Description

Technical Field

[0001] The present invention relates to the technical field of washing equipment, and in particular to a drum washing machine with a heat pump drying function. Background Art

[0002] With the improvement of living standards, people are pursuing a safer and more comfortable clothes drying experience. However, the main drying methods of the mainstream clothes processing devices with independent drying functions or clothes processing devices with washing and drying functions on the market are electric heating. Electric heating drying has the problems of high power consumption and poor drying effect. Therefore, the mainstream market is gradually shifting from electric heating drying to research on heat pump drying.

[0003] Heat pump drying is not only energy-efficient but also does not damage clothes. However, there is still an unavoidable problem with the heat pump drying system, which is that the heat pump drying module will inevitably lead to a larger size of the entire machine. The size specifications of the entire machine are different from those of conventional washing machines, which will make the placement and space of commonly used clothing processing devices in the home unable to be universal. This is a common headache for consumers today.

[0004] Therefore, the present invention aims to solve the following technical problems existing in the existing clothes processing device with heat pump drying function:

[0005] 1. The height of a clothes processing device with a heat pump drying function is generally higher than that of a conventional clothes processing device, and the height cannot be effectively lowered.

[0006] 2. The internal space utilization rate of the clothes processing device is low.

[0007] 3. Large wind resistance during the drying process affects drying efficiency.

[0008] 4. It is difficult for the drying fan on a traditional washing machine to ensure the air tightness of the matching structure in the drying duct.

[0009] 5. The drying fan on a traditional washing machine is at risk of loosening or falling off when it is fixed to the entire machine cabinet.

[0010] 6. The drying fan on a traditional washing machine is easily affected by the vibration of the washing drum, making it difficult to ensure drying efficiency.

[0064] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0065] The terms used in the embodiments of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The singular forms "a," "the," and "the" used in the embodiments of the present invention and the appended claims are also intended to include plural forms, unless the context clearly indicates otherwise. "A plurality" generally includes at least two, but does not exclude the inclusion of at least one.

[0066] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0067] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0068] To further illustrate the technical solution of the present invention, Figure 1-Figure 25 , the following specific embodiments are provided.

[0069] See also Figure 1 and Figure 2 As shown, this embodiment provides a drum washing machine with a heat pump drying function, including a shell 1, in which a coaxially mounted inner drum 3 and an outer drum 2 are arranged, and the outer drum 2 is installed in the shell 1 through a vibration reduction module; the inner drum 3 is driven by a driving motor and is rotatably arranged in the outer drum 2.

[0070] During the washing process of the drum washing machine, washing water enters the outer drum 2 through the water inlet pipe. When the water level is reached, the water supply stops. The inner drum 3 is driven by the driving motor to rotate in the outer drum 2. During the rotation of the inner drum 2, the clothes are washed by lifting and beating.

[0071] like Figure 1 As shown, the drum washing machine is placed vertically on a horizontal ground, and a panel assembly 8 is provided in front of the housing 1 of the drum washing machine. A feeding port is provided on the panel assembly 8, and a door assembly 9 is installed on the feeding port of the panel assembly 8 for opening / closing the feeding port. Figure 1 The direction identification in the figure provides examples for the direction limitations of up, down, front, back, left and right in the present invention, so as to better explain the technical solution of the present invention.

[0072] Furthermore, the drum washing machine of this embodiment has a drying function, and this is a heat pump drying method achieved by a heat pump system. Existing drum washing machines generally require sufficient space to install the heat pump system in the housing to address the problem of heat pump efficiency, which results in an increase in the housing of the washing machine.

[0073] Therefore, the present invention proposes a drum washing machine with a heat pump drying function. The heat pump system includes an evaporator, a condenser, a compressor, and a fan assembly. The fan assembly transports the hot and humid drying air in the outer drum to the evaporator. The evaporator exchanges heat with the hot and humid drying air, condensing the moisture in the hot and humid drying air into dry and cold drying air. The dry and cold drying air is then transported to the condenser for heat exchange and heating, turning it into dry and hot drying air. The dry and hot drying air is then introduced into the outer drum to dry clothes, turning it into hot and humid drying air again, and the cycle continues. The refrigerant, serving as the working medium of the heat pump system, circulates between the condenser, the throttling device, the evaporator, and the compressor. The refrigerant absorbs heat in the evaporator to cool and dehumidify the hot and humid drying air drawn from the outer drum, and releases heat in the condenser to heat the dry and cold drying air drawn from the evaporator.

[0074] The present invention aims to propose a drum washing machine with a heat pump drying function. Taking into account the internal space layout of the drum washing machine shell, the internal space of the shell is fully utilized to realize the setting of the heat pump system, ensure the drying efficiency and drying effect, and keep the shell of the drum washing machine with the heat pump drying function the same size as the shell of an ordinary drum washing machine of the corresponding kilogram class.

[0075] Example 1

[0076] This embodiment designs and arranges the structure of the evaporator and condenser so as to ensure that the evaporator and condenser can be installed in the space inside the shell, thereby improving the space utilization inside the shell and effectively controlling the height of the whole machine. The specific technical solution is as follows:

[0077] See also Figures 1-9 As shown, a clothes processing device with a heat pump drying function in this embodiment includes:

[0078] A housing 1 forming an interior space;

[0079] The outer cylinder 2 is arranged in the inner space of the shell 1;

[0080] The heat pump module includes two device components, which include an evaporator 441 and a condenser 442. The evaporator 441 and / or the condenser 442 are arranged in the upper left space or the upper right space of the inner and outer cylinders 2 of the shell 1. The heat exchange body of the evaporator 441 and / or the condenser 442 has an external contour adapted to the upper left space or the upper right space in which it is located.

[0081] This embodiment addresses the structural characteristics of the upper left or upper right space within the housing of a laundry treatment device. Specifically, for drum washing machines, a detergent dispenser is typically located in the upper left space, while the upper right space, opposite the upper left space, has some free space. Therefore, in this embodiment, the laundry treatment device disposes the two device assemblies in the upper left or upper right space between the inner and outer drums 2 of the housing 1, taking into account the characteristics of the internal space. Furthermore, due to the limited upper left or upper right space between the inner and outer drums 2 of the housing 1, and to maintain the overall height of the laundry treatment device, the heat exchange bodies of the two device assemblies need to be as large as possible to maximize heat exchange efficiency and ensure drying results. Therefore, the heat exchange bodies of the evaporator 441 and / or condenser 442 of this embodiment have an outer contour adapted to the upper left or upper right space in which they are located. Specifically, the heat exchange bodies of the evaporator 441 and / or condenser 442 of this embodiment have an outer contour adapted to the upper left or upper right space in which they are located, meaning that the heat exchange bodies are arranged irregularly, adapting to the installation space to ensure drying efficiency.

[0082] As an optional embodiment of this embodiment, the heat exchange body of the evaporator 441 and / or condenser 442 described in this embodiment has a cross-section perpendicular to the axis of the outer cylinder that is wide at the top and narrow at the bottom. This is because the outer cylinder 2 is cylindrical and the shell 1 is a rectangular parallelepiped. The upper left or upper right space between the shell 1 and the outer cylinder 2 is wide at the top and narrow at the bottom. To fully utilize the space, the heat exchange body of the evaporator 441 and / or condenser 442 is adapted to have a wide top and narrow bottom shape.

[0083] As an optional implementation of this embodiment, the cross-section is approximately in the shape of a stepped surface or an approximately inverted L shape. In this way, not only can the installation space in the shell 1 be fully utilized, but also the processing and manufacturing of the evaporator 441 and / or condenser 442 is facilitated.

[0084] In this embodiment, the evaporator 441 and condenser 442 are disposed in the upper left or upper right space of the inner and outer tubs 2 of the housing 1, taking into account the spatial layout within the housing 1. This is primarily due to considerations regarding the placement of structural components within the housing 1. Specifically, a detergent dispenser is typically disposed in the upper left space of the inner and outer tubs 2 of the housing 1 of existing laundry processing devices. Therefore, the evaporator 441 and condenser 442 can be disposed in the upper right space of the inner and outer tubs 2 of the housing 1. If the detergent dispenser is disposed in the upper right space of the inner and outer tubs 2 of the housing 1, the evaporator 441 and condenser 442 can be disposed in the upper left space of the inner and outer tubs 2 of the housing 1.

[0085] The evaporator 441 and condenser 442 of this embodiment are arranged in a limited space inside the shell 1. In order to ensure the drying efficiency and drying effect of the evaporator 441 and condenser 442, the existing regular rectangular or square evaporator 441 and condenser 442 are not suitable for fully utilizing the space inside the shell 1 and cannot meet the drying efficiency.

[0086] Therefore, the shape of the heat exchange body of the evaporator 441 and / or condenser 442 of this embodiment is adapted to the space between the shell 1 and the outer cylinder 2, that is, the overall structure of the evaporator 441 and / or condenser 442 is adaptively designed according to the installation space and is no longer a regular rectangle, which can not only make full use of the installation space in the shell, but also ensure the heat exchange efficiency.

[0087] As an optional embodiment of this embodiment, the heat exchange body of the evaporator 441 and / or condenser 442 described in this embodiment has a first horizontal side adjacent to the top wall of the shell 1 and a second horizontal side distal to the top wall of the shell 1, as well as a first vertical side adjacent to the side wall of the shell 1 and a second vertical side distal to the side wall of the shell 1. The length of the second horizontal side is greater than the length of the first horizontal side, and the height of the first vertical side is greater than the height of the second vertical side. Due to the cylindrical structure of the outer cylinder 2 and the planar structure of the shell, the horizontal length of the space between the upper left or upper right portion of the inner and outer cylinders 2 of the shell 1 gradually decreases from top to bottom in the vertical direction. Therefore, in order to adapt to the installation space, the heat exchange body of the evaporator 441 and / or condenser 442 of this embodiment has a horizontal distance adjacent to the first horizontal side of the outer cylinder 2 that is shorter than the horizontal distance distal to the second horizontal side of the outer cylinder 2.

[0088] In order to facilitate the assembly of the condenser and the evaporator, as an optional embodiment of this embodiment, see Figure 5As shown, the condenser 442 and evaporator 441 described in this embodiment are integrated into a two-element module 44. The heat exchange body of the condenser 442 and the evaporator 441 includes a first heat exchange portion 4421 and a second heat exchange portion 4421, each having different horizontal lengths. This allows the heat exchange body of the two-element module 44 to present a stepped surface, with the horizontal length away from the outer cylinder being greater than the horizontal length near the outer cylinder. To better utilize this space, the cross-section of the heat exchange body of the two-element module 44 is configured to have a non-rectangular structure. That is, within the space, the cross-section of the heat exchange body of the two-element module 44 is configured to have an "L" shape, a "7" shape, or the like, and is placed within the space to maximize the cross-sectional area of ​​the heat exchange body of the two-element module 44, thereby enhancing the heat pump drying effect.

[0089] See also Figure 5 As shown, as an optional implementation scheme of this embodiment, the evaporator 441 and the condenser 442 both have a first heat exchange part 4451 away from the outer tube 2 and a second heat exchange part 4452 close to the outer tube 2. The first heat exchange part 4451 is formed by a first heat exchange tube 4453 of a first length inserted in the first fin, and the second heat exchange part 4452 is formed by a second heat exchange tube 4455 of a second length inserted in the second fin. The length of the first heat exchange tube 4453 is greater than the length of the second heat exchange tube 4455.

[0090] The first heat exchange part 4453 and the second heat exchange part 4455 described in this embodiment are connected through the third heat exchange tube 4454. The third heat exchange tube 4454 includes a first tube segment inserted in the first fin and having the same length as the first heat exchange tube 4453, a second tube segment inserted in the second fin and having the same length as the second heat exchange tube 4455, and a third tube segment connecting the first tube segment and the second tube segment.

[0091] The two-device module 44 of this embodiment includes a condenser 441 and an evaporator 442, both of which are obtained by inserting copper tubes through fins, and are used to generate heat and absorb heat respectively; and the space enclosed by the outer tube 2 and the shell 1 is used to maximize the cross-sectional area of ​​the heat exchange body of the two-device module 44 and place it in the said space; the heat exchange body of the evaporator 441 and the condenser 442 is stepped, and the copper tube flow path is inserted in the fins. The stepped cross section is connected by a long and short U-shaped third heat exchange tube 4454, so that the copper tube flow path of the stepped surface is connected, and the evaporator 441 and the condenser 442 are integrated in structure and easy to assemble; at the same time, the copper tube flow path is penetrated as a single inlet and a single outlet, thereby improving the utilization rate of the heat pump refrigerant medium.

[0092] Furthermore, the two-device assembly described in this embodiment includes a two-device box, and the two-device module 44 is disposed within the two-device box; the two-device box is fixed to the shell 1 and located at the upper left or upper right of the outer tube 2, with a gap between the two-device box and the outer tube peripheral wall of the outer tube 2. The two-device box of this embodiment includes a two-device box body 443 and a two-device box cover 444. The two-device box body 443 has an internal accommodating cavity with one end open. The two-device box cover 444 seals the open end of the two-device box body 443 to form a closed space. The two-device module 44 is placed within the internal closed space of the two-device box, similarly utilizing the space between the outer tube 2 and the shell 1, which is referred to as the effective space, and a certain safety gap is reserved between the outer tube 2 and the shell 1.

[0093] As an optional embodiment of this embodiment, the outer wall surface of the two container boxes opposite the outer cylinder wall is formed as an inwardly concave arc surface 4434. The inwardly concave arc surface 4434 and the outer cylinder wall are coaxial, and there is a gap between the inwardly concave arc surface 4434 and the outer cylinder wall. This can maximize the internal space of the two container boxes while maintaining a safe distance between the two container boxes and the outer cylinder 2.

[0094] Specifically, the two-device box in this embodiment has a first chamber for the side near the shell body 1 and a second chamber for the side near the outer tube 2, and the length of the first chamber in the horizontal direction is greater than the length of the second chamber in the horizontal direction; the first heat exchange part 4451 is arranged in the first chamber, and the second heat exchange part 4452 is arranged in the second chamber.

[0095] In this embodiment of a clothes processing device with a heat pump drying function, the outer wall of the outer tub 2 is suspended within the housing 1 via a vibration-damping hanging spring 53. A concave avoidance structure 4435 is provided on the side walls of the two container boxes opposite the vibration-damping hanging spring 53 to provide clearance for the installation of the vibration-damping hanging spring 53. Specifically, the concave avoidance structure 4435 is formed by partially inwardly recessing the side walls of the two container boxes opposite the vibration-damping hanging spring 53 to form a concave structure.

[0096] The present embodiment provides a clothing processing device with a heat pump drying function, wherein the heat pump module includes a fan assembly 43, which is fixed to the housing 1 and located at the upper left or upper right of the outer tube. A gap is formed between the fan assembly 43 and the outer tube peripheral wall of the outer tube 2. The two-device assembly is arranged on the side near the tube opening of the outer tube 2, and the fan assembly 43 is arranged on the side near the tube bottom of the outer tube 2. An air outlet 22 is provided at the top of the outer tube peripheral wall, and the fan assembly 43 is connected to the air outlet 22 via an air outlet duct 41. The two-device box has two-device box air inlets, and the fan outlet of the fan assembly 43 is directly connected to the two-device box air inlets. A door seal 24 is installed at the tube opening of the outer tube 2, and the two-device box has two-device box air outlets, which are connected to the door seal 24 via an air inlet duct 511.

[0097] As an optional embodiment of this embodiment, a clothes processing device with a heat pump drying function is provided with an outer drum avoidance area 231 on the outer drum circumferential wall of the outer drum 2, at a position opposite the two container boxes, for accommodating the installation of the two container boxes. Specifically, the outer drum avoidance area 231 is formed by reducing the height of, or removing, the reinforcing ribs on the outer drum 2 circumferential wall at a position opposite the two container boxes, thereby reducing the installation height of the two container boxes.

[0098] Example 2

[0099] This embodiment provides a specific structural design for the two-device box in the first embodiment, so as to realize the installation of the two-device components and optimize the circulation of the drying airflow.

[0100] See also Figure 1-Figure 3 、 Figure 10-13 As shown, a drum washing machine with a heat pump drying function in this embodiment includes:

[0101] outer cylinder 2;

[0102] The shell 1, the outer cylinder 2 is arranged in the inner space of the shell 1;

[0103] And a heat pump module, including two-device boxes and a two-device module 445 arranged in the two-device box 447, which is integrated with a condenser 442 and an evaporator 441. The two-device box 447 has a two-device box air inlet 4431, and the two-device box air inlet 4431 is inclined relative to the horizontal direction.

[0104] Specifically, the air inlet 4431 forms an acute angle with the horizontal direction; the air inlet 4431 of the two device boxes is preferably in an approximately rectangular shape with two upper and lower long sides and two left and right short sides.

[0105] The inclination direction of the air inlets 4431 of the two device boxes is inclined toward the direction of the line between the two points on the windward heat exchange surface close to the two device modules 445 that are farthest apart, or the inclination direction of the air inlets 4431 of the two device boxes is consistent with the direction of the line between the two points on the upper diagonal line of the windward heat exchange surface of the two device modules 445 that are farthest apart.

[0106] In this embodiment, the inclination direction of the air inlet 4431 of the two-device box is inclined toward the direction of the line between the two points on the windward heat exchange surface closest to the two-device module 445, or the inclination direction of the air inlet 4431 of the two-device box is consistent with the direction of the line between the two points on the upper diagonal of the windward heat exchange surface of the two-device module 445 that are farthest apart. In this way, the consistency of the flow direction of the moist and hot drying airflow toward the windward heat exchange surface of the two-device module 445 is ensured, and the drying airflow flowing from the air inlet 4431 of the two-device box toward the windward heat exchange surface of the two-device module 445 is avoided, thereby improving the drying heat exchange efficiency.

[0107] Furthermore, the two-device box 447 described in this embodiment includes side walls and a bottom wall, which enclose an open space for accommodating the two-device modules. The bottom wall is spaced apart from and opposite the outer cylinder 2. The two-device box air inlet 4431 is located on the side walls facing the drying airflow and close to the bottom wall. This embodiment utilizes the principle that hot air rises, and the two-device box air inlet 4431 is located at the bottom of the two-device box, allowing the hot and humid drying airflow to rise and more fully contact the two-device module 445, thereby improving drying efficiency.

[0108] Specifically, the two-container box described in this embodiment includes a first box side wall facing the drying airflow and a second box side wall opposite to the first box side wall, and the box bottom wall is a concave arc surface concave toward the internal accommodating space of the two-container box; the two-container box air inlet 4431 is opened on the first box side wall and close to the box bottom wall, and the two-container box also has two-container box air outlets opened on the second box side wall.

[0109] As an optional implementation scheme of this embodiment, the two-device module 445 has a first heat exchange part 4451 close to the shell side in the vertical direction and a second heat exchange part 4452 close to the outer tube side. The first heat exchange part 4451 is formed by a first heat exchange tube 4453 of a first length inserted in the first fin, and the second heat exchange part 4452 is formed by a second heat exchange tube 4455 of a second length inserted in the second fin. The length of the first heat exchange tube 4453 is greater than the length of the second heat exchange tube 4455; the projection of the two-device box air inlet 4431 along the central axis of the outer tube 2 on the projection plane perpendicular to the central axis obliquely crosses the diagonal of the two-device module 445 along the central axis of the outer tube 2 on the projection plane perpendicular to the central axis.

[0110] As an optional implementation of this embodiment, the air inlet 4431 of the two-dishbox box directly faces the evaporator heat exchange surface of the two-dishbox module 445, and there is a spacing between the air inlet 4431 and the evaporator heat exchange surface, and the spacing ranges from 20mm to 80mm. The two-dishbox module 445 and the air inlet 4431 of the two-dishbox box are arranged at a certain distance from each other to reduce wind resistance, ensure smooth flow of drying air, and reduce the load on the fan assembly.

[0111] As an optional embodiment of this embodiment, the first heat exchange section 4451 and the second heat exchange section 4452 each comprise a heat exchange body and a heat exchange pipe joint at one end of the heat exchange body. A wind deflector 4433 is provided within the two-device box, located on one side of the two-device box air inlet 4431, for directing the drying airflow to the heat exchange surface body. When an avoidance design is employed, the two devices also require a corresponding avoidance structure. With pipes on both sides of the two devices, an L-shape is the optimal solution, both avoiding the two-device box and providing space for the condenser pipe. However, the L-shaped two-device module has a gap, requiring the two-device box to serve as a windshield to ensure that the wind can fully pass through the two devices. The wind deflector 4433 of this embodiment is the same L-shaped plate as the L-shaped two-device module, which can better guide the drying airflow entering the two-device box air inlet 4431 to the windward heat exchange surface of the two-device module, blocking the drying airflow from reaching the heat exchange pipe joint. The wind resistance of the drying airflow at the heat exchange joint is relatively low, resulting in poor heat exchange efficiency.

[0112] At the same time, the heat pump module described in this embodiment includes a compressor mounted on a housing behind the outer cylinder. The compressor is connected to the two-element module 445 via a heat pump medium pipeline. A pipeline passage is formed between the air deflector 4433 and the two-element box body 443. The heat pump medium pipeline passes through the pipeline passage and connects to the heat exchange pipe joint. The air deflector 4433 of this embodiment also serves to construct a pipeline passage for arranging and connecting the heat pump medium pipeline between the compressor and the two-element module.

[0113] See also Figure 12As shown, in order to realize the installation of the two-device module 445, the two-device box body 443 of this embodiment has the following specific structure: a first support plate 4434 for supporting the first heat exchange part 4451 of the evaporator 441 and a second support plate 4437 for supporting the second heat exchange part 4452 of the evaporator 441 are provided on the inner wall surface of the bottom wall of the box, a third support plate 44314 for supporting the first heat exchange part 4451 of the condenser 442 and a fourth support plate 44310 for supporting the second heat exchange part 4452 of the condenser 442, and a separation card plate for separating the evaporator 441 and the condenser 442, the first support plate 4434 and the second support plate 4437 are located on one side of the separation card plate, and the third support plate 44314 and the fourth support plate 44310 are located on the other side of the separation card plate. The first support plate 4434 and the second support plate 4437 of this embodiment realize the support installation of the evaporator 441, the third support plate 44314 and the fourth support plate 44310 realize the support installation of the condenser 442, and the separation card plate is inserted between the evaporator 441 and the condenser 442 by snapping, while separating the integrated evaporator 441 and condenser 442.

[0114] Optionally, a stepped support platform 4436 is further provided on the inner wall surface of the bottom wall of the box, and the partition card includes a first partition card 4435 and a second partition card 4439 provided on the stepped support platform 4436, and the first heat exchange part 4451 and the second heat exchange part 4452 of the evaporator 441 and the condenser 442 close to each other are respectively abutted on the stepped support platform 4436, and the first partition card 4435 is inserted and clamped between the first heat exchange part of the evaporator 441 and the first heat exchange part of the condenser 442, and the second partition card 4439 is inserted and clamped between the second heat exchange part of the evaporator 441 and the second heat exchange part of the condenser 442.

[0115] In addition, the inner circumferential wall of the two-device box body 443 of this embodiment is provided with two-device corner limit blocks 44311 for circumferentially limiting the installation of the two-device modules. The two-device corner limit blocks 44311 abut against the corners of the two-device modules for circumferential limitation to prevent circumferential shaking.

[0116] In this embodiment, two-device box studs 44312 are further provided on the two-device box body 443 to achieve fixed connection and assembly with the two-device box cover 444.

[0117] As an optional embodiment of this embodiment, the bottom wall of the two-container box 447 is provided with a condensed water drain connector 44313 for draining condensed water. The water outlet direction of the condensed water drain connector 44313 is consistent with the flow direction of the drying air within the two-container box 447. In this way, the condensed water can be drained away with the help of the drying air force, avoiding the problem of condensed water accumulation and reduced drying efficiency.

[0118] Furthermore, a support plate for supporting the two-device module 445 is provided on the bottom inner wall of the two-device box 447, and the end of the support plate close to the condensate drain joint 44313 has a condensate guide arc surface 4438 bent toward the condensate drain joint, so that the condensate of the two-device module 445 can be drained to the condensate drain joint 44313.

[0119] The structural design of the two-device box 447 of this embodiment has the following beneficial effects:

[0120] 1. Using the principle of hot air rising, the air inlet of the two-device box is set at the bottom of the two-device box body to make the hot and humid drying air flow rise and contact the two-device module more fully, thereby improving the drying efficiency.

[0121] 2. In the projection direction of the front of the whole machine, the tilted air inlet is set diagonally across the two modules to ensure the consistency of the flow direction of the hot and humid drying air flow and avoid cross-flow.

[0122] 3. The two modules are set at a certain distance from the air inlets of the two devices to reduce wind resistance, ensure smooth flow of drying air, and reduce fan load.

[0123] 4. The water outlet direction of the condensate drain joint is consistent with the flow direction of the drying airflow, which can use the wind force to discharge the condensate to avoid the accumulation of condensate and the reduction of drying efficiency.

[0124] Example 3

[0125] This embodiment specifically optimizes the assembly and structural improvement of the fan assembly of the heat pump module, making better use of the space inside the housing for assembly, improving the space utilization rate inside the housing, ensuring drying efficiency, and simplifying the installation process. The specific solution is as follows:

[0126] See also Figure 1-Figure 3 、 Figures 14-18 As shown, this embodiment provides a drum washing machine with a heat pump drying function, comprising:

[0127] The outer cylinder 2 has an outer cylinder air outlet 22 at the top;

[0128] The shell 1, the outer cylinder 2 is arranged in the inner space of the shell 1;

[0129] And a heat pump module, including an evaporator, a condenser, a heat exchange air duct and a fan assembly 43 arranged in the space above the outer cylinder 2 and between the shell 1. The evaporator and condenser are arranged in the heat exchange air duct, and the fan air inlet of the fan assembly 43 is connected to the outer cylinder air outlet 22 on the outer cylinder 2. The fan air outlet of the fan assembly 43 is directly fixedly connected to the air duct inlet of the heat exchange air duct to form an integrated connection structure. The air duct outlet of the heat exchange air duct is connected to the inside of the outer cylinder 2.

[0130] The heat pump module described in this embodiment is composed of two-device components, a heat exchange air duct, a fan component and an air guide component; the two-device components include a condenser and an evaporator, which are used to generate heat and absorb heat respectively, both of which are obtained by copper tubes inserted through fins; and the two-device components are connected to the compressor through copper tubes to form a complete two-device flow path.

[0131] The heat exchange duct assembly is provided with supporting ribs for placing the two device assemblies, and the two device assemblies are completely placed in the heat exchange duct assembly, while ensuring that the ventilation area is not affected, and the movement of the two device assemblies is limited by the surrounding ribs and sponge strips, so that the freedom of the two device assemblies is completely restricted; at the same time, the heat exchange duct assembly is connected to the air guide assembly 446 and the fan assembly 43, and through the connecting outer cylinder, a complete heat pump drying circulation air path is formed; at the same time, the heat exchange duct serves as a channel for air circulation.

[0132] The two-device components are located between the outer cylinder and the shell. The outer cylinder is a cylindrical structure, and the shell is a flat structure. The spatial structure in which the two-device components are placed is a space composed of an arc surface and a flat surface. On the premise of ensuring the height of the entire machine, the two-device components are arranged to the maximum extent based on this space to enhance the heat pump drying effect.

[0133] At the same time, a safety gap is left between the heat exchange duct assembly and the outer cylinder, and the two components are set to the maximum extent within the effective space between the outer cylinder and the shell to increase the heat exchange area of ​​the fins and improve the drying efficiency.

[0134] Accordingly, the evaporator of the two-device assembly is located after the fan assembly. The fan assembly can blow the hot and humid air in the outer cylinder into the evaporator and condenser. After passing through the evaporator, the water in the air is condensed and flows along the fins to the bottom of the heat exchange air duct under the action of gravity. The condensed water is discharged through the ribs provided at the bottom of the heat exchange air duct. When passing through the condenser, the condenser generates heat, so that the cold and dry air flowing through the condenser is converted into hot and dry air, and then re-enters the outer cylinder through the first connecting member.

[0135] The heat pump module is attached to the shell, and the heat pump module is fixed on the shell so as to be unaffected by the vibration of the outer cylinder.

[0136] In this embodiment, the fan assembly 43 is fixedly connected to the heat exchange duct, which houses the evaporator and condenser, to form an integrated structure. When the evaporator, condenser, and fan assembly are assembled into an integrated module and installed within the housing 1, the cumbersome assembly and high assembly precision required by separately installing the evaporator, condenser, heat exchange duct, and fan assembly 43 within the housing are avoided. Furthermore, the integrated module installation reduces the internal installation space required for the housing 1, improving the internal space utilization of the housing 1 and reducing the overall height of the washing machine.

[0137] See also Figure 15 As shown, the periphery of the fan outlet described in this embodiment is provided with a first snap structure 431 and a first assembly hole 432, and the periphery of the air duct inlet of the heat exchange air duct is provided with a second slot structure 44315 and a second assembly hole 44316. The fan outlet and the air duct inlet are pre-fixed by snapping the first snap structure 431 and the second slot structure 44315 together, and then the fan outlet and the air duct inlet are fixedly connected by a connecting piece passing through the first assembly hole 432 and fastened to the second assembly hole 44316, so that the evaporator, condenser, heat exchange air duct and fan assembly are assembled into an integrated module.

[0138] In this embodiment, the buckle structure is designed by combining buckles and screws to facilitate pre-fixation during assembly, and then fastening is performed by screws.

[0139] Furthermore, in order to improve the sealing of the connection between the fan outlet and the air duct inlet and prevent air leakage, a sealing ring 46 is provided between the fan outlet and the air duct inlet in this embodiment, and an annular sealing groove for assembling the sealing ring is provided in the fan outlet and / or the air duct inlet.

[0140] As an optional implementation of this embodiment, this embodiment is to solve the problem of fixed installation of the fan assembly 43 in the housing. Figure 15 、 16 As shown in Figure 18, the fan assembly includes a volute, a fan impeller 4310 and a fan motor 438, the fan impeller 4310 is arranged in the volute, the fan motor 438 is arranged on the volute, the motor shaft of the fan motor 4310 extends into the volute to connect the fan impeller 4310, the fan air inlet is arranged on the volute, the fan air inlet and the fan impeller share a central axis, the fan air outlet is arranged on the volute, and the central axis of the fan air outlet is perpendicular to the central axis of the fan impeller; the volute is fixedly mounted on the shell 1, and the central axis of the fan air inlet on the volute and the fan assembly are eccentrically arranged relative to the central axis of the air outlet on the outer cylinder. The eccentric arrangement is to move the installation position of the fan assembly 43 in the shell 1 backward, leaving more installation space for the arrangement of the two boxes, saving the overall height.

[0141] Furthermore, since a detergent dispensing box is provided on the upper left side of the inner and outer drums 2 of the shell, this embodiment utilizes the existing space on the upper right side of the inner and outer drums 2 of the shell to realize the installation of the fan assembly 43, so that the installation of the fan assembly 43 is realized without increasing the height of the washing machine shell, thereby improving the space utilization rate inside the shell.

[0142] In this embodiment, the fan assembly 43 is fixedly mounted on the housing 1 . Since the fan assembly is assembled into an integrated module with the evaporator, condenser, and heat exchange duct, the evaporator, condenser, and heat exchange duct are also fixedly mounted on the housing 1 .

[0143] Furthermore, the shell 1 includes a frame assembly 11, which includes a rear frame plate 111 and a left frame plate 113 and a right frame plate 112 fixed at both ends of the rear frame plate 111 and arranged opposite to each other. The volute is at least fixedly mounted on the rear frame plate 111 and the right frame plate 112. In this embodiment, the fan assembly 43 is fixedly mounted in at least two directions through the rear frame plate 111 and the right frame plate 112 to ensure the stability of its assembly.

[0144] Specifically, the volute includes an upper volute 434 and a lower volute 4311. The upper volute 434 and the lower volute 4311 are fixedly connected to enclose a volute chamber in which the fan impeller 4310 is set. A platform is set on the upper volute 434, and a fixing column 435 with a threaded hole inside is set on the lower volute 4311. The platform and the fixing column 435 are arranged along the circumference of the volute; the platform is fixedly overlapped on the right frame plate 112 / rear frame plate 111, and the fixing column 435 is fixed to the rear frame plate 111 / right frame plate 112 through a connecting piece.

[0145] In this embodiment, a first platform 433 and a second platform 434 are provided on the upper volute 434. The frame assembly includes a corner frame plate 114 that spans the right frame plate 112 and the rear frame plate 111. The first platform 433 is fixedly attached to the right frame plate 112, and the second platform 434 is fixedly attached to the corner frame plate 114. The fixing column 435 is fixed to the rear frame plate 111 via a connector. The corner frame plate 114 of this embodiment not only secures the fan assembly 43, making its installation more stable, but also increases the overall strength of the frame assembly, ensuring the stability of the entire washing machine.

[0146] This embodiment incorporates multi-directional fixing structures, such as a platform and fixing columns, into the fan assembly. Based on analysis of fixing stability and force angles, these structures must be positioned within a range no less than one-third of the fan assembly's diameter. They are secured to the entire machine housing with screws. This multi-directional fixing structure effectively ensures the fan assembly's stability when the outer drum washing or dehydration process causes vibrations within the machine housing.

[0147] During the drying process, the fan motor 4310 drives the fan impeller 4310 to rotate at a certain speed. The fan impeller 4310 running at high speed drives the internal circulation movement of the drying airflow, so that the airflow is sucked into the fan assembly 43 from the outer cylinder 2, and then flows to the heat exchange module at a certain speed, forming an airflow in the drying duct.

[0148] The drying process described in this embodiment refers to the high-speed operation of the fan assembly 43 via the fan motor 4310 during drying. Airflow within the circuit passes through the outer drum 2 through the outer drum outlet and is drawn into the fan assembly 43. Driven by the high-speed fan motor 4310 of the fan assembly 43, the airflow then undergoes centrifugal motion at a constant speed and enters the heat exchange duct. The air then re-enters the outer drum 2 and is drawn back into the drying circuit by the fan assembly 43, continuing the cycle.

[0149] See also Figure 18 As shown, the fan air inlet of this embodiment is connected to the outer drum air outlet 22 on the outer drum body 23 of the outer drum 2 via a flexible adapter 41. Since the fan assembly 43 is fixed to the frame assembly 11, the outer drum body 23 will vibrate during operation of the washing machine. Therefore, the flexible adapter 41 is used to connect the outer drum body 23 with the fan assembly 43 to prevent damage caused by the interaction force between the vibration of the outer drum body 23 and the fan assembly 43.

[0150] Furthermore, in this embodiment, the center of the air outlet 22 is set on the rear cylinder position on the central axis surface of the top of the outer cylinder body 23, and the flexible adapter 41 has a first connection port connected to the outer cylinder air outlet 22 and a second connection port connected to the fan air inlet. There is an eccentric distance between the central axis of the first connection port and the central axis of the second connection port, which is mainly to adapt to the connection between the fan assembly 43 located at the upper right corner of the outer cylinder and the outer cylinder air outlet 22 located at the center position of the top of the outer cylinder body 23.

[0151] In this embodiment, the first connection port is fastened to the air outlet of the outer cylinder via a first fastening clamp 437 , and the second connection port is fastened to the air inlet of the fan via a second fastening clamp 436 .

[0152] Specifically, this embodiment provides a flexible adapter 41 of a fan assembly that uses a rubber adapter to connect the drying duct and the outer drum, utilizing the stretchability and ductility of the rubber adapter. When the outer drum is performing washing, dehydration and other procedures and generates vibration or multi-directional force pulling, it ensures that the drying duct is not affected by vibration and maintains a complete closed circulation air duct system.

[0153] The rubber adapter described in this embodiment is installed at the top of the outer cylinder to connect the fan assembly and the outer cylinder; the connection position at the top of the outer cylinder is called the outer cylinder air outlet, wherein the fan assembly is placed to form a certain angle (within 90°) with the horizontal plane; the first connecting member 511 is installed at the front position of the outer cylinder to connect the air guide assembly 446 and the outer cylinder; in this assembly, the rubber adapter and the first connecting member are both flexible structures and materials that can generate a motion stroke.

[0154] Correspondingly, the outer drum air outlet is arranged at the top of the outer drum to reduce the length of the air circulation path, thereby reducing the resistance of the drying circulation air path, improving the drying efficiency, and also playing the role of a circulation air path.

[0155] The outer drum air outlet needs to be provided with a first filter 411 at the outer drum air outlet to filter the hair debris generated during the drying process.

[0156] Example 4

[0157] This embodiment specifically optimizes the assembly and structural improvement of the compressor assembly of the heat pump module, making better use of the space inside the shell for assembly, improving the space utilization rate inside the shell, ensuring the drying efficiency, and simplifying the installation process. The specific solution is as follows:

[0158] See also Figure 1-Figure 3 、 Figures 19-21 As shown, a drum washing machine with a heat pump drying function in this embodiment includes:

[0159] outer cylinder 2;

[0160] The frame assembly 11, the outer cylinder 2 is arranged in the inner space of the frame assembly 11;

[0161] And a heat pump module, including an evaporator, a condenser and a compressor 451. The condenser and the evaporator are integrated into a two-device module 44. The two-device module 44 is arranged above the outer tube 2. The compressor 451 is arranged on the frame assembly 11. The compressor 451 is connected to the two-device module 44 through a heat pump medium pipeline.

[0162] The drum washing machine of this embodiment has two modules 44 arranged above the outer drum 2, and the compressor 451 is arranged on the frame assembly 11 and located behind the outer drum 2. The reasonable position layout between the modules reduces production costs, rationally utilizes the internal space of the washing machine, and reduces the height of the entire machine.

[0163] See also Figure 20 As shown, the frame assembly 11 described in this embodiment includes a rear frame plate 111 and a left frame plate 113 and a right frame plate 112 fixed at both ends of the rear frame plate 111 and arranged opposite to each other, the bottom of the left frame plate 113 has a left bottom plate 118, and the bottom of the right frame plate 112 has a right bottom plate 117; the compressor 451 is fixedly mounted on the fixed bottom plate 116, and the two ends of the fixed bottom plate 116 are respectively fixed to one end of the left bottom plate 118 close to the rear frame plate 111 and one end of the right bottom plate 117 close to the rear frame plate 111.

[0164] In this embodiment, the compressor 451 is fixed to the frame assembly 11 by fixing the bottom plate 116, thereby reducing the displacement of the compressor 451 caused by vibration during operation, reducing the working resonance of the compressor 451, and making the whole machine run smoothly.

[0165] See also Figure 21 As shown, the compressor 451 described in this embodiment is fixed to the fixed base plate 116 through an assembly component; the assembly component includes an assembly bolt 4511 and a fastening nut 458, an assembly through hole is provided on the fixed base plate 116, and a fixing foot 459 is provided on the casing of the compressor 451, the assembly bolt 4511 passes through the assembly through hole and the fixing foot 459 in sequence from bottom to top, and the fastening nut 458 is fastened to the end of the assembly bolt 4511 extending out of the fixing foot 459.

[0166] Furthermore, the assembly component further includes a pre-tightening elastic washer 4510 , which is sleeved on the assembly bolt 4511 and located between the fixing foot 459 and the fixing base plate 116 .

[0167] Furthermore, an assembly profile 1161 is provided on the fixed base plate 116 , and the assembly profile 1161 matches the shape of the casing end of the compressor 451 . After the compressor 451 is fixedly installed on the fixed base plate 116 , the casing end of the compressor 451 abuts against the assembly profile 1161 .

[0168] Furthermore, the assembly through holes include multiple ones, which are evenly distributed along the periphery of the assembly profile 1161, and the fixing feet 459 include multiple ones, which are evenly distributed along the periphery of the casing of the compressor 451 and are arranged one-to-one corresponding to the assembly through holes.

[0169] During installation, the assembly through holes are assembled one-to-one with the fixed feet 459, and the assembly bolts 4511 pass through the assembly through holes, pre-tightening elastic washers 4510, and fixed feet 459 on the fixed base plate 116 from bottom to top, and are locked by the fastening nuts 458 arranged above the fixed feet 459. When assembled in place, the bottom of the compressor 451 abuts against the assembly pressure profile 1161, and the pre-tightening elastic washer 4510 provides a pre-tightening force for bolt locking and can absorb a certain amount of vibration energy, thereby reducing the risk of the bolt locking failing due to the vibration generated during the operation of the compressor. The assembly pressure profile provides locking feedback for the locking of the compressor and forms a certain structural limit in the horizontal direction, thereby improving the locking strength of the compressor.

[0170] See also Figure 20 As shown, in this embodiment, a heat dissipation fan 453 is provided on the left frame plate and / or the right frame plate, and the air outlet direction of the heat dissipation fan 453 is toward the compressor 451 for heat dissipation of the compressor. Figure 24 As shown, the rear frame plate 111 is provided with heat dissipation holes 119 for the heat dissipation air blown out by the heat dissipation fan 453 to flow out of the interior of the housing 1.

[0171] The heat pump module described in this embodiment further includes a two-device box for arranging the two-device modules. The two-device box has two air outlets, and the two air outlets are connected to the interior of the outer tube 2 through the air inlet duct 511.

[0172] Furthermore, the heat pump module described in this embodiment includes a fan assembly 43, an outer cylinder air outlet 22 is opened on the outer cylinder 2, and the fan assembly 43 is connected to the outer cylinder air outlet 22 through the air outlet duct 41. The two-device box has two-device box air inlets, and the two-device box air inlets are connected to the air outlet of the fan assembly.

[0173] The two-device modules and the fan assembly in the drum washing machine of this embodiment are arranged on the upper left or upper right side of the outer drum wall. The two-device modules are arranged at one end near the drum mouth of the outer drum, and the fan assembly is arranged at one end near the drum bottom of the outer drum.

[0174] The pipe connections between the compressor, evaporator and condenser in this embodiment are as follows:

[0175] See also Figure 22-25 As shown, the compressor 451 described in this embodiment is connected to a first heat pump medium pipeline 455 and a second heat pump medium pipeline 454, the evaporator is connected to a third heat pump medium pipeline 456 that is detachably connected to the first heat pump medium pipeline 455, and the condenser is connected to a fourth heat pump medium pipeline 457 that is detachably connected to the second heat pump medium pipeline 454.

[0176] In this embodiment, the compressor, evaporator, and condenser are separately connected to the heat pump medium pipeline. When the individual components are assembled within the housing, there is no interference between the components, making assembly easier. After the compressor, evaporator, and condenser are assembled separately, the corresponding heat pump medium pipelines are connected to achieve heat pump medium pipeline communication between the components. Therefore, the separate connection method of the heat pump pipeline in this embodiment simplifies the assembly sequence between the components and reduces production costs.

[0177] As an optional embodiment of this embodiment, the frame assembly 11 described in this embodiment includes a rear frame plate and a left frame plate 113 and a right frame plate 112 fixed to opposite ends of the rear frame plate 111. The rear frame plate 111 defines mounting holes 115. The connection points of the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, and the connection points of the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 correspond to the mounting holes 115. In this way, the mounting holes 115 on the frame assembly 11 are used for pipeline connection and disassembly and maintenance, simplifying assembly and reducing production and after-sales maintenance costs.

[0178] As an optional implementation of this embodiment, the evaporator and condenser described in this embodiment are both relatively fixedly mounted on the frame assembly 11 and located above the outer cylinder 2. The first heat pump medium pipeline 455 and the third heat pump medium pipeline 456, as well as the second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457, are all relatively fixedly connected. Because the evaporator and condenser are relatively fixedly mounted on the frame assembly 11, and the compressor is also relatively fixedly mounted on the frame assembly 11, relative displacement between the evaporator, condenser, and compressor does not occur, and a relatively fixed hard connection method can be used between the heat pump medium pipelines.

[0179] Specifically, the first heat pump medium pipeline 455 and the third heat pump medium pipeline 456 are both rigid pipes, and the first and third heat pump medium pipelines 455 and 456 are fixedly connected by a first rigid pipe joint. The second heat pump medium pipeline 454 and the fourth heat pump medium pipeline 457 are both rigid pipes, and the second and fourth heat pump medium pipelines 454 and 457 are fixedly connected by a second rigid pipe joint. Specifically, the first heat pump medium pipeline 455, the third heat pump medium pipeline 456, the second heat pump medium pipeline 454, and the fourth heat pump medium pipeline 457 are all copper or aluminum metal pipes, and the first and second rigid pipe joints are copper or aluminum pipe joints.

[0180] The heat pump module of this embodiment includes a fan assembly 43 and an outlet duct 41. The fan assembly 43 communicates with the interior of the outer drum 2 via the outlet duct 41, driving drying air between the outer drum 2 and the evaporator and condenser. The fan assembly 43 is mounted on the frame assembly 11, and the outlet duct 41 is a flexible, deformable duct. Because the fan assembly 43 is fixedly mounted on the frame assembly 11, the outer drum vibrates during operation, necessitating communication via the flexible, deformable duct.

[0181] As an optional embodiment of this embodiment, the evaporator and condenser described in this embodiment are both relatively fixedly mounted on the top of the circumferential wall of the outer tub 2. The first and third heat pump medium pipelines 455 and 456, as well as the second and fourth heat pump medium pipelines 454 and 457, are connected via flexible deformable tubes. Because the evaporator and condenser are both mounted on the outer tub, and the compressor is relatively fixedly mounted on the frame assembly 11, the outer tub vibrates during operation of the washing machine, resulting in relative displacement between the evaporator, condenser, and compressor. Therefore, the heat pump medium pipelines are connected using flexible connections that allow for relative motion.

[0182] Specifically, the first heat pump medium pipeline and the third heat pump medium pipeline are both hard pipes, and the flexible deformable pipe includes a first flexible rubber pipe, and the first heat pump medium pipeline and the third heat pump medium pipeline are connected to each other in a relatively movable manner through the first flexible rubber pipe;

[0183] The second heat pump medium pipeline and the fourth heat pump medium pipeline are both hard pipes, and the flexible deformable pipe includes a second flexible rubber pipe. The second heat pump medium pipeline and the fourth heat pump medium pipeline are connected to each other in a relatively movable manner through the second flexible rubber pipe.

[0184] At the same time, the heat pump module described in this embodiment includes a fan assembly 43, which is relatively fixedly mounted on the top of the outer tube 2. The outer tube 2 has an outer tube air outlet 22 at its top. The air inlet of the fan assembly 43 is directly fixedly connected to the outer tube air outlet 22, or the air inlet of the fan assembly 43 is fixedly connected to the outer tube air outlet 22 via an air outlet duct, and is used to drive the drying air between the outer tube and the evaporator and condenser. The fan assembly 43 is fixed to the outer tube and moves synchronously with the outer tube. The two are relatively stationary. Therefore, the air path connection between the fan assembly 43 and the outer tube 2 can be a hard connection.

[0185] The condenser and evaporator described in this embodiment are integrated into a two-device module. The heat pump module also includes a two-device box for setting the two-device module. The two-device box has two-device box air inlets, and the air outlet of the fan assembly is fixedly connected to the two-device box air inlets.

[0186] In this embodiment, a door seal is installed at the tube mouth of the outer tube, and the two-device box has two-device box air outlets, and the two-device box air outlets are connected to the door seal through an air inlet duct.

[0187] In this embodiment, the two components of the heat pump module and the compressor component are placed separately in the overall machine position. When the overall machine is assembled, the heat pump medium pipelines between the two components are welded separately, and then connected through the intermediate pipeline A after the two components are assembled in place.

[0188] The following beneficial effects are achieved through this invention:

[0189] (1) The two devices and the press are placed separately, which reduces the height of the entire machine and realizes the miniaturization of the heat pump type clothes processing device;

[0190] (2) The compressor is placed behind the cylinder and fixed on the bottom plate, making reasonable use of the internal space of the whole machine;

[0191] (3) The separate welding method of heat pump pipelines simplifies the assembly sequence between parts and reduces production costs;

[0192] (4) The mounting holes on the frame are used for pipe connection, which simplifies assembly and reduces production and after-sales maintenance costs.

[0193] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
