[0054] In some embodiments, the return air vent 32 faces the bottom side of the base 30, and the impeller is located above the return air vent 32.

[0055] It should be noted that "the impeller is located above the return air inlet 32" means that the impeller is positioned higher than the return air inlet 32, and the projection of the impeller onto the plane perpendicular to the height direction at least partially overlaps with the projection of the return air inlet 32.

[0056] In this embodiment, the impeller is located above the return air inlet 32, which makes the impeller located on the air outlet side of the return air inlet 32 ​​and helps to reduce the distance between the impeller and the return air inlet 32 ​​in the height direction. This helps to increase the negative pressure generated in the return air inlet 32 ​​during the rotation of the impeller, which is more conducive to the impeller drawing as much humid and hot air from the clothing processing chamber 21 into the air duct 31 as possible.

[0057] In some embodiments, the projection of the return air inlet 32 ​​onto a plane perpendicular to the height direction is within the projection range of the impeller. In this case, the impeller can generate good suction for the airflow at all points along the radial direction of the return air inlet 32, which facilitates the airflow from the return air inlet 32 ​​to enter the air duct 31 more and faster.

[0058] For example, the axis of rotation of the impeller is parallel to the height direction of the garment handling equipment. That is, the return air vent 32 is located on one side of the impeller's axial direction. This helps to reduce the size of the impeller in the height direction, thereby reducing the space occupied by the impeller on the base 30 in the height direction, and thus helping to reduce the size of the garment handling equipment in the height direction.

[0059] In the embodiment where the impeller is located above the return air inlet 32, the axis of rotation of the impeller is parallel to the height direction, which allows the impeller to draw in the airflow from the return air inlet 32 ​​more directly, thereby helping the impeller to draw more airflow into the air duct 31.

[0060] In some embodiments, the base 30 includes a volute 50, an impeller is disposed inside the volute, and a return air inlet 32 ​​is disposed on the bottom wall of the volute 50. This allows the impeller to be positioned above the return air inlet 32.

[0061] In this embodiment, the airflow in the clothing processing chamber 21 enters the volute 50 directly from the return air inlet 32, allowing the airflow from the return air inlet 32 ​​to enter the volute 50 more efficiently. Furthermore, the volute 50 defines a portion of the air duct 31.

[0062] In some embodiments, the volute 50 and the impeller form a centrifugal fan, meaning that the airflow enters the volute 50 from the axial side and exits from the radial side of the volute 50.

[0063] In some embodiments, the volute 50 is provided with an outlet 50a, which faces the windward side of the heat exchange assembly. This allows the impeller to blow airflow more directly onto the heat exchange assembly, helping to improve the heat exchange efficiency of the airflow.

[0064] The location of export 50a is not limited; for example, please refer to [link / reference]. Figure 4 The outlet 50a is located on the side wall of the volute 50.

[0065] For example, the volute 50 includes a body 51 and a cover 52, with the cover 52 located on the top side of the body 51.

[0066] For example, the shell 51 is cylindrical.

[0067] In some embodiments, the housing 51 and other structures of the surrounding base 30 are integral. This integral structure helps reduce the need for assembly between the housing 51 and other structures of the surrounding base 30.

[0068] In other embodiments, the shell 51 and other structures of the surrounding base 30 may also be separate structures. This facilitates the replacement of the volute 50.

[0069] In some embodiments, as shown in the figures, the garment handling apparatus includes a detergent dispenser 60. The detergent dispenser 60 is used to supply detergent to the garment handling chamber 21.

[0070] For example, the detergent dispenser 60 can be pulled out in the front-to-back direction, so that the user can add detergent into the detergent dispenser 60 when the detergent dispenser 60 is pulled out in the front-to-back direction.

[0071] The detergent dispenser 60 and the impeller are arranged in a front-to-back direction, with the impeller located behind the detergent dispenser 60. That is, the impeller is located in the space behind the detergent dispenser 60, which allows for a larger installation space for the impeller. This makes better use of the upper left space of the drum assembly 20, ensuring that the detergent dispenser 60 and the impeller have installation positions without reducing the volume of the drum assembly 20.

[0072] It should be noted that the space behind the detergent dispenser 60 refers to the space behind the detergent dispenser 60 when it is fully retracted.

[0073] In an embodiment where the impeller's rotation axis is parallel to the height direction of the garment handling equipment, the impeller is positioned on one side of the axial direction on the base 30, allowing for a larger radial dimension of the impeller. This helps to enhance the impeller's attraction to the airflow, thereby increasing the airflow velocity.

[0074] It is understood that the detergent box 60 can be located on the base 30, or on the left or right side plate of the housing 10, or connected to both the base 30 and the left side plate of the housing 10, or both the base 30 and the right side plate of the housing 10. There are no restrictions here, as long as the detergent box 60 and the impeller are arranged in the front-to-back direction.

[0075] For example, in an embodiment where the projected outline of the housing 10 is divided into four regions by a vertical first reference line L1 and a second reference line L2 in a plane projection perpendicular to the height direction, the detergent box 60, the impeller, and the air outlet 33 are located in different regions.

[0076] In this embodiment, see Figure 6 The first quadrant 30a and the second quadrant 30b are arranged in a front-back direction, with the first quadrant 30a located behind the second quadrant 30b. The third quadrant 30c and the fourth quadrant 30d are arranged in a front-back direction, with the fourth quadrant 30d located behind the third quadrant 30c.

[0077] This embodiment includes the following situations:

[0078] Type 1: The impeller is located in the first quadrant 30a, the air outlet 33 is located in the third quadrant 30c, and the detergent box 60 is located in the second quadrant 30b.

[0079] The second type: the impeller is located in the fourth quadrant 30d, the air outlet 33 is located in the second quadrant 30b, and the detergent box 60 is located in the third quadrant 30c.

[0080] In some embodiments, the heat exchange assembly includes a condensation and dehumidification structure and a heating structure, which are arranged along the left-right direction of the garment processing equipment. The heating structure is located downstream of the condensation and dehumidification structure along the airflow direction. That is, the impeller, condensation and dehumidification structure, and heating structure are arranged along the airflow direction. After the impeller blows the airflow towards the heat exchange assembly, the airflow first passes through the condensation and dehumidification structure to obtain a dry, cold airflow, and then passes through the heating structure to obtain a dry, hot airflow.

[0081] For example, in a plane projection perpendicular to the height of the garment processing equipment, the heating structure and the impeller are located on opposite sides of a first reference line. This helps to further increase the distance between the impeller and the heating structure, thereby further reducing the impact of the dry hot airflow heated by the heating structure on the impeller.

[0082] In some embodiments, the clothing processing equipment includes a heat pump system, which includes components such as a compressor, an evaporator 42, and a condenser 43, and the compressor, condenser 43, and evaporator 42 are connected in series in a refrigerant circuit.

[0083] The working principle of a heat pump system is as follows: The compressor draws in low-pressure gaseous refrigerant, compresses it, and discharges it as high-pressure gas. The discharged high-pressure gaseous refrigerant enters the condenser 43, where it is cooled by the ambient air around the condenser 43 and condenses into a high-pressure liquid (simultaneously transferring heat to the surrounding air). In other words, the air around the condenser 43 is heated. The high-pressure liquid refrigerant flows through a throttling device to reduce pressure, becoming a low-pressure, low-temperature gas-liquid two-phase mixture. This mixture enters the evaporator 42, where the liquid refrigerant evaporates and cools (simultaneously absorbing heat from the surrounding air). In other words, the air around the evaporator 42 is cooled. The refrigerant is then drawn back into the compressor and pressurized. This cycle repeats continuously, achieving heat exchange.

[0084] In this embodiment, the evaporator 42 can be a component of the above-mentioned condensation and dehumidification structure, and the condenser 43 can be a component of the above-mentioned heating structure.

[0085] For example, such as Figure 3 and Figure 4 As shown, the heating structure also includes an electric auxiliary heating device 44, which is arranged in the left-right direction with the condenser 43, and the electric auxiliary heating device 44 is located downstream of the condenser 43 in the direction of airflow.

[0086] In this embodiment, the hot and humid airflow in the clothing processing chamber 21 flows through the air outlet, passing through the impeller, the condensation and dehumidification structure, the condenser 43, and the electric auxiliary heating device 44, making the distance between the electric auxiliary heating device 44 and the impeller relatively large, thus reducing the impact of the airflow further heated by the electric auxiliary heating device 44 on the impeller.

[0087] In some embodiments, the condensation dehumidification structure includes a spray device for supplying liquid to the windward side of the evaporator 42 or to the evaporator 42, so that the liquid comes into contact with the airflow flowing through the air duct 31 for heat exchange. That is, the liquid sprayed by the spray device comes into direct contact with the airflow, which helps to cool the airflow and thus helps to condense and dehumidify the airflow.

[0088] In an embodiment where the spray device supplies liquid to the evaporator 42, the liquid sprayed by the spray device can also remove impurities such as lint adhering to the surface of the evaporator 42.

[0089] In some embodiments, the condensation dehumidification structure includes a liquid cooling device 41 for circulating coolant, the liquid cooling device 41 being located upstream of the evaporator 42 along the airflow direction.

[0090] In this embodiment, the airflow first undergoes a first condensation and dehumidification process via liquid cooling device 41, reducing the airflow's temperature and humidity. After the first condensation and dehumidification, the airflow then flows through evaporator 42 for a second condensation and dehumidification process, further reducing the airflow's temperature and humidity. Because the airflow has already undergone a first condensation and dehumidification process before flowing through evaporator 42, this helps to lower the evaporation temperature of evaporator 42 while ensuring the effectiveness of the airflow's condensation and dehumidification, thereby reducing the power consumption of the heat pump system.

[0091] It is understood that the condensation dehumidification structure may include both the spray device and the liquid cooling device 41, or it may only include one of the spray device and the liquid cooling device 41.

[0092] In embodiments where the condensation dehumidification structure includes both a spray device and a liquid cooling device 41, the spray device can also be used to supply liquid to the liquid cooling device 41, which not only helps to cool the airflow, but also removes impurities such as lint from the surface of the liquid cooling device 41.
